What is intraoperative Radiation Therapy (IORT)

IORT is a method for delivering radiation directly to the tissue surrounding the area from which a tumor has been removed (tumor bed). This approach is highly precise, sparing normal tissue, effectively radiating the area in one session and significantly reducing the disruption to your life.

By contrast, traditional regimens of external beam radiation therapy may consist of 10- to 15-minute sessions five days per week for three to six weeks.

Parkridge Medical Center offers breast IORT. The surgeon and radiation oncologist collaborate to evaluate patients and determine if they are eligible for IORT.

How does IORT work?

After the surgeon removes the cancerous tumor from the breast, IORT is used to deliver low-energy, high-dose radiation to the tumor bed. Although IORT uses a smaller dose of X-rays than standard radiation therapy, the entire regimen of radiation is delivered as part of the lumpectomy procedure in the operating room while the patient is under anesthesia.

Is IORT effective?

Studies to determine the efficacy of IORT in preventing breast cancer recurrence have shown that IORT is an effective modality for curing breast cancer and preventing recurrence years after treatment.

Do I qualify for IORT?

IORT is an excellent option for patients who are:

  • 50 years of age or older
  • Diagnosed with early stage breast cancer
  • Candidates for surgical resection of a tumor
