title: [Serum adipokines and their receptors in endometrial and colon cancer patients: relationship with tumor invasion and metastasis].
abstract: The aim of the study was to investigate the serum adipokine levels and expression of adipokine receptors (AdipoR1, AdipoR2) in patients with endometrial and colon cancer in relation with the main clinical morphological parameters (tumor invasion, lymph node involvement). The study included 60 endometrial cancer patients with I-II Stage and 31 patients with colon cancer (T2-4N0-2M0). Serum adipokine levels, the level of soluble form of the leptin receptor (sOb-R) and AdipoR1 and AdipoR2 expression were evaluated with ELISA. In endometrial cancer serum leptin and adiponectin levels were associated not only with metabolic disorders but also with cervical invasion. In colon cancer serum leptin level was associated with lymph node involvement. The data obtained showed the potential implication of serum adipokines into tumor invasion and metastasis. In both sites intratumoral levels of AdipoR1 H AdipoR2 were not associated with the presence of metabolic syndrome. The AdipoR1 level was related with myometrial invasion. In colon cancer patients, AdipoR1 and AdipoR2 expressions were associated with lymph node involvement, and AdipoR1 expression was correlated with tumor size. The obtained results demonstrated involvement of adipose tissue hormones (leptin and adiponectin) and adiponectin receptors (AdipoR1 and AdipoR2) in tumor growth, invasion and lymphogenic metastasis.
