Abstract
Abstract Background Sarcopenia appears to be a negative prognostic factor for poor survival outcomes and worse treatment tolerance in patients with head‐and‐neck squamous cell carcinoma (HNSCC). We evaluated sarcopenia's impact on overall survival (OS), disease‐free survival (DFS) and chemo‐radiation tolerance in patients with head‐and‐neck cancer (HNC) treated with chemoradiotherapy (CRT) from a monocentric observational study. Methods We identified patients with HNC treated by CRT between 2009 and 2018 with pretreatment imaging using positron emission tomography–computed tomography scans (PET/CT). Sarcopenia was measured using the pretreatment PET/CT at the L3 vertebral body using previously published methods. Clinical variables were retrospectively retrieved. Results Of 216 patients identified, 54 patients (25.47%) met the criteria for sarcopenia. These patients had a lower mean body mass index before treatment (21.92 vs. 25.65 cm/m2, p
