Association of Ferritin Levels With Cytokine Release Syndrome in CAR T‐Cell Therapy: A Systematic Review and Meta‐Analysis
ABSTRACT Background Ferritin elevation is frequently observed during cytokine release syndrome (CRS) following CAR T‐cell therapy; however, its independent clinical utility as a predictive or prognostic biomarker remains uncertain. We performed a systematic review critically evaluating the timing‐specific and context‐dependent role of ferritin in CRS risk stratification and outcomes. Methods We systematically searched PubMed, Web of Science, and Scopus for studies evaluating ferritin in CAR T‐cell recipients. We pe …
