Improvement of the cytological diagnostic accuracy of follicular thyroid lesions by the use of the <scp>K</scp>i‐67 proliferative index in addition to cytokeratin‐19 and <scp>HBME</scp>‐1 immunomarkers: a study of 61 cases of liquid‐based FNA cytology with histological controls

Abstract

Immunocytochemistry using HBME-1, CK-19 and the Ki-67 proliferative index increased the diagnostic accuracy of FNA in the FN/SFN category of the Bethesda System, which may help to distinguish lesions in this category with a low or high risk of malignancy. Thus, clinical management would be improved.
