Molecular diagnostics have an increasing impact on diagnosis, risk stratification and targeted treatment in haemato-oncology. In the framework of a pilot study for the implementation of next-generation sequencing in the Belgian healthcare system, the Commission of Personalised Medicine was founded to give professional and evidence-based advice on the molecular analysis in haemato-oncology. This paper describes its recommendations for NGS analysis in myeloid malignancies. In addition, the minimally required set of genes that must be analysed is defined and algorithms for molecular workflow in myeloid malignancies are proposed.

In this hematocase, a patient is presented with a spontaneous rupture of the spleen due to massive splenomegaly caused by a previously undiagnosed diffuse large B-cell lymphoma. Diagnosis and differentiation of this non-Hodgkin lymphoma is discussed with attention for the prognostic implications of the results. The association between spontaneous rupture of the spleen and haematological malignancies is further explored by means of earlier described cases. A take home message is given regarding this rare initial presentation of a lymphoma since immediate surgical intervention is imperative in these cases.

For most haematological disease entities whole genome and/or exome sequencing efforts identified a core set of recurrently mutated genes. Multiplex DNA mutation screening proves to be highly applicable for myeloid malignancies, since mutations in many genes, e.g. FLT3, NPM1, CEBPA, KIT, DNMT3A, IDH1, IDH2, TET2, ASXL1, RUNX1, SF3B1, SRSF2, U2AF1, ZRSR2, TP53, STAG2, SMC1A, SMC3, RAD21, PHF6, RAS, EZH2, ETV6, JAK2, MPL, CALR, SETBP1, CSF3R, are described to be significantly associated with diagnosis, disease subtyping, prognostication, and/or for tailoring therapy. Obviously, their analysis is no longer feasible using conventional, single gene molecular diagnostic techniques, urging the use of a multi-gene ‘pan-myeloid’ Next Generation Sequencing panel.

In the past few years the cost of next generation sequencing decreased substantially and the technology has significantly matured, allowing for its introduction into clinical practice. For most haematological disease entities whole genome and/or exome sequencing efforts identified a core set of recurrently mutated genes. Several of these genes are expected to be included in the upcoming revision of the 2008 edition of the World Health Organisation classification of haematological malignancies. Next generation sequencing technology allows transforming current single gene mutation analysis into multiplexed mutational profiling. Next generation ‘deep’ sequencing is a promising new tool to monitor minimal disease burden and to detect mutations within malignant subclones. With current platforms point mutations can be detected with a sensitivity of 1–5% mutant DNA. For indel mutations or clonal IG/TCR rearrangements sensitivity in the range of 10−5 can be reached. In this review we will highlight the opportunities and challenges of the introduction of next generation sequencing technology into a setting where it will contribute significantly to individual patient cancer management.
