Partial breast radiation with SAVI addresses two key issues in breast cancer radiation treatment: exposure to healthy tissue and length of treatment. SAVI’s multiple catheters and open-architecture design allow for the precise delivery of radiation. This enables physicians to optimally spare normal tissues, which can improve outcomes and increase the number of women who may be eligible for breast conservation therapy (BCT).
For women who face hurdles completing an extended treatment schedule, SAVI reduces radiation treatment time from several weeks to just 5 days. Many women consider this accelerated schedule to be a significant benefit.
The SAVI applicator is inserted into the tumor cavity through a small incision in the breast. The catheters are expanded to fit the size and shape of the cavity, and a tiny radioactive seed is placed in each catheter. This allows every catheter to deliver an individual dose of radiation, so physicians can customize breast cancer treatment, regardless of the size, shape or location of the lumpectomy cavity. Treatment takes place twice a day over 5 days.
