N2  - Introduction: There is a growing interest in radiating the internal mammary (IM) nodes in the context of adjuvant radiotherapy in breast cancer. There have been variations in defining its CTV and determining acceptable coverage. Clear definitions are necessary; as such, this paper sought to estimate the dose delivered to an institutionally defined IM CTV using the standard modified wide tangential (MWT) fields. Materials and Methods: IM vessels in the first three intercostal spaces of 10 randomly selected patients were contoured. Then, 5 mm was added and trimmed from anatomical boundaries to create the CTV. Three planning target volumes (PTVs) were created (PTV1, PTV2, and PTV3). Plans were created using a 3D technique with the aim of covering the target volumes by 90%–95% of the dose while keeping the V20 of the ipsilateral lung
