Univariate and multivariate analysis using a Cox proportional hazard model further identified CDH17 expression as an independent prognostic predictor for both the postoperative OS (HR [95% CI]: 2.296 [1.154–4.968], p = 0.0240; Table 3) and RFS (HR [95% CI]: 2.489 [1.062–6.494], p = 0.0447; Table 3) in CRC patients. The gene discussed is CDH17; the disease is colorectal carcinoma.
