PBSI Trial Summary

This trial is investigating a new form of breast cancer radiation treatment that is less toxic and more affordable than current methods.

Who is the study for?
This trial is for postmenopausal women over 55 with early-stage breast cancer (Stage 0 or I, tumor <2cm) that's been surgically removed with clear margins. Participants must have a life expectancy of at least ten years and cannot have had certain other cancers unless disease-free for five years. Those with genetic mutations in BRCA, high-grade tumors, unclear surgical sites, or previous chest radiotherapy are excluded.Check my eligibility
What is being tested?
The study tests a type of partial breast radiation therapy using Palladium-103 seed implants after lumpectomy in patients with specific types of breast cancer. It aims to refine the technique and gather data on its side effects and costs compared to other treatments.See study design
What are the potential side effects?
While not explicitly listed here, typical side effects from similar radiation therapies may include skin changes like redness or irritation at the treatment site, fatigue, discomfort or pain around the implant area, and potential short-term swelling.
