Despite the development of novel treatments in the past 15 years, many blood
cancers still remain ultimately fatal and difficult to treat, particularly acute
myeloid leukaemia (AML) and multiple myeloma (MM). While significant progress has
been made characterising small-scale genetic mutations and larger-scale
chromosomal translocations that contribute to the development of various blood
cancers, less is understood about the complex microenvironment of the bone marrow
(BM), which is known to be a key player in the pathogenesis of chronic
lymphocytic leukaemia (CLL), AML and MM. This niche acts as a sanctuary for the
cancerous cells, protecting them from chemotherapeutics and encouraging clonal
cell survival. It does this by upregulating a plethora of signalling cascades
within the malignant cell, with the phosphatidylinositol-3-kinase (PI3K) pathway
taking a critical role. This review will focus on how the PI3K pathway influences
disease progression and the individualised role of the PI3K subunits. We will
also summarise the current clinical trials for PI3K inhibitors and how these
trials impact the treatment of blood cancers.
