Boeding JRE, et al. - In this single-center observational retrospective cohort study, researchers assessed the long-term survival of patients presenting with acute obstructive colorectal cancer (CRC). Participants in the study were all CRC patients who had surgery between December 2004 and 2010. Shorter short-term overall survival was found in patients with obstructive CRC. Compared to patients without obstruction, long-term overall survival was decreased in patients presenting with acute obstructive CRC.
