From: Detection of serum MMP-7 and MMP-9 in cholangiocarcinoma patients: evaluation of diagnostic accuracy
Serum levels of CEA, CA19-9, MMP-7 and MMP-9 in cholangiocarcinoma and control (benign biliary tract disease) patients. Box plots comparing levels of CEA, CA19-9, MMP-7 and MMP-9 are demonstrated. Levels of MMP-7 and MMP-9 are presented as ng/ml, while CEA and CA19-9 are presented with the log data to accommodate the wide range. *; Only the value for MMP-7 between the two groups is significantly different (Student's t-test; p < 0.001).
