title: Estrogen and progesterone receptors in meningiomas.
abstract: Estradiol and progesterone receptors were studied in 14 patients with meningiomas. Estrogen receptors were detected by specific monoclonal antibodies, whereas progesterone receptors were assayed by the dextran-coated charcoal method. In 9 cases the estrogen receptors were also investigated in cultured tumor cells. Positive estrogen and progesterone receptors were found in 86% of patients. The results have been compared with 11 published series of sex steroid assays in meningiomas. The different rate of positive results in most series can be explained by preoperative glucocorticoid therapy. There is no correlation between the estrogen and progesterone receptor activity, the sex and age of the patients, and the location and histological features of the meningioma. The authors suggest that assays of antiestrogen and antiprogestin drugs in cultured cells can indicate whether this estrogen and progesterone receptor activity may be of therapeutic use.
