Frequency of whole breast radiation therapy after intraoperative radiation therapy due to criteria identified by lumpectomy

WBRT recommendation rates of 30-33% after lumpectomy and IORT are observed when the WBRT indication is a single ASTRO cautionary/unsuitable, Groupe Européen de Curiethérapie-European Society for Therapeutic Radiology and Oncology intermediate/high-risk criterion, or TARGeted Intraoperative radioTherapy vs. postoperative radiotherapy trial protocol recommendation. Alternatively, allowing for re-excision to clear margins and accepting one ASTRO cautionary factor lowered the rate of WBRT recommendation to 9.5%.
