ROC curve was plotted and a cutoff value of 144.85 kPa was calculated with the highest combination of sensitivity and specificity, patients with BCR had 74.4% possibility of cancer stiffness value above 144.85 kPa (sensitivity), and patients with BCR free had a 61.7% possibility of cancer stiffness value below 144.85 kPa (specificity, p < 0.05). The gene discussed is BCR; the disease is cancer.
