Impact of Gastric Cancer Surgery in Elderly Patients.

OBJECTIVES: This study aimed to investigate the validity of gastric cancer surgery in elderly patients.

METHODS: A total of 544 patients who underwent elective gastrectomy for gastric cancer were divided into an elderly group (age ≥75 years, n = 171) and a control group (age <75 years, n = 373). The clinicopathological data of the patients were reviewed.

RESULTS: The overall morbidity rate (26.3 vs. 16.1%, p = 0.005) and the incidence rate of anastomotic leakage (6.4 vs. 1.6%, p = 0.003) were significantly higher in the elderly group. The proportion of patients who had severe complications (≥grade IIIa) was relatively higher in the elderly group (10.5 vs. 5.7%); however, the difference was not significant (p = 0.074). A stage-matched survival analysis revealed no significant differences between the groups (stage I: p = 0.978; stage II: p = 0.964; stage III: p = 0.199). For the pathological stages II and III, the overall survival of the patients in the elderly group who received adjuvant chemotherapy for >3 months was significantly better than that of the patients who received it for ≤3 months or did not receive it (p = 0.023).

CONCLUSIONS: An aggressive treatment strategy should be adopted in selected elderly patients with gastric cancer.
