(0642) Evaluation of Triglyceride-Glucose Index Elevation as a Biomarker and Risk Factor in Laryngeal Carcinoma

Introduction: Insulin resistance is associated with increased levels of IGF-1. IGF-1 has been shown to increase the risk of laryngeal squamous cell carcinoma. The triglyceride-glucose index (TyG index) is a marker of insulin resistance. Our study aimed to investigate the relationship between the TyG index and laryngeal squamous cell carcinoma.

Methods: The study included 53 patients with laryngeal squamous cell carcinoma (Group 1) and 48 healthy volunteers (Group 2). Laryngeal cancer patients were divided into two groups according to their stage. Stages I and II were named Group 1A, and Stages III and IV were called Group 1B. The TyG index was calculated as ln [fasting triglycerides (mg/dL) × fasting plasma glucose (mg/dL) /2]. The effect of the TyG index on laryngeal cancer was investigated on the parameters of sex, age, body mass index, and stage of the disease.

Results: There were no significant differences in age, sex, and BMI between the groups. The TyG index of group 1 (4.75 ± 0.33) was significantly higher than that of group 2 (4.59 ± 0.15). The TyG index value of group 1B (4.84 ± 0.31) was significantly higher than both group 1A (4.61 ± 0.32) and group 2 (4.59±0.15). There was no significant difference between the TyG index values of group 1A (4.61 ± 0.32) and group 2 (4.59 ± 0.15).

Conclusions: The TyG index may be a promising laryngeal squamous cell carcinoma biomarker. People with a higher TyG index may have a higher incidence of laryngeal squamous cell carcinoma and a higher risk of progression.
