Is this trial a fit for you?

Likely a good fit

Men aged 18 or older with histologically confirmed localized prostate cancer (stages I–III) planned for curative HDR brachytherapy, with no prior pelvic radiation or prostate MRI, and no metastases.

Probably not a fit

Patients without MRI-visible benefits or with risk profiles not influenced by MRI planning may see no difference in outcomes.

What this trial studies

This interventional study randomizes men with localized prostate cancer to HDR brachytherapy planning using CT alone or CT with an MRI. The primary aim is to see if adding MRI affects acute urinary toxicity as measured by EPIC-26 urinary incontinence scores. Secondary goals include longer-term urinary irritative/obstructive symptoms, bowel and sexual domains, and physician-reported toxicity (CTCAE) for both acute and chronic periods. The trial follows participants for 12 months after treatment to compare outcomes and explore treatment efficacy between the two planning approaches.

Why it matters

Potential benefit: If MRI planning improves toxicity profiles, patients may experience fewer urinary or bowel side effects after HDR brachytherapy.

How similar studies have gone: Previous work in imaging-guided planning suggests potential for improved toxicity outcomes with MRI, but direct randomized data for HDR prostate brachytherapy planning remain limited.
