Concentrations of Selected Adipokines, Interleukin-6, and Vitamin D in Patients with Papillary Thyroid Carcinoma in Respect to Thyroid Cancer Stages

Abstract EN

The relationships between thyroid cancer and obesity are not fully understood.

Adipokines, proinflammatory cytokines, and vitamin D may mediate these associations.

In this study, we estimated serum concentrations of leptin, adiponectin, chemerin, interleukin-6 (IL-6), and vitamin D in patients with papillary thyroid cancer (PTC).

We searched for associations between the adipokines, IL-6, vitamin D, anthropometric parameters, and TNM AJCC/UICC 2017 classification in 177 patients diagnosed with PTC (151 women and 26 men).

Normal weight patients were predominantly classified as clinical stage I.

The prevalence of stages higher than I was significantly higher in PTC patients with BMI ≥ 25 or with metabolic syndrome.

Using logistic regression waist circumference ≥ 88 cm in women and ≥102 cm in men, upper tertiles of IL-6 and leptin were associated with a higher clinical stage.

There were no differences in the prevalence of microcarcinomas in analyzed groups (BMI ≥ 25 versus BMI < 25 and with metabolic syndrome presence versus without metabolic syndrome).

No significant relationships between serum concentrations of leptin, adiponectin, chemerin, IL-6, vitamin D, and tumor size in PTC were found.

Although insulin resistance represented by the HOMA index was associated with anthropometric variables and with serum leptin, adiponectin, chemerin, and IL-6 concentrations, in our study, no statistically significant relations with PTC staging were identified.
