Cumulative Score Based on Preoperative Fibrinogen and Pre-albumin Could Predict Long-term Survival for Patients with Resectable Gastric Cancer

Abstract

Background: To investigate the prognostic significance of the cumulative score based on preoperative fibrinogen and pre-albumin (FP score) in patients with gastric cancer after radical gastrectomy. Methods: Baseline characteristics, preoperative fibrinogen and pre-albumin levels were retrospectively reviewed in patients who underwent radical gastrectomy. The optimal cut-off values for fibrinogen and pre-albumin were defined as 4.0 g/L and 230.0 mg/L, respectively. Patients with elevated fibrinogen (≥ 4.0 g/L) and decreased pre-albumin (< 230.0 mg/L) levels were allocated an FP score of 2, those with only one of these two abnormalities were assigned a score of 1, and those with neither of the two abnormalities were allocated a score of 0. The prognostic value was examined by univariate and multivariate regression analyses. Results: The preoperative FP score was significantly correlated with age, tumor size, fibrinogen level, pre-albumin level and white blood cell count. No significant differences based on sex, tumor location, degree of differentiation, depth of invasion, lymph node status, tumor-node-metastasis (TNM) stage or adjuvant chemotherapy were identified between the groups. In addition, univariate survival analysis revealed that a high preoperative FP score was significantly associated with unfavorable disease-free survival (DFS) [hazard ratio (HR), 1.482; 95% confidence interval (CI), 1.222-1.796; P < 0.001] and overall survival (OS) (HR, 1.623; 95% CI, 1.315-2.002; P < 0.001). Moreover, after adjusting for other factors, a high preoperative FP score remained an independent predictor for impaired DFS (HR, 1.434; 95% CI, 1.177-1.747; P < 0.001) and OS (HR, 1.413; 95% CI, 1.136-1.758; P = 0.002) in multivariate Cox regression analysis. Conclusions: The preoperative FP score significantly predicts long-term survival for gastric cancer patients who have undergone radical gastrectomy.
