“…Swansbury GJ et al, showed that the best outcome was for patients aged 1-9 yr, with low WBC, and with absence of central nervous system disease or presence of trisomy 8 (85). Translocation t(9;11)(p22;q23) associated with additional chromosomal aberrations and ⁄ or a FAB subtype different from M5 could be considered as an adverse prognostic factor (82,88,89). t(6;11)(q27;q23) t(6;11)(q27;q23) has been mainly found in AML-M5 and M4 and was associated with a poor prognosis.…”

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease accounting for 15–20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. This article focuses on the significance of cytogenetic analysis in pediatric AML supporting the importance of cytogenetic analysis in the pathogenesis, diagnosis, prognosis, follow‐up and treatment selection in childhood AML. It reviews in detail the types and frequencies of most common chromosomal aberrations, their molecular background, their correlation with French American British (FAB) subtypes and age distribution and their prognostic relevance. It also summarizes some less frequent or rare chromosome aberrations in which the prognostic classification has not been determined yet owning to the small number of patients and the variable treatment modalities used in different study groups. Furthermore, it discusses the association of specific chromosome rearrangements with prenatal exposure to carcinogenic agents or therapeutic agents and highlights the ongoing and future research on pediatric AML in the evolving field of Cytogenetics.

“…Генетичні дослідження, проведені нами у представлених дітей, виявили моносомію 7 та t (9,11). За повідомленнями частини дослідни ків, пацієнти з такими генетичними змінами мають поганий прогноз, вони частіше є рези стентними до лікування, схильні до рецидивів, навіть після ало ТГПСК [11,31]. Також зустрі чаються публікації, де пацієнти з ГМЛ і t (9,11) мали добрий прогноз перебігу хвороби [55].…”

“…While the National Comprehensive Cancer Network guidelines labeled t(9;11)-positive AML as an intermediate-risk disease, many studies confirmed an aggressive clinical course for this biologic entity. 2,3 In the following case, the biologic mimicry between t(9;11)-positive AML and juvenile myelomonocytic leukemia (JMML) lent t(9;11)-positive AML a peculiar adverse prognostic feature. Notably, the distortion of the clinical picture by the leukemic overlap led to a profoundly severe course due to hampering the undertaking of the correct treatment that resulted in mortality.…”

KMT2A-MLLT3 AML Masquerading as JMML may Disguise Fatal Leukemia

We present a mortality case showcasing t(9;11)-positive acute myeloid leukemia/juvenile myelomonocytic leukemia (AML/JMML) overlap to shed light on this lethal molecular subtype of AML. In this case, the flawed assumption that JMML was to blame impeded the prompt undertaking of appropriate treatment for AML in our 14-month-old patient. This article aims to scrutinize the catastrophic sequel of such an overlap in leukemia and refutes the contemporary diagnostic methods.
