[Partial breast irradiation]

Owing to breast cancer screening, breast cancer is more and more diagnosed at early stage. For those breast cancer women, breast conserving treatment (breast conserving surgery followed by whole breast irradiation) is commonly used since many years. New radiation modalities have been recently developed in early breast cancers particularly accelerated partial breast irradiation (APBI). Among all techniques of radiotherapy, 3D-conformal APBI and intraoperative radiotherapy (IORT) are the main modalities of radiotherapy used. The present review states on indications, treatment modalities and updated results of local control and side effects of partial breast irradiation.
