Hyperfibrinogenemia is associated with poor prognosis in various cancers; however, its clinical relevance in gastric cancer has not been well analyzed. We conducted this study to assess the clinicopathological significance and prognostic value of hyperfibrinogenemia in patients with gastric cancer.
Plasma fibrinogen levels were measured preoperatively in 315 patients undergoing surgery for gastric cancer. We then evaluated the clinicopathological significance of hyperfibrinogenemia and its relationship with several biomarkers, including white blood cell (WBC), C-reactive protein (CRP), platelet count, prothrombin time (PT) and activated partial thromboplastin time (APTT). Postoperative plasma levels were compared with preoperative levels. The multivariate prognostic value of hyperfibrinogenemia was calculated using the Cox proportional hazards model.
Tumor progression was significantly associated with hyperfibrinogenemia, as were the CRP level and platelet counts. Plasma fibrinogen levels decreased significantly after radical surgery. Adjusting for TNM factors, multivariate analysis indicated that hyperfibrinogenemia was an independent prognostic factor for poor survival (hazard ratio = 2.607, 95 % confidence interval = 1.180–5.761, P = 0.018).
Preoperative hyperfibrinogenemia was associated with tumor progression, inflammatory mediators, and poor overall survival in patients with gastric cancer.
