Hormonal dependency of cerebral meningiomas

Though meningiomas are benign intracranial tumors, a minor group invades the skull base and the connective tissue of the sinus cavernous inducing neurological deficits. These patients can not be cured by surgical treatment. Therefore, the development of an adjuvant medical therapy has been the goal during the last decade. We report here on different medical concepts which are based on steroids, amines, growth factor antagonists and cytokines. In addition, our data give evidence that the growth of intracranial meningiomas is under multifactorial proliferative control.
