Summary

This trial is testing a new cancer treatment that combines two different types of radiation therapy. The first part of the treatment involves placing radioactive material inside the patient's body for a short time. The second part of the treatment uses a new type of radiation therapy that delivers very high doses of radiation to tumors with high precision. The purpose of the trial is to determine if this new treatment is safe.

Who is the study for?
Men over 18 with intermediate-risk prostate cancer (specific criteria like T2b-T2c, Gleason score of 7, or PSA levels of 10-20 ng/ml) without metastatic disease can join. They must have certain blood cell counts, agree to use contraception for three months post-treatment, and not have had previous pelvic radiation or surgeries that could complicate treatment.
What is being tested?
The trial is testing the safety of combining two types of radiation therapy: high-dose rate brachytherapy (internal radiation) and stereotactic body radiation therapy (SBRT), which delivers precise doses in a short period. The goal is to see if this combination effectively treats prostate cancer.
What are the potential side effects?
Possible side effects include irritation at the site where radioactive material is placed for brachytherapy, fatigue from SBRT treatments, skin reactions similar to sunburns, urinary issues such as frequency or discomfort, bowel changes like diarrhea or rectal bleeding.
