摘要: 目的:研究细胞周期相关蛋白P53和核蛋白抗原Ki67在口腔鳞癌组织中的表达及其与预后的相关性,寻找预后判断的有效生物标志物。方法:用免疫组织化学EnVision染色法的方法检测随访资料完整的132例口腔鳞癌患者术后石蜡切片中P53、Ki67蛋白的表达,研究口腔鳞癌组织中P53、Ki67与病理特征的相关性及口腔鳞癌预后的相关性。结果:132例口腔鳞癌标本蛋白检测和统计分析结果表明,P53和Ki-67蛋白在口腔鳞癌中的高表达与患者细胞分化程度,肿瘤T分期和肿瘤原发灶有关(P<0.05);P53蛋白的表达水平与口腔鳞癌术后生存率呈显著的相关性(P<0.05);Ki67蛋白的表达水平与口腔鳞癌术后生存时间并无显著的相关性。结论:口腔鳞癌患者癌组织标本的P53表达水平与预后呈正相关,P53有望成为口腔鳞癌预后判断的间接性生物标志物。

Abstract: Objective: To investigate the expression of p53 and ki67 proteins, and their relations to prognosis of patients in oral squamous cell carcinoma (OSCC). Methods: A retrospective study including 132 patients with OSCC was performed, and the follow-up time was at least 5 years. The expression levels of p53 and ki67 were detected by immunohistochemistry and analyzed for the correlation with pathological features and prognosis of patients in OSCC. Results: The expression levels of p53 and ki67 correlated with cell differentiation, TNM stages and tumor site in OSCC (P<0.05). In addition, the expression of p53 was an independent prognostic parameter in patients with OSCC (P<0.05), but ki67 expression was not. Conclusion: The expression level of p53 is an effective biomarker and an independent prognostic parameter in oral squamous cell carcinoma
