Meningiomas are the most common primary brain tumor in adults, however, in comparison to other tumors, they are extremely understudied. The International Consortium on Meningiomas, under the leadership of Dr. Gelareh Zadeh, has been formed in order to increase awareness and conduct high quality cutting-edge research on these highly understudied tumors. The Consortium has representatives from 30 institutions across 4 continents with expertise ranging across the fields of neurosurgery, neuropathology, neuro-oncology, neuro-radiology, radiation oncology, molecular/translational biology, bioinformatics, and statistics/epidemiology. The Consortium meets regularly by teleconference as well as through face-to-face meetings to discuss, collaborate, and present progression on ongoing projects as well as plan for international conferences, workshops, educational days, and special issue publications.
