%X The aim of the study was to analyze the interinstitutional differences in the planning process/approach of regional nodal irradiation (RNI) in breast cancer patients in expert centres. Based on a predefined risk constellation, the left breast and the axillary, periclavicular and internal mammarian lymph node areas had to be irradiated. The study focused on left-sided RNI. One CT dataset (free breathing) each of a regular (R) adipose (A) and a slender patient (S) were centrally selected and all target volumes (CTV: level II, III, IV + internal mammary artery chain region-IMC, left breast, PTV and OARs) were contoured according to the ESTRO recommendations. A total dose of 50.4/1.8 Gy was set as the dosage with free choice of technique/inclinic constraints. Dose files were analyzed centrally as DICOM files (CTV: D95
