Clinical Outcomes of Patients Undergoing Skin-Reducing Mastectomies

It is a single-center study, conducted exclusively at the European Oncology Institute ( IEO). It is a retrospective study, analyzing events that occurred in the past. The results of this study, aggregating data from numerous patients, could influence public health policies by improving the efficiency and effectiveness of surgical treatments for patients with breast cancer and/or carriers of Breast Cancers mutations. The study is independent and non-profit, conducted by a group with no financial interests, and will collect, in addition to genetic data, clinical and pathological information (related to the disease), information on the types of treatments performed, the presence or absence of recurrences or other tumors, and the survival status of patients. IEO patient data will be transferred in anonymized form (the Oxford group cannot identify patients; only IEO can identify them) using a secure transmission channel. The study has been evaluated and authorized by an independent "Data Governance Board for Retrospective Studies at IEO" considering the scientific relevance of the study and its partners, relevance to the Institute's research lines, and the risk-benefit ratio from scientific, ethical-moral, and personal data protection perspectives.
