[Cancer of the prostate: curative radiotherapy preceded by lymphadenectomy in 20 patients. Follow-up over 10 years].

Twenty patients with prostatic cancer were treated by external beam radiotherapy after ilioobturator lymphadenectomy. The patients could be divided into two groups: Group I: no lymph node invasion and Group II: presence of lymph node metastases. In Group I, only one death was due to cancer and the 6-year survival was 90%. In Group II, 7 deaths were due to cancer and the 6-year survival was 20%. Secondary endocrine treated administered at the time of recurrence appeared to significantly prolong survival in comparison with the stage D1 cancers treated immediately by endocrine therapy.
