ABSTRACT
Molecular studies have identified various treatment-related prognostic molecules to enhance the effectiveness of colorectal cancer (CRC) treatment and improve survival rates. The expression of cathepsin V in gastrointestinal cancer cells prompted an investigation into its potential as a prognostic indicator for CRC. The evaluation of cathepsin V expression and its clinicopathological significance was conducted through immunohistochemistry in a tissue microarray, encompassing 142 CRC and normal colorectal tissues. Overall and disease-free survival rates, based on cathepsin V expression levels, were assessed using the Kaplan-Meier method and compared utilizing the log-rank test. Univariate and multivariate analyses, employing a Cox proportional hazards model, were performed to identify prognostic factors. Cathepsin V expression exhibited no correlation with age, sex, tumor location, tumor size, or histological grade. However, it was significantly correlated with depth of tumor invasion, regional lymph node (LN) metastasis, distant metastasis, and lymphovascular involvement (all p<0.001). Overall and disease-free survival rates were significantly better with low cathepsin V expression than with high expression (p<0.001). Univariate analysis identified several prognostic factors, including histological grade (low vs. high), tumor size (≤ vs. >5â¯cm), tumor depth (T1 vs. ≥T2), regional LN metastasis, distant metastasis, tumor-node-metastasis (TNM) stage (Stage I vs ≥II), lymphovascular involvement, and cathepsin V expression. Multivariate analysis revealed that tumor depth, distant metastasis, and cathepsin V expression are independent predictors of poor survival. Cathepsin V is frequently expressed in CRC, and its high expression is associated with poor prognosis. Therefore, cathepsin V is a useful prognostic marker for CRC.
