Technology Targets Tumors with Precise Image-Guided IMRT to Spare Healthy

Surrounding Tissue

PALO ALTO, Calif., Sept. 16 /PRNewswire-FirstCall/ -- Doctors at cancer treatment centers in the United States and the Netherlands are now treating head and neck cancer using RapidArc(TM) radiotherapy technology from Varian Medical Systems (NYSE: VAR). RapidArc was used to deliver ultra-precise image-guided intensity-modulated radiotherapy (IMRT) significantly faster than was previously possible with conventional IMRT. The RapidArc treatment plans for these cases also did a better job of protecting surrounding normal tissues and organs.

"Traditional IMRT has been a gold standard for several years in radiotherapy when it came to avoiding healthy tissue and targeting the tumor mass," said Ben Slotman, MD, PhD, professor and chairman of the Department of Radiation Oncology at the VU University Medical Center in Amsterdam, Netherlands. "We have been so satisfied with the faster treatment planning and the faster delivery with RapidArc that we plan to treat all of our head and neck IMRT candidates using this technology."

Slotman and his colleagues recently treated a 46-year old male with throat cancer. "The RapidArc plan showed better and more even tumor coverage, compared with a standard 7-field IMRT plan," said Slotman. "With RapidArc, we were also able to spare more of the organs at risk than with IMRT," he added. When treating a tumor in the head or neck it is important to avoid the highly sensitive organs nearby, such as the spinal cord, eyes, brainstem, and other vital areas of the central nervous system.
