Relationship between intratumoral hemorrhage and overexpression of vascular endothelial growth factor (VEGF) in pituitary adenoma.

Abstract

The authors investigated the relationship between hemorrhage and the expression of vascular endothelial growth factor (VEGF) in pituitary adenomas. The subjects were 39 patients with pituitary adenomas. Surgically obtained tumor tissue was immunohistochemically stained using antibodies against VEGF, CD-34, Ki-67, and anterior pituitary hormones.
