Immunotherapy has recently revolutionized the world of oncology. Nivolumab an IgG4 targeting PD-1 receptor has been approved in metastatic melanoma, renal cell carcinoma, Hodgkin lymphoma and non-small cell lung cancer. It works as a checkpoint inhibitor, allowing the immune system to clear cancer, and it is this mechanism of action which explains its toxicity also named as immmune-related adverse events.
This report describes the case of a 65-year-old female with metastatic lung adenocarcinoma treated with nivolumab. After 19º cycle she presented acute severe toxicity with pneumonitis, hypophisitis and thrombocytopenia. She was successfully treated with high dose steroids and immunoglobulins.
Immune-related adverse events associated with nivolumab are usually nonspecific, with lots of differential diagnosis. They often resolve with prompt management, however, they may get severe if treatment is not retired and systemic immunosupression with corticosteroids is initiated. As shown in this case, we must be attentive throughout the treatment and even after the end of the treatment, since not all cases occur according to what is described in the literature.
