Abstract

Purpose: We determined whether 12 weeks of neoadjuvant testicular androgen ablation therapy using a luteinizing hormone-re]easing hormone agonist could improve pathological outcomes in men undergoing radical retropubic prostatectomy for clinically localized (stages T1C, T2A and T2B) prostatic carcinoma. Materials and Methods: A total of 56 participants was randomized to receive either monthly injections of a luteinizing hormone-releasing hormone agonist at 4-week intervals followed by radical retropubic prostatectomy (28) or to undergo immediate radical retropubic prostatectomy alone (28). Operations were performed via a similar technique and all prostatic specimens were processed histologically in their entirety. Results: There was no improvement in pathological outcome using a luteinizing hormone- releasing hormone agonist preoperatively compared to surgery alone. Of 28 men undergoing immediate radical retropubic prostatectomy 23 had organ-confined (17) or specimen-confined (6) disease versus 22 of 28 who received luteinizing hormone-releasing hormone neoadjuvant therapy for 12 weeks preoperatively (16 with organ-confined and 6 with specimen-confined disease, p = 1.00). In addition, when the study population was analyzed by pretreatment prostate specific antigen (PSA) levels (10 ng./ml. or less, or greater than 10 ng./ml.) there was also no difference in pathological outcome (p 0.65 for PSA greater than 10 and p 0.32 for PSA less than 10). Conclusions: Neoadjuvant androgen ablation therapy for 12 weeks before radical prostatectomy in patients with clinically localized adenocarcinoma of the prostate does not result in improved pathological outcomes.
