With advances in gastric cancer treatment, survival outcomes following surgery have improved; however, recurrence remains a significant challenge. Postoperative follow-up is crucial for the early detection of recurrence, enabling timely intervention and improving long-term survival. In patients who undergo curative resection of gastric cancer, postoperative surveillance typically includes regular esophagogastroduodenoscopy, blood tests—including tumor marker assessments—and imaging studies such as computed tomography. However, there is limited evidence that such follow-up strategies contribute to improved long-term survival. Multiple international guidelines recommend postoperative follow-up schedules and strategies based on retrospective studies and expert opinions. The impact of Helicobacter pylori eradication on long-term outcomes after gastric cancer surgery remains a subject of ongoing debate. Secondary primary cancer following gastric cancer treatment is another issue during postoperative follow-up. Optimizing follow-ups using an individualized, evidence-based approach is crucial.
