Key clinical point: Most rheumatic immune-related adverse events resulting from cancer therapy were not severe, could be verified by C-reactive protein and imaging, and were readily treatable.

Major finding: The large majority of patients had an elevated C-reactive protein level (76%) and pathology on joint ultrasound (96%); most cases (80%) were manageable with prednisone either alone or combined with NSAIDs.

Study details: A multicenter registry cohort study of 69 patients having rheumatic symptoms as a result of immune checkpoint inhibitor therapy or other cancer therapies.
