Title: [Expression of VEGF-C and its correlation with cervical lymph nodes metastasis of oral cancers].
Abstract: Vascular endothelial growth factor C (VEGF-C) is known to be capable of inducing cell proliferation of lymphatic endothelia and development of lymphatic vessels. Thus, in the current study the expression of VEGF-C was investigated to understand the mechanism of lymphatic metastasis of oral cancer.VEGF-C protein expression in benign and malignant oral lesions was investigated with an immunohistochemical staining assay, followed by light microscopic examination and image analysis.Immunohistostaining of VEGF-C was observed in normal, benign and malignant epithelia, as well as in some lymphatic vessels. The VEGF-C positive rate was significantly higher in squamous carcinomas than in normal tissues and benign lesions. It was also noted that in squamous carcinomas the expression level of VEGF-C correlated well with pathological grades and stages of lymph node metastasis, but not with clinical grades.These findings suggest that VEGF-C may promote lymphatic metastasis of oral cancer, and it is possible to be used as a predictor for the lymphatic metastasis and prognosis of oral cancer.
