Evaluation of the residual prostate cancer rate on cystoprostatectomy specimen in patients treated with radiotherapy for prostate cancer.

Purpose: To evaluate the residual cancer rate after cystoprostatectomy (CPT) in patients with a history of radiation therapy for prostate cancer and the postoperative complication rates.

Material And Methods: We conducted a retrospective study involving 21 patients who had a CPT over 7 years and who had a history of radiotherapy for prostate cancer. To compare results, two additional groups were created: a group of patients without a history of radiotherapy in whom a CPT was performed, and a group without a history of radiotherapy and in whom was accidentally discovered a prostate cancer after CPT on histology specimens.
