摘要 目的观察膀胱癌伴前列腺癌(concomitant bladder neoplasm and prostate cancer,CBP)的临床病理学特征,以提高前列腺癌的检出率。方法回顾性分析199例膀胱前列腺切除标本中11例CBP的临床资料、病理学特征及免疫表型,对患者进行随访,并复习相关文献。结果 CBP发生率为5. 5%(11/199),其中临床期前列腺癌5例(2. 5%),偶发性前列腺癌(incidental prostate cancer,IPCa) 6例(3. 0%)。患者年龄58~87岁,平均(74. 3±7. 04)岁,5例(45. 4%)患者术前行前列腺MRI检查,均提示异常。膀胱癌特点:10例(90. 9%)为高级别浸润性尿路上皮癌,1例(9. 1%)为膀胱腺癌,其中1例高级别尿路上皮癌伴腺样分化。4例(36. 4%) p T1期,5例(45. 4%) p T2期,2例(18. 2%) p T3期。前列腺癌特点:11例(100%)均为经典型前列腺腺泡癌; Gleason评分分组:1组9例(81. 8%),2组1例(11. 1%),4组1例(11. 1%);肿瘤分期:p T1期1例(9. 1%),p T2期10例(90. 9%)。免疫表型:11例前列腺腺癌AMACR均(+),HMWCK和p63均(-)。平均随访75. 2个月(24~195个月),2例失访,1例死亡,其余8例均健在。结论在膀胱前列腺切除标本中,取材方法对前列腺癌的检出率有重要影响,术前MRI检查有助于提高前列腺癌的检出率。另外,膀胱癌较前列腺癌对预后影响更大。
