Impact of Routine Follow-Ups After Curative Gastrectomy in Elderly Patients with Early Gastric Cancer.

INTRODUCTION

Elderly patients with early gastric cancer exhibit a relatively shorter life expectancy and lower recurrence risk, prompting consideration of whether the regular follow-up strategy should apply to this demographic. This study was designed to determine the effect of routine postoperative follow-up on the elderly patients, specifically those pathologically diagnosed with stage I gastric cancer.

METHODS AND MATERIALS

This retrospective analysis was conducted at a single tertiary center and enrolled patients aged ≥ 75 years who underwent curative gastrectomy for stage I gastric cancer between January of 2007 and December of 2016. The patients were divided into routine and nonroutine follow-up groups, depending on whether the recommended follow-up examinations (endoscopy, CT, and blood tests) were complete. Propensity score matching was performed to compare the overall survival (OS) and disease-specific survival (DSS) between the two study groups.

RESULTS

Among 385 patients enrolled, 301 (78.2%) were routine and 84 (21.8%) were nonroutine follow-up patients. After propensity score matching, each study group consisted of 83 patients. There was no significant difference in OS (85.5% vs. 83.1%, p = 0.47) and DSS (98.6% vs. 98.3%, p = 0.57) between the two study groups. There were six (1.5%) recurrences in the entire cohort: four in the routine and two in the nonroutine follow-up group.

CONCLUSIONS

Regular follow-up of elderly patients with stage I gastric cancer did not significantly impact the OS and DSS rates.
