Hormones and tumours in central nervous system (CNS): steroid receptors in primary spinal cord tumours.

Abstract
On the basis of the studies reported on steroid receptors in brain tumours, cytoplasmic and nuclear estrogen (ER) and progesterone (PR) receptors have been examined in forty primary spinal cord tumours: fifteen neurinomas, three neurofibromas, nine meningiomas, nine ependymomas, two astrocytomas, one oligodendroglioma and one hemangiopericytoma with the exchange method in the presence of sodium thiocyanate for ER and using the synthetic progestin R5020 for PR. Regardless the type of the tumour, ER have been detected with a higher incidence in male than in female patients (78% versus 59%). PR had the same incidence in male and in female patients. The neurinoma was the oncotype more constantly provided with steroid receptors: nuclear ER, in fact, has been found with an incidence of 75% in male and of 43% in female patients. This oncotype is usually provided in both sexes with PR. Ependymomas is spinal tumour with the highest incidence of cytosol ER both in male and in female patients. On the basis of the above results reported it can be assumed that hormonal factors might be involved in the occurrence as well as in the growth of spinal cord tumours. Therefore it can be hypothesized that hormonal treatment might favourably be used as an adjuvant therapy in some selected patients with receptor positive spinal tumours.
