The op-timal cutoff values of related parameters were estimated by receiver operating characteristic （ROC） curve analysis. The recurrence free survival （RFS） rate was evaluated using Kaplan-Meier curves. Univariate analysis and multivariate Cox regression models were used to analyze the prognostic factors of GISTs. The relationship between the FIB, D-dimer, DFR, platelet count （PLT）, and the clinicopathological features of GISTs was described by the chi-square test or nonparametric rank sum test （Mann-Whitney test）.RESULTS In ROC analysis, the optimal cutoff values of FIB, D-dimer, DFR, and PLT were 3.24 g/L, 1.24 mg/L, 0.354, and 197.5 （× 109/L）, respectively. Univariate analysis and the Kaplan-Meier survival curve showed that FIB, D-dimer, DFR, PLT,National Institutes of Health （NIH） risk category, tumor size, tumor location, and mitotic index were signifcantly relevant to the 3-year and 5-year survival rate of patients （ P 〈 0.05）. Cox multivariate regression analysis illustrated that FIB （RR： 0.108, 95%CI： 0.031-0.373）, DFR （RR： 0.319, 95%CI： 0.131-0.777）, and NIH risk category （ RR： 0.166, 95%CI： 0.047-0.589） were independent prognostic factors of the RFS rate （ P 〈 0. 05）. Moreover, FIB, D-dimer, DFR, and PLT were correlated with the clinical features of GISTs.CONCLUSIONFIB, D-dimer, DFR, and PLT are all related to the prognosis of GISTs. Moreover, FIB and DFR may be independent risk factors for predicting the prognosis of resectable GISTs.展开更多
