Combination of preoperative fibrinogen and neutrophil to lymphocyte ratio is a predictive prognostic factor in ESCC and AEG systematic review

Abstract

Abstract Objective: Cancer-associated systemic inflammation response and hyperfibrinogenemia play crucial roles in cancer progression and prognosis. In the present study, we assessed the clinical value of the preoperative fibrinogen and the neutrophil to lymphocyte ratio (NLR) in patients with esophageal squamous cell carcinoma (ESCC) and adenocarcinoma of the esophagogastric junction (AEG). Methods: Three hundred and fifty-six patients who underwent curative surgery were retrospectively analyzed. Univariate and Multivariate Cox analyses were performed to evaluate the prognostic indicators for overall survival (OS). The optimization cut-off values for fibrinogen and the NLR were 3.09 g/l and 1.89, respectively. The fibrinogen and the NLR (F-NLR) index was 2 for patients with high fibrinogen (≥3.09 g/l) and elevated NLR (≥1.89), whereas those with one or neither were indexed as 1 or 0, respectively. Results: The F-NLR score was significantly associated with tumor size (P<0.001), and pathological stage (P=0.010). The 5-year OS rates in F-NLR groups 0, 1 and 2 were 69.1, 42.6, and 31.9%, respectively (P<0.001). Multivariate analysis showed that the tumor size (P<0.001), pathological stage (P<0.001), and F-NLR (P<0.001) were independent prognostic factors for OS. Conclusions: The preoperative F-NLR score is an independent prognosis indicator for patients with ESCC and AEG.
