Course Overview
Whole breast irradiation (WBI) has been used for decades to ensure all cancers cells have been destroyed post-breast surgery, but WBI has several disadvantages, including the detrimental effects of radiation exposure to the surrounding organs and skin. Accelerated partial breast irradiation (APBI) precisely targets the desired volume of tissues, thereby reducing radiation exposure to non-target areas and with potentially improved cosmesis. [1]

Dr. Mark will discuss the history of breast conservation radiation therapy, the benefits and disadvantages of whole breast vs accelerated partial breast irradiation, as well as review available markers and devices for precision radiation guidance.

Educational Objectives
At the conclusion of this activity, participants should be better able to:

  • Compare and contrast whole breast irradiation (WBI) to accelerated partial breast irradiation (APBI), including radiation safety and patient satisfaction
  • Describe APBI options, including external beam radiation therapy, brachytherapy,  and intraoperative radiation therapy
  • Explain the advantages and disadvantages of devices currently used to ensure precision radiation therapy
