THE OUTCOME OF SURGICAL-TREATMENT FOR GASTRIC-CARCINOMA IN THE ELDERLY

Surgeons are increasingly being faced with the problem of treating eld erly gastric carcinoma patients. The purpose of this study was to eluc idate the feasibility of surgical treatment for these patients. Among 4740 gastric carcinoma patients treated from 1971 to 1990, 112 (2.4%) were aged 80 or over. The results of treatment in this elderly group w ere compared retrospectively with those in 2664 younger gastric carcin oma patients (aged 50-69, control group, 56.2%). The TNM stage distrib ution and the curative resection rates (75.9 vs 81.4%) were similar be tween the groups. Reduced nodal dissection was more common in the elde rly group. The elderly had a higher incidence of preoperative risk fac tors (76.8 vs 53.1%) and 90-day mortality (10.7 vs 3.9%). However, the postoperative complication rates were similar between the groups. The 90-day mortality rates in the elderly group were higher in the subgro ups undergoing total gastrectomy or D2 dissection. In the patients wit hout pre-existing morbidity, the 30-day mortality, 90-day mortality an d postoperative complications were similar between the groups. The 5-y ear survival rate after curative resection of the elderly group was si gnificantly lower than that of the control group (44.4 vs 74.0%). This difference lost significance when non-cancer death was excluded (62.5 vs 79.9%). We believe that, although gastrectomy can be carried out s afely in elderly patients, extended surgery should be limited to those without preoperative morbidity.
