Introduction: In the thyroid gland, humoral immunity manifests with thyroid peroxidase (TPO) antibodies. In our studies, when TPO concentrations increased, thyroid cancers of follicular origin (TCFO) tended to develop less frequently.1 Other studies, though, reported an opposite trend in less aggressive cancers. The present work was designed to characterize the differential role of TPO antibodies in aggressive forms of TCFO (AGG) as compared to non-aggressive (NAG) ...
