Planned neck dissection (ND) was the historical standard of care after definitive radiation for head and neck cancer due to moderate rates of residual nodal disease in patients with positive nodes at diagnosis [1,2]. However, routine post-radiation neck dissection may subject patients with pathologic complete response in the neck to the morbidity of surgery without any added benefit. During the 1990s, concurrent chemotherapy with radiation was shown to significantly improve outcomes, ushering a paradigm shift with increased usage of nonoperative definitive chemoradiation (CRT), especially in the setting of oropharyngeal and laryngeal cancer [3].
