Arms Assigned Interventions
Experimental: Brachytherapy + Decapeptyl® SR 22.5mg Triptorelin Other: Brachytherapy + Decapeptyl® SR 22.5mg Triptorelin
Brachytherapy: Low dose rate or high dose rate. Triptorelin: Single injection (22.5 mg), intramuscular injection, preferably 2 months before brachytherapy.
Active Comparator: Brachytherapy Radiation: Brachytherapy
Brachytherapy: Low dose rate or high dose rate.


Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • A history of prostate cancer (T1-T2-T3 N0 M0), confirmed through histopathology and initially treated with radiotherapy.
  • Biochemical failure due to Phoenix criteria (nadir + 2) and local recurrence of the initial prostate cancer, confirmed by prostate biopsy, with neither regional involvement nor distant metastases.
  • Late local recurrence of the initial prostate cancer. A recurrence is late when it appears after longer than 18 months post- radiotherapy.
  • PSA < 10 ng/ml at the time of recurrence.

Exclusion Criteria:

  • Evidence of metastatic disease.
  • Previous evidence of hormone-resistant cancer.
  • Patients currently receiving or having received either Luteinizing hormone-releasing hormone (LH-RH) agonists, or antagonists, over the last 12 months.
  • Patients with known hypersensitivity to triptorelin, LH-RH, other LH-RH-analogous agonists, or any of triptorelin 22.5 mg's excipients.
