Early gastric carcinoma with special reference to macroscopic classification

Cancer. 1987 Sep 1;60(5):1099-106. doi: 10.1002/1097-0142(19870901)60:5<1099::aid-cncr2820600530>3.0.co;2-f.


During a period beginning in 1946 and ending in October of 1978, 1000 cases of solitary early gastric carcinoma were operated on at the Cancer Institute Hospital, Tokyo, Japan. The clinical characteristics and the macroscopic and chronological changes were studied in these cases. Early gastric carcinoma comprised one third of all resected gastric carcinoma. If early gastric carcinoma was divided into two groups, the depressed and the elevated, the former was more common. By location, the depressed type lesions were more frequently seen in the middle third of the stomach and the elevated type lesions in the lower third. By age, distribution of the elevated type lesions showed a peak with a mode at the age of 60 to 69 years and of the depressed type, a plateau with a mode at the age of 50 to 59 years. The relative incidence of the elevated type of gastric carcinoma to the depressed type was one to four. In depth of invasion, the mucosa and the submucosa were equally involved. Lymph node metastases were encountered in 12.7% of early gastric carcinoma cases. The incidence of positive nodes in mucosal carcinoma was 3.4% and that of submucosal lesions was 21.7%. Of the elevated type carcinoma, 20.9% of the cases had positive nodes. The 5-year survival rate of the patients with surgery for cure was 93.8% in contrast to 56.5% of those with palliative resection.
