Cancer Immunotherapy Related Endocrine Adverse Effects

Cancer immunotherapy has emerged as a promising therapy for a wide variety of tumors. Immune checkpoint inhibitors including anti cytotoxic T lymphocyte antigen 4 (CTLA-4), programmed death 1 (PD-1) and programmed death ligand-1 (PD-L1) monoclonal antibodies have proven to be especially effective in various advanced cancers. However, cancer the immunotherapy disturbs the immune system and may also cause immune related side effects (IRAE) distinguished from cytotoxic chemotherapy toxicity. Among them, endocrine IRAE has been reported with a higher incidence than other organ IRAE. We focus on the most relevant and new aspects related to endocrine IRAE due to cancer immunotherapy in this review.
