High impact on RT nodal fields

• Increasing use of neo-adjuvant chemotherapy

• Indication for nodal irradiation based on risk assessment

• Before NAC and after NAC

• Identify indication for RT as early as possible

• Standard imaging is not adequate

• SN No number / location of involved nodes

• US/fna No number / location, not all areas

• MR No overview of all areas at risk

FDG-PET/CT 18%

• 12% unexpected ≥4 axillary nodes

• 11% unexpected N3
