Prognostic value of microvessel density and its correlation with clinicopathological features in human olfactory
Abstract:
Although angiogenesis plays an important role in tumor growth and invasion, its role in the progression of olfactory neuroblastoma (ONB) has rarely been published. The aim of the present research was to analyze the prognostic role of microvessel density (MVD) in ONB and its association with clinicopathological parameters. 70 ONB cases were assessed for immunohistochemical expression of CD31, CD34, CD105, VEGF, and VEGFR2. The expression of CD105-MVD was negatively associated with histological grade and tumor Kadish stage, and its expression was positively correlated with the expression of VEGF/VEGFR2. Low expression of CD105-MVD and high tumor histological grade were strongly associated with poor survival. Thus, CD105-MVD was demonstrated to be a valuable independent prognostic indicator for ONB. MVD is expected to be useful as an important marker to distinguish tumor histological grade.
