- P>A proportion of cytogenetic abnormalities in myelodysplastic syndromes (MDS) and acute myeloid leukaemia (AML) may escape detection by high-resolution genomic technologies, but can be identified by conventional cytogenetic and molecular analysis. Here, we report the detection of a reciprocal translocation t(7;21)(p22;q22) in the marrow of two adults with MDS and AML, using conventional cytogenetic analysis and fluorescence-in situ-hybridization (FISH). Reverse-transcription polymerase chain reaction (RT-PCR) and sequence analysis identified a fusion between RUNX1 and the gene encoding ubiquitin specific peptidase-42 (USP42), with splice-variants and variable break-points within RUNX1. Combined cytomorphology and FISH studies in MDS marrow revealed abnormal RUNX1 signals within megakaryocytes, suggesting that the acquisition of t(7;21)(p22;q22) does not confer complete differentiation arrest and may represent an early genetic event in leukaemogenesis. Single nucleotide polymorphism-arrays failed to detect additional sub-microscopic genomic changes predisposing to or associated with t(7;21). Molecular analysis of 100 MDS and AML marrow specimens by RT-PCR did not reveal new cases with the RUNX1-USP42 fusion. Thus, our studies have identified t(7;21)(p22;q22) as a rare but recurrent abnormality in MDS/AML, with the existence of alternative spliced forms of the RUNX1-USP42 transcript in different patients. Further studies are required to identify the potential contribution of these splice-variants to disease heterogeneity.

- FK506-binding protein-like (FKBPL) has established roles as an anti-tumor protein, with a therapeutic peptide based on this protein, ALM201, shortly entering phase I/II clinical trials. Here, we evaluated FKBPL's prognostic ability in primary breast cancer tissue, represented on tissue microarrays (TMA) from 3277 women recruited into five independent retrospective studies, using immunohistochemistry (IHC). In a meta-analysis, FKBPL levels were a significant predictor of BCSS; low FKBPL levels indicated poorer breast cancer specific survival (BCSS) (hazard ratio (HR) = 1.30, 95% confidence interval (CI) 1.14-1.49, p < 0.001). The prognostic impact of FKBPL remained significant after adjusting for other known prognostic factors (HR = 1.25, 95% CI 1.07-1.45, p = 0.004). For the sub-groups of 2365 estrogen receptor (ER) positive patients and 1649 tamoxifen treated patients, FKBPL was significantly associated with BCSS (HR = 1.34, 95% CI 1.13-1.58, p < 0.001, and HR = 1.25, 95% CI 1.04-1.49, p = 0.02, respectively). A univariate analysis revealed that FKBPL was also a significant predictor of relapse free interval (RFI) within the ER positive patient group, but it was only borderline significant within the smaller tamoxifen treated patient group (HR = 1.32 95% CI 1.05-1.65, p = 0.02 and HR = 1.23 95% CI 0.99-1.54, p = 0.06, respectively). The data suggests a role for FKBPL as a prognostic factor for BCSS, with the potential to be routinely evaluated within the clinic.

Societal challenges of precision medicine : Bringing order to chaos

Journal article (peer-reviewed)abstract
- The increasing number of drugs targeting specific proteins implicated in tumourigenesis and the commercial promotion of relatively affordable genome-wide analyses has led to an increasing expectation among patients with cancer that they can now receive effective personalised treatment based on the often complex genomic signature of their tumour. For such approaches to work in routine practice, the development of correspondingly complex biomarker assays through an appropriate and rigorous regulatory framework will be required. It is becoming increasingly evident that a re-engineering of clinical research is necessary so that regulatory considerations and procedures facilitate the efficient translation of these required biomarker assays from the discovery setting through to clinical application. This article discusses the practical requirements and challenges of developing such new precision medicine strategies, based on leveraging complex genomic profiles, as discussed at the Innovation and Biomarkers in Cancer Drug Development meeting (8th–9th September 2016, Brussels, Belgium).
