Purpose:

RATIONALE: Sildenafil citrate and alprostadil may help patients who have undergone prostatectomy for prostate cancer to recover from erectile dysfunction. PURPOSE: This randomized clinical trial is studying giving sildenafil together with alprostadil in treating patients undergoing nerve-sparing robotic-assisted radical prostatectomy for nonmetastatic prostate cancer.


Study summary:

PRIMARY OBJECTIVES: I. To determine the rate of erectile function (defined as the ability to achieve and maintain an erection sufficient for intercourse without the use of pharmacological assistance) at 1 year post-operatively in men undergoing BNS-RAP without the use of post-operative maintenance pharmacotherapy. II. To describe whether early post-operative maintenance pharmacotherapy Viagra can improve return of erectile function at 1 year post-operatively in patients undergoing BNS-RAP. III. To describe if early post-operative maintenance pharmacotherapy Viagra can decrease the time-to-return of erectile function in patients undergoing BNS-RAP. SECONDARY OBJECTIVES: I. To describe whether early post-operative maintenance pharmacotherapy MUSE can improve return of erectile function at 1 year post-operatively in patients undergoing BNS-RAP. II. To describe if early post-operative maintenance pharmacotherapy MUSE can decrease the time-to-return of erectile function in patients undergoing BNS-RAP. III. To compare sexual function quality of life in men undergoing early post-operative maintenance pharmacotherapy to those without early post-operative maintenance pharmacotherapy. IV. To compare the rate of potency at 1, 3, 6, 9, 12, and 18 months in men using Viagra versus MUSE for early post-operative maintenance pharmacotherapy. V. To describe the dropout rate for MUSE maintenance pharmacotherapy secondary to urethral pain in men using 2% Lidocaine lubricant. VI. To describe if penile length is decreased following BNS-RAP. VII. To describe if penile length at one year is different in men who have return of potency versus those with no return of potency. OUTLINE: Patients receive 2 doses of intraurethral alprostadil prior to undergoing bilateral nerve-sparing robotic-assisted prostatectomy. Within 4 weeks after surgery, patients are randomized to 1 of 3 treatment arms. ARM I: Patients receive intraurethral alprostadil once daily for up to 9 months in the absence of disease progression or unacceptable toxicity. Patients also receive 3 doses of oral sildenafil citrate at least 48 hours apart monthly for up to 18 months. ARM II: Patients receive 3 doses of oral sildenafil citrate on 3 separate occasions at least 48 hours apart monthly for 18 months. ARM III: Patients receive oral sildenafil citrate once daily for up to 9 months in the absence of disease progression or unacceptable toxicity. Patients also receive 3 doses of oral sildenafil citrate at least 48 hours apart monthly for up to 18 months. After completion of study treatment, patients are followed periodically for up to 18 months.
