摘要
肠上皮化生和异型增生是胃粘膜病变中最重要的变化,它们被视为癌前病变。作者收集异型增生190例,轻度118例、中度50例、重度22例。71例肠化型异型增生作粘液组织化学染色,含硫酸粘液的结肠型肠化30例,全部病例均见小肠型肠化生。21例异型增生随访观察表明,轻中度异型增生变化不大,而6例重度异型增生中有3例在两年内发展成癌。
Intestinal metaplasia and epithelial dysplasia are the most important lesions of gastric mucosa and are regarded as precancerous. The authors collected 190 cases of gastric dysplasia, in which there were 118 mild, 50 moderate and 22 severe cases. The dysplastic lesions were classified into 3 types, cryptal, adenomatoid and regeneration-related dysplasia. Thr 71 specimens of gastric dysplasia with intestinal metaplasia were stained foe mucin. The results showed that colonic metaplasia associated with sulfomucin was present in 30 specimens and small-intestine type metaplasia was present in all of them. Twenty-one cases were followed up : 15 cases of mild to moderate dysplasia remained stationary, while 3 out of the 6 severe cases developed gastric carcinoma in 2 years' time.
