Adjuvant radiotherapy improves overall survival for patients with lymph node‐positive head and neck squamous cell carcinoma

Although adjuvant radiotherapy (RT) is often recommended for locally advanced squamous cell carcinoma of the head and neck (HNSCC), its effect on overall or cancer‐specific survival has not been clearly demonstrated. In the current study, the frequency and effect of adjuvant RT on overall survival was investigated in patients with resected lymph node‐positive head and neck cancer.
