BACKGROUND

Little is known regarding recent trends in the rate of nonelective colon cancer resection in the United States and its impact on both short-term and long-term outcomes.

METHODS

The New York State Cancer Registry and Statewide Planning & Research Cooperative System identified stage I-III colon cancer resections from 2004-2011. Propensity-matched analyses assessed differences in short-term adverse outcomes and 5-year disease-specific and overall survival between elective and nonelective colon cancer operations. Further analyses assessed the association among patient, surgeon, and hospital-level factors and outcomes within the nonelective operation group.

RESULTS

Among 26,420 patients, 26.5% underwent nonelective operations. There was no significant change in the rate of nonelective resection from 2004-2011 (P = .25). Nonelective operations were independently associated with greater odds of 30-day mortality (odds ratio [OR] = 3.42, 95% confidence interval [CI] = 2.87-4.06), stoma creation (OR = 4.49, 95% CI = 3.95-5.09), intensive care unit admission (OR = 1.68, 95% CI = 1.53-1.84), complications (OR = 2.34, 95% CI = 2.18-2.52), and discharge to another health care facility (OR = 2.46, 95% CI = 2.26-2.68), longer duration of stay (incidence rate ratio = 1.79, 95% CI = 1.76-1.83), and worse disease-specific (hazard ratio = 1.74, 95% CI = 1.61-1.88) and overall survival (hazard ratio = 1.64, 95% CI = 1.55-1.75). Other than an association among high-volume surgeons, adequate lymph node yield, and receipt of adjuvant chemotherapy and lower mortality, no other potentially modifiable factors were associated with survival after nonelective operations.

CONCLUSION

Nonelective colon cancer resection remains a concerning public health issue with >25% of cases being performed on a nonelective basis and an independent association with poor short-term and long-term survival compared with elective operations. Given that few potentially modifiable factors appear to have an impact on survival after nonelective operations, these findings highlight the importance of adherence to colon cancer screening guidelines to limit the number of nonelective colon cancer resections.
