This study evaluated the differences in the risk for non-intestinal cancer between patients with intestinal cancer originating from different carcinogenetic statuses. Who can participate? Adult patients with histologically confirmed colorectal cancer What does this study involve? This is a retrospective cohort study describing the association between intestinal and not intestinal cancer among patients with different carcinogenetic backgrounds.
