The 3-year EFS rate was 59%, and the median OS was not reached. , The median WBC count at diagnosis is much higher for T-ALL (>50,000/µL) than for B-ALL (<10,000/µL), and there is no consistent effect of WBC count at diagnosis on prognosis for T-ALL.[34-41].

The COG reported that risk group classification at the time of initial diagnosis was prognostically significant after relapse; patients who met National Cancer Institute (NCI) standard-risk criteria at initial diagnosis fared better after relapse than did NCI high-risk patients. TBI for all but the youngest children (age <3 or 4 years) remains standard of care in most centers in North America and Europe. Shago M, Abla O, Hitzler J, et al.

[28-30], Multiple retrospective studies have established that adolescents aged 16 to 21 years have a better outcome when treated on pediatric versus adult protocols. A meta-analysis of randomized trials compared thiopurines and found the following: Thioguanine did not improve the overall EFS, although particular subgroups may benefit from its use. More than 95% of children with ALL enter remission after 1 month of induction treatment. Participants who received testicular radiation therapy achieved a 5-year EFS rate of 73% versus 61% for those who did not receive radiation (. [, An analysis of data from the Center for International Blood and Marrow Transplant Research (CIBMTR) on 27 Down syndrome patients with ALL who underwent hematopoietic stem cell transplantation (HSCT) between 2000 and 2009 substantiated this finding. standard maintenance backbone, although the benefit of these pulses within the context of contemporary multiagent chemotherapy regimens remains controversial.

The children were younger than 16 years of age and had a diagnosis of ALL de novo .  In addition to the TCF3-HLF fusion, the genomic landscape of this ALL subtype was characterized by deletions in genes involved in B-cell development (PAX5, BTG1, and VPREB1) and by mutations in RAS pathway genes (NRAS, KRAS, and PTPN11). : Mercaptopurine Ingestion Habits, Red Cell Thioguanine Nucleotide Levels, and Relapse Risk in Children With Acute Lymphoblastic Leukemia: A Report From the Children's Oncology Group Study AALL03N1. : Transitional pre-B-cell acute lymphoblastic leukemia of childhood is associated with favorable prognostic clinical features and an excellent outcome: a Pediatric Oncology Group study.

The half-life of Erwinia L-asparaginase (0.65 days) is much shorter than that of native E. coli (1.2 days) or pegaspargase (5.7 days). This study demonstrated that long-term salvage of patients failing CD19-targeted CAR T cells can occur with CD22-targeted CAR T cells plus HSCT. Treatment involves a combination of medicines.
