In that way the investigators tried to definde clarly the correct indications for this type of reconstruction.\n\nIn addition, the investigators would like to define if the postoperative radiation therapy agument the complications rate and the capsular contracture incidence.\n\nThe investigators decide to perform prepectoral breast reconstruction also in 20 patientes underwent previous radiotherapy dependig on the grade of cutaneus radiodistrophy, so to propose our less invasive approach to these patients normally candidates to autologus breast reconstruction'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'genderBased': True, 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patientes undergone immediate prepectoral breast reconstruction with polyurethane implantes', 'genderDescription': 'we included only famale patients underwent mastectomy and immediate breast reconstruction in the prepectoral plane with polyurethane implantes', 'eligibilityCriteria': 'Inclusion Criteria:\n\n* patients underwent prepectoral breast recosntruction with polyurethane implants after skin or nipple sparing masectomy\n* adequate mastectomy flap in vascularity and thickness\n\nExclusion Criteria:\n\n* none'}, 'identificationModule': {'nctId': 'NCT06216106', 'acronym': 'IBR-PPBR', 'briefTitle': 'Data Collection of Prepectoral Breast Reconstruction With Polyurethane Implantes', 'organization': {'class': 'OTHER', 'fullName': 'European Institute of Oncology'}, 'officialTitle': 'Prepectoral Breast Reconstruction With Polyurethane Implantes and Radiotherapy: a Single Center Retrospective Study Evaluating Risk and Complications', 'orgStudyIdInfo': {'id': 'UID 4260'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'patients undergone prepectoral breast reconstruction', 'description': 'As the retrospective nature of this study, we have no exlusion criterias.
