Abstract
This retrospective study describes three clinically different groups of patients with symptomatic androgen-independent prostate cancer (AIPC) referred to palliative radiotherapy (RT): those with a symptomatic pelvic tumour and pelvis-confined disease (M0 P-RT: 35 patients), those with a symptomatic pelvic tumour and distant metastases (M+ P-RT: 97 patients) and those with painful bone metastases (BM-RT: 193 patients). The study emphasises the need of a combined surgical and radiotherapeutic palliation in AIPC patients with symptomatic pelvic tumours. Median overall survival from time of palliative RT was 19, 9 and 8 months for M0 P-RT, M+ P-RT and BM-RT patients, respectively (p<0.001). The significantly prolonged natural course of P-RT patients without distant metastases has to be accounted for in clinical trials of AIPC patients in whom survival represents an endpoint. Furthermore, the optimal palliation regimens for P-RT patients are still to be defined.
