Background: How best to treat rising prostate-specific antigen (PSA) concentration after radical prostatectomy is an urgent clinical question. Salvage radiotherapy delays the need for more aggressive treatment such as long-term androgen suppression, but fewer than half of patients benefit from it. We aimed to establish the effect of adding short-term androgen suppression at the time of salvage radiotherapy on biochemical outcome and overall survival in men with rising PSA following radical prostatectomy.

Background And Purpose: We evaluate the feasibility of concomitant and adjuvant docetaxel combined with three-dimensional conformal radiotherapy (3D-CRT) and androgen deprivation in high-risk prostate carcinomas.
Methods: Fifty men with high-risk localized prostate cancer (16), locally advanced (28) or very high-risk prostate cancer (6) were included. Seventy Gy were delivered on prostate and seminal vesicles in 35 fractions, concurrently with weekly docetaxel (20mg/m(2)).
RTOG and EORTC trials have paved the way of the combination of radiation therapy and androgen suppression. Localized carcinoma with intermediate prognostic factors (cT2b, Gleason 7, or baseline PSA ranging between 10 and 20 ng/mL) may be submitted to a 4-month complete androgene blockade with 2 months before irradiation, unless to include patients in ongoing randomized trials. High risk cancers (cT2c, or Gleason > 7, or PSA > 20 ng/ml) should receive a 4-month or 6-month complete androgen blockade (RTOG trial 86-10), knowing that the results of EORTC trial 22961 are eagerly expected to tell us whether a 3- year androgen suppression is preferable.

Complete androgen blockade initiated 2 months prior to starting radiotherapy and stopped at the completion of radiotherapy vs radiation therapy alone, increased overall survival in patients with Gleason score 2-6. Adjuvant androgen suppression started at the end of the radiotherapy and continued indefinitely improved significantly overall survival of patients Gleason score 8 to 10.
