1. Serum LAMC2 levels in pancreatic adenocarcinoma (PDAC) and other samples from Japan.
Serum LAMC2 levels in pancreatic adenocarcinoma (PDAC) and other samples from Japan.A, Scatter plot of serum LAMC2 and CA19.9 concentrations determined in normal (healthy) (n = 50), benign disease (n = 50), and PDAC (n = 50) serum samples obtained from Hamamatsu University School of Medicine, Japan (for more details on the samples see Table I). The PDAC samples were not stage-classified. The horizontal lines represent median concentrations and the dotted lines are cut-off values for LAMC2 (150 ng/ml) and CA19.9 (37 U/ml). p Values were calculated by Mann-Whitney U tests. B, The sensitivity of CA19.9, LAMC2, and both in the diagnosis of PDAC and the proportion of patients tested positive for LAMC2 and their corresponding CA19.9 status (positive and negative). C, Receiver operating characteristic (ROC) curves for CA19.9, LAMC2, and both for patients with PDAC versus benign samples. AUC, area under the curve. The combined assessment of CA19.9 and LAMC2 surpassed the individual diagnostic ability of either of the two markers (p = 0.035).
