- Abstract
Extracellular matrix degradation is required for invasion and metastasis formation in colorectal carcinoma (CRC), therefore, we have examined matrix metalloproteinases MMP-9 expression in tumors from patients with CRC. The study comprises of 360 patients who underwent bowel resection for stage II, III, IV tumors. Paraffin-embedded CRC tissue samples were used for immunohistochemical staining. Negative MMP-9 expression levels correlated with longer survival time as evaluated by disease-free survival and disease-specific survival (p =.023, p =.006). In multivariate survival (Cox) analysis, MMP9 was a significant independent predictor of DFS (p =.014), but not of DSS, which was independently predicted by disease recurrence, stage and localization. The detection of MMP-9 expression may be valuable in finding patients who are at high risk of developing disease recurrence.
