Background and Objectives Carbohydrate antigen 72‐4 (CA72‐4) is widely used and has been associated with poor prognosis in gastric cancer (GC), but the prognostic significance of elevated preoperative CA72‐4 that normalizes after resection remains unknown. Methods This retrospective cohort analysis was conducted at the Sun Yat‐Sen University Cancer Center (SYSUCC). Consecutive patients ( n  = 1179) with GC who had undergone curative resection for stage Ⅰto Ⅲ gastric adenocarcinoma. The patients were grouped into three cohorts: normal preoperative CA72‐4 (C1), elevated preoperative but normalized postoperative CA72‐4 (C2), and elevated preoperative and postoperative CA72‐4 (C3). Results In total, 1179 patients were identified. Kaplan‐Meier analysis showed that patients with normal preoperative CA72‐4 had a longer overall survival (OS) ( p  < .001) and recurrence‐free survival (RFS) ( p  < .001) than those with elevated preoperative CA72‐4. Patients with C1 had a longer OS and RFS than those with C2 or C3. Moreover, patients with C3 had the lowest OS, but had similar RFS to patients with C2. Multivariate Cox regression analysis showed that elevated pre‐ or postoperative CA72‐4 was independently associated with shorter OS (hazard ratio [HR] = 1.273; 95% confidence interval [CI], 1.026–1.580; p  = .029) and RFS (HR = 1.333; 95% CI, 1.064–1.668; p  = .012). Conclusions Both elevated preoperative and postoperative CA72‐4 can well predict the poor prognosis of patients with GC. Therefore, routine measurement of both postoperative and preoperative CA72‐4 is warranted.
