Accelerated Partial Breast Irradiation(APBI) is a newer treatment alternative for some women who have undergone breast conserving surgery. It delivers radiation from inside the body directly to the lumpectomy site (the space left after the tumor is removed) and directly to the tissue surrounding the cavity where the cancer is most likely to recur.

After the surgeon performs the lumpectomy, an uninflated balloon connected to a catheter, is placed inside the cavity while a portion of the catheter remains outside of the breast. APBI is given under the direction of a radiation oncologist who will determine the amount of radiation needed. It is delivered on an outpatient basis twice a day for 5 days.

During treatment, the portion of the catheter that remains outside the breast will be connected to a computer-controlled machine. Radiation is delivered to the breast via the catheter. Once completed, the machine is disconnected and no radiation will remain in the breast between treatments or after final treatment.

More about the Axxent® Electronic Brachytherapy System

The Axxent® Electronic Brachytherapy System utilizes a proprietary miniaturized X-ray source to apply radiation directly to a tumor bed within the body. Unlike conventional HDR brachytherapy technologies, the Axxent System does not require radioactive isotopes or heavy shielding. Therefore, the medical clinician can remain in room during treatment, providing continuous patient monitoring and care. The system is designed to deliver a therapeutic dose directly to the tumor bed while applying less radiation to tissue beyond the target area, potentially reducing treatment time from seven weeks to five days.

The Axxent Balloon Applicator is a key component of the Axxent® Electronic Brachytherapy System, a unique treatment solution for Accelerated Partial Breast Irradiation (APBI). Axxent Balloon Applicators are available in multiple sizes and shapes to best fit the contour of the lumpectomy cavity, which allows the radiation dose to conform to the size and shape of the cavity. Inserted through a single incision, the balloon catheter provides a channel for the Axxent HDR X-ray source to deliver high-dose rate, low energy radiation treatment.
