ClinConnect Summary

This clinical trial is studying a new way to treat prostate cancer using a special type of radiation called proton therapy, combined with a boost from a procedure called brachytherapy. This treatment is aimed at men who have high-risk or unfavorable intermediate-risk prostate cancer, particularly those at a higher risk of cancer spreading to nearby lymph nodes. The trial is currently looking for participants aged 65 to 74, but it is open to all eligible men over the age of 18.

To be eligible for this study, participants must have been diagnosed with prostate cancer and fall into specific risk categories based on factors like the stage of cancer and PSA levels (a blood test marker for prostate cancer). Those interested will undergo several tests to ensure they are suitable for the treatment and must be in good overall health to participate. If you join the trial, you can expect to receive this innovative treatment, along with regular check-ups and assessments to monitor your progress. It's important to discuss this opportunity with your doctor to see if it might be a good fit for you or your loved one.
