[Analysis of ten cases of Acute lymphoblastic leukemia with non-KMT2A::AFF1 transcriptional variant 11q23 rearrangements].

The 11q23 rearrangement ALL with non-KMT2A::AFF1 transcript is mainly KMT2A::MLLT1, T-ALL is more common, and the rate of chromosomal karyotype detection is relatively low. Persistent positive KMT2A-r is unfavorable for patient survival, and allo-HSCT during the CR1 period may improve patient survival.
