Local Researcher Seeks to Lower Radiation Risk for Children

ST. LOUIS (KMOX) – A local researcher has found a way to lower the radiation risk for children with a common type of brain cancer.

Medullo blastoma is the most common type of brain malignancy in children — aggressive radiation treatments often cause neurological problems in kids in the future.

Washington University’s Dr. Jeff Michalski hopes to lower that risk by reducing the volume of radiation treatments to a smaller area.

Michalski found you could safely reduce the volume of radiation without compromising the risk of recurrence or the risk of survival in these pediatric patients.

However, trying lower the dose of radiation treatments for children between the ages of 3-7 didn’t work out so well.

“We conclude that it is not safe to reduce the radiation, even in younger children, without risking an increase of occurrence,” Dr. Michalski says.

He says they will keep trying to find out which types of tumors respond better to reduced doses.
