There are currently several clinical trials underway for treatment of
erectile dysfunction (ED) for men who have prostate cancer:
One trial is comparing the effectiveness of nerve-sparing
prostatectomy (surgical removal of all of the prostate and preservation of
the erection-controlling nerves), with and without nerve grafting, followed
by standard therapy. The patients will be in one of two groups: the first
group will have nerve-sparing prostatectomy with nerve grafting, then will
use a standard therapy such as Viagra, a vacuum erection device, injection
therapy, or MUSE (suppository in urethra for erections) therapy. The
patients in the second group will have the nerve-sparing surgery without the
nerve grafting, and will use the same standard therapy as the first group.
The objectives of the study are to compare the two types of surgery for
effectiveness and their effects on potency rates and erection quality in men
with prostate cancer.
In the second trial and third trials, researchers are examining
the effectiveness of erectile dysfunction treatment with Viagra versus a
placebo (sugar pill) for men with prostate cancer who have undergone
radiation therapy and total androgen suppression. The studies are attempting
to determine if there is a difference in overall sexual function and
satisfaction between Viagra and placebo.
