OBJECTIVES:
Gastric cancer (GC) is the fifth most common cancer and the third leading cause of cancer-related death worldwide, posing a serious threat to public health. Prognostication of overall survival (OS) in patients undergoing radical gastrectomy remains a clinical priority. Evidence suggests that preoperative nutritional and inflammatory status correlated with postoperative outcomes. This study aims to evaluate the prognostic value of the skeletal muscle index at the third lumbar vertebra (L3-SMI) as a trichotomous variable and to compare the performance of commonly used nutritional and inflammation-related indicators in predicting postoperative survival in GC patients.
METHODS:
This retrospective study analyzed clinical data of patients who underwent radical gastrectomy with neoadjuvant chemotherapy between 2011 and 2018 at the Department of Gastrointestinal Surgery, Xiangya Hospital of Central South University. L3-SMI was measured by preoperative CT, and 8 preoperative nutritional/inflammatory indices were calculated from the latest laboratory tests before surgery: neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), pan-immune-inflammation value (PIV), albumin-globulin ratio (AGR), and prognostic nutritional index (PNI). L3-SMI was categorized into 3 groups using X-tiler software. ROC curves were used to determine optimal cut-off values for the other eight indices. Kaplan-Meier curves and univariate/multivariate Cox proportional hazards models were used to analyze the association between variables and OS. Concordance index (C-index) and subgroup analysis assessed predictive performance and consistency across patient subgroups.
RESULTS:
A total of 546 patients were included, with a minimum follow-up time of 36 months. Kaplan-Meier and univariate analysis showed that L3-SMI and the 8 indicators were significantly associated with OS (all P<0.01). After adjusting for age, gender, tumor site, differentiation, pTNM stage, type of surgery, anemia, CEA, and AFP, multifactorial Cox analysis revealed that L3-SMI (HR=0.676, 95% CI 0.523 to 0.872), AGR (HR=0.611, 95% CI 0.452 to 0.827), and PNI (HR=0.590, 95% CI 0.418 to 0.833) were independent predictors of OS. The full model confirmed the independent prognostic roles of L3-SMI, AGR, and PNI. Among all indicators, PNI had the highest C-index for 1-year OS prediction (0.632, 95% CI 0.568 to 0.695), while AGR showed the best performance at 3 years (0.585, 95% CI 0.548 to 0.622) and 5 years (0.578, 95% CI 0.542 to 0.613). Subgroup analysis indicated that higher L3-SMI, AGR, and PNI were associated with lower mortality risk in patients aged<65 years, with lower gastric tumors, poor differentiation, stage III pTNM, or who underwent subtotal gastrectomy.
CONCLUSIONS
Compared with other indicators, preoperative nutritional markers such as L3-SMI, AGR, and PNI demonstrated superior prognostic value for OS in gastric cancer patients undergoing radical gastrectomy. Assessing these indices can help identify patients at high risk of poor prognosis, thereby guiding targeted nutritional interventions and potentially improving survival outcomes.

Objective:To investigate optimal treatment strategy for pT3N0 laryngeal squamous cell carcinoma(SCC). Methods:A retrospective study of 150 patients with pT3N0 laryngeal SCC treated in the First Affiliated Hospital of Chongqing Medical University was performed. The efficacies of partial laryngectomy and total laryngectomy, as well as surgery alone and postoperative radiotherapy were evaluated. The overall survival(OS), disease specific survival(DSS) and disease-free survival(DFS) were analyzed with statistical package from SPSS. Results:Among the 108 patients with glottic laryngeal SCC, there were no significant differences in OS, DSS and DFS between the partial laryngectomy group and the total laryngectomy group(Log-rank=0.184, 0.010 and 0.051, P>0.05). Similarly, there were no significant differences in OS, DSS and DFS between the surgery-alone group and postoperative radiotherapy group(Log-rank=0.214, 0.251 and 0.003, P>0.05). Among the 38 patients with supraglottic laryngeal SCC, the OS in the total laryngectomy group was significantly higher than that in the partial laryngectomy group(Log-rank=7.338, P=0.007). The DSS and DFS in the total laryngectomy group were higher than in the partial laryngectomy group, but the differences were not statistically significant(Log-rank=0.895 and 1.792; P>0.05). The DFS in the postoperative radiotherapy group was significantly higher than in the surgery-alone group(Log-rank=7.172, P=0.007), but there were no significant differences in OS and DSS between these two groups(Log-rank=0.010 and 0.876, P>0.05). Conclusion:For pT3N0 glottic laryngeal cancer patients, the efficacy of partial laryngectomy is comparable to total laryngectomy, same as surgery alone and postoperative radiotherapy. For pT3N0 supraglottic laryngeal cancer patients, total laryngectomy could improve the overall survival, and postoperative radiotherapy could reduce the recurrence. Prospectively randomized study with large samples is still needed.

Objective:To investigate the expression of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues and analyze their expression levels in relation to clinical features and prognosis. Methods:From January 1, 2019, to December 31, 2019, 69 cases of nasopharyngeal carcinoma tissues and adjacent non-cancerous tissues were collected from patients treated at Yunnan Cancer Hospital. Immunohistochemistry was employed to detect the expression of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues. The Kaplan-Meier method was used to predict survival time, and the clinicopathological features were evaluated using the log-Rank test. Results:The positive expression rates of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues were 87.0% and 84.5%, respectively. Compared to adjacent normal tissues, the expression levels of NFAT5 and IGF1R in nasopharyngeal carcinoma tissues were significantly increased (P<0.05). Furthermore, the expression of NFAT5 and IGF1R was positively correlated with T stage, N stage, skull base invasion, and cranial nerve palsy (P<0.05). The overexpression of NFAT5 and IGF1R significantly affected the survival rate of patients with nasopharyngeal carcinoma and was negatively correlated with prognosis (P<0.05). Conclusion:In nasopharyngeal carcinoma tissues, overexpression of NFAT5 and IGF1R is observed, which is closely linked to clinical features and patient outcomes. These markers may serve as valuable indicators for predicting the prognosis of nasopharyngeal carcinoma.

Objective:Retrospective analysis of the correlation between clinicopathologic features and related indexes and prognosis in patients with recurrent nasopharyngeal carcinoma. Methods:One hundred and eight nasopharyngeal cancer(NPC) patients with post-treatment recurrence in Yunnan Cancer Hospital from January 2013 to January 2018 were collected, and the survival time was estimated by Kaplan-Meier method, and clinicopathological characteristics were analyzed by log-rank test; risk factors and prognosis were analyzed by Cox proportional risk model for single-factor and multifactorial analysis. A P-value <0.05 was considered statistically significant. Results:The median survival of all patients was 54 months, with a 3-year survival rate of 80.2% and a 5-year survival rate of 39.8%. The 5-year overall survival rate was 50.2% for patients >46 years old and 27.9% for patients ≤46 years old(P<0.05), a statistically significant difference. Univariate analysis showed that overall survival was associated with age, chemotherapy regimen, EBV early antigen IgA, plasma D-dimer, glycan antigen-125, γ-interferon, α-tumor necrosis factor, IL-10, and IL-4(P<0.05). Multifactorial analysis revealed that age, chemotherapy regimen, EBV early antigen IgA, plasma D-dimer, glycan antigen-125, and interleukin 10 were independent influences on the prognosis of recurrent nasopharyngeal carcinoma(P<0.05). Conclusion:Differences in chemotherapy regimens affect the prognosis of recurrent nasopharyngeal carcinoma. Elevated plasma D-dimer, glycan antigen 125, and interleukin 10 levels affect the overall survival of recurrent nasopharyngeal carcinoma, which may be a valid independent prognostic factor, and are expected to provide new biomarkers for nasopharyngeal carcinoma in the clinic.

Objective:This study aims to investigate the influence of microvessel density(MVD) and microlymphatic vessel density(MLVD) on the prognosis of patients with hypopharyngeal squamous cell carcinoma(HPSCC) and to develop a nomogram prediction model for prognosis based on pathological characteristics. Methods:A retrospective analysis was conducted on clinicopathological and follow-up data from HPSCC patients who underwent surgical treatment at our institution between June 2010 and June 2020. Immunohistochemical staining was performed on tumor tissues and adjacent normal margin tissues to evaluate MVD and MLVD. The associations among MVD, MLVD, and clinicopathological features were analyzed. Univariate and multivariate Cox regression analyses were conducted to identify independent risk factors affecting overall survival(OS). Based on these findings, a nomogram model was constructed and its predictive accuracy was assessed using C-index, receiver operating characteristic(ROC) curve, and calibration curve. Results:Both MVD and MLVD were significantly higher in HPSCC tumor tissues compared to normal tissues. Patients in the high MVD and high MLVD groups exhibited significantly lower OS rates than those in the low MVD and low MLVD groups. Multivariate Cox regression analysis revealed that N stage, recurrence, nerve invasion, lymph node capsule invasion, MVD, and MLVD were independent prognostic factors of OS. Based on these factors, a nomogram prognosis model was successfully constructed. The nomograms demonstrated superior performance in terms of C-index, area under the ROC curve, and calibration, outperforming the AJCC TNM staging system. Conclusion:Elevated MVD and MLVD levels are associated with poorer prognosis in HPSCC patients. The nomogram model based on pathological features provides valuable insights for clinical assessment and decision-making.

OBJECTIVES:
To analyze the differences in the prognosis of gastric signet ring cell carcinoma (SRCC) among different races using the US Surveillance Epidemiology and End Results (SEER) database and The Cancer Genome Atlas (TCGA) database.
METHODS:
We analyzed the data of patients with gastric SRCC from the SEER database from 2000 to 2020, and divided the patients into cohorts of whites, blacks, Asians or Pacific Islanders, American Indians/Alaska Natives according to their race. The prognosis and treatment of the cohorts were evaluated using baseline demographic analysis, Kamplan-Meier survival curve, and nomogram analysis.
RESULTS:
We analyzed the data of a total of 2058 patients, including 8.6% blacks, 72.4% whites, 16.6% Asians or Pacific Islanders, 1.0% American Indians/Alaska Natives, and 1.4% other races. The tumor grade varied among different races, and the prevalence and survival rates of patients differed significantly across races. The differences in the white cohort were the most prominent, and all the differences were statistically significant (P<0.05). Racial differences were also noted in patient management and prognosis.
CONCLUSIONS
There are racial differences in tumor grades and prognosis of gastric SRCC, and these differences provide evidence for optimizing clinical diagnosis and treatment strategies for this malignancy.

OBJECTIVE:
To elucidate the predictive value of norepinephrine equivalence (NEE) score on the 28-day death risk in patients with sepsis and provide evidence for its application in the diagnosis and treatment of sepsis and septic shock.
METHODS:
A retrospective cohort study was conducted based on the data of patients with sepsis from Medical Information Mart for Intensive Care-IV 2.2 (MIMIC-IV 2.2). The patients who received vasoactive agents within 6 hours after the diagnosis of sepsis or septic shock were enrolled, and they were divided into survival and non-survival groups based on their 28-day outcomes. The baseline characteristics, vital signs, and treatment data were collected. Multivariate Cox regression analysis was performed to identify factors influencing the 28-day death risk. Receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of various parameters on the 28-day death risk of septic patients. Kaplan-Meier survival curve was used to evaluate cumulative survival rate in patients classified by different quantitative parameters based on the cut-off values obtained from ROC curve analysis.
RESULTS:
A total of 7 744 patients who met the Sepsis-3 diagnostic criteria and received vasopressor treatment within 6 hours post-diagnosis were enrolled, of which 5 997 cases survived and 1 747 died, with the 28-day mortality of 22.6%. Significant differences were observed between the two groups regarding age, gender, height, body weight, race, type of intensive care unit (ICU), acute physiology and chronic health evaluation II (APACHE II) score, sequential organ failure assessment (SOFA) score, Charlson comorbidity index (CCI) score, underlying comorbidities, and vital signs. Compared with the survival group, the non-survival group had poorer blood routine, liver and kidney function, coagulation function, blood gas analysis and other indicators. Multivariate Cox regression analysis revealed that age > 65 years old [hazard ratio (HR) = 0.892, 95% confidence interval (95%CI) was 0.801-0.994, P = 0.039] and male (HR = 0.735, 95%CI was 0.669-0.808, P < 0.001) were protective factors for 28-day death in patients with sepsis, and NEE score (HR = 1.040, 95%CI was 1.021-1.060, P < 0.001), shock index (HR = 1.840, 95%CI was 1.675-2.022, P < 0.001), APACHE II score (HR = 1.076, 95%CI was 1.069-1.083, P < 0.001), SOFA score (HR = 1.035, 95%CI was 1.015-1.056, P < 0.001), and CCI score (HR = 1.135, 95%CI was 1.115-1.155, P < 0.001) were independent risk factors for 28-day death in septic patients. ROC curve analysis showed that the area under the ROC curve (AUC) of NEE score for predicting the 28-day death risk of septic patients was 0.743 (95%CI was 0.730-0.756), which was comparable to the predictive value of APACHE II score (AUC = 0.742, 95%CI was 0.729-0.755) and ratio of mean arterial pressure (MAP)/NEE score (MAP/NEE; AUC = 0.738, 95%CI was 0.725-0.751, both P > 0.05), and better than SOFA score (AUC = 0.609, 95%CI was 0.594-0.624), CCI score (AUC = 0.658, 95%CI was 0.644-0.673), shock index (AUC = 0.613, 95%CI was 0.597-0.629) and ratio of diastolic blood pressure (DBP)/NEE score (DBP/NEE; AUC = 0.735, 95%CI was 0.721-0.748, all P < 0.05). According to the cut-off values of APACHE II and NEE scores obtained from ROC curve analysis, the patients were stratified for Kaplan-Meier survival curve analysis, and the results showed that the 28-day cumulative survival rate in the septic patients with an APACHE II score ≤ 22.5 was significantly higher than that in those with an APACHE II > 22.5 (Log-Rank test: χ2 = 848.600, P < 0.001), and the 28-day cumulative survival rate in the septic patients with an NEE score ≤0.120 was significantly higher than that in those with an NEE score > 0.120 (Log-Rank test: χ2 = 832.449, P < 0.001).
CONCLUSIONS
NEE score is an independent risk factor for 28-day death in septic patients who received vasoactive treatment within 6 hours of diagnosis and possesses significant predictive value. It can be used for severity stratification in sepsis management.

Biomedical and Environmental Sciences 2025;38(5):571-584
OBJECTIVE:
To describe survival trends and global patterns of esophageal cancer (EC) using survival data from population-based cancer registries.
METHODS:
We systematically searched PubMed, EMBASE, Web of Science, SEER, and SinoMed databases for articles published up to 31 December 2023. Eligible EC survival estimates were evaluated according to country or region, period, sex, age group, pathology, and disease stage.
RESULTS:
After 2010, Jordan exhibited the highest age-standardized 5-year relative survival rates (RSRs)/net survival rates (NSRs) at 41.1% between 2010 and 2014, while India had the lowest, at 4.1%. Survival rates generally improved with diagnostic age across most countries, with significant increases in South Korea and China, of 12.7% and 10.5% between 2000 and 2017, respectively. Survival was higher among women compared to men, ranging from 0.4%-10.9%. Survival rates for adenocarcinoma and squamous cell carcinoma were similar, differing by about 4%. In China, the highest age-standardized RSRs/NSRs was 33.4% between 2015 and 2017. Meanwhile, the lowest was 5.3%, in Qidong (Jiangsu province) between 1992-1996.
CONCLUSION
Global EC survival rates have improved significantly in recent decades, but substantial geographical, sex, and age disparities still exist. In Asia, squamous cell carcinoma demonstrated superior survival rates compared to adenocarcinoma, while the opposite trend was observed in Western countries. Future research should clarify the prognostic factors influencing EC survival and tailor prevention and screening strategies to the changing EC survival patterns.

Objective To investigate the relationships of the expression of microRNA-487a-3p (miR-487a-3p) and A kinase-interacting protein 1 (AKIP1) mRNA in the endometrial cancer (EC) tissue with the patient survival within 5 years after surgery. Methods The EC tissue and adjacent normal tissue samples were collected from 130 EC patients who underwent surgical treatment at the Fourth Hospital of Shijiazhuang from September 2016 to April 2019.qRT-PCR was employed to determine the expression levels of miR-487a-3p and AKIP1 mRNA.The patients were followed up for 5 years after surgery to record the survival status.After removal of the patients who missed follow-up,78 surviving patients were recorded as the EC survival group,and 34 deceased patients were recorded as the EC death group.The dual luciferase reporter gene assay was conducted to verify the targeting relationship between miR-487a-3p and AKIP1 mRNA.Comparison was conducted for the expression levels of miR-487a-3p and AKIP1 mRNA between adjacent normal tissue and EC tissue,the expression levels of miR-487a-3p and AKIP1 mRNA in the EC tissue among patients with different clinical pathological parameters,and the clinical pathological parameters and the expression levels of miR-487a-3p and AKIP1 mRNA in the EC tissue between the EC survival group and the EC death group.The correlations of miR-487a-3p and AKIP1 mRNA levels in the EC tissue with the degree of tumor differentiation,International Federation of Gynecology and Obstetrics (FIGO) stage,lymph node metastasis,and depth of muscle invasion were analyzed.The relationships of miR-487a-3p and AKIP1 mRNA with patient prognosis and the risk factors affecting the survival of EC patients within 5 years after surgery were analyzed to evaluate the value of miR-487a-3p and AKIP1 mRNA levels in predicting the survival of EC patients within 5 years after survival. Results The EC tissue showed lower miR-487a-3p level (0.41±0.08 vs. 1.00±0.05;t=71.306,P<0.001) and higher AKIP1 mRNA level (2.35±0.37 vs. 1.00±0.03;t=41.465,P<0.001) than the adjacent normal tissue.The miR-487a-3p low expression group and AKIP1 mRNA high expression group had higher proportions of patients with low tumor differentiation,FIGO stage Ⅲ to Ⅳ,lymph node metastasis,and deep invasion of muscle layer than the miR-487a-3p high expression group and AKIP1 mRNA low expression group,respectively (all P<0.05).The results of dual luciferase reporter gene assay showed that the relative activity of luciferase in the miR-487a-3p small interfering RNA (siRNA)+AKIP1 mRNA-wild type (WT) group was higher than that in the miR-487a-3p empty vector+AKIP1 mRNA-WT group (2.85±0.19 vs. 1.00±0.04;t=23.339,P<0.001).There was no significant difference in the relative activity of luciferase between the miR-487a-3p empty vector+AKIP1 mRNA-mutant type (MUT) group and the miR-487a-3p siRNA+AKIP1 mRNA-MUT group (1.04±0.05 vs. 1.05±0.03;t=0.420,P=0.683).MiR-487a-3p in the EC tissue had negative correlations with AKIP1 mRNA,FIGO stage,lymph node metastasis,and depth of muscle invasion and a positive correlation with the degree of tumor differentiation (all P<0.001).AKIP1 mRNA had positive correlations with FIGO stage,lymph node metastasis,and depth of muscle invasion and a negative correlation with the degree of tumor differentiation (all P<0.001).The 5-year overall survival rates in the miR-487a-3p high expression group and AKIP1 mRNA low expression group (89.47% and 84.91%) were higher than those in the miR-487a-3p low expression group and AKIP1 mRNA high expression group (49.09% and 55.93%),respectively (both P<0.05).The EC death group had higher proportions of patients with low tumor differentiation,FIGO stage Ⅲ to Ⅳ,lymph node metastasis,and deep invasion of muscle layer,higher AKIP1 mRNA level in the EC tissue,and lower miR-487a-3p level than the EC survival group (all P<0.05).Low tumor differentiation,FIGO stage Ⅲ to Ⅳ,lymph node metastasis,deep invasion of muscle layer,low miR-487a-3p level,and high AKIP1 mRNA level were independent risk factors for the survival of EC patients within 5 years after surgery (all P<0.05).The area under curve (AUC) values of miR-487a-3p and AKIP1 mRNA alone (0.785 and 0.789,respectively) were lower than that of their combination (0.908) in predicting the survival of EC patients within 5 years after surgery (both P<0.05). Conclusion The EC tissue has a low miR-487a-3p level and a high AKIP1 mRNA level,both of which are correlated with clinicopathological parameters and prognosis and can be used to predict the survival of EC patients within 5 years after surgery.
