Brain tumors are a diverse group of neoplasms arising from different cells of the central nervous system. Although brain tumors account for only 2 percent of all cancers, these neoplasms result in a disproportionate share of cancer morbidity and mortality of 5.8 per 100,000 population (annual age-adjusted mortality rate in the US 2008-2012). My lab focuses on the causes and biological differences of adult meningioma.

Meningiomas account for almost 40% of all primary brain tumors with 2.5 times higher occurrence in women and African-Americans compared with men and other ethnicities. The total number of meningioma patients who fail treatment or experience uncontrolled local recurrence represent roughly two-thirds of all meningioma patients. Even benign meningiomas are lethal if located in an inaccessible region. Over the past decade, Dr. Patel’s and my lab have been first to discover the three true biological groups that give rise to meningioma, with one being exclusively responsible for the most aggressive type of meningioma. Our studies have been independently validated by multiple other laboratories, which has led to close collaborations throughout the world.

We are part of the International Meningioma Database and contribute as editors to BMC Cancer and Frontiers in Neuroscience.
