Varian Medical Systems and BrainLAB to Showcase Novalis Tx(TM) Platform for Non-Invasive Image-Guided Radiosurgery

Powerful Technology for the Non-Invasive Treatment of Cancer on Display at the 45th Annual Society of Thoracic Surgeons (STS) Meeting in San Francisco January 25-27, 2009

PALO ALTO, Calif., Jan. 26 /PRNewswire-FirstCall/ -- A new non-invasive surgical device for eradicating inoperable lung cancer and other conditions is being showcased this week at the 45th Annual Society of Thoracic Surgeons (STS) Meeting in San Francisco. The Novalis Tx(TM) platform from Varian Medical Systems (NYSE: VAR) and BrainLAB enables doctors to perform image-guided radiosurgery on tumors of the lung, as well as of the brain, spine, liver, and prostate, without making a single incision.

Novalis Tx performs stereotactic body radiotherapy (SBRT), a form of non-invasive radiosurgery that uses precisely-shaped and targeted radiation beams to treat tumors and non-malignant growths from outside the body.

"Novalis Tx is a versatile device for performing fast, noninvasive, image-guided radiosurgery," says Naren Ramakrishna, MD, PhD, with Dana Farber/Brigham and Women's Cancer Center in Boston.

Early studies comparing SBRT with conventional radiotherapy - the treatment that is most often prescribed for patients with inoperable lung tumors - suggest that SBRT can result in a better survival rate. Only 10-30 percent of inoperable lung cancer patients who receive conventional radiotherapy survive for five years. While five-year data is not yet available for SBRT, the survival rate at three years has ranged from 54 to 91 percent. These results have encouraged the Radiation Therapy Oncology Group (RTOG), a multi-institutional, international organization that coordinates clinical research in radiation oncology, to sponsor a phase II trial of stereotactic body radiosurgery for the treatment of early-stage lung cancer--both operable and inoperable.

"Preliminary studies suggest that stereotactic body radiation offers us a good chance of achieving 85 to 90 percent local tumor control rates in the treatment of early-stage lung cancer," says Martin Fuss, MD, director of the image-guided radiation therapy program at the Oregon Health & Science University (OHSU). Dr. Fuss began using Novalis Tx to perform radiosurgery on patients with lung and other forms of cancer last October.

About the Novalis Tx Platform

The Novalis Tx platform combines the most advanced technologies available from Varian Medical Systems, the world's foremost provider of medical devices and software for treating cancer, and BrainLAB, a leader in software-driven medical technologies for precise and non-invasive surgical procedures. It incorporates a powerful linear accelerator, which rotates around the patient to target surgical beams at tumors from virtually any angle. A set of sophisticated image guidance and motion management tools provide clinicians with detailed information about the shape, size, and position of the targeted lesion, guide patient set up and positioning, and monitor motion during treatment.

For surgery on moving tumors in or near the lungs, the Novalis Tx includes devices for fine beam shaping and synchronizing treatment with the patient's breathing patterns.

"Using Novalis Tx, clinics can treat twice the number of patients per day than with any other stereotactic radiosurgery system on the market," says Dow Wilson, president of Varian's Oncology Systems business. "The speed and versatility of this technology make Novalis Tx the most cost-effective solution for offering advanced radiosurgical treatments to lung cancer patients and others who can benefit."
