This work is based on the follow‐up evaluation of 67 moderate (MD) or severe gastric dysplasias (SD) diagnosed by endoscopic biopsy. Forty‐one patients had moderate gastric dysplasia, 22 (53.65%) had regression of MD, 14 patients (34.4%) had persistence, three (7.31%) had progression to SD, and two (4.87%) had transformation in gastric adenocarcinoma. Twenty‐six patients were diagnosed with severe gastric dysplasia: in 12 patients (46.15%) gastric lesions regressed to normality (five cases), mild (six cases) or moderate dysplasia (one case); six patients (23.07%) showed persistent histologic changes of SD in the subsequent biopsy specimens; eight patients (30.7%) presented progression of lesions to gastric adenocarcinoma after 1 to 79 months of follow‐up evaluation. The authors conclude that moderate and severe gastric dysplasias are preneoplastic lesions and a valuable marker of gastric cancer risk; the risk of gastric cancer after moderate or severe dysplasia is of 9.52%, excluding those cases with short follow‐up. The authors claim that these patients may receive a conservative clinical treatment with frequent endoscopic studies until the appearance of either early carcinoma to indicate gastrectomy, or no dysplasia at all or mild dysplasia in specimens from at least two consecutive biopsies.
