The primary objective was to evaluate the PSA (biochemical) progression-free survival (PFS) of high-risk metastasis-free PC patients, treated with LH-RH agonist for one year with or without docetaxel after prior radical prostatectomy (RP) or radiotherapy (RT).

The study was powered at 80% to detect a 25% improvement in biochemical PFS for a total sample size estimated at 252 patients, with a two-sided type I error rate of 5% (non-parametric methods.
Docetaxel was shown to be active in metastatic hormone-refractory prostate cancer (PC) in phase III trials (1-2). It is likely to demonstrate a substantial role in the management of early-stage PC patients in the neoadjuvant and adjuvant settings, where clinical trials are underway.•53% of all men who undergo radical prostatectomy will develop prostate-specific antigen (PSA) elevations in the 10 years following surgery, with approximately 77% of these recurrences occurring within the first 2 years.A prospective, multicenter, national, randomized, two-arm, phase III study comparing hormonal treatment (LH-RH agonist alone) with or without docetaxel was designed to evaluate the interest of chemotherapy in non-metastatic prostate cancer patients at high risk of systemic recurrence after initial treatment (radical prostatectomy or radiotherapy).

Drug Docetaxel + hormonal treatment (LH-RH agonist)

Docetaxel will be administered: To D1 of every cycle in the dose of 70 mg/m², Perfusion IV of 60 minutes diluted in 250 ml with physiological serum or with serum glucoside from a peripheral or central vein, Every 3 weeks during 6 cycles (except when unacceptable tolerance). Triptorelin was given by injection for 4 times every 3 months Bicalutamide was given at the same time with LH-RH agonist for 3 weeks ; taken orally

Drug Hormonal treatment (LH-RH agonist)

Triptorelin was given by injection for 4 times every 3 months. Bicalutamide given at the same time with LH-RH agonist for 3 weeks ; taken orally.
