A study of 50 patients eligible for HSCT after 4-1BB-based CAR T-cell therapy reported the following results (, Patients who lost CAR T-cell function before 63 days after therapy had improved leukemia-free survival (LFS) if they underwent HSCT, compared with those who did not undergo HSCT (, Patients with no prior history of HSCT had an improved LFS with a planned HSCT, with a trend toward significance (. Patients who have a nontraumatic diagnostic lumbar puncture may be placed into one of three categories according to the number of WBC/L and the presence or absence of blasts on cytospin as follows: Children with ALL who present with CNS3 disease at diagnosis are at a higher risk of treatment failure (both within the CNS and systemically) than are patients who are classified as CNS1 or CNS2. : Augmented post-induction therapy for children with high-risk acute lymphoblastic leukemia and a slow response to initial therapy. : An international study of intrachromosomal amplification of chromosome 21 (iAMP21): cytogenetic characterization and outcome. : Acute neurotoxicity in children with B-precursor acute lymphoid leukemia: an association with intermediate-dose intravenous methotrexate and intrathecal triple therapy--a Pediatric Oncology Group study.

[78,107,108,111,127,132-138]; [139][Level of evidence B4] However, the prognostic significance of IKZF1 may not apply equally across ALL biological subtypes, as illustrated by the apparent lack of prognostic significance in patients with ERG deletions. J Natl Cancer Inst 111 (12): 1350-1357, 2019. [67] In other trials, there is no difference in the duration of treatment based on sex. J Clin Oncol 36 (22): 2306-2314, 2018.

Outcomes in children with Down syndrome and ALL have often been reported as somewhat inferior to outcomes in children without Down syndrome,[61-65] although on some studies, patients with Down syndrome appeared to fare as well as those without Down syndrome. Blood 119 (8): 1872-81, 2012. The major immunophenotypic subtypes of B-ALL are as follows: Approximately three-quarters of patients with B-ALL have the common precursor B-cell immunophenotype and have the best prognosis.

The total systemic exposure to calaspargase pegol was greater than for pegaspargase. Minson KA, Prasad P, Vear S, et al. [37] However, in a BFM study of patients with B-ALL who experienced a late first marrow relapse, IKZF1 deletions were not prognostically significant.[21]. Blood 110 (12): 4022-9, 2007. The genomic alterations associated with the MPAL, B/myeloid, NOS (B/M MPAL) and MPAL, T/myeloid, NOS (T/M MPAL) entities are distinctive, as described below: A number of polymorphisms of genes involved in the metabolism of chemotherapeutic agents have been reported to have prognostic significance in childhood ALL. The 5-year EFS and OS rates are 35% to 40% for infants with KMT2A-rearranged ALL. In subset analyses, the addition of bortezomib to the four-drug reinduction platform did not result in significantly better second CR rates for patients with either very early relapses (<18 months from diagnosis) or early relapses (1836 months from diagnosis) when compared with historical controls. Eur J Cancer 49 (6): 1346-55, 2013. Patients with an isolated CNS relapse who show greater than 0.01% MRD in a morphologically normal marrow have a worse prognosis (5-year EFS rate, 30%) than do patients with either no MRD or MRD less than 0.01% (5-year EFS rate, 60%).[192]. High-dose methotrexate was also associated with a superior 5-year OS (, Patients with MRD less than 0.01% at end of induction had a 5-year EFS rate of 87%, compared with 74% for those with MRD 0.01% to 0.1%. Qian M, Cao X, Devidas M, et al. [70][Level of evidence B4] Extending the duration of maintenance therapy beyond 3 years After induction, 230 patients were randomly assigned to receive either calaspargase pegol every 3 weeks (10 doses) or pegaspargase every 2 weeks (15 doses).[. There was no significant difference in EFS between patients who received one and those who received two delayed intensification phases. Relling MV, Hancock ML, Rivera GK, et al. Patients who are CD22 negative at diagnosis (or have unknown CD22 status) are not eligible to be randomized, and they are removed from protocol therapy. Swerdlow SH, Campo E, Harris NL, et al., eds. However, the chemotherapy-only strategy resulted in a significantly worse outcome for patients with early-combined relapses (marrow plus extramedullary site) and low end-reinduction MRD. : Prognostic value of rare IKZF1 deletion in childhood B-cell precursor acute lymphoblastic leukemia: an international collaborative study. spared more toxic treatments, while allowing children with a Arch Dis Child 101 (5): 449-54, 2016.
