Core Tip

Core tip: Although the outcomes of patients with advanced gastric cancer have gradually improved with the development of adjuvant therapies, a large number of patients experience disease recurrence after curative gastrectomy. To optimize the management of each individual patient, accurate markers to predict prognosis are needed. In this multicenter dataset analysis, we found that evaluation of the serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels both before and after surgery provides more precise risk stratification of patients with stage II/III gastric cancer. Patients with high postoperative CEA and CA19-9 levels are at high risk of disease recurrence, and intensive postoperative management to detect hematogenous recurrences should be considered.
