{Abstract}: With the continuous improvement of treatment strategy, the prognostic value of international prognostic index (IPI) alone is limited for diffuse large B-cell lymphoma (DLBCL). Our study aims to explore the effect of lactate dehydrogenase (LDH)to absolute lymphocyte count (ALC) ratio (LAR) and albumin to fibrinogen ratio (AFR) on the prognosis of patients with DLBCL. The venous blood LDH, ALC, albumin and fibrinogen within 1 week before the first chemotherapy in 74 DLBCL patients were collected to calculate the LAR and AFR values. The impact of LAR and AFR on the progression-free survival (PFS) of patients with DLBCL was studied by the survival analysis. The area under the receiver operating characteristic curve (AUC) and concordance index (C-index) were used to analyze the predictive efficiency of each model for the PFS of DLBCL patients. Cox univariate analysis suggested that elevated LAR (P < .001) and decreased AFR (P < .001) were risk factors for PFS in DLBCL patients. Multivariate analysis revealed that LAR (P < .001) and AFR (P = .004) were 2 independent prognostic parameters. The AUC values of IPI, AFR + IPI, LAR + IPI and AFR + LAR + IPI to predict the PFS of DLBCL patients were 0.806 (95%CI 0.707-0.905, P < .001), 0.839 (95%CI 0.747-0.932, P < .001), 0.851 (95%CI 0.764-0.938, P < .001), and 0.869 (95%CI 0.787-0.952, P < .001), respectively. The C-index values of above 4 models were 0.802 (95%CI 0.629-0.975, P < .001), 0.842 (95% CI 0.735-0.949, P < .001), 0.846 (95%CI 0.716-0.976, P < .001), and 0.864 (95%CI 0.781-0.941, P < .001), respectively. The results suggest that both LAR and AFR are independent prognostic factors for PFS in DLBCL patients. Furthermore, their combination with IPI has better predictive efficiency for the prognosis of DLBCL patients.
