title: Gastric dysplasia: a ten-year follow-up study.
abstract: The results of a ten-year follow-up study on gastric dysplasia (GD) are reported. A total of 260 cases were diagnosed, 125 of which had an adequate follow-up, 81 Low Grade Dysplasia (LGD) and 44 High Grade Dysplasia (HGD). Patients with LGD were younger than patients with HGD, while no significant difference in the mean age was found between HGD and carcinoma. LGD regressed in 49.4% of cases, persisted in 18.5% and progressed in 32.1%. HGD regressed in 4.6%, persisted in 13.6% and progressed in 81.8%. In some cases dysplasia reappeared after a long-time interval of apparent regression. In 58 cases progression to cancer was observed: in 35 cases dysplasia was associated with carcinoma (8 LGD and 27 HGD), while in 23 cases dysplasia evolved into carcinoma (14 LGD and 9 HGD). There was a good correlation between the accuracy in following up the patients and the chance of diagnosing the carcinoma at an early stage. The importance of gastric dysplasia as a marker for carcinoma, its precancerous nature and the treatment of the patients are discussed.
