UNASSIGNED: External beam radiotherapy (EBRT) is not a first line treatment in @entity259 ( @entity259 ), but is recommended as an adjuvant treatment in certain cases. The evidence for EBRT in @entity259 is limited. A comprehensive literature search was performed. Data on @entity1 demographics, disease stage, treatment characteristics, and outcomes were collected from included articles after quality appraisal. Sixteen articles met the inclusion criteria, with a pooled population of 5114. Only 1 study was prospective and there were no randomized controlled trials. Most of the evidence suggests that EBRT improves locoregional control in @entity1 at high risk of locoregional recurrence. This was corroborated by analysis of pooled @entity1 data. Available evidence suggests an improvement in locoregional control when EBRT is used in @entity1 over the age of 45 at high risk for locoregional recurrence. However, there is a need for long-term prospective multicenter research on the subject.    2015 Wiley Periodicals, Inc. Head Neck 38: E2297-E2305, 2016.
