We analyzed survivin as a marker of cervical intraepithelial neoplasia (CIN) and high-risk human papillomavirus (HR-HPV) and a predictor of HPV clearance and disease outcome in cervical cancer in 302 samples (squamous cell carcinomas [SCCs], 150; CIN lesions, 152) by immunohistochemical staining with survivin antibody and HPV testing using polymerase chain reaction. HR-HPV types were associated closely with CIN and SCC. There was a significant linear relationship between grade and intensity of survivin expression (P = .0001). Survivin overexpression also was associated strongly with HR-HPV type (P = .0001). Multivariate regression analysis revealed survivin and p16(INK4a) as equally strong independent predictors of HR-HPV. Deregulated survivin expression did not predict clearance or persistence of HR-HPV after treatment of CIN or survival in cervical cancer in univariate (P = .417) or multivariate analysis. After adjustment for HR-HPV, stage, age, and tumor grade in the Cox regression model, only stage (P = .0001) and age (P = .0001) remained independent prognostic predictors. Survivin seems to be an early marker of cervical carcinogenesis. Up-regulated survivin expression was an independent predictor of HR-HPV in cervical lesions, most plausibly explained by its normal transcriptional repression by wild-type p53 being eliminated by HR-HPV E6 oncoprotein.
我们通过使用生存素抗体进行免疫组织化学染色以及采用聚合酶链反应进行人乳头瘤病毒(HPV)检测,对302份样本(150份鳞状细胞癌[SCC]、152份宫颈上皮内瘤变[CIN]病变)中的生存素作为宫颈上皮内瘤变(CIN)和高危型人乳头瘤病毒(HR-HPV)的标志物以及HPV清除和宫颈癌疾病转归的预测指标进行了分析。HR-HPV类型与CIN和SCC密切相关。生存素表达的分级与强度之间存在显著的线性关系(P = .0001)。生存素过表达也与HR-HPV类型密切相关(P = .0001)。多变量回归分析显示生存素和p16(INK4a)是同样强大的HR-HPV独立预测指标。在单变量(P = .417)或多变量分析中,CIN治疗后生存素表达失调并不能预测HR-HPV的清除或持续存在,也不能预测宫颈癌的生存情况。在Cox回归模型中对HR-HPV、分期、年龄和肿瘤分级进行校正后,只有分期(P = .0001)和年龄(P = .0001)仍然是独立的预后预测指标。生存素似乎是宫颈癌发生的早期标志物。生存素表达上调是宫颈病变中HR-HPV的独立预测指标,最合理的解释是野生型p53对其正常的转录抑制作用被HR-HPV E6癌蛋白消除。
