Estrogen and Progesterone receptors in Meningioma

ABSTRACT

We studied the status of estrogen(ER) and progesterone(PR) receptors in meningiomas removed from 32 patients, using immunoperoxidase(IP) assays. PR were detected in 72% of the cases & ER were detected in 31%. The possible correlation between age, sex, histological type, ploidy pattern and proliferation index values with steroid receptor activity were discussed. The date suggest that the majority of meningiomas contain high affinity receptors for progesterone, that estrogen receptors are present in only a few meningiomas.
