Title: Phase III Multicentric Trial Comparing Accelerated Partial Breast Irradiation (APBI) Versus Standard or Hypofractionated Whole Breast Irradiation in Low Risk of Local Recurrence of Breast Cancer
Brief Summary: The standard treatment for localized breast cancer is based on conservative surgery (when possible) followed by radiation therapy (RT) delivered to the whole breast. The recommended total RT dose is 45 to 50 Gy delivered in 4.5 to 5 weeks followed by a 10 to 16 Gy boost to the tumor bed for 1 to 1.5 weeks. The rationale for the development of APBI was based on the difficulty for many patients to reach RT centers to receive standard whole breast irradiation (WBI) after conservative surgery. APBI offers decreased overall treatment time and several theoretical advantages over WBI, including a decrease in dose delivered to uninvolved portions of the breast and adjacent organs. If equivalence between the two treatments can be shown, then APBI will be considered as a historic evolution in breast cancer management.

In this phase III trial, designed in postmenopausal women \>50 years of age, the objective is to compare the effectiveness and safety of APBI compared with whole breast irradiation. This study is also designed to ensure high quality criteria for surgery, pathology and RT techniques in the 3 arms and will allow to provide data on economics and costs.
