摘要: 目的: 探讨脆性组氨酸三联体(FHIT) 基因和p53 基因在胃癌中的表达及其与临床病理因素的关系。方法: 采用免疫组化SP 法检测78 例胃癌组织中FHIT 和p53 的表达。结果: FHIT 和p53 在胃癌中表达率分别为43. 6 %和52. 6 %。FHIT 蛋白的丢失在胃癌中占56. 4 % ,两者与胃癌的组织类型、浸润深度、临床分期和淋巴结转移状况无关( P > 0. 05) 。结论: ①胃癌组织中FHIT 蛋白的丢失是频发事件,FHIT 可能是胃癌发生中重要的候选抑癌基因; ②测定FHIT 和p53 的表达,可用于高 危人群的筛选。

Abstract: Purpose : To investigate the expression of f ragile histidine t riad(FHIT) and p53 in gast ric carcinoma ( GC) and their relationship to clinicopathological factors. Methods : Seventy2eight cases of GC were studied using immunohistochemical technigue. Results : The positive rates of FHIT and p53 gene expression were 43. 6 % and 52. 6 % respectively. No correlation was found between the FHIT and p53 expression and their clinico2 pathological factors such as histological type , lymph node metastasis and staging. Conclusion : ①Loss of FHIT expression is a f requent event in GC and FHIT gene may be one of the important candidate tumor suppressor gene in carcinogenesis of GC; ②Detection of FHIT and p53 expression in biopsy specimens might be useful inscreening of high2risk population.

Key words: Gastric carcinoma, fragile histidine triad, p53
