Abstract:
BACKGROUND AND OBJECTIVES: Normal angiogenesis occurs as a part of the body's repair processes like the healing of wounds and fractures. By contrast, uncontrolled angiogenesis can often be pathological. Vascular remodelling could therefore play an important role in the growth process of solid tumors. The aim of this study was to detect the expression of platelet-derived endothelial cell growth factor (PD-ECGF), basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF), and investigate the correlation between these factors. Also, we studied the relationships between the expressions of these factors and the clinical stage, nodal involvement, and histologic grade in the squamous cell carcinoma of larynx. MATERIALS AND METHOD: The authors examined the expression of three angiogenic factors in specimens of laryngeal squamous cell carcinoma (n=17). The mRNA expressions of angiogenic factors were detected by the semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Statistics were analysed using the Fisher's exact test, the Wilcoxon signed rank test, and the Spearman correlation coefficiency. RESULTS: PD-ECGF and bFGF were significantly higher in the stages III and IV cancers than in the stages I and II cancers, and thus shows that bFGF was related to severity of the nodal involvement. The expression of more than one factor was significantly related with stages III and IV cancer. PD-ECGF and VEGF were related with each other. CONCLUSION: The authors suggest that angiogenic factors, especially, PD-ECGF and bFGF, may be used as prognostic factors for the squamous cell carcinoma of larynx.
