  • Beschreibung: SummaryEarly recognition of children with chronic phase chronic myeloid leukaemia (CML‐CP) at risk for developing a lymphoid blast crisis (LyBC) is desirable, because therapy options in CML‐LyBC are limited. We used Multiplex Ligation‐dependent Probe Amplification to determine whether B‐cell lymphoid leukaemia‐specific copy number alterations (CNAs) (e.g. IKZF1, PAX5, CDKN2A deletions) could be detected in CML‐CP and may be used to predict disease progression to LyBC. CNAs were detected in all patients with CML‐LyBC, but in none of the 77 patients with CML‐CP. Based on this study we conclude that CNAs remain a hallmark of disease progression.
