ABSTRACT
Postoperative complications contribute to recurrences and poor long-term outcomes for gastric cancer patients, especially among the elderly. However, the prognostic effect of postoperative complications on non-cancer-related death in elderly patients with gastric cancer has not been reported. Two hundred and twenty elderly (> 75 years of age) patients with stage I gastric cancer were retrospectively identified from consecutive admissions between 1995 and 2020. Non-cancer-related death following gastrectomy occurred in 13.6% (30/220) of patients. Non-cancer-related death was associated with respiratory disease in 46.7% (14/30) of cases. Although there was no association with any preoperative comorbidities, postoperative complications [P < 0.001, HR 4.16 (95% CI: 1.91-9.02)] and open gastrectomy [P=0.002, HR 3.87 (95% CI: 1.54-9.66)] were indepe ndently associated with a poorer prognosis for non-cancer-related death. Poor nutritional status [P=0.028, OR 4.25 (95% CI: 1.17-15.4)] was an independent risk factor for postoperative complications. Postoperative complications shortened life expectancy from 8.8 years to 6.1 years. Specifically, postoperative complications shortened life expectancy from 6.7 years to 3.9 years in elderly patients over 80 years of age. Postoperative complications and open gastrectomy affected the incidence of non-cancer-related death among elderly patients with gastric cancer, primarily attributed to respiratory disease. Efforts should be made to perform minimally invasive surgery, improve preoperative nutrition, and avoid postoperative complications.
