摘要 目的:探讨非浸润性前列腺移行细胞癌(PTCC)的病理以及诊治。方法:结合文献复习,回顾分析6例PTCC的临床资料。6例年龄67~74岁,平均71岁。3例表现为无痛性间歇性血尿和排尿困难,有BPH史,经系统检查术前诊断为多发性浅表性膀胱癌和BPH,行经尿道膀胱肿瘤电切(TURBT)加经尿道前列腺电切术(TURP);1例尿频尿急血尿,经膀胱镜检查并活检诊断为膀胱原位癌(Tis)G3,行根治性膀胱前列腺切除(Briker术);1例诊断BPH,行TURP;1例有2次膀胱癌手术史,进行性排尿困难,前列腺质硬,诊断为膀胱颈挛缩,行TUR切除膀胱颈及前列腺。所有病例术前的临床表现、生化及影像学检查均未提示前列腺肿瘤。结果:3例TURBT加TURP者膀胱病理为移行细胞癌(TCC)P1aG2、P1bG2、P1bG2,前列腺标本中发现前列腺导管内TCC细胞簇未穿透管壁,随访3~5年,其中1例死于脑出血,1例膀胱癌复发再次TURBT;经Briker术者膀胱病理为PisG3,前列腺导管内非侵润性移行细胞癌,随访7年无癌生存;1例TURP后病理发现PTCC,膀胱镜随访,于术后10周发现膀胱多发性TCCG3,拒绝再次手术,1年后死亡;有膀胱癌史者的TUR标本发现TCC已穿透前列腺导管侵犯基质,2月后发现肝脏转移而于术后5月死亡。本组6例PTCC均因术后病理而诊断,占本院同期所有TCC的1.9%。结论:PTCC多与膀胱癌伴发,早期因无特征性临床表现和生化、影象学提示而容易漏诊。病理是目前唯一的诊断途径。危险因素包括:①高级别膀胱TCC;②多发性膀胱TCC;③膀胱Tis。相比前列腺穿刺活检,TUR获取的组织标本阳性率高。根治性膀胱前列腺切除疗效肯定,TURP亦可作为治疗PTCC的有效手段。
