Introduction: Inflammation and nutrition are considered as two important causes leading to the progression and poor survival of colorectal cancer (CRC). The objective of this study is to investigate the prognostic significance of preoperative albumin-to-fibrinogen ratio (AFR), fibrinogen-to-pre-albumin ratio (FPR), fibrinogen (Fib), albumin (Alb), and pre-albumin (pre-Alb) in CRC individuals.
Materials and methods: In this study, 3 years’ follow-up was carried out in 702 stage I–III resected CRC patients diagnosed between January 2008 and December 2013. The optimal cutoff points and prognostic values of AFR, FPR, Fib, Alb, pre-Alb, and a novel carcinoembryonic antigen (CEA)-carbohydrate antigen 19-9 (CA199)-FPR (CCF) score were assessed by X-tile software, Kaplan–Meier curve, and Cox regression model. We established the CRC prognostic nomogram, and its predictive efficacy was determined by Harrell’s concordance index (c-index).
Results: Our results showed that high FPR was obviously correlated with poor survival of CRC patients. The prognostic predictive efficacy of CCF score was superior to FPR, CEA, CA199, CEA-CA199 (CCI), and CEA-FPR (CFI) score. Moreover, stage II–III patients harboring high FPR or elevated CCF (score≥1) could benefit from adjuvant chemotherapy, rather than those with low FPR or CCF (score=0). Additionally, the c-index (0.728) of the nomogram containing CCF score was significantly higher than that (0.626) without it (p<0.01).
Conclusion: These findings illustrated that FPR and CCF score were promising biomarkers to predict the prognosis of CRC and to classify the stage II–III patients who could benefit from the adjuvant chemotherapy.
