Resumo: PURPOSE: To evaluate the relationship between microvascular density and the expression of vascular endothelial growth factor (VEGF) and KIT as possible markers of angiogenic stimulus in astrocytic tumors and correlate it with histopathological grading. METHODS: We enrolled 99 surgical specimens of supratentorial astrocytic tumors for analysis of VEGF and KIT and subsequent correlation with MVD and grading. RESULTS: KIT and VEGF expression correlated with microvascular density (p<0.005) and both VEGF and microvascular density correlated with grading (p<0.005). KIT had no significant relationship with grading (p=0.657). CONCLUSION: KIT and VEGF constitute important pathways in the angiogenesis of astrocytomas and therefore are promising prognostic tools and options for therapeutic intervention.
