Abstract:
Objective To assess the evolution of gastric epithelial dysplasia (GED). Methods We reviewed the history of 239 of patients with gastric dysplasia diagnosed by endoscopic biopsy, and 195 were followed up for 61. 37 months. Results Among 239 cases of dysplasia (261 lesions) , there were 119, with mild dysplasia, 77 with moderate dysplasia, and 43 with severe dysplasia. The gastric dysplasia lesions are mainly in lesser curvature, and its endoscopic appearance mostly is localized erosion. In the follow - up group, regression of dysplasia was demonstrated in 86. 36% , 81. 25% , and 47. 62% of mild, moderate and severe dysplasia respectively. Progression to gastric cancer was detected in 8. 18% , 15. 63% , and 72. 09% of mild, moderate, and severe dysplasia, respectively. The relative risk (RR) of mild, moderate, severe dysplasia was 1. 96, 3. 74, and 17. 25 respectively. Conclusion Carcinomatous evolution of GED increases proportionally with its histological grade. Gastroscopy biopsy follow-up should be held up for all grades of GED, especially, in high grade GED, gastroscopy and biopsy should be taken as soon as possible.
