- Background and Objectives: Degradation of extracellular matrix is important for tumour growth and invasion, which in part is regulated by the plasminogen activation system. The aim of the study was to evaluate the protein expression of urokinase plasminogen activator (uPA) and plasminogen-activating inhibitor-1 (PAI-1) in plasma, tumour-free mucosa and tumour tissue regarding their prognostic value in colon and rectal cancer. Methods: Patients (n = 221) undergoing surgery for colorectal cancer were prospectively included. Samples were assayed by ELISA technique. Results: PAI-1 in tumour tissue (p = 0.006), plasma (<0.0001) and uPA in tumour-free mucosa (p = 0.006) were associated with survival in rectal cancer in univariate analysis. An uPA expression level below 1.1 ng/mg (log rank test, p < 0.0001) in tumour-free mucosa was associated with poor survival in rectal cancer. This was true also for patients without disseminated disease (M(0), p = 0.02). PAI-1 in plasma correlated with metastatic disease (p < 0.0001). uPA and PAI-1 were not associated with survival in either tumour tissue, mucosa or plasma in patients with colon cancer. Conclusions: uPA and PAI-1 have a differential prognostic impact in colon and rectal cancer. Preoperative mucosal uPA and plasma PAI-1 protein expression could possibly be used as prognostic factors in rectal cancer.
