Abstract

Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) is characterized by expression of oncogenic fusion product BCR-ABL1, resulting from reciprocal translocation between chromosomes 9 and 22 [t(9;22)(q34;q11.2)]. Previously perceived to confer poor outcome with at least 10 % lower chance of remission than standard-risk ALL. With the advent of targeted BCR-ABL specific tyrosine-kinase inhibitors (TKIs), higher remission rates were achieved, thus allowing more patients to proceed with the definitive treatment modality—allogeneic hematopoietic stem cell transplantation (alloHSCT). Prime challenges to treatment of Ph+ ALL include appropriate integration of TKIs into remission induction chemotherapeutic regimes, appropriate understanding and implementation of BCR-ABL monitoring for guiding therapeutic intervention(s), and minimizing transplant-related toxicities.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
