| description | Brain gliomas are characterized by invasive growth and neovascularisation potential. Angiogenesis plays a major role in the progression of gliomas and its determination has a great prognostic value. The aim of the study was to assess the vascularisation of chosen brain gliomas and to estimate how it is correlated with tumour histological type, malignancy grade, location and size, and with age and sex of patients. Tumour vascularisation analysis was based on the determination of microvascular proliferation (MVP) and microvessel density (MVD). Microvascular proliferation was measured with immunohistochemical methods using mouse monoclonal antibodies to detect cell proliferation antigens. The following antibodies were used Ki-67 and PCNA (DAKO). Identification of vessels was performed by CD31 antibody and anti-human von Willebrand factor (DAKO). The highest microvascular proliferation and microvascular density were observed in multiform glioblastomas and the lowest in oligodendrogliomas. Significant correlation was observed between the vascularisation and malignancy grade. |
