Abstract

Purpose: The objective of this study was to investigate the expression of leptin receptors in benign and malignant tumors of the ovaries and endometrium and its association with body mass index (BMI). Methods: Histological uterine and ovarian samples of normal and neoplastic tissue from 35 patients aged 37-72 years were examined for the expression of leptin receptors with the method of RT-PCR. T. Results: A BMI > 30 was correlated with increased expression of leptin receptors. Both Ra and Rb receptors were expressed in normal and neoplastic tissues. A statistically significant difference in leptin receptor expression was detected between normal and neoplastic tissue, with expression being around 5-fold higher in neoplatic tissue. Conclusion: Endometrial neoplasms and long leptin isoform receptor expression were associated with an increased BMI. A role of long isoform in endometrial carcinogenesis is proposed.
