Liver transplantations (LTs) with extended criteria have produced surgical results comparable to those obtained with traditional standards. However, it is not sufficient to predict hepatocellular carcinoma (HCC) recurrence after LT according to morphological criteria alone. The present study aimed to construct a nomogram for predicting HCC recurrence after LT using extended selection criteria.

Retrospective data on patients with HCC, including pathology, serological markers and follow-up data, were collected from January 2015 to April 2020 at Huashan Hospital, Fudan University, Shanghai, China. Logistic least absolute shrinkage and selection operator (LASSO) regression and multivariate Cox regression analyses were performed to identify and construct the prognostic nomogram. Receiver operating characteristic (ROC) curves, Kaplan-Meier curves, decision curve analyses (DCAs), calibration diagrams, net reclassification indices (NRIs) and integrated discrimination improvement (IDI) values were used to assess the prognostic capacity of the nomogram.

A total of 301 patients with HCC who underwent LT were enrolled in the study. The nomogram was constructed, and the ROC curve showed good performance in predicting survival in both the development set (2/3) and the validation set (1/3) (the area under the curve reached 0.748 and 0.716, respectively). According to the median value of the risk score, the patients were categorized into the high- and low-risk groups, which had significantly different recurrence-free survival (RFS) rates (P < 0.01). Compared with the Milan criteria and University of California San Francisco (UCSF) criteria, DCA revealed that the new nomogram model had the best net benefit in predicting 1-, 3- and 5-year RFS. The nomogram performed well for calibration, NRI and IDI improvement.

The nomogram, based on the Milan criteria and serological markers, showed good accuracy in predicting the recurrence of HCC after LT using extended selection criteria.

Hepatocellular carcinoma (HCC) is a prevalent and lethal cancer, often diagnosed at advanced stages where traditional treatments such as surgical resection, liver transplantation, and locoregional therapies provide limited benefits. Hepatic arterial infusion chemotherapy (HAIC) has emerged as a promising treatment modality for advanced HCC, enhancing anti-tumor efficacy through targeted drug delivery while minimizing systemic side effects. However, the heterogeneous nature of HCC leads to variable responses to HAIC, highlighting the necessity for reliable predictive indicators to tailor personalized treatment strategies. This review explores the factors influencing HAIC success, including patient demographics, tumor characteristics, biomarkers, genomic profiles, and advanced imaging techniques such as radiomics and deep learning models. Additionally, the synergistic potential of HAIC combined with immunotherapy and molecular targeted therapies is examined, demonstrating improved survival outcomes. Prognostic scoring systems and nomograms that integrate clinical, molecular, and imaging data are discussed as superior tools for individualized prognostication compared to traditional staging systems. Understanding these predictors is essential for optimizing HAIC efficacy and enhancing survival and quality of life for patients with advanced HCC. Future research directions include large-scale prospective studies, integration of multi-omics data, and advancements in artificial intelligence to refine predictive models and further personalize treatment approaches.

Few published reports have addressed the feasibility of living-donor liver transplantation (LDLT) using elderly donors. We aimed to examine LDLT outcomes in elderly donors and identify clinical factors impacting safely conducted LDLT.

This study was conducted in collaboration with the Japanese Society of Hepatobiliary-Pancreatic Surgery. Data were collected from 140 patients who underwent LDLT using donors aged ≥50 years between 2013 and 2017 at nine collaborating hospitals.

The 1-, 3-, and 5-year graft survival rates in recipients after LDLT employing elderly donors were 84.3%, 78.5%, and 76.3%, respectively, with 6-month mortality of 12.1%. Specific recipient-donor age combinations did not emerge as adverse prognostic factors. A total of 32 recipients (22.9%) had major complications requiring reoperation after LDLT, and 15 donors (10.7%) had major complications of Clavien-Dindo grade ≥II. Multivariate analysis revealed that graft-to-recipient weight ratio (GRWR) <0.84% and neutrophil-to-lymphocyte ratio (NLR) >6.6 were independent predictors of 6-month graft loss after LDLT.

LDLT using elderly donors aged ≥50 years has acceptable graft survival and morbidity rates, and donor age >50 years should not be an absolute contraindication for LDLT. In LDLT involving elderly donors, it is crucial to consider that GRWR <0.84% and NLR >6.6 are adverse prognostic factors. Addressing these factors is necessary to enhance the prognosis, aligning with the increasing public demand for this surgical procedure.

Neutrophil-to-lymphocyte ratio (NLR) is a novel biomarker studied in several autoimmune diseases including inflammatory bowel disease (IBD) in adults but poorly characterized in pediatric IBD (pIBD). We aimed to primarily investigate the relationship between NLR and pIBD endoscopic disease severity. We also examined whether NLR predicted hospitalization, surgery, and therapy response by 52 weeks.

We used the Canadian Children IBD Network prospective inception cohort including patients < 18 years old with baseline data from 2013 to 2022. We excluded patients with concurrent diseases affecting NLR. Both Mayo endoscopic score (MES) and simple endoscopic scale for Crohn's disease (SES-CD) were dichotomized as low activity (quiescent-mild) and high activity (moderate-severe). For therapy responses, we examined year-1 steroid- and biologic-free remission. We used logistic regression for binary outcomes.

A total of 580 patients with ulcerative colitis and 1,081 patients with CD were included. High NLR was associated with high-activity MES and SES-CD in both univariate and multivariable analyses (odds ratio = 1.45, 95% CI = 1.07-1.97, P value = 0.016; and odds ratio = 1.42, 95% CI = 1.04-1.94, P value = 0.026, respectively). We also calculated the best NLR cutoff point to predict MES (1.90, sensitivity = 68%, specificity = 67%, area under the curve [AUC] = 0.67, AUC 95% CI = 0.59-0.74) and SES-CD (2.50, sensitivity = 63%, specificity = 69%, AUC = 0.66, AUC 95% CI = 0.59-0.75) high activity. NLR did not predict therapy response in either ulcerative colitis or CD.

Patients with pIBD with high baseline NLR are more probable to have worse endoscopic disease at diagnosis. This highlights NLR potential as a reliable noninvasive biomarker of disease activity. The predictive power of NLR is based mostly on neutrophils and the balance between neutrophils and lymphocytes.

Evidence on the association between the neutrophil-to-lymphocyte ratio (NLR) and all-cause and cardiovascular disease (CVD) mortality in adults with cancer is limited.

This study aimed to examine the relationship between NLR and all-cause and CVD mortality in adults with cancer.

A retrospective cohort study included 2,639 cancer patients in the U.S. from the NHANES dataset (2005-2018), collecting demographic, laboratory, and mortality data. Multivariable Cox regression analysis, subgroup analysis and restricted cubic spline analyses assessed the associations between NLR and mortality outcomes.

During a median follow-up of 77 months, 713 (27.0%) deaths occurred, including 149 (5.6%) from CVD. Multivariable Cox regression analysis revealed that a high NLR, treated as a continuous variable, was significantly correlated with increased all-cause mortality (HR, 1.09; 95% CI, 1.05-1.12; p < 0.001) and CVD mortality (HR, 1.12; 95% CI, 1.05-1.19; p < 0.001). Meanwhile, when evaluating NLR as a categorical variable, the adjusted hazard ratios (HR) for NLR and all-cause mortality in quartiles Q2 (1.6-2.2), Q3 (2.2-3), and Q4 (>3) were 1.06 (95% CI: 0.83-1.34, p = 0.062), 1.12 (95% CI: 0.89-1.42, p = 0.334), and 1.30 (95% CI: 1.04-1.63, p = 0.021), respectively, when compared with individuals in the lower quartile Q1 (≤1.6). In terms of CVD mortality, the adjusted HR values for NLR in Q2, Q3, and Q4 were 0.92 (95% CI: 0.50-1.69, p = 0.062), 1.24 (95% CI: 0.71-12.19, p = 0.334), and 1.76 (95% CI: 1.04-2.97, p = 0.034), respectively, compared to those in the lower NLR quartile Q1 (≤1.6). Subgroup analysis showed similar patterns (all p-values for interaction > 0.05). Kaplan-Meier analysis indicated lower survival rates for individuals with higher NLR, and RCS analysis suggested a positive linear relationship between NLR and all-cause and CVD mortality.

Elevated NLR is linked to higher all-cause and CVD mortality risks among adults with cancer.

Tumor-associated neutrophils (TANs) play crucial roles in tumor progression, immune response modulation, and the therapeutic outcomes. Despite significant advancements in TAN research, a comprehensive bibliometric analysis that objectively presents the current status and trends in this field is lacking. This study aims to fill this gap by visually analyzing global trends in TANs research using bibliometric and knowledge mapping techniques.

We retrieved articles and reviews related to TANs from the Web of Science core collection database, spanning the period from 2012 to2024. The data was analyzed using bibliometric tools such as Excel 365, CiteSpace, VOSviewer, and Bibliometrix (R-Tool of R-Studio) to identify key trends, influential countries and institutions, collaborative networks. and citation patterns.

A total of 6l5 publications were included in the bibliometric analysis, showing a significant upward trend in TANs research over the last two decades. The United States and China emerged as the leading contributors with the highest number of publications and citations. The journal with the most publications in this field is Frontiers in Immunology, Prominent authors such as Fridlender ZG was identified as the key contributor, with his works frequently cited. The analysis highlighted major research themes. including the role of TANs in tumor microenvironment modulation, their dual functions in tumor promotion and suppression, and the exploration of TANs-targeted therapies, Emerging research hotspots include studies on TANs plasticity and their interactions with other immune cells.

This study is the first to employ bibliometric methods to visualize trends and frontiers in TANs research. The findings provide valuable insights into the evolution of the field, highlighting critical areas for future investigation and potential collaborative opportunities. This comprehensive analysis serves as a crucial resource for researchers and practitioners aiming to advance TAN research and its application in cancer therapy.

Predicting the efficacy of immune-based therapy in patients with unresectable hepatocellular carcinoma (HCC) remains a clinical challenge. This study aims to evaluate the prognostic value of the systemic immune-inflammation index (SII) in forecasting treatment response and survival outcomes for HCC patients undergoing immune-based therapy.

We analyzed a cohort of 268 HCC patients treated with immune-based therapy from January 2019 to March 2023. A training cohort of 93 patients received atezolizumab plus bevacizumab (T + A), while a validation cohort of 175 patients underwent treatment with tyrosine kinase inhibitors (TKIs) combined with anti-PD-(L)1 therapy. The SII cutoff value, determined using X-tile analysis based on overall survival (OS) in the training cohort, divided patients into high (> 752*109) and low (≤ 752*109) SII groups. Prognostic factors were identified through univariate and multivariate logistic and Cox regression analyses, and survival outcomes were assessed using Kaplan-Meier methods. The predictive accuracy of SII was evaluated using receiver operating characteristic (ROC) curves.

An optimal SII cutoff of 752*109 stratified patients into high and low SII groups. Univariate and multivariate logistic regression indicated that SII was a significant predictor of the objective response rate (ORR), which was markedly different between the low and high SII subgroups (34.72% vs. 9.52%, P = 0.019). This finding was consistent in the validation cohort (34.09% vs. 16.28%, P = 0.026). SII also demonstrated prognostic value in Cox regression and Kaplan-Meier analyses. ROC curves confirmed that SII had superior predictive accuracy compared to common clinical indicators, with predictive relevance even in AFP-negative patients. Furthermore, a lower SII was associated with a higher T cell ratio and an increased number of CD8+ T cells and Granzyme B+ CD8+ T cells in peripheral blood.

SII is a promising predictor of both therapeutic efficacy and prognosis in HCC patients undergoing immune-based treatments. Its application may enhance clinical decision-making, thereby improving patient outcomes from immune-based therapy.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a major cause of liver-related morbidity and mortality, contributing to both cardiovascular and non-cardiovascular deaths. The Body Roundness Index (BRI) and Systemic Immune-Inflammation Index (SII) have emerged as predictors of adverse outcomes in metabolic diseases. This study investigates the association between BRI, SII, and mortality risk in MAFLD patients. A nationwide retrospective cohort study was conducted using data from the NHANES database (January 1999-December 2018), including patients diagnosed with MAFLD. BRI and SII were calculated at baseline. Cox proportional hazards models assessed the association between these indices and all-cause, cardiovascular, and non-cardiovascular mortality, adjusting for confounders. Among 12,435 participants diagnosed with MAFLD, 3,381 (27.2%) were classified into the low BRI and low SII group, 2,889 (23.2%) into the low BRI and high SII group, 2,802 (22.5%) into the high BRI and low SII group, and 3,363 (27.1%) into the high BRI and high SII group. Compared to the low BRI and low SII group, the high BRI and high SII group demonstrated significantly higher all-cause mortality, with an adjusted hazard ratio (HR) of 1.89. For cardiovascular mortality, the HR was 2.31, while for non-cardiovascular mortality, the HR was 1.78. The high BRI and high SII cohort exhibited the highest risk of all-cause mortality, cardiovascular mortality, and non-cardiovascular mortality. BRI and SII are independent predictors of mortality in MAFLD patients, and their combined use enhances risk stratification. Integrating these indices into clinical practice could improve personalized management strategies and outcomes in this high-risk population.

The prognostic value of neutrophil-to-lymphocyte ratio (NLR) combined with Model for End-Stage Liver Disease (MELD) score was evaluated for hepatitis B virus-associated decompensated cirrhosis (HBV-DeCi).

The 30-day mortality of 166 hBV-DeCi patients was examined. Receiver operating characteristic curve analysis and multivariate regression analysis were used to assess the performance of NLR for prediction of poor outcomes.

The 30-day mortality rate was 10.2% (17/166). NLR was significantly lower in survivors than in non-survivors, and could be used for prognosis prediction in HBV-DeCi patients. Area under the curve was higher for NLR combined with MELD score than for each factor alone. (MELD score, AUC:0.864、NLR, AUC:0.781, Combined, AUC:0.920) The Odds ratio of MELD score is lower than NLR.(MELD score:1.447&NLR:1.745).

The findings demonstrate that NLR combined with MELD score has a high prognostic value for HBV-DeCi patients.

To examine the associations of healthy lifestyles with risk of all-cause and cause-specific mortality among adults with metabolic dysfunction-associated steatotic liver disease (MASLD), and whether the association was mediated by systemic immune-inflammatory biomarkers (SIIBs).

The study included 10,347 subjects with MASLD, who were enrolled in the Dongfeng-Tongji cohort study. The healthy lifestyles referred to non-smoking, being physically active (≥7.5 metabolic equivalents-hours/week), low-risk alcohol consumption (1-14 g/day for women and 1-28 g/day for men), and optimal sleep duration (≥6 to ≤8 h/day). Cox proportional hazard models were used to examine the relationship between each lifestyle and SIIBs with the risk of all-cause and cause-specific mortality. A mediation analysis was conducted to investigate the role of SIIBs on the association between healthy lifestyles and mortality.

There were 418 MASLD subjects dead till the follow-up of 2018, including 259 deaths from cardiovascular disease (CVD). Compared to MASLD participants with 0-1 healthy lifestyle score (HLS), those with 3-4 HLS had the lowest risk of all-cause mortality [hazard ratio (HR), 0.46; 95% CI, (0.36-0.60)], and CVD mortality [HR (95%CI), 0.41 (0.29-0.58)]. Mediation analyses indicated that SIIBs mediated the association between healthy lifestyles and mortality, with proportions ranging from 2.5% to 6.1%.

These findings suggest that adherence to healthy lifestyles can significantly reduce mortality for MASLD patients, and the decreased SIIBs may partially explain the protection mechanism of healthy lifestyles.

Direct-acting antiviral agents (DAAs) achieve high sustained virologic response (SVR) in chronic hepatitis C patients; yet a proportion of patients still experience de novo liver complications after SVR. Identification of risk factors is clinically important. FIB-4 index is a useful noninvasive tool to assess fibrosis, while neutrophil-to-lymphocyte ratio (NLR) is a biomarker for systemic inflammation. Our study aimed to investigate whether the addition of NLR can increase the prediction power of pre-DAA FIB-4 for de novo liver complications after SVR.

We recruited patients via The Taiwan HCV Registry (TACR) and National Health Insurance Registry Database. The inclusion criteria were patients who achieved SVR12 after DAA and were followed for at least 24 months after SVR12. Liver complications included ascites, hepatic encephalopathy, variceal bleeding, and HCC.

Totally 7657 patients were recruited from 2013 to 2018. Among them, 3674 patients (48.0%) had a FIB-4 value > 3.25 and 491 patients (6.4%) had a NLR >4 before DAA. After two-year of follow-up after SVR 12, 214 patients (2.8%) developed de novo liver complications. Factors associated with liver complications included male gender, diabetes mellitus, hyperlipidemia, chronic kidney disease, and pre-DAA FIB-4 >3.25 in multivariate analyses. Addition of NLR slightly did not increase the power of predicting liver complications.

The overall incidence of de novo liver complications after SVR is low during short-term follow-up. Elevated pre-DAA FIB-4 is associated with de novo liver complications after SVR, whereas the addition of pre-DAA NLR does not increase the prediction power.

It is highly important to be able to predict the therapeutic efficacy of chemotherapy on patients with unresectable advanced or recurrent gastric cancer (GC). The Gustave Roussy Immune Score (GRIm-s) is a predictor of therapeutic sensitivity to chemotherapy and immune checkpoint inhibitors (ICIs) in other cancers. The present study aimed to analyze the association of the GRIm-s with the therapeutic sensitivity of first-line chemotherapy in GC patients.

We included 156 patients receiving primary chemotherapy treatment for unresectable or advanced recurrent GC between January 2012 and December 2021 at our institution. We evaluated the correlation between the GRIm-s and therapeutic sensitivities to chemotherapy. The GRIm-s was assessed before the start of first-line chemotherapy.

Among the 156 patients, 138 (88.5%) and 18 (11.5%) were classified in the low- and high-risk groups, respectively. The GRIm-s high-risk group was significantly older (p = 0.013), had more advanced unresectable cancer (p = 0.0098), and was significantly less likely to progress to second-line chemotherapy (p = 0.014). The overall survival rate (OS) (p = 0.039) and the progression free survival rate (PFS) (p = 0.017) were significantly worse in the GRIm-s high-risk group. The high GRIm-s was an independent prognostic factor for poor survival in multivariate analysis (p = 0.0094).

Focusing on the GRIm-s before first-line chemotherapy initiation for unresectable advanced or postoperative recurrent GC was useful in predicting the therapeutic resistance to chemotherapy, transition to second-line chemotherapy, and poor prognosis.

Objectives: One of the important postoperative complications of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is type 2 endoleak (T2EL). However, there is no well-established biomarker. We aimed to evaluate the validity of the neutrophil-lymphocyte ratio (NLR) as a predictor of T2EL. Methods: Data were retrospectively collected from 146 patients who underwent EVAR for AAA at our institution between April 1, 2008 and March 31, 2021. Within 90 days before surgery, preoperative NLR was calculated from the same blood sample. The receiver operating characteristic curve (ROC) was used to determine the cutoff NLR values for persistent T2EL. Univariate and multivariate analyses were performed. Results: Compared with patients without persistent T2EL, those who had persistent T2EL had lower preoperative NLR (P = 0.041), based on a cutoff value of 1.918, and the entire group was then divided into two groups based on these values for comparison. Univariate analysis showed significant differences in NLR, the white blood cell (WBC) count, the percentage of mural thrombus of aneurysm, history of the hypertension, follow-up term, and aneurysm diameter at final follow-up. Multivariate analysis showed that NLR and AAA diameter on the last follow-up were significantly associated with T2EL persistence. Conclusions: Preoperative low NLR can be a useful predictor of postoperative persistent T2EL.

Objectives. Oral mucositis (OM) is a common adverse reaction associated with chemotherapy. We conducted a six-month longitudinal study to estimate the cumulative incidence of OM during the first six months of chemotherapy in adult patients with cancer other than head and neck cancer. Secondary objectives were as follows: (a) to scrutinize the oral health status of these patients and its evolution during chemotherapy, as assessed by oral health indices; (b) to estimate adherence to prescribed oral hygiene protocol during chemotherapy; and (c) to analyze ulceration-free survival in these patients. Methods. Sixty-four patients participated. Dental health and oral hygiene were assessed at baseline and at the end. Every month, blood tests were performed and oral lesions were recorded. This study was observational, with the only intervention being instruction in the hygiene protocol. The cumulative incidence of OM was estimated with the patient as the unit of analysis. A repeated measures ANOVA was applied to analyze the monthly blood test results. Ulceration-free survival analysis was conducted with adherence to the oral hygiene protocol as a grouping factor, followed by Cox proportional-hazards regression. Results. The six-month cumulative incidence rate was 43.75%, 95%CI (31.58-56.67%) for OM grade 2 or higher. The hazard ratio of ulceration associated with adherence to the hygiene protocol was 0.154, 95%CI (0.049-0.483), adjusted for age, sex, baseline hygiene index, and class of treatment. Conclusions. Compliance with hygiene recommendations would decrease the OM risk by more than six times, compared to non-compliance.

This study aims to investigate preoperative prognostic factors available for intrahepatic cholangiocarcinoma (ICC) patients and propose a new preoperative prognostic scoring system for ICC that combines CA19-9 and neutrophil/lymphocyte ratio (NLR).

In this retrospective analysis, 1728 patients diagnosed with ICC and undergoing curative liver resections were studied. This study employed univariate and multivariate Cox regression to find factors affecting recurrence and overall survival (OS), and furthermore assessed how preoperative models influenced tumor traits and postoperative recurrence.

The results of the multivariate Cox regression analysis indicated that two preoperative variables, NLR and Ca19-9, were independent risk factors affecting postoperative recurrence and OS in ICC patients. Based on this data, assigning a score of 0 (NLR ≤ 2.4 and Ca19-9 ≤ 37U/ml) or 1 (NLR > 2.4 and Ca19-9 > 37U/ml) to these two factors, a preoperative prognostic score was derived. According to the scoring model, patients were divided into three groups: 0 points (low-risk group), 1 point (intermediate-risk group), and 2 points (high-risk group). The 5-year recurrence and OS rates for the three groups were 56.6%, 68.2%, 77.8%, and 56.8%, 40.6%, 27.6%, respectively, with all P values < 0.001. Furthermore, high-risk group patients were more prone to early recurrence (early recurrence rates for high-, intermediate-, and low-risk groups were 56.8%, 51.5%, and 37.1%, respectively, P < 0.001) and extrahepatic metastasis (extrahepatic metastasis rates for high-, intermediate-, and low-risk groups were 31.7%, 26.4%, and 15.4%, respectively, P < 0.001). In terms of tumor characteristics, high-risk group patients had larger tumor diameters and were more likely to experience microvascular invasion, lymph node metastasis, and perineural invasion.

The predictive capacity of postoperative recurrence and OS rates in ICC patients is effectively captured by the preoperative scoring system incorporating NLR and CA19-9 levels.

Surgical therapy is the most optimal treatment for hepatocellular carcinoma (HCC) combined with bile duct tumor thrombus (BDTT) patients. However, whether to perform bile duct resection (BDR) is still controversial. The purpose of this multicenter research is to compare the effect of BDR on the prognosis of extrahepatic BDTT patients.

We collected the data of 111 HCC patients combined with extrahepatic BDTT who underwent radical hepatectomy from June 1, 2004 to December 31, 2021. Those patients had either received hepatectomy with extrahepatic bile duct resection (BDR group) or hepatectomy without bile duct resection (NBDR group). Inverse probability of treatment weighting (IPTW) was used to reduce the potential bias between two groups and balance the influence of confounding factors in baseline data. Then compare the prognosis between the two groups of patients. Cox regression model was used for univariate and multivariate analysis to further determine the independent risk factors that influence the prognosis of HCC-BDTT patients.

There were 38 patients in the BDR group and 73 patients in the NBDR group. Before and after IPTW, there were no statistical significance in OS, RFS and intraoperative median blood loss between the two groups (all P > 0.05). Before IPTW, the median postoperative hospital stay in the NBDR group was shorter (P = 0.046) and the grade of postoperative complications was lower than BDR group (P = 0.014). After IPTW, there was no difference in postoperative hospital stay between the two groups (P > 0.05). The complication grade in the NBDR group was still lower than that in the BDR group (P = 0.046). The univariate analysis showed that TNM stage and portal vein tumor thrombus (PVTT) were significantly correlated with OS (both P < 0.05). Preoperative AFP level, TNM stage and prognostic nutritional index (PNI) were significantly correlated with postoperative RFS (all P < 0.05). Multivariate analysis showed that tumor TNM stage was an independent risk factor for the OS rate (P = 0.014). TNM stage, PNI and AFP were independent predictors of RFS after radical hepatectomy (all P < 0.05).

For HCC-BDTT patients, hepatocellular carcinoma resection combined with choledochotomy to remove the tumor thrombus may benefit more.

To improve liver organ allocation, the model for end-stage liver disease (MELD) score was adopted in candidates reflecting the severity of liver disease and the physical condition of patients. Inflammatory markers are prognostic factors for various cancers and play prognostic roles in patients after liver transplantation (LT) for hepatocellular carcinoma (HCC). Researchers focused more on pre-LT inflammatory markers, while the role of dynamic change of these inflammatory markers is still unknown. The purpose of this study was to estimate the prognostic value of pre-LT and post-LT inflammatory markers.

We collected the pre-LT complete blood count and the post-LT result with highest count of white blood cells within 48 h. Platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio and systemic immune-inflammation index were calculated, and their prognostic roles were analyzed for their MELD scores.

This retrospective two-center cohort study enrolled 290 patients after LT for HCC. Multivariate analysis identified pre-LT PLR as independent risk factor for recurrence-free survival (RFS) [HR (95%CI): 1.002 (1.000-1.003), p = 0.023]. A high pre-LT PLR or post-LT PLR were associated with poorer RFS (p < 0.001 and p = 0.004, respectively). Based on the MELD scores, the pre-LT PLR value was able to predict the RFS in high MELD group (p < 0.001) but had no predictive power in low MELD group (p = 0.076). On the contrary, the post-LT PLR value was better to predict the overall RFS value in low MELD group (p = 0.007) but could not predict the overall RFS value in high MELD group (p = 0.136).

Both pre-LT PLR and post-LT PLR demonstrated prognostic value in patients following LT for HCC. Monitoring PLR values based on the MELD score can improve the predictive prognosis and more effectively guide the individual decisions for the postoperative intervention.

The novel COVID-19 was rapidly spreading and was highly contagious. COVID-19 caused over 6 million deaths worldwide, with high mortality rates, particularly in severe cases.

This study aimed to investigate whether serum albumin-neutrophil count to lymphocyte count ratio (NLR) score (ANS) could be used as a prognostic indicator of COVID-19 severity.

A retrospective study.

Based on the WHO diagnostic criteria, patients were classified as either non-severe (n=270) or severe (n=100).

NLR, serum albumin level and ANS.

The NLR of patients with severe disease was significantly higher than that of those with non-severe disease. Serum albumin levels were significantly lower in patients with severe disease than in those with non-severe disease. The cut-off values representing the maximum potential effectiveness of serum albumin and NLR were 33.5 g/L and 8.25, respectively, according to the Youden index. In patients with severe COVID-19, we observed that the serum albumin level, NLR and ANS were independent prognostic indicators of severe COVID-19 using logistic analysis. The relative risk of severe COVID-19 was 7.65 (95% CI 3.72 to 15.75, p<0.05) in the ANS 2 group compared with that in ANS 0.

ANS could be used as a prognostic indicator of COVID-19 severity.

Previous studies have shown that neutrophil-to-lymphocyte (NLR) ratio at diagnosis and early lymphocytes recovery on doxorubicin-based chemotherapy, may impact the outcome in patients with osteosarcoma (OST). This study aimed to evaluate the prognostic value of hemogram parameters in patients with OST treated with high-dose methotrexate and etoposide/ifosfamide (M-EI) chemotherapy.

We retrospectively analyzed the prognostic value of various hemogram parameters at diagnosis and during therapy in a large consecutive cohort of patients with OST included in the French OS2006 trial and treated with M-EI chemotherapy.

A total of 164 patients were analyzed. The median age was 14.7 years (interquartile range [IQR]: 11.7-17). Median follow-up was 5.6 years (IQR: 3.3-7.7 years). Three-year event-free survival (EFS) and overall survival (OS) were 71.5% (95% confidence interval [CI]: 64%-78%) and 86.4% (95% CI: 80%-91%), respectively. In univariate analysis, blood count parameters at diagnosis and early lymphocyte recovery at Day 14 were not found prognostic of survival outcomes. By contrast, an increase of NLR ratio at Day 1 of the first EI chemotherapy (NLR-W4) was associated with reduced OS in univariate (p = .0044) and multivariate analysis (hazards ratio [HR] = 1.3, 95% CI: 1.1-1.5; p = .002), although not with EFS. After adjustment on histological response and metastatic status, an increase of the ratio NLR-W4 of 1 was associated with an increased risk of death of 30%.

We identified NLR-W4 as a potential early biomarker for survival in patients with OST treated with M-EI chemotherapy. Further studies are required to confirm the prognostic value of NLR and better identify immune mechanisms involved in disease surveillance.

Previous studies have shown that the addition of platinum to neoadjuvant chemotherapy (NAC) improved outcomes for patients with triple-negative breast cancer (TNBC). However, no studies have assessed the efficacy and safety of the combination of taxane and lobaplatin. In this study, we conducted a randomized controlled phase II clinical study to compare the efficacy and safety of taxane combined with lobaplatin or anthracycline.

We randomly allocated patients with stage I-III TNBC into Arm A and Arm B. Arm A received six cycles of taxane combined with lobaplatin (TL). Arm B received six cycles of taxane combined with anthracycline and cyclophosphamide (TEC) or eight cycles of anthracycline combined with cyclophosphamide and sequential use of taxane (EC-T). Both Arms underwent surgery after NAC. The primary endpoint was the pathologic complete response (pCR). Secondary endpoints were event-free survival (EFS), overall survival (OS), and safety.

A total of 103 patients (51 in Arm A and 52 in Arm B) were assessed. The pCR rate of Arm A was significantly higher than that of Arm B (41.2% vs. 21.2%, P = 0.028). Patients with positive lymph nodes and low neutrophil-to-lymphocyte ratio (NLR) benefited significantly more from Arm A than those with negative lymph nodes and high NLR (Pinteraction = 0.001, Pinteraction = 0.012, respectively). There was no significant difference in EFS (P = 0.895) or OS (P = 0.633) between the two arms. The prevalence of grade-3/4 anemia was higher in Arm A (P = 0.015), and the prevalence of grade-3/4 neutropenia was higher in Arm B (P = 0.044).

Neoadjuvant taxane plus lobaplatin has shown better efficacy than taxane plus anthracycline, and both regimens have similar toxicity profiles. This trial may provide a reference for a better combination strategy of immunotherapy in NAC for TNBC in the future.

Diabetic foot ulcer (DFU) is a well-known complication of diabetes and a significant burden on the national health systems. The neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio are inexpensive and easily accessible biomarkers that have proved to be useful in several inflammatory, infectious and cardiovascular diseases. We carried out a comprehensive review examining the association of NLR and PLR with the onset and progression of DFU. PLR and NLR were significantly increased in patients with DFU, compared with a control group of T2DM patients without DFU, and correlate well with DFU severity, evaluated by Wagner and IWGDF grading scales. In patients with diabetic foot infections (DFI), elevated NLR and PLR were correlated with osteomyelitis, increased risk of amputation, and septic complications. The significance of the elevated value of these biomarkers in DFU is related to chronic hyperglycemia and low-grade systemic inflammation, atherosclerotic and vascular complications, and also the associated septic factor. Serial, dynamic follow-up can provide useful information in planning and monitoring DFU treatment, as well as in risk stratification of these vulnerable patients. Further randomized studies are needed to set the cut-off values with clinical significance.

The utilization of inflammation-based scores, such as the Neutrophil-to-Lymphocyte Ratio (NLR), Lymphocyte-to-Monocyte Ratio (LMR), and Platelet-to-Lymphocyte Ratio (PLR), has garnered attention for their potential as prognostic indicators in various cancers. However, their predictive role in patients with intermediate-stage HCC undergoing transcatheter arterial chemoembolization (TACE) remains an area that requires further investigation, as early recognition of TACE refractoriness holds the potential to guide tailored therapeutic interventions.

This multicenter international retrospective study analyzed data from patients with intermediate-stage HCC undergoing TACE between 2018 and 2024. Inflammation-based scores (NLR, LMR, PLR) were assessed preoperatively to predict treatment outcomes.

Two hundred and fourteen patients were enrolled. Preoperative LMR showed the largest area under the curve for the prediction of 6-months PFS, based on the ROC curve analysis. Both high LMR (≥2.24) and low NLR (<4.72) were associated with improved objective response rates and 6-month progression-free survival. Lymphocyte count emerged as a strong predictor of treatment response in both simple (p < 0.001) and multiple (p < 0.001) logistic regression analyses.

This study highlights the prognostic value of inflammation-based scores, particularly LMR and NLR, in predicting the treatment response and short-term outcomes of patients with intermediate-stage HCC undergoing TACE. Future investigations should focus on validating these scores' clinical applicability and assessing their impact on long-term patient survival and therapeutic decision-making.

Lymphocyte-related factors were associated with survival outcome of different types of cancers. Nevertheless, the association between lymphocytes-related factors and tumor response of immunotherapy remains unclear.

This is a retrospective study. Eligible participants included patients with unresectable or advanced hepatocellular carcinoma (HCC) who underwent immunotherapy as their first-line treatment. Radiological assessment of tumor response adhered to RECIST 1.1 and HCC-specific modified RECIST (mRECIST) criteria. Univariate and multivariate logistic analyses were employed to analyze clinical factors associated with tumor response. Kaplan-Meier survivial analysis were employed to compare progression-free survival (PFS) and overall survival (OS) across different clinical factors. Furthermore, patients who received treatment with either a combination of bevacizumab and anti-PD-1(L1) antibody (Beva group) or tyrosine-kinase inhibitor (TKI) and anti-PD-1 antibody (TKI group) were examined to explore the relation between clinical factors and tumor response.

A total of 208 patients were enrolled in this study. The median PFS and OS were 9.84 months and 24.44 months,respectively. An independent factor associated with a more favorable tumor response to immunotherapy was identified when PLR<100. Patients with PLR<100 had longer PFS than other patients, while OS showed no significant difference. Further analysis revealed that PLR exhibited superior prognostic value in patients of the Beva group as compared to those in the TKI group.

There exisits an association between PLR and tumor response as well as survival outcomes in patients receiving immunotherapy, particularly those treated with the combination of bevacizumab and anti-PD-1.

This study aimed to conduct a comprehensive analysis, evaluating the prognostic significance of the baseline Advanced Lung Cancer Inflammation Index (ALI) and Gustave Roussy Immune (GRIm) Score in patients undergoing immune checkpoint inhibitor (ICI) therapy.

A comprehensive search was performed across various databases, including PubMed, the Cochrane Library, EMBASE, and Google Scholar, until October 21, 2023, to compile relevant articles for analysis. The investigation encompassed diverse clinical outcomes, including overall survival (OS) and progression-free survival (PFS).

This analysis included a total of 15 articles, comprising 19 studies involving 3335 patients. Among the 19 studies, nine studies focused on NSCLC, and six studies were conducted on HCC. Pooled results revealed that patients with elevated ALI levels experienced prolonged OS (HR: 0.51, 95% CI: 0.37-0.70, p < 0.001) and extended PFS (HR: 0.61, 95% CI: 0.52-0.72, p < 0.001). Furthermore, a GRIm score > 1 was associated with reduced OS (HR: 2.07, 95% CI: 1.47-2.92, p < 0.001) and diminished PFS (HR: 1.78, 95% CI: 1.35-2.34, p < 0.001) in cancer patients receiving ICIs. Subgroup analysis indicated that ALI cutoff values of 18 exhibited enhanced predictive potential. Additionally, for HCC patients, those with HCC-GRIm score > 2 showed a substantially decreased risk of mortality compared to individuals with HCC-GRIm score ≤ 2 (HR: 2.63, 95% CI: 1.89-3.65, p < 0.001).

The ALI and GRIm score served as dependable prognostic indicators for patients undergoing ICI therapy in the context of cancer treatment.

Preoperative neutrophil-to-lymphocyte ratio (NLR) is a well-known prognostic indicator in various malignancies; however, the impact of postoperative NLR on living donor liver transplant (LDLT) recipients is unknown. Immunotherapy with donor liver-derived activated natural killer (NK) cells may improve postoperative NLR by coactivating immune cells or suppressing activated neutrophils. This study aims to clarify the clinical significance of postoperative NLR in recipients after LDLT with HCC and assess whether immunotherapy improves postoperative NLR.

We conducted a retrospective study of LDLT recipients between 2001 and 2022 to evaluate the clinical significance of postoperative NLR. Furthermore, the correlation between postoperative NLR and the activation marker of infused NK cells was also evaluated. The postoperative NLR was examined 4 weeks after LDLT.

The postoperative high NLR group (N = 78) had preoperative lower NLR and higher model for end-stage liver disease and a higher rate of postoperative infection within 30 days after LDLT than the postoperative low NLR group (N = 41). Postoperative high NLR (hazard ratio [HR], 2.62; 95% confidence interval [CI], 1.01-6.79; P = .047) and nontreatment of immunotherapy (HR, 3.10; 95% CI, 1.33-7.22; P < .01) were independent risk factors for poor overall survival in multivariate analysis. Furthermore, the activation marker of infused NK cells is inversely correlated with decreased postoperative NLR.

The higher level of postoperative NLR was independently associated with poor prognosis in patients after LDLT with HCC. Immunotherapy using activated NK cells may improve postoperative NLR and long-term prognosis.

Herein we used data derived from the SORAMIC trial to explore the predictive value of systemic inflammatory markers (neutrophil-to-lymphocyte ratio [NLR] and platelet-to-lymphocyte ratio [PLR]) in patients with advanced hepatocellular carcinoma (HCC) treated with sorafenib monotherapy or the combination of selective internal radiation therapy (SIRT)/sorafenib.

Patients randomized to sorafenib monotherapy or SIRT/sorafenib within the per-protocol population of the SORAMIC trial were evaluated in this exploratory post hoc analysis. The median baseline values of NLR and PLR were used as cut-off values to describe subgroups. Kaplan-Meier curves with log-rank tests were used to evaluate median survival in the sorafenib and SIRT/sorafenib arms in each subgroup. Multivariable Cox regression analysis was applied to eliminate the effect of confounding factors.

A total of 275 patients with a median overall survival of 12.4 months were included in this analysis. The median NLR value of the cohort was 2.77 and the median PLR was 26.5. There was no significant difference in overall survival between the sorafenib and SIRT/sorafenib arms in patients with low NLR (p = 0.72) and PLR (p = 0.35) values. In patients with high NLR values, there was no statistically significant difference in median overall survival between SIRT/sorafenib and sorafenib cohorts (12.1 vs. 9.2 months, p = 0.21). In patients with high PLR values, overall survival in the SIRT/sorafenib arm was significantly longer than in the sorafenib arm (15.9 vs. 11.0 months, p = 0.029). This significant difference was preserved in the multivariable analysis (SIRT/sorafenib arm: hazard ratio 0.65, 95% CI 0.44-0.96, p = 0.03) incorporating age, Child-Pugh grade, and alpha-fetoprotein levels.

PLR is a potential predictive factor of benefit from additional SIRT in patients with HCC receiving sorafenib therapy. The potential predictive value of PLR should be further evaluated in future trials.

Systemic therapies are the mainstay of treatment in patients with hepatocellular carcinoma at advanced stages. However, not all patients respond well to these treatments. In our analysis, using blood test parameters showing systemic inflammation status, we were able to identify patients who would benefit more from combined treatment with a locoregional treatment of radioembolization (or selective internal radiation therapy).

The established association between the inflammatory marker, neutrophil-lymphocyte ratio (NLR), and both long-term surgical prognosis and short-term postoperative complications is well-recognized. However, its prognostic value in pancreaticoduodenectomy (PD) is yet to be ascertained. This meta-analysis investigates the prognostic relevance of preoperative NLR in PD patients.

We systematically searched electronic databases to identify studies exploring the relationship between pre-treatment blood NLR levels and overall survival (OS), disease-free survival (DFS), and immediate postoperative complications in PD patients. Statistical evaluations, using RevMan 5.4 and Stata 12, focused on hazard ratios (HRs) and risk ratios (RRs). Additionally, subgroup analyses, publication bias tests, and sensitivity analyses were performed.

Our analysis encompassed 18 retrospective studies, with NLR cutoff values ranging from 2 to 3.8. The meta-analysis revealed that PD patients with elevated NLR had diminished OS and DFS, evidenced by an HR of 1.35 (95% CI: 1.11-1.64, p ​= ​0.003) and 1.62 (95% CI: 1.15-2.27, p ​= ​0.005), respectively. Moreover, NLR emerged as an independent determinant of immediate postoperative complications, indicated by an OR of 1.91 (95% CI: 1.01-3.59, p ​= ​0.013) and an HR of 2.15 (95% CI: 1.23-3.73, p ​< ​0.01).

NLR serves as a significant prognostic indicator for both OS and DFS following PD and is a reliable predictor of postoperative complications. Preoperative Neutrophil-to-Lymphocyte Ratio (NLR) is a significant prognostic indicator for overall survival (OS) and disease-free survival (DFS) in patients undergoing pancreaticoduodenectomy (PD).

Systemic immune-inflammatory biomarkers including systemic immune inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) have been demonstrated to be associated with the risk and severity of various liver diseases. However, studies on their role and clinical significance in metabolic diseases, especially in nonalcoholic fatty liver disease (NAFLD), are limited and results are inconsistent.

10821 adults aged 20 years or older were enrolled in this cross-sectional study, sourced from six cycles of the National Health and Nutrition Examination Survey (NHANES). Survey-weighted logistic regression was employed to investigate the correlation between systemic immune-inflammatory biomarkers (SII, NLR, PLR, and LMR) and NAFLD risk. Restricted cubic spline regression models and segmented regression models were used to describe nonlinear relationships and threshold effects. Subgroup and sensitivity analyses were also conducted.

After adjusting for all confounding variables, there was a significant positive association observed between ln-transformed SII (OR= 1.46, 95% CI: 1.27-1.69, P <0.001), NLR (OR= 1.25, 95% CI: 1.05-1.49, P =0.015), LMR (OR= 1.39, 95% CI: 1.14-1.69, P = 0.002) with NAFLD. A nonlinear dose-response relationship with an inverted "U"-shaped threshold of 4.64 was observed between ln(PLR) and NAFLD risk. When ln(PLR) was below 4.64, each unit increase in ln(PLR) was associated with a 0.55-fold increase in the risk of NAFLD (OR= 1.55, 95% CI: 1.05-2.31, P <0.05). Conversely, when ln(PLR) exceeded 4.64, each unit increase in ln(PLR) was associated with a 0.40-fold decrease in the risk of NAFLD (OR= 0.60, 95% CI. 0.44-0.81, P <0.05).

ln-transformed SII, NLR, and LMR were linearly associated with NAFLD risk. ln(PLR) showed an inverted "U"-shaped nonlinear dose-response relationship with the risk of NAFLD.

Limited data are available regarding ALI's clinical relevance and prognostic value in patients with hepatocellular carcinoma (HCC) after hepatectomy.

HCC patients who received hepatectomy at the Meizhou People's Hospital from May 2011 to February 2022 were enrolled in the study cohort. The ALI was calculated as follows: ALI = BMI (kg/m2) × ALB (g/dL)/(absolute neutrophil count/absolute lymphocyte count). The primary outcome was overall survival (OS). The secondary outcome was cancer-specific survival (CSS). Univariate and multivariate Cox regression analyses were performed, followed by nomogram construction and decision curve analysis (DCA).

425 HCC patients were enrolled for analyses. Lower preoperative ALI was significantly correlated with incomplete tumor capsule and advanced tumor stage. Lower preoperative ALI was an adverse independent prognostic factor for OS (HR: 1.512, 95% CI: 1.122-2.039, P 0.007) and CSS (HR: 1.754, 95% CI: 1.262-2.438, P <0.001) in HCC patients. The nomogram plot was built based on three (including age, TNM stage, and ALI) and two (including TNM stage and ALI) independent prognostic factors for OS and CSS, respectively. Further analyses indicated that the nomogram had better predictive value and some net benefit than the traditional TNM stage alone, especially in long-term OS.

Our study further indicated that ALI could be a prognostic marker for OS and CSS in HCC patients after hepatectomy, especially in long-term OS.

To investigate the prognostic value of platelet-to-lymphocyte ratio (PLR) in patients with unresectable hepatocellular carcinoma (uHCC) treated with transarterial chemoembolization (TACE) and tailored tyrosine kinase inhibitors (TKIs) plus immune checkpoints inhibitors (ICIs).

Ninety-eight patients from May 2018 to January 2022 in our hospital were enrolled in this study. The receiver operating characteristic (ROC) curve analysis was performed and the corresponding Youden index was used to determine the optimal PLR cut-off. Overall survival (OS), progression-free survival (PFS), and adverse events (AEs) of patients were evaluated based on the PLR cut-off. The factors affecting survival were assessed using univariate and multivariate Cox proportional hazards regression analyses.

The PLR cut-off was 98.89. There were 49 patients in the low pretreatment PLR group (PLR ≤ 98.89) and 49 patients in the high PLR group (PLR > 98.89). Patients with low pretreatment PLR had significantly longer median OS (25.7 months vs 16.1 months; P < 0.001) and PFS (14.9 months vs 10.2 months; P < 0.001) than those with high pretreatment PLR. The multivariate analysis revealed that ALT, tumor size, and PLR are risk factors affecting OS. The three independent factors affecting PFS are tumor size, AFP, and PLR. The AEs were tolerable and manageable.

The low pretreatment PLR (PLR ≤ 98.89) was an independent protective factor for the survival outcomes of patients in this study. PLR was helpful for clinicians to predict the prognosis and identify the patients with uHCC who were most likely to benefit from TACE + TKIs + ICIs.

The recent rise in non-alcoholic fatty liver disease (NAFLD) among children and adolescents led to a thorough investigation of the peculiarities of the cellular infiltrate which characterize the disease at young ages. This review aims to highlight the key involvement of neutrophils in the pathogenesis of pediatric NAFLD and the potential biomarker role of neutrophil-to-lymphocyte ratio (NLR) in the same pediatric disorder. Neutrophils, which are first responders to inflammation, constitute an abundant component of an infiltrate which is particularly disposed within the portal area of children with NAFLD. The involvement of neutrophils in triggering liver fibrosis has been related amongst others to reactive oxygen species (ROS) production, to the stimulation of hepatic stellate cells, and to their synthesis of neutrophil elastase. As immune imbalance characterizes NAFLD, potentially emerging non-invasive biomarkers such as NLR have been proposed for the detection and prognosis of NAFLD. In adults, several studies asserted the role of NLR in the prediction of advancing liver fibrosis and mortality in subjects with NAFLD. In children, data is scarce with contradicting findings, as some studies failed to identify significant shifting in NLR values in children with NAFLD when compared with obese controls without liver impairment. However, NLR seems to significantly increase in children with obesity and different degrees of NAFLD when compared to healthy counterparts and their changes seem to be reversible with weight loss. Still, paucity of pediatric studies calls for future research addressing the role of NLR in predicting NAFLD development and progression in children with obesity.

To clarify the Japan criteria (JC), as proposed in 2019, in order to identify the most appropriate treatment methods for hepatocellular carcinoma (HCC) recurrence and assess the feasibility of pre-living donor liver transplantation (LDLT) downstaging within these criteria.

The subjects of this study were 169 LDLT patients with HCC recurrence. We performed univariate and multivariate analyses of the factors contributing to HCC recurrence after LDLT and clarified the post-transplant outcomes of pre-LDLT downstaging.

Univariate and multivariate analysis identified beyond the JC (p = 0.0018) and a neutrophil-to-lymphocyte ratio > 2.01 (p = 0.029) as independent risk factors. Patients who met the JC had significantly higher recurrence-free and overall survival rates after LDLT (p < 0.0001) than those who did not (p = 0.0002). The post-transplant outcomes of patients within the JC after downstaging were significantly better than those of patients beyond the JC (p = 0.034) and equivalent to those within the JC without downstaging.

Even for HCC recurrence, the JC could play an important role in deciding on the best treatment strategy, and downstaging within the JC had good post-transplant outcomes.

We report a multicenter, phase 2 study evaluating the efficacy of pucotenlimab, an anti-PD-1 antibody, in patients with mismatch repair-deficient (dMMR) or microsatellite instability-high (MSI-H) tumors, and potential biomarkers for response. Overall, 100 patients with previously treated, advanced solid tumors centrally confirmed as dMMR or MSI-H received pucotenlimab at 200 mg every 3 weeks. The most common cancer type is colorectal cancer (n = 71). With a median follow-up of 22.5 months, the objective response rate is 49.0% (95% confidence interval 38.86%-59.20%) as assessed by the independent review committee, while the median progression-free survival and overall survival have not been reached. Grade ≥3 treatment-related adverse events were observed in 18 patients. For the biomarker analysis, responders are enriched in patients with mutations in the KMT2D gene. Pucotenlimab is an effective treatment option for previously treated advanced dMMR/MSI-H solid tumors, and the predictive value of KMT2D mutation warrants further research. This study is registered with ClinicalTrials.gov: NCT03704246.

In the era of immunotherapy, identifying biomarkers of immune system activation has become a high-priority challenge. The blood neutrophil-to-lymphocyte ratio (NLR) has been largely investigated as a biomarker in several cancer types. NLR values have been shown to mirror the tumor-induced inflammatory status and have been demonstrated to be a reliable prognostic tool across stages of disease and therapeutic approaches. When integrated with other biomarkers of response to immunotherapy, such as PD-L1, tumor mutational burden, and tumor-associated immune cells, the NLR may allow to further stratify patients with different likelihoods of deriving a significant clinical benefit. However, despite its accessibility, low cost, and easy interpretation, the NLR is still poorly used as a prognostic tool in daily clinical practice. In this review, we analyze the role of the NLR in defining the relationship between cancer and the immune system, its usefulness in daily clinical practice, and its relationship with other established or emerging biomarkers of immunotherapy outcomes.
