title: [Adjuvant radiotherapy after radical prostatectomy. Apropos of a series of 73 patients in Lyons (France)].
abstract: OBJECTIVE
  Descriptive analysis of adjuvant radiation therapy after radical prostatectomy.
  
  
  METHODS
  From 1986 to 1993, 73 patients (median age, 64.5 years; Gleason score > or = 7 : 36 pts; T1:22; T2:40; T3:11) were included into the study. On the operative specimen, the cancer grades were pT2:5 (involvement of the apex), pT3:67, pT4:1, pN1-2:8. Radiation therapy was performed after a mean resting period of 112 days. The target volume was the prostatic area. The technique used was a four-field box with an 18 MV-X photon beam. The dose was 50 Gy/20 fractions/5 weeks. No hormonal treatment was administered, except for 5 patients for a short duration.
  
  
  RESULTS
  The median follow up was 46 months. One anastomotic local failure was salvaged by trans-urethral resection, three distant metastatic failures. Out of 72 patients with a PSA < 3 ng/mL at the end of radiotherapy, 13 showed an isolated elevation. The 5-year overall survival rate was 93%. The event-free survival was 72% after 5 years. Pathological differentiation and Gleason score were significantly correlated with the survival. There was no complication related to radiotherapy.
  
  
  CONCLUSIONS
  Elective adjuvant radiation therapy for pT3 prostate adenocarcinoma after radical prostatectomy provides a good local control with minimal morbidity.
