Forty-nine patients with localized carcinoma of the prostate were treated by external radiotherapy together with hormonal manipulation and were followed up to six years. Hormonal manipulation included bilateral orchiectomy and diethylstilbestrol, 3 mg/day. The cumulative five-year survival for the 49 patients was 87.6%, with 11 % progression rate to stage D during that period. In 40 patients (81.6%), a decrease in the size of the prostate was noted. In none of the patients was there local recurrence of the tumor during the period of follow-up. Transient gastrointestinal and/or urinary symptoms occurred following radiotherapy in 11 patients (22.4%), and in four patients severe cystitis or proctitis appeared. Complications related to hormonal therapy occurred in 11 patients (22.4%). The high survival rates reported herein, together with the low progression rate to stage D during six years of follow-up, may justify the early institution of radiotherapy in combination with hormonal manipulation for patients with localized carcinoma of the prostate. A randomized study with an extended number of patients is underway to further evaluate this mode of therapy. |
