Adipokines, myokines and cytokines in endometrial cancer patients: relations to obesity phenotype of excessive body mass and features of the tumor
Aim. To study serum content of a number of known adipokines, myokines and cytokines and compare obtained data with overweight phenotype and characteristics of tumor in untreated patients with endometrial cancer (EC) Materials and methods. The study included 88 patients with a mean age 60.08±0.67 years and a mean body mass index (BMI) 32.90±0.83. Patients were subjected to anthropometry and analysis of laboratory parameters, including serum level of leptin, adiponectin, omentin, prefilin (Pref-1), myostatin, irisin, IL-6 as well as insulinemia and insulin resistance index (HOMA-IR). On the basis of combination of anthropometric and laboratory data patients with overweight (BMI >25.0) were subdivided into the groups with "standard" (S) and conditionally "metabolically healthy" (MH) phenotype. Results. Levels of leptin, insulin and adiponectin in the serum of patients with EC are associated with BMI value and demonstrate significant differences between S and MH groups. Levels of prefilin, myostatin, and IL-6 are not associated with an increase in BMI, but are also different in patients with S and MH phenotype of overweight.For levels oа irisin, omentin, and TNF-alphathere is no peculiar dependence both, the BMI, and of belonging to a group with S or MH phenotype. Omentin level in the serum is associated with less favorable tumor differentiation (MH group), while IL-6 level - with a more advanced stage of the tumor (all patients and group S). Conclusion. Adipokines, myokines and cytokines circulating in blood of EC patients vary in their connections with BMI or with "standard" or "metabolically healthy" phenotype of its excess. They vary also in relation to EC features, which in sum may have practical importance.
