NCT ID NCT01841749
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at 228 women with ductal carcinoma in situ (DCIS) or micro-invasive DCIS who needed a mastectomy. Researchers wanted to see if doing a sentinel lymph node biopsy upfront could help avoid a more extensive axillary lymph node dissection later. The goal was to find out how many women could be spared unnecessary extra surgery.
