摘要: 目的 探讨NQO1蛋白在宫颈癌中的表达及其临床意义。方法 免疫组化检测NQO1蛋白在123例宫颈癌标本的表达并比较其与临床病理学参数的相关性,Kaplan-Meier分析NQO1表达对患者无病生存期(DFS)和总生存期(OS)的影响,Cox分析宫颈癌的预后风险因素。结果 NQO1蛋白在宫颈癌中呈胞浆染色,其表达率明显高于正常宫颈组织,且NQO1高表达率与肿瘤组织分化、临床分期、淋巴结转移和HPV感染明显相关;NQO1高表达患者的DFS和OS均明显低于低表达者;NQO1高表达是宫颈癌患者预后不良的独立风险因素。结论 NQO1高表达可能是评估宫颈癌预后不良的生物学指标。

Abstract: Objective To investigate the clinicopathological significance of upregulated NQO1 protein expression in uterine cervix carcinoma(UCC).Methods Immunohistochemical staining was performed on paraffin-embedded UCC specimens from 123 patients.Disease-free survival(DFS)and overall survival(OS)rates for all cervical UCC patients were calculated using the Kaplan-Meier method,and univariate or multivariate analyses were performed using the Cox proportional hazards regression model.Results The NQO1 protein showed a mainly cytoplasmic staining pattern in cervical cancer cells,and the strongly positive rate of NQO1 was significantly higher in UCC.High-level NQO1 was closely associated with poor differentiation,late-stage,lymph node metastasis and high-risk for HPV infection.Additionally,high-level NQO1 was associated with lower DFS and OS rates.Furthermore,Cox analysis revealed that NQO1 expression emerged as a significant independent hazard factor for DFS rate in patients with UCC.Conclusion NQO1 overexpression might be an independent biomarker for prognostic evaluation of UCCs.
