IORT for brain cancer
IORT is presently under investigational use as a brain cancer treatment option at CTCA. In order to be a candidate for IORT, patients must be eligible for brain cancer surgery, with a brain tumor that is resectable.
By delivering a single, powerful dose of radiation directly to a tumor site immediately after a brain tumor is removed, while shielding the surrounding healthy brain tissues. Also, IORT helps brain cancer patients finish treatment and get back to their lives quicker by reducing the need for additional radiation treatments.
Helping you maintain your quality of life
Your care team anticipates and proactively manages the side effects of brain cancer radiation therapy. Before, during and after your treatment, you’ll receive integrative oncology services designed to keep you strong, reduce the side effects of radiation, and promote your overall well-being.
What is IORT?
Intraoperative radiation therapy (IORT) delivers a concentrated dose of radiation therapy to a tumor bed during surgery. This advanced technology may help kill microscopic disease, reduce radiation treatment times or provide an added radiation "boost."
Advantages of IORT
Typically, standard radiation therapy involves five days of treatment per week, for a total of five to six weeks for some patients. With IORT, our radiation oncologists can deliver a similar dose of radiation in a single treatment session, while also preserving more healthy tissue. This helps to reduce side effects and the time spent going back and forth to the hospital for radiation treatments.
IORT offers some of the following advantages:
- Maximum effect. IORT delivers a concentrated dose of radiation to a tumor site immediately after a tumor is removed, helping to destroy the microscopic tumor cells that may be left behind. The tumor site is typically at high risk for recurrence and traditional radiation therapy requires a recovery period after surgery, which leaves microscopic disease in the body for longer.
- Spares healthy tissues and organs. During IORT, a precise radiation dose is applied while shielding healthy tissues or structures, such as the skin, that could be damaged using other techniques. This allows a higher radiation dose to be delivered to the tumor bed, while sparing normal surrounding tissues. Critical organs within the radiation field, such as the lungs or heart, can also be protected.
- Shortened treatment times. IORT may help some patients finish treatment and get back to their lives quicker by reducing the need for additional radiation therapy, which is typically given over five to six weeks. The IORT treatment itself takes about four to five minutes.
- A "boost" for traditional radiation patients. Patients who must receive additional radiation therapy following surgery can receive a boost of radiation during IORT. After they have recovered from the surgical procedure, they can continue with their radiation treatments, with typically fewer complications.
A patient must be a surgical candidate in order to be eligible for IORT. This treatment is generally reserved for individuals with early-stage disease.
