Phase 2 : monocentric prospective comparative cohort study.
Recruitment :
* "Centre intégré de cancérologie du CHU de Québec-Université Laval."

* TRUS prostate localisation.
* Prostate volume measurement.
* Gold fiducial markers (3) insertion.
* Prostate brachytherapy catheters (14 à 21) insertion.
* Cystoscopy for bladder and urethra integrity control.
* Re-insertion of foley catheter after cystoscopy.
Planning imaging: TRUS or CT scan (has needed).
Structures delineation by radiation oncologist (brachytherapist).
* Prostate
* Seminale vesicles
* Rectum
* Colon sigmoïde
* Bladder
* Urethra
* Penile bulb
Dosimetric optimisation

Treatment (brachytherapy dose delivery).
* 15 Gy in one fraction
* Direct interstitial dose monitoring (20 patients or more). Fiber-optic dosimeter inserted in prostate brachytherpy catheter for live dose delivery mesurements.
Foley ablation under full bladder, same day or day after therapy.

* Dose : 25 Gy in 5 fractions administered over a 7 days period. 2 to 3 fractions separated by 2 days, weekend break.
* PTV includes prostate and the first centimeter of seminal vesicle.
Simulation
* one week post brachytherapy
* standard has described in the department procedure manual.
* maximal CT scan slice thickness : 2-3mm.
* uretro-graphy done to identify urogenital sphincter.
Multiparametric MRI
* If no counter-indication and available,
* a T2 tridimensional sequence for prostate delineation
* slice thickness : 1 mm.
* a diffusion weighted sequence will be done.
* a DTI with tractography can be done optionally.
* contrast media (gadolinium) is optional.
Physique
* Linac energy (between 6 MV to 18 MV).
* ARC therapy technique will be used
* planification softwares: Éclipse, Pinnacle or Raystation.
* Portal (kV-kV) imagery will be used for marker match.
* CBCT will be done at each fraction delivered.
Clinical and dosimetric data will be collected prior treatment.
Primary objectives :
* Toxicity analysis will be quantitatively evaluated using CTCAE (v5) at 1, 2 and 5 years post-therapy, and has needed at FU visits. Kaplan-Meier statistical analysis will be used to report toxicity evolution through time.
* median IPSS scores will be reported at 3, 6, 12 months and yearly (1, 2, 3, 4 et 5) post-therapy. IPSS median time to baseline return will be calculated.
* IPSS urinary scores, sexual function (SHIM) and GI toxicity (CTCAE-v5) and quality of life questionnaires ( EPIC-26) will be given at 3, 6 months and yearly thereafter (1, 2, 3, 4 et 5) post-treatment.
Secondary objectives : Biochemical disease-free survival has per Phoenix definition (by American Society of Radiation Oncology - ASTRO) recommendation will be reported using Kaplan-Meier analysis.
