Meningiomas occur at a rate of about five to eight cases per 100,000 people per year. The five-year survival rate for meningioma is 63 percent.
“This is an important finding since there are few known risk factors for meningioma and the ones we do know about are not things a person can change,” said meta-analysis author Gundula Behrens, PhD, of the University of Regensburg in Regensburg, Germany. “Given the high prevalence of obesity and the unfavorable prognosis for this type of tumor, these findings may be relevant for strategies aimed at reducing the risk of meningioma.”
The meta-analysis looked at all of the available research on body mass index (BMI), physical activity and the brain tumors meningioma and glioma, which are the most common primary brain tumors in adults. A total of 12 studies on body mass index and six on physical activity were analyzed, involving 2,982 meningioma cases and 3,057 glioma cases.”
