ABSTRACT
Pancreatic cancer and chronic pancreatitis are still significant diagnostic and clinical problems. A tumor marker that would eliminate the imperfection of preoperative serum carbohydrate antigen 19-9 (CA19-9) concentration is still being sought. This study aimed to conduct a comparative analysis of the concentrations in serum and peritoneal cavity of matrix metalloproteinases metalloproteinase-2 (MMP-2), metalloproteinase-9 (MMP-9), CA19-9, and carcinoembryonic antigen (CEA) in patients with pancreatic cancer (PC), chronic pancreatitis (CP) and a control group (CG). The study was performed in a group of 90 patients. Group 1 consisted of 30 patients with PC, group 2 consisted of 30 patients with CP. There was no case of pancreatic cancer in the CP group. Group 3 (CG) consisted of 30 individuals, who were recruited among patients operated for non-inflammatory cholelithiasis. The serum samples and intraperitoneal fluid, when present or samples of peritoneal lavage were taken from patients and the concentration of MMP-2, MMP-9, and CA19-9 were evaluated. The revealed intraperitoneal fluid concentrations of the MMP-2, MMP-9, and CA19-9 were significantly higher in both PC and CP groups in comparison to CG. There were no statistically significant differences between intraperitoneal fluid concentrations of the MMP2, MMP9, and CA19-9 in PC and CP groups. The revealed serum concentration of the MMP-2 and MMP-9 in the PC, CP, and CG were significantly higher compared to the intraperitoneal fluid. There was no significant correlation between serum and intraperitoneal fluid concentration of the MMP-2, MMP-9, and CA19-9 and the presence of cancer cells in the intraperitoneal fluid conventional cytological examination. The elevated preoperative intraperitoneal fluid concentration of MMP-2 and MMP-9 and serum concentration of CA19-9 and CEA showed significant sensitivity and specificity in PC prediction. The preoperative serum concentrations of MMP-2 and MMP-9, serum, and intraperitoneal fluid concentrations of CA19-9 and CEA have been shown to have a statistically significant effect on predicting cancer progression and the presence of distant metastases. Presented findings suggest the usefulness of MMP-2 and MMP-9 as a potential predictor of PC and marker of dissemination but its usefulness in the differential diagnosis between PC and CP is limited, however more studies on a large population are needed to support our result. To our knowledge, this was the first study evaluating not only MMP-2 and MMP-9 concentrations in serum but also the concentration of these metalloproteinases in peritoneal fluid in patients with PC and CP.
