The incidence of gastric cancer in Japan is very high, even among elderly people over 70 years of age. From January 1976 to December 1988, Red Cross Medical Center in Japan performed an operation on 1,076 patients with gastric cancer, of whom 276 were over 70 years of age (elderly group) and 794 were under the age of 70 (young group). The average age of the elderly group was 74.2±3.8 years (70-85 years old), and the young group was 53.3 years old ± 10.4 years old. 914 cases were surgically removed, including 223 cases in the elderly group and 691 cases in the young group. The resection rates were 80.7% and 87%, respectively, with significant differences (P<0.05). Total gastrectomy was performed in 66 of the elderly group and 232 of the young group, accounting for 26.9% and 33.5% of the surgically removed group, respectively. The lymph node dissection rate was 81.7% and 88.0% in the old and young groups, respectively. 90% of elderly patients and 34.9% of young patients have
