We evaluated the effect of neoadjuvant hormonal therapy on urinary function in men with a prostate volume of 50 cc or greater undergoing prostate brachytherapy.


A total of 395 men with 50 cc or greater glands were treated with 3 months of neoadjuvant hormonal therapy (204) or implantation alone (191). Urinary function was assessed by the International Prostate Symptom Score, the urinary retention incidence and subsequent transurethral prostate resection.


Median patient age was 67 years and median followup was 6 years. Mean prostate volume in neoadjuvant hormonal therapy cases was 72.9 cc, which decreased to 54.3 cc after 3 months (p <0.001). Mean prostate volume in cases without hormonal therapy was 60.6 cc (p <0.001). Urinary retention occurred in 16 of 191 men (8.4%) without vs 25 of 204 (12.3%) with hormonal therapy (p = 0.207). The median duration of urinary retention was 42 days (range 2 to 243). There were no significant associations of urinary retention with prostate size, prostate or urethral dose, or pre-implantation International Prostate Symptom Score. Of patients without hormonal therapy retention occurred in 3 of 12 (25%) with a pre-implantation International Prostate Symptom Score of 15 or greater and in 13 of 168 (7.7%) with a score of less than 15 (OR 4.0, 95% CI 1-16, p = 0.04). In contrast, there was no difference in the retention rate in patients with hormonal therapy with an initial score of 15 or greater vs less than 15 (2 of 25 or 8% vs 11 of 102 or 10.8%, p = 0.614). Transurethral prostate resection was done in 11 of 191 men (5.8%) without vs 12 of 204 (5.9%) with hormonal therapy (p = 0.958). There was no difference in biochemical failure in the 2 groups.


Neoadjuvant hormonal therapy has its greatest benefit in patients receiving brachytherapy who have a large prostate and an International Prostate Symptom Score of 15 or greater.
