BACKGROUND: The high incidence of gastric cancer among the octogenarians and nonagenarians (oldest old; age ≥ 80 years) is emerging as an important management issue. Herein, we report both the short-term outcomes and long-term survival results of standard radical gastrectomy in this group of patients. METHODS: This was a retrospective review of 164 oldest old patients (older group) and 2,258 younger patients (age <80 years; younger group) with gastric cancer who underwent curative resection between January 1994 and December 2006. Clinicopathologic data, long-term survival, and prognostic factors were analyzed. RESULTS: Clinical tumor stage did not differ between the two groups at the time of diagnosis. Higher Charlson comorbidity index scores (≥ 5) were observed in the older group than in the younger group; this was associated with higher postoperative morbidity (P = 0.035) and in-hospital mortality rates (P = 0.015) in the older group. At a median follow-up of 37.8 months, the overall survival rate for the older group was lower than that for the younger group (P < 0.001). However, the cumulative incidence of gastric cancer-related deaths was comparable between the two groups. Nodal involvement and metastatic to retrieved lymph node ratio were the only independent predictors of survival in the older group. CONCLUSIONS: Patients in the older group had a higher postoperative morbidity rate but comparable cancer-specific survival. Careful patient selection for gastrectomy is warranted in elderly patients, particularly those with high-grade nodal involvement.
