CAR T and CAR NK cells in multiple myeloma: expanding the targets
Publication date: Available online 13 January 2020Source: Best Practice & Research Clinical HaematologyAuthor(s): Urvi A. Shah, Sham MailankodyAbstractMultiple myeloma (MM) is a haematologic malignancy with significant improvements in the overall survival over the last decade. However, patients still relapse and die due to a lack of treatment options. Ultimately, novel therapies with the potential for long term remissions are needed for patients with advanced MM. Research efforts for such immune therapies were not successful until recently when the first immunotherapies for MM were approved in 2015 and many more are under ...

Tracking of low disease burden in multiple myeloma: using mass spectrometry assays in peripheral blood
Publication date: Available online 11 January 2020Source: Best Practice & Research Clinical HaematologyAuthor(s): Jessica R. Chapman, Katie L. ThorenAbstractEfforts over the last 5 years have demonstrated that it is technically feasible to detect low levels of monoclonal proteins in peripheral blood using mass spectrometry. These methods are based on the fact that an M-protein has a specific amino acid sequence, and therefore, a specific mass. This mass can be tracked over time and can serve as a surrogate marker of the presence of clonal plasma cells. This review describes the use of mass spectrometry to detect M-proteins...

Contemporary treatment approaches to CMML – is allogeneic HCT the only cure?
Publication date: Available online 30 December 2019Source: Best Practice & Research Clinical HaematologyAuthor(s): Marie Robin, Raphael ItzyksonAbstractChronic Myelomonocytic Leukemias are frequently diagnosed in older adults. Their prognosis is heterogeneous, but several prognostic factors can identify patients with an expected survival of a few years only, including among younger patients eligible for allogeneic stem cell transplantation.Based on the retrospective data available, we discuss how to identify CMML patients for whom curative therapy must be envisaged. We emphasize that, although transplantation remains the o...

Moving towards a uniform risk stratification system in CMML - how far are we?
Publication date: Available online 6 December 2019Source: Best Practice & Research Clinical HaematologyAuthor(s): Onyee Chan, Eric PadronAbstractMany prognostic scoring systems have been developed for chronic myelomonocytic leukemia (CMML). Although these efforts have been informative, no single model has been considered the consensus for CMML prognostication and all models are only moderately prognostic. CMML clinical models utilize mainly hematology and morphology parameters to estimate risk. A better understanding of cytogenetics and the genomic landscape of CMML have resulted in integrated risk models such as CMML Prog...
