An Italian retrospective study of 411 idiopathic inflammatory myopathies (IIM) patients applied IMACS criteria to assess the risk of cancer and found significantly more cancers in those at high risk.

Idiopathic inflammatory myopathies (IIM) are a heterogenous group of autoimmune conditions with substantial morbidity. EULAR in collaboration with the American College of Rheumatology (ACR) introduced classification criteria for the major subgroups in 2017,1 but there is a need for contemporary real-world data to understand the burden – and well as new ways of assessing disease activity.
