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.\n\nIn 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.', 'detailedDescription': 'Following breast conservative surgery, patients will be stratified according to the following prognostic factors using a minimisation technique: age (\\<70 vs ≥70), HER2 status (HER2+ vs HER2-), hormonal receptor status (RH+ vs RH-) and lymph node invasion (pN0 vs pN0i+).\n\nPatients will be allocated to receive either standard treatment, hypofractionated treatment or APBI.\n\nRadiation therapy should be started between 4 and 12 weeks after the last surgery.\n\nPatients treated with standard whole breast irradiation will receive a total dose of 50 Gy in 25 fractions, 2 Gy per day, 5 days a week. The boost of 16 Gy will be delivered in 8 fractions for all patients after completion of the 50 Gy, without interruption. All patients will receive one fraction per day, 5 fractions a week.\n\nPatients treated with hypofractionated irradiation will receive a total dose of either 40 Gy (in 15 fractions, 2.66 Gy per day) or 42.5 Gy (in 16 fractions, 2.65 Gy per day) 5 days a week.\n\nPatients treated with APBI will receive a total dose of 40 Gy in 10 fractions, delivered twice a day over a time period of 5-7 days. Each daily dose must be separated by 6 hours.\n\nPatients will be followed at 3 and 6 month after the last dose of irradiation, at 12 months after the date of last surgery and then on a yearly basis during 10 years.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '50 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Women aged ≥50 years\n* Menopausal status confirmed\n* Pathology confirmation of invasive carcinoma (all types)\n* Complete tumor removal and conservative surgery\n* Pathologic tumor size of invasive carcinoma ≤2 cm (including the in situ component) pT1\n* All histopathologic grades\n* Clear lateral margins for the invasive and in situ disease (\\>2 mm)\n* pN0 or pN(i+)\n* No metastasis\n* Radiotherapy should be started more than 4 weeks and less than 12 weeks after last surgery\n* Surgical clips (4 to 5 clips in the tumor bed)\n* No prior breast or mediastinal radiotherapy\n* Eastern Cooperative Oncology Group (ECOG) 0-1\n* Information to the patient and signed informed consent\n\nExclusion Criteria:\n\n* Multifocal invasive ductal carcinoma defined as the presence of at least two distinct tumors that are separated by normal tissue or when the distance between the two lesions does not permit conservative surgery\n* Bilateral breast cancer\n* No or less than 4 surgical clips in the tumor bed\n* Nodal involvement : pN1 (including micrometastasis, mi+), pN2, pN3\n* Metastatic disease\n* internal mammary node involvement or supraclavicular lymph node involvement\n* Indication of chemotherapy or trastuzumab\n* Involved or close lateral margins for the invasive and /or in situ components (\\<2 mm) AND impossibility to re-operate or impossible to perform another conservative surgery\n* Patients with known BRCA1 or BRCA2 mutations\n* Previous mammoplasty\n* Previous homolateral breast and/or mediastinal irradiation\n* Previous invasive cancer (except basocellular epithelioma or in situ carcinoma of the cervix)\n* No geographical, social or psychologic reasons that would prevent study follow'}, 'identificationModule': {'nctId': 'NCT01247233', 'acronym': 'SHARE', 'briefTitle': 'Standard or Hypofractionated Radiotherapy Versus Accelerated Partial Breast Irradiation (APBI) for Breast Cancer', 'organization': {'class': 'OTHER', 'fullName': 'UNICANCER'}, 'officialTitle': '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', 'orgStudyIdInfo': {'id': 'RTS02-SHARE'}, 'secondaryIdInfos': [{'id': '2010-A00243-36', 'type': 'OTHER', 'domain': 'ID-RCB'}, {'id': 'UC-0140/1001', 'type': 'OTHER', 'domain': 'UNICANCER'}, {'id': 'RTS02 / SHARE', 'type': 'OTHER', 'domain': 'UNICANCER'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Standard or Hypofractionated radiotherapy', 'description': 'Whole breast RT, 50 Gy + "boost" 16 Gy.
