Meningiomas are begnin tumors of central nervous system. They have high rates of relapse and sometimes are not amenable to total removal mainly when involve vital structures. Clinical, epidemiological, biochemical and "in vitro" experiment show evidence that meningioma growth is influencied by steroid hormonal medium. Several clinical trials have explored these meningioma characteristics with the use of substances interfering with steroid actions: RU486 (antiprogestinic and antiglucocorticoid), medroxiprogesterone acetate (antiprogestinic), gestrinone (antiestrogenic e antiprogestinic), tamoxifen (antiestrogenic) and buserelin (LHRH superagonist), beyond of octreotide (somatostatin analog) and bromocriptine (dopaminergic agonist). Other substances have potential for the meningiomas treatment: aminogluthetimide, suramin and trapidil. In this review, we analyzed the literature about these aspects.
