WFDC2 and benign neoplasm: A recent study by Boylan and colleagues18 reports perfect classification (AUC = 1.0 and AUC = 1.0) of benign tumors and late-stage ovarian cancer and very high performances (AUC = 0.98 and AUC = 0.85) using either MUCIN-16 or WFDC2 alone, by analysis of a single cohort with proteins measured using the same PEA technology as in our study.
