Correlation of VEGF and Ki-67 Expression with Histopathological Features and WHO Grade in Meningioma: A Cross-sectional Study.
BACKGROUND Meningiomas, the most common primary central nervous system tumors, exhibit variable clinical behavior. While World Health Organization (WHO) grading is standard, complementary biomarkers are needed to refine prognostication. Vascular Endothelial Growth Factor (VEGF) and Ki-67 are potential indicators of ang...
