AccuBoost®

Non-Invasive breast cancer radiation treatment

Women with early-stage breast cancer have increasing number of treatment options with Breast Conservation Therapy (BCT). BCT starts with the surgical removal of cancerous tissue with a procedure known as lumpectomy. The optimal treatment plan for each patient is an important discussion with the surgeon, radiation oncologist and medical oncologist. Provided below is information on two of the most popular approaches to the radiation portion of BCT.

Radiation Therapy process:
Breast conservation therapy (BCT) can include radiation therapy to the whole breast or to part of the breast affected by breast cancer only. Whole Breast Irradiation (WBI) is delivered with large linear accelerators delivering external beam radiation therapy (EBRT) while the second approach is of partial breast or Accelerated Partial Breast Irradiation (APBI) can be delivered with EBRT or radioactive brachytherapy sources. AccuBoost technology is able to support either of these approaches.

Whole Breast Irradiation
In this approach, the lumpectomy surgery is followed by daily sessions of radiation therapy to the whole breast for four to six weeks. Whole breast irradiation (WBI) is looked at by many as the "gold standard" for breast radiotherapy based on over three decades of experience. The WBI protocol also requires additional localized radiation, known as the "boost" dose, aimed only at the tissue surrounding the tumor bed. AccuBoost therapy can be utilized during the "boost" portion of whole breast radiation therapy. The combination of surgery and completion of radiation therapy has been effective in preventing cancer recurrence. Numerous studies show that women with early stage disease have a clear option to preserve the breast and fight off the cancer.

Accelerated Partial Breast Irradiation
Developed over the last 15 years, this approach treats only the tissue immediately around the lumpectomy cavity, sparing the unaffected breast, lung and chest wall from radiation. This approach has gained a great deal of popularity as it is complete in 5-10 days and typically will more easily fit the lifestyles of active women or those at a great distance from a treatment center. AccuBoost is unique for use in APBI, as it is the only non-invasive breast brachytherapy option available. Typically, with most other techniques a catheter or series of catheters is left in the breast for 10-15 days, creating discomfort and potentially giving rise to infection or other catheter related complications. Treatment centers that offer AccuBoost also have the option of delivering the radiation EITHER once per day for 10 days, or twice per day for 5 days. The choice between these options would be made together between doctor and patient based on her specific needs.

The benefits of AccuBoost®

For APBI
Comfort – Unlike other APBI techniques, with AccuBoost there are NO CATHETERS and all the inconveniences and discomfort associated with them!
Schedule Flexibility (5 or 10 days) – Unlike other APBI techniques, you can receive treatment once a day for two weeks or twice a day for one week.
No Catheter Complications – With no catheters, there is no risk of catheter related infection, displacement or mechanical problems.
No Catheter Care - No Additional care "changing your dressing" at home during the length of your treatment.
Non-Invasive – Non-invasive radiation delivery in a simple outpatient procedure.
Healthy Tissue Sparing - Radiation is delivered parallel to the chest wall sparing unintentional exposure to the heart and lungs.
Conformal - Conformal radiation field matches the target size, shape, and location.
Accuracy - Daily imaging allows your doctor to follow any changes in the target over the course of your therapy.

For Boost
Non-Invasive - Non-invasive radiation delivery in a simple outpatient procedure.
Accuracy - Accurate dose targeting due to daily real-time imaging.
Skin Sparing - Lower skin dose and skin complications.
Toxicity - Less toxicity and better cosmetic results.
Healthy Tissue Sparing - Radiation is delivered parallel to the chest wall sparing unintentional exposure to the heart and lungs.
Conformal - Conformal radiation field matches the target size, shape, and location.
