Abstract:
Purpose:This study was to investigate the prognostic significance of the preoperative fibrinogen and systemic inflammation response index (F-SIRI) in a Chinese cohort of resectable gastric cancer.
Materials and Methods:Baseline characteristics, preoperative fibrinogen levels and peripheral neutrophil, monocyte, and lymphocyte counts were retrospectively reviewed in 240 patients who underwent radical gastrectomy. The optimal cut-off values for fibrinogen and SIRI were defined as 4.0 g/L and 1.2. Then patients with hyperfibrinogenemia (≥4.0 g/L) and high SIRI (≥1.2) were assigned with an F-SIRI of 2 (both of these hematological abnormalities), 1 (one of these abnormalities), and 0 (neither abnormality), respectively. The prognostic value was examined by univariate and multivariate survival analysis.
Results:Preoperative F-SIRI was significantly correlated with tumor size, fibrinogen level, and adjuvant chemotherapy. Whereas there was no significant difference in age, gender, tumor location or other characteristics between groups. In addition, high preoperative F-SIRI was significantly associated with worse disease-free survival (DFS) (hazard ratio [HR], 2.299; 95% confidence interval [CI], 1.482–3.566; P<0.001) and overall survival (OS) (HR, 2.461; 95% CI, 1.584–3.824; P<0.001) by univariate survival analysis. Moreover, it remained an independent predictor for impaired DFS (HR, 2.023; 95% CI, 1.273–3.215; P=0.003) and OS (HR, 2.341; 95% CI, 1.480–3.705; P<0.001) in multivariate Cox regression analysis.
Conclusions:Preoperative F-SIRI could serve as a significantly prognostic marker for long-term survival in Chinese patients who underwent radical gastrectomy.
