[Correlation of steroid receptors and growth factors expression with peritumoral edema accompanying cerebral neoplasms].
The aetiology of peritumoral brain oedema still remains unclear, despite investigations, attempted to study the role of various clinical factors and histological features of the tumour. The aim of this investigation was to the evaluate correlation of peritumoral brain oedema with expression of progesterone (PR) and oestrogen (ER) receptors and vascular--endothelial growth factor (VEGF). Eighty nine samples of brain tumours were examined, among them 28 meningiomas, 43 gliomas and 18 metastatic tumours. Expression of steroid receptors was examined with the radioreceptor assay method and expression of VEGF by radioimmune assay. A statistically highly significant correlation was found of VEGF expression with the incidence of diffuse pattern of brain oedema around gliomas and metastatic tumours (p < 0.01). PR expression was associated significantly with the occurrence of localized type of oedema around meningiomas, but in gliomas the expression of this receptor correlated with a diffuse pattern of oedema. No correlation was found between ER expression and peritumoral brain oedema.
