Key result
Emergency colorectal cancer surgery is linked to ~26% lower absolute 5-year survival versus elective surgery.
Why the study?
Patients undergoing emergency operations for colorectal cancer have poorer long-term survival compared with elective patients, and the role of tumor pathology in these differences was unclear.
Does emergency presentation for colorectal cancer surgery result in worse long-term survival compared to elective presentation?

Emergency colorectal cancer resection associates with poorer survival; leaves open whether tumor pathology fully accounts for the gap.

Does emergency presentation for colorectal cancer surgery result in worse long-term survival compared to elective presentation?
Absolute Event Rate: 39.2% vs 64.7%
p-value: p=<0.0001
Patients undergoing emergency surgery for colorectal cancer have significantly worse long-term survival than those undergoing elective surgery, which is largely attributable to more advanced tumor pathology at presentation.
Wong et al. (2007) conducted a cohort in Colorectal cancer (n=1,823). Emergency operation vs. Elective operation was evaluated on Five-year all-cause survival rate (excluding 30-day mortality) (p=<0.0001). Emergency operations for colorectal cancer were associated with a significantly lower five-year all-cause survival rate compared to elective operations (39.2% vs. 64.7%, P<0.0001).
