Abstract
Ovarian cancer (OC) is a deadly disease and lacks a precise marker for diagnosis worldwide. Our previous work has shown the overexpression of flotillin-1 (FLOT1) in OC tissue. To improve diagnostic sensitivity and accuracy, we evaluated the serum level of FLOT1 in OC patients and found that the serum concentration of FLOT1 as well as CA125 was significantly increased in patients with OC compared with healthy control (p < 0.01) and those with benign tumors (p < 0.05). The detection rate (above the upper limit of a cut-off value) of FLOT1 and CA125 was 77.78% and 72.22%, respectively, in patients with OC, which was increased to 88.89% in combination. The elevation of FLOT1 was confirmed in the serum of nude mice after the implantation of human OC cells. A high level of FLOT1 protein in the serum was positively correlated with the overexpression of FLOT1 protein in OC tissues. Furthermore, the level of m6A modification of FLOT1 mRNA was significantly high in OC cells compared with normal ovarian epithelial cells, leading to an increase in FLOT1 mRNA expression. Application of a methylation inhibitor, 3-deazaadenosine, decreased FLOT1 mRNA expression in OC cells and suppressed tumor formation in a xenograft mouse model. In conclusion, the current study demonstrated that FLOT1 is a novel serum biomarker of OC and can be targeted by m6A modification inhibition. These data highlight the potential application of FLOT1 as a diagnostic marker and a therapeutic target for patients with OC.

Tumor-associated antigens are associated with primary Sjögren's syndrome-related interstitial lung disease and disease activity. Clin Biochem 2025; 137:110927. [PMID: 40210147 DOI: 10.1016/j.clinbiochem.2025.110927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2024] [Revised: 03/18/2025] [Accepted: 04/07/2025] [Indexed: 04/12/2025]
Abstract
OBJECTIVES Tumor-associated antigens (TAAs) have been shown to be associated with a variety of connective tissue diseases. However, the role of TAAs in primary Sjögren's syndrome (pSS) patients is still unclear. This study aims to explore the correlation between TAA levels and systemic clinical manifestations and disease activity in pSS patients. METHODS Data were retrospectively collected from 108 patients with pSS (pSS group) and 100 healthy subjects (HCs group). Comparison of clinical characteristics and serological parameters between the TAA-positive group and the TAA-negative group. The independent risk factors of TAAs positivity were analyzed by univariate and multivariate regression, and the receiver operating characteristic curve was used to analyze the diagnostic performance of TAAs for pSS-associated interstitial lung disease (pSS-ILD). RESULTS Compared with the control group, the positivity rates of CEA, CA125, CA15-3, and CYFRA21-1 were higher, and the levels of serum CA125, CA15-3, and CYFRA21-1were higher in the pSS group. The incidence of ILD, pleural effusion, pericardial effusion, and ESSDAI ≥5 in the TAA-positive group was higher than in the TAA-positive group. Multivariate logistic regression analysis showed that the incidence of ILD was identified as an independent risk factor for TAA positivity. The AUC of CEA, CYFRA21-1, and NSE in the diagnosis of pSS-ILD were 0.690, 0.840, and 0.872, respectively, and the combined diagnosis could reach 0.952. CONCLUSION Certain TAA-positive rates and serum levels were increased in pSS patients. The TAA-positive group is correlated with the ESSDAI scores. ILD was an independent risk factor for TAA positivity, and CYFRA21-1 and NSE had the best diagnostic value in patients with pSS-ILD.

Abstract
Demons-Meigs (DM) syndrome is characterized by the association of a benign ovarian tumor most often a fibroma or fibrothecoma with pleural and intraperitoneal effusions. It is a rare pathological entity. We report the case of a 40-year-old female patient with typical DM syndrome, characterized by the coexistence of pleural and intraperitoneal effusions, an ovarian mass, and a CA-125 level of 633 IU/ml. Laparotomy revealed abundant ascites and a large right ovarian mass, which was subsequently removed. Histopathological examination confirmed an ovarian fibroma. DM syndrome has a favorable prognosis, and treatment is primarily based on the removal of the ovarian tumor, without the need for chemotherapy or other therapeutic approaches.

Abstract
PURPOSE To provide a comprehensive understanding and propose a strategy for the management of extragonadal malignant germ cell tumors (EMGCTs) arising from extracranial and nonvaginal sites. METHODS We retrospectively reviewed the cases of 12 patients with EMGCTs arising from extracranial and nonvaginal sites treated in our center over the past 38 years. Data on clinicopathological characteristics, treatment modalities, and follow-up information were analyzed. RESULTS Among 209 patients diagnosed with EMGCTs, 12 women (5.7%) with EMGCTs of extracranial and nonvaginal sites were identified. These patients had tumors in the sacrococcygeal region (n = 4), abdominal cavity (n = 3), groin region (n = 2), uterus (n = 2), and mediastinum (n = 1). The median age at diagnosis was 23 years. Symptoms included abnormal uterine bleeding (n = 3), abdominal discomfort (n = 3), compression symptoms (n = 3), palpable mass (n = 2), and asymptomatic (n = 1). Yolk sac tumors (YSTs) were the most common histologic type. The median level of serum alpha-fetoprotein (AFP), a sensitive tumor marker, was 8216 ng/ml (2.7-74,157 ng/ml). One patient started bleomycin/etoposide/cisplatin without a pathologic diagnosis based on clinical diagnosis (high AFP levels and imaging findings), and 11 patients started chemotherapy following tumor biopsy or surgical resection. During the follow-up, one patient suffered a recurrence, two patients were alive with disease, and nine patients were disease-free. CONCLUSIONS Extracranial and nonvaginal EMGCTs are a heterogeneous group of tumors due to their varied onset ages, location, and clinical presentation. An all-around clinical evaluation is crucial for selecting appropriate treatment. Most patients achieve a good prognosis after surgical resection and chemotherapy. Patients with these rare diseases may benefit from individualized treatment and timely referral to experienced medical centers.

Abstract
Liquid biopsy has emerged as a non-invasive cancer diagnosis and prognosis tool. Circular RNAs (circRNAs) have become promising biomarkers due to their stability and regulatory roles in cancer biology. This study aimed to evaluate the potential of hsa_circ_0008285 as a diagnostic biomarker for ovarian cancer (OC). 102 paired cancer and adjacent normal tissue samples, along with plasma from 98 OC patients, 42 polycystic ovary syndrome (PCO) patients, 35 endometriosis patients, and 93 healthy donors, were analyzed. Differentially expressed circRNAs were identified using Illumina HiSeq 2000 high-throughput sequencing in OC tissue samples (n = 4). Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to validate the expression of hsa_circ_0008285. Diagnostic efficacy and sensitivity were assessed using receiver operating characteristic (ROC) analysis. High-throughput sequencing identified hsa_circ_0008285 as the most significantly upregulated circRNA (P = 0.000012). qRT-PCR results confirmed increased expression of hsa_circ_0008285 in OC tissues and plasma compared to healthy controls (P < 0.0001). ROC analysis demonstrated an area under the curve (AUC) of 0.74 (95 % CI: 0.6567-0.8306, P < 0.0001), indicating moderate diagnostic potential. Notably, the combined detection of hsa_circ_0008285 and CA_125 improved diagnostic specificity and sensitivity. Correlation analysis revealed that hsa_circ_0008285 upregulation was associated with tumor size, differentiation, and T stage. These findings suggest that hsa_circ_0008285 holds promise as a non-invasive biomarker for the diagnosis of OC, with potential applications in clinical practice.

Abstract
BACKGROUND Ovarian cancer has the highest mortality rate among gynecological cancers, making early detection crucial, as the five-year survival rate drops from 92% with early-stage diagnosis compared to 31% with late-stage diagnosis. Current diagnostic methods such as histopathological examination and detection of cancer antigen 125 and human epididymis protein 4 biomarkers are either invasive or lack specificity and sensitivity. However, the Papanicolaou (Pap) test, which is widely used for cervical cancer screening, shows the potential for detecting ovarian cancer by identifying tumor DNA in cervical scrapings. Since aberrant DNA methylation patterns are linked to cancer progression, DNA methylation offers a promising avenue for early diagnosis. Therefore, this study aimed to develop a methylation-based machine-learning model to stratify patients with ovarian cancer from the cervical scraping samples collected via Pap test. RESULTS Cervical scrapings were collected by gynecologists using conventional Pap smears. In total, 160 samples were collected: 95 normal, 37 benign, and 28 malignant. Methylation data were generated using the Illumina Infinium MethylationEPIC BeadChip array, which contains approximately 850,000 CpG loci. Methylation data were initially divided into training and testing sets in a 3:1 ratio comprising 120 and 40 samples, respectively. A two-step methylation-based model was trained using the training data for classification: a principal component analysis (PCA) model, consisting of 30 features, to classify samples as normal or tumor; then a gradient boosting model, containing 16 features, to further stratify tumor samples as benign or malignant. The two-step model achieved an accuracy of 0.88 and an F1-score of 0.86 on the testing data. Furthermore, an over-representation analysis was conducted to explore the functions associated with genes mapped from differentially methylated positions (DMPs) in comparisons between normal and tumor samples, as well as between benign and malignant samples. These results suggest that DMPs may be associated with olfactory transduction when comparing normal versus tumor samples, and immune regulation when comparing benign and malignant samples. CONCLUSIONS Our two-step model shows promise for predicting ovarian cancer and suggests that cervical scrapings may be a viable alternative for sample collection during screening.

Abstract
Ovarian cancer (OC), a leading cause of gynecological cancer mortality, is frequently detected at advanced stages due to asymptomatic early progression. This study investigates plasma-based untargeted metabolomics for identifying biomarkers to screen and differentiate ovarian tumors (OT). Plasma samples from OC, benign ovarian tumors (BOT), and healthy controls (HC) were analyzed. Samples were randomized into train and test sets, with differential metabolites screened via two-tailed Student's t-test and partial least squares discriminant analysis. ROC models evaluated discriminatory capacity. Key metabolites demonstrated high predictive value: TMAO and hippuric acid distinguished OT from HC (AUC > 0.95), while linoleic acid, alpha-linolenic acid, and arachidonic acid (AUC > 0.9) further supported OT screening. Kynurenine differentiated OC from BOT (AUC = 0.808). Reduced levels of specific lysophosphatidylcholines (LPC (17:0/0:0), LPC (15:0/0:0)) also distinguished OT from HC (AUC = 0.771-0.89). These findings suggest plasma metabolomics holds promise for noninvasive biomarker discovery in OT screening and distinguishing between malignant and benign cases, though further validation of metabolite quantification is warranted prior to clinical application.

Abstract
We aimed to investigate the prognostic role of CEACAM1 and to construct a radiomic model to predict CEACAM1 expression and prognosis in ovary cancer (OC). Sequencing data and CT scans in OC were sourced from TCGA and TCIA databases. CEACAM1 expression was assessed by Cox regression analyses, Kaplan-Meier curves and GSVA enrichment analysis. Furthermore, radiomic features were extracted from CT scans and selected by LASSO and ROC. The selected radiomic features were used to construct a radiomic model to predict CEACAM1 expression. In addition, the radiomic score (RS) and its relationship with OC survival were investigated by Kaplan-Meier and ROC curves. At last, RS and clinical features were included into LASSO, using nomogram to predict OC prognosis. Cox regression analyses showed that CEACAM1 expression was an independent prognostic factor and associated with immune cell infiltration in OC. By LASSO and ROC, six radiomic features were selected and used to construct a radiomic model. The PR, calibration, DCA and ROC curves revealed the good performance and clinical utility of the radiomic model to predict CEACAM1 expression. In addition, RS based on radiomic features was found to be associated with OC survival. At last, a nomogram based on RS, age, chemotherapy and tumor residual disease was constructed and was found to have high accuracy in predicting OC prognosis. For the first time, our study constructed a radiomic model to predict CEACAM1 expression and prognosis of OC patients. Those findings may guide novel diagnosis and treatment for OC patients.

Abstract
Background: Serum biomarkers such as Carcinoma Antigen 125 (CA125) and Human Epididymis Protein 4 (HE4) are widely used in the diagnosis and prognosis of gynecological malignancies. Serum biomarkers such as CA125 and HE4 represent essential tools in improving early detection, risk stratification, and therapeutic decision-making for gynecological malignancies. However, their role in identifying uterine sarcomas remains debated. This systematic review and case series aims to examine the diagnostic and prognostic significance of CA125 and HE4 in uterine sarcomas. Methods: A systematic review was performed on studies investigating serum CA125 and HE4 levels in uterine sarcomas. A case series of all uterine sarcomas treated at the Campus Bio-Medico Gynecology Unit of Rome from 2010 to 2020 was analyzed. Results: The analysis of the 11 selected studies allowed us to investigate the role of CA125 in uterine sarcomas. No studies analyzing the role of HE4 in monitoring the disease were found. A total of 16 patients with confirmed uterine leiomyosarcoma were included in our case series. Conclusions: Neither CA125 nor HE4 can currently be considered definitive biomarkers for the diagnosis of uterine leiomyosarcomas. However, they may serve as useful adjuncts in the differential diagnosis between leiomyomas and leiomyosarcomas, particularly in reproductive-age patients.

The impact of the COVID-19 pandemic on the diagnosis, treatment, and prognosis of ovarian cancer in the United States: a retrospective cohort study based on the SEER database. Discov Oncol 2025; 16:545. [PMID: 40244485 PMCID: PMC12006593 DOI: 10.1007/s12672-025-02205-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2024] [Accepted: 03/21/2025] [Indexed: 04/18/2025] Open
Abstract
BACKGROUND The COVID-19 pandemic has significantly impacted cancer diagnosis, treatment, and prognosis; however, its effects on ovarian cancer remain unclear. METHODS This multicenter retrospective study utilized the Surveillance, Epidemiology, and End Results database to compare changes in the diagnosis, treatment, prognosis, and risk factors among ovarian cancer patients pre- and post-COVID-19 pandemic. Patients diagnosed before the pandemic (pre-COVID-19 group) and those diagnosed during the pandemic (post-COVID-19 group) were matched through 1:1 propensity score matching. Kaplan-Meier analysis compared cancer-specific survival (CSS) and overall survival (OS). Factors associated with survival were identified by the Cox proportional hazards model, while a competing risks model was used to determine factors associated with cancer-specific death. RESULTS A total of 9,112 ovarian cancer patients were included in the study, with 4,536 diagnosed before COVID-19 and 4576 diagnosed during COVID-19. The results showed that the post-COVID-19 group presented at a more advanced stage had lower tissue differentiation, experienced more delayed treatments, and received fewer surgical interventions. Although there was no significant difference in survival between the pre-COVID-19 group and the post-COVID-19 group, patients with delayed treatment had a worse prognosis than those without delayed treatment. Additionally, we identified independent factors associated with survival outcomes, including age, tumor grade, clinical stage, pathological stage, specific histology, treatment delays, surgical intervention, and systemic therapy. CONCLUSIONS The survival outcomes of the pre-COVID-19 group and the post-COVID-19 group were relatively consistent, likely due to the short follow-up. Future research is necessary to continue monitoring the outcomes of patients in the post-COVID-19 group to determine its long-term impact.

Integrating multi-omics data reveals the antitumor role and clinical benefits of gamma-delta T cells in triple-negative breast cancer. BMC Cancer 2025; 25:623. [PMID: 40197136 PMCID: PMC11974128 DOI: 10.1186/s12885-025-14029-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2024] [Accepted: 03/26/2025] [Indexed: 04/09/2025] Open
Abstract
BACKGROUND Gamma-delta (γδ) T cells are a critical component of the tumor microenvironment and have been recognized as a promising biomarker and target for cancer therapy. Increasing evidence suggests that γδT cells play distinct roles in different cancers. However, the impact of γδT cells in breast cancer remains controversial. METHODS In this study, we investigated the role of γδT cells in breast cancer using a comprehensive approach, including bulk and single-cell sequencing, radiomics based on magnetic resonance imaging (MRI), genomic data, and immunohistochemistry. Single-cell RNA profiling was used to infer the potential lineage evolution of γδT cells and their interactions with other immune cells. Bulk RNA sequencing was included to uncover the heterogeneity in signaling pathways, as well as radiotherapy and immunotherapy responses, among patients with varying levels of γδT cell abundance. Genomic analysis was used to recognize the critical gene mutations with the infiltration of γδT cells. Immunohistochemistry was performed to validate the prognostic value of γδT cells in breast cancer patients. Lastly, radiomics was used to establish a correlation between the abundance of γδT cells and the features of MRI images. RESULTS The γδT cell infiltration was closely associated with favorable prognosis in triple-negative breast cancer (TNBC) but not in other subtypes of breast cancer. γδT cells may exert antitumor effects through intrinsic lineage evolution or interact with antigen-presenting cells through ligand-receptor pairs. Patients with a high γδT cell abundance may benefit more from chemotherapy or radiotherapy alone than their combination. Additionally, patients with a high γδT cell abundance were more likely to benefit from immunotherapy. Finally, we established a radiomic model based on dynamic contrast-enhanced-MRI, which indicated the potential for estimating the γδT cell abundance for patients with TNBC. CONCLUSION Our study provides novel insight and a theoretical basis for individualized therapy of patients with TNBC based on γδT cells.

Abstract
BACKGROUND The clinical prognostic factors for ovarian clear cell carcinoma (OCCC) are limited, and we aim to construct a model to predict the survival of OCCC patients. METHODS Data were extracted from the SEER database for patients diagnosed with OCCC. Cox regression analyses were used to identify independent risk factors for OCCC. Two nomograms were developed, and the results were evaluated comprehensively by C-index, ROC curve, calibration curve, and DCA curve. Patients diagnosed with OCCC were used as the validation set to verify the model. RESULTS A total of 1855 OCCC patients from the SEER database were used as the training set, and 101 patients from our hospital were used as the validation set. Cox regression analysis of the independent risk factors affecting the prognosis of OCCC was used to construct nomograms. The C-index of the training set OS was 0.76, and the validation set OS was 0.75. The AUC of the training set OS is 0.803, 0.794, and 0.802 for 1, 3, and 5 years, and 0.774, 0.800, and 0.923 for the validation set. The calibration curve and DCA curve also showed that OS and CSS have good predictive power. CONCLUSIONS A nomogram based on 8 prognostic factors analyzed by Cox regression can predict the prognosis of OCCC patients effectively.

Abstract
BACKGROUND Accurate early diagnosis of ovarian cancer is crucial. The objective of this research is to create a comprehensive model that merges clinical variables, O-RADS, and deep learning radiomics to support preoperative diagnosis and assess its efficacy for sonographers. MATERIALS AND METHODS Data from two centers were used: Center 1 for training and internal validation, and Center 2 for external validation. DL and radiomics features were extracted from transvaginal ultrasound images to create a DL radiomics model using the LASSO method. A machine learning model ensemble was created by merging clinical variables, O-RADS scores, and DL radiomics model predictions. The model's effectiveness was evaluated by measuring the area under the receiver operating characteristic curve (AUC) and analyzing its impact on improving the diagnostic skills of sonographers. Moreover, the model's additional usefulness was assessed through integrated discrimination improvement (IDI), net reclassification improvement (NRI), and subgroup analysis. RESULTS The ensemble model demonstrated superior diagnostic performance for ovarian cancer compared to standalone clinical models and clinical O-RADS models. Notably, there were significant improvements in the NRI and IDI across all three datasets, with p-values < 0.05. The ensemble model exhibited exceptional diagnostic performance, achieving AUCs of 0.97 in both the internal and external validation sets. Moreover, the implementation of this ensemble model substantially improved the diagnostic precision and reliability of sonographers. The sonographers' average AUC improved by 11 % in the internal validation set and by 7.7 % in the external validation set. CONCLUSIONS The ensemble model significantly enhances preoperative ovarian cancer diagnosis accuracy and improves sonographers' diagnostic capabilities and consistency.

Abstract
Tumors are among the most predominant health problems in the world, and the annual incidence of cancer is increasing globally; therefore, there is an urgent need to identify effective therapeutic targets. Chloride intracellular channel 4 (CLIC4) belongs to the family of chloride intracellular channels (CLICs), which are widely expressed in various tissues and organs, such as the brain, lung, pancreas, colorectum, and ovary, and play important roles in promoting apoptosis, promoting angiogenesis, maintaining normal proliferation of endothelial cells, and regulating the assembly and reconstruction of the cytoskeleton. The expression and function of CLIC4 in tumors varies. It has been reported that CLIC4 is low expressed in gastric cancer, skin cancer and prostate cancer, suggesting a tumor suppressor role. Interestingly, CLIC4 is overexpressed in pancreatic, ovarian and breast cancers, indicating a cancer-promoting role. CLIC4 expression is dysregulated in some solid tumors, which may be because CLIC4 is involved in the growth, migration or invasion of some cancer cells through various mechanisms. Regulation of CLIC4 expression may be a potential therapeutic strategy for some tumors. CLIC4 may be a promising therapeutic target and a biomarker for some cancers. In this study, we review the role of CLIC4 in several cancers and its value in the diagnosis and treatment of tumors.

Predictive Factors of Non-Elevation of Carcinoembryonic Antigen 125 in Acute Heart Failure. Life (Basel) 2025; 15:494. [PMID: 40141838 PMCID: PMC11944017 DOI: 10.3390/life15030494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2025] [Revised: 03/01/2025] [Accepted: 03/07/2025] [Indexed: 03/28/2025] Open
Abstract
This study aims to analyze the factors associated with the lack of carbohydrate antigen 125 (CA-125) elevation in cases of acute heart failure (HF) decompensation. This retrospective study was conducted on 3167 consecutive patients admitted for acute HF in the cardiology department of a referral hospital (June 2019 to June 2024). Admissions from outpatient clinics (n: 1018) and transfers from other hospitals (n: 752) were excluded. The variables of interest included clinical, echocardiographic, therapeutic, and analytical factors. Low CA-125 levels were defined as values ≤ 50 U/mL. A total of 1397 patients were included, of whom 515 had normal CA-125 levels and 882 had elevated levels. Clinically, independent predictors of low CA-125 were sinus rhythm on electrocardiogram (OR: 1.42, 95% CI: 1.12-1.64; p: 0.003) and sleep apnea-hyponpnea syndrome (OR: 1.76, 95% CI: 1.15-2.70; p: 0.009). Echocardiographically, inferior vena cava collapse greater than 50% with inspiration was associated with low CA-125 (OR: 1.78, 95% CI: 1.19-2.69; p = 0.005), as well as with non-severe right ventricular dysfunction. (OR: 2.42; IC95%: 1.39-4.20; p: 0.002). Analytically, elevated NT-proBNP levels were associated with elevated CA-125 levels (OR: 0.99; IC95%: 0.99-0.99; p: 0.006). Survival was higher in the group with CA-125 ≤ 50 U/mL (p: 0.019). Conversely, as CA-125 values increased, mortality also rose. In conclusion, the absence of CA-125 elevation in patients admitted for acute HF is associated with sinus rhythm, sleep apnea-hyponpnea syndrome, low NT-proBNP levels, and inferior vena cava collapse greater than 50% with inspiration.

Zhao H, Zhang Y, Zhu Q. Long-term trends analysis of the incidence and mortality in patients with ovarian cancer: a large sample study based on SEER database. Postgrad Med J 2025; 101:302-312. [PMID: 39475117 DOI: 10.1093/postmj/qgae143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2024] [Revised: 09/08/2024] [Accepted: 09/29/2024] [Indexed: 03/18/2025]
Abstract
BACKGROUND To analyze long-term trends of the incidence and mortality of ovarian cancer in the United States. METHODS Patients diagnosed with ovarian cancer were obtained from the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2017. Joinpoint regression analysis was used to analyze the incidence and mortality trend, and the changes were reported as average annual percentage change (AAPC) with a 95% confidence interval (CI). Kaplan-Meier survival curve and Cox regression analyses were utilized for survival analysis. RESULTS A total of 74 682 patients were included, among whom 49 491 (66.27%) died and 44 487 (59.57%) died from ovarian cancer. The mean age was 61.95 ± 15.23 years. The incidence of ovarian cancer showed a decreased trend from 2000 to 2017 with an AAPC of -1.9 (95%CI: -2.0, -1.7). Both the overall mortality and cancer-specific mortality for ovarian cancer decreased from 2000 to 2017, with AAPCs of -5.0 (95%CI: -5.7, -4.2) and -4.6 (95%CI: -5.4, -3.8), respectively. There was a significant decrease in the incidence and mortality of patients with the distant SEER stage, histological subtypes of serous and malignant Brenner carcinoma, and grades II and III from 2000 to 2017. Older age, Black race, histological subtypes of carcinosarcoma, higher tumor grade, and radiotherapy were associated with poorer overall survival and cancer-specific survival, whereas higher income, histological subtype of endometrioid, and surgery were associated with better survival. CONCLUSION This study provided evidence of a statistically significant decrease in the incidence and mortality of ovarian cancer from 2000 to 2017. Key message What is already known on this topic? Ovarian cancer is one of the most common tumors in women, with high morbidity and mortality. However, trends in long-term morbidity and mortality of patients with ovarian cancer have not been reported. What this study adds Overall incidence and mortality for ovarian cancer showed a decreased trend from 2000 to 2017, and trends in incidence and mortality varied by stage, histological subtype, and tumor grade. Factors associated with overall survival and cancer-specific survival also differ. How this study might affect research, practice, or police This study provides evidence of long-term trends in ovarian cancer incidence and mortality from 2000 to 2017.

Effects of Clinical Covariates on Serum miRNA Expression among Women without Ovarian Cancer. Cancer Epidemiol Biomarkers Prev 2025; 34:385-393. [PMID: 38780899 PMCID: PMC11873719 DOI: 10.1158/1055-9965.epi-23-1355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Revised: 02/26/2024] [Accepted: 05/20/2024] [Indexed: 05/25/2024] Open
Abstract
BACKGROUND Serum miRNAs are potential biomarkers for ovarian cancer; however, many factors may influence miRNA expression. To understand potential confounders in miRNA analysis, we examined how sociodemographic factors and comorbidities, including known ovarian cancer risk factors, influence serum miRNA levels in women without ovarian cancer. METHODS Data from 1,576 women from the Mass General Brigham Biobank collected between 2012 and 2019, excluding subjects previously or subsequently diagnosed with ovarian cancer, were examined. Using a focused panel of 179 miRNA probes optimized for serum profiling, miRNA expression was measured by flow cytometry using the Abcam FirePlex assay and correlated with subjects' electronic medical records. RESULTS The study population broadly reflected the New England population. The median age of subjects was 49 years, 34% were current or prior smokers, 33% were obese (body mass index > 30 kg/m2), 49% were postmenopausal, and 11% had undergone prior bilateral oophorectomy. Significant differences in miRNA expression were observed among ovarian risk factors such as age, obesity, menopause, BRCA1 or BRCA2 germline mutations, or existence of breast cancer in family history. Additionally, miRNA expression was significantly altered by prior bilateral oophorectomy, hypertension, and hypercholesterolemia. Other variables, such as smoking; parity; age at menarche; hormonal replacement therapy; oral contraception; breast, endometrial, or colon cancer; and diabetes, were not associated with significant changes in the panel when corrected for multiple testing. CONCLUSIONS Serum miRNA expression patterns are significantly affected by patient demographics, exposure history, and medical comorbidities. IMPACT Understanding confounders in serum miRNA expression is important for refining clinical assays for cancer screening.

Abstract
BACKGROUND Ovarian cancer is frequently occurring and fatal for women. CA-125 is important in the screening, diagnosis, and treatment of ovarian cancer. This review study was conducted to explore the influence of CA-125 in addressing ovarian cancer. METHODS To investigate the role of CA-125 in ovarian cancer, we conducted a comprehensive search for high-quality articles in the Medline, Web of Science Core Collection and Scopus databases using the keywords "ovarian cancer," "ovarian carcinoma," "ovarian neoplasms," and "CA-125" from the 2000 to 2024. We included full-text, peer-reviewed articles in English with relevant keywords published since 2000. We excluded case reports, commentaries, letters to the editor, books, case series, systematic reviews, animal studies, and articles that were not accessible in full text. RESULTS After screening the 7947 records, 88 studies were included in this review. In the literature review, it was found that researchers utilized CA-125 for diagnosing ovarian cancer, its predicting, evaluating treatment response, assessing ovarian cancer survival, and early detection of recurrence. In some cases, researchers employed additional tumor markers alongside CA-125 to enhance the test's sensitivity. CONCLUSION CA-125 has become a pivotal marker for ovarian cancer. Its role in the diagnosis, treatment, and ongoing assessment of ovarian cancer cannot be overstated. Continuous monitoring of CA-125 levels can provide comprehensive insights, and categorizing patients as low-risk or high-risk based on CA-125 levels could lead to better outcomes. Integrating CA-125 with other biomarkers may enhance the accuracy of the test and elevate its relevance in patient care.

Abstract
Extracellular vesicles (EVs), as cell-derived small vesicles, facilitate intercellular communication within the tumor microenvironment (TME) by transporting biomolecules. EVs from different sources have varied contents, demonstrating differentiated functions that can either promote or inhibit cancer progression. Thus, regulating the formation, secretion, and intake of EVs becomes a new strategy for cancer intervention. Advancements in EV isolation techniques have spurred interest in EV-based therapies, particularly for tumor immunotherapy. This review explores the multifaceted functions of EVs from various sources in tumor immunotherapy, highlighting their potential in cancer vaccines and adoptive cell therapy. Furthermore, we explore the potential of EVs as nanoparticle delivery systems in tumor immunotherapy. Finally, we discuss the current state of EVs in clinical settings and future directions, aiming to provide crucial information to advance the development and clinical application of EVs for cancer treatment.

Abstract
Background/Objectives: The prognosis of endometriosis-related ovarian clear cell carcinoma (OCCC) versus non-endometriosis-associated OCCC remains unclear. We examined the impact of endometriosis on OCCC diagnosis and progression and assessed whether prior surgical intervention for endometriotic ovarian cysts affects prognosis. Methods: In this retrospective study (2006-2024), OCCC patients were classified as non-endometriosis-associated or endometriosis-related. A subgroup analysis compared endometriosis-related OCCC patients with and without a history of endometriotic ovarian cyst surgery. Results: The average CA-125 level was 104.20 (29.90, 347.70) in the non-endometriosis-associated OCCC group and 80.70 (32.40, 247.90) in the endometriosis-related OCCC group (p = 0.32). Early-stage diagnosis occurred in 62.77% and 75.21% of these groups, respectively (p = 0.046). The average age at diagnosis was 53.95 ± 9.71 years for the non-endometriosis-associated group and 45.68 ± 7.98 years for the endometriosis-related group (p < 0.001). Mortality or poor prognosis was observed in 24.11% and 17.80% of these groups, respectively (p = 0.226). In endometriosis-related OCCC, comparisons were made between patients with and without a history of endometriotic ovarian cyst surgery. The average age at diagnosis was 45.84 ± 8.24 years for those without a surgical history and 44.71 ± 6.35 years for those with a surgical history (p = 0.59). Early-stage diagnosis was observed in 77.23% and 62.50%, respectively (p = 0.339). Mortality or poor prognosis occurred in 14.85% of those without a surgical history and 35.29% of those with a surgical history (p = 0.008). The hazard ratio for women with a surgical history was 3.48 (1.29-8.69) (p = 0.008). The incidence rate was 3.17 per 1000 person-years (PYRs) for individuals without surgery and 13.36 per 1000 PYRs for those with a history of surgical intervention (p = 0.008). Conclusions: Endometriosis did not impact the prognosis of women with OCCC. However, women with endometriosis-related OCCC were diagnosed at earlier stages and at younger ages. A history of endometriotic ovarian cyst surgery did not influence OCCC detection but was linked to poorer survival outcomes.

Abstract
BACKGROUND The existing drugs for ovarian cancer (OC) are unsatisfactory and thus new drug targets are urgently required. We conducted proteome-wide Mendelian randomization (MR) and colocalization analysis to pinpoint potential targets for OC. METHODS Data on protein quantitative trait loci (pQTL) for 734 plasma proteins were obtained from large genome-proteome-wide association studies. Genetic associations with OC were derived from the Ovarian Cancer Association Consortium, which included 25,509 cases and 40,941 controls. MR analysis was performed to evaluate the association between the proteins and the OC risk. Colocalization analysis was conducted to check whether the identified proteins and OC shared causal variants. In addition, the phenome-wide MR analysis was performed to clarify protein associations across the phenotype, and drug target databases were examined for target validation. RESULTS Genetically predicted circulating levels of 44 proteins were associated with OC risk at Benjamini-Hochberg correction. Genetically predicted 17 proteins had evidence of the increased risk of OC (CLEC11A, MFAP2, TYMP, PDIA3, IL1R1, SPINK1, PLAU, DKK2, IL6ST, DLK1, LRRC15, CDON, ANGPTL1, SEMA4D, AKR1A1, TNFAIP6, and FCGR2B); 27 proteins decreased the risk of OC(SIGLEC9, RARRES1, SPINT3, TMEM132A, HAVCR2, CNTN2, TGFBI, GSTA1, HGFAC, TREML2, GRAMD1C, ASAH2, CPNE1, CCL25, MAPKAPK2, POFUT1, PREP, NTNG1, CA10, CACNA2D3, CA8, MAN1C1, MRC2, IL10RB, RBP4, GP5 and CALCOCO2). Bayesian colocalization demonstrated that GRAMD1C, RBP4, PLAU, PDIA3, MFAP2, POFUT1, MAN1C1 and DKK2 shared the same variant with OC. The phe-MR analyses assessed the side effects of these 44 identified proteins, and the drug target database offered information on both approved and investigational indications. CONCLUSION This study provides proof of a causal relationship between genetically predicted 44 proteins associated with OC risk, which could serve as promising drug targets for OC.

Abstract
In this study, the influence of glycoproteomic changes, specifically MUC16, on NK cell-mediated immunotherapy response in ovarian cancer is explored. Analysis of glycoprotein data from the CPTAC database identified significant upregulation of MUC16 in ovarian cancer tissues, associated with tumor invasiveness and immune evasion. Experimental findings showed that MUC16 knockdown increased NK cell cytotoxicity, decreased invasiveness, and boosted NK cell activation, while MUC16 overexpression resulted in the opposite effects. In vivo experiments demonstrated that MUC16 knockdown suppressed tumor growth, enhanced NK cell infiltration, and bolstered NK cell activation, underscoring the potential of MUC16 as a target for novel immunotherapy approaches in ovarian cancer treatment.

Abstract
Uterine adenomyosis, a common benign tumor disease in gynecology, mainly manifested as chronic pelvic pain, menstrual disorders, dysmenorrhea, etc., has a great impact on patients' daily life and work. Compared with traditional surgery and drug therapy, uterine artery embolization (UAE), as a new treatment with less trauma, faster recovery and uterine preservation, can relieve pain while preserving normal physiological and reproductive functions of the uterus, which is favored by the majority of patients. In this study, the patients were divided into two groups based on magnetic resonance imaging (MRI) test. Their serum CA125 level was detected, and the degree of symptom relief and health index were evaluated, aiming to explore the clinical efficacy and influencing factors of UAE in the treatment of adenomyosis. The results showed that before UAE, CA125 level in group B was significantly higher than that in group A, and 2 days after UAE, CA125 level in both groups was lower than before treatment, indicating that the serum CA125 level may be related to the type of adenomyosis, but UAE has a good therapeutic effect on both focal and diffuse adenomyosis. 3 months after interventional treatment, the patients had significantly reduced symptoms with dramatically improved health status and the VAS pain score was significantly reduced, indicating that UAE can significantly improve the clinical symptoms of patients with adenomyosis. Uterine artery embolization was performed in both groups. No serious complications occurred during the operation, and the technical success rate reached 100%. In summary, UAE, as a minimally invasive treatment, has obvious and significant clinical effects in the treatment of adenomyosis, and is an important alternative treatment for adenomyosis.

Integrative Analysis of Gene Expression and Promoter Methylation to Differentiate High-Grade Serous Ovarian Cancer from Benign Tumors. Biomedicines 2025; 13:441. [PMID: 40002854 PMCID: PMC11853219 DOI: 10.3390/biomedicines13020441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2025] [Revised: 02/03/2025] [Accepted: 02/08/2025] [Indexed: 02/27/2025] Open
Abstract
Background: Ovarian cancer (OC) is the third most common and second most lethal onco-gynecological disease in the world, with high-grade serous ovarian cancer (HGSOC) making up the majority of OC cases worldwide. The current serological biomarkers used for OC diagnosis are lacking sensitivity and specificity, thus new biomarkers are greatly needed. Recently, the chromatin remodeling complex gene ARID1A, Notch and Wnt pathway gene expression, as well as HOX-related gene promoter methylation have been linked with promoting OC. Methods: In this pilot study, 10 gene expression biomarkers and 4 promoter methylation biomarkers were examined as potential diagnostic and prognostic indicators of OC in 65 fresh-frozen gynecologic tumor tissues. Results: Out of 10 genes analyzed, the expression of eight biomarkers was significantly reduced in OC cases compared to benign, and HOX-related gene promoter methylation significantly increased in OC tumors. Out of 14 biomarkers, CTNNB1 showed the best single biomarker separation of HGSOC from benign cases (AUC = 0.97), while a combination of the seven Notch pathway-related gene expressions (NOTCH1, NOTCH2, NOTCH3, NOTCH4, DLL1, JAG2, and HES1) demonstrated the best separation of HGSOC from the benign cases (AUC = 1). Conclusions: The combination of multiple gene expression or gene promoter methylation biomarkers shows great promise for the development of an effective biomarker-based diagnostic approach for OC.

Abstract
Background Ovarian cancer, particularly high-grade serous ovarian cancer (HGSOC), is the most lethal gynecological tumor, with most patients experiencing recurrence within 5 years. Long-term survival in HGSOC patients with advanced stages is exceedingly rare. Case summary We report a case of advanced HGSOC with exceptional long-term recurrence-free survival following initial treatment. In June 2009, the patient underwent suboptimal cytoreductive surgery for stage IIIC ovarian cancer, including total hysterectomy, bilateral salpingo-oophorectomy, omentectomy, appendectomy, and resection of mesenteric and peritoneal lesions. Postoperatively, residual lesions were observed in the mesenteries and para-aortic lymph nodes. Despite unfavorable prognostic factors (advanced stage, aggressive pathology, and incomplete resection), the patient showed remarkable chemosensitivity, remaining recurrence-free for 15 years. Conclusion The factors influencing long-term survival in HGSOC patients are not yet fully understood. We present this rare case to contribute data for further studies on long-term survival in advanced HGSOC.

Abstract
Introduction Women with low-risk endometrial cancer, as defined by the Korean Gynecologic Oncology Group (KGOG) criteria, have a low risk of lymph node metastasis and an excellent prognosis without lymphadenectomy. However, it is unclear whether lymphadenectomy should be performed in premenopausal women who meet the KGOG criteria other than elevated cancer antigen 125 (CA125) levels, because the CA125 level can be elevated by benign conditions. We investigated the patterns of metastasis and recurrence to assess the value of lymphadenectomy in this population. Methods Premenopausal women with endometrial cancer meeting the KGOG criteria, except for those with elevated CA125 levels, were eligible. The characteristics of the eligible women were collected from seven institutes in the Republic of Korea by reviewing their medical records. Recurrence-free survival (RFS) was estimated using the Kaplan-Meier method and compared using the log-rank test. Results Seventy-three patients were included. Of 62 women who underwent lymphadenectomy, only two (3.2%) had lymph node metastasis. Eighteen women (24.7%) received adjuvant therapy. At a median follow-up of 59 months, the 5-year RFS was 88.8%. Five women (7%) experienced recurrence, two had lymph node recurrence, and three had non-nodal recurrence. RFS was similar between the women who did and did not undergo lymphadenectomy (P=0.737). Conclusion Premenopausal women who had elevated CA125 levels but met all other KGOG criteria showed a low risk of lymph node metastasis and recurrence as well as a good prognosis. Therefore, lymphadenectomy can be omitted in this population.

Abstract
BACKGROUND This study aimed to evaluate the efficacy and safety of pegylated liposomal doxorubicin (PLD) for patients with partially platinum-sensitive, platinum-resistant, or platinum-refractory ovarian cancer. METHODS Patients with partially platinum-sensitive, platinum-resistant, or platinum-refractory ovarian cancer were recruited in this prospective, open-label, single-arm, multicenter study. Eligible patients were given 4-6 cycles of PLD (40 mg/m2 on day 1, every 4 weeks). The primary endpoint was progression-free survival (PFS). Secondary endpoints were overall survival (OS), objective response rate (ORR), disease control rate (DCR), quality of life, and safety. Exploratory endpoints included the change trend of CA125 and platinum-free interval. RESULTS Between June 2017 and November 2020, 167 eligible patients were included in the full analysis set. The median PFS and OS were 6.8 months (95% CI, 4.4-9.3 months) and 19.1 months (95% CI, 15.0-23.3 months), respectively. The ORR and DCR were 32.3% and 60.5%, respectively. The ORR (62.3 vs 22.5%) and DCR (84.9 vs 60.7%) of patients with a CA125 decrease after the first cycle were significantly higher than those without a CA125 decrease (all P < .05). Grade ≥ 3 and serious adverse events were reported in 9.9% and 3.9% of patients, respectively. No treatment-related death was observed. CONCLUSION PLD showed promising efficacy and manageable tolerability in patients with partially platinum-sensitive, platinum-resistant, or platinum-refractory ovarian cancer.ClinicalTrials.gov Identifier: Chinese Clinical Trial Registry, ChiCTR1900022962.

Abstract
MUC16/CA125 is a common diagnostic marker for many types of cancer. However, due to the widespread expression of MUC16 in cancer, its specificity and sensitivity as a target are poor, which severely limits its clinical application. In recent years, various studies have shown that the clinical application potential of MUC16/CA125 has been greatly improved. The update of detection technology improves the accuracy and range of detection, and improves the early diagnosis rate of cancer. Targeting MUC16/CA125 is an important strategy for tumor therapy. Targeting residual amino acids, n-glycoylation structures or other targets on the surface of MUC16 cells can greatly improve the accuracy of detection and therapy. The new drug delivery method broke through the original technical shackles, targeted MUC16 positive cells more specifically and improved the drug efficacy. In this paper, the technological advances in detecting and identifying MUC16 targets and the great progress in cancer screening and treatment based on MUC16 as a target are described in detail, revealing the great potential of MUC16 as a target in cancer screening and treatment, and illustrating the potential clinical application value of MUC16.

Abstract
The HOX gene family encodes for regulatory transcription factors that play a crucial role in embryogenesis and differentiation of adult cells. This highly conserved family of genes consists of thirty-nine genes in humans that are located in four clusters, A-D, on different chromosomes. While early studies on the HOX gene family have been focused on embryonic development and its related disorders, research has shifted to examine aberrant expression of HOX genes and the subsequent implication in cancer prediction and progression. Due to their role of encoding master regulatory transcription factors, the abnormal expression of HOX genes has been shown to affect all stages of tumorigenesis and metastasis. This review highlights the novel role of the HOX family's clinical relevance as both prognostic and diagnostic biomarkers in hematological and solid tumors.

Abstract
Genomic analysis has played a significant role in the identification of driver mutations that are linked to disease progression and response to drug treatment in ovarian cancer. A prominent example is the stratification of epithelial ovarian cancer (EOC) patients with homologous recombination deficiency (HRD) characterized by mutations in DNA damage repair genes such as BRCA1/2 for treatment with PARP inhibitors. However, recent studies have shown that some epithelial ovarian tumors respond to PARP inhibitors irrespective of their HRD or BRCA mutation status. An exclusive focus on the genome overlooks the significant insight that can be gained from other biological analytes, including proteins, which carry out cellular functions. Proteogenomics is the integration of genomics, transcriptomics, epigenomics and proteomics data. This review paper provides novel insight into the role of proteogenomics as an analytical approach to identify predictive biomarkers of drug treatment response in epithelial ovarian cancer. Proteogenomic analysis can facilitate the identification of predictive biomarkers of drug treatment response, consequently greatly improving the stratification of patients with EOC for treatment towards a goal of personalized medicine.

Abstract
Extracellular vesicles (EVs), crucial mediators in cell-to-cell communication, are implicated in both homeostatic and pathological processes. Their detectability in easily accessible peripheral fluids like saliva positions them as promising candidates for non-invasive biomarker discovery. However, the lack of standardized methods for salivary EVs isolation greatly limits our ability to study them. Therefore, we rigorously compared salivary EVs isolated using two scalable techniques-co-precipitation and immuno-affinity-against the long-established but labor-intensive ultracentrifugation method. Employing Cryo-Electron Microscopy (Cryo-EM), Nanoparticle Tracking Analysis, Western blots (WB), and proteomics, we identified significant method-dependent variances in the size, concentration, and protein content of EVs. Importantly, our study uniquely demonstrates the ability of EV isolation to detect specific biomarkers that remain undetected in whole saliva by WB. RT-qPCR analysis targeting six miRNAs confirmed a consistent enrichment of these miRNAs in EV-derived cargo across all three isolation methods. We also found that pre-filtering saliva samples with 0.22 or 0.45 µm pores adversely affects subsequent analyses. Our findings highlight the untapped potential of salivary EVs in diagnostics and advocate for the co-precipitation method as an efficient, cost-effective, and clinically relevant approach for small-volume saliva samples. This work not only sheds light on a neglected source of EVs but also paves the way for their application in routine clinical diagnostics.

Abstract
This study explores the application of serum biomarkers in the diagnosis of adenomatous polyps and evaluates the effectiveness of different markers and their combined diagnosis in adenomatous polyp detection. Using receiver operating characteristic curve analysis, this study assessed the efficacy of serum biomarkers such as carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), alpha-fetoprotein (AFP), carbohydrate antigen 199 (CA199), and prothrombin time (PT) in diagnosing adenomatous polyps in 90 patients. The study also compared the diagnostic accuracy of individual tests versus combined diagnostic approaches and analyzed the impact of polyp size and number on the levels of these markers. Among the individual tests, CA125 showed relatively high diagnostic efficacy. However, combined diagnostic approaches, such as the combination of CEA and CA125, the trio of CEA, CA125, and AFP, and the quartet of CEA, CA125, AFP, and PT, significantly improved diagnostic sensitivity and specificity. Additionally, the study found that the size and number of adenomatous polyps significantly influenced the levels of CEA, CA125, CA199, and PT, with larger and more numerous polyps associated with higher marker levels. This study demonstrates that combined diagnostic strategies have significant advantages in diagnosing adenomatous polyps, providing more accurate and comprehensive diagnostic information. Furthermore, the impact of polyp size and number on serum biomarker levels suggests that these clinical factors should be considered in clinical assessments. These findings offer new perspectives and approaches for the diagnosis of adenomatous polyps.

Single-Cell RNA Sequencing of PBMCs Identified Junction Plakoglobin (JUP) as Stratification Biomarker for Endometriosis. Int J Mol Sci 2024; 25:13071. [PMID: 39684780 DOI: 10.3390/ijms252313071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2024] [Revised: 11/29/2024] [Accepted: 11/29/2024] [Indexed: 12/18/2024] Open
Abstract
This study aimed to identify unique characteristics in the peripheral blood mononuclear cells (PBMCs) of endometriosis patients and develop a non-invasive early diagnostic tool. Using single-cell RNA sequencing (scRNA-seq), we constructed the first single-cell atlas of PBMCs from endometriosis patients based on 107,964 cells and 25,847 genes. Within CD16+ monocytes, we discovered JUP as a dysregulated gene. To assess its diagnostic potential, we measured peritoneal fluid (PF) and serum JUP levels in a large cohort of 199 patients including 20 women with ovarian cancer (OC). JUP was barely detectable in PF but was significantly elevated in the serum of patients with endometriosis and OC, with levels 1.33 and 2.34 times higher than controls, respectively. Additionally, JUP was found in conditioned culture media of CD14+/CD16+ monocytes aligning with our scRNA-seq data. Serum JUP levels correlated with endometriosis severity and endometrioma presence but were unaffected by dysmenorrhea, menstrual cycle, or adenomyosis. When combined with CA125 (cancer antigen 125) JUP enhanced the specificity of endometriosis diagnosis from 89.13% (CA125 measured alone) to 100%. While sensitivity remains a challenge at 19%, our results suggest that JUP's potential to enhance diagnostic accuracy warrants additional investigation. Furthermore, employing serum JUP as a stratification marker unlocked the potential to identify additional endometriosis-related genes, offering novel insights into disease pathogenesis.

[PMID: 38517321 DOI: 10.1002/jmri.29359] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 03/11/2024] [Accepted: 03/11/2024] [Indexed: 03/23/2024] Open
Abstract
BACKGROUND It remains unclear whether extracting peritumoral volume (PTV) radiomics features are useful tools for evaluating response to chemotherapy of epithelial ovarian cancer (EOC). PURPOSE To evaluate MRI radiomics signatures (RS) capturing subtle changes of PTV and their added evaluation performance to whole tumor volume (WTV) for response to chemotherapy in patients with EOC. STUDY TYPE Retrospective. POPULATION 219 patients aged from 15 to 79 years were enrolled. FIELD STRENGTH/SEQUENCE 3.0 or 1.5T, axial fat-suppressed T2-weighted imaging (FS-T2WI), diffusion-weighted imaging (DWI), and contrast enhanced T1-weighted imaging (CE-T1WI). ASSESSMENT MRI features were extracted from the four axial sequences and six different volumes of interest (VOIs) (WTV and WTV + PTV (WPTV)) with different peritumor sizes (PS) ranging from 1 to 5 mm. Those features underwent preprocessing, and the most informative features were selected using minimum redundancy maximum relevance and least absolute shrinkage and selection operator to construct the RS. The optimal RS, with the highest area under the curve (AUC) of receiver operating characteristic was then integrated with independent clinical characteristics through multivariable logistic regression to construct the radiomics-clinical model (RCM). STATISTICAL TESTS Mann-Whitney U test, chi-squared test, DeLong test, log-rank test. P < 0.05 indicated a significant difference. RESULTS All the RSs constructed on WPTV exhibited higher AUCs (0.720-0.756) than WTV (0.671). Of which, RS with PS = 2 mm displayed a significantly better performance (AUC = 0.756). International Federation of Gynecology and Obstetrics (FIGO) stage was identified as the exclusive independent clinical evaluation characteristic, and the RCM demonstrated higher AUC (0.790) than the RS, but without statistical significance (P = 0.261). DATA CONCLUSION The radiomics features extracted from PTV could increase the efficiency of WTV radiomics for evaluating the chemotherapy response of EOC. The cut-off of 2 mm PTV was a reasonable value to obtain effective evaluation efficiency. LEVEL OF EVIDENCE 4 TECHNICAL EFFICACY: Stage 2.

Abstract
Ovarian cancer is one of the predominant gynecologic malignancies worldwide, ranking as the fifth leading cause of cancer-induced mortality among women globally. Post-translational modifications (PTMs) refer to the enzyme-catalyzed attachment of functional groups to proteins, thereby inducing structural and functional alterations. Recent evidence suggests that PTMs play multifaceted roles in the pathogenesis of ovarian cancer, influencing processes such as cell cycle, metabolism reprogramming, chemoresistance, and immune responses against cancer. Accordingly, a comprehensive understanding of the diverse PTMs in ovarian cancer is imperative for decoding the complex molecular mechanisms that drive cancer progression. This review discusses the latest developments in the study of protein PTMs in ovarian cancer and introduces pharmacological approaches that target these modifications as therapeutic strategies.

Abstract
Pyruvate dehydrogenase kinase 1 (PDK1) is a new therapeutic target that is dysregulated in multiple tumors. This study aims to explore the potential role and regulatory mechanism of PDK1 in epithelial ovarian cancer (EOC). We detect PDK1 expression in EOC tissues and cells using qRT-PCR and western blot analysis, and the effects of PDK1 on EOC cell malignant behaviors are explored. RNA sequencing analyses are performed to explore the differentially expressed genes in PDK1-silenced EOC cells. Furthermore, tumor-bearing mouse models are established to assess the impacts of PDK1 and BGN on EOC tumor growth and metastasis in vivo. The results show that PDK1 is upregulated in EOC tissues and cell lines. Biglycan (BGN) is downregulated in PDK1-silenced EOC cells, and its expression is positively correlated with PDK1 levels in EOC tissues. PDK1 depletion inhibits EOC cell proliferation, migration and invasion. Mechanistically, PDK1 and BGN are colocalized in the cytoplasm of EOC cells and interact with each other. PDK1 positively regulates BGN expression by enhancing BGN mRNA stability. BGN overexpression partially reverses the anti-tumor effects of PDK1 depletion on EOC cell malignant behaviors. PDK1 has also been revealed to upregulate BGN to activate the NF-κB oncogenic pathway in EOC cells. Additionally, PDK1 accelerates tumor growth and metastasis by modulating BGN expression. In conclusion, PDK1 functions as an oncogene, facilitating EOC progression by upregulating BGN and activating the NF-κB pathway. These findings may provide valuable biomarkers for the diagnosis and treatment of EOC.

Zhou M, Tang J, Huang G, Hong L. Prognostic Significance and Immune Landscape of a Cuproptosis-Related LncRNA Signature in Ovarian Cancer. Biomedicines 2024; 12:2640. [PMID: 39595204 PMCID: PMC11592286 DOI: 10.3390/biomedicines12112640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2024] [Revised: 11/15/2024] [Accepted: 11/17/2024] [Indexed: 11/28/2024] Open
Abstract
Background: Cuproptosis is a copper-induced mitochondrial cell death, and regulating cuproptosis is becoming a rising cancer treatment modality. Here, we attempted to establish a cuproptosis-associated lncRNAs (CRLs) signature (CRlncSig) to predict the survival, immune landscape, and treatment response in ovarian cancer (OC) patients. Methods: A series of statistical analyses were used to identify the key CRLs that are closely related to the prognosis, and a prognostic CRlncSig was constructed. The predictive accuracy of the CRlncSig was further validated in an independent Gene Expression Omnibus (GEO) set. Then, we compared the immune cell infiltration, immune checkpoints, tumor microenvironment (TME), tumor mutational burden (TMB), drug sensitivity, and efficacy of immunotherapy between the two subgroups. We further built a nomogram integrating the CRlncSig and different clinical traits to enhance the clinical application of the CRlncSig. Results: Nine hub CRLs, namely RGMB-AS1, TYMSOS, DANCR, LINC00702, LINC00240, LINC00996, DNM1P35, LINC00892, and TMEM254-AS1, were correlated with the overall survival (OS) of OC and a prognostic CRlncSig was established. The CRlncSig classified OC patients into two risk groups with strikingly different survival probabilities. The time-dependent ROC (tdROC) curves demonstrated good predictive ability in both the training cohort and an independent validation cohort. Multivariate analysis confirmed the independent predictive performance of the CRlncSig. We constructed a nomogram based on the CRlncSig, which can predict the prognosis of OC patients. The high-risk score was characterized by decreased immune cell infiltration and activation of stroma, while activation of immunity was observed in the low-risk subgroup. Moreover, patients in low-risk subgroups had more Immunophenoscore (IPS) and fewer immune escapes compared to high-risk subgroups. Finally, an immunotherapeutic cohort confirmed the value of the CRlncSig in predicting immunotherapy outcomes. Conclusions: The developed CRlncSig may be promising for the clinical prediction of OC patient outcomes and immunotherapeutic responses.

Abstract
Background As a prevalent malignancy in women, ovarian cancer (OC) presents a challenge in clinical practice because of its poor prognosis and poor therapeutic efficacy. The mechanism by which cuproptosis activity is accompanied by immune infiltration in OC remains unknown. Here, we investigated cuproptosis-related OC subtypes and relevant immune landscapes to develop a risk score (RS) model for survival prediction. Methods Cuproptosis-related genes (CRGs) were identified to construct molecular subtypes via an unsupervised clustering algorithm based on the expression profiles of survival-related CRGs in the GEO database. Single-cell datasets were used to estimate immune infiltration among subtypes. The RS oriented from molecular subtypes was developed via LASSO Cox regression in the TCGA OC dataset and independently validated in the GEO and TCGA datasets. Hub markers from RS were identified in tissues and cell lines. The function of the key gene from RS was identified in vitro. Results We investigated cuproptosis activity and immune infiltration to establish three clinical subtypes of OC based the differentially expressed genes (DEGs) from CRGs to create an RS model validated for clinical efficacy and prognosis. Six hub genes from the RS served as ongenic markers in OC tissues and cell lines. The function of GAS1 in the RS model revealed that it exerts oncogenic effects. Conclusions Our study provides a novel RS model including 6 hub genes associated with cuproptosis and immune infiltration to predict OC prognosis as well as clinical efficacy.

Abstract
Background Late diagnosis and patient relapse, mainly due to chemoresistance, are the key reasons for the high mortality rate of ovarian cancer patients. Hence, the search for biomarkers of high predictive value within the phenomenon of chemoresistance is vital. This study performs a bibliometric analysis of the scientific literature concerning biomarkers of drug resistance in ovarian cancer, considering the period from 2017 to 2022. Methods The terms "drug resistance biomarker" and "ovarian cancer" were linked by the Boolean operator "AND". The search was done in PubMed, selecting documents published over the last 5 years (2017-2022), which were analyzed with the open-source tool Bibliometrix developed in the R package. The language of the publications was restricted to English. Several types of papers such as case reports, clinical trials, comparative studies, and original articles were considered. Results A total of 335 scientific articles were analyzed. The United States and China were the leading contributors and established the largest number of scientific collaborations. The Huazhong University of Science and Technology and the University of Texas MD Anderson Cancer Center were the most influential institutions. The Journal of Ovarian Research, International Journal of Molecular Science, and Scientific Reports are among the most relevant journals. The study identified high-profile, relevant thematic niches and important descriptors that indicate topics of interest, including studies on women, cell lines, solid tumors, and gene expression regulation. As well as studies involving middle-aged and adult participants, and those focusing on prognosis evaluation. Descriptors such as "drug resistance," "neoplasm," "genetics," "biomarker," "gene expression profile," and "drug therapy" would indicate new research trends. In addition, we propose that BCL-2, CHRF, SNAIL, miR-363, iASPP, ALDH1, Fzd7, and EZH2 are potential biomarkers of drug resistance. Conclusions This paper contributes to the global analysis of the scientific investigation related to drug resistance biomarkers in ovarian cancer to facilitate further studies and collaborative networks, which may lead to future improvements in therapy for this lethal disease.

Abstract
Epithelial ovarian cancer (EOC) is the most lethal gynecological malignancy worldwide. Due to its nonspecific symptoms and unreliable screening tools, EOC is not diagnosed at an early stage in most cases. Unfortunately, despite achieving initial remission after debulking surgery and platinum-based chemotherapy, most patients experience the recurrence of the disease. The limited therapy approaches have encouraged scientists to search for new detection and therapeutic strategies. In this review, we discuss the role of folate receptor alpha (FRα) in EOC development and its potential application as a biomarker and molecular target in designing new EOC screening and treatment methods. We summarize the mechanisms of the action of various therapeutic strategies based on FRα, including MABs (monoclonal antibodies), ADCs (antibody-drug conjugates), FDCs (folate-drug conjugates), SMDCs (small molecule-drug conjugates), vaccines, and CAR-T (chimeric antigen receptor T) cells, and present the most significant clinical trials of some FRα-based drugs. Furthermore, we discuss the pros and cons of different FR-based therapies, highlighting mirvetuximab soravtansine (MIRV) as the currently most promising EOC-targeting drug.

Abstract
Ovarian cancer (OC), the second leading cause of death among gynecological cancers, is often diagnosed at an advanced stage due to its asymptomatic nature at early stages. This study aimed to explore the diagnostic potential of plasma-based lipidomics combined with machine learning (ML) in OC. Non-targeted lipidomics analysis was conducted on plasma samples from participants with epithelial ovarian cancer (EOC), benign ovarian tumor (BOT), and healthy control (HC). The samples were randomly divided into a train set and a test set. Differential lipids between groups were selected using two-tailed Student's t-test and partial least squares discriminant analysis (PLS-DA). Both single lipid-based receiver operating characteristic (ROC) model, and multiple lipid-based ML model, were constructed to investigate the diagnostic value of the differential lipids. The results showed several lipids with significant diagnostic potential. ST 27:2;O achieved the highest prediction accuracy of 0.92 in distinguishing EOC from HC. DG 42:2 had the highest prediction accuracy of 0.96 in diagnosing BOT from HC. Cer d18:1/18:0 had the highest prediction accuracy of 0.65 in differentiating EOC from BOT. Furthermore, multiple lipid-based ML models illustrated better diagnostic performance. K-nearest neighbors (k-NN), partial least squares (PLS), and random forest (RF) models achieved the highest prediction accuracy of 0.96 in discriminating EOC from HC. The support vector machine (SVM) model reached the highest prediction accuracy both in distinguishing BOT from HC, and in differentiating EOC from BOT, with accuracies of 1.00 and 0.74, respectively. In conclusion, this study revealed that the combination of plasma-based lipidomics and ML algorithms is an effective method for diagnosing OC.

Abstract
Cancer, a life-threatening genetic disease caused by abnormalities in normal cell growth regulatory functions, poses a significant challenge that current medical technologies cannot fully overcome. The current desired breakthrough is to diagnose cancer as early as possible and increase survival rates through treatments tailored to the prognosis and appropriate follow-up. From a perspective that reflects this contemporary paradigm of cancer diagnostics, exosomes are emerging as promising biomarkers. Exosomes, serving as mobile biological information repositories of cancer cells, have been known to create a microtumor environment in surrounding cells, and significant insight into the clinical significance of cancer diagnosis targeting them has been reported. Therefore, there are growing interests in constructing a system that enables continuous screening with a focus on patient-friendly and flexible diagnosis, aiming to improve cancer screening rates through exosome detection. This review focuses on a proposed exosome-embedded biological information-detecting platform employing a field-effect transistor (FET)-based biosensor that leverages portability, cost-effectiveness, and rapidity to minimize the stages of sacrifice attributable to cancer. The FET-applied biosensing technique, stemming from variations in an electric field, is considered an early detection system, offering high sensitivity and a prompt response frequency for the qualitative and quantitative analysis of biomolecules. Hence, an in-depth discussion was conducted on the understanding of various exosome-based cancer biomarkers and the clinical significance of recent studies on FET-based biosensors applying them.

J Minim Invasive Gynecol 2024; 31:919-928. [PMID: 39004184 DOI: 10.1016/j.jmig.2024.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 07/06/2024] [Accepted: 07/08/2024] [Indexed: 07/16/2024]
Abstract
OBJECTIVE To compare oncologic outcomes after laparoscopic or laparotomic surgery to treat epithelial ovarian carcinoma in FIGO Stage I. DESIGN Retrospective cohort study. SETTING Gynecological cancer ward in a tertiary hospital. PARTICIPANTS A total of 85 patients with FIGO Stage I epithelial ovarian carcinoma who underwent laparoscopic staging surgery and 206 who underwent laparotomic staging surgery at West China Second Hospital, Sichuan University (Chengdu, China) between January 1, 2013 and December 31, 2019. INTERVENTIONS Laparoscopic surgery or laparotomic staging surgery. RESULTS Before propensity score-based matching, the laparotomy group showed higher prevalence of preoperative elevated CA125 level (48.5% vs 35.3%, p = .045) and tumors >15 cm (27.2% vs 5.9%, p <.001). Multivariate analysis associated higher body mass index with better overall survival (adjusted HR 0.83, 95% CI 0.70-0.99, p = .043). Among propensity score-matched patients (82 per group) who were matched to each other according to propensity scoring based on age, body mass index, CA125 level, largest tumor diameter, FIGO stage, history of abdominal surgery, and American Society of Anesthesiologists grade, the rate of progression-free survival at 5 years was similar between the laparoscopy group (87.1%, 95% CI 79.3-95.7%) and the laparotomy group (90.9%, 95% CI 84.7-97.6%, p = .524), as was the rate of overall survival at 5 years (93.9%, 95% CI 88.0-100.0% vs 94.7%, 95% CI 89.8-99.9%, p = .900). Regardless of whether patients were matched, the two groups showed similar rates of recurrence of 9-11% during follow-up lasting a median of 54.9 months. CONCLUSIONS Rates of recurrence and survival may be similar between laparoscopy or laparotomy to treat Stage I epithelial ovarian cancer. Since laparoscopy is associated with less bleeding and faster recovery, it may be a safe, effective alternative to laparotomy for appropriate patients.

Abstract
Metastasis-promoting Lewis and sialyl Lewis antigens expressed on glycoproteins such as mucins are frequently displayed on the surface of prostate cancer cells and could thus be ideal candidates as measures of prostate cancer aggressiveness. The current study describes the altered expression of sialyl Lewisa (sLea) antigen attached to glycoproteins and key glycosyltransferases between normal prostate (RWPE-1) and cancerous cell lines (LNCaP and DU145). Our results suggest that the expression of sLea on different glycoproteins correlates with the aggressiveness of prostate cancer cells, as determined by flow cytometry and fluorescence microscopy. Blotting studies revealed that sLea-bearing glycoproteins, similar to mucins, are predominantly expressed in the more aggressive DU145 cells, followed by LNCaP cells. Immunohistochemistry technique showed a gradient of sLea expression, with low levels in low-grade prostate cancer (stage II/III) and increasing levels in high-grade cancer (stage IV), indicating its potential as a prognostic marker. Additionally, in qRT-PCR analysis significant upregulation of the glycosyltransferases GALNT5 and ST3GAL6 was observed, correlating with the increased sLea expression in LNCaP (3.2- and 14.5-fold) and DU145 (3.3- and 23.75-fold) cells. Our data indicates a correlation between sLea selectin ligand expression and prostate cancer aggressiveness. Furthermore, GALNT5 and ST3GAL6 could serve as benchmarks in PCa malignancy.

[PMID: 39438390 DOI: 10.1007/s10528-024-10939-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Accepted: 10/06/2024] [Indexed: 10/25/2024]
Abstract
Cisplatin (DDP) resistance is one of the causes of treatment failure for ovarian cancer (OV). Mitochondrial cholesterol level was reported to be associated with OV chemoresistance. We found that ABCA10, a potential cholesterol transport protein, was highly expressed in ovarian tissues and downregulated in OV tissues. Our study aimed to explore TCF21/ABCA10 axis resistance to DDP therapy in ovarian cancer based on regulating mitochondrial cholesterol efflux. Thirty epithelial ovarian cancer tumors and thirty ovarian tissues from non-cancer patients were collected. Western blot and RT-qPCR were used to measure ABCA10 and TCF21 expression levels in these tissues, as well as in a human ovarian epithelial cell line (IOSE-80), OV cells (A2780 and SKOV3), and DDP-resistant OV cell lines (A2780/DDP and SKOV3/DDP). IOSE-80 cells were also infected with ABCA10 knockdown lentivirus to identify the most effective ABCA10 knockdown plasmid. Lentiviral infection was used to create ABCA10 knockdown, ABCA10 overexpression, and TCF21 overexpression anti-DDP OV cell lines. Cell proliferation was detected by CCK-8 and EDU staining, flow cytometry for apoptosis, MTT for metabolic activity, calcium-induced Cytochrome C release, and mitochondrial matrix swelling for mitochondrial function and Oil Red O staining for lipid accumulation. Cholesterol metabolism was evaluated by measuring mitochondrial cholesterol and cholesterol efflux. Protein concentration was determined using the BCA method. A dual-luciferase reporter assay confirmed TCF21's interaction with ABCA10. ChIP also verified this interaction. The mRNA level (P < 0.01) and protein level (P < 0.001) of ABCA10 were downregulated in cancer tissues of OV patients relative to normal ovarian tissues. Relative to human ovarian epithelial cells, ABCA10 expression was significantly downregulated in OV cells (P < 0.01) and even more significantly downregulated in DDP-resistant OV cells (P < 0.001). Compared to the group treated solely with DDP, the overexpression of ABCA10 significantly inhibited the proliferation of DDP-resistant OV cells (P < 0.01), markedly reduced the staining intensity of EDU in these cells (P < 0.05), and substantially accelerated apoptosis in DDP-resistant OV cells (P < 0.01).Overexpression of ABCA10 further accelerated Cytochrome C expression and mitochondrial matrix swelling in DDP-resistant OV cells compared to the DDP-alone group (P < 0.01). The addition of cholesterol reversed the decrease in lipid accumulation, the decrease in mitochondrial cholesterol levels (P < 0.05), and the increase in cholesterol efflux (P < 0.01) in DDP-resistant OV cells caused by overexpression of ABCA10. The transcription factor TCF21 was bound to the promoter of ABCA10. Overexpression of TCF21 significantly increased ABCA10 expression in DDP-resistant OV cells (P < 0.01) and increased cytochrome C expression in A2780/DDP (P < 0.05) and SKOV3/DDP (P < 0.01) cells, with accelerated mitochondrial matrix swelling in A2780/DDP (P < 0.01) and SKOV3/DDP (P < 0.001) cells, while knockdown of ABCA10 reversed these effects. Our study found that TCF21 boosts ABCA10 expression, which in turn reduces DDP resistance in OV cells by enhancing mitochondrial cholesterol efflux. This mechanism increases the sensitivity of DDP-resistant OV cells to DDP. Our findings will provide new therapeutic targets for the treatment of ovarian cancer.

Abstract
Background Recurrence is the main factor for poor prognosis in ovarian cancer, but few prognostic biomarkers were reported. In this study, we used machine learning methods based on multiple biomarkers to develop a specific prediction model for the recurrence of ovarian cancer. Methods A total of 277 ovarian cancer patients were enrolled in this study and randomly classified into training and testing cohorts. The prediction information was obtained through 47 clinical parameters using six supervised clustering machine learning algorithms, including K-Nearest Neighbor (K-NN), Decision Tree (DT), Random Forest (RF), Adaptive Boosting (AdaBoost), Gradient Boosting Machine (GBM), and Extreme Gradient Boosting (XGBoost). Results In predicting the recurrence of ovarian cancer, machine learning algorithm was superior to conventional logistic regression analysis. In this study, XGBoost showed the best performance in predicting the recurrence of ovarian cancer, with an accuracy of 0.95. In addition, neoadjuvant chemotherapy, Monocyte ratio (MONO%), Hematocrit (HCT), Prealbumin (PAB), Aspartate aminotransferase (AST), and carbohydrate antigen 125 (CA125) are the most important biomarkers to predict the recurrence of ovarian cancer. Conclusion The machine learning techniques can achieve a more accurate assessment of the recurrence of ovarian cancer, which can help clinicians make decisions, and develop personalized treatment strategies.

Abstract
BACKGROUND Personalized medicine remains an unmet need in ovarian cancer due to its heterogeneous nature and complex immune microenvironments, which has gained increasing attention in the era of immunotherapy. A key obstacle is the lack of reliable biomarkers to identify patients who would benefit significantly from the therapy. While conventional clinicopathological factors have exhibited limited efficacy as prognostic indicators in ovarian cancer, multi-omics profiling presents a promising avenue for comprehending the interplay between the tumor and immune components. Here we aimed to leverage the individual proteomic and transcriptomic profiles of ovarian cancer patients to develop an effective protein-based signature capable of prognostication and distinguishing responses to immunotherapy. METHODS The workflow was demonstrated based on the Reverse Phase Protein Array (RPPA) and RNA-sequencing profiles of ovarian cancer patients from The Cancer Genome Atlas (TCGA). The algorithm began by clustering patients using immune-related gene sets, which allowed us to identify immune-related proteins of interest. Next, a multi-stage process involving LASSO and Cox regression was employed to distill a prognostic signature encompassing five immune-related proteins. Based on the signature, we subsequently calculated the risk score for each patient and evaluated its prognostic performance by comparing this model with conventional clinicopathological characteristics. RESULTS We developed and validated a protein-based prognostic signature in a cohort of 377 ovarian cancer patients. The risk signature outperformed conventional clinicopathological factors, such as age, grade, stage, microsatellite instability (MSI), and homologous recombination deficiency (HRD) status, in terms of prognoses. Patients in the high-risk group had significantly unfavorable overall survival (p < 0.001). Moreover, our signature effectively stratified patients into subgroups with distinct immune landscapes. The high-risk group exhibited higher levels of CD8 T-cell infiltration and a potentially greater proportion of immunotherapy responders. The co-activation of the TGF-β pathway and cancer-associated fibroblasts could impair the ability of cytotoxic T cells to eliminate cancer cells, leading to poor outcomes in the high-risk group. CONCLUSIONS The protein-based signature not only aids in evaluating the prognosis but also provides valuable insights into the tumor immune microenvironments in ovarian cancer. Together our findings highlight the importance of a thorough understanding of the immunosuppressive tumor microenvironment in ovarian cancer to guide the development of more effective immunotherapies.

Abstract
Epithelial ovarian cancer (EOC) presents considerable difficulties in prognostication and treatment strategy development. Bevacizumab, an anti-angiogenic medication, has demonstrated potential in enhancing progression-free survival (PFS) in EOC patients. Nevertheless, the identification of individuals at elevated risk of disease progression following treatment remains a challenging task. This study was to develop and validate a deep learning (DL) model using retrospectively collected computed tomography (CT) plain scans of inoperable and recurrent EOC patients receiving bevacizumab treatment diagnosed between January 2013 and January 2024. A total of 525 patients from three different institutions were retrospectively included in the study and divided into training set (N = 400), internal test set (N = 97) and external test set (N = 28). The model's performance was evaluated using Harrell's C-index. Patients were categorized into high-risk and low-risk group based on a predetermined cutoff in the training set. Additionally, a multimodal model was evaluated, incorporating the risk score generated by the DL model and the pretreatment level of carbohydrate antigen 125 as input variables. The Net Reclassification Improvement (NRI) metric quantified the reclassification performance of our optimal model in comparison to the International Federation of Gynecology and Obstetrics (FIGO) staging model. The results indicated that DL model achieved a PFS predictive C-index of 0.73 in the internal test set and a C-index of 0.61 in the external test set, along with hazard ratios of 34.24 in the training set (95% CI: 21.7, 54.1; P < 0.001) and 8.16 in the internal test set (95% CI: 2.5, 26.8; P < 0.001). The multimodal model demonstrated a C-index of 0.76 in the internal test set and a C-index of 0.64 in the external test set. Comparative analysis against FIGO staging revealed an NRI of 0.06 (P < 0.001) for the multimodal model. The model presents opportunities for prognostic assessment, treatment strategizing, and ongoing patient monitoring.

Abstract
Time series is a data structure prevalent in a wide range of fields such as healthcare, finance and meteorology. It goes without saying that analyzing time series data holds the key to gaining insight into our day-to-day observations. Among the vast spectrum of time series analysis, time series classification offers the unique opportunity to classify the sequences into their respective categories for the sake of automated detection. To this end, two types of mainstream approaches, recurrent neural networks and distance-based methods, have been commonly employed to address this specific problem. Despite their enormous success, methods like Long Short-Term Memory networks typically require high computational resources. It is largely as a consequence of the nature of backpropagation, driving the search for some backpropagation-free alternatives. Reservoir computing is an instance of recurrent neural networks that is known for its efficiency in processing time series sequences. Therefore, in this article, we will develop two reservoir computing based methods that can effectively deal with regular and irregular time series with minimal computational cost, both while achieving a desirable level of classification accuracy.
