UNASSIGNED: Abstract Conclusion: The depth of hypopharyngeal superficial @entity5 may predict vessel infiltration and potential risk of cervical lymph node @entity3 . Objectives: To elucidate the histopathological predictors of vessel infiltration and the risk of regional lymph node @entity3 in hypopharyngeal superficial @entity5 . Methods: This study included 31 lesions from 30 @entity1 who had undergone transoral en bloc resection in the hospital. @entity1 with @entity5436 or muscular invasion were excluded. @entity1 characteristics, nodal status, state of vessel infiltration, state of perineural invasion, histopathological parameters, and post-operative cervical lymph node recurrence were retrospectively examined. The histopathological parameters measured were @entity5 diameter and the following three parameters: @entity5 thickness, depth from the mucosal surface, and depth from the basement membrane. Correlations between histopathological parameters and state of vessel infiltration were statistically analyzed. Results: Of the 31 lesions examined, four had vessel infiltration. Three of the four lesions with vessel infiltration had regional lymph node @entity3 as well as subsequent lymph node @entity3 . Lesions with vessel infiltration were significantly deeper than those without. In contrast, there was no significant difference in lesion diameters. In addition, there was no correlation between the depth and the diameter of the lesion.
