Cysteine proteases (cathepsin B and L), the serine protease urokinase-type plasminogen activator and its inhibitor type-1 play an important part in cancer invasion and metastasis. The authors determined the protease concentrations in gastric cancer tissues, using the ELISA method, in patients with gastric cancer. They evaluated the prognostic role of proteases and the relationship that these proteases may have with other histomorphological prognostic parameters such as tumor staging, grading, histotype, Borrmann classification. The Cox survival analysis showed that cathepsin B (p = 0.002), urokinase-type plasminogen activator (p = 0.0001) and the inhibitor type-1 (p = 0.0004) significantly correlated with poor prognosis. The tumor staging, grading, Borrmann classification correlated also significantly with survival time. Urokinase-type plasminogen activator was selected as the single independent variable in the Cox model (p = 0.0001).
