A decade ago, gene expression profiling (GEP) was successfully introduced in haematological research. Considering the heterogeneity of haematological malignancies, the growing arsenal of compounds, allowing targeted therapy, e.g. in myelodysplastic syndromes (MDS) or chronic myeloid leukaemia (CML), and the more differentiated indication to allogeneic stem cell transplantation, routine diagnostic procedures would highly benefit from an introduction of this novel methodology: by now, the majority of genetically defined leukaemia subtypes has been accurately reproduced on the basis of distinct gene expression patterns by various independent research groups. Moreover, classification of histomorphologically overlapping lymphoma subentities (e.g. Burkitt lymphoma and diffuse large B-cell lymphoma, DLBCL), was considerably improved by GEP. Beyond that, differential gene expression has provided the basis for assays being able to predict prognosis of individual patients as well as the response to specific treatment approaches, e.g. to lenalidomide in MDS. In a high proportion of Philadelphia positive acute lymphoblastic leukaemia (ALL) patients, prognostically adverse deletions of the IKZF1 gene coding for a specific transcription factor were identified with GEP analysis, which revealed new insights in the clinical variability of this disorder. Given these advantages of GEP, the introduction of this methodology in current diagnostic algorithms of haematological malignancies should further be validated in clinical studies.

Five-year survival has increased for many hematologic malignancies in the 21st century. However, whether this has translated into greater long-term survival is unknown. Here, we examine 10- and 20-year survival for patients with multiple myeloma (MM), acute lymphoblastic leukemia (ALL), acute myeloblastic leukemia (AML), chronic lymphoid leukemia (CLL), chronic myeloid leukemia (CML), non-Hodgkin lymphoma (NHL), and Hodgkin lymphoma (HL). Data were extracted from the Surveillance, Epidemiology, and End Results-9 database. Patients age 15+ with the above malignancies were included. The newly developed boomerang method was used to examine 10- and 20-year relative survival (RS) for patients in 2002-2006 and 2012-16. Ten and 20-year RS increased for each malignancy examined, with increases ranging from +4.4% units for 20-year RS for AML to +23.1% units for 10-year RS for CML. Ten year RS was >50% in 2012-16 for patients with CLL, CML, HL, NHL, and DLBCL, at 77.1%, 62.1%, 63.9%, 64.5%, and 63.0%, respectively. Survival dropped between 10 and 20 years after diagnosis for most malignancies. Long-term survival is increasing for common hematologic malignancies, but late mortality is an ongoing issue. Further study of long-term outcomes in curable malignancies to determine the reason for these later decreases in survival is indicated.
