Abstract

Hypopharyngeal cancer is a common malignant disease among head and neck cancers. This restrospective cross-sectional study included 67 patients with hypopharyngeal cancer who underwent concurrent chemoradiotherapy from January 2019 to January 2024 at K Hospital. The objective of the study was to evaluate the prognostic value of pre-treatment PET/CT imaging parameters, specifically SUVmax and metabolic tumor volume (MTV), for overall survival in patients receiving concurrent chemoradiotherapy. The findings demonstrated that SUVmax ≥ 15.5 or MTV ≥ 11cm³ were independent prognostic factors for overall survival, regardless of tumor stage or location, with corresponding hazard ratios (HRs) of 3,21 (p = 0.003) and 2.02 (p = 0.025), respectively.
