Management of asymptomatic rising PSA after prostatectomy or radiation therapy.

Controversy exists over the optimal management of patients with an asymptomatic rising prostate-specific antigen (PSA) following definitive therapy for clinically localized prostate adenocarcinoma. Post-prostatectomy patients whose residual disease is felt to be confined to the area immediately adjacent to the prostatic bed may benefit from external-beam radiation therapy. Systemic recurrence may be managed with either watchful waiting or treated with hormone deprivation. Post-radiation therapy patients felt to have local disease progression may undergo salvage radical prostatectomy (if disease is clinically confined to the prostate gland) or cryotherapy (although this is still considered "experimental"). Patients who are not candidates for salvage therapy can be managed with watchful waiting or hormone deprivation. For patients in whom definitive therapy has failed, treatment should be individualized according to pathologic stage (if post-prostatectomy), rate of PSA progression, surgical candidacy status (if post-radiation therapy), and attitudes and expectations of the physician and patient.
