Abstract
Thirty-five patients who had been operated on because of elevated-type early gastric cancer during the period between 1966 and 1985 were analysed from both clinical and pathologic viewpoints. As they included 2 patients with double carcinoma of the stomach, the number of lesions studied was 37. Most patients were over 40 years of age, and the frequency of patients over 60 years old was 57.1%. The male to female ratio was 6 to 1. The purely elevated-type was observed most frequently, and elevated types with depressed or flat surfaces were less frequent. The lesions were distributed at the antrum (59.7%), body (29.7%), and cardia (10.8%). The purely elevated type was found more frequently in the intramucosal carcinoma (m) group than in the submucosal invasion (sm) group. The types combined with depressed or flat forms were found frequently in the sm group. As regards the histologic types of carcinoma, differentiated type was found in 83.3% of all lesions examined. Blood vessel and lymphatic invasion were observed in 13.8% and 37.9% of cases, respectively. INF classification revealed that 90% of the m group belonged to INFα and 80% of the sm group to INFγ. Five-year survival rate was 94.7%, and only one patient died of recurrence of the carcinoma.
