Abstract
BACKGROUND: Chronic inflammation is a hallmark of colorectal mucinous adenocarcinoma (CMA). Albumin-to-fibrinogen ratio (AFR) and fibrinogen-to-pre-albumin ratio (FPR) were independent prognostic factors for many kinds of solid malignancies. However, the association between the inflammatory scores and progression of metastatic CMA remains unknown. METHODS: Peripheral blood neutrophil count and circulating fibrinogen, albumin, and pre-albumin levels were detected, and neutrophil-to-albumin ratio (NAR), neutrophil-to-pre-albumin ratio(NPAR), AFR, and FPR were calculated in 42 metastatic MCA patients. Kaplan-Meier curve, Cox regression, time-dependent receiver operating characteristic curve (tdROC) were selected to investigate the prognostic utility of them in the patients. RESULTS: Metastatic CMA patients commonly occurred in middle-younger patients (80.95%). NPAR (adjusted hazard ratio (HR)=2.405, 95% confidence interval (CI)=1.195-4.842) and FPR (plog-rank =0.007, adjusted HR=2.364, 95% CI=1.203-4.645) were significantly associated with poor progression-free survival in these patients. The prognostic prediction area under tdROC (AUROC) of FPR was significantly higher than that of NPAR(0.703 versus 0.537). Moreover, the patients with a high CA19-9-FPR score showed worse outcomes than those with the low score (plog-rank <0.001, adjusted HR=7.273, 95% CI=2.721-19.435 for the score 1 versus 0). The prediction AUROC, sensitivity, and specificity of the score were 0.892 (0.788-0.996), 76.32%, and 100.00%, respectively, and its predicted efficacy was better than that of the single biomarkers. CONCLUSION: The combined CA19-9-FPR score is an economical, simple, effective, and independent prognostic factor for metastatic MCA.
