FDA OKs advanced computer-based cancer treatment

LIVERMORE, Calif. — The U.S. Food and Drug Administration has cleared the way for the commercialization of an advanced method of targeting tumors with radiation treatment developed by researchers at the U.S. Department of Energy's Lawrence Livermore National Laboratory. The computer-based system, called Peregrine, calculates in 3-D where radiation goes in the body and how much of it is striking tissue, bone or empty cavities. The technology will allow doctors to accurately target tumors with radiation, and to increase the dose needed to destroy tumors without increasing damage to healthy surrounding tissue. NOMOS Corp. (Sewickley, Pa.) has received FDA clearance to produce and market Peregrine systems to the medical community.

Peregrine relies on a mathematical technique called Monte Carlo simulation to track radiation. It simulates the trillions of radiation particles that enter the body during treatment and accurately predicts radiation dosage. Peregrine uses individual patients' CT scans to tailor precise dose calculations for each patient, based on his or her distinct anatomy and disease.

"Peregrine will touch lives," said Christine Hartmann Siantar, principal Peregrine researcher at Lawrence Livermore Labs. "It is a breakthrough technology that can be used in treatment clinics everywhere."
