Cancer immunotherapy during the COVID‐19 pandemic presents management challenges from immune‐related toxicities, requiring careful patient selection
The coronavirus disease 2019 (COVID‐19) pandemic has led to fundamental re‐evaluation of the benefits versus risks of treatment in oncology. Immunotherapy has had an expanding presence in oncology, becoming a primary systemic treatment option in diseases such as melanoma, lung, urothelial, renal, and head and neck cancers. Immune checkpoint inhibitor (ICI) therapy, namely anti‐programmed cell death protein 1 (anti‐PD‐1), anti‐programmed cell death ligand 1 (anti‐PD‐L1) and anti‐cytotoxic T‐lymphocyte‐associated protein 4 (anti‐CTLA‐4) antibodies, halt the negative regulatory checks of T lymphocytes, thus activating the immune response against tumours. Patients with cancer receiving these treatments are faced with a unique set of treatment‐related toxicities driven by an autoimmune mechanism.
