Breast radiotherapy has undergone significant innovation in the past 10 years and the frequency of image-guided radiation therapy (IGRT) is increasing. This session will review clinical indications for breast radiotherapy (RT) and conventional RT methods. Ongoing clinical innovations in breast RT techniques will then be highlighted (e.g., partial breast irradiation, IMRT and VMAT for irradiation of the internal mammary chain). Finally, the emerging role of IGRT will be discussed with its application to improving setup reproducibility and designing appropriate target margins. The IGRT methods will include surface imaging although the focus will remain on more widely-available IGRT systems such as CBCT and kV imaging.
a. Brief clinical review of RT as a function of breast cancer stage according to RTOG guidelines
b. Dosimetric advances in breast RT, including IMRT and VMAT for nodal irradiation and partial breast irradiation for early-stage cancer
c. The role of IGRT for setup reproducibility and margin design
d. IGRT for adaptive RT in cases of seroma reduction

Learning Objectives:
1. Review the clinical targets for breast RT as a function of cancer stage
2. Learn about innovative uses of advanced radiotherapy techniques for breast treatment
3. Highlight the emerging role of IGRT to guide planning and treatment
