Registry for Intra-Operative Radiotherapy During Breast Conserving Surgery in Patients With Early Stage Breast Cancer

This is a prospective, registry study that will enroll all women with early stage breast cancer who will be treated with intraoperative radiotherapy (IORT) during breast-conserving surgery. The purpose of this study is to further validate the long-term effectiveness and safety of this treatment method. We aim to assess short and long-term patient outcomes associated with IORT, including perioperative complications, local and distance disease recurrences, as well as disease-free survival and overall survival.
