At the 2009 American Society of Breast Surgeons annual meeting last month, researchers from the Moores Cancer Center at UC San Diego and 21st Century Oncology presented the results of their study – Accelerated Partial Breast Irradiation via SAVI: One Year Follow-up.
With a median follow-up of 18 months, this study represents the longest follow-up on treatment with the SAVI applicator presented to date.
In addition to treating small breasts and small lumpectomy cavities, the results indicate a significant reduction in complications typically associated with balloon brachytherapy. Cosmetic results have been outstanding with no local recurrences or persistent seroma.
Additionally, 39% percent of patients had skin separation of 7 mm or less – making them ineligible for treatment with balloon brachytherapy.
“With greater than a full year of follow-up, our research confirms previous findings that this device is safe and effective for radiation delivery,” said study author Catheryn Yashar, M.D. of UCSD. “Without the ability to customize the dose, other devices may lead to complications, like persistent seroma and skin burns. [SAVI] was created to overcome these problems, and our research shows it has been successful.”
