Abstract
The outcome of paediatric acute lymphoblastic leukaemia is excellent, with a 90% overall survival rate. However, the overall survival of adults with acute lymphoblastic leukaemia with standard chemotherapy is only 40–50%. This outcome is typically worse with increasing age. Given this prognosis, novel therapies and strategies are needed to improve outcomes. In The Lancet Haematology, two different strategies are employed by the UKALL group: (1) the addition of the monoclonal anti-CD20 antibody, rituximab, to standard induction therapy in adults aged 25–65 years with precursor B-cell acute lymphoblastic leukaemia; 1 Marks DI Kirkwood AA Rowntree CJ et al. Addition of four doses of rituximab to standard induction chemotherapy in adult patients with precursor B-cell acute lymphoblastic leukaemia (UKALL14): a phase 3, multicentre, randomised controlled trial.

Rituximab is beneficial in acute lymphoblastic leukaemia but four doses during induction is likely to be insufficient.

Strategies to reduce infection-related TRM will further improve outcomes. Full-Text PDF Open Access
