    Abstract:
    OBJECTIVE: To investigate the role and clinical value of the serum level of hepatocyte growth factor (HGF) and vascular endothelial growth factor(VEGF) in laryngeal squamous cell cancer and the relationship between HGF, VEGF and clinicopathological factors. METHOD: We measured serum HGF and VEGF level in 54 laryngeal squamous cell cancer patients using ELISA to demonstrate the variation of HGF, VEGF level before operation and at day 1, 3, 7, 14 post-surgery. The concentration of the serum HGF, VEGF content in 35 normal healthy people and in 30 vocal cords polyps patients were measured by the quantitative sandwich enzyme linked immunoassay technique. RESULT: (1) The level of serum HGF and VEGF in the patients with laryngeal squamous cell cancer was significantly higher than that of normal healthy people and vocal cord polyps patients (P < 0.01). (2) The level of serum HGF, VEGF in the patients with laryngeal squamous cell cancer was related to clinical stage, differentiation situation, lymph nodes metastasis (P < 0.01), but it was independent of age at diagnosis, gender and tumor location (P > 0.05). (3) There was a significantly positive correlation between preoperative serum VEGF and HGF levels (r = 0.7667, P < 0.01). (4) Post-operational serum HGF levels in 54 laryngeal squamous cell cancer patients who underwent surgical intervention increased significantly, peaked at day 3 after operation. Serum HGF levels of survivors during follow-up period gradually decreased at day 7 and day 14 after operation. The postoperative serum levels of VEGF were decreased significantly than that of preoperation. CONCLUSION: HGF and VEGF may play an important role in the development and progression of human laryngeal cancer. Elevated serum HGF and VEGF levels predict a more aggressive biological behavior in laryngeal squamous cell cancer.
