The resultant AUC values were 0.96 for HE4 (95% CI 0.90-1.0) and 0.82 for CA125 (95% CI 0.70-0.94) (p < 0.01), which would make them feasible for use as tumor markers, have also investigated the usefulness of HE4 in to differentiate ovarian cancers from healthy and benign gynecologic conditions. Here, WFDC2 is linked to ovarian cancer.
