“…Risk factors for disease recurrence after surgical resection have been reported by multiple authors and include advanced local disease extent (T), incomplete surgical resection, bone invasion, named nerve involvement, positive surgical margins, nodal involvement, and worse histopathologic grading [4,[8][9][10].

As such, radiation therapy has been adopted as a standard of care in patients at high risk for recurrence after surgical resection.…”
