[Treatment of locally advanced prostate cancer]

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.
