IntraOp to Highlight Single-Dose IOERT Breast Cancer Study

September 3, 2008 - IntraOp will discuss at ASTRO 2008 the recent results of the study which found that a single dose of Intraoperative electron radiotherapy (IOERT) delivered in a single day may be equivalent to six weeks of standard, daily radiation for breast cancer patients.

According to the study, led by by Umberto Veronesi, M.D., director of the European Institute of Oncology in Milan, Italy, a breast surgeon who has pioneered the use of IOERT for this purpose, a single dose of intraoperative electron-beam radiation can be equal to the traditional six-week course for women with breast cancer. The only FDA-approved device available in North America that is capable of delivering the IOERT treatment extolled by Dr. Veronesi in an unshielded operating room is IntraOp’s Mobetron. The Mobetron is a fully portable, self-shielded linear accelerator that can be used in an existing operating room.

Dr. Veronesi presented the results from the first findings of his randomized trial at the recent ISIORT conference in Madrid, Spain, in June 2008. Patients were divided into two groups that received one of two types of treatment: breast conserving surgery and a single dose of IOERT; and breast conserving surgery and traditional six weeks of post-operative radiation therapy. Dr. Veronesi’s study reported that, to date, women who received a single dose of IOERT had identical control, survival and cosmetic results as those who underwent the standard six-week radiation regimen.

From these results, Dr. Veronesi concluded that a single dose of IOERT may be equivalent in outcome to six weeks of post-operative radiation therapy.
