Study Summary

This trial is studying a way to make radiation therapy safer and more efficient, potentially reducing resources and stress on departments.

Who is the study for?
Men aged 18+ with low to intermediate risk prostate cancer, who haven't had treatment for it or androgen deprivation therapy. They must be fit enough for the procedure (ECOG <2), able to consent, and if HIV/HBV/HCV positive, they need controlled viral loads. Those with other cancers can join if it doesn't affect this trial's safety or results.Check my eligibility
What is being tested?
The study is testing a high dose rate (HDR) brachytherapy as the only treatment for prostate cancer given in two sessions just 3 hours apart. This approach could make treatment quicker and easier on healthcare systems compared to current methods where treatments are spaced further apart.See study design
What are the potential side effects?
Potential side effects of HDR brachytherapy may include discomfort at the implant site, urinary issues like frequency or urgency, bowel changes, erectile dysfunction, and fatigue. These vary by individual.
