Prognostic Value of Combined Detection of Preoperative Albumin-to-Fibrinogen Ratio and Neutrophil-to-Lymphocyte Ratio in Operable Esophageal Squamous Cell Carcinoma Patients without Neoadjuvant Therapy
Cancer management and research(2021)
摘要
Background: We retrospectively analyzed the prognostic value of the albumin-to-fibrinogen ratio (AFR)-neutrophil-to-lymphocyte ratio (NLR) score, comprising preoperative AFR and NLR, in esophageal squamous cell carcinoma (ESCC) patients after radical resection. Patients and Methods: Overall, 215 patients were included. The optimal cutoff value was determined using the receiver operating characteristic (ROC) curve. Based on a low AFR (<12.06) and high NLR (>= 1.78), the AFR-NLR score was classified as 2 (both hematological abnormalities present), 1 (one abnormality present), or 0 (both abnormalities absent). Kaplan-Meier curves, Cox regression, and predicted nomogram were used to evaluate the prognostic value of the score. Results: The prognostic value of the AFR-NLR score was better than that of AFR or NLR alone (P < 0.05). Multivariate analysis showed that a high AFR-NLR score was an independent predictor of poor prognosis for overall survival (P < 0.001). Additionally, in the nomogram including the AFR-NLR score, the net reclassification improvement index increased by 35.5% (P < 0.001), and the integrated discrimination improvement index increased by 9.0% (P < 0.001). The predictive accuracy of the established nomogram model was proved using Harrell's concordance index (0.811, 95% confidence interval: 0.765-0.856) and calibration curve. Notably, the decision analysis curve showed that the nomogram had a higher net benefit within most of the threshold probability range, indicating better clinical applicability. Conclusion: The AFR-NLR score is a useful predictor of the prognosis of ESCC patients after radical resection, and the nomogram established on the basis of this score has a good prognostic value.
