Treatment Of Erectile Dysfunction In Patients Treated On RTOG-9910 For Prostate Cancer: Impact On Patient And Partner Quality Of Life
- Compare the effect of sildenafil vs placebo on erectile dysfunction in patients with
prostate cancer treated with radiotherapy and antiandrogens on RTOG-9910.
- Compare the overall sexual function and satisfaction of patients treated with these
- Compare sexual satisfaction of partners of patients treated with these regimens.
- Compare patient and partner marital adjustment after treatment with these regimens.
- Determine factors that may predict response to sildenafil, including age, pretreatment
sexual function, tobacco use, and comorbidities in these patients.
OUTLINE: This is a randomized, placebo-controlled, multicenter study. Patients are
stratified according to prior use of sildenafil after treatment on RTOG-9910 and level of
response (No vs yes [unsatisfactory] vs yes [satisfactory]), International Index of Erectile
Function Question #1 score (0-1 vs 2-3), and RTOG-9910 treatment arm (I vs II). Patients are
randomized to 1 of 2 treatment arms.
- Arm I: Patients receive oral sildenafil 1 hour prior to desired sexual intercourse.
- Arm II: Patients receive oral placebo 1 hour prior to desired sexual intercourse.
Treatment on both arms continues for 12 weeks. Patients then cross over to treatment on the
other arm for 12 weeks.
Quality of life, including sexual function, marital adjustment, and partner's satisfaction,
is assessed at baseline, at 12 and 25 weeks, and at 1 year.
Patients are followed at 1 year.
PROJECTED ACCRUAL: A total of 332 patients (166 per treatment arm) will be accrued for this
Allocation: Randomized, Primary Purpose: Supportive Care
