Abstract

It is unknown whether the presence of metabolic syndrome (MetS) affects the incidence of laryngeal cancer. The aim of this national population-based retrospective study was to analyze the relationship between MetS and the incidence of laryngeal cancer. Patients with laryngeal cancer (ICD-10: C32) between 2009 and 2010 were retrospectively identified and tracked until 2015 using the Korean Health Insurance claims database. During the seven-year follow-up period, 5,322 subjects were newly diagnosed with larynx cancer. The mean age of people with laryngeal cancer was much higher than those without (63.29 vs. 47.7 years, p < 0.0001), and the incidence of larynx cancer in men was much higher than that in women (93.16% vs. 6.84%, p < 0.0001). Age, gender, smoking status, alcohol intake, and exercise-adjusted hazard ratios indicated that participants with MetS had a 1.13-fold higher hazard of having larynx cancer than those without MetS. The number of MetS components was a strong risk factor for laryngeal cancer with a higher risk estimate of this cancer in both ex- and current smokers as well as people who have never smoked. MetS was found to be an independent risk factor for the incidence of laryngeal cancer. In Korea, MetS and its components are significantly associated with the development of laryngeal cancer.
