By studying the impact of intestinal stents on the CC pathology and Matrix Metalloproteinase-2 (MMP-2), MMP-9, and 8-hydroxy-2′-deoxyguanosine (8-OHdG) expression levels, the impact of intestinal stents on long-term tumor prognosis will be explained from a molecular perspective. This evidence concerns the gene MMP2 and neoplasm.
