This study is aimed at developing and validating a novel scoring system, based on oxidative stress indexes, for prognostic prediction in CRC patients. A retrospective analysis of 1422 CRC patients who underwent surgical resection between January 2013 and December 2017 was performed. These patients were randomly assigned to the training set (<jats:italic>n<\/jats:italic> = 1022) or the validation set (<jats:italic>n<\/jats:italic> = 400). Cox regression model was used to analyze the laboratory parameters. The CRC\u2010Integrated Oxidative Stress Score (CIOSS) was developed from albumin (ALB), direct bilirubin (DBIL), and blood urea nitrogen (BUN), which were significantly associated with survival in CRC patients. Furthermore, a survival nomogram was generated by combining the CIOSS with other beneficial clinical characteristics. The CIOSS generated was as follows: 0.074 \u00d7 albumin (g\/L), \u22120.094 \u00d7 bilirubin (<jats:italic>\u03bc<\/jats:italic>mol\/L), and \u20100.099 \u00d7 blood\u2009urea\u2009nitrogen (mmol\/L), based on the multivariable Cox regression analysis. Using 50% (0.1025) and 85% (0.481) of CIOSS as cutoff values, three prognostically distinct groups were formed. Patients with high CIOSS experienced worse overall survival (OS) (hazard\u2009ratio\u2009[HR] = 4.33; 95% confidence interval [CI], 2.80\u20106.68; <jats:italic>P<\/jats:italic> &lt; 0.001) and worse disease\u2010free survival (DFS) (HR = 3.02; 95% CI, 1.96\u20104.64; <jats:italic>P<\/jats:italic> &lt; 0.001) compared to those with low CIOSS. This predictive nomogram had good calibration and discrimination. ROC analyses showed that the CIOSS possessed excellent performance (AUC = 0.818) in predicting DFS. The AUC of the OS nomogram based on CIOSS, TNM stage, T stage, and chemotherapy was 0.812, while that of the DFS nomogram based on CIOSS, T stage, and TNM stage was 0.855. Decision curve analysis showed that these two prediction models were clinically useful. CIOSS is a CRC\u2010specific prognostic index based on the combination of available oxidative stress indexes. High CIOSS is a powerful indicator of poor prognosis. The CIOSS also showed better predictive performance compared to TNM stage in CRC patients.<\/jats:p>","DOI":"10.1155\/2021\/6693707","type":"journal-article","created":{"date-parts":[[2021,1,9]],"date-time":"2021-01-09T15:50:57Z","timestamp":1610207457000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["An
