Risk factors for aspiration pneumonia after definitive chemoradiotherapy or bioradiotherapy for locally advanced head and neck cancer: A monocentric case control study

Chemoradiotherapy (CRT) and bio-radiotherapy (BRT) are recognized as standard therapies for head and neck cancer (HNC). Aspiration pneumonia after CRT or BRT is a common late adverse event. Our aim in this study was to evaluate the cause-specific incidence of aspiration pneumonia after CRT or BRT and to identify its clinical risk factors.
