Blood‐based cell‐free DNA and multitarget stool RNA screening tests to detect colorectal cancer: A systematic review

Cancer, Volume 132, Issue 11, 1 June 2026.
Abstract Two new tests, a cell‐free DNA (cfDNA) blood‐based test (BBT) and multitarget stool RNA (mt‐sRNA) test with in‐laboratory fecal immunochemical testing, were recently approved by the US Food and Drug Administration, and a second BBT is under review.

Efficacy of MAPK inhibitors in children with neurodegenerative Langerhans cell histiocytosis: Results from the European Consortium for Histiocytosis

HemaSphere, Volume 10, Issue 6, June 2026.
Abstract Neurodegenerative Langerhans cell histiocytosis (ND‐LCH) is a severe and debilitating complication of LCH with no effective treatment. In this study, we assessed the efficacy of MAPK inhibitors (MAPKi) in a large cohort of children with ND‐LCH. We included pediatric patients with ND‐LCH who received MAPKi between 2013 and 2025.
