Objectives:
This study aimed to investigate the validity of laparoscopic gastric cancer surgery in elderly patients.
Methods:
A total of 202 patients who underwent laparoscopic gastrectomy for gastric cancer between January 2007 and December 2016 were divided into an elderly group (age ≥75 years, n = 36) and a control group (age < 75 years, n = 166). The patients' clinicopathological data were reviewed.
Results:
The overall morbidity rate was relatively higher in the elderly group (16.7 vs. 11.4%, p = 0.389), whereas the incidence of serious complications ≥grade III according to the Clavien-Dindo classification did not increase significantly in the elderly group (8.3 vs. 7.8%, p = 0.920). Univariate and multivariate analyses revealed that age ≥75 years was not a significant predictive factor of postoperative morbidity (p = 0.568). There was no significant difference in the 5-year overall survival rate of patients with pathological stage I gastric cancer between the groups (97.1 vs. 96.1%, p = 0.704; hazard ratio, 0.669; 95% confidence interval, 0.036-3.692).
Conclusions:
Laparoscopic gastrectomy has an acceptable morbidity rate in elderly patients, and the long-term outcome of patients with stage I gastric cancer was similar to that of the control group.
