Study Summary

This trial tests whether rectal spacer hydrogel can reduce radiation dose to the rectum in patients with prostate cancer.

Who is the study for?
This trial is for men aged 18-100 with intermediate-risk prostate cancer that hasn't spread beyond the prostate. They must be medically suitable for rectal spacer placement and radiation therapy, have a KPS score of ≥70%, and not have had certain previous surgeries or treatments for prostate cancer.Check my eligibility
What is being tested?
The trial evaluates if injecting a hydrogel called rectal spacer before radiation can protect the rectum from radiation damage in prostate cancer treatment. The gel creates space between the rectum and prostate during stereotactic body radiation therapy and brachytherapy.See study design
What are the potential side effects?
Potential side effects may include discomfort at injection site, possible reaction to materials in the gel, temporary urinary changes, or bowel movement alterations due to the presence of the hydrogel.

Experimental Treatment
Group I: Patients with prostate cancerExperimental Treatment5 Interventions
Patients undergo hydrogel rectal spacer placement on day 1. Within 2 weeks (+/-1 week) after Rectal Spacer placement, patients will be scheduled for CT simulation for external beam treatment planning. Patients will begin the SBRT of 24Gy in 5 fractions within 2 weeks (+/-1 week) from the simulation date. Within 4 weeks (+/-1 week) of last day of SBRT, patients undergo brachytherapy. Patient will return for post-implant CT-based dosimetry analysis 4 weeks (+/- 1 week) post brachytherapy,
