Treatment options for localized recurrence of prostate cancer following radiation therapy

Patients with radioresistant clinically localized prostate cancer may be treated by various means. Although androgen ablation is relatively noninvasive, it cannot be considered a curative option. We believe that a subset of patients with locally recurrent prostate cancer without subclinical metastatic disease exists and would benefit from maximally aggressive local therapy. Salvage surgery may offer long-term cancer control, particularly when the tumor is organ-confined, but is a technically challenging operation with a high incidence of postoperative incontinence. Cryoablation of the prostate for postirradiation recurrence may offer a less invasive alternative to radical surgery, but its long-term efficacy remains to be fully determined. Each therapeutic option has its characteristic attendant morbidity and the choice of therapy for local recurrence should be made with informed consent after frank discussion between physician and patient. We propose the treatment algorithm shown in Figure 1 for the management of patients with suspected recurrence after radiation therapy with the caveat that individual therapeutic strategies must be patterned around individual patient needs.
