简要总结
Intraoperative Breast Radiation Therapy (IORT-Breast) utilizing the Xoft Axxent Electronic Brachytherapy System (Xoft) has been recently introduced as a treatment option for women 50 years of age and older who have early stage, low risk Invasive Breast Cancer (IBC). Clinical trials have shown IORT to be non-inferior to whole breast radiation, however some concern continues with rates of recurrence and clinical outcomes.
Given the recent introduction and continued debate it is an excellent opportunity to observe and monitor outcomes in the patients that are treated at Navicent Health through this prospective, observational registry. The opportunity also permits examination of the participant's thoughts and feeling on Quality of Life and Cosmetic Appearance
详细描述
Objectives: (primary and important secondary objectives) The primary objective is to determine rates of recurrence at 5, and 10 years following IORT-Breast at Navicent Health.
Secondary objectives include determination of acute and late effects of IORT-Breast at the treatment site, cosmetic outcomes and satisfaction over 10 years.
In addition, the study will determine why patients who were scheduled for IORT-Breast did not receive it after lumpectomy.
Study Design:
Prospective, observational registry.
