title: Expression of granulocyte colony-stimulating factor receptor and platelet-derived endothelial cell growth factor in oral and oropharyngeal precancerous lesions.
abstract: Epithelial hyperplasia and dysplasia have been diagnosed as precancerous lesions and have been discussed in relationship to carcinogenesis. We analyzed the immunohistochemical expression of granulocyte colony-stimulating factor receptor (G-CSFR) and platelet-derived endothelial cell growth factor (PD-ECGF) in oral and oropharynx; 33 samples of normal epithelium, 28 samples of hyperplasia, 16 samples of dysplasia and 58 samples of squamous cell carcinoma. Also, we examined mean vessel density (MVD) by using CD34 staining and proliferating cell nuclear antigen (PCNA) staining. Dysplasia and head and neck Squamous Cell Carcinoma (SCC) exhibited higher G-CSFR expression and MVD than normal or hyperplastic epithelium (p <0.01). In the PD-ECGF staining, significant differences were found between SCC and normal epithelium, hyperplasia and dysplasia (p<0.001). In dysplasia and hyperplasia, PD-ECGF expression was significantly correlated with PCNA expression (r=0.345, p=0.025), however it was not correlated with the MVD. G-CSFR expression was not correlated with either PCNA or MVD. These results suggest that G-CSFR and PD-ECGF might be concerned with different carcinogenesis pathways of the squamous cells in the oral region and that PD-ECGF may be concerned with epithelial proliferation rather than angiogenesis.
