IntraOp Medical Delivers Third Mobetron, Advanced Intraoperative Electron Radiation Therapy System, to Japan

19th Mobetron Unit Delivered Worldwide

SUNNYVALE, Calif.--(HSMN NewsFeed)--IntraOp Medical Corporation (OTCBB: IOPM ), a provider of innovative technology solutions for the treatment and eradication of cancer, today announced it has delivered Mobetron® to the Gunma Prefectural Cancer Center in Japan. Mobetron is a proprietary, mobile, self-shielded device designed to deliver intraoperative electron-beam radiation therapy (IOERT) to cancer patients during their tumor removal surgery. With this delivery, IntraOp has delivered 19 Mobetron units worldwide, including three in Japan.

Gunma Prefectural Cancer Center is one of 80 hospitals in Japan with active IOERT programs. Although Japan is considered the birthplace of modern IOERT, the Center, like almost all Japanese centers, presently transports the patient, in the midst of surgery, from the operating room to the radiation department to receive the IOERT treatment. Mobetron, by contrast, is self-shielded and delivers IOERT in the operating room, without patient transportation. The Gunma unit and Mobetron delivered to Nagoya University Hospital in September 2006 are the first two IOERT systems in the country to be located in a standard operating room.

"We have been working diligently with our partner in Japan, Chiyoda Technol Corporation, to introduce Mobetron's modern IOERT technology to Japan, and we are gratified that these efforts are beginning to bear fruit," said Dr. Donald A. Goer, President and Chief Executive Officer of IntraOp. "Mobetron allows treatment to be delivered more cost effectively and conveniently than the Center's current IOERT method, making IOERT treatment more routinely available to a greater proportion of the Center's patients. We believe other hospitals in Japan are likely to follow the example of Gunma and Nagoya."

With Mobetron, radiation and surgical oncologists can pinpoint the exact area that requires radiation and immediately deliver high doses directly to the affected tissue during cancer surgery. Hospitals can wheel Mobetron between existing operating rooms without the costly renovations required to accommodate traditional radiation therapy devices. Key patient benefits of this early and powerful start to radiation therapy include: increased survival rates, better local tumor control, shorter treatment cycles, and fewer side effects.
