The outcomes of newly diagnosed elderly multiple myeloma patients treated at a single U.S. institution.

ABSTRACT: Improvements in the outcomes of elderly multiple myeloma (MM) patients have lagged behind those of transplant-eligible patients, likely due in part to the use of less efficacious melphalan-containing regimens. To date, there are very limited data for the outcomes of elderly MM patients in the United States (US), particularly for novel agent-containing triplet regimens. In this retrospective study at a single U.S. institution, the outcomes of 117 consecutive newly diagnosed, symptomatic MM patients over the age of 70 were evaluated. The median age was 75 years (range 70-95) with significant baseline comorbidities including 36% cardiac and 20% renal (CrCl < 30 mL/min). The median follow-up was 43 months and the median number of lines of therapy during the study period was 2 (1-7). Eighty-six patients (83%) received non-melphalan doublet, triplet, or quadruplet initial therapy, most with significant planned dose attenuations. For those treated with dose-attenuated RVD (n = 34), the outcomes were particularly impressive with overall response rate (ORR), complete remission and very good partial remission (CR + VGPR), and progression-free survival (PFS) of 94%, 65%, and 36 months, respectively, and overall survival (OS) not reached. The PFS with RVD was significantly greater than that of all other regimens (P = 0.030), including RD.

Chromosome 1 abnormalities in elderly patients with newly diagnosed multiple myeloma treated with novel therapies.

Project description:Multiple myeloma is a plasma cell disorder characterized by malignant plasma cell infiltration in the bone marrow, serum and/or urine monoclonal protein and organ damage. The aim of this study was to investigate the impact of chromosome 1 abnormalities in a group of elderly patients (>65 years) with newly diagnosed multiple myeloma enrolled in the GIMEMA-MM-03-05 trial and treated with bortezomib, melphalan and prednisone or bortezomib, melphalan, prednisone and thalidomide followed by bortezomib and thalidomide maintenance. We also evaluated the link between chromosome 1 abnormalities and other clinical, genetic and immunophenotypic features by a multivariate logistic regression model. Interphase fluorescence in situ hybridization on immunomagnetically purified plasma cells and bone marrow multiparameter flow cytometry were employed. A multivariate Cox model showed that chromosome 1 abnormalities, age >75 years and a CD19(+)/CD117(-) immunophenotype of bone marrow plasma cells were independent risk factors for overall survival in elderly patients with newly diagnosed multiple myeloma. Moreover, a detrimental effect of thalidomide, even when administered in association with bortezomib, was observed in patients with abnormal chromosome 1 as well as in those with 17p deletion, while the benefit of adding thalidomide to the bortezomib-melphalan-prednisone regimen was noted in patients carrying an aggressive CD19(+)/CD117(-) bone marrow plasma cell immunophenotype. This trial was registered at www.clinicaltri-als.gov as #NCT01063179.

Use of Bisphosphonates in Elderly Patients With Newly Diagnosed Multiple Myeloma.

Project description:Background: Bisphosphonates reduce skeletal-related events (SREs) in patients with multiple myeloma (MM) and, in some studies, improved survival. Since 2011, bisphosphonate use has been recommended by NCCN for all patients with newly diagnosed MM receiving antineoplastic therapy independent of the presence of bone disease. This study investigated their use after these guidelines were established. Methods: We identified patients aged ?65 years in the SEER-Medicare database with newly diagnosed MM between January 1, 2012, and December 31, 2013, who received antineoplastic therapy, had ?6 months of follow-up, and did not receive prior bisphosphonates. Presence of SREs at diagnosis was identified, including pathologic fracture, spinal cord compression, radiation to bone, or surgery to bone. Use of bisphosphonates was defined as having ?1 claim for an intravenous or oral bisphosphonate within 6 months after the start of antineoplastic therapy. We used multivariable modeling to compare users with nonusers, controlling for demographic and clinical covariates. We compared overall survival between users and nonusers using proportional hazards analysis. Results: Of 1,309 patients identified, 720 (55%) used a bisphosphonate. Factors associated with use included SRE at diagnosis (adjusted odds ratio [AOR], 2.60; 95% CI, 1.98-3.40), hypercalcemia (AOR, 1.74; 95% CI, 1.26-2.41), and use of proteasome inhibitor + immunomodulatory imide therapy (AOR, 1.70; 95% CI, 1.21-2.39). Chronic kidney disease (AOR, 0.48; 95% CI, 0.35-0.66) was associated with decreased use. Bisphosphonate use was associated with reduced mortality (hazard ratio, 0.70; 95% CI, 0.56-0.88). Conclusions: Although bisphosphonate use is recommended for all patients with newly diagnosed MM receiving antineoplastic therapy, 45% of patients in the United States did not receive this guideline-recommended care.

Hematopoietic score predicts outcomes in newly diagnosed multiple myeloma patients.

Project description:Risk stratification of multiple myeloma (MM) at diagnosis is critical. We examined the ability of hematopoietic indices including mean corpuscular volume (MCV), hemoglobin (Hgb), and platelet (Plt) to predict outcomes. This was a retrospective study of patients treated at Mayo Clinic between January 2004 and April 2018. We incorporated three variables (Hgb?<?10 g/dL, Plt?<?150?×?109 /L, and MCV?>?96?fL), assigning a score of 1 to each. We identified 1540 newly diagnosed MM patients, of whom 707 (46%) had a score of 0, 513 (33%) had a score of 1, 260 (17%) had a score of 2, and 60 (4%) had a score of 3. The score risk stratified patients into four groups with differing survivals. The median PFS was 32.3 months for score 0, 24.8 months for score 1, 21.7 months for score 2, and 18.3 months for score 3, for P <?.001. The median OS was 80.7 months for score 0, 59.9 months for score 1, 51.7 months for score 2, and 31.3 months for score 3, P <?.0001. Predictors of OS on the multivariable analysis were age???65 (HR, 1.93; P <?.0001), R-ISS stage (1-2 vs 3) (HR, 0.48; P <?.0001), and hematopoietic score (0-2 vs 3) (HR, 0.51; P =?.006). A hematopoietic score can predict survival in newly diagnosed myeloma patients.

Optimizing outcomes for patients with newly diagnosed multiple myeloma eligible for transplantation.

Project description:High-dose therapy with autologous stem cell transplantation (HDT-ASCT) has been considered to be the standard frontline treatment for younger, fit patients with multiple myeloma (MM) since the 1990s. Efforts continue to optimize the use of HDT-ASCT with the aim of improving outcomes. One strategy has been the incorporation of novel agents (thalidomide, lenalidomide and bortezomib) in the pre-transplantation setting as an induction therapy or in the post-transplantation setting as a consolidation or maintenance therapy. Given their high response rates, three-drug induction therapy regimens (for example, bortezomib-thalidomide-dexamethasone, lenalidomide-bortezomib-dexamethasone and cyclophosphamide-bortezomib-dexamethasone) are now the standard of care. Thalidomide and bortezomib are well suited for consolidation therapy, and regimens using these agents can improve the depth of response following HDT-ASCT. Lenalidomide is particularly well suited for long-term maintenance therapy following HDT-ASCT, and initial results are promising and have shown improvements in disease outcomes such as progression-free survival and overall survival in some cases, although a low incidence of second primary malignancies have been observed. Further studies are needed to determine the optimal regimen and duration of induction therapy, the impact of maintenance on overall survival and the safety of long-term treatment. Many of the studies currently underway in MM will help address these aspects.

Expression data of newly diagnosed multiple myeloma and extramedullary myeloma

Project description:Despite the development of novel therapeutic agents, multiple myeloma (MM) remains incurable, owing mainly to inevitable relapse in almost all patients. Some relapses occur as extramedullary disease (EMD), which is rare but is the most aggressive event in MM patients. Extramedullary myeloma (EMM) has extraordinary heterogeneous biological and clinical features. Previous studies have shown that expression levels of LncRNAs and mRNAs in different stages of MM are different. This study analyzes the expression levels of LncRNAs and mRNAs in primary plasma cells (PCs) from MM and EMM patients.

Daratumumab in untreated newly diagnosed multiple myeloma.

Project description:The treatment of multiple myeloma has evolved markedly in the last decade, but mortality remains high, emphasizing the need for more effective therapies. Daratumumab, a fully human monoclonal antibody targeting CD38, has shown clinical efficacy in relapsed/refractory multiple myeloma both as monotherapy and in combination with other drugs, including novel agents. More recently, promising results have been reported in patients with untreated newly diagnosed multiple myeloma (NDMM). Clinical trials thus far have shown enhanced efficacy and tolerability of several daratumumab-based combinations in both transplant ineligible and eligible patients, without compromising transplant ability. However, benefit in high-risk subpopulations is still unclear. A subcutaneous formulation of daratumumab has been introduced to decrease the risk of infusion reactions, with preliminary results showing non-inferior efficacy. The antimyeloma activity of daratumumab is achieved through multiple mechanisms including direct, Fc-dependent, and immunomodulatory mechanisms. Enhanced efficacy of daratumumab in combination with immunomodulatory drugs and proteasome inhibitors is supported by preclinical data showing synergism. This review will focus on the role of daratumumab in untreated NDMM patients, highlighting the results of major clinical trials, and listing ongoing trials that are evaluating various daratumumab-based combinations in this setting.

Copy number signatures predict chromothripsis and clinical outcomes in newly diagnosed multiple myeloma.

Project description:Chromothripsis is detectable in 20-30% of newly diagnosed multiple myeloma (NDMM) patients and is emerging as a new independent adverse prognostic factor. In this study we interrogate 752 NDMM patients using whole genome sequencing (WGS) to investigate the relationship of copy number (CN) signatures to chromothripsis and show they are highly associated. CN signatures are highly predictive of the presence of chromothripsis (AUC = 0.90) and can be used identify its adverse prognostic impact. The ability of CN signatures to predict the presence of chromothripsis is confirmed in a validation series of WGS comprised of 235 hematological cancers (AUC = 0.97) and an independent series of 34 NDMM (AUC = 0.87). We show that CN signatures can also be derived from whole exome data (WES) and using 677 cases from the same series of NDMM, we are able to predict both the presence of chromothripsis (AUC = 0.82) and its adverse prognostic impact. CN signatures constitute a flexible tool to identify the presence of chromothripsis and is applicable to WES and WGS data.
