Current preoperative risk stratification modalities for pancreatic ductal adenocarcinoma (PDA) patients are inadequate. Elevated serum matrix metalloproteinase 7 (MMP7) is associated with metastatic PDA. We evaluated preoperative MMP7 level as a prognostic marker in patients with resectable PDA. From a prospectively maintained database, we identified PDA patients who underwent operation with curative intent from 2004 to 2008 and had serum collected preoperatively. MMP7 was measured by enzyme-linked immunosorbent assay. Patients were defined as having advanced disease if they were found to be unresectable at the time of operation or had nodal involvement on final pathology. Preoperative serum samples were available for 134 patients. Using a cutoff of 13.5 ng/mL, MMP7 was highly predictive for advanced disease. For patients who underwent R0 resection, MMP7 > 13.5 ng/mL was strongly associated with N1 status, T3/T4 stage, moderate/poor differentiation, and perineural invasion. The median recurrence-free survival was 5.0 months in patients with MMP7 > 13.5 ng/mL versus 9.9 months for patients with lower values (P = 0.004). Very elevated serum MMP7 was highly predictive of unresectable disease and nodal involvement despite favorable preoperative cross-sectional imaging. MMP7 should be further evaluated as a biomarker to risk-stratify PDA patients prior to operation.
