Salvage open radical prostatectomy after failed radiation therapy: a single center experience.

INTRODUCTION

Currently there is no universally accepted approach for the management of radiation-recurrent prostate cancer. The aim of this study was to detail our experience performing salvage radical prostatectomy for patients who failed primary treatment of prostate cancer with radiation therapy.

MATERIAL AND

METHODS

We retrospectively queried our institutional database of radical prostatectomy cases for patients who underwent salvage surgery for radiation-recurrent prostate cancer. Patients were assessed for the risk of complications and oncologic outcomes following salvage surgery.

RESULTS

Twenty-four patients with a mean age of 65 years (range 51-74) underwent salvage radical prostatectomy. Fourteen of these patients (58%) received androgen deprivation therapy prior to surgery. Intraoperatively, mean blood loss was estimated at 415 mL (range 100-1000) and 19 (79%) patients received autologous blood. No patient required an allogeneic transfusion or experienced a rectal injury. Postoperative bladder neck contracture and urinary incontinence developed in 17% and 39% of men, respectively. Two (29%) of seven patients remained potent after salvage surgery. No patient developed a fistula. Overall and recurrence-free survival at 5-years was 90% and 39%, respectively. On multivariate analysis, extracapsular extension was the only significant predictor of biochemical recurrence (HR 6.9, 95% CI 1.9-25.3 p = 0.003).

CONCLUSION

In carefully selected patients, salvage radical prostatectomy for radiation-recurrent prostate cancer is a treatment option with acceptable oncologic outcomes and a moderate complication rate.
