A Novel Scoring System Based on Fibrinogen and the Neutrophil-Lymphocyte Ratio as a Predictor of Chemotherapy Response and Prognosis in Patients with Advanced Gastric Cancer

Objective: We assessed the clinical applicability of the F-NLR score, which is based on fibrinogen (F) and the neutrophil-lymphocyte ratio (NLR), and the Glasgow Prognostic Score (GPS) to predict the therapeutic effects of chemotherapy or chemoradiotherapy on advanced gastric cancer and the prognoses of patients. Methods: Sixty-eight patients with advanced gastric cancer treated with first-line chemotherapy or chemoradiotherapy were classified into two groups based on tumor response. Furthermore, we categorized patients according to cutoff F-NLR scores of 2 [hyperfibrino-genemia (>400 mg/dl) and high NLR (>3.0)], 1 [one of these hematological abnormalities], and 0 [neither hyperfibrino-genemia nor high NLR]. Results: A total of 27 patients had progressive disease (PD) and 41 did not. The F-NLR scores were significantly higher in the PD than in the non-PD group (p = 0.003). Survival was significantly shorter for patients with high F-NLR scores and GPS (p = 0.0071 and p = 0.0065, respectively). Multivariate analysis selected the F-NLR score as an independent prognostic factor (p = 0.017). Conclusion: A novel grading system based on F-NLR scores, as well as the GPS, appears to have value as a clinical predictor of the therapeutic response of advanced gastric cancer to chemotherapy or chemoradiotherapy and the prognoses of patients.
