Childhood Cancer Survivors at Risk for Stroke

A smiling doctor having a conversation with a little girlSurvivors of childhood leukemia and brain tumors have an increased risk of
stroke later in life, a study shows. This is particularly true for children
treated with radiation therapy to the head at doses greater than 30 Gy.

These findings
justify the continuation of efforts to reduce radiation doses in children being
treated for leukemia or brain tumors when possible, conclude Dr. Daniel C.
Bowers from The University of Texas Southwestern Medical School, Dallas, and
colleagues.

The study, which was
published in the Journal of Clinical Oncology, included 4,828 leukemia survivors
and 1,871 brain tumor survivors. These subjects, who were younger than 21 years
when they were diagnosed between 1970 and 1986, were compared with a group of
3,846 of their siblings.
