The chicken pox is one of those pesky illness that affects kids and pains their parents, but it may offer some positive health benefits later in life, experts believe – a reduced risk for developing glioma.
In one of the largest studies to date, an international consortium led by researchers in the Dan L Duncan Comprehensive Cancer Center
at Baylor College of Medicine reported an inverse relationship between a
history of chicken pox and glioma, a type of brain cancer, meaning that
children who have had the chicken pox may be less likely to develop
The Baylor team led by Dr. Melissa Bondy, a McNair Scholar and
associate director for cancer prevention and population sciences at
Baylor, and Dr. E. Susan Amirian, assistant professor in the Duncan
Cancer Center at Baylor, reported their results in the journal Cancer Medicine.
In the study, the team reviewed information from the Glioma
International Case-Control Study is a large, multi-site consortium with
data on 4533 cases and 4171 controls collected across five countries.
They found a 21 percent reduced risk of developing glioma with a
positive history of chicken pox. Furthermore, they identified the
protective effective was greater in higher grade gliomas.
The large study validates earlier studies showing this link, Bondy
said. “It provides more of an indication that there is some protective
benefit from having the chicken pox,” she said. “The link is unlikely to
In the future, scientists may be able to apply the chicken pox vaccine to brain cancer research.
