[Preneoplastic lesions associated with carcinoma of the stomach: retrospective study of 125 gastrectomy pieces].
A study was made of 125 gastrectomy pieces with gastric carcinoma in which metaplastic and dysplastic changes on the intact gastric mucosa adjacent to the tumor were analyzed. Both incomplete intestinal metaplasia and different types of dysplasia were more frequently and significantly associated with carcinomas of intestinal pattern than with diffuse ones (p less than 0.001). Jass type I dysplasia was more frequent in well-differentiated carcinomas, while Jass type II was more common in relatively undifferentiated tumors, the difference being highly significant (p less than 0.001). Our results and those of other studies in the literature suggest a pathogenic relationship only between preneoplastic lesions and gastric carcinoma of intestinal pattern, which probably includes entities that can be differentiated by pathogenesis to judge from the variations in the dysplastic changes observed.
