Abstract： 目的探讨自发凋亡率、p27kip1在人膀胱移行细胞癌中表达的临床意义.方法采用TUNEL法检测自发凋亡细胞,用S-P法检测p27kip1基因在50例膀胱移行细胞癌中的表达,分析各检测指标在上述标本中的表达及与膀胱移行细胞癌分级、临床分期间的关系.结果在膀胱移行细胞癌中,自发凋亡率AI均数为(3.0±1.5)%,p27kip1基因的阳性表达率为58.0%(29/50).其二者的阳性表达均随膀胱癌分级、分期的升高而降低.p27kip1蛋白阳性组中AI均数显著高于p27kip1蛋白阴性组(P＜0.05).结论p27kip1蛋白和自发凋亡率与肿瘤的恶性程度和进展密切相关,联合检测p27kip1和自发凋亡率有助于更准确地解释和描述膀胱癌的生物学行为.
