Lack of correlation between microvascular density and pathological features and outcomes in XXXX .

Unlike its cutaneous counterpart, prognostic markers for primary @entity320 have not been well elucidated. It has been recently demonstrated that microvascular density (MVD) in @entity320 has a significant negative correlation with survival; however, this has not been well-studied in @entity320 of the head and neck. This study explores the potential association between MVD, various histological parameters, and the outcome of a series of @entity3136 . Nineteen such cases were immunostained with @entity2279 and the MVD was calculated by using Bioquant Image Analysis Software (R and M Biometrics, Nashville, @entity7443 ). These cases included 16 sinonasal and 3 oral @entity5 . The 1, 2, 3, 4 and 5  years overall survival rates were 75, 57, 61, 46 and 46%, respectively. The MVD of the @entity5 ranged from 25.7 to 732 vessels/mm(2) (mean 142.8 vessels/mm(2); median 84.7 vessels/mm(2)). There was no significant correlation between the MVD and the different clinicopathological features seen within the @entity5 . There was also no correlation between the MVD and relapse free and overall survival. The results of this study suggest that MVD does not correlate with outcome in @entity320 of the head and neck as seen in cutaneous @entity320 . Further larger studies are needed to identify predictive and prognostic markers in such @entity320 .
