Gastric cancer surgery in the elderly.

Abstract

Although there is a decreasing number of gastric cancer patients in Japan, the number of patients over 80 years of age is increasing. Forty patients over 80 years of age (from 80 to 88 years) with gastric cancer (Group 1) during the 10 years from 1980 to 1989 were retrospectively investigated and compared with those 70-79 years of age (Group 2). The resectability rate was 80% in Group 1 and 89% in Group 2. Early gastric cancer was observed at a rate of only 25% in Group 1 and 39% in Group 2. Pathologically, the differentiated type occurred in 78% of those in Group 1 and 68% of Group 2. Total gastrectomy was performed in only 6% of the resected cases in Group 1 and in 25% of Group 2. A combined resection including such operations as pancreatico-splenectomy or splenectomy (PS) was employed in none of the total gastrectomy cases in Group 1 and in 30% of Group 2. R3 gastrectomy was performed in none of the patients in Group 1 and in 21% of those in Group 2. Postoperative complications occurred in 25% of Group 1 patients and in 12% of Group 2 patients. Anastomotic leakage occurred in 3% of those in Group 1 and in 4% of those in Group 2. The 5-year survival rate was 47% for all the resected cases in Group 1 and 68% for Group 2. The 5-year survival rate was 61% for those who underwent a curative (radical) gastrectomy in Group 1, and 84% for those in Group 2.
