Summary

This trial compares two treatments for a type of breast cancer called DCIS. One group will have surgery, while the other will have radiation followed by surgery. The goal is to see if radiation before surgery improves treatment outcomes.

Who is the study for?
This trial is for individuals with non-palpable, image-detected ductal carcinoma in situ (DCIS) of the breast measuring up to 4 cm. Participants must have a biopsy marker placed and an ECOG performance status of 0-2. Prior contralateral breast cancer is okay, but not ipsilateral cancer or multicentric/multifocal DCIS, Paget's disease, invasive carcinoma on biopsy, mass lesions/palpable tumors over 4 cm, or positive lymph nodes.
What is being tested?
The study compares immediate surgical removal (lumpectomy) versus radiation therapy followed by delayed surgery for treating DCIS. The goal is to assess which method is more effective based on pathological findings from the excised tissue.
What are the potential side effects?
Potential side effects include skin changes like redness and irritation from radiation therapy; pain, swelling, infection risk at the surgery site; fatigue from both treatments; and possible scarring or changes in breast shape.

Other Research
Neoadjuvant radiotherapy for Ductal Carcinoma involves the use of high-energy radiation to kill cancer cells or shrink tumors before surgery. This approach aims to reduce the tumor size, making surgical removal easier and potentially sparing more healthy tissue. By targeting the tumor preoperatively, it may also reduce the risk of local recurrence, improving surgical outcomes and potentially enhancing long-term survival rates for patients.
