Study Summary
We hypothesize that the combination of mammography and CE-MRI will improve the surgeon and radiologist's ability to define extent of disease prior to surgical resection, improve the odds of obtaining clear surgical margins, and increase the efficacy of IORT delivered immediately after initial surgical resection. In this investigation, we will determine whether or not patients deemed eligible for 'immediate" IORT based on mammography and CE-MRI can be successfully treated without the need for re-excision or additional radiotherapy due to inadequate surgical margins.
Primary Outcome
These are the rates of reoperation for re-excision or mastectomy following Wide Local Excision (WLE) or Intraoperative Radiation Therapy (IORT). The number of patients who required reoperation were reported below.
Interventions
- RADIATION Intraoperative radiotherapy
