title: Postoperative irradiation in carcinoma of the prostate.
abstract: Twenty-eight patients received postoperative radiotherapy with curative intent following either radical prostatectomy (18 patients) or enucleative prostatectomy (10 patients). In patients undergoing radical prostatectomy, the indications for postoperative radiotherapy included positive margins in 13, "close" margins in 2, and seminal vesicle involvement in 3 patients. The majority of patients (82%) received total dose to the prostatic bed in excess of 6500 rad. In over 80% of the patients, the pelvic lymphatics are also treated (to a total dose of 4000-5000 rad). Minimum follow-up is one year, maximum is 10 years, average 54 months, median 41 months. Local recurrence was observed in only 1 patient, who was treated post-enucleation. All of the patients irradiated after radical prostatectomy clinically remained disease-free locally. Approximately one-half of the patients in both the enucleation and radial prostatectomy groups developed evidence of distant metastases. The complications of treatment have been comparable to those in patients treated with radiotherapy only. The continence status has not been affected significantly. All patients (5 in the radical prostatectomy group and 2 in the enucleation group) with incontinence following completion of radiotherapy had documented impairment of continence prior to radiotherapy. Postoperative radiotherapy administered following either radical or enucleative prostatectomy was tolerated well and resulted in excellent local control.
