Diagnostic outcomes for serum YKL-40, CEA, CYFRA21-1 or SCCA in the diagnosis of ESCC. A. ROC curves of the serum YKL-40 levels of 150 ESCC patients and 126 controls. The estimated area under the ROC curve was observed as AUC = 0.874. B. ROC curves for the diagnostic strength to identify ESCC using YKL-40, CEA, CYFRA21-1 or SCCA (CEA: AUC = 0.652; CYFRA21-1 = 0.746; SCCA = 0.789).
