摘    要:目的探讨PLK1在子宫内膜癌组织中的表达,及其表达与子宫内膜癌临床病理因素和预后的关系。方法采用免疫组化S—P法检测PLK1在子宫内膜癌组织中的表达,并分析其表达与子宫内膜癌临床病理因素间的关系和对预后的影响。结果PLK1在子宫内膜癌组织中的阳性表达率为18.0%,主要呈胞浆染色。PLK1表达与子宫内膜癌的FIGO分期(P=0.04)和肿瘤细胞的分级(P=0.01)密切相关,与肿瘤复发转移(P=0.07)介于临界状态。PLK1阳性表达者的5年生存率明显低于阴性表达者(67.2%VS.82.4%,P=0.076),但二者差异介于临界状态。COX分析显示PLK1表达不是子宫内膜癌患者的独立预后指标(P=0.761)。结论PLK1在子宫内膜组织中呈高表达,可作为肿瘤细胞增殖和分化程度的标志物,且可能成为子宫内膜癌预后的潜在标志物,但需进一步严格分层研究。

Abstract:Objective To explore the expression of PLK1 protein and its associations with clinicopathologic factors and prognosis in endometrial carcinoma of uterine.Methods Expression of PLK1 was investigated by S-P immunohistochemistry. The relations of PLK1 expression with clinicopathologic factors and its effect on prognosis of endometrial carcinoma were evaluated by X~2(Fisher's exact) test and univariated or multivariated survival analysis.Results The positive expression of PLK1 was located in cytoplasma of carci...
