NCT02271659

Brief Summary

The aim of the present phase III study is two-folded: 1) to show a superiority of external beam radiotherapy combined with a brachytherapy boost versus exclusive external beam radiotherapy and 2) to evaluate the economic impact of each treatment. The study includes 33 cancer centres, the inclusion time is of 2 years and the follow-up is of 5 years.

Outcome Measures

Primary Outcomes (1)

  • Comparison of the biochemical relapse free survival of the patients in two groups at 5 years for an external beam radiotherapy with a brachytherapy boost versus an exclusive external beam radiotherapy

    Biochemical relapse is defined using the Phoenix definition of nadir of Prostate Specific Antigen + 2 ng/ml. This will be studied for both arms

    5 years

Secondary Outcomes (5)

  • The evaluation of the overall survival at 5 years.

    5 years

  • The evaluation of the specific survival at 5 years

    5 years

  • The evaluation of the survival without any metastatic evolution at 5 years

    5 years

  • The study of all toxicities

    5 years

  • Medical and economical evaluation.

    5 years

Study Arms (2)

Brachytherapy boost

EXPERIMENTAL

Brachytherapy boost with external beam radiotherapy. External beam radiotherapy of 46 Gy delivered to the prostate and the first centimeter of the seminal vesicles with a brachytherapy boost (of iodine-125 seeds (110Gy) or high dose rate (14Gy) with iridium-192) only to the prostate. Each center will choose the appropriate brachytherapy technique

Radiation: Brachytherapy boost with external beam radiotherapy

Exclusive external beam irradiation

ACTIVE COMPARATOR

Exclusive external beam radiotherapy. External beam radiotherapy of 46 Gy delivered to the prostate and the first centimeter of the seminal vesicles with an external beam radiotherapy of 80 Gy to the prostate alone.

Radiation: Exclusive external beam radiotherapy

Interventions

Bras A: External beam radiotherapy of 46 Gy delivered with a linear accelerator (Varian) to the prostate and the first centimeter of the seminal vesicles with a brachytherapy boost (of iodine-125 seeds from Bard (110Gy) or high dose rate (14Gy) with a iridium-192 source) only to the prostate. Each center will choose the appropriate brachytherapy technique. The number of seeds or needles will depend on the prostate's volume.

Brachytherapy boost

Bras B: External beam radiotherapy of 46 Gy delivered with photons and a linear accelerator (Varian) to the prostate and the first centimeter of the seminal vesicles with an external beam radiotherapy of 80 Gy to the prostate alone.

Exclusive external beam irradiation

Eligibility Criteria

Age18 Years - 80 Years
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • age between 18 and 80 years;
  • life expectancy of greater than 10 years;
  • prostate adenocarcinoma histologically proven;
  • prostate cancer has to be of intermediate-risk based on at least one of the three following criteria: PSA between 10 ng/ml and 20 ng/ml, and/or a Gleason score of 7 and/or a T2B. Karnofsky performance status ≥ 60% and consequently performance status ECOG 0-2.
  • the patient has to be the beneficiary of the social security system (order n° 2006-477 from April 26th 2006);
  • the signed consent form.

You may not qualify if:

  • PSA level \> 20;
  • Gleason \> 7;
  • prostate volume \> 60 cc;
  • pelvic lymph nodes involvement at dissection or imaging (ADP \> 1.5 cm);
  • concurrent hormone therapy;
  • the presence of distant metastasis (M1);
  • history of abdominal or pelvic irradiation;
  • history of prostate resection in the previous 6 months and/or not allowing the implantation of markers;
  • history of uncontrolled cancer and/or treated since less than 5 years (excepting the basal-cell carcinoma);
  • urinary discomfort with an IPSS (International Prostate Symptom Score) \> 15 (without alpha-blocking);
  • inflammatory bowel disorder such as ulcerative colitis or the Crohn's disease;
  • other undergoing study that may interfere with the present study;
  • patient under legal protection measure.
