摘要
目的 研究血栓调节蛋白 (TM )在子宫内膜癌组织中的表达及其与肿瘤的浸润程度、组织学分级等病理参数的关系。方法 应用免疫组织化学SP法对 5 0例子宫内膜腺癌、10例子宫内膜复杂型增生过长及 10例正常子宫内膜组织中TM表达进行检测。结果 TM在子宫内膜腺癌中的表达明显高于子宫内膜复杂型增生过长和正常子宫内膜组织 (P <0 .0 5 )。在子宫内膜腺癌中 ,TM的表达与临床分期有关 ,随分期的升高其阳性表达率降低 (Ⅰ期 76 .5 % ,Ⅱ期 6 3.6 % ,Ⅲ期及其以上者 2 0 %。P <0 .0 5 ) ;而与组织学分级、肌层浸润程度及患者年龄无明显关系 (P >0 .0 5 )。结论 TM表达水平可能与子宫内膜癌的转移有关 ,有望成为判断子宫内膜癌患者病情发展和预后的一项新指标。
Objective To study the expressi on of thrombomodulin (TM) in endometrial carcinoma and explore its relation to the infiltration degree and histological grading of endometrial carcinoma. Methods The expression of TM was detected by immunohistochemistry in 50 cases of endometrial adenocarcinoma, 10 cases of endometrial complex hyper plasia and 10 cases of normal endometrium. Results The posi tive rate of TM in endometrial carcinoma was significantly higher than that in c omplex hyperplasia and normal endometrium (P< 0.05); the expression of TM was gradually decreased with the progress of clinical stage (P< 0.05). A total of 26 out of 34 cases of stageⅠof endometrial carcinoma were positive fo r TM (76.5%), 7 out of 11 cases of stage Ⅱ of endometrial carcinoma were positi ve for TM (63.6%), 1 out of 5 cases of stage Ⅲ of endometrial carcinoma was pos itive for TM (20.0%). However, there were no obvious relationship between the ex pression of TM and the histological grading, muscular invasion and patients' ag e (P> 0.05). Conclusion TM can be used as a new index for judging progre ssion and prognosis of endometrial carcinoma.
