Cancer of endometrium (CAE) is the most common gynecologic malignancy in industrialized nations. Increased resistin levels, an adipocytokine produced by adipose tissue and macrophages, have been considered as a risk factor in gastric, colon and breast cancer, recently. No studies associating resistin levels with endometrial cancer have been done so far. The purpose of this case-control study was to determine the relationship between serum circulating resistin levels and resistin gene -420C>G (rs3219175) variant in endometrial cancer patients. 37 Caucasian female patients and 39 healthy controls were enrolled in this study. Difference in resistin levels between age and BMI matched patients group (mean 24.2 ng/ml) and control subjects (mean 10.1 ng/ml) were statistically significant (p <001). We also determined single nucleotide polymorphism -420C>G (rs3219175) within resistin gene and no significant association between resistin levels and investigated polymorphism was found. Furthermore, no significant association between higher resistin levels and diabetes mellitus 2, body mass index, smoking or age have been observed within studied groups. To our knowledge, this is the first study examining the relationship between serum resistin levels and endometrial cancer and our results show, that patients with endometrial cancer have significantly increased circulating levels of resistin compared to control subjects.
