MUC16 and ovarian carcinoma: When the classification accuracy of our Proseek® data was evaluated using the ROC curve, 8 of the 12 proteins in our multi-protein classifier had AUC values at or above 0.7 (CA125, CXCL13, CD40L, CD69, LAP-TGF-β1, EpCAM, TF, and EGFR) when tested individually; the levels of three of these proteins (EpCAM, TF, and EFGR) were lower in the early stage ovarian cancer serum samples relative to the healthy controls.
