摘要 目的 探讨p53及PCNA表达与膀胱移行细胞癌(TCC)预后的关系。方法 LSAB法检测49例TCC及8例正常膀胱粘膜组织中p53、PCNA表达,分析p53与PCNA表达在TCC中的预后价值。结果 p53在正常膀胱粘膜组织中均为阴性表达,在TCC组织中表达阳性率为40.8%(20/49),两者比较差异有显著性(P<0.05)。p53在T1及T2~4期肿瘤组织中表达阳性率分别为31.4%,64.3%,两者比较差异有显著性(P<0.05);在、、级TCC组织中阳性率分别为13.3%、50.0%、60.0%,组间差异有高度显著性(P<0.01)。p53与PCNA表达呈正相关(P<0.05)。p53阳性表达TCC的复发率、恶性进展率均高于p53阴性表达的TCC(P<0.05)。结论 在TCC中p53表达可作为肿瘤高侵袭力的指标,p53与PCNA正相关。
