According to the ROC curve, cut-off points determined for other analysed parameters were as follows: for Ki-67 expression, the cut-off value was 15% with 55.9% specificity and 81.8% sensitivity (AUC = 0.705, p = 0.0073); the cut-off value for pre-treatment AOPP concentration was 9.37 μM with 78% specificity and 72.7% sensitivity (AUC = 0.773, p = 0.0005); for the tumour diameter, the cut-off point was 1.8 cm with 62.7% specificity and 81.8% sensitivity (AUC = 0.769, p = 0.0001). The gene discussed is MKI67; the disease is neoplasm.
