BACKGROUND AND OBJECTIVES: Tumor angiogenesis is an essential process required for growth and metastasis in cancer. Vascular endothelial growth Factor (VEGF) and platelet-derived endothelial cell growth factor (PD-ECGF) are known to be angiogenetic factors. The objectives of this study were to measure the expression of VEGF, PD-ECGF and microvessel density (MVD) in head and neck squamous cell carcinoma (HNSCC) and compare them to normal larynx. We also evaluated relationships of VEGF, PD-ECGF and MVD to clinicopathologic findings in HNSCC.
MATERIAL AND METHODS: The expression of VEGF, PD-ECGF and MVD were evaluated by immunohistochemical staining of 26 cases of HNSCC and 6 cases of normal larynx.
RESULTS
The expressions of VEGF, PD-ECGF and MVD in HNSCC were significantly higher than in the normal control (p<0.05). MVD were significantly correlated with VEGF and PD-ECGF expressions in HNSCC (p<0.05). The VEGF, PD-ECGF expression and MVD correlated with many clinicopathologic findings in HNSCC.
CONCLUSION
These results suggest that VEGF and PD-ECGF are involved in angiogenesis and are related to clinicopathologic findings of HNSCC. Furthermore, we propose that expressions of VEGF, PD-ECGF and MVD to be investigated more in the future as prognostic indicators of HNSCC.
