Littleton 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.

As an NAPBC comprehensive breast cancer center, we believe the Littleton Adventist Hospital IORT program is consistent with our mission to improve care and quality of life for our breast cancer patients. The multidisciplinary program includes breast surgeons, radiation oncologists, medical oncologists, medical physicists, surgical staff, and nurse navigators.

she shares a passion with colleagues to find innovative treatments for
breast cancer patients.
this fall, Littleton Adventist Hospital debuted a new treatment option
for breast cancer patients: intraoperative radiation therapy (IORT).
IORT is a radiation treatment delivered
during a one- or two-step process: either immediately following removal
of a malignant tumor from the breast or in a separate procedure
performed later. Radiation applied for 20 to 30 minutes on the area once
occupied by a tumor helps rid it of cancer.
“The goal of IORT is to improve localized
breast tumor control and increase survival rates for patients with
breast cancer,”says Ellen Buchannan, RN, FNP, CBCN, breast care program
coordinator at Littleton Hospital. “The treatment has been shown to
produce results equivalent to those achieved after several weeks of
wholebreast radiation therapy.”
According to Buchannan, candidates for IORT
are patients older than 45 who have early-stage, invasive, ductal breast
cancerthat has not spread to the lymph nodes.A patient’s tumor must also be smaller than 3 centimeters.
“If a patient decides to have a lumpectomy,
her medical team will present IORT as an option if she meets the
necessary criteria,” Buchannan says. “Radiation is delivered during
surgery or a second procedure; the latter option allows the physician to
be sure the margins left after surgery are free of cancer cells.”
IORT benefits patients by limiting radiation
exposure to healthy structures and minimizing side effects, such as
skin irritation. Instead of having daily radiation treatments for as
many as six weeks, IORT patients undergo a single treatment.
