SALVAGE RADICAL PROSTATECTOMY AFTER FAILURE OF CURATIVE RADIOTHERAPY FOR ADENOCARCINOMA OF PROSTATE

Radical prostatectomy with curative intent was performed in 13 patients with prostate cancer after local failure of radiotherapy. Of these patients, 2 underwent cystoprostatectomy for bladder neck involvement by the prostatic tumor. Local recurrence had been diagnosed twenty-one to one hundred sixty-eight months (mean 65.4 months) after completion of radiotherapy (6,000-7,000 cGy; mean 6,136 cGy). Three patients had radioactive implants. Rising prostate-specific antigen (PSA) was part of the indication for surgery in 5 patients. Complications included minor rectal injury (1 patient) and total incontinence (2113 patients). Two patients had positive surgical margins and 6113 patients had involvement of seminal vesicles, 2 of whom also had positive lymph nodes. The authors conclude that salvage prostatectomy is feasible after radiation failure. Transrectal ultrasound and careful monitoring of PSA after irradiation treatment may improve patient selection and minimize the risk of complications and incomplete excision.
