Abstract

Objective Early ovarian cancer detection is still very difficult and patients are mostly in advanced stages, with obvious influence on poor prognosis. Method Fifty-one ovarian cancer patients and 16 healthy controls had the serum concentrations of TNFα receptor p55, p75 and CA-125 measured prospectively and preoperatively. Result Mean concentrations of TNFα receptor p55, p75 and CA-125 in patients with ovarian cancer were higher than in controls. The ratios of p55 and p75 receptor in ovarian cancer and controls were 0.73±0.38 and 0.55±0.06 respectively. The areas under ROC curve in detecting malignancy (all FIGO stages) were 0.73, 0.65, 0.88 and 0.85 for p55, p75, p55/p75 ratio and CA-125 respectively. The areas under ROC curve in detecting stage I of ovarian cancer were 0.52, 0.60, 0.84 and 0.66 for p55, p75, p55/p75 ratio and CA-125 respectively. Conclusion Serum TNFα p55/p75 ratio showed promising value in ovarian cancer detection.
