Comparison of Target Volume Coverage and Organs at Risk in Contoured Regional Nodes versus a Field-based Approach in Adjuvant Breast Radiotherapy

Purpose: Regional nodal irradiation (RNI) reduces recurrence in high-risk breast cancer. Despite international contouring guidelines, including the European Society for Radiotherapy and Oncology (ESTRO) consensus to improve target volume delineation [1], many institutions still use conventional field radiotherapy based on anatomical landmarks. We aimed to assess target volume coverage and dose to organs-at-risk (OARs) between volumes created by nodal contouring and anatomical landmarks.
