The relationship of vascular endothelial growth factor and osteopontin expression with 3-year progression-free survival of locally advanced nasopharyngeal cancer patients treated with platinum-based chemoradiation.

Vascular endothelial growth factor and OPN remained potential prognostic predictors in NPC. Patients with positive VEGF and OPN expression in N3, IVB, and neoadjuvant treatment had significantly improved 3-year PFS.
