Imaging for early stage breast cancer

APBI techniques

Techniques

➢ Non-invasive

➢ 3D External radiotherapy

➢ Photons/ electrons: 10 #, 2/d, 5 d ➢ IMRT (Intensity Modulated Radiation Therapy) ➢ photons: same fractionation but better conformation

✓ Avantages: ▪

knowledge of final AP results

▪ techniques available in all radiotherapy centers

✓ Disadvantages: ▪

healthy organs irradiated at low doses ▪ difficulties in targeting the tumor bed ▪ risk of hot spots
