Comparing two types of radiation therapy for prostate cancer treatment

ULTRA-HYPO Fractionated (UHF) Compared to Moderate-HYPO Fractionated (MHF) Prostate IGRT With HDR Brachytherapy BOOST : A Phase 1-2 Study.

Not applicable Interventional CHU de Quebec-Universite Laval · NCT05786742

This study is testing whether a new type of radiation therapy for prostate cancer works better and is safer than a different method, while also looking at how well the treatment is tolerated by patients.

What this trial studies

This clinical trial evaluates the effectiveness and safety of ultra-hypofractionated radiation therapy compared to moderately hypofractionated radiation therapy, combined with high-dose-rate brachytherapy for prostate cancer. It involves a feasibility phase with 28 patients followed by a comparative cohort study. The study aims to assess toxicity, acceptability, and long-term survival outcomes while monitoring the precision of radiation delivery using advanced imaging techniques. The trial is conducted at the Centre intégré de cancérologie du CHU de Québec-Université Laval.

Who should consider this trial

Good fit: Ideal candidates include men with biopsy-proven prostate adenocarcinoma at specific stages (T1c, T2) and with a Gleason score of 6 or 7.

Not a fit: Patients with advanced prostate cancer (T3 or T4), high Gleason scores (8-10), or those who have had prior pelvic radiotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and less toxic radiation treatment options for prostate cancer patients.

How similar studies have performed: Other studies have shown promising results with hypofractionated radiation therapy approaches, suggesting potential for success in this trial.
