High-dose rate brachytherapy compared with open radical prostatectomy for the treatment of high-risk prostate cancer: 10 year biochemical freedom from relapse
OBJECTIVE: * To compare long-term biochemical control of high-risk prostate cancer in those men receiving high-dose rate brachytherapy (HDRB) and radical prostatectomy (RP). PATIENTS AND METHODS: * The 10-year biochemical freedom from relapse (BFR) was calculated for 243 patients who underwent either RP or combined therapy with HDRB + external beam radiotherapy + androgen deprivation between 1998 and 2000. * Inclusion criteria: clinical stage >/= T2b, or Gleason sum >/= 8, or PSA level of > 20 ng/mL. Groups were appraised using the Kattan nomogram for surgery to calculate progression-free probability (PFP). RESULTS: * For the RP group (153 patients) the median PSA level was 8.1 ng/mL and the median age was 62.2 years. The median 5- and 10-year predicted PFP for RP was 64% and 56 %, respectively. The 5- and 10-year BFR was 65.5% and 55.4%. There was no significant difference between the predicted and the actual PFP for the RP group (P= 0.525). * For HDRB group (90 patients). The median PSA level was 14.2 ng/mL and the median age was 67.6 years. The median 5- and 10-year predicted PFP for HDRB was 46% and 35%, respectively. The 5- and 10-year BFR was 79.6% and 53.6%. There was a significant improvement between the actual and the predicted PFP for the HDRB group (P= 0.002). CONCLUSIONS: * Amongst a high-risk cohort, patients undergoing RP performed as predicted by the pre-treatment surgical nomogram, whereas the patients undergoing HDRB performed significantly better than was predicted by the surgical nomogram at 10 years.
