The management of clinically locally advanced prostate carcinoma (cT3) remains a controversial issue. The clinical stage cT3 consists of a mixture of overstaged T2 carcinomas but also contains lymph node-positive cases. Treatment options consist of radical prostatectomy, external beam radiotherapy, hormonal deprivation (early or delayed) and the so-called watchful waiting. In many cases multimodal therapy is used. Radical prostatectomy in the clinical stage T3 can achieve acceptable tumour-specific survival rates if patients are well selected. In this way, tumour-specific survival rates can be reached for pT3 patients which closely approach those of pT2 cases. In lymph node-positive cases after radical prostatectomy adjuvant hormonal treatment can prolong survival, but not in lymph node-negative cases. A benefit of adjuvant radiotherapy after radical prostatectomy has not been proven. Although it can postpone or prevent biochemical recurrence, it does not prolong overall survival. Treatment of stage cT3 by external beam radiotherapy alone results in unfavourable tumour-specific survival rates. In these cases definite improvement can be achieved by adjuvant androgen deprivation with LHRH analogues. If in case of severe comorbidity or advanced age primary hormonal treatment is chosen, early vs deferred treatment seems to prolong survival marginally.
临床局部晚期前列腺癌(cT3)的治疗仍是一个有争议的问题。临床分期cT3包括过度分期的T2癌,但也包含淋巴结阳性病例。治疗选择包括根治性前列腺切除术、外照射放疗、激素剥夺(早期或延迟)以及所谓的观察等待。在许多情况下会采用多模式治疗。如果患者选择得当,临床分期T3的根治性前列腺切除术可实现可接受的肿瘤特异性生存率。通过这种方式,pT3患者的肿瘤特异性生存率可以接近pT2病例。根治性前列腺切除术后淋巴结阳性病例辅助激素治疗可延长生存期,但淋巴结阴性病例则不然。根治性前列腺切除术后辅助放疗的益处尚未得到证实。虽然它可以推迟或预防生化复发,但并不能延长总生存期。单纯采用外照射放疗治疗cT3期会导致不良的肿瘤特异性生存率。在这些情况下,使用促性腺激素释放激素(LHRH)类似物进行辅助雄激素剥夺可实现明确改善。如果因严重合并症或高龄而选择初始激素治疗,早期治疗与延迟治疗相比似乎能略微延长生存期。
