Hazard rates of recurrence for gastric cancer after curative resection: implications for postoperative surveillance.

ABSTRACT:

Background

Identifying the most effective postoperative surveillance interval in patients with gastric cancer (GC) remains challenging. To elucidate a logical and effective surveillance schedule, we analyzed GC recurrence risk trends after gastrectomy using the hazard function.

Methods

We retrospectively reviewed the medical records of 2503 patients who underwent curative GC resection between 2000 and 2018. We examined recurrence risk over time and the influence of clinicopathological variables on it.

Results

Overall, GC recurred in 291 patients (11.6%) over a median of 64.6 months. Recurrence risk was highest at approximately 11-months postoperatively (hazard rate [HR]: 0.0045), decreasing to half the peak at approximately 39-months postoperatively. Patients with Sta
