Chronic lymphocytic leukaemia (CLL) is the most common blood cancer in the UK, with an incidence of >3500 newly diagnosed cases per year resulting in >1000 deaths. Disease prevalence increases with age, where the majority of patients are >65 years old [1]. CLL is a largely indolent disease and is routinely staged according to the Binet system as follows; stage A (involving 0-2 lymphoid sites), stage B (involving 2-5 lymphoid cites) and stage C (platelets < 1x1011/L or haemoglobin <10g/dL), the latter stage reflecting loss of bone marrow function [2]. Whilst for some stage A patients, the disease may remain stable for many decades (median life expectancy of 13 years), for others the disease progresses more rapidly [3]. This observation likely reflects the genetic and molecular heterogeneity of CLL. As such there are several prognostic risk factors used to stratify newly diagnosed patients, which include; trisomy-12, 13q/17p/11q23 deletion, advanced stage, males>females, unmutated VH Ig genes, raised lactate dehydrogenase activity and expression of Zap70 and CD38 [4]. CLL is traditionally treated with a combination of chemotherapeutic reagents, namely, Fludarabine/ Cyclophosphamide/Rituximab (FCR), however treatment remains challenging within the elderly population [1]. Lately the Brutan’s tyrosine kinase inhibitor, Ibrutinib, has shown great promise for the treatment of CLL [5]. However, exceptions are identified as well as treatment resistance prompting further research into CLL treatment strategies [6].
