“…The gastric cancer in the elderly is often relatively advanced (Colluccia et al 1987). However in Japan, the incidence of early gastric cancer was about 50% (Nagata et al 1983). The rate was only 25% in the present elderly study.…”

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 pancreaticosplenectomy 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.

“…However, gastric cancer still remains the reading cause of cancer death in Japan. A recent detection rate of early gastric cancer has been reached to about 50% (Nagata et al 1983). However, upper gastric cancer, including cardia cancer, the rate for early gastric cancer was 12% in our recent study (Tanaka et al 1990), in comparison with 4% for Europe.…”

We reviewed the 639 cases of early gastric cancer from nation-wide 16 medical centers. The proportion of early gastric cancer among surgically resected gastric carcinoma comprised 6 to 12 percent. Male to female ratio was 1.7 to 1 with male preponderance. Mean ages of the early gastric cancer was 49.0 years and most prevalent ages was 5th decade. Macroscopically type IIc was most prevalent, reaching 59.9 percent. Depressed type lesions was more frequent than elevated type lesions by four folds. The size of lesions less than 4 cm accounted for more than 80 percent. Most frequent site of lesions were lower third by the CMA classification and lesser curvature transectionally. Lymph node metastasis was observed in 10.9 percent of all cases and it was more frequent in large tumor size more than 4 cm, elevated type, and undifferentiated carcinoma. 5-year survival rate was 91.6 percent. Gastrofiberscopic examination was superior to that of radiological examination in the diagnosis of early gastric cancer.
