A. At a specificity cut-off of 91% by the model, the 5-marker panel was able to detect 43% stage I, 64% stage II, 77% stage III, and 92% stage IV disease. The marker panel detected 74% of esophageal cancer overall, 74% of esophageal adenocarcinoma, and 78% of esophageal squamous cell carcinoma. Confidence intervals are shown. B. Overall discrimination of esophageal cancer by methylated DNA marker panel assayed from plasma: areas under the receiver operating characteristic curves for best-fit and cross-validation analyses (and 95% confidence intervals) are shown.
AUC, area under the receiver operating characteristics curve.
