Upregulation of Serum Vascular Endothelial Growth Factor in Patients with Salivary Gland Tumor

Table 1

Serum VEGF level in benign, malignant salivary gland tumors and normal controls as measured by Sandwich ELISA.

Groups	Mean serum VEGF (pg/mL)	𝑃 value
Controls	263.9±310±0.0	Controls versus benign tumors 𝑃=0.03
Benign salivary gland tumor	442.2±343.3	Controls versus malignant tumors 𝑃=0.001
Malignant salivary gland tumor	727.3±441.8	Benign tumors versus malignant tumors 𝑃=0.008
