Circulating levels of TNF-alpha and its soluble receptors in the plasma of patients with epithelial ovarian cancer.
The significance of circulating levels of TNF-alpha and its soluble receptors (sTNF-Rs) in the plasma of patients with epithelial ovarian cancer (EOC) has not been fully elucidated. The present study was to investigate the relationship of pretreatment plasma levels of TNF-alpha, sTNFR-1 and sTNFR-2 with outcome in 126 patients with EOC. Concentrations of TNF-alpha and sTNF-Rs were determined by enzyme-linked immunosorbent assay (ELISA). Median TNF-alpha and sTNF-Rs levels were significantly higher in EOC patients than in healthy controls. High plasma levels of TNF-alpha and sTNF-Rs were correlated with tumor stage and with reduced mean survival time (MST). The results of the present study suggested that preoperative plasma TNF-alpha and sTNF-Rs levels in EOC patients correlated with the highest risk of cancer progression. Thus, the clinical value of an activated TNF system in EOC needs to be further investigated.
