Epidermal growth factor (EGF) influences the cell by activation of its specific cell receptor (EGFR). It is regarded as one of the most effective mitogenic factors and plays a role in carcinogenesis. The aim of this study was the assessment of EGF expression in different types of cerebral neoplasms and searching for its correlation with histopathologic features of malignancy and presence of peritumoral oedema. Sixty seven samples of brain tumours were examined. Among them were 17 meningiomas, 34 gliomas and 16 metastases. Expression of EGF was estimated by a radioimmune assay. The authors found the presence of EGF in all types of tumours. No correlation was found between expression of EGF and histopathological signs of tumour malignancy, although a tendency appeared towards a higher level of that factor in anaplastic tumours. Also, no correlation was found between EGF and peritumoral oedema. |
