Prognostic impact of elevation of vascular endothelial growth factor family expression in patients with non-small cell lung cancer: an updated meta-analysis.

Background: The vascular endothelial growth factor family has been implicated in tumorigenesis and metastasis. The prognostic value of each vascular endothelial growth factor family member, particular VEGF/ VEGFR co-expression, in patients with non-small lung cancer remains controversial.

Materials And Methods: Relevant literature was identified by searching PubMed, EMBASE and Web of Science.
