Popis: To compare the impact of bicalutamide (B) vs. luteinizing hormone-releasing hormone analogues (LHRHa) on prostate volume, patient-reported side effects, and postimplant urinary toxicity in the setting of interstitial brachytherapy for early-stage prostate cancer.Between May 1998 and January 2004, 81 patients received androgen-deprivation therapy (ADT) for cytoreduction prior to interstitial brachytherapy alone. Fifty-six patients received LHRHa and 25 patients received B. Prostate volumes were measured prospectively prior to initiating therapy, and then intraoperatively at the time of implant by a single, blinded ultrasonographer. Patient-reported quality of life data were obtained prospectively, and postimplant urinary toxicity (catheter dependency and need for surgical intervention) was recorded during follow-up. Median follow-up was 53 (range 23-78) months.The median percentage prostate volume reductions of 26% for B and 32% for LHRHa were not statistically different (P = 0.61). Decrements in libido (92% vs. 44%, P0.001) and erectile function (79% vs. 20%) were reported in more respondents treated with LHRHa than B. The incidence of recatheterization (28% vs. 24%, P = 0.34), and the need for subsequent surgical intervention (11% vs. 4%, P = 0.16) were similar for patients treated with LHRHa and B.The degree of prostate downsizing with B is similar to that achieved with LHRHa. B was associated with fewer patient-reported sexual side effects and similar urinary morbidity. A randomized trial is needed to establish whether LHRHa or B should be the standard of care for prostate downsizing before interstitial brachytherapy.
