Key result
Grade 3-4 heart failure linked to ~566% higher mortality after ICI-associated myocarditis.
Why the study?
ICI-associated myocarditis is fatal and prone to affecting multiple organ systems, but multi-organ irAEs have not been fully studied in this setting.
Does the presence of multi-organ immune-related adverse events impact overall survival and disease severity in cancer patients with ICI-associated myocarditis?
Observational (n=46)
Yes
Does the presence of multi-organ immune-related adverse events impact overall survival and disease severity in cancer patients with ICI-associated myocarditis?
Effect estimate: HR 6.655 (95% CI 1.539-28.770)
p-value: p=0.011
In cancer patients with ICI-associated myocarditis, concurrent multi-organ irAEs are common and associated with more severe heart failure, which independently predicts poor overall survival.
No takes yet. Share an insight, caveat, or question.
Severe HF signals higher mortality in ICI-myocarditis; hypothesis-generating for multi-organ irAEs, needs prospective validation.
Xie et al. (2022) conducted an observational in Immune checkpoint inhibitor (ICI)-associated myocarditis (n=46). Heart failure (grade 3-4) was evaluated on Overall survival (OS) after myocarditis (HR 6.655, 95% CI 1.539-28.770, p=0.011). Heart failure (grade 3-4) was an independent risk factor for overall survival after immune checkpoint inhibitor-associated myocarditis (HR 6.655; 95% CI 1.539-28.770; p=0.011).
