The association between skeletal muscle mass and sensorineural hearing loss upon cisplatin-based chemoradiotherapy in patients with head and neck squamous cell carcinoma

Abstract

Introduction: Patients with head and neck squamous cell carcinoma(HNSCC) treated with cisplatin-based chemoradiotherapy (CRT) frequentlyexperience irreversible sensorineural hearing loss (SNHL). Patients with lowlumbar skeletal muscle index (LSMI) may experience higher serum peak dos-ages of cisplatin. This study investigated whether pre-treatment low LSMI isassociated with increased SNHL upon cisplatin-based CRT.Materials and methods: LSMI was assessed using routine pre-treatment CTscans. Pure tone audiometry was performed at baseline and at follow-up toassess treatment-related SNHL. Linear mixed models were used to reveal apotential association between the continuous variable LSMI and SNHL.Results: This retrospective cohort study included 81 patients and found a significantassociation between low LSMI and increased treatment-related SNHL at pure tone fre-quencies vital for the perception of speech (averaged of 1, 2, and 4 kHz) (p = 0.048).Conclusions: HNSCC patients with low LSMI suffer increased treatment-related SNHL upon cisplatin-based CRT.
