title: [Incipient and intermediate gastric cancer II. Anatomo-pathological and surgical aspects. Cooperative study in 13 hospitals].
abstract: Anatomic and surgical characteristics of 233 pts with early, and 120 with intermediate gastric cancer, from 13 hospitals in Chile are analyzed. 63% had depressed or excavated lesions. Most of the tumors were located in the inferior or middle third, while only 17% of the early carcinomas were found in the superior third of the stomach, specially in the lesser curvature. 5% had residual tumor in the gastric remanent. Histologically, tubular adenocarcinoma was the most common finding. According to Lauren's classification intestinal carcinoma was more frequent than the diffuse type. Surgeons underestimated lymphatic node involvement (macroscopic appreciation) in up to 58% of the cases when compared to the pathologists observation (microscopic appreciation). This was specially true in muscular carcinomas. The incidence of lymphatic metastases was 6% in mucous, 12% in submucous and 57% in muscular carcinoma. The need of complete lymph node dissection of all the lymphatic barriers is emphasized.
