Abstract Background Identifying the most effective postoperative surveillance interval in patients with gastric cancer (GC) remains challenging. To elucidate a logical and schedule, we analyzed GC recurrence risk trends after gastrectomy using hazard function. Methods We retrospectively reviewed medical records of 2503 who underwent curative resection between 2000 2018. examined over time influence clinicopathological variables on it. Results Overall, recurred 291 (11.6%) median 64.6 months. Recurrence was highest at approximately 11-months postoperatively (hazard rate [HR]: 0.0045), decreasing to half peak 39-months postoperatively. Patients Stage I maintained low risk. In II patients, peaked 16-months (HR: 0.006) gradually declined thereafter. III had 11 months 0.019), plateauing 40 Conclusions demonstrated significant stage-dependent differences postsurgical by Reductions intensity might be acceptable according individual recurrence.
