The clinical impact of IKZF1 deletions in paediatric B‐cell precursor acute lymphoblastic leukaemia is independent of minimal residual disease stratification in Nordic Society for Paediatric Haematology and Oncology treatment protocols used between 1992 and 2013

Abstract: and \ingegerd.ofverholm@ki.se *These first authors contributed equally to this work. SummaryPaediatric B-cell precursor acute lymphoblastic leukaemias (BCP ALL) with IKZF1 deletions (ΔIKZF1) are associated with a poor outcome. However, there are conflicting data as to whether ΔIKZF1 is an independent risk factor if minimal residual disease (MRD) and other copy number alterations also are taken into account. We investigated 334 paediatric BCP ALL, diagnosed 1992-2013 and treated according to Nordic Society for … Show more

“…Also, co-occurrence of deletions in the autosomal IKZF1 gene with deletions in PAR1, resulting in P2RY8 -CRLF2 fusion, has been associated with poor prognosis in children with B-cell acute lymphoblastic leukemia [Olsson et al, 2015].…”

“…Выявленная нами частота делеций IKZF1 у боль-ных ВП-ОЛЛ (10,6 %) оказалась несколько ниже, чем данные, полученные в Швеции (15,0 %) [45], Нидер-ландах (13,7 %) [11], Италии (13,2 %) [27] и Германии (12,1 %) [24], но близка к результатам, опубликован-ным исследователями из Тайваня (10,7 %) [44]. В то же время у детей с ОЛЛ в Чехии была получена даже более низкая частота распространенности делеций IKZF1 (6,8 %) [46].…”

“…Неоднократно в рамках разных терапевтических протоколов показано, что делеции гена IKZF1 незави-симо от их типа и количества вовлеченных экзонов [13] являются фактором, ассоциированным с неблагопри-ятным исходом при BCR-ABL1-негативном ВП-ОЛЛ у детей [10,11,24,26,27,45]. Наши данные подтвер-дили эти более ранние находки.…”
