Roadmap to cure multiple myeloma
Despite significant advances in the treatment of multiple myeloma which had led to unprecedented rates of
response and survival, patients still relapse, and cure remains elusive. We propose in this review a roadmap to
achieve the dream of cure for multiple myeloma based on five complementary strategies. First, to increase
knowledge about disease pathogenesis with a focus on the biology of circulating tumor cells, responsible for
dissemination and extramedullary disease, and minimal residual disease clones who represent the reservoir of
clonal evolution and disease recurrence. Second, to consider undetectable measurable residual disease (MRD),
defined by high-sensitive techniques, as the new endpoint of therapy. Third, to treat disease causation instead of symptomatology through early detection and intervention. Thereby, by treating high-risk smoldering myeloma
patients early, we may not only contribute to delay disease progression into active disease but also to increase the cure rates. Fourth, to use the most active scheme in standard-risk patients if the cure is in the horizon. Fifth, to investigate experimental therapies in newly diagnosed patients with high-risk MM, implementing early rescue
intervention strategies with the goal of eradicating all tumor clones, and achieving minimal residual disease

Utility of flow cytometry studies in the management of patients with multiple myeloma
Purpose of review: Although the input of multiparameter flow cytometry (MFC) into the clinical management of multiple myeloma (MM) patients has faced some reluctance, continuously growing evidence supports the utility of MFC in this disease.
Recent findings: MFC immunophenotyping of bone marrow and peripheral blood plasma cells affords cost-effective assessment of clonality, and provides prognostic information on the risk of progression in smoldering MM, and the identification of active MM patients with dismal outcome (e.g.: high numbers of circulating tumor cells) or long-term survival despite sub-optimal responses through the characterization of MGUS-like phenotypes. Extensive data indicates that MRD monitoring can be used as biomarker to evaluate treatment efficacy and act as surrogate for survival. The time has come to address within clinical trials, the exact role of baseline risk factors and MRD monitoring for tailored therapy in MM, which implies systematic usage of highly sensitive cost-effective, readily available and standardized MRD techniques such as MFC.
Summary: Next-generation MFC should be considered mandatory in the routine evaluation of MM patients both at diagnosis and after therapy, and represents an attractive technique to integrate with high-throughput DNA and RNA-seq methods to help understanding the mechanisms behind dissemination and chemoresistance of MM
CAR T-Cells in Multiple Myeloma Are Ready for Prime Time
The survival of patients with multiple myeloma (MM) has been dramatically improved in the last decade thanks to the incorporation of second-generation proteasome inhibitors (PI), immunomodulatory drugs (IMID), and, more recently, anti-CD38 monoclonal antibodies (MoAb). Nevertheless, still, a major proportion of MM patients will relapse, underscoring the need for new therapies in this disease. Moreover, survival in patients failing the current standard of care regimens (including PI, IMIDs, and anti-CD38 MoAb), which is now defined as triple-class refractory, remains dismal, and new drugs with different mechanism of action are needed. B-cell maturation antigen (BCMA)-targeted therapies and in particular chimeric antigen receptor T cell (CAR T-cell) treatment have emerged as promising platforms to overcome refractoriness to conventional drugs. In this manuscript, we review the current available data regarding CAR T-cell therapy for MM, with a special focus on target selection, clinical results, limitations, and future strategies
Abnormalities on 1q and 7q are associated with poor outcome in sporadic Burkitt's lymphoma. A cytogenetic and comparative genomic hybridization study
Comparative genomic hybridization (CGH) studies have demonstrated a high incidence of chromosomal imbalances in non-Hodgkin's lymphoma. However, the information on the genomic imbalances in Burkitt's Lymphoma (BL) is scanty. Conventional cytogenetics was performed in 34 cases, and long-distance PCR for t(8;14) was performed in 18 cases. A total of 170 changes were present with a median of four changes per case (range 1-22). Gains of chromosomal material (143) were more frequent than amplifications (5) or losses (22). The most frequent aberrations were gains on chromosomes 12q (26%), Xq (22%), 22q (20%), 20q (17%) and 9q (15%). Losses predominantly involved chromosomes 13q (17%) and 4q (9%). High-level amplifications were present in the regions 1q23-31 (three cases), 6p12-p25 and 8p22-p23. Upon comparing BL vs Burkitt's cell leukemia (BCL), the latter had more changes (mean 4.3 +/- 2.2) than BL (mean 2.7 +/- 3.2). In addition, BCL cases showed more frequently gains on 8q, 9q, 14q, 20q, and 20q, 9q, 8q and 14q, as well as losses on 13q and 4q. Concerning outcome, the presence of abnormalities on 1q (ascertained either by cytogenetics or by CGH), and imbalances on 7q (P=0.01) were associated with a short survival

Interpreting clinical trial data in multiple myeloma: translating findings to the real-world setting
Substantial improvements in survival have been seen in multiple myeloma (MM) over recent years, associated with the
introduction and widespread use of multiple novel agents and regimens, as well as the emerging treatment paradigm
of continuous or long-term therapy. However, these therapies and approaches may have limitations in the community
setting, associated with toxicity burden, patient burden, and other factors including cost. Consequently, despite
improvements in efficacy in the rigorously controlled clinical trials setting, the same results are not always achieved in
real-world practice. Furthermore, the large number of different treatment options and regimens under investigation in
various MM settings precludes the feasibility of obtaining head-to-head clinical trial data, and there is a temptation to
use cross-trial comparisons to evaluate data across regimens. However, multiple aspects, including patient-related,
disease-related, and treatment-related factors, can influence clinical trial outcomes and lead to differences between
studies that may confound direct comparisons between data. In this review, we explore the various factors requiring
attention when evaluating clinical trial data across available agents/regimens, as well as other considerations that may
impact the translation of these findings into everyday MM management. We also investigate discrepancies between
clinical trial efficacy and real-world effectiveness through a literature review of non-clinical trial data in relapsed/
refractory MM on novel agentâbased regimens and evaluate these data in the context of phase 3 trial results for
recently approved and commonly used regimens. We thereby demonstrate the complexity of interpreting data across
clinical studies in MM, as well as between clinical studies and routine-care analyses, with the aim to help clinicians
consider all the necessary issues when tailoring individual patientsâ treatment approaches
Chimeric antigen receptor T-cell therapy for multiple myeloma: a consensus statement from The European Myeloma Network
Adoptive cellular therapy using chimeric antigen receptor T-cell (CART) therapy is currently being evaluated in patients with relapsed /
refractory multiple myeloma (MM). The majority of CAR-T cell programs now being tested in clinical trials are targeting B-cell maturation antigen. Several recent phase I / II trials show promising preliminary results in
patients with MM progressing on proteasome inhibitors, immunomodulatory drugs and monoclonal antibodies targeting CD38. CAR-T cell therapy
is a potentially life-threatening strategy that can only be administered in
experienced centers. For the moment, CAR-T cell therapy for MM is still
experimental, but once this strateg
