Abstract

AbstractBackgroundsWe aimed to clarify the outcomes of postoperative radiotherapy (PORT) after salvage neck dissection for cervical lymph node (LN) recurrence in oral cavity cancer.MethodsWe retrospectively evaluated overall survival (OS), recurrence‐free survival (RFS), recurrence patterns, and adverse events of 51 patients with high‐risk features receiving PORT after salvage neck dissection between 2009 and 2019.ResultsAfter a median follow‐up of 7.4 years from PORT initiation, the 7‐year OS and RFS rates were 66.3% (95% CI: 54.0–81.3) and 54.6% (95% CI: 42.1–70.9), respectively. Age <70 years and isolated LN recurrence were significantly associated with longer OS and RFS. Among the 22 patients who experienced recurrence, 14 experienced recurrence within the radiation field. PORT‐related grade 3 acute mucositis (35%) and late adverse events (osteoradionecrosis [4%] and laryngeal stenosis [2%]) were observed.ConclusionsPORT after salvage neck dissection for cervical LN recurrence achieved good survival with acceptable toxicity.
