The key recommendations of the Society of Surgical Oncology–American Society for Radiation Oncology–American Society of Clinical Oncology Consensus Guideline on Margins for Breast-Conserving Surgery With Whole-Breast Irradiation in Ductal Carcinoma in Situ include:

  • Positive margins had a twofold higher risk for IBTR

  • Wider margins do not significantly decrease IBTR compared with 2-mm margins

  • Biologic subtypes do not indicate the need for margins wider than no ink on tumor

  • IBTR rates are lowered with the use of systemic therapy
