Associations between clinicopathological variables and OS were evaluated using independent sample tests, Kaplan–Meier survival analysis, and Log rank tests. A Cox proportional hazards model was employed to identify independent predictors of OS.Results: Of 1452 patients, 58.9% were male and 41.1% female (ratio 1.43:1). Multivariate logistic regression identified age, tumor differentiation, preoperative CEA, and metastasis as independent mortality predictors (all P ≤ 0.01; Table 1). A univariate analysis of this predominantly rectal-cancer cohort (51.9%) revealed that numerous clinicopathological variables, including age, tumor size, grade, tumor deposits, perineural and vascular invasion, nodal status, surgical margins, clinical stage, primary site, preoperative CEA, treatment modality, distant metastasis, and recurrence, were each significantly associated with overall survival (Table 2). In the overall cohort, age ≥ 75 years (OR = 3.812), poor differentiation (OR = 2.590), elevated CEA (OR = 4.594), and liver metastasis (OR = 4.370) were independently associated with higher mortality (all P ≤ 0.045; Table 3). Subgroup analyses (Table 4) showed that in colon cancer, age ≥ 75 years (OR = 4.961, P = 0.001) and metastasis (OR = 37.029, P
