Adventist Hospital introduced Colorado’s first Intraoperative Radiation
Therapy (IORT), an innovative form of radiation therapy for breast
cancer patients with small, early-stage tumors. The treatment is called intraoperative radiation therapy because
it can be given during a lumpectomy operation shortly after the tumor
is removed. IORT can also be done as a second procedure if a patient
prefers to have a lumpectomy at another hospital and then come to
Littleton Adventist Hospital for the radiation portion of the treatment.
The localized procedure, which is
administered for 20 to 30 minutes, delivers radiation precisely to the
tumor site with minimal exposure to surrounding tissues, which are
shielded during the IORT. The procedure destroys microscopic tumor
cells, reducing the risk that tumor cells will grow back.
Littleton Adventist Hospital chose the Zeiss INTRABEAM®
IORT system because it is backed by more than 13 years of successful
clinical use, having treated more than 8,000 patients with early breast
cancer. The system was also used in the highly reputable TARGIT-A Trial.
The TARGIT-A Trial is the largest randomized clinical trial in the
field of IORT. After the trial, researchers concluded that INTRABEAM
IORT (concurrent with lumpectomy) should be considered as an option for
certain patients with breast cancer as an alternative to postoperative
traditional external beam radiotherapy (EBRT).
Compared to EBRT, INTRABEAM IORT offers
several significant advantages: It directly targets the tumor bed with
radiation, while minimizing radiation to healthy tissue; it can be
administered concurrently with the lumpectomy, allowing less time for
tumor cells to grow back; it can be administered in one day so it offers
the potential for significantly faster recovery time and a return to
your every day activities sooner; and it can be used in conjunction with
a standard EBRT regimen as an additional boost treatment. Benefits of
boost treatments include: very low recurrence rates, low rate of side
effects, and very good cosmetic results.
Compared to EBRT, Zeiss INTRABEAM® IORT offers the potential for:
