GCNT2 and metastatic malignant neoplasm in the lymph nodes: Studies have reported that the diagnostic accuracy for predicting lymph node metastasis via GCNT2 hypomethylation in primary tumours was 86.2% which is higher than the diagnostic accuracies of CT (59.38%) and MRI (84%) methods used to predict lymph node metastasis in CRC [26,60,115].
