Transcriptional profiling directs the classification of acute leukemias of ambiguous lineage into AML, B-ALL, or T-ALL. [PDF]

Hemasphere
Abstract Acute leukemia of ambiguous lineage (ALAL) is a rare, poor‐prognosis acute leukemia subtype that cannot be assigned to a single hematopoietic lineage. Although ALAL patients are typically treated with acute myeloid leukemia (AML) or acute lymphoblastic leukemia (ALL) regimens, optimal treatment choice is hindered by their lineage ambiguity ...
