摘  要:目的探讨p27^(kip1)、细胞周期素(cydin)E在卵巢上皮性肿瘤中的表达及其与卵巢癌生物学行为的关系。方法采用免疫组化SP法检测卵巢上皮性肿瘤组织中的p27^(kip1)、cyclin E。结果p27^(kip1)蛋白在卵巢上皮性癌和交界性肿瘤中的阳性表达率分别为37.5%、42.11%,显著低于良性肿瘤的78.05%(P均<0.05);cyclin E在卵巢上皮性癌及交界性肿瘤、良性肿瘤的阳性表达率分别为72.22%、47.37%,29.27%,三者相比,P均<0.01。p27^(kip1)、cyclin E在卵巢上皮性癌中的表达与组织分化程度、临床分期有关(P均<0.05)。结论卵巢上皮性癌组织中p27^(kip1)表达下降,cyclin E表达上调,二者在卵巢癌的发生发展过程中发挥重要作用。[ Objective] To investigate expression of p27^(kipl) and cyclin E in ovarian epithelial tumors and its relationship with pathological behavior of ovarian cancer. [ Methods] Expression of p27^(kipl) and cyclin E was determined in ovarian epithelial tumors by using immunohistochemical technique. [ Results ] Expression of p27^(kipl) protein in ovarian epithelial tumors (37.5%) and borderline tumors (42.11%) were significantly lower than that in benign tumors (78.05%) ,P 〈 0.05. There was significant difference of eyelin E expression between ovarian epithelial tumors(72.22% ) and borderline tumors (47.37 % ) , benigh tumors ( 29.27 % ), P 〈 0.01. The expression of p27^(kipl) and cyclin E had a correlation with histological grade and clinical stage( P 〈 0.05 ). [ Conclusion] Expression of p27^(kipl) is reduced and eyelin E is up -regulated in ovarian epithelial tumors ,p27^(kipl) and cyclin E may play important roles in the pathogenesis and progression of ovarian cancer .
