Early screening of lung nodules is mainly done manually by reading the patient's lung CT. This approach is time-consuming laborious and prone to leakage and misdiagnosis. Current methods for lung nodule detection face limitations such as the high cost of obtaining large-scale, high-quality annotated datasets and poor robustness when dealing with data of varying quality. The challenges include accurately detecting small and irregular nodules, as well as ensuring model generalization across different data sources. Therefore, this paper proposes a lung nodule detection model based on semi-supervised learning and knowledge distillation (SSLKD-UNet). In this paper, a feature encoder with a hybrid architecture of CNN and Transformer is designed to fully extract the features of lung nodule images, and at the same time, a distillation training strategy is designed in this paper, which uses the teacher model to instruct the student model to learn the more relevant features to nodule regions in the CT images and, and finally, this paper applies the rough annotation of the lung nodules to the LUNA16 and LC183 dataset with the help of semi-supervised learning idea, and completes the model with the accurate annotation of lung nodules. Combined with the accurate lung nodule annotation to complete the model training process. Further experiments show that the model proposed in this paper can utilize a small amount of inexpensive and easy-to-obtain coarse-grained annotations of pulmonary nodules for training under the guidance of semi-supervised learning and knowledge distillation training strategies, which means inaccurate annotations or incomplete information annotations, e.g., using nodule coordinates instead of pixel-level segmentation masks, and realize the early recognition of lung nodules. The segmentation results further corroborates the model's efficacy, with SSLKD-UNet demonstrating superior delineation of lung nodules, even in cases with complex anatomical structures and varying nodule sizes.

The combination of radiotherapy and immunotherapy exerts synergistic antitumor in a range of human cancers, and also in esophageal cancer. Radiotherapy-induced tumor immune microenvironment (TIME) reprogramming is an essential basis for the synergistic antitumor between radiotherapy and immunotherapy. Radiotherapy can induce autophagy in tumor cells and immune cells of TIME, and autophagy activation is involved in the modification of immunological characteristics of TIME. The TIME landscape of esophageal cancer, especially ESCC, can be affected by radiotherapy or autophagy regulation. In this review, we depicted that local radiotherapy-induced autophagy could promote the maturation, migration, infiltration, and function of immune cells by complicated mechanisms to make TIME from immune "cold" to "hot", resulting in the synergistic antitumor of RT and IO. We argue that unraveling the relevance of radiotherapy-initiated autophagy to driving radiotherapy reprogramming TIME will open new ideas to explore new targets or more efficiently multimodal therapeutic interventions in ESCC.

Postoperative pulmonary infections (POPIs) occur in approximately 13-38% of patients who undergo surgery for esophageal cancer, negatively impacting patient outcomes and prolonging hospital stays. This study aims to develop a novel clinical prediction model to identify patients at risk for POPIs early, thereby enabling timely intervention by clinicians.

This study included 910 patients from two hospitals. Of these, 795 patients from one hospital were randomly assigned to the training cohort (n = 556) and the validation cohort (n = 239) at a 7:3 ratio. The external test cohort consisted of 115 patients from the second hospital. A nomogram was developed via logistic regression to predict the incidence of POPIs. The model's discrimination, precision and clinical benefit were evaluated by constructing a receiver operating characteristic (ROC) curve, calculating the area under the ROC curve (AUC), performing a calibration plot, conducting decision curve analysis (DCA) and clinical impact curves (CIC).

Multivariate logistic regression revealed that age, anemia, neoadjuvant therapy, T stage, thoracic adhesions and duration of surgery were independent risk factors for POPIs. The AUC for the training cohort was 0.8095 (95% CI: 0.7664-0.8527), that for the validation cohort was 0.8039 (95% CI: 0.7436-0.8643), and that for the external test cohort was 0.7174 (95% CI: 0.6145-0.8204). Calibration plots demonstrated good agreement between the predicted and observed probabilities, while DCA and CIC demonstrated good clinical applicability of the model in three cohorts.

The nomogram, which incorporates six key factors, effectively predicts the risk of POPIs and can serve as a valuable tool for clinicians in identifying high-risk patients.

The ORIENT-15 double-blind randomized controlled trial demonstrated that the addition of sintilimab to chemotherapy for locally advanced or metastatic oesophageal squamous cell carcinoma (OSCC) resulted in better clinical outcomes. In this analysis, we sought to evaluate the cost-effectiveness of sintilimab as a first-line treatment for locally advanced or metastatic OSCC from a healthcare system perspective in China.

A partitioned survival model was constructed to perform a cost-effectiveness analysis comparing chemotherapy alone with sintilimab for locally advanced or metastatic OSCC patients. Clinical data were obtained from the ORIENT-15 trial and extrapolated to 10 years. Health state utilities and costs were sourced from the literature and from public healthcare institutions. The primary outcomes included the incremental cost-effectiveness ratio (ICER) and quality-adjusted life-years (QALYs). Two different sensitivity analyses, one-way and probabilistic, were performed to assess model uncertainty.

Sintilimab-based chemotherapy was more costly ($31699.21 vs. $20687.42) and more effective (0.74 vs. 0.53) than placebo-based chemotherapy, resulting in an ICER of $51908.19 /QALY, which is greater than the willingness-to-pay (WTP) threshold of China ($38223/QALY). Sensitivity analysis demonstrated that the PFS and cost of sintilimab were the major influencing factors affecting the results.

In patients with locally advanced or metastatic OSCC, sintilimab chemotherapy could improve survival time and health benefits compared with traditional chemotherapy, but the present analysis suggests that sintilimab is not a cost-effective treatment option in China.

Hypoxia is a typical hallmark of solid tumors and plays a crucial role in the progression of esophageal squamous cell carcinogenesis (ESCC). Nevertheless, the precise mechanisms underlying the involvement of hypoxia in tumor development remain unclear. In the present study, a novel hypoxia-induced long noncoding RNA (lncRNA) is identified first, lnc191, which is highly expressed in clinical ESCC tissues and is positively correlated with poor prognosis of ESCC patients. These findings provide evidence that the hypoxia-inducible factor-1α (HIF-1α)-mediated transcriptional activation of lnc191 enhances the growth and metastasis of ESCC cells both in vitro and in vivo. Mechanistically, lnc191 interacts with GRP78 (78-kDa glucose-regulated protein), one of the endoplasmic reticulum chaperone proteins, leading to its translocation to the membrane, where GRP78 binds with EGFR and enhances its phosphorylation (Y845), further activates ERK/MAPK signaling pathway, and thereby in favor of the progression of ESCC. Overall, this data proposes lnc191 as a key driver during the development of ESCC and reveals the participation of the activated GRP78/ERK/MAPK axis in the ESCC progression mediated by lnc191. These findings indicate the potential of lnc191 as a promising diagnostic biomarker and therapeutic target in ESCC.

To investigate the relationship between the abundance of CD4+ and CD8+ T cells in the tumor microenvironment and the prognosis of patients with esophageal squamous cell carcinoma, and to analyze their correlation and explore its clinical value.

In total, we enrolled 120 cases of esophageal squamous cell carcinoma diagnosed. The abundance of CD4+ and CD8+ T lymphocytes in the tissue specimens of esophageal cancer was examined by immunohistochemistry. We measured the correlation between the abundance of CD4+ and CD8+ T lymphocytes and the clinical and pathological characteristics and prognosis of esophageal squamous cell carcinoma.

The tissue abundance of CD4+ T lymphocytes was closely related to tumor prognosis ( P < 0.05). Similarly, there was a statistically significant relationship between the tissue abundance of CD8+ T lymphocytes and patients' prognosis ( P < 0.05), indicating that a high abundance of CD8+ T lymphocytes predicts better prognosis in esophageal squamous cell carcinoma. Surprisingly, we found that a higher CD4+/CD8+ ratio predicted a better prognosis of esophageal squamous cell carcinoma.

The tissue abundance of CD4+ and CD8+ T lymphocytes can serve as an important indicator for predicting the long-term survival of patients with esophageal squamous cell carcinoma. A high CD4+/CD8+ ratio may improve patients' prognosis through several pathways. The association of this ratio with clinical and pathological characteristics may explain the poor efficacy of immunotherapy in patients with esophageal cancer. These findings may help us find new targets for immunotherapy by exploring the immune microenvironment of esophageal squamous cell carcinoma.

The global incidence of esophageal cancer (EC) remains high. Despite advancements in medical technology and deeper research into the causes and treatment methods of EC, the effectiveness of treatment for EC is still unsatisfactory. Therefore, it is crucial to address the urgent problem of improving the long-term survival rate of EC patients and providing personalized treatment.

To analyze the survival prognosis and influencing factors of esophageal squamous cell carcinoma (ESCC).

A retrospective analysis was conducted on the clinical data of 115 patients with pT3N0M0 ESCC who underwent radical surgery alone from January 1, 2013, to December 31, 2019. The Kaplan-Meier method was used to evaluate the 1-year, 3-year, and 5-year survival rates and median survival time of the patients. The Cox proportional hazards regression model was used to assess the hazard ratios (HRs) and 95% confidence intervals (95%CIs) of risk factors.

The 1-year, 3-year, and 5-year overall survival (OS) rates for the 115 EC patients analyzed were 85.22%, 50.43%, and 37.48%, respectively. The median OS was 37.00 (95%CI: 24.93-49.07) months, and the median disease-free survival was 21.00 (95%CI: 14.71-27.29) months. Both univariate and multivariate Cox regression analyses revealed that high body mass index (BMI; HR = 1.137, 95%CI: 1.054-1.226), positive perineural invasion (PNI; HR = 13.381, 95%CI: 4.899-36.547), and smoking (HR = 2.415, 95%CI: 1.388-4.203) were independent risk factors for a poor prognosis. In contrast, compared to the upper thoracic location of the tumor, middle thoracic (HR = 0.441, 95%CI: 0.240-0.810) and lower thoracic (HR = 0.328, 95%CI: 0.144-0.750) locations were protective factors.

BMI, tumor location, PNI, and smoking are associated with the prognosis of ESCC patients. This study highlights the prognostic risk factors for T3N0M0 ESCC patients and offers personalized insights for clinical treatment.

Radioresistance is a major obstacle for the therapy of esophageal squamous cell carcinoma (ESCC) and lead to a poor prognosis. Ferroptosis is supposed to be responsible for radioresistance. However, the ferroptosis-induced radioresistance in ESCC and its related regulatory mechanisms are not yet fully understood. In this study, human ESCC cell line and the corresponding radioresistance cells were irradiated with 6 megavolts (MV) X-ray. It was showed that irradiation led to less ferroptosis in radioresistant ESCC cells as compared to the parental cells, as depicted by transmission electron microscopy, intracellular Fe2+ iron contents, lipid peroxidation, and expression of COX2. The increase of ASCL4 expression levels in radioresistant cells after radiotherapy was smaller than that in the parental cells. ACSL4 overexpression significantly enhanced ferroptosis. The fold increase in ACSL4 m6A modification in the radioresistant cells was significantly smaller than that in the parental cells as detected by methylated RNA immunoprecipitation with qRT-PCR. METTL14 overexpression accelerated ferroptosis induced by irradiation via upregulating m6A modification of ACSL4 mRNA. In conclusions, ferroptosis ablation was responsible for the radioresistant of ESCC. The METTL14-mediated m6A modification of ACSL4 mRNA sensitized ESCC to irradiation via accelerating ferroptosis. This study sheds new light on our understanding of radioresistant in ESCC, and provides potential strategies for ESCC radiotherapy.

To evaluate the benefits of volumetric modulated arc therapy (VMAT) based on multicriteria optimization (MCO) for gastric cancer patients, particularly the protection of serial organs at risk (OARs) that overlap with the target volume.

MCO and single-criterion optimization (SCO) VMAT plans were conducted among 30 gastric cancer patients, with a prescription dose of 50.4 Gy delivered in 28 fractions. All treatment plans underwent review, and a comparison was made between the active planning time and different dose-volume parameters.

Both the MCO and SCO VMAT plans achieved the target dose coverage, with no significant difference in the conformity index (CI) for the planning target volume (PTV), at median CI values of 0.887 and 0.891, respectively (P = 0.417). The MCO plans showed a slight but significant increase in the homogeneity index of the PTV, with a median increase of 0.029 (P < 0.001). Additionally, the MCO plans resulted in a lower D2% to the small intestine and duodenum, with reductions of 3.43 Gy and 0.3 Gy, respectively (P < 0.05). Furthermore, the Dmax to the small intestine correlated moderately with the overlapping volume between the small intestine and the target volume (ρ = 0.42, P = 0.023). Except for the mean dose to the liver, the MCO plans performed better in terms of dose indicators for other OARs. Moreover, compared to the SCO plans, the median active planning time in the MCO plans was significantly reduced by 53.2 min (P < 0.0001).

MCO can effectively help the physicians to quickly select an optimal treatment plan for patients with gastric cancer. It has been shown that MCO VMAT plans can significantly reduce the dose to OARs and shorten the active planning time, with acceptable target coverage. In addition, these plans take less dosimetric time, thereby streamlining the treatment planning process.

Establishing surrogate endpoints for overall survival (OS) may expedite assessment of new therapies in esophageal cancer (EC) and gastroesophageal junction cancer (GEJC). This study aimed to evaluate disease-free survival (DFS) as a surrogate endpoint for OS.

Patients from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database aged ≥66 years with resection after primary diagnosis of stage 2 or 3 EC/GEJC between 2009 and 2017 were analyzed (N = 925; median follow-up 26.2 months). Surrogacy was assessed by evaluating individual level associations between DFS and OS using Spearman's rank correlation and the association between treatment effects by Pearson's correlation coefficient. To evaluate the association between treatment effects, patients were classified in synthetic clusters based on treatments received. Propensity score matching addressed imbalances in baseline characteristics between treatment and control groups in the clusters. Predictive performance of the surrogacy equation was assessed internally for the generated clusters via leave-one-out cross-validation and externally via predictions for 26 clinical trials of early-stage EC/GEJC.

Patients were mostly male (84%), non-Hispanic white (89.3%), with median age 71.8 years, and cancer stages 2 (50.4%) and 3 (49.6%). Cancer types were adenocarcinoma (76.1%), squamous cell carcinoma (10.4%), and other types (13.5%). Most patients 766/925 (82.8%) received neoadjuvant therapy (680/766 chemoradiotherapy versus 86/766 chemotherapy alone) while 23.6% of the patients received adjuvant therapy. Within each treatment setting, most [705/766 (92.0%) of neoadjuvant therapy and 178/218 (81.7%) of adjuvant therapy] received multi-agent chemotherapy. The individual level correlation was 0.76 (95% confidence interval 0.70-0.80). The correlation between treatment effects was 0.96 (95% confidence interval 0.80-0.99) with a corresponding surrogate threshold effect of 0.71. Both internal (91%) and external (89%) validation of the model demonstrated high predictive accuracy.

Correlations between DFS and OS were meaningful at both individual and treatment effect level. The derived surrogacy equation enables reliable early assessments of OS benefit from the observed DFS benefit for early-stage EC/GEJC treatments in real-world settings.

Family hardiness is a key variable contributing to positive family functioning, which has significant effects on the quality of life and the mental health of patientsand caregivers. The factors that contribute to family hardiness support both the psychological and physical well-being of caregivers is unknown. More specifically, the relationship of family hardiness with attachment and caregiver preparedness has not been explored.

The current study aimed to investigate the family hardiness in caregivers of breast cancer patients and explore the relationship with attachment and caregiver preparedness and identify the associated factors.

This cross-sectional correlational study was conducted from March to July, 2022. 140 caregivers of breast cancer patients were recruited in two IIIA-grade hospitals in Hunan Province using convenience sampling. Data were collected using a personal characteristics questionnaire, The Family Hardiness Index (FHI), Caregiver Preparedness Scale (CPS), and the Experiences in Close Relationships Inventory-Revised Edition (ECR-R). Chi-square, Pearson's correlation coefficient, generalized additive model and multiple logistic regression analyses were performed.

A total of 140 caregivers participated in the study. The mean age of participants was (42.29 ± 14.54) years and most of them were male (57.1%). The mean FHI score of caregivers was 58.11 ± 5.67. Multiple linear regression analysis indicated that family hardiness is affected by ECR-R, CPS, education level, and knowledge of breast cancer. The score of CPS was positively associated with family hardiness (β = 0.265, p < 0.001), whereas ECR-R negatively predicted family hardiness (β = -0.078, p < 0.001).

Family hardiness plays a critical role in helping caregivers manage the stresses associated with providing care to breast cancer patients. Enhancing caregiver preparedness and education, as well as addressing attachment-related issues, can significantly improve family hardiness. In light of our findings, we suggest that closer relationships within families, adding preparedness and knowledge of disease should be encouraged during the care of breast cancer patients.

Gallbladder carcinoma is the most common malignant tumor of the biliary system, and has a poor overall prognosis. Poor prognosis in patients with gallbladder carcinoma is associated with the aggressive nature of the tumor, subtle clinical symptoms, ineffective adjuvant treatment, and lack of reliable biomarkers.

Therefore, evaluating the prognostic factors of patients with gallbladder carcinoma can help improve diagnostic and treatment methods, allowing for tailored therapies that could benefit patient survival.

This article systematically reviews the factors affecting the prognosis of gallbladder carcinoma, with the aim of evaluating prognostic risk in patients.

A comprehensive and in-depth understanding of prognostic indicators affecting patient survival is helpful for assessing patient survival risk and formulating personalized treatment plans.

This study aims to delineate the long-term outcomes and recurrence patterns of locally advanced thoracic esophageal squamous cell carcinoma (TESCC) patients managed with or without postoperative radiotherapy (PORT).

A retrospective cohort from two academic centers, encompassing patients who initially underwent esophagectomy and were pathologically staged T3-4, was analyzed. Survival outcomes were constructed using Kaplan-Meier method, with survival significance was evaluated using the log-rank test. Propensity score matching (PSM) was utilized to balance potential selection bias.

Among the 506 patients, 251 underwent surgery alone and 255 received radiotherapy following radical surgery. With a median follow-up of 49.1 months, PORT significantly improved 5-year overall survival (53.8% vs. 25.3%; p < 0.001) and 5-year disease-free survival rates (45.3% vs. 8.5%; p < 0.001) compared to surgery alone. These differences in survival outcomes persisted even after PSM (p < 0.001 for both). Treatment failure was significantly less frequent in the PORT group (46.7%) compared to the surgery-only group (90.0%; p < 0.001), with corresponding reductions in locoregional recurrence (9.4% vs. 54.1%; p < 0.001). This underscores the significant association between PORT and disease control.

The absence of neoadjuvant chemoradiotherapy highlights the importance of PORT in improving survival and reducing recurrence in advanced T3-4 TESCC patients. This study underscores the importance of PORT as a salvage treatment for locally advanced TESCC patients without neoadjuvant chemoradiotherapy.

The incidence of prostate, breast, and thyroid cancers has increased in China over the past few decades. Whether and how much these increases can be attributed to overdiagnosis are less understood. This study aimed to estimate the proportion of overdiagnosis among these three cancers in China during 2004-2019. The age-specific cancer incidence, cancer mortality, and all-cause mortality in China were extracted from the Global Burden of Diseases 2019. The lifetime risk of developing and that of dying from each cancer were calculated using the life table method. The proportion of overdiagnosis of a cancer was estimated as the difference between the lifetime risk of developing the cancer and that of suffering from the cancer (including death, metastasis, and symptoms caused by the cancer), further divided by the lifetime risk of developing the cancer. The highest possible values of these parameters were adopted in the estimation so as to obtain the lower bounds of the proportions of overdiagnosis. Sensitivity analyses assuming different lag periods between the diagnosis of a cancer and death from the cancer were performed. The results showed that the lifetime risk of developing prostate, breast, and thyroid cancer increased dramatically from 2004 to 2019 in China, while the increase in the lifetime risk of dying from these cancers was less pronounced. The proportions of overdiagnosis among prostate, breast, and thyroid cancers were estimated to be 7.88%, 18.99%, and 24.92%, respectively, in 2004, and increased to 18.20%, 26.25%, and 29.24%, respectively, in 2019. The increasing trends were statistically significant for all three cancers (all p < 0.001). In sensitivity analyses, the proportions of overdiagnosis decreased, but upward trends over time remained for all three cancers. In conclusion, the overdiagnosis of prostate, breast, and thyroid cancers in China increased from 2004 to 2019, with the highest proportion seen in thyroid cancer and the most rapid increase seen in prostate cancer. Multifaceted efforts by policy makers, guideline developers, and clinicians are needed to tackle this problem.

Humans can be exposed to multiple pollutants in the air and surface water. These environments are non-static, trans-boundary and correlated, creating a complex network, and significant challenges for research on environmental hazards, especially in real-world cancer research. This article reports on a large study (377 million people in 30 provinces of China) that evaluated the combined impact of air and surface water pollution on cancer. We formulate a spatial evaluation system and a common grading scale for co-pollution measurement, and validate assumptions that air and surface water environments are spatially connected and that cancers of different types tend to cluster in areas where these environments are poorer. We observe "dose-response" relationships in both the number of affected cancer types and the cancer incidence with an increase in degree of co-pollution. We estimate that 62,847 (7.4%) new cases of cancer registered in China in 2016 were attributable to air and surface water pollution, and the majority (69.7%) of these excess cases occurred in areas with the highest level of co-pollution. The findings clearly show that the environment cannot be considered as a set of separate entities. They also support the development of policies for cooperative environmental governance and disease prevention.

Liver cancer, classified as a malignant hepatic tumor, can be divided into two categories: primary, originating within the liver, and secondary, resulting from metastasis to the liver from other organs. Hepatocellular carcinoma (HCC) is the main form of primary liver cancer and the third leading cause of cancer-related deaths. The diagnosis and prognosis of HCC using current methods still face numerous challenges. This study aims to develop novel diagnostic and prognostic models while identifying new biomarkers for improved HCC treatment. Diagnostic and prognostic models for HCC were constructed using traditional binary classification methods and machine learning algorithms based on the TCGA database (Downloaded in August 2023). The mechanisms by which APLN (Apelin) affects HCC were investigated using single-cell sequencing data sourced from the GEO database (GSE149614). The diagnostic models yielded by various algorithms could effectively distinguished HCC samples from normal ones. The prognostic model, composed of four genes, was constructed using LASSO and Cox regression algorithms, demonstrating good performance in predicting the three-year survival rate of HCC patients. The HCC biomarker Apelin (APLN) was identified in this study. APLN in liver cancer tissues mainly comes from endothelial cells and is associated with the carcinogenesis of these cells. APLN expression is significantly upregulated in liver cancer tissues, marking it as a viable indicator of endothelial cell malignancy in HCC. Furthermore, APLN expression was determined to be an independent predictor of tumor endothelial cell carcinogenesis, unaffected by its modifications such as single nucleotide variation, copy number variation, and methylation. Additionally, liver cancers characterized by high APLN expression are likely to progress rapidly after T2 stage. Our study presents diagnostic and prognostic models for HCC with appreciably improved accuracy and reliability compared to previous reports. APLN is a reliable HCC biomarker and contributes to the establishment of our models.

A milestone goal of the Healthy China Program (2019-2030) is to achieve 5-year cancer survival at 43.3% for all cancers combined by 2022. To assess the progress towards this target, we analyzed the updated survival for all cancers combined and 25 specific cancer types in China from 2019 to 2021.

We conducted standardized data collection and quality control for cancer registries across 32 provincial-level regions in China, and included 6,410,940 newly diagnosed cancer patients from 281 cancer registries during 2008-2019, with follow-up data on vital status available until December 2021. We estimated the age-standardized 5-year relative survival overall and by site, age group, and period of diagnosis using the International Cancer Survival Standard Weights, and quantified the survival changes to assess the progress in cancer control.

In 2019-2021, the age-standardized 5-year relative survival for all cancers combined was 43.7% (95% confidence interval [CI], 43.6-43.7). The 5-year relative survival varied by cancer type, ranging from 8.5% (95% CI, 8.2-8.7) for pancreatic cancer to 92.9% (95% CI, 92.4-93.3) for thyroid cancer. Eight cancers had 5-year survival of over 60%, including cancers of the thyroid, breast, testis, bladder, prostate, kidney, uterus, and cervix. The 5-year relative survival was generally lower in males than in females. From 2008 to 2021, we observed significant survival improvements for cancers of the lung, prostate, bone, uterus, breast, cervix, nasopharynx, larynx, and bladder. The most significant improvement was in lung cancer.

Progress in cancer control was evident in China. This highlights the importance of a comprehensive approach to control and prevent cancer.

CDT1, a gene that shows excessive expression in various malignancies, functions as a pivotal regulator of replication licensing. In this study, we observed a positive correlation in expression between CDT1 and E2F2 among patients with lung adenocarcinoma (LUAD). Our findings substantiated that E2F2 directly interacted with the promoter region of CDT1, as confirmed by ChIP-qPCR assays, and depletion of E2F2 resulted in a downregulation of CDT1 expression in LUAD cell lines by gene interference technology. Furthermore, we identified an upregulation of CDT1 mRNA level in Chinese LUAD samples. Notably, in the loss-of-function assays, depletion of CDT1 in LUAD cell lines inhibited cell proliferation, migration, and invasion. Concurrently, it promoted cell apoptosis and induced G0/G1 phase arrest using MTT, flow cytometry, and Transwell assays, reinforcing its role as an oncogene.Furthermore, enhanced tumor ablation was determined in a CDT1-downregulated LUAD tumor-bearing nude mouse model. Collectively, our results strongly suggest that E2F2 positively regulates CDT1 expression and actively participates in the progression of lung adenocarcinoma, thereby providing valuable insights into identifying novel therapeutic targets for LUAD treatment.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. Its high recurrence rate and lack of effective control drugs result in a 5-year survival rate of only about 10%. HCC is a tumor regulated by the immune system. Significant breakthroughs have occurred in treating solid tumors with immunotherapy in recent years. Various immunotherapies, such as immune checkpoint inhibitors (ICIs), including combination therapies, have demonstrated promising therapeutic effects in both clinical applications and research. Other immunotherapies, such as adoptive cell therapies and oncolytic viruses, are also emerging, offering hope for addressing long-term survival issues in HCC. This article reviews current commonly used immunotherapy strategies and the latest research findings for reference.

Endometrial cancer is considered to be the second most common tumor of the female reproductive system, and patients diagnosed with advanced endometrial cancer have a poor prognosis. The influence of fatty acid metabolism in the prognosis of patients with endometrial cancer remains unclear. We constructed a prognostic risk model using transcriptome sequencing data of endometrial cancer and clinical information of patients from The Cancer Genome Atlas (TCGA) database via least absolute shrinkage and selection operator regression analysis. The tumor immune microenvironment was analyzed using the CIBERSORT algorithm, followed by functional analysis and immunotherapy efficacy prediction by gene set variation analysis. The role of model genes in regulating endometrial cancer in vitro was verified by CCK-8, colony formation, wound healing, and transabdominal invasion assays, and verified in vivo by subcutaneous tumor transplantation in nude mice. A prognostic model containing 14 genes was constructed and validated in 3 cohorts and clinical samples. The results showed differences in the infiltration of immune cells between the high-risk and low-risk groups, and that the high-risk group may respond better to immunotherapy. Experiments in vitro confirmed that knockdown of epoxide hydrolase 2 (EPHX2) and acyl-CoA oxidase like (ACOXL) had an inhibitory effect on EC cells, as did overexpression of hematopoietic prostaglandin D synthase (HPGDS). The same results were obtained in experiments in vivo. Prognostic models related to fatty acid metabolism can be used for the risk assessment of endometrial cancer patients. Experiments in vitro and in vivo confirmed that the key genes HPGDS, EPHX2, and ACOXL in the prognostic model may affect the development of endometrial cancer.

The alteration of the immune microenvironment in the axillary metastatic lymph nodes of luminal A breast cancer patients is still unclear.

Postsurgical tissues from the enrolled luminal A BCs were divided into five categories: primary BC lesion at stage N0 (PL1), primary BC lesion at stage N1 (PL2), negative axillary lymph node at stage N0 BC (LN1), negative axillary lymph node at stage N1 BC (LN2), and positive axillary lymph node at stage N1 BC (LN3). The frequencies of positive immune markers (CD4, CD8, PD1, PD-L1, T-cell immunoglobulin and mucin domain 3 (TIM3), and forkhead box protein 3 (Foxp3)) in the above tissues were quantified by AKOYA Opal Polaris 7 Color Manual IHC Detection Kit.

A total of 50 female patients with luminal A BC were enrolled in this study. Among these patients, 23 had stage N1 disease, and 27 had stage N0 disease. Compared with that in the PL2 subgroup, the frequency of PD-1-positive cells was significantly greater in the PL1 subgroup, whether at the stromal or intratumoral level (P value < 0.05). Both the frequency of CD8 + T cells in LN1 and that in LN2 were significantly greater than that in LN3 (P value < 0.05). The frequency of TIM3 + T cells in LN1 was significantly greater than that in PL1 (P value < 0.05). The frequency of CD8 + TIM3 + T cells was significantly greater in both the LN2 and LN3 groups than in the PL2 group (P value < 0.05). The frequency of CD4 + Foxp3 + T cells was significantly greater in LN1 than in PL1 (P value < 0.05), which was the same for both LN3 and PL2 (P value < 0.05).

Increased frequencies of CD8 + PD1+, CD8 + TIM3 + and CD4 + Foxp3 + T cells might inhibit the immune microenvironment of axillary metastatic lymph nodes in luminal A breast cancer patients and subsequently promote lymph node metastasis.

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer. Metformin has been shown to have the potential to inhibit the proliferation of malignant cells. This study aimed to investigate the regulatory effect of metformin on the expression of programmed death protein ligand 1(PD-L1) and mechanisms in TNBC.

Mouse breast cancer cell line 4T1 was co-cultured with metformin, and the effect of metformin on cell proliferation was detected by MTT assay. The effect of metformin on the expression of JNK, RSK2 and CREB was detected by MAPK pathway protein chip. BALB/c mice were inoculated with 4T1 cells with knockdown/overexpression of C-Jun N-terminal kinase (JNK), and administered with metformin. The weight of tumor tissue was observed at the end of the experiment. The expression of PD-L1 in tumor cells was observed by immunofluorescence staining and the level of INF-γwas quantitatively determined by ELISA.

Metformin inhibited the viability of 4T1 cells and increased the phosphorylation of JNK to reduce the phosphorylation of RSK2 and CREB. Metformin and JNK knockdown reduced the expression of PD-L1 in tumor cells, but there was no significant difference in the weight of tumor tissue. Metformin can reduce the level of INF-γ in tumor tissues, but JNK has no effect.

Metformin can inhibit the expression of PD-L1 in triple-negative breast cancer mice and improve the tumor microenvironment, but does not reduce the size of the tumor.

The long non-coding RNA X-inactive specific transcript (XIST) plays a crucial role in transcriptional silencing of the X chromosome. Zinc finger E-box-binding homeobox 1 (ZEB1) is a transcription factor involved in epithelial-mesenchymal transition (EMT) regulation.

This study aimed to investigate the impact of XIST on esophageal squamous cell carcinoma (ESCC) progression and its underlying mechanism involving the miR-34a/ZEB1/E-cadherin/EMT pathway.

XIST and ZEB1 expression were analyzed using quantitative PCR and immunohistochemistry. XIST knockdown was achieved in KYSE150 ESCC cells using siRNA or shRNA lentivirus transfection. Proliferation, migration, and invasion abilities were assessed, and luciferase reporter assays were performed to confirm XIST-miR-34a-ZEB1 interactions. In vivo ESCC growth was evaluated using a xenograft mouse model.

XIST and ZEB1 were upregulated in tumor tissues, correlating with metastasis and reduced survival. XIST knockdown inhibited proliferation, migration, and invasion of KYSE150 cells. It decreased ZEB1 expression, increased E-cadherin and miR-34a levels. Luciferase reporter assays confirmed miR-34a binding to XIST and ZEB1. XIST knockdown suppressed xenograft tumor growth.

XIST promotes ESCC progression via the miR-34a/ZEB1/E-cadherin/EMT pathway. Targeting the XIST/miR-34a/ZEB1 axis holds therapeutic potential and serves as a prognostic biomarker in ESCC.

Cancer-related fatigue (CRF) is considered one of the most prevalent and distressing symptoms among cancer patients and may vary among patients with different cancer types. However, few studies have explored the influence of physical and psychological symptoms on CRF among esophageal cancer (EC) patients without esophagectomy. Therefore, this study aimed to examine the effects of physical and psychological symptoms on CRF among EC patients without esophagectomy.

In the present study, a cross-sectional study was conducted from February 2021 to March 2022 in Liaoning Province, China. Among the 112 included participants, 97 completed our investigation. The questionnaires used consisted of the Brief Fatigue Inventory (BFI), the MD Anderson Symptom Inventory Gastrointestinal Cancer Module (MDASI-GI), the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7), and demographic and clinical information. Multivariate linear regression was conducted to test the relationships between physical and psychological symptoms and CRF.

Of the 97 EC patients, 60.8% reported CRF (BFI ≥ 4). The mean age of the participants was 64.92 years (SD = 8.67). According to the regression model, all the variables explained 74.5% of the variance in CRF. Regression analysis indicated that physical symptoms, including constipation, diarrhoea, and difficulty swallowing, contributed to CRF. On the other hand, depressive symptoms increased the level of CRF among EC patients without esophagectomy.

Given the high prevalence of CRF among EC patients without esophagectomy, it is urgent to emphasize the importance of fatigue management interventions based on physical and psychological symptoms to alleviate CRF in EC patients.

The oncogenic role of circRNA in cancers including esophageal cancer (EC) has been well studied. However, whether and how circRNAs are involved in cancer cell metabolic processes remains largely unknown. Here, we reported that circRNA, circHIPK3, is highly expressed in ESCC cell lines and tissues. Knockdown of circHIPK3 significantly restrained cell proliferation, colony formation, migration, and invasion in vitro and inhibited tumor growth in vivo. Mechanistically, circHIPK3 was found to act as a ceRNA by sponging miR-637 to regulate FASN expression and fatty acid metabolism in ESCC cells. Anti-sense oligonucleotide (ASO) targeting circHIPK3 substantially inhibited ESCC both in vitro and in vivo. Therefore, these results uncover a modulatory axis constituting of circHIPK3/miR-637/FASN may be a potential biomarker and therapeutic target for ESCC in the clinic.

Ovarian cancer is the most lethal gynecological malignancy. Timely diagnosis of ovarian cancer is difficult due to the lack of effective biomarkers. Laboratory tests are widely applied in clinical practice, and some have shown diagnostic and prognostic relevance to ovarian cancer. We aimed to systematically evaluate the value of routine laboratory tests on the prediction of ovarian cancer, and develop a robust and generalisable ensemble artificial intelligence (AI) model to assist in identifying patients with ovarian cancer.

In this multicentre, retrospective cohort study, we collected 98 laboratory tests and clinical features of women with or without ovarian cancer admitted to three hospitals in China during Jan 1, 2012 and April 4, 2021. A multi-criteria decision making-based classification fusion (MCF) risk prediction framework was used to make a model that combined estimations from 20 AI classification models to reach an integrated prediction tool developed for ovarian cancer diagnosis. It was evaluated on an internal validation set (3007 individuals) and two external validation sets (5641 and 2344 individuals). The primary outcome was the prediction accuracy of the model in identifying ovarian cancer.

Based on 52 features (51 laboratory tests and age), the MCF achieved an area under the receiver-operating characteristic curve (AUC) of 0·949 (95% CI 0·948-0·950) in the internal validation set, and AUCs of 0·882 (0·880-0·885) and 0·884 (0·882-0·887) in the two external validation sets. The model showed higher AUC and sensitivity compared with CA125 and HE4 in identifying ovarian cancer, especially in patients with early-stage ovarian cancer. The MCF also yielded acceptable prediction accuracy with the exclusion of highly ranked laboratory tests that indicate ovarian cancer, such as CA125 and other tumour markers, and outperformed state-of-the-art models in ovarian cancer prediction. The MCF was wrapped as an ovarian cancer prediction tool, and made publicly available to provide estimated probability of ovarian cancer with input laboratory test values.

The MCF model consistently achieved satisfactory performance in ovarian cancer prediction when using laboratory tests from the three validation sets. This model offers a low-cost, easily accessible, and accurate diagnostic tool for ovarian cancer. The included laboratory tests, not only CA125 which was the highest ranked laboratory test in importance of diagnostic assistance, contributed to the characterisation of patients with ovarian cancer.

This study aims to analyze how changes in pathological diagnosis practice and molecular detection technology have affected clinical outcomes for colorectal cancer (CRC) patients in Fudan University Shanghai Cancer Center (FUSCC).

This retrospective cohort study analyzed 21,141 pathologically confirmed CRC cases diagnosed at FUSCC from 2008 to 2020. Patients were divided into five groups for different analytical purposes: (1) the before vs. since 2014 groups to analyze the influence of the changes in the classification criteria of pT3 and pT4 staging on the survival of patients; (2) the partial vs. total mesorectal excision (TME) groups to analyze whether evaluation of completeness of the mesorectum have impact on the survival of patients; (3) the tumor deposit (TD)(+)N0 vs. TD(+)N1c groups to analyze the influence of the changes in the pN staging on the survival of patients with positive TD and negative regional lymph node metastasis (LNM); (4) the before vs. since 2013 groups to analyze the influence of the changes in the testing process of deficient mismatch repair on the survival of patients; and (5) the groups with vs. without RAS/BRAF gene mutation testing to analyze the influence of these testing on the survival of patients. Patients' clinicopathological parameters, including age at diagnosis, sex, tumor size, location, differentiation, mucinous subtype, TD, lymphovascular invasion, perineural invasion, tumor depth, LNM and distant metastasis, and tumor-node-metastasis (TNM) stage, were compared between groups. Kaplan-Meier analysis with log rank method was performed for patients' overall survival (OS) and disease-free survival (DFS) analyses.

In pathological reports, there were three parameter changes that impacted patient outcomes. Firstly, changes in the pT staging criteria led to a shift of the ratio of patients with stage pT3 to stage pT4 from 1: 110.9 to 1: 0.26. In comparison to patients admitted before 2014 (n = 4,754), a significant difference in prognosis between pT3 and pT4 stages was observed since 2014 (n = 9,965). Secondly, we began to evaluate the completeness of the mesorectum since 2016. As a result, 91.0% of patients with low rectal cancer underwent TME (n = 4,111) surgery, and patients with TME had significantly better OS compared with partial mesorectal excision (PME, n = 409). Thirdly, we began to stage TD (+) LNM (-) as N1c since 2017. The results showed that N1c (n = 127) but not N0 (n = 39) can improve the prognosis of patients without LNM and distal metastasis. In molecular testing, there have been three and five iterations of updates regarding mismatch repair (MMR)/microsatellite instability (MSI) status and RAS/BRAF gene mutation detection, respectively. The standardization of MMR status testing has sharply decreased the proportion of deficient MMR (dMMR) patients (from 32.5% to 7.4%) since 2013. The prognosis of patients underwent MMR status testing since 2013 (n = 867) were significantly better than patients before 2013 (n = 1,313). In addition, detection of RAS/BRAF gene mutation status (n = 5,041) resulted in better DFS but not OS, for patients with stage I-III disease (n = 16,557).

Over the past few decades, updates in elements in pathological reports, as well as the development of standardized tests for MMR/MSI status and RAS/BRAF gene mutations have significantly improved patient outcomes.

This is a comprehensive overview of long-term cancer survival in Zhejiang Province, China. Hybrid analysis, a combination of cohort and period analysis, has been proposed to derive up-to-date cancer survival estimates. Using this approach, we aimed to timely and accurately analyze the 5-year relative survival (RS) and net survival (NS) in cancer registries of Zhejiang Province, China.

A total of 255,725 new cancer cases diagnosed during 2013-2017 were included in 14 cancer registries in Zhejiang Province, China, with a follow-up on vital status until the end of 2019. The hybrid analysis was used to calculate the 5-year RS and 5-year NS during 2018-2019 for overall and stratifications by sex, cancer type, region, and age at diagnosis.

During 2018-2019, the age-standardized 5-year RS and NS for overall cancer in Zhejiang was 47.5% and 48.6%, respectively. The age-standardized 5-year RS for cancers of women (55.4%) was higher than that of men (40.0%), and the rate of urban areas (49.7%) was higher than that of rural areas (43.1%). The 5-year RS declined along with age, from 84.4% for ages <45 years to 23.7% for ages >74 years. Our results of the RS and NS showed the similar trend and no significant difference. The top five cancers with top age-standardized 5-year RS were thyroid cancer (96.0%), breast cancer (84.3%), testicular cancer (79.9%), prostate cancer (77.2%), and bladder cancer (70.6%), and the five cancers with the lowest age-standardized 5-year RS were pancreatic cancer (6.0%), liver cancer (15.6%), gallbladder cancer (17.1%), esophageal cancer (22.7%), and leukemia (31.0%).

We reported the most up-to-date 5-year cancer RS and NS in Zhejiang Province, China for the first time, and found that the 5-year survival for cancer patients in Zhejiang during 2018-2019 was relatively high. The population-based cancer registries are recognized as key policy tools that can be used to evaluate both the impact of cancer prevention strategies and the effectiveness of health systems.

To look into the relationship between cardiac substructures (CS) dosimetric parameters and cardiac events (CE) or overall survival (OS) in patients undergoing radiation therapy (RT) for esophageal squamous cell carcinoma (ESCC).

A retrospective study included 350 patients with ESCC receiving definitive chemoradiotherapy or radiotherapy (d-CRT/d-RT) or neoadjuvant chemoradiotherapy (NCRT) from March 2013 to May 2022. Our study examined the adverse cardiac events of any grade or G3+, as defined by the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Competing risk analysis and Cox regression analysis were used to assess the relationship between CS doses and CEs or OS.

201 (57.4 %) patients received any grade CEs over a median follow-up time of 22.50 months (IQR, 12.40-45.60), and 24 (6.86 %) patients suffered G3+ CEs. On landmark analysis, patients with any grade CEs had significantly lower OS (P = 0.003). Multivariable analysis revealed that any grade CEs were predicted by the dose of CSs in all populations. In addition, for G3+ cardiac events, arrhythmic and small probability of cardiac events, LAD V20 ((HR: 1.02, 95 % CI: 1.00-1.03, P = 0.012; HR: 1.01, 95 % CI: 1.00-1.02, P = 0.005; HR; 1.01, 95 % CI: 1.00-1.02, P = 0.012) was also an independent predictive factor. LAD V50 (HR: 1.07, 95 % CI: 1.03-1.10, P <0.001) predicted pericardium effusion events. Moreover, the multivariable analysis revealed that OS was predicted by LAD V30 (HR: 1.03; 95 % CI, 1.01-1.05, P = 0.015).

In the population of ESCC patients receiving RT, we showed that the CS factors had a substantial predictive value for the various types and grades of CEs. The elevated radiation dose of LAD was a significant contributor to a higher rate of cardiac events and a worse prognosis.

The morbidity and mortality rates in lung cancer are high worldwide. Early diagnosis and personalized treatment are important to manage this public health issue. In recent years, artificial intelligence (AI) has played increasingly important roles in early screening, auxiliary diagnosis, and prognostic assessment. AI uses algorithms to extract quantitative feature information from high-volume and high-latitude data and learn existing data to predict disease outcomes. In this review, we describe the current uses of AI in lung cancer-focused pathomics, imageomics, and genomics applications.

Using the published survival statistics from cancer registration or population-based studies, we aimed to describe the global pattern and trend of lung cancer survival.

By searching SinoMed, PubMed, Web of Science, EMBASE, and SEER, all survival analyses from cancer registration or population-based studies of lung cancer were collected by the end of November 2022. The survival rates were extracted by sex, period, and country. The observed, relative, and net survival rates of lung cancer were applied to describe the pattern and time changes from the late 1990s to the early 21st century.

Age-standardized 5-year relative/net survival rate of lung cancer was typically low, with 10%-20% for most regions. The highest age-standardized relative/net survival rate was observed in Japan (32.9%, 2010-2014), and the lowest was in India (3.7%, 2010-2014). In most countries, the five-year age-standardized relative/net survival rates of lung cancer were higher in females and younger people. The patients with adenocarcinoma had a better prognosis than other groups. In China, the highest 5-year overall relative/net survival rates were 27.90% and 31.62% in men and women in Jiangyin (2012-2013).

Over the past decades, the prognosis of lung cancer has gradually improved, but significant variations were also observed globally. Worldwide, a better prognosis of lung cancer can be observed in females and younger patients. It is essential to compare and evaluate the histological or stage-specific survival rates of lung cancer between different regions in the future.

It's still controversial whether Helicobacter pylori (H. pylori) eradication can reverse atrophic gastritis (AG) and intestinal metaplasia (IM). Therefore, we performed a meta-analysis to estimate the effect of H. pylori eradication on AG and IM.

We searched the PubMed, Web of Science and EMBASE datasets through April 2023 for epidemiological studies, which provided mean glandular atrophy (GA) or IM score before and after H. pylori eradication, or provided ORs, RRs or HRs and 95% CIs for the association of AG or IM with H. pylori eradication. Weighted mean difference (WMD) and pooled ORs and 95%CIs were used to estimate the effect of H. pylori eradication on AG and IM.

Twenty articles with a total of 5242 participants were included in this meta-analysis. H. pylori eradication significantly decreased GA score in the antrum (WMD -0.36; 95% CI: -0.52, -0.19, p < 0.01), GA score in the corpus (WMD -0.35; 95% CI: -0.52, -0.19, p < 0.01), IM score in the antrum (WMD -0.16; 95% CI: -0.26, -0.07, p < 0.01) and IM score in the corpus (WMD -0.20; 95% CI: -0.37, -0.04, p = 0.01). H. pylori eradication significantly improved AG (pooled OR 2.96; 95% CI: 1.70, 5.14, p < 0.01) and IM (pooled OR 2.41; 95% CI: 1.24, 4.70, p < 0.01). The association remained significant in the subgroup analyses by study design, sites of lesions, regions and follow-up time. Although Publication bias was observed for AG, the association remained significant after trim-and-fill adjustment.

H. pylori eradication could significantly improve AG and IM at early stage.

There has been a lot of interest in stem cell therapy as a means of curing disease in recent years. Despite extensive usage of stem cell therapy in the treatment of a wide range of medical diseases, it has been hypothesized that it plays a key part in the progression of cancer. Breast cancer is still the most frequent malignancy in women globally. However, the latest treatments, such as stem cell targeted therapy, are considered to be more effective in preventing recurrence, metastasis, and chemoresistance of breast cancer than older methods like chemotherapy and radiation. This review discusses the characteristics of stem cells and how stem cells may be used to treat breast cancer.

The aberrant expression of serpin family E member 1 (SERPINE1) is associated with carcinogenesis. This study assessed the alteration of SERPINE1 expression for an association with gastric adenocarcinoma prognosis.

The Cancer Genome Atlas (TCGA) dataset was applied to investigate the impact of SERPINE1 expression on the survival of patients afflicted with gastric cancer. Subsequently, 136 samples from the Affiliated Huaian No. 1 People's Hospital of Nanjing Medical University were subjected to qRT-PCR and Western blot to validate the expression level of SERPINE1 between tumor and adjacent normal tissues. The correlation between the expression of SERPINE1 with the clinicopathological features in TCGA patients was analyzed using Wilcoxon signed-rank and logistic regression tests. The potential molecular mechanism associated with SERPINE1 expression in gastric cancer were confirmed using gene set enrichment analysis (GSEA).

The TCGA data showed that SERPINE1 was overexpressed in tumor tissues compared to normal mucosae and associated with the tumor T stage and pathological grade. SERPINE1 overexpression was associated with the poor overall survival (OS) of patients. The findings were confirmed with 136 patients, that is, SERPINE1 expression was associated with poor OS (hazard ratio (HR): 1.82; 95% confidence interval (CI): 0.84-1.83; p = 0.012)) as an independent predictor (HR: 2.11, 95% CI: 0.81-2.34; p = 0.009). The resulting data were further processed by GSEA showed that SERPINE1 overexpression was associated with the activation of EPITHELIAL_MESENCHYMAL_TRANSITION, TNFA_SIGNALING_VIA_NFKB, INFLAMMATORY_RESPONSE, ANGIOGENESIS, and HYPOXIA.

SERPINE1 overexpression is associated with a poor gastric cancer prognosis.

Patient navigation is an effective intervention measure to promote the integration of medical systems and services. By providing individualized, coordinated, and continuous care, patient navigation offers a way to address the problem of fragmented services across institutions and levels of care in the whole-process management of lung cancer, providing assistance to patients with complex healthcare needs. Herein, we reviewed the origin, the development, the models, and the application status of patient navigation in China and other countries. We also analyzed the considerations regarding introducing patient navigation in the whole-process management of lung cancer against the background of medical consortiums in China, discussing why patient navigation should be introduced, how to introduce patient navigation, as well as potential challenges and coping strategies. Patient navigation meets the current needs for equitable, accessible, systematic, continuous, and integrated prevention and treatment services for chronic diseases in the context of the Healthy China Strategy. It helps fill the gaps in the continuity and coordination of whole-process management of lung cancer patients in the context of medical consortiums. However, introducing patient navigation in medical consortiums involving multiple institutions and levels of care may face challenges, including incompatibility between the health information systems of different institutions, poor cross-institutional collaboration and communication, and limited resources. Further improvement is needed in medical informatization, coordination and communication mechanisms, and benefit distribution mechanisms within the medical consortiums. In this paper, we intend to provide insights and suggestions for developing patient navigation models that suit China's local characteristics and for promoting the implementation and development of whole-process management of lung cancer in the context of the medical consortium system.

Overall, thyroid cancer is the most common endocrine malignancy. This cancer is fifth most common cancer among adult women and the second most common cancer in women over 50 years old and it occurs in women 3 times more than men. The present systematic review and meta-analysis were designed with the aim of determining the 5-year survival rate of thyroid cancer in Asian countries in 2022.

The current study is a systematic review and meta-analysis of thyroid cancer survival rates in Asian countries. Researchers in the study searched for articles published in six international databases: PubMed/Medline, EMBASE, Scopus, Google Scholar, ISI (Web of Knowledge), and ProQuest until July 03, 2022. A checklist (The Newcastle-Ottawa Quality Assessment Form) has been prepared in previous studies to evaluate the quality of articles.

In general, 38 articles were entered for the meta-analysis. The 5-year survival rate was 95.3%, with a 95% confidence interval of 93.5% to 96.6%. The year of study is a cause of variability in results of 5-year (Reg Coef = 0.145, P < 0.001). According to the results, an increased survival rate across the study period was observed. Human Development Index was a cause of variability in results of 5-year survival rates (Reg Coef = 12.420, P < 0.001). The results of Table 2 showed that women have 4% more 5-year survival rate than men (Hazard ratio: 1.05 CI: 95% 1.04-1.06)).

In general, the 5-year survival of thyroid cancer in Asian countries was higher than in European countries, but it is at a lower level than in the United States.

China has a high mortality from nasopharyngeal carcinoma (NPC). The NPC mortality trends in China from 2006 to 2020 were described and analyzed to understand its epidemiological characteristics by region and sex and to explore age, period, and cohort effects.

This study utilized NPC mortality data from the China Health Statistical Yearbook. A joinpoint regression model was used to fit the standardized NPC mortality and age-specific mortality. The age-period-cohort model was applied to investigate age, period, and cohort effects on NPC mortality risk.

The results showed that the NPC mortality rate in China has been declining steadily. From 2006 to 2020, the standardized NPC mortality rate in most age groups showed a significant downward trend. The annual percentage change was smaller in rural areas than in urban areas. The mortality risks of rural males and rural females from 2016 to 2020 were 1.139 times and 1.080 times those from 2011 to 2015, respectively. Both urban males born in 1984-1988 and rural males born in 1979-1983 exhibited an increasing trend in NPC mortality risk.

Our study confirmed the effectiveness of NPC prevention and treatment strategies in China from 2006 to 2020. However, it underscored the urgent need for targeted interventions in rural areas to further reduce NPC mortality rates.
