Summary

This trial will study whether radiation therapy is more effective with or without trastuzumab in treating ductal carcinoma in situ.

See full description
Who is the study for?
This trial is for women who've had a lumpectomy to remove ductal carcinoma in situ (DCIS) that's HER2-positive. They should have no DCIS at the surgery margins, be cancer-free elsewhere, and not pregnant or breastfeeding. Participants must be relatively healthy with an ECOG status of 0 or 1 and able to follow up long-term.Check my eligibility
What is being tested?
The study compares radiation therapy alone versus radiation combined with Trastuzumab, a monoclonal antibody that targets tumor cells. It aims to discover if adding Trastuzumab improves treatment outcomes for HER2-positive DCIS after lumpectomy.See study design
What are the potential side effects?
Trastuzumab can cause heart problems, allergic reactions, flu-like symptoms, nausea, diarrhea, and fatigue. Radiation may lead to skin changes like redness and irritation in the treated area as well as fatigue.
