Modern risk classification systems continue to utilize clinical factors such as age and presenting WBC count, and in addition, incorporate cytogenetics and genomic lesions of leukemia cells at diagnosis (e.g., favorable and unfavorable translocations) and response to therapy based on detection of MRD at end of induction (and in some cases at later time points). The median age at symptom onset was 16 years. Dexamethasone was associated with higher incidence of life-threatening events (primarily infections), resulting in a significantly higher induction death rate (2.5% for dexamethasone vs. 0.9% for prednisone; There was no difference in rates of osteonecrosis between the randomized groups.

[75] DUX4-rearranged cases show a distinctive gene expression pattern that was initially identified as being associated with focal deletions in ERG,[75-78] and one-half to more than two-thirds of these cases have focal intragenic deletions involving ERG that are not observed in other ALL subtypes.

These include the chemotherapy drugs L-asparaginase and vincristine, and a steroid drug (such as dexamethasone).

Some trials also suggest that dexamethasone during induction may be associated with more toxicity than prednisone, including higher rates of infection, myopathy, and behavioral changes. Approaches have traditionally included the use of drug combinations distinct from the first attempt at treatment; these regimens often contain newer agents under investigation in clinical trials.

Evidence (intensification for standard-risk ALL): In high-risk patients, a number of different approaches have been used with [, One study showed that in 46 patients with increasing recipient chimerism, the 31 patients who underwent immune suppression withdrawal, donor lymphocyte infusion, or both therapies had a 3-year EFS rate of 37% versus 0% in the nonintervention group (, Other studies have shown better-than-expected rates of survival of pre-HSCT, MRD-positive patients when tapering of immunosuppression medication has occurred for MRD detected after HSCT.[.

On some studies, boys are treated longer than girls;[61] on others, there is no difference in the duration of treatment based on sex.

Dexamethasone was associated with a superior event-free survival (EFS). Help make it a reality. relapse depend on the timing of the relapse. [4] Childhood and adolescent cancer survivors require close monitoring because cancer therapy side effects may persist or develop months or years after treatment. [43] Therefore, standard-risk patients with higher levels of end-induction MRD are not treated with the approaches described for standard-risk patients who have low end-induction MRD, but are usually treated with high-risk regimens. [4,106,107,110,116], Although the results of several retrospective studies suggest that CRLF2 abnormalities may have adverse prognostic significance in univariate analyses, most do not find this abnormality to be an independent predictor of outcome.

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.

Some groups, such as St. Jude Children's Research Hospital (SJCRH) and the Dutch Childhood Oncology Group (DCOG), do not use cranial radiation therapy in first-line treatment of ALL, and other groups, such as DFCI, COG, and BFM, are now limiting radiation therapy to patients with very high-risk features or CNS3 disease. Importantly, the TP53 alterations observed in low-hypodiploid ALL are also present in nontumor cells in approximately 40% of cases, suggesting that these mutations are germline and that low-hypodiploid ALL represents, in some cases, a manifestation of Li-Fraumeni syndrome. : An international study of intrachromosomal amplification of chromosome 21 (iAMP21): cytogenetic characterization and outcome. : Near-triploidy and near-tetraploidy in childhood acute lymphoblastic leukemia: association with B-lineage blast cells carrying the ETV6-RUNX1 fusion, T-lineage immunophenotype, and favorable outcome.

Patients classified as standard-risk high receive backbone chemotherapy as per high-risk B-ALL regimens with intensified consolidation, interim maintenance, and reinduction therapy. This treatment involves engineering T cells with a CAR that redirects T-cell specificity and function. Mullighan CG, Goorha S, Radtke I, et al. [64] However, even with this intensified approach, reported long-term EFS rates range from 30% to 50% for this patient subset.[33,64]. Caution is needed in interpreting these results because of the short median follow-up time and because the outcomes of patients who received imatinib on this trial were inferior to the outcomes of imatinib-treated patients reported in previous trials. In addition to therapy delivered directly to the brain and spinal fluid, systemically administered agents are also an important component of effective CNS prophylaxis.

Treatment for pediatric ALL typically consists of induction therapy with steroids, vincristine, and asparaginase with or without anthracycline, followed by multi-agent consolidation including high-dose methotrexate and re-induction therapy.
