Circulating fibrinogen to pre-albumin ratio is a promising biomarker for diagnosis of colorectal cancer.


ABSTRACT:

Background

Inflammation and nutrition are closely associated with initiation and progression of colorectal cancer (CRC). This study aimed to investigate the diagnostic value of the FAR (FAR = 100*Fibrinogen/Albumin) and FPR (FPR = Fibrinogen/pre-Albumin) in CRC.

Methods

Neutrophil-to-lymphocyte ratio (NLR), FPR, and FAR were calculated in 455 newly diagnosed CRC patients, 455 healthy individuals, and 455 benign controls with colorectal polyp. The diagnostic value of biomarker for CRC was evaluated by receiver operating characteristic curve (ROC). Logistic regression analysis was adopted to assess the risk factors for telling CRC apart from benign disease. Moreover, the combined biomarkers were used for discriminating between CRC and benign disease.

Results

Neutrophil-to-lymphocyte ratio, FAR, and FPR were significantly higher in CRC patients compared with the benign or healthy controls (P < 0.05). ROC analysis showed that the diagnostic efficacy of FAR and FPR were better than NLR for CRC. Besides, FPR, NLR, carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 (CA199) were markedly associated with differentiation of benign disease and CRC in the logistic regression analysis. And the combination of FPR, CEA, and CA199 had the maximum area under the ROC curve (AUC) in separating CRC from benign disease (AUC = 0.845, Sensitivity = 67.9%, Specificity = 85.3%, Positive Predictive Value = 83.5%, Negative Predictive Value = 70.9%).

Conclusions

Fibrinogen/pre-Albumin could be a useful CRC diagnostic biomarker, and the combination of FPR, CEA, and CA199 could significantly improve the diagnostic efficacy in discriminating CRC from the benign colorectal disease.
