摘要 目的探讨高迁移率组蛋白A2(HMGA2)在膀胱尿路上皮癌中的表达与临床病理特征及复发的关系。方法选择膀胱尿路上皮癌病理组织标本49例,正常膀胱组织标本5例,通过免疫组化方法检测两组标本中HMGA2蛋白的表达。结果在正常膀胱组织中HMGA2蛋白未见表达,在膀胱癌组织中HMGA2蛋白的表达随着临床分期及病理分级的升高而增加。在Ta、T1、T2膀胱癌中HMGA2蛋白表达的阳性率分别为20%、47.6%、75%,差异有统计学意义(P<0.05)。在低级别、高级别膀胱癌组织中HMGA2蛋白表达阳性率分别为25%、56%,差异有统计学意义(P<0.05)。术后随访18~40个月,42例中复发18例,HMGA2蛋白在复发组与未复发组中阳性表达率分别为62.5%、30.8%,差异有统计学意义(P<0.05)。另外,HMGA2蛋白的表达与肿瘤的大小、性别、年龄无关(P>0.05)。结论在膀胱癌组织中HMGA2蛋白的表达明显高于正常膀胱组织,且与肿瘤的分期、分级及复发有关;HMGA2蛋白可以作为评价膀胱肿瘤进展和预后的一个潜在指标。
