Meningioma molecular profile reliably predicts tumor recurrence

Although typically benign, about one-fifth of meningiomas, the most common primary brain tumors, recur despite complete surgical removal. The current meningioma classification does not consistently predict whether the tumor will recur, but researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital report today in the Proceedings of the National Academy of Sciences that using molecular profiles that might better predict meningioma recurrence.
