“…Supporting evidences were obtained from previous works on head and neck cancer, multiple myeloma, basal cell carcinoma, and Kaposi's sarcoma (Aoki et al, 1999;Dankbar et al, 2000;Jee et al, 2001). VEGF is a potent angiogenic factor that is pivotal in the transition from an avascular tumor to a vascularizing phenotype tumor (Ferrara and Davis-Smyth, 1997). VEGF expression has been reported to be associated with the progression of cervical intraepithelial neoplasia (Guidi et al, 1995;Dobbs et al, 1997), the angiogenesis and early invasion of cervical cancer, and the prognosis of patients with early-stage cervical cancer (Kodama et al, 1999;Cheng et al, 2000).…”
