The greatest obstacle in the cure of patients with locally recurrent prostate cancer after radiation therapy is the lack of early detection markers. The majority of patients who are candidates for local salvage therapy have locally advanced disease, precluding successful salvage therapy. A low pretreatment prostate specific antigen (PSA) has shown to be a favorable prognostic variable for disease progression, regardless of the specific local salvage therapy used. Of all the local salvage treatment options for these patients, we believe that salvage radical prostatectomy (RP) offers patients the great-est likelihood of a cure. The salvage RP results approach those achieved with standard RP for patients of similar pathologic stage. When patients are treated early in the course of recurrent disease (preoperative PSA < 10 ng/mL), an estimated two-thirds of patients will be disease-free 5 years after salvage RP alone. With better patient selec-tion and continued technical modifications, the morbidity associated with salvage RP has substantially improved. Perioperative complications approach those observed with standard RP and approximately two-thirds of patients will recover urinary continence. Select patients may also recover functional erections when nerve-sparing techniques are used. Salvage cryotherapy and brachytherapy are minimally invasive alternatives to salvage RP. The cancer control results of these procedures appear to be inferior to results achieved with salvage RP. Each of these procedures is associated with signifi-cant morbidity and do not appear to provide a clear advantage over salvage RP in terms of posttreatment complications, urinary continence, and erectile function. A long-term cure is possible for patients with locally recurrent prostate cancer after radiation therapy. Local salvage therapy must be instituted early to be successful in the course of progressive disease.
