Evaluating concordance between International Myeloma Working Group (IMWG) frailty score and simplified frailty scale among older adults with multiple myeloma.

Introduction: Several frailty assessment tools exist for classifying older adults with multiple myeloma (MM) by their frailty status, such as the International Myeloma Working Group (IMWG) frailty score and the simplified frailty scale. The level of agreement between the IMWG frailty score and the simplified frailty scale remains unknown.

Materials And Methods: In a cross-sectional analysis of a prospective cohort study, we identified adults ≥50y initiating a new treatment regimen for MM who underwent a baseline geriatric assessment (GA).

Hospital Associated Disability among Older Adults with Plasma Cell Disorders Receiving Autologous Stem Cell Transplant.

Increasing number of older adults with Plasma Cell Disorders (PCDs) are receiving autologous stem cell transplant (ASCT) in the US. Hospital associated disability (HAD) is a common complication associated with acute care hospitalization among older adults. To estimate the prevalence and prognostic significance of HAD among older adults with MM undergoing ASCT.

Anthropometric traits and risk of multiple myeloma: differences by race, sex and diagnostic clinical features.

Background: Obesity is an established modifiable risk factor for multiple myeloma (MM). However, associations of obesity and MM risk in Black populations, for whom obesity and MM are more common, is less clear.

Methods: Using participants enrolled in the Integrative Molecular And Genetic Epidemiology study, we evaluated the association of anthropometric traits with MM risk overall, stratified by race and sex.

Understanding health outcome preferences of older adults diagnosed with multiple myeloma.

Introduction: Health outcome preferences of older adults with cancer vary based on burden/intensity of treatment and its impact on health outcomes such as survival, quality of life, and functional and cognitive well-being. We studied the association between age and health outcome preferences of adults with multiple myeloma (MM).

Materials And Methods: Using a single center prospective cohort study, we identified adults ≥50y with MM who underwent geriatric assessment (GA) within 30 days of initiating a new line of therapy.

Daratumumab-based quadruplet therapy for transplant-eligible newly diagnosed multiple myeloma with high cytogenetic risk.

In the MASTER study (NCT03224507), daratumumab+carfilzomib/lenalidomide/dexamethasone (D-KRd) demonstrated promising efficacy in transplant-eligible newly diagnosed multiple myeloma (NDMM). In GRIFFIN (NCT02874742), daratumumab+lenalidomide/bortezomib/dexamethasone (D-RVd) improved outcomes for transplant-eligible NDMM. Here, we present a post hoc analysis of patients with high-risk cytogenetic abnormalities (HRCAs; del[17p], t[4;14], t[14;16], t[14;20], or gain/amp[1q21]).

Subsequent therapy and outcomes in patients with newly diagnosed multiple myeloma experiencing disease progression after quadruplet combinations.

The combination of anti-CD38 monoclonal antibodies to a proteasome inhibitor, an immunomodulatory agent and dexamethasone (quadruplet-QUAD) in sequence with autologous stem cell transplantation (ASCT) leads to deep and durable responses in newly diagnosed multiple myeloma (NDMM). Disease progression in the first year post-QUADs is uncommon. We analysed 274 consecutive NDMM patients treated with QUADs + ASCT.

Minimal residual disease response-adapted therapy in newly diagnosed multiple myeloma (MASTER): final report of the multicentre, single-arm, phase 2 trial.

Background: For patients with newly diagnosed multiple myeloma, reaching minimal residual disease (MRD) negativity after treatment is associated with improved outcomes; however, the use of MRD to modulate therapy remains elusive. We present the final analysis of the MASTER trial of daratumumab, carfilzomib, lenalidomide, and dexamethasone (Dara-KRd) therapy in patients with newly diagnosed multiple myeloma, in which MRD status is used to modulate treatment duration and cessation.

Methods: MASTER was a multicentre, single-arm, phase 2 trial conducted in five academic medical centres in the USA.

Evaluation of a semi-automated approach for FDG PET image analysis for routine clinical application in patients with multiple myeloma.

Background: FDG PET/CT is a tool for assessing response to therapy in various cancers, and may provide an earlier biomarker of clinical response. We developed a novel semi-automated approach for analyzing FDG PET/CT images in patients with multiple myeloma (MM) to standardize FDG PET application.

Methods: Patients (n = 8) with relapsed/refractory MM from the Phase 2 study (NCT02899052) of venetoclax plus carfilzomib and dexamethasone underwent FDG PET/CT at baseline and up to two timepoints during treatment.

Teclistamab in patients with multiple myeloma and impaired renal function.

Robust anti-myeloma activity with teclistamab in patients with severe renal impairment.

Humoral immune reconstitution following therapy with daratumumab, carfilzomib, lenalidomide, and dexamethasone (Dara-KRd), autologous hematopoietic cell transplantation, and measurable residual disease-response-adapted treatment cessation.

Quadruplet induction, autologous hematopoietic cell transplant (AHCT), and measurable residual disease (MRD) response-adapted consolidation yield an unprecedented depth of response in newly diagnosed multiple myeloma. Patients treated on MASTER (NCT03224507) ceased therapy and entered active surveillance (MRD-SURE) after achieving MRD negativity. This study characterizes quantitative changes in the immunoglobulin (Ig) gene repertoire by next-generation sequencing and serum gamma globulin levels.

Utility of end of induction bone marrow biopsy and survival outcomes in acute promyelocytic leukemia treated with fixed-dose induction regimen.

Significant variations exist related to the end of induction practices in the management of Acute Promyelocytic Leukemia (APL). These variations include all-trans retinoic acid (ATRA)-arsenic trioxide (ATO) in fixed doses versus continuation until hematologic complete remission (CR) and performance versus omission of post-induction bone marrow biopsy to confirm morphological CR. A retrospective chart review was conducted of 61 patients (42 low/intermediate-risk and 19 high-risk) aged ≥ 18 years with newly diagnosed APL treated with fixed duration ATRA-ATO +/- cytoreduction at a tertiary medical center from December 2012 through March 2020.

Systemic Light Chain Amyloidosis, Version 2.2023, NCCN Clinical Practice Guidelines in Oncology.

Primary systemic light chain amyloidosis (SLCA) is characterized by production of light chains that get converted to amyloid fibrils with an affinity for visceral organs and causing organ dysfunction. The therapy for SLCA is directed to recovering the function of the affected organs by targeting the abnormal plasma cell clone and slowing deposition of amyloid fibrils. The NCCN Guidelines for SLCA provide recommendations for workup, diagnosis, and treatment of primary as well as previously treated SLCA.

Impact of autologous hematopoietic cell transplantation on disease burden quantified by next-generation sequencing in multiple myeloma treated with quadruplet therapy.

The incremental impact of autologous hematopoietic cell transplantation (AHCT) on disease burden with quadruplet induction in newly diagnosed multiple myeloma (NDDM) can be reappraised with the serial assessment of minimal residual disease (MRD). We describe the impact of AHCT on MM burden assessed by next-generation sequencing (NGS) for patients enrolled in a clinical trial utilizing quadruplet induction, AHCT, followed by MRD-adapted consolidation. We describe quantitative changes in MRD burden with AHCT and explore patient and disease features influencing the magnitude of MRD reduction with AHCT.

Tumor lysis syndrome and infectious complications during treatment with venetoclax combined with azacitidine or decitabine in patients with acute myeloid leukemia.

Venetoclax (Ven) in combination with azacitidine or decitabine (hypomethylating agent; HMA) is the standard-of-care treatment for older (≥75 years) or intensive chemotherapy ineligible adults with newly diagnosed acute myeloid leukemia (AML). Tumor lysis syndrome (TLS) and infectious complications are two of the most concerning associated adverse events. We studied the real-world incidence and outcomes of these adverse events with HMA/Ven in AML patients.

Revisiting the impact of immunoglobulin isotypes in multiple myeloma.

Association of immunoglobulin isotypes with survival in the context of modern prognostic factors has not been determined. We utilized the Flatiron Health Electronic Health Record database and identified 8468 MM patients. Compared to IgG MM, patients with IgA MM were more likely to have ISS-III, anemia, and t(4;14), and light chain (LC) MM had higher renal dysfunction and t(11;14).
