The receiver operating characteristic curve analysis. The receiver operating characteristic (ROC) curve analysis was performed in order to determine the cut off value of d-dimer levels. A. Local recurrence. B. Metastasis. C. Tumor specific death. The optimal cut off value of d-dimer was determined at the point on ROC curve at which (sensitivity+specificity-1) was maximized (Youden index). For metastasis, optimal cut off value of d-dimer was 0.41 μg/ml with which sensitivity and specificity were 0.83 and 0.57, respectively. In a similar way for total survival, optimal cut off value of d-dimer was 0.80 μg/ml with which sensitivity and specificity were 0.80 and 0.75, respectively.
