UC Davis team refines cancer treatments to reduce potential nerve damage
Date:12/15/2008

(SACRAMENTO, Calif.) While radiation treatments deliver precise doses of high-energy X-rays to stop cancer cells from spreading or to shrink tumors, oncologists have become increasingly concerned about inadvertent exposures during head and neck cancer treatments to nerves responsible for upper body mobility. To reduce the possibility of permanent nerve damage, UC Davis Cancer Center researchers have taken the lead in establishing new treatment guidelines for physicians nationwide.

The team, led by Allen Chen, assistant professor of radiation oncology, noticed a trend following treatment for cancers of the tonsil, tongue, throat, and other head and neck organs: A number of patients reported ongoing weakness and sensation problems in their necks, shoulders and upper arms. Chen recognized that these symptoms could be attributed to injury of the brachial plexus nerves, which begin at the back of the neck and extend behind the clavicle and down to the hand. Specific standards for delivering radiation treatments and avoiding this critical body structure, however, did not exist.

"Radiation is an essential treatment for most head and neck cancers, and current technologies make it possible for us to successfully target those tumors," said Chen. "Exposure to other tissues is unavoidable and typically not considered serious or long-term. But brachial plexus damage can be permanent and debilitating, so we decided to develop treatment guidelines to reduce radiation exposure to these nerves."

As a result, Chen and his colleagues established step-by-step techniques for identifying the brachial plexus complex using common anatomical "bench posts" that are easily visible with computed tomography scans commonly used for treatment planning. He then designed delivery contours for intensity-modulated radiation therapy treatments to avoid those areas, and tested the guidelines on 10 patients with a variety of head and neck cancers.
