BACKGROUND. Vascular endothelial growth factor (VEGF) and VEGF- C play a crucial role in the regulation of tumor growth and metastasis. The current study examined the significance of serum VEGF and VEGF-C levels in relation to conventional clinicopathologic parameters, response to treatment, and survival in patients with cervical carcinoma. METHODS. Between December 1999 and March 2004, serum VEGF and VEGF-C levels were analyzed in 78 patients with cervical carcinoma undergoing primary treatment (primary surgery [n = 40] and radiotherapy [n = 38]), as well as in 30 healthy controls. Serum VEGF and VEGF-C levels were assessed by enzyme-linked immunosorbent assay before and within 2 weeks after treatment. RESULTS. Serum VEGF and VEGF-C levels were higher in patients with cervical carcinoma than in the healthy control (P = 0.0002 and P = 0.0007, respectively). Both VEGF and VEGF-C concentrations increased significantly in patients with squamous cell carcinoma (SCC vs. normal control: P < 0.0001 and P = 0.0001, respectively), but not in adenocarcinoma (vs. normal control: P = 0.2982 and P = 0.7766, respectively). In an analysis of SCC, the pretherapeutic serum levels of VEGF and VEGF-C correlated significantly with advanced International Federation of Gynecology and Obstetrics stage and large tumor size, but not with lymph node metastasis. The pretherapeutic serum level of VEGF-C also correlated significantly with disease recurrence or persistence after treatment. Both serum VEGF and VEGF-C levels decreased significantly after treatment. CONCLUSIONS. The serum levels of both VEGF and VEGF-C have potential usefulness as biologic markers of SCC of the uterine cervix. (C) 2005 American Cancer Society.
