Immunohistochemical expression of vascular endothelial growth factor correlates with positive surgical margins and recurrence in T1 and T2 squamous cell carcinoma (SCC) of the lower lip (Journal article)

Kyzas, P. A./ Stefanou, D./ Agnantis, N. J.

Tumor angiogenesis is associated with tumor progression and aggressiveness in a number of malignancies, and vascular endothelial growth factor (VEGF) is considered as a leading candidate in this process. The aim of the present study was to investigate the role of VEGF immunohistochemical expression and tumor angiogenesis in predicting local recurrence in surgically treated lip SCC. We performed a retrospective analysis of 50 patients with lip SCC in order to investigate whether VEGF immunohistochemical expression and tumor angiogenesis correlate with clinicopathologic parameters and outcome. Tumor angiogenesis was estimated by determining microvessel density (MVD) with the use of CD34 antibody. Our results showed that VEGF was strongly correlated with tumor invasion towards the surgical margin. There was also a significant association of high VEGF expression with a higher incidence of local recurrence (p < 0.001). We suggest that VEGF expression may be used as an index to distinguish patients with higher risk of relapse.
