Key result
A prediction model incorporating age, ASA grade, operative urgency, cancer excision, and metastatic disease offered adequate discrimination (AUC 0.732) for 30-day mortality (overall 15.6%).
Observational (n=2,533)
Yes
A developed multilevel logistic regression model can accurately estimate 30-day mortality in patients older than 80 years undergoing surgery for colorectal cancer.

May aid preoperative counseling in octogenarians with colorectal cancer; leaves open external validation before clinical use.
Heriot et al. (2006) conducted an observational in colorectal cancer (n=2,533). Risk factors for postoperative mortality (age, ASA grade, operative urgency, cancer excision, metastatic disease) was evaluated on 30-day operative mortality. A prediction model incorporating age, ASA grade, operative urgency, cancer excision, and metastatic disease offered adequate discrimination (AUC 0.732) for 30-day mortality (overall 15.6%).
