摘要 目的探讨抑癌基因PTEN及增殖细胞核抗原(PCNA)在子宫内膜癌中的表达及临床意义。方法应用免疫组化SP法检测PTEN和PCNA在18例正常增生期子宫内膜(正常组)、21例子宫内膜不典型增生(癌前病变组)和22例子宫内膜腺癌(内膜癌组)中的表达。结果正常组、癌前病变组及内膜癌组PCNA表达分别为61.1%(11/18)、71.4%(15/21)和95.5%(21/22),3组间比较,差异有统计学意义(P<0.05);各组子宫内膜组织中PTEN表达分别为:正常组88.9%(16/18)、癌前病变组71.4%(15/21)、内膜癌组27.3%(6/22),3组间比较,差异有统计学意义(P<0.05)。结论PCNA表达增强可能是子宫内膜癌在分子水平上的早期变化,PTEN表达减弱可能与子宫内膜腺癌的发生、发展密切相关,二者对早期诊断子宫内膜癌有一定意义。 Objective To study the expression and clinical significance of proliferating cell nuclear antigen (PCNA) and PTEN in endometrial carcinoma. Methods The expression of PTEN and PCNA of 18 cases of proliferative endometrium (normal group), 21 cases of atypical hyperplasia of endometrium (precancerous lesion group), and 22 cases of endometrial carcinoma ( endometrial carcinoma group ) was determined immunohistoehemically (SP method). Results PCNA expression in the normal group (16. 1%), precancerous lesion group (71.4% ), and endometrial carcinoma group ( 95.5 % ) was significantly different ( P 〈 0.05 ) ; PTEN expression in the endometrial carcinoma group (27.3%, 6/22) was significantly lower than that in the normal group (88.9%, 16/18) and precancerous lesion group (71.4%, 15/21) (P〈0.05). Conclusion Increase of PCNA expression may be one of the molecular manifestations in the early stage of endometrial carcinoma while decrease of PTEN expression may be involved in carcinogenesis and development. This may contribute to early diagnosis of endometrial carcinoma.
