Circulating vascular endothelial growth factors and their soluble receptors in pre-invasive, invasive and recurrent cervical cancer.

Aim: To study the impact of circulating vascular endothelial growth factors (VEGF) -A, -C and -D and their soluble receptors VEGFR-1/-2 on disease invasion and progression in patients with pre-invasive (CIN), invasive (PCC) and recurrent (RCC) cervical cancer.

Patients And Methods: Blood samples were obtained from 125 women, including 50 cases of CIN, 51 of PCC and 24 of RCC, before treatment. Soluble (s) biomarker levels were determined by ELISA and tested for correlation with histopathological factors.
