[Carcinoma of the prostate as a late complication of prostatectomy]

In 8 patients after removal of a benign adenoma of the prostate (4 enucleations, 4 transurethralresections) 4-12 years later carcinoma of the prostate developed. In 2 cases bonemetastases were already present. The patients returned with obstructive problems and were resected transurethrally, once more. After the histological examinations the postoperative treatment consisted of subcapsular orchidectomy followed by Oestrogen-therapy. It seems that the incidence of carcinoma of the prostate after removing of a benign adenoma is less frequent than expected from the frequency of carcinoma. It is recommended to follow the patients for years and to inform them of this possible development.
