(A) The serum FST levels were examined by ELISA. (B) The positive ratio of serum FST levels were represented in health subjects and patients using the 95th confidence interval in the healthy subjects as the cut-off value. Cont, health subjects control; Oa, ovarian mucinous adenocarcinoma; La, lung adenocarcinoma; Tb, tuberculosis. *P<0.01, compared with health control group. (C) Receiver-operating characteristic (ROC) curve for FST for the diagnosis of lung adenocarcinoma and ovarian cancer. AUC: the area under the curve.
