Clinical outcomes after local field conformal reirradiation of patients with retropharyngeal nodal metastasis

The purpose of this study was to present our experience with retropharyngeal node reirradiation using highly conformal radiotherapy (RT).A retrospective screen of 2504 consecutively irradiated patients with head and neck malignancies between 2005 and 2015 identified 19 patients who underwent reirradiation for retropharyngeal node metastasis. Clinical and toxicity outcomes were assessed in these patients.Thirteen patients (68%) had squamous cell...
