RATIONALE: Androgens can stimulate the growth of prostate cancer cells. Hormone therapy using triptorelin may fight prostate cancer by reducing the production of androgens.
PURPOSE: Randomized phase III trial to compare the effectiveness of long-term hormone therapy and triptorelin with no further treatment in treating patients who have advanced prostate cancer previously treated with radiation therapy and 6 months of androgen suppression.
|Condition or disease||Intervention/treatment||Phase|
|Prostate Cancer||Drug: bicalutamide Drug: flutamide Drug: triptorelin Radiation: radiation therapy||Phase 3|
- Determine the best hormonal scheme to be associated with pelvic radiotherapy in the curative management of prostatic carcinoma for hormonal treatment with regards to treatment outcome (overall survival, clinical disease free survival, local regional control), quality of life (treatment side effects, sexual function), and health economy (cost effectiveness ratio).
OUTLINE: This is a randomized, multicenter study.
Patients receive external radiation for 5 weeks, followed by a pelvic boost given for 2 weeks and a 6 month combined androgen blockage initiated at the onset of external irradiation. Flutamide (Eulexin) or bicalutamide (Casodex) may be used as the antiandrogens. Antiandrogen treatment starts 1 week before the first injection of triptorelin.
Patients are then randomized to one of two treatment arms.
- Arm I: Patients receive no further treatment.
- Arm II: Patients receive antiandrogen for 2.5 years plus and LHRH analogue (triptorelin) administered every 3 months. Patients then continue the LHRH analogue alone for an additional 2.5 years in the absence of disease progression.
Patients are followed every 6 months for 5 years and then annually thereafter.
PROJECTED ACCRUAL: A total of 966 patients will be accrued over 5 years.
