DPC4/SMAD4在子宫内膜癌中的表达及意义

Expression of Smad4 protein in endometrial carcinoma and its significance

目的探讨Smad4蛋白在子宫内膜癌中的表达情况及其意义。方法应用免疫组织化学SP方法检测 56例子宫内膜癌Smad4的表达情况,并与 30例正常子宫内膜和 42例各型增生性子宫内膜对比。结果Smad4在子宫内膜癌中的表达明显低于正常子宫内膜和单纯性增生性子宫内膜(P<0. 01,P<0. 05),且与组织学分级及临床分期明显相关 (P<0. 01,P<0. 05),而与肌层浸润深度无关。结论Smad4蛋白的表达可能在子宫内膜癌的发生发展及判断预后方面具有重要作用,可作为重要的生物学标记物。

Objective To investigate the expression of in endometrial carcinoma and its clinical significance. Methods Smad4 protein was detected in 56 endometrial carcinoma samples and 72 normal or/and benign hypertrophic endometrium samples by immunohistochemical SP method. Results Compared with normal controls and single hyperplasia, Smad4 protein was decreased in endometrial carcinoma tissue (P<0.01, P<0.05). The expression of Smad4 was correlated with histological grade and clinical stage (P<0.01, P<0.05),while no significant difference was detected in tumors of different myometrial carcinoma samples. Conclusion Smad4 protein may play an important role in the development and prognosis of endometrial carcinoma. It may be used as an important biological marker in endometrial carcinoma.
