How is intraoperative radiation therapy used to treat ovarian cancer?

Intraoperative radiation therapy (IORT) allows ovarian cancer patients to receive a single, powerful dose of radiation directly to a tumor site during surgery.

Typically, standard radiation therapy involves five days of treatment per week, for a total of five to six weeks. With IORT, 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 minimize the time spent going back and forth to the hospital for radiation treatments.

A patient must be a surgical candidate in order to be eligible for intraoperative radiation therapy. Also, this treatment is generally reserved for individuals with early stage disease.
