Abstract
Clinicopathological data obtained in 174 cases of early gastric carcinoma were reviewed. They covered 183 lesions composed of 88 intramucosal lesions (m) and 95 submucosal lesions (sm). Of the 183 lesions, 46 (25.2%) were of a protruded or an elevated type, and 135 (73.7%) of a depressed or an excavated type, while 2 were of a flat type. Thus, the depressed type (IIc) was predominant. Furthermore, of the 183 lesions, about 58% developed in the middle part (M) of the stomach, about 40% in the lower part (A), and slightly over 2% in the upper part (C).
Histologically papillary adenocarcinomas were of the protruded or elevated type and about 86% of poorly differentiated adenocarcinomas came under the depressed or excavated type. No metastasis occurred in any type when cancer cells remained within the mucosa. When cancer cells invaded the submucosa, the incidence of metastasis was 23/ 174 (13.2%) in early gastric cancer, and was somewhat higher in IIa + IIc type cancer. Lymph node metastases were noted in the primary (n1)or second (n2)group but not in the third group. These results suggest that resection of early gastric cancer should be coupled with cleaning the lymph nodes in the first 2 groups as a rule. The 5-year survival rate in our patients was 98%.
Early gastric carcinoma was classified histologically and its possible relation to intestinal metaplasia in the perifocal mucosa was sought by the Tes-tape method.
Résumé
La définition du cancer précoce de l'estomac qui a été proposée par la Société d'endoscopie gastroentérologique du Japon en 1962 est la suivante: infiltration cellulaire néoplasique limitée à la muqueuse et à la sous muqueuse sans tenir compte de la présence de metastases ou du volume de la tumeur. Le nombre de cancers gastriques précoces atteignit 183 lésions pour 174 cas opérés pendant la période s'étendant de 1967 à 1979 dans notre service. Le propos de cet article est de faire part de notre expérience basée sur l'interprétation des constatations cliniques et pathologiques.
