The tumor microenvironment of colorectal cancer (CRC) is heterogenous; thus, it is likely that multiple immune-related and inflammatory markers are simultaneously expressed in the tumor. The aim of this study was to identify immune-related and inflammatory markers expressed in freshly frozen CRC tissues and to investigate whether they are related to the clinicopathological features and prognosis of CRC. Seventy patients with CRC who underwent curative surgical resection between December 2014 and January 2017 were included in this study. Tissue samples were obtained from tumor and non-tumor areas in the patients’ colons. The concentrations of immune-related markers (APRIL/TNFSF13, BAFF, LAG-3, PD-1, PD-L1, and CTLA-4) and inflammatory markers (CHIT, MMP-3, osteocalcin, pentraxin-3, sTNF-R1, and sTNF-R2) in the samples were measured using the Bio-plex Multiplex Immunoassay system. The concentrations of APRIL/TNFSF13, BAFF, and MMP-3 in the samples were significantly high; thus, we conducted analyses based on the cut-off values for these three markers. The high-APRIL/TNFSH13-expression group showed a significantly higher rate of metastatic lesions than the low-expression group, whereas the high-MMP-3-expression group had higher CEA levels, more lymph node metastases, and more advanced disease stages than the low-expression group. The five-year disease-free survival of the high-MMP-3-expression group was significantly shorter than that of the low-expression group (65.1% vs. 90.2%, p = 0.033). This study provides evidence that the APRIL/TNFSF13, BAFF, and MMP-3 pathway is overexpressed in CRC tissues and is associated with unfavorable clinicopathological features and poor prognosis in CRC patients. These markers could serve as diagnostic or prognostic biomarkers for CRC.

Purpose: Fournier gangrene (FG) is a life-threatening condition characterized by rapid tissue necrosis in the perineal and genital regions. Early identification of risk factors is essential for improving prognosis and reducing mortality rates. This study aimed to identify predictive factors associated with mortality in patients with FG.Methods: A multi-institutional retrospective study was conducted across four tertiary care centers in Korea, including patients diagnosed with FG between January 2014 and December 2023. Data on demographic characteristics, laboratory findings, and clinical outcomes were collected. Independent risk factors for mortality were identified using multivariate logistic regression analysis, and optimal cutoff values for these predictors were determined.Results: A total of 133 patients were included. The findings showed that age, initial lactate level, hemoglobin level, platelet count, and albumin level were significant predictors of mortality. Age was associated with an odds ratio of 1.105 (95% confidence interval [CI], 1.038–1.177; P=0.0018), while initial lactate level exhibited an odds ratio of 1.820 (95% CI, 1.335–2.480; P=0.0002). The optimal cutoff values identified were 64.5 years for age, 3.15 mmol/L for lactate, 8.65 g/dL for hemoglobin, 208×109/L for platelet count, and 3.05 g/dL for albumin, with varying sensitivity and specificity.Conclusion: The study concluded that age, and initial levels of lactate, hemoglobin, albumin, and platelet count are independently predictive of mortality in patients with FG. These findings underscore the importance of aggressive management for patients presenting with abnormal serum values at admission to improve clinical outcomes. Further research is warranted to validate these results and to refine management strategies for FG.
