PROSINT Trial Summary

This trial is evaluating treatment outcomes for prostate cancer patients classified as intermediate risk, comparing two different regimens of external beam radiotherapy.

Who is the study for?
Men over 50 with intermediate-risk prostate cancer, which means a Gleason score of 7, PSA levels between >10 and ≤20 ng/mL, and no evidence of spread beyond the prostate. They must have good performance status (able to carry out daily activities), a prostate size ≤100 grams, and an International Prostate Symptom Score ≤15.Check my eligibility
What is being tested?
The study is testing two high-dose radiation treatments using IGRT technology for men with intermediate-risk prostate cancer. One group will receive a single dose of 24 Gy; another will get five doses at 9 Gy each. The trial aims to compare outcomes and side effects like urinary, rectal, and sexual function.See study design
What are the potential side effects?
Potential side effects include issues related to urinary functions such as difficulty urinating or increased frequency, rectal discomfort or bleeding, changes in sexual function including erectile dysfunction. Acute toxicity may involve skin reactions in the treated area.
