OBJECTIVES: Decision-aids (DAs) may facilitate shared decision-making for patients and caregivers, by providing evidence-based information to assist healthcare professionals, patients, and caregivers in making choices about aspects of care, and/or highlighting decision factors to discuss with the potential of altering the treatment decision. These decision factors may not be well integrated in DAs. METHODS: A systematic literature review was conducted in the field of multiple myeloma (MM) on peer-reviewed publications, extended with a gray literature search. Data on whether and how patient and caregiver experience elements, other than survival and physical quality of life, were mentioned as decision factors in the identified MM DAs were extracted and analyzed qualitatively. RESULTS: Seventy MM DAs were found and analyzed; 51% of DAs mentioned any patient non-routinely assessed experience decision factors and only 17% mentioned any caregiver-related information. One hundred and forty potential decision factors were extracted, deduplicated and categorized into the following categories: 1) financial, 2) mode of administration / transportation issues, 3) personal beliefs and values, 4) emotional and social quality of life, 5) other medical information, 6) availability of social support, 7) caregiver burden. None of the DAs presented a comprehensive framework on all seven categories of decision factors being consider when mapping patient and caregiver experience value elements in MM. CONCLUSIONS: Based on available DAs, we recommend a set of patient and caregiver experience decision factors that have the potential to affect treatment choices of patients with MM, which should be included in DAs, including MM clinical guidelines.

AIMS: The goal of this study was to review the economic evaluations of health technologies in multiple myeloma (MM) and provide guidance and recommendations for future health economic analyses. MATERIALS AND METHODS: A systemic literature review (SLR) was conducted on original economic assessment studies and structured review papers focusing on the studies in MM. The search was limited to English language papers published from 1 January 2000 onwards. Publications not applying any type of modelling methodology to describe disease progression and patient pathways over a specific time horizon were excluded. RESULTS: A total of 2,643 publications were initially identified, of which 148 were eligible to be included in the full-text review phase. From these, 49 publications were included in the final analysis. Most published health economic analyses supported by models came from high-income countries. Evaluations from middle-income countries were rarely published. Diagnostic technologies were rarely modelled and integrated care had not been modelled. Very few models investigated MM treatments from a societal perspective and there was a relative lack of evaluations regarding minimal residual disease (MRD). LIMITATIONS: Limitations of the publications included differences between trial populations and modelled populations, justification of methods, lack of confounder analyses, and small trial populations. Limitations of our study included the infeasibility of comparing MM economic evaluations due to the significant variance in modelled therapeutic lines and indications, and the relative scarcity of published economic evaluations from non-high-income countries. CONCLUSIONS: As published economic models lacked many of the elements of the complex and heterogeneous patient pathways in MM and they focused on single decision problems, a thorough, open-source economic whole disease modelling framework is needed to assess the economic value of a wide range of technologies across countries with various income levels with a more detailed view on MM, by including patient-centric and societal aspects.

AIM: The goal of this research was to quantify and qualify all the costs associated with multiple myeloma (MM) from a healthcare and societal perspective and to highlight certain costs that are often underestimated. MATERIALS AND METHODS: The study used a mixed methods approach that consisted of three phases: a systemic literature review (SLR), a virtual roundtable discussion based on the results of the SLR, and an online survey. RESULTS: In total, 4321 records were identified by literature and snowball searches. After applying the eligibility criteria, 49 articles were included in the narrative summary. As combination treatments have become the mainstay of MM treatment, drug costs have become the most important component of the total healthcare costs. Collected evidence suggests that optimizing treatment pathways, besides prolonging patient survival and maintaining quality of life, has the potential to generate cost savings for all stakeholders (payers and patients). Improved patient access to new therapies that can improve outcomes may reduce the "financial toxicity" of MM by decreasing patients' and caregivers' productivity loss due to better prognosis and it also has the potential of reducing patients' direct health care payments. LIMITATIONS: Heterogeneity of research objectives of included studies, costing methods, and applied measurement units limited the comparability of cost data between studies. Data for more than half of the world's population, including China, Russia, the Middle East, and Africa were not investigated. CONCLUSION: While treatment costs are burdensome for healthcare systems, it is only one of several items that make up the True Cost of MM. Understanding these burdens is one way to argue for optimized treatment pathways and improve patient outcomes by tearing down access barriers.

Background: Multiple myeloma (MM), an incurable plasma cell malignancy, has a relative 5-year overall survival (OS) of 48.5% for newly diagnosed patients. Prospective real-world data reveals that 23% of transplant eligible MM patients relapse within 12 months of starting first-line bortezomib based therapy with a median OS of only 16.8 months (high-risk - HR). Genomic studies for these HR patients could inform rational secondary therapeutic options and prolong survival. Bone marrow (BM) genomic analysis in MM has methodological and conceptual shortcomings owing to the spatially and genomically heterogeneous nature of MM that can be largely overcome with circulating tumour DNA (ctDNA) analysis. Objective: To determine whether ctDNA analysis can define the mutational spectrum of patients with HR MM. Design: Phase II, multicentre single arm study of carfilzomib-thalidomide-dexamethasone (KTd) in 50 transplant-eligible newly diagnosed MM patients from September 2016 to April 2018 (Australasian Leukaemia and Lymphoma Group (ALLG) - MM17 trial) who were refractory (REF) to or demonstrated a suboptimal response (SOR) to bortezomib-based induction therapy. A total of 186 peripheral blood plasma and BM samples were obtained at baseline, at Cycle 3 day 1 (C3D1), end of the study (EOS) and/or at relapse. Somatic variants were identified with an ultra-sensitive targeted amplicon sequencing (TAS) assay incorporating 22-genes known to be mutated in MM. The mutational spectrum was correlated with progression-free survival (PFS) and OS. Results: TAS of 31 BM samples and 48 ctDNA samples revealed that in BM, KRAS mutations were detected in 42% of patients followed by ATR in 29% while in ctDNA, ATR mutations were prominent (36%), followed by FGFR3 and ATM (27% and 26.8%). We compared the ctDNA mutational spectrum at baseline between non-relapse and relapse patients on KTd and identified a significant difference in the proportion of patients with specific mutations - RAS/RAF: 3% vs 25%; ATM/ATR/TP53: 17% vs 41%, respectively (p Conclusions: Our results demonstrate that RAS/RAF and ATM/ATR/TP53 mutations in ctDNA are prognostic biomarkers of outcome to secondary salvage therapy in HR patients thus enabling design of targeted therapeutic approaches to improve survival.

Summary On the 14th June 2001, The Royal Marsden Hospital, London, hosted an unusual event, an international grand round, aimed at exploring a new concept in the treatment of multiple myeloma - operational cure. The speakers were Jean-Luc Harousseau (France), Gregory Mundy (USA), Brian Durie (USA) and Ray Powles (UK). Case histories were presented by Bhawna Sirohi (UK). The 80 invited guests included oncologists, radiotherapists, histopathologists, representatives of the International Myeloma Foundation, members of the press, and several myeloma patients, including the two whose case histories are presented below.

In contrast to the upfront setting in which the role of high-dose therapy with autologous hematopoietic cell transplantation (HCT) as consolidation of a first remission in patients with multiple myeloma (MM) is well established, the role of high-dose therapy with autologous or allogeneic HCT has not been extensively studied in MM patients relapsing after primary therapy. The International Myeloma Working Group together with the Blood and Marrow Transplant Clinical Trials Network, the American Society of Blood and Marrow Transplantation, and the European Society of Blood and Marrow Transplantation convened a meeting of MM experts to: (1) summarize current knowledge regarding the role of autologous or allogeneic HCT in MM patients progressing after primary therapy, (2) propose guidelines for the use of salvage HCT in MM, (3) identify knowledge gaps, (4) propose a research agenda, and (5) develop a collaborative initiative to move the research agenda forward. After reviewing the available data, the expert committee came to the following consensus statement for salvage autologous HCT: (1) In transplantation-eligible patients relapsing after primary therapy that did NOT include an autologous HCT, high-dose therapy with HCT as part of salvage therapy should be considered standard; (2) High-dose therapy and autologous HCT should be considered appropriate therapy for any patients relapsing after primary therapy that includes an autologous HCT with initial remission duration of more than 18 months; (3) High-dose therapy and autologous HCT can be used as a bridging strategy to allogeneic HCT; (4) The role of postsalvage HCT maintenance needs to be explored in the context of well-designed prospective trials that should include new agents, such as monoclonal antibodies, immune-modulating agents, and oral proteasome inhibitors; (5) Autologous Ha consolidation should be explored as a strategy to develop novel conditioning regimens or post-HCT strategies in patients with short (less than 18 months remissions) after primary therapy; and (6) Prospective randomized trials need to be performed to define the role of salvage autologous HCT in patients with MM relapsing after primary therapy comparing it to "best non-HCT therapy. The expert committee also underscored the importance of collecting enough hematopoietic stem cells to perform 2 transplantations early in the course of the disease. Regarding allogeneic Ha, the expert committee agreed on the following consensus statements: (1) Allogeneic HCT should be considered appropriate therapy for any eligible patient with early relapse (less than 24 months) after primary therapy that included an autologous HCT and/or high-risk features (ie, cytogenetics, extramedullary disease, plasma cell leukemia, or high lactate dehydrogenase); (2) Allogeneic HCT should be performed in the context of a clinical trial if possible; (3) The role of postallogeneic Ha maintenance therapy needs to be explored in the context of well-designed prospective trials; and (4) Prospective randomized trials need to be performed to define the role salvage allogeneic HCT in patients with MM relapsing after primary therapy.
