Prognostic Significance of plasma albumin to fibrinogen ratio Associated Nomograms in Patients with breast invasive ductal carcinoma
Abstract Background : In the context of breast invasive ductal carcinoma, this research aims to retrospectively evaluate by preoperative plasma albumin to fibrinogen ratio (AFR) and forecast oncological outcome and recurrence. Methods : This reflective study included 230 patients who had surgical procedures at the Fourth Hospital of Hebei Medical University between January 2009 and April 2012 for the treatment of their non-metastatic breast invasive ductal carcinoma. We utilized an optimal value of preoperative plasma fibrinogen and albumin for the patient classification. Additionally, we used the Kaplan-Meier method to extensively evaluate progression-free and cancer-specific survival outcomes. The analysis of the linkages between the albumin to fibrinogen ratio and clinical outcomes was executed through the univariate and multivariate analyses. To construct nomograms and evaluate the survival outcomes, we used a variety of risk factors. We also verified the predictive accuracy through the Harrell's concordance index (C-index). Results : The association of plasma AFR with diminished disease-free survival (DFS) and overall survival (OS) is statistically significant. An independent prognostic indicator is the plasma AFR, as reported by the multivariate analysis, for DFS (HR =1.346; 95% CI:1.107-1.636; p = 0.03) and overall survival (OS) (HR = 1.485; 95% CI: 1.106-1.993; p = 0.008). Two prediction model of OS and DFS based on the AFR was developed. Conclusions : For patients with breast invasive ductal carcinoma, an independent prognostic factor for the outcomes of oncology patients is the elevated preoperative plasma AFR. For DFS and OS, the constructed nomogram demonstrated highly significant predictive accuracy.
