BACKGROUND/AIM: Estimation of physiological ability and surgical stress (E-PASS) is reported to be useful as a predictor of postoperative complications and poor long-term survival after colorectal cancer. The total risk points (TRP) system is a simplified scoring system of E-PASS, and this study evaluated the utility of TRP in colorectal cancer resection in older patients. PATIENTS AND METHODS: The clinicopathological data of 237 patients who underwent curative resection for colorectal cancer from 2015 to 2020 were analyzed retrospectively. The data were compared between a high TRP group (≥1,000, n=38) and a low TRP group (<1,000, n=199). We also conducted an analysis to determine risk factors of postoperative complications and poor long-term survival. RESULTS: TRP showed statistically significant correlations with the comprehensive risk score (CRS) of E-PASS (R=0.999, p<0.001). The high TRP group experienced postoperative complications (Clavien-Dindo grade ≥2) more frequently (42.1% vs. 11.1%, p<0.001). Multivariate analysis showed that high TRP [odds ratio (OR)=5.214; 95% confidence interval (95%CI)=2.338-11.629; p<0.001] and age ≥80 (OR=2.760; 95%CI=1.308-5.826; p=0.008) were independent predictors of postoperative complications. Overall survival (OS) was poor in the high TRP group (5-year OS, 61.2% vs. 82.6%, p<0.001) compared with the low TRP group, and in the low prognostic nutritional index (<45) group (5-year OS, 70.9% vs. 86.3%, p=0.013) compared with the high prognostic nutritional index (≥45) group. Multivariate analysis showed that high TRP [hazard ratio (HR)=3.202; 95%CI=1.324-7,745; p=0.010] was an independent prognostic factor for poor OS. CONCLUSION: Patients aged ≥80 years should be closely monitored regarding postoperative complications. Reducing TRP to less than 1,000 is important to reduce postoperative complications and improve OS. Copyright 2022, International Institute of Anticancer Research.
