摘要 目的探讨P504s、Ki-67、34βE12抗体在良性前列腺增生(BPH)、高级别前列腺上皮内瘤(HGPIN)及前列腺腺癌(PAC)组织中的表达及临床意义。方法收集BPH和HGPIN和PAC病理标本各30例,按常规方法石蜡包埋制作蜡块连续切片,进行HE染色及P504s抗体、Ki-67抗体、34βE12免疫组织化学染色。结果 P504s的阳性表达率在PAC组织中明显高于HGPIN及BPH组织。Ki-67表达阳性率及增殖指数在PAC组织中明显高于HGPIN及BPH,且随着Gleason分级增高其增殖指数存在增高的趋势。34βE12表达在良性前列腺增生、高级别前列腺上皮内瘤中基底膜表达阳性,在前列腺恶性瘤中无基底膜表达。结论 P504s、Ki-67及34βE12在不同病变中表达不同,可用于前列腺良、恶性疾病的诊断、鉴别诊断及预后的判断。
