Accelerated Partial Breast Irradiation (APBI)


Accelerated Partial Breast Irradiation (APBI) is a localized form of radiation treatment (brachytherapy) that involves the implantation of a radioactive seed to destroy cancer cells that may remain after surgery. This highly effective dose of radiation greatly reduces treatment times for patients compared to other therapies, with treatment taking place twice a day for five days.

At DuPage Medical Group, radiation oncologists use the Strut Assisted Volume Implant (SAVI®) applicator for breast brachytherapy, which delivers radiation from inside the breast. The SAVI applicator is inserted into the tumor cavity through a small incision in the breast about one to four weeks after a lumpectomy. Each catheter can expand to fit the size and shape of the breast cavity and has a tiny radioactive seed placed into each catheter.
