Key result
P-POSSUM and CR-POSSUM accurately predicted 30-day mortality in elderly colorectal cancer patients (expected 11.21% and 13.08% vs observed 10.3%, P=NS), but P-POSSUM overestimated morbidity.

May support mortality risk assessment in elderly colorectal cancer surgery; leaves open morbidity model refinement and prospective validation.
Cohort (n=177)
Do P-POSSUM and CR-POSSUM accurately predict 30-day mortality and morbidity in elderly patients undergoing colorectal cancer surgery?
Absolute Event Rate: 11.21% vs 10.3%
p-value: p=NS
P-POSSUM and CR-POSSUM accurately predict 30-day mortality in elderly colorectal cancer patients, but P-POSSUM significantly overestimates morbidity.
Ugolini et al. (2008) conducted a cohort in Colorectal cancer (n=177). P-POSSUM and CR-POSSUM scoring systems vs. Observed outcomes was evaluated on 30-day mortality (p=NS). P-POSSUM and CR-POSSUM accurately predicted 30-day mortality in elderly colorectal cancer patients (expected 11.21% and 13.08% vs observed 10.3%, P=NS), but P-POSSUM overestimated morbidity.
