The pretreatment serum levels of the soluble receptors for tumor necrosis factor (p55 and p75 sTNFr) were retrospectively measured in 54 patients with cervical cancer and in 55 patients with benign uterine disease as controls. Serum mean (+/- standard deviation) concentrations of both p55 and p75 sTNFr were higher in patients with cervical cancer than in controls (2.6+/-1.3 vs 1.9+/-0.7 ng/ml, p<0.0001, and, respectively, 7.8+/-4.3 vs 5.9+/-3.0 ng/ml, p=0.009). Both receptor levels were significantly higher in patients with stage IIb-IV than in those with stage I-IIa cervical cancer or with cervical intraepithelial neoplasia (CIN) 3. Among the 31 patients with stage I-IIa disease who underwent initial surgery, the preoperative serum p55 and p75 sTNFr values correlated neither with the common prognostic variables nor with the clinical outcome. In conclusion, serum p55 and p75 sTNFr levels are significantly elevated in patients with cervical cancer. However, the serum measurement of these soluble receptors seems to be of limited clinical value for the management of patients with this malignancy.
