Ascitic interleukin-12 is an independent prognostic factor in ovarian cancer.

PURPOSEThe clinical impact of endogenous cytokines supplied with deterministic properties in the generation of either T helper (Th)1 -type or Th2-type immune response was investigated in patients with ovarian cancer. Whereas interleukin (IL)- 12 initiates the differentiation of naive Th0 cells toward Th1 phenotype, IL-4 and IL-10 mediate the development of Th2-type immunity.PATIENTS AND METHODSCytokines were determined before treatment by means of enzyme-linked immunosorbent assay (ELISA) in ascites fluid and serum of 76 patients with ovarian cancer. Cytokine levels were compared with each other and with standard clinicopathologic parameters. A stepwise logistic regression was calculated to rule out interdependence in the associations of the various variables. Survival analyses were performed with the Kaplan-Meier method and differences in survival were examined according to Mantel and Breslow. Cox proportional hazards analysis was used to identify independent prognostic factors.RESULTSWhereas IL-10 and I...
