In this study, the USWE stiffness value was able to distinguish BCR and BCR-free sub-cohort populations as shown in the first ROC curve (Figure 3, left), and then using Youden analysis (14), cancers' stiffness cutoff value 144.85 kPa in Young's modulus was higher in our study in comparison to the number of other reports in diagnosing cancer, but this was defined with the highest combination of sensitivity and specificity, and a larger number of high-grade cancers might have influenced this cutoff value. This evidence concerns the gene BCR and cancer.
