原癌基因C-met和雌激素受体在子宫内膜癌中的表达及相关性的探讨

目的　了解子宫内膜癌组织中原癌基因 C- m et和雌激素受体 (ER)的表达状况 ,探讨内膜癌中 C- met的表达与 ER的关系。方法　采用免疫组化 SP法。结果判断采用组织化学记分 (H值 ) ,H值≥ 70为阳性表达。结果　宫内膜癌中 C- met表达随手术 -病理分期及组织学分级的增加而增强 ,ER的表达随着手术 -病理分期及组织学分级的增加而减弱。C- met表达与 ER呈负相关趋势 (r=- 0 .5 84 2 ,P<0 .0 5 )。结论　在子宫内膜癌中 ,C- m et的表达与 ER表达呈负相关 ,两者联合使用对宫内膜癌的激素治疗 ,预后判断等方面有重要意义

Expression and Correlation of C-met and Estrogen Receptor in Endometrial Carcinomas

OBJECTIVE: To investigate the expression and correlation of C-met and Estrogen receptor (ER) in endometrial carcinomas. METHODS: We examined 55 samples of endometrial carcinomas using specific polyclonal endometrial carcinomas. METHODS: antibody and monoclonal antibody correspondent to the human C-met and ER respectively. The histochemical score was estimated according to the formula H = (i + 1) x pi, with a criterion of equal or more than 70 as considered to be positive in expression. RESULTS: The expression of C-met was correlated with both histological grade and clinical stage of endometrial carcinomas. The H scores of carcinomas in grade 3 was higher than in grade 1 and grade 2, while higher H scores were found in carcinomas in stage III and II compared to stage I (P < 0.05). The higher of the grade and stage were, the weaker the ER were expressed in endometrial carcinomas (P < 0.05). There was an inverse correlation between the expression of ER and C-met (r = -0.5842 P < 0.05). CONCLUSIONS: The expression of C-met and ER might be a useful predictor for the prognosis of endometrial carcinomas and an indicator to evaluate the effectiveness of the hormone intervention.
