Fibrin/fibrinogen Degradation Products Are Associated With Tumor Stage and Prognosis in Patients Undergoing Resection of Esophageal Cancer

Background/Aim: To investigate the significance of preoperative fibrin/fibrinogen degradation products (FDP) in patients with esophageal cancer (EC), we examined the association between the preoperative FDP level and clinicopathological features in patients with EC who underwent McKeown esophagectomy with gastric tube reconstruction without neoadjuvant therapy. Patients and Methods: Ninety patients with EC who underwent surgery between 2006 and 2014 were included in this study. We investigated the association of FDP levels with clinicopathological features and prognosis. Results: Multivariate analysis revealed increased FDP level and pathological tumor depth to be independent prognostic factors for overall survival (OS) (p=0.008 and p=0.002, respectively). In addition, FDP levels were significantly positively associated with more advanced pathological TNM stage as a continuous variable (p for trend=0.002). Conclusion: The preoperative FDP level was associated with a poor prognosis and was an independent prognostic factor for the OS of EC patients who underwent esophagectomy. Furthermore, the tumor stage-related increase in FDP indicated that a high FDP level is associated with tumor progression in patients with EC.
