Özet

Background: Myositis may present as a treatment-related adverse event (TRAE) during immune checkpoint inhibitor (ICI) therapy. In the ARON-MOUSEION-017 meta-analysis, we aimed to assess the frequency of myositis among cancer patients treated with ICIs. Research design and methods: The present systematic review and meta-analysis was registered in PROSPERO with ID no. CRD420261278193. Embase, PubMed, Scopus and Web of Science databases were consulted, using Boolean terms and keywords ‘Immunotherapy,’ ‘Myositis’ and ‘Neoplasms.’ Results: For myositis of any grade, 13 studies were included, suggesting that heterogeneity across studies was high and statistically significant (p < 0.001; τ2 = 3.78; I2 = 95.3%, 95% CI [93.1%; 96.7%]), and the pooled proportion of patients affected by any-grade myositis treatment-related adverse events (TRAEs) was 4.2% (95% CI = [1.1%; 14.6%]). Conclusions: ICI-myositis often appears in concomitance with other immune-mediated conditions, such as myocarditis and myasthenia gravis. These events are clinically relevant, since they are often associated with more severe disease courses and unfavorable outcomes, increasing morbidity and mortality.
