Testing surgery alone for low-risk ductal carcinoma in situ
Part of Cancer clinical trials.
This trial studies whether removing the abnormal breast cells with breast-conserving surgery only (without additional treatment) is enough for people with low-risk ductal carcinoma in situ (DCIS). It may help some patients avoid extra treatments if their risk is very low.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a woman older than 45
- Your DCIS is not “microinvasive” and has no spread into nearby tissue
- The tumor is 2.5 cm or smaller
- You had breast-conserving surgery and the margins are clear (no remaining DCIS at the edges, or only small margin limits as allowed)
- Your Oncotype DX DCIS score predicts a 10-year local recurrence risk of 10% or less
- Your DCIS is not multifocal (not found in multiple separate areas)

This study collects information from people with breast ductal carcinoma in situ (DCIS) to see how a specific lab test (DCISionRT) may help predict who benefits from radiation and/or certain medications. Your results and clinical details are gathered during routine care, not necessarily to change treatment right away.
This trial tests whether doing a sentinel lymph node biopsy later (after breast surgery) is a safe, accurate way to check if cancer has spread. It uses a special tracking shot that helps find the lymph nodes.
This trial tests whether doing a “sentinel lymph node biopsy” later (a delayed biopsy) can help assess whether cancer has spread to lymph nodes in people having a mastectomy for DCIS. It may help avoid unnecessary aggressive treatment if lymph nodes look normal.
This study is looking at whether it is safe for younger women who have had surgery for a very early-stage, low-risk breast condition called DCIS to skip radiation therapy. The goal is to see if they can avoid the side effects of radiation without the cancer coming back.
This trial compares skipping radiation therapy after breast-conserving surgery for low- or intermediate-risk ductal carcinoma in situ (DCIS) – a very early, non-invasive breast cancer. It aims to see if omitting radiation is as effective as standard treatment while reducing side effects.
This trial studies giving radiation during surgery for women with a certain early breast condition called ductal carcinoma in situ (DCIS). It may help lower the chance that the DCIS comes back, especially when combined with breast-conserving surgery.
