Clinical Significance of Thyroid Autoantibodies in Differential Diagnosis and Predicting the Course of Programmed Cell Death Protein-1 Inhibitor-Induced Thyroid Dysfunction

Thyroid immune-related thyrotoxicosis is one of the most common adverse effects in patients treated with programmed cell death protein-1 (PD-1) inhibitors. We investigated the significance of levels of serum anti-thyroglobulin antibodies (TgAbs), anti-thyroid peroxidase antibodies (TPOAbs), and TSH receptor antibodies (TRAbs) in the identification of anti-PD-1-induced thyroid thyrotoxicosis.
