FBXW7 and lymphoid neoplasm: While the WHO 5th edition emphasizes integrated morphologic, immunophenotypic, and genetic criteria for lymphoid neoplasms, our real‐world, multicenter dataset lacked uniform targeted sequencing (e.g., NOTCH1/FBXW7, PTEN, DNMT3A) and thus could not compare molecular landscapes between T‐LBL and T‐ALL.
