In univariate analysis, tumor diameter (p < 0.001), histological differentiation (p = 0.029), pathological TNM (pTNM) stage (p < 0.001), LMR (hazard ratio [HR], 2.866; p < 0.001), NLR (HR, 2.778; p < 0.001), PLR (HR, 2.803; p = 0.001), C-reactive protein (CRP) level (p = 0.003), carcinoembryonic antigen (CEA) (p = 0.011), and postoperative chemotherapy (p < 0.001) were significantly associated with CSS. This evidence concerns the gene CEACAM5 and neoplasm.
