7) IMRT SAFE AND EFFECTIVE FOR TREATING CANCERS OF PARANASAL SINUS
Intensity-modulated radiation therapy (IMRT) appears to be a safe and effective treatment for cancers in the nose area, known as paranasal sinus cancers, new data suggest. This is a boon to patients suffering from a cancer that is difficult to treat due to its closeness to the optic nerve and the interactions of air and tissue that can disrupt precision delivery of radiation. Both hold potential for causing blindness.
But clinical outcomes are encouraging from a new collaborative study of 31 patients treated with IMRT at Fox Chase Cancer Center in Philadelphia. Notes Fox Chase lead researcher Aruna Turaka, M.D.: "Our results show there were no loss of vision or vision disturbances such as floaters, and preserving vision is always the main concern."
Researchers found no high grade complications to either vision or salivary function. With a median follow up of 27 months the 2- and 5-year overall survival rates were as high as 89%, for early stages, and declined with time to 66% at 5 years. A few patients had recurrent or residual cancer, but overall, Dr. Turaka says, "IMRT appears be a promising and well-tolerated treatment method."
The presentation "Intensity-Modulated Radiation Therapy (IMRT) for the Para-Nasal Sinus (PNS) Malignancies: Outcomes From Fox Chase Cancer Center (FCCC)" will be at 3:00 p.m. on Sunday, July 18 in the exhibit hall of the Philadelphia Convention Center.
