Aspiration pneumonia is one of the most important side effects of chemoradiotherapy (CRT) and bioradiotherapy (BRT) in patients with head and neck cancer (HNC). Aspiration pneumonia can lead to cancer-related mortality in HNC patients. However, the relationship between aspiration pneumonia occurring during CRT or BRT for HNC and treatment outcomes in HNC patients is not well characterized. | Risk factors for aspiration pneumonia during concurrent chemoradiotherapy or bio-radiotherapy for head and neck cancer
