Prognostic Impact of Pretreatment Plasma Fibrinogen in Patients with Locally Advanced Oral and Oropharyngeal Cancer

Abstract: BackgroundWe aimed to determine the prognostic significance of pretreatment plasma fibrinigen in patients with oral and oropharyngeal squamous cell carcinoma (OOSCC).MethodsA cohort of 183 patients with locally advanced OOSCC receiving preoperative chemoradiotherapy was retrospectively examined. Using ROC curve analysis, a pretreatment plasma fibrinogen cutoff value of 447mg/dL was determined. The primary endpoints were overall survival and recurrence-free survival. A secondary endpoint was to determine whethe… Show more

“…Liu Z and Liu P [6, 10] used 4.0 g/L as the cut-off value for FIB and 300*10^9/L for PLT, and both were significantly correlated with overall survival (P < 0.001 and P = 0.010, respectively). In a study by Holzinger et al [17], 447 mg/dL was set as the cut-off value for FIB in patients with oral and oropharyngeal cancer, and elevated FIB was associated with poor overall survival (P = 0.005) and recurrence-free survival (P = 0.008). In our study, the cut-off values of FIB and PLT were set as the mean value (3.33 g/L and 259.5*10^9/L, respectively).…”

“…[ 9 , 24 ] The mechanism underlying this association may be the binding of fibrinogen to members of the transforming growth factor-B, vascular endothelial growth factor, platelet-derived growth factor, and fibroblast growth factor gene families, thereby leading to the inhibition of apoptosis, angiogenesis, and metastasis and promotion of tumor cell proliferation. [ 8 , 25 ] Platelet-fibrin microthrombi appear to act as a physical barrier, preventing contact between natural killer cells and tumor cells. [ 26 ] Moreover, fibrinogen acts as a bridging factor between tumor and host cells and enhances the endothelial adhesion of tumor cell emboli in the vasculature of target organs.…”

“…An increasing number of studies have focused on the association between hypercoagulation and malignancy progression. Recent studies have provided strong evidence that plasma fibrinogen is associated with tumor progression and poor prognosis in lung cancer, [ 4 ] breast cancer, [ 5 ] gastric cancer, [ 6 ] ovarian cancer, [ 7 ] oral and oropharyngeal cancer, [ 8 ] biliary tract cancer, [ 9 ] and penile cancer [ 10 ] patients. Fibrinogen is a 340-kDa glycoprotein that is synthesized in the liver and converted into fibrin by active thrombin.…”

“…To evaluate the relationship between baseline clinico-pathological and laboratory parameters and tumor response after nRCT, logistic regression analysis was applied. Receiver operating characteristic (ROC) curve analysis was performed to estimate the optimal CRP cutoff value as reported previously [ 28 , 29 ]. The optimal cutoff value was determined as the point on the ROC curve that maximizes the Youden Index.…”
