Abstract: Postoperative complications after colorectal cancer surgery have been associated with poor long-term prognosis. The aim of the present study was to investigate the prognostic impact of postoperative complications after colorectal cancer surgery assessed by the Comprehensive Complication Index (CCI®) and designing a new prognostic score based on this index. Methods: This observational longitudinal study included a series of 604 patients who underwent colorectal surgery for cancer. Demographic data, comorbidity measured by Charlson Index, tumor characteristics, surgical data and postoperative complications were recorded as predictors. Univariate and multivariate analysis were performed and long-term survival was the output variable. Based on Hazard Ratios obtained on multivariate analysis, a new score, S-CRC-PC, was created for predicting long-term survival. Results: Two-hundred and twelve (35.1%) patients developed some postoperative complication. The mean CCI was 11.6 (±19.19). Mild complications (CCI <26.2) were detected in 95 (15.7%) patients. Moderate complications (CCI 26.2–42.2) were detected in 64 (10.6%) patients. Severe complications (CCI >42.3) were detected in 53 patients (8.8%) patients. Mortality rate was 1.7%. In multivariate analysis, age (p < 0.001), Charlson score (p = 0.014), CCI (p < 0.001), and TNM stage (p < 0.001) were statistically significantly in relation to long-term survival rate. S-CRC-PC score was statistically associated with survival rate (HR: 1.34–95% CI: 1.27–1.41). Patients with S-CRC-PC values from 0 to 8 points (low risk), 8.1–16 points (medium risk), and scores above 16 points (high risk) had a cumulative survival rate at five-years of 98%, 83%, and 31% respectively. Conclusions: Postoperative complications after colorectal cancer surgery assessed by CCI are an independent prognostic factor of survival rate. The S-CRC-PC score may be helpful in predicting long-term cancer outcomes.
