Lancet Oncol 2 (7): 429-36, 2001. [116], MRD levels obtained 10 to 12 weeks after the start of treatment (end-consolidation) have also been shown to be prognostically important; patients with high levels of MRD at this time point have a significantly inferior EFS compared with other patients.

J Pediatr Hematol Oncol 28 (8): 486-95, 2006. The corticosteroid randomization was closed early for patients aged 10 years or older at diagnosis because of excessive rates of osteonecrosis in patients randomly assigned to dexamethasone; however, it did not appear that there was any EFS benefit associated with dexamethasone in these older patients (5-year EFS rates of 73.1% with dexamethasone and 73.9% with prednisone; A randomized comparison of IV pegaspargase versus IM native. 6 mg/m2, per os, in two divided doses per day q12 hours.

On the Interfant-06 study, infants considered to be high risk (all of the following: About one-half of the high-risk patients did not proceed to transplant in the first CR primarily because of early relapse. [61-65] Clinical trials have also demonstrated that many pediatric patients with Ph+ ALL will have a comparable EFS using chemotherapy and a tyrosine kinase inhibitor than with transplant. : Leukemia and lymphoma in ataxia telangiectasia. For children whose leukemia comes back sooner after starting treatment, or for children with T-cell ALL who relapse, a stem cell transplant may be considered, especially if the child has a brother or sister who is a good tissue type match. [76,99,100,103,116,121-127]; [128][Level of evidence: 2Di] 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 deletion. Blood 92 (2): 411-5, 1998. MRD data were unavailable in this study population, so they were not included in the analysis of prognostic factors.

Permission to use images outside the context of PDQ information must be obtained from the owner(s) and cannot be granted by the National Cancer Institute. [26] These cases may be interpretable based on the pattern of gains and losses of specific chromosomes (hyperdiploidy with two and four copies of chromosomes rather than three copies).

[154,155] ABD is characteristic of early thymic precursor cells, and many of the T-ALL patients with ABD have an immunophenotype consistent with the diagnosis of early T-cell precursor phenotype. Pretreatment risk factors associated with a worse outcome were obesity and the presence of the Ph-like expression signature.

Weng AP, Ferrando AA, Lee W, et al. Patients with high MRD after induction (≥0.01%) had a very poor EFS rate of 26.7% at 5 years, with no difference between the patients who received HSCT and the patients who received chemotherapy. [1] However, with current treatment regimens, outcomes for children with T-ALL are now approaching those achieved for children with B-ALL. A SJCRH study of 567 adult long-term survivors of childhood ALL underwent neurocognitive testing (mean time from diagnosis, 26 years).[. Mehta J, Powles R, Treleaven J, et al.

Background: This study evaluates the main (para)clinical aspects and outcomes in a group of Romanian children diagnosed with acute lymphoblastic leukemia (ALL), under the conditions of antileukemic treatment according to an adapted ALL IC Berlin–Frankfurt–Munster (BFM) 2002 protocol. J Clin Oncol 25 (15): 2063-9, 2007. [6] Factors affecting prognosis are grouped into the following three categories: As in any discussion of prognostic factors, the relative order of significance and the interrelationship of the variables are often treatment dependent and require multivariate analysis to determine which factors operate independently as prognostic variables. The presence of detectable MRD post-HSCT has been associated with an increased risk of subsequent relapse. [41] It does not appear that the presence of secondary cytogenetic abnormalities, such as deletion of ETV6 (12p) or CDKN2A/B (9p), impacts the outcome of patients with the ETV6-RUNX1 fusion. : The 2016 revision to the World Health Organization classification of myeloid neoplasms and acute leukemia.
