This systematic review evaluated empirical studies examining motor skills in children during and following treatment for acute lymphoblastic leukemia. Most studies indicated that children on-treatment display poorer gross and fine motor abilities than healthy peers, but generally have intact visual-motor integration skills. Studies have reported gross motor difficulties in 5-54% of survivors. There is some limited evidence for long-term fine motor deficits. The evidence for visual-motor integration difficulties in the survivor population is less consistent. Larger studies with a longitudinal design are needed to further specify the onset and timing of motor difficulties and ascertain risk factors.

The treatment of Philadelphia chromosome-positive B-cell acute lymphoblastic leukemia (Ph+ B-cell ALL) has seen substantial progress over the past two decades. The introduction of tyrosine kinase inhibitor (TKIs) has resulted in dramatic improvements in long-term survival. Allogeneic hematopoietic stem cell transplantation (allo-HSCT), with its curative potential, has always been an integral part of the treatment algorithm of Ph+ ALL.

Recent studies have demonstrated the association between constitutional ring chromosome 21 (r(21)c) and the development of B-cell acute lymphoblastic leukemia (B-ALL) with intrachromosomal amplification of chromosome 21 (iAMP21). iAMP21 acts as a driver which is often accompanied by secondary alterations that influence disease progression. Here, we report an atypical case of iAMP21 B-ALL with a unique molecular profile in the context of r(21)c.

Genetic studies of haematological cancers have pointed out the heterogeneity of leukaemia in its different subpopulations, with distinct mutations and characteristics, impacting the treatment response. Next-generation sequencing (NGS) and genome-wide analyses, as well as single-cell technologies, have offered unprecedented insights into the clonal heterogeneity within the same tumour. A key component of this heterogeneity that remains unexplored is the intracellular metabolome, a dynamic network that determines cell functions, signalling, epigenome regulation, immunity and inflammation.

T-cell acute lymphoblastic leukemia (T-ALL), which constitutes of 10-15% of all pediatric ALL cases, is known for its complex pathology due to pervasive genetic and chromosomal abnormalities. Although most children are successfully cured, chromosomal rearrangements involving the KMT2A gene is considered a poor prognostic factor. In a cohort of 171 pediatric T-ALL samples we have studied differences in gene and splice variant patterns in KMT2A rearranged (KMT2A-r) T-ALL compared to KMT2A negative (KMT2A-wt) T-ALL samples.

Purpose: Lumbar puncture is a frequently performed procedure for patients undergoing treatment for acute lymphoblastic leukemia. This brief procedure is frequently performed with sedation in young patients but with only local anesthesia in adults. Adolescent and young adult patients may be cared for by physicians with different training backgrounds and sedation preferences, making the utilization of sedation for lumbar punctures variable among providers.
