Serum vascular endothelial growth factor in patients with nonmelanoma primary ocular malignancies: A possible potential biomarker of tumor progression and poor prognosis
Context: Vascular endothelial growth factor (VEGF) is a potent and specific angiogenic growth factor that may participate in the formation of the vascular tumor stroma. Pretreatment VEGF levels can be a biomarker to predict tumor progression and prognosis in patients with primary ocular malignancies. Aims: The aim of t …
