目的总结睾丸精原细胞瘤的远期疗效并探讨其治疗策略。方法回顾性分析294例睾丸精原细胞瘤患者的临床资料。按1997年国际抗癌联盟（UICC）的TNM分期标准，Ⅰ期260例，Ⅱ期16例，Ⅲ期18例。治疗方法为手术切除原发病灶联合化疗和（或）放疗。数据分析采用SPSS13．0统计软件，生存分析应用Kaplan—Meier法，总生存率的比较采用Logrank方法检验。结果全组294例患者的5、10、20和30年总生存率分别为92．1％、91．8％、85．5％和71．4％。临床分期对总生存率有显著影响。I期患者中，术后辅助治疗者与未行辅助治疗者的10年总生存率分别为97．5％和79．2％，经辅助治疗者的生存明显获益（P=0．001）。Ⅱ期和Ⅲ期患者的预后均与治疗方法无关（均P〉0．05）。结论睾丸精原细胞瘤对放化疗敏感，即使出现复发转移的患者仍有长期生存可能。治疗时应充分考虑患者的生活质量，尽量避免大范围手术切除和长期化疗。
