增殖细胞核抗原与肺鳞状细胞癌临床病理特征的相关性

目的探讨增殖细胞核抗原(PCNA)在肺鳞状细胞癌(简称)组织中的表达及其与预后的关系.方法51例手术切除的肺鳞癌组织,采用免疫组化(SP)法检测PCNA在不同临床分期及分化程度癌组织中的表达,应用t检验、方差分析(F检验)比较其差异;采用Spearman等级相关分析其相关性.生存率分析采用Kaplan-Meir曲线,Long-Ranktest检验生存期的差异.结果PCNA表达在不同的临床分期及分化程度间差异均显著(P＜0.05).PCNA和临床分期及分化程度与生存期均呈正相关,PCNA指数＞50%组生存期明显短于PCNA指数＜50%组(P＜0.01).结论PCNA在一定程度上可以作为肺鳞癌评价预后的指标.

RELATION BETWEEN THE EXPRESSION OF PROLIFERATING CELL NUCLEAR ANTIGEN AND PROGNOSIS IN LUNG SQUAMOUS CELL CARCINOMA

Objective:To investigate the relation between the expression of proliferating cell nuclear antigen (PCNA) and prognosis in lung squamous cell.Methods:The expression of PCNA on 51 cases carcinoma tissues were detected by immunohistochemical SP technique. Thet test and F test was used to analyze the difference of expression of PCNA in different pathological grades and clinic stages.Spearman Grade-relation test was used to analyze the relation between PCNA expression and pathological grades.The difference of survival time was compared by Kaplan-Meier curve and Long-rank test in different PCNA expression.Rusults:The position of PCNA expression almostl located in the nuclear,some in cytoplasm.There was difference of PCNA expression in different clinical stages and pathological grades.( P <0.05).The survival time of PCNA higher expression is longer than lower expression ( P <0.01).Conclusion:The expression of PCNA can be used to estimate prognosis to some extent.
