Hormonal manipulation for rising PSA after radical prostatectomy

Abstract

PSA recurrence after radical prostatectomy usually indicates recurrent prostate cancer. Identification of the recurrence site is difficult, but pathological and clinical features may suggest local versus distant recurrence. Radiographic techniques including transrectal ultrasonography, and 111indium capromab pendetide scans may help identify recurrences. The use of hormonal manipulation for rising PSA after radical prostatectomy is controversial. Androgen deprivation has been a mainstay of the management for advanced prostate cancer. The timing of such therapy is debatable, and early therapy in an asymptomatic patient may not correlate with improved survival. Maximal androgenic blockade with castration and nonsteroidal antiandrogens may offer a modest survival benefit in selected patients. Novel potency-sparing therapies with antiandrogens and finasteride afford an improved patient lifestyle, with questionable effects on survival. Intermittent androgen suppression is an experimental treatment modality that may reduce the side effects of castration. Ongoing studies are being performed to clarify these controversies, and the variety of treatment options allows patients great flexibility in considering quality of life and effective cancer control.
