Biomarkers for Clinical Classification and Outcomes of Immune Checkpoint Inhibitor-Related-Related Myocarditis in Lung Cancer

This study aims to investigate the clinical classification and outcome-related biomarkers of immune checkpoint inhibitor (ICI)-related myocarditis in patients with lung cancer.A total of 50 patients with ICI-related myocarditis will be enrolled, including 25 with severe/critical myocarditis and 25 with subclinical/mild myocarditis. Blood samples will be collected at baseline and at follow-up time points (3 days, 7 days, and before discharge). Traditional myocardial injury markers, iron metabolism-related markers, and immunological markers will be measured and compared between groups. Changes in biomarkers after treatment will also be assessed. Clinical information such as in-hospital mortality and 3-month survival rates will be integrated to develop a severity assessment model. This model aims to evaluate disease severity and prognostic risk accurately by combining biomarkers, enhancing their application in clinical management.

[68Ga]Ga-PentixaFor PET/CT in Acute Myocardial Inflammation

Acute myocardial inflammation is an heterogenic syndrome involving different clinical pathologies with different outcome. For the purpose of this study protocol, we focuse on three entities of this syndrome, namely the acute cellular cardiac allograft rejection (ACR), cardiac sarcoidosis (CS) and the immune checkpoint inhibitor induced myocarditis (ICIM), for which non-invasive diagnosis remains challenging. Since accurate diagnosis of myocardial inflammation in an early stage is crucial, this study aims to investigate the accuracy of \[68Ga\]Ga-PentixaFor as a marker of for the presence of inflammatory cells (T-lymphocytes and M1) in described patients. The identification of a correlation between \[68Ga\]Ga-PentixaFor myocardial accumulation with currently accepted diagnostic tools would open up new ways to non-invasively diagnose acute myocardial inflammation.
