In definitive and adjuvant chemoradiotherapy settings, clinical outcomes were compared between cachexia and non-cachexia patients.Results: Forty patients were diagnosed with cachexia (20.8%). In the definitive setting, overall survival (OS) was significantly shorter in the cachexia group (3-year OS: 50.0% vs 88.5%; p < 0.01), and multivariate analysis identified UICC stage IV, baseline albumin of < 4 and cachexia as poor prognostic factors. However, cachexia was not significant in the adjuvant setting.Conclusion: Cancer cachexia was negatively associated with prognosis in patients with HNC who received definitive chemoradiotherapy. Nutritional intervention during chemoradiotherapy may improve survival in these patients.Keywords: head and neck cancer, squamous cell carcinoma of head and neck, sarcopenia, cachexia, muscle, skeletal, chemoradiotherapy, prognosis
