The purpose of this eContouring session is to expand knowledge of breast and regional lymph node anatomy for radiation contouring and treatment planning, focusing on 3 clinical scenarios: partial breast radiation, whole breast radiation and post-mastectomy radiation with comprehensive nodal coverage. The former paradigm in breast cancer, in which the radiation target was defined by the radiation beam placement, is being replaced with a more modern approach in which targets and organs at risk are contoured and the radiation beams are designed to cover the targets with appropriate normal tissue blocking. While strict coverage guidelines are less commonly used in breast cancer, contouring can allow the clinician to identify the most critical target areas and make thoughtful decisions about block placements. Target delineation can also help in assessing dose homogeneity within the target. Accordingly, it is essential for the radiation oncology community to utilize a common nomenclature and common anatomic guidelines for breast cancer contouring. This session will educate participants on this nomenclature and contouring techniques.
