Abstract
OBJECTIVE Plant homeodomain finger protein 19 (PHF19) regulates hematopoietic stem cell differentiation and promotes multiple myeloma (MM) progression. This study intended to explore the potency of PHF19 at baseline and post induction treatment in estimating treatment response to protease inhibitors and survival in MM patients. METHODS This retrospective study screened 69 MM patients who received protease inhibitors with bone marrow (BM) samples available at both baseline and post induction treatment. Twenty healthy BM donors were included as healthy controls (HCs). PHF19 in plasma cells from BM was quantified by reverse transcription-quantitative polymerase chain reaction. RESULTS PHF19 at baseline and post induction treatment in MM patients were increased than in HCs. In MM patients, PHF19 was declined post induction treatment. Elevated PHF19 at baseline and post induction treatment were correlated with renal impairment, beta-2-microglobulin ≥5.5 mg/L, t (4; 14), higher international staging system (ISS) stage, and higher revised ISS (R-ISS) stage. Concerning treatment response, PHF19 at baseline and post induction treatment were negatively associated with complete response and overall response rate. Notably, abnormal PHF19 (above 95% quantile value of PHF19 in HCs) at baseline and post induction treatment were linked with shortened event-free survival (EFS) and overall survival (OS). After adjustment, abnormal PHF19 post induction treatment was independently related to shortened EFS (hazard ratio = 2.474) and OS (hazard ratio = 3.124). CONCLUSION PHF19 is aberrantly high and declines post induction therapy, which simultaneously reflects unfavorable treatment response to protease inhibitors as well as shorter EFS and OS in MM patients.

Abstract
Multiple myeloma management requires a balance between maximizing survival, minimizing adverse events to therapy, and monitoring disease progression. While previous work has proposed data-driven models for individual tasks, these approaches fail to provide a holistic view of a patient's disease state, limiting their utility to assist physician decision-making. To address this limitation, we developed a transformer-based machine learning model that jointly (1) predicts progression-free survival (PFS), overall survival (OS), and adverse events (AE), (2) forecasts key disease biomarkers, and (3) assesses the effect of different treatment strategies, e.g., ixazomib, lenalidomide, dexamethasone (IRd) vs lenalidomide, dexamethasone (Rd). Using TOURMALINE trial data, we trained and internally validated our model on newly diagnosed myeloma patients (N = 703) and externally validated it on relapsed and refractory myeloma patients (N = 720). Our model achieved superior performance to a risk model based on the multiple myeloma international staging system (ISS) (p < 0.001, Bonferroni corrected) and comparable performance to survival models trained separately on each task, but unable to forecast biomarkers. Our approach outperformed state-of-the-art deep learning models, tailored towards forecasting, on predicting key disease biomarkers (p < 0.001, Bonferroni corrected). Finally, leveraging our model's capacity to estimate individual-level treatment effects, we found that patients with IgA kappa myeloma appear to benefit the most from IRd. Our study suggests that a holistic assessment of a patient's myeloma course is possible, potentially serving as the foundation for a personalized decision support system.

Abstract
Multi-agent regimens incorporating immunomodulatory (IMiD®) agents such as thalidomide, lenalidomide, and pomalidomide have become the preferred standard of care for the treatment of patients with multiple myeloma (MM), resulting in improved survival outcomes. Currently, there are three IMiD agents approved for the treatment of MM: thalidomide, lenalidomide, and pomalidomide. Lenalidomide is commonly used to treat patients with newly diagnosed MM and as maintenance therapy following stem cell transplant or after disease relapse. Pomalidomide, the focus of this review, is approved in patients with relapsed/refractory MM (RRMM). Despite survival benefits, IMiD agents each have different safety profiles requiring consideration both prior to starting therapy and during treatment. Adverse event (AE) management is essential, not only to ensure treatment adherence and thus ensure optimal efficacy but also to maintain patient quality of life. Here, we discuss AEs associated with pomalidomide and present five clinically relevant hypothetical case studies in patients with RRMM to provide scenario-driven guidance regarding treatment selection and AE prevention and management in the clinical setting. Lastly, as new treatment approaches continue to be explored in MM, we also discuss novel cereblon E3 ligase modulator (CELMoD™) agents including iberdomide (CC-220) and mezigdomide (CC-92480).

Abstract
OBJECTIVE Circular RNA_0007841 (Circ_0007841) facilitates multiple myeloma (MM) progression and resistance of the bortezomib by experimental studies, while its clinical implication in MM patients is still unclear. This study intended to evaluate the longitudinal change and prognostic role of circ_0007841 expression in MM patients receiving bortezomib-based induction therapy. METHODS In this prospective study, bone marrow plasma cell (BMPC) samples were gained from 97 MM patients at diagnosis and after bortezomib-based induction therapy, and from 30 healthy controls (HCs) proposing BM donation. Then, circ_0007841 expression in BMPC samples was measured by reverse transcription-quantitative polymerase chain reaction. Additionally, MM patients were followed up for a median of 29.4 months. RESULTS Circ_0007841 expression was increased in MM patients compared to HCs (P < 0.001), but it was decreased after bortezomib-based induction therapy in MM patients (P < 0.001). Moreover, circ_0007841 expression at diagnosis was associated with the presence of t (4; 14) (P = 0.034), while its expression after bortezomib-based induction therapy was linked with higher revised international staging system stage (P = 0.025) in MM patients. Interestingly, circ_0007841 expression after bortezomib-based induction therapy was lower in MM patients who achieved complete remissions (P = 0.001) and overall responses (P = 0.002) compared to those who did not. Prognostically, circ_0007841 expression after bortezomib-based induction therapy (over the median vs. below the median) independently predicted shorter progression-free survival (hazard ratio (HR): 2.497, P = 0.002) and overall survival (HR: 3.107, P = 0.008) in MM patients. CONCLUSION Circ_0007841 quantification during induction therapy may reflect the response and survival benefits to bortezomib-based regimen in MM patients.

Abstract
Monoclonal gammopathy is a spectrum of disorders characterised by clonal proliferation of plasma cells or lymphocytes, which produce abnormal immunoglobulin or its components (monoclonal proteins). Monoclonal gammopathies are often categorised as low-tumour-burden diseases (eg, amyloid light chain (AL) amyloidosis), premalignant disorders (such as monoclonal gammopathy of undetermined significance and smouldering multiple myeloma), and malignancies (eg, multiple myeloma and Waldenström's macroglobulinaemia). Such diversity of concentration and structure makes monoclonal protein a challenging clonal marker. This article provides an overview on initial laboratory testing of monoclonal gammopathy to guide clinicians and laboratory professionals in the selection and interpretation of appropriate investigations.

Abstract
Background The nonrandom recurrence of chromosomal abnormalities in multiple myeloma (MM) raises the possibility that they play a role in the pathophysiology and development of the disease. Fluorescence in situ hybridization (FISH) can identify a high frequency of certain abnormalities without the need for the proliferative and infiltrative index of malignant plasma cells required for conventional cytogenetic analysis. In this study, we describe the association between clinico-biological characteristics and chromosomal abnormalities in 30 Moroccan patients. Methods The analysis of cytogenetic data, conventional and molecular, of 30 cases of MM, obtained from our previously cytogenetic study, and correlation of the results with the clinico-biological data of these patients. Results The bone marrow of 5 of 21 patients (23 %) contained a chromosomally abnormal clone, and all karyotypes were complicated (>3 abnormalities). Interphase FISH (iFISH) has detected aberrations in 14 out of 30 (46 %) of the total cases. The proportion of plasma cells in the bone marrow was higher in patients with chromosomal abnormalities (median 29 %) (p = 0.01917) than in patients without abnormalities (median 11 %). Although there was a difference in the median ß-2 microglobulin percentage (13.8 % versus 6.8 %), it was not statistically significant (p = 0.6818). We also, categorized patients into those with a complex clone and those with a sole abnormality. Patients with high bone marrow plasma cell rate (median 45 %) and high rate of ß-2 microglobulin (median 24 %) showed a complex karyotype and a higher iFISH detection rate than those with plasma cells count for (median 20 %) and ß-2 microglobulin count for (median 11 %) but without statistical significance (p = 0.4338 et p = 0.45 respectively). Furthermore, patients with aberrations had significantly shorter overall survival (100 % for 800 days versus 150 days only). Conclusion Our research has shown that different subgroups of patients with MM can be classified based on the underlying genetic abnormalities. Chromosomal abnormalities (CA) may give the plasma cell a proliferative advantage, increasing the virulence of the disease and affecting overall survival.

Post-infusion Costs Associated with Idecabtagene Vicleucel Treatment for Patients with Relapsed/Refractory Multiple Myeloma in the KarMMa Trial. Adv Ther 2023; 40:4626-4638. [PMID: 37597153 PMCID: PMC10499666 DOI: 10.1007/s12325-023-02623-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Accepted: 07/19/2023] [Indexed: 08/21/2023]
Abstract
INTRODUCTION Patients with triple-class exposed relapsed/refractory multiple myeloma (RRMM) have poor outcomes with substantial healthcare costs. Idecabtagene vicleucel (ide-cel), a B-cell maturation antigen (BCMA)-directed chimeric antigen receptor (CAR) T cell therapy, showed deep, durable responses in patients with RRMM in the pivotal phase 2 KarMMa trial (NCT03361748). Healthcare resource utilization (HCRU) and costs were estimated for ide-cel-treated patients in the KarMMa trial. METHODS Post-infusion costs were estimated based on HCRU data, including facility care, diagnostics, medications, and procedures. Length of stay (LOS) was extracted for inpatient and intensive care unit (ICU) care. All patients had a 14-day post-infusion inpatient stay per trial protocol. Analyses were conducted for patients treated in the United States (US), who received the ide-cel target dose of 450 × 106 CAR + T cells and assuming a 7-day inpatient stay. RESULTS Overall, 128 patients received ide-cel and were included in this analysis. Mean age was 60 years, 59% were men, and 81% were white. Mean total LOS was 23.9 days. Total estimated costs over 24 months post-infusion were US$115,614 per patient, driven by facility costs (75%; $86,385). Most costs were incurred in the first month (58%; $67,259). The scenario analysis assuming a 7-day inpatient stay showed estimated 24-month costs of $92,294. For the 54 (42%) patients who received ide-cel high dose, total costs over 24 months were $113,298 per patient. CONCLUSIONS Extrapolation of costs based on HCRU data from patients receiving single-infusion of ide-cel in the KarMMa trial showed substantially reduced HCRU and costs over 2 years after initial treatment. Most costs were incurred during the first month after ide-cel infusion, likely attributable to the 14-day inpatient stay required by the trial protocol. These findings suggest a nominal, incremental monthly cost of care immediately after treatment, which may be lower in routine clinical practice.

Abstract
BACKGROUND Serum free light chain (sFLC) assays are interpreted using a sFLC-ratio-based reference interval (manufacturer's interval) that was defined using a cohort of healthy patients. However, renal impairment elevates the sFLC-ratio, leading to a high false positive rate when using the manufacturer's interval. Prior studies have developed renal-specific reference intervals; however, this approach has not been widely adopted due to practical limitations. Thus, there remains a critical need for a renally robust sFLC interpretation method. METHODS Retrospective data mining was used to define patient cohorts that reflect the spectrum of renal function seen in clinical practice. Two new reference intervals, one based on the sFLC-ratio and one based on a novel principal component analysis (PCA)-based metric, were developed for the FREELITE assay (Binding Site) on the Roche Cobas c501 instrument (Roche). RESULTS Compared to the manufacturer's reference interval, both new methods exhibited significantly lower false positive rates and greater robustness to renal function while maintaining equivalent sensitivity for monoclonal gammopathy (MG) diagnosis. While not significantly different, the point estimate for sensitivity was highest for the PCA-based approach. CONCLUSION Renally robust sFLC interpretation using a single reference interval is possible given a reference cohort that reflects the variation in renal function observed in practice. Further studies are needed to achieve sufficient power and determine if the novel PCA-based metric offers superior sensitivity for MG diagnosis. These new methods offer the practical advantages of not requiring an estimated glomerular filtration rate result or multiple reference intervals, thereby lowering practical barriers to implementation.

Abstract
Objective. Multiple myeloma (MM) represents a malignant tumor with abnormal proliferation of plasma cells. The current study sought to investigate the changes in serum lncRNA MIR17HG (long noncoding RNA miR-17-92a-1 cluster host gene) levels in MM patients and its values in assessing the accuracy of MM diagnosis and predicting diagnosis. Methods. First, 108MM patients and 85 healthy controls were enrolled as the study subjects. The serum levels of MIR17HG in all subjects were determined by RT-qPCR. MM patients were clinically staged according to the Durie-Salmon (DS) and international staging system (ISS), and the levels of serum MIR17HG were compared among patients at different stages. The correlation of serum MIR17H level with serum creatinine (Scr), lactate dehydrogenase (LDH), and albumin (ALB) was analyzed using the Pearson method. The accuracy of the serum MIR17HG level in identifying MM was evaluated using receiver operating characteristic curves. The progression-free survival (PFS) and overall survival (OS) curves of MM patients were plotted using the Kaplan–Meier method. Results. Serum MIR17HG levels were up-regulated in MM patients and elevated with the development of DS and ISS stages. The serum MIR17HG was positively correlated with Scr and LDH and negatively correlated with ALB in MM patients. Serum MIR17HG level >1.485 could evaluate the accuracy of identifying MM. The PFS and OS were significantly shortened in MM patients with elevated MIR17HG levels. Conclusion. Our findings collectively indicate that the serum MIR17HG can aid the evaluation of accurate MM identification, and a high serum MIR17HG level can predict poor prognosis of patients with MM.

Phase I study of plitidepsin in combination with bortezomib and dexamethasone in patients with relapsed/refractory multiple myeloma. Cancer Med 2023; 12:3999-4009. [PMID: 36127823 PMCID: PMC9972151 DOI: 10.1002/cam4.5250] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 06/23/2022] [Accepted: 08/02/2022] [Indexed: 11/10/2022] Open
Abstract
Previous studies showed antitumor activity for plitidepsin plus dexamethasone (DXM) in relapsed/refractory multiple myeloma (r/r MM), and in vitro synergism with bortezomib (BTZ) or DXM against MM cells. This phase I trial evaluated plitidepsin (3-h intravenous infusion Day 1 and 15), BTZ (subcutaneous bolus Day 1, 4, 8, and 11), and DXM (orally Day 1, 8, 15, and 22), every 4 weeks in 36 r/r MM patients. Twenty-two patients were treated using a standard dose escalation design (10 at the recommended dose [RD] cohort), and 14 additional patients were treated to expand the RD cohort. No dose-limiting toxicities (DLTs) occurred during dose escalation. The highest dose level evaluated (plitidepsin 5.0 mg/m2 , BTZ 1.3 mg/m2 , DXM 40.0 mg) was the RD for phase II studies. Results shown herein are focused on this RD. Two patients had DLTs (grade 3 diarrhea, and grade 3 nausea/vomiting refractory to antiemetic therapy). Grade ≥ 3 hematological toxicity (thrombocytopenia 46%, anemia 33%, and neutropenia 17%) was manageable and did not result in treatment discontinuation. Transient and manageable grade 3 ALT increase (26%) was the most common biochemical abnormality. At the RD cohort, overall response rate was 22.2% (95%CI, 6.4%-47.6%), including one stringent complete response, one very good partial response, and two partial responses in r/r patients to BTZ and/or lenalidomide. The clinical benefit rate was 77.8% (95%CI, 52.4-93.6%). No major pharmacokinetic drug-drug interaction was found. In conclusion, the triple combination of plitidepsin, BTZ, and DXM showed an acceptable safety profile and had moderate activity in adult patients with r/r MM.

Abstract
Tandem ASCT has been suggested as a valid approach to improve the prognosis of patients with MM and HR cytogenetic. In this observational, retrospective study, 213 patients with newly diagnosed MM and HR cytogenetic in 35 hospitals from the Spanish Myeloma Group underwent single or tandem ASCT between January 2015 and December 2019 after induction with VTD/VRD. HR cytogenetic was defined as having ≥1 of the following: del17p, t(4;14), t(14;16) or gain 1q21. More patients in the tandem group had R-ISS 3 and >1 cytogenetic abnormality at diagnosis. With a median follow-up of 31 months (range, 10-82), PFS after single ASCT was 41 months versus 48 months with tandem ASCT (p = 0.33). PFS in patients with del17p undergoing single ASCT was 41 months, while 52% of patients undergoing tandem ASCT were alive and disease free at 48 months. In conclusion, tandem ASCT partly overcomes the bad prognosis of HR cytogenetic.

HEMATOLOGY (AMSTERDAM, NETHERLANDS) 2022; 27:1102-1109. [PMID: 36121128 DOI: 10.1080/16078454.2022.2117123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/04/2022]
Abstract
OBJECTIVE Spliced X-Box binding protein 1 (sXBP1) modulates malignant cell activities and enhances the bortezomib sensitivity in multiple myeloma (MM) cells, while its clinical value in MM patients remains elusive. Hence, the current study aimed to explore this issue, particularly the correlation of sXBP1 with treatment outcomes of bortezomib-based therapy in MM patients. METHODS Totally, 97 newly-diagnosed MM patients undergoing bortezomib-based therapy, 20 disease controls (DCs), and 20 health controls (HCs) were enrolled. Bone marrow plasma cell samples were acquired to determine sXBP1 by RT-qPCR. RESULTS sXBP1 was lowest in MM patients, followed by DCs, and highest in HCs (P < 0.001). Beyond that, sXBP1 discriminated MM patients from DCs with area under curve (AUC) of 0.728 (95% confidence interval (CI): 0.610-0.847) and HCs with AUC of 0.855 (95% CI: 0.771-0.939). sXBP1 was negatively associated with t (4; 14) (P = 0.047), Revised International Staging System stage (P = 0.008). There was a trend that sXBP1 was negatively correlated with β2-MG, LDH, and t (14; 16) (without statistical significance). sXBP1 was higher in patients with complete response (CR) compared to those with non-CR (P = 0.017) and higher in patients with objective response rate (ORR) compared to those with non-ORR (P = 0.006). sXBP1 (high vs. low) was linked with longer progression-free survival (PFS) (P = 0.011) and overall survival (P = 0.045) in MM patients. Additionally, sXBP1 (high vs. low) (P = 0.025) independently estimated a longer PFS. CONCLUSION sXBP1 forecasts a favorable treatment response and survival benefit toward bortezomib-based therapy in multiple myeloma patients.

Abstract
WHAT IS KNOWN AND OBJECTIVE NIMA related kinase 2 (NEK2) promotes the malignant transformation and enhances the chemoresistance to proteasome inhibitor in multiple myeloma (MM) cell lines. The current study aimed to further investigate its correlation with clinical features and responsiveness to bortezomib treatment in MM patients. METHODS Totally, 76 MM patients and 30 health donors (HDs) were enrolled to collect bone marrow plasma cells for NEK2 detection using reverse transcription quantitative polymerase chain reaction (RT-qPCR). Meanwhile, NEK2 siRNA was transfected into the RPMI-8226 and KMS-11 cells, subsequently their cell viability was evaluated using Cell Counting Kit-8 reagent after treatment with different doses of bortezomib. RESULTS AND DISCUSSION NEK2 expression was higher in MM patients compared with HDs (Z = -5.123, p < 0.001). Besides, elevated NEK2 expression was associated with the occurrence of the bone lesion (χ2 = 4.610, p = 0.032) and t (4; 14) (χ2 = 3.971, p = 0.046). Additionally, elevated NEK2 expression was correlated with declined objective response rate (ORR) (χ2 = 4.808, p = 0.028), but not with complete response (CR) (χ2 = 2.341, p = 0.126). More importantly, elevated NEK2 expression was correlated with shorter progression-free survival (PFS) (χ2 = 8.352, p = 0.039), but not with overall survival (OS) (χ2 = 5.624, p = 0.131), What is more, NEK2 silence decreased the cell viability under bortezomib treatment and the inhibitory concentration (IC50 ) value of bortezomib in RPMI-8226 and KMS-11 cell lines (all p < 0.05). WHAT IS NEW AND CONCLUSION NEK2 overexpression links with occurrence of bone lesion, t (4; 14), and poor prognosis to bortezomib treatment in MM patients.

Cross-Sectional and Longitudinal Associations Between the Serum G\lobulin Level, and Renal Impairment and All-Cause Deaths in Chinese Patients With Newly Diagnosed Multiple Myeloma.

Abstract
Background A large number of studies have shown that serum globulin plays an important role in a variety of cancers; However, few studies have identified the association between serum globulin levels and end-stage renal disease (ESRD) and all-cause death in Chinese patients with multiple myeloma (MM). Methods A generalized additive model and smooth curve fitting were fitted to assess the cross-sectional relationship between the serum globulin levels and renal impairment (RI) at baseline. Multivariate-adjusted Cox regression models were performed to determine the associations between the baseline serum globulin levels and the onset of all-cause death and ESRD in patients with MM. Results 288 participants who were followed for > 3 months were eligible for the retrospective study. The median serum globulin level was 5.1 ± 2.6 mg/dL. The average follow-up time was 23.3 months. Thirty-two patients (11.5%) had ESRD and 24 patients (8.33%) died after diagnosis. In patients with a serum globulin level < 6.1 mg/dL, the serum globulin level had an independent, negative correlation with the occurrence of MM-related RI. Patients were divided into three groups on the basis of serum globulin tertiles: low (L group), 3.3 mg/dL; middle (M group), 3.3-6.0 mg/dL; and high (H group), 6.0 mg/dL. Cox regression analysis showed that low serum globulin levels may be independent risk factors for all-cause death and the occurrence of ESRD in patients with MM; however, an elevated baseline serum globulin can predict all-cause deaths in patients with MM, but cannot predict the onset of ESRD. Conclusions This observational study suggested that there was a non-linear relationship between the serum globulin level and the occurrence of RI in patients with MM. This finding showed that the serum globulin level had a U-shaped association with all-cause death and an L-shaped association with ESRD in patients with MM.

Abstract
OBJECTIVE Long non-coding RNA ANGPTL1-3 (lnc-ANGPTL1-3) is previously observed to induce bortezomib resistance via targeting microRNA-30a (miR-30a) in multiple myeloma (MM). Hence, this study aimed to further explore the relationship between lnc-ANGPTL1-3 and miR-30a and their linkage with disease properties and prognosis in bortezomib-treated MM patients. METHODS Fifty-nine MM patients underwent treatment with the bortezomib-based regimen, and 30 healthy donors were consecutively enrolled. Bone marrow samples were collected from MM patients (before therapy) and healthy donors; then, plasma cells were separated for lnc-ANGPTL1-3 and miR-30a detection by RT-qPCR. Then treatment response, progression-free survival (PFS), and overall survival (OS) of MM patients were assessed. RESULTS Lnc-ANGPTL1-3 was upregulated while miR-30a was downregulated in MM patients compared to healthy donors (both P < 0.001), then a negative correlation between lnc-ANGPTL1-3 and miR-30a was found in MM patients (P < 0.001) instead of in health donors (P = 0.188). In MM patients, lnc-ANGPTL1-3 correlated with increased t (4;14) (P = 0.033), Del (17p) (P = 0.018), ISS stage (P = 0.020), R-ISS stage (P = 0.025) but not t (14;16) (P = 0.255) or Durie-Salmon stage (P = 0.186); while miR-30a only related to decreased t (14;16) (P = 0.025) and R-ISS stage (P = 0.006). Besides, lnc-ANGPTL1-3 predicted lower complete response (CR) (P = 0.034), poor PFS (P = 0.016) and OS (P = 0.041) but not objective response rate (ORR) (P = 0.128). However, miR-30a forecasted higher CR (P = 0.013), prolonged PFS (P = 0.014), and OS (P = 0.045) but not ORR (P = 0.407). CONCLUSION Lnc-ANGPTL1-3 negative correlates with miR-30a, which links with key cytogenetic features, ISS/R-ISS stage, and prognosis in MM patients who underwent treatment of bortezomib-based regimen.

Abstract
Purpose The interaction between tumor cells and tumor microenvironment (TME) has an important impact on progression and prognosis of multiple myeloma (MM), and has been proven to be promising therapeutic targets. This study intended to explore the relationship between TME and prognosis and identify valuable biomarkers of MM. Methods The transcriptomic and clinical information of MM retrieved from the Gene Expression Omnibus (GEO) were used to establish the model. The curve of Kaplan–Meier survival and the time-dependent receiver operating characteristic (ROC) were used to appraise the predictive ability. A nomogram was established for clinical application. Furthermore, the CIBERSORT algorithm was used to investigate the relation between IRGPI with the infiltration of immune cells. We also used histology, as well as in vitro and in vivo experiments to validate these findings. Results The results demonstrated an immune-related gene-based prognostic index (IRGPI) combined with clinical information. Patients were separated into high- and low-risk groups based on risk score, which had significantly difference in survival status and immune infiltrations. Furthermore, we identified CXCL11 as a key factor, which positively promotes the progression of MM and correlate with macrophage M2-like polarization and tumor immune cells infiltration. Conclusion Our findings suggest the IRGPI significantly demonstrate the differential prognosis and prediction of immune cells infiltration. It provides some insights into the complex interaction between myeloma tumor cells and the TME, as well as in the development of a novel biomarker target for anti-MM therapy.

Abstract
CONTEXT.— The process for identifying patients with monoclonal gammopathies is complex. Initial detection of a monoclonal immunoglobulin protein (M protein) in the serum or urine often requires compilation of analytical data from several areas of the laboratory. The detection of M proteins depends on adequacy of the sample provided, available clinical information, and the laboratory tests used. OBJECTIVE.— To develop an evidence-based guideline for the initial laboratory detection of M proteins. DESIGN.— To develop evidence-based recommendations, the College of American Pathologists convened a panel of experts in the diagnosis and treatment of monoclonal gammopathies and the laboratory procedures used for the initial detection of M proteins. The panel conducted a systematic literature review to address key questions. Using the Grading of Recommendations Assessment, Development, and Evaluation approach, recommendations were created based on the available evidence, strength of that evidence, and key judgements as defined in the Grading of Recommendations Assessment, Development, and Evaluation Evidence to Decision framework. RESULTS.— Nine guideline statements were established to optimize sample selection and testing for the initial detection and quantitative measurement of M proteins used to diagnose monoclonal gammopathies. CONCLUSIONS.— This guideline was constructed to harmonize and strengthen the initial detection of an M protein in patients displaying symptoms or laboratory features of a monoclonal gammopathy. It endorses more comprehensive initial testing when there is suspicion of amyloid light chain amyloidosis or neuropathies, such as POEMS (polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes) syndrome, associated with an M protein.

Abstract
OBJECTIVES Monoclonal immunoglobulins (M-proteins) that migrate in the β region on serum protein electrophoresis (SPEP) are often cloaked by this region's normal constituents. The present study interrogates the utility of using both quantitative and qualitative alterations in β-region bands for detection of β-migrating M-proteins. METHODS Consecutive SPEP cases analyzed by capillary electrophoresis were searched to identify the initial workup on 1,841 patients with increased total β regions, suspicious β-region findings resulting in reflex immunofixation (IFE), or immunosubtraction (ISUB). To augment quantitative information, separate β1 and β2 measurements were established and retrospectively used to evaluate their sensitivity for M-protein detection. RESULTS We identified M-proteins in 205 (11.1%) cases, including immunoglobulin A (IgA) (54%), IgG (24%), IgM (13%), and free light chain (9%) isotypes. Of the 15 cases flagged by separate β1 and β2 measurements that were not identified by total β-region measurement, 1 progressed to myeloma. Of the 56 β-migrating M-proteins identified by qualitative features but without increase in any of the β-region measurements, 1 progressed to myeloma. CONCLUSIONS A combination of separate measurements for β1 and β2 regions together with detection of β-region distortions increase sensitivity for identifying β-migrating M-proteins via reflex IFE or ISUB.

Abstract
INTRODUCTION Multiple Myeloma (MM) is hematological neoplasia originating from plasma cells, which accounts for almost 1% of all oncologic malignancies. The median age of patients at diagnosis is about 65 years old and over. In this age group, cardiovascular (CV) diseases often co-exist, increasing the risk of adverse events related to MM treatment. A comprehensive search on the main educational platforms was performed and high-quality original articles and reviews were included. AREAS COVERED Patients affected by MM are at risk for heart failure, uncontrolled systemic hypertension, accelerated ischemic heart disease, arterial/venous thromboembolism, and arrhythmias. These complications may be due to the effects of chemotherapy on the CV system, which may play on preexisting risk factors, and amyloid deposition at cardiac level. EXPERT OPINION This review provides an updated overview of the spectrum of CV diseases that may affect MM patients, highlighting possible treatment strategies according to the latest recommendations. Cooperation between onco-hematologist and cardiologist is crucial in managing this population, in particular for adequate risk assessment, early diagnosis of CV complications, and proper treatment.

Abstract
BACKGROUND Treatment options for patients with solitary plasmacytoma (SP) or multiple myeloma (MM) should be discussed in an interdisciplinary context. This systematic review focuses on the importance of radiotherapy in MM and SP. OBJECTIVE Summary of local radio-oncological treatment options for patients with SP and MM. MATERIALS AND METHODS Based on a systematic literature search, the current evidence on the topic was analyzed and summarized. RESULTS Patients with SP should be primarily treated with radiotherapy with or without surgery. Irradiation concepts may vary depending on risk factors and manifestation (solitary bone plasmacytoma vs. solitary extramedullary plasmacytoma). Although local control rates are high after radiotherapy, progression to multiple myeloma frequently occurs. In patients with MM, radiation is mainly used in palliative settings for pain relief, prevention of fractures or in patients who suffer from neurological symptoms due to spinal cord compression. Irradiation dose and fractionation should be selected based on treatment indication and general condition of the patient. CONCLUSION Although most patients receive systemic treatment at initial diagnosis, approximately 40% of patients with MM will require radiation during the course of their disease. While radiation is mainly used for palliation in patients with MM, it represents the primary and curative treatment option in patients with SP.

Abstract
BACKGROUND Long noncoding RNA PCAT1 (lnc-PCAT1) involves in the proliferation and drug sensitivity of multiple myeloma (MM), while its prognostic role in MM patients is still obscure. This study aimed to explore the association of lnc-PCAT1 with MM risk, clinical characteristics, treatment response, progression-free survival (PFS), and overall survival (OS). METHODS A total of 83 symptomatic MM patients were enrolled in this study. Additionally, 30 healthy bone marrow donors as health controls were also recruited. Bone marrow plasma cell samples of MM patients and health donors were collected. Lnc-PCAT1 in bone marrow plasma cells was detected by reverse transcription-quantitative polymerase chain reaction. RESULTS Lnc-PCAT1 was increased in MM patients than in health donors (p < 0.001), and receiver operating characteristic (ROC) curve showed that lnc-PCAT1 had excellent capability of discriminating MM patients from health donors (area under curve: 0.932, 95% confidence interval: 0.889-0.976). In MM patients, lnc-PCAT1 was correlated with bone lesion (p = 0.024), higher β2 -MG (p = 0.005), LDH (p = 0.037), and presence of Del (17p) (p = 0.029). Lnc-PCAT1 was also associated with poor ISS stage (p = 0.013) and R-ISS stage (p = 0.005). Besides, lnc-PCAT1 was reduced after treatment (p < 0.001); meanwhile, lnc-PCAT1 before treatment was correlated with lower CR (p = 0.046) but not ORR (p = 0.185). Additionally, lnc-PCAT1 after treatment was associated with lower CR (p = 0.003) and ORR (p = 0.010). Furthermore, baseline Inc-PCAT1 high and Inc-PCAT1 increase after treatment were correlated with worse PFS and OS (all p < 0.05). CONCLUSION Lnc-PCAT1 dysregulation serves as a biomarker for diagnosis and prognosis for MM.

Abstract
Multiple myeloma (MM) is the third most common haematological malignancy, with increasing prevalence over recent years. Advances in therapy have improved survival, changing the clinical course of MM into a chronic condition and meaning that management of comorbidities is fundamental to improve clinical outcomes. Cardiovascular (CV) events affect up to 7.5% of individuals with MM, due to a combination of patient, disease and treatment-related factors and adversely impact survival. MM typically affects older people, many with pre-existing CV risk factors or established CV disease, and the disease itself can cause renal impairment, anaemia and hyperviscosity, which exacerabate these further. Up to 15% of patients with MM develop systemic amyloidosis, with prognosis determined by the extent of cardiac involvement. Management of MM generally involves administration of multiple treatment lines over several years as disease progresses, with many drug classes associated with adverse CV effects including high rates of venous and arterial thrombosis alongside heart failure. Recommendations for holistic management of patients with MM now include routine baseline risk stratification including ECG and echocardiography and administration of thromboprophylaxis drugs for patients treated with immunomodulatory drugs. Close surveillance of high-risk patients with collaboration between haematology and cardiology is required, with prompt investigation in the event of CV symptoms, in order to identify and treat complications early. Decisions regarding discontinuation of cardiotoxic therapies should be made in a multidisciplinary setting, taking into account the severity of the complication, prognosis, expected benefits and the availability of effective alternatives.

Abstract
BACKGROUND Despite major therapeutic advances, the rational choice of the most appropriate first-line regimen in newly diagnosed transplant-ineligible multiple myeloma (TIE-MM) is currently undefined. AIM We aimed to identify the most effective first-line treatment for TIE-MM patients. METHODS A total of 37 articles, including 34 treatments and 16,681 patients, were included in this Bayesian network meta-analysis. The outcomes of interest were risk ratios (RR) for progression-free survival (PFS) and overall survival (OS). RESULTS Based on surface under cumulative ranking curve values, daratumumab-bortezomib-melphalan-prednisone (Dara-VMP) and daratumumab-lenalidomide-dexamethasone (Dara-Rd28) showed superiority compared to other combinations regarding 12-, 24-, 36-, and 48-month PFS. Dara-VMP also ranked first for 12-, 24-, 36-, and 48-month OS. CONCLUSION Our finding supports the incorporation of daratumumab into first-line regimens. Additionally, these results highlight the relative benefit of incorporating novel agents like monoclonal antibodies, immunomodulatory derivatives, and proteasome inhibitors in combination with the currently existing treatment options.

Abstract
Simple Summary Multiple myeloma (MM) patients with relapsing and/or refractory (RR) disease are exposed for a prolonged time to multiple drugs, which increase the risk of toxicity. In addition to tumor response, preserving the quality of life represents an important goal for this patient population. Therefore, supportive therapy plays a pivotal role in their treatment by limiting disease- and drug-related complications. The aim of this review is to outline current standards and future strategies to prevent and treat renal insufficiency, anemia, bone disease, and infection, including COVID-19, in RRMM patients. In addition, the incidence and treatment of side effects of novel anti-MM agents will be discussed. Abstract Relapsed/refractory (RR) multiple myeloma (MM) patients are a fragile population because of prolonged drug exposure and advanced age. Preserving a good quality of life is of high priority for these patients and the treatment of disease- and treatment-related complications plays a key role in their management. By preventing and limiting MM-induced complications, supportive care improves patients’ outcome. Erythropoietin-stimulating agents and bisphosphonates are well-established supportive strategies, yet novel agents are under investigation, such as anabolic bone agents and activin receptor-like kinase (ALK) inhibitors. The recent dramatic changes in the treatment landscape of MM pose an additional challenge for the routine care of RRMM patients. Multidrug combinations in first and later lines increase the risk for long-lasting toxicities, including adverse cardiovascular and neurological events. Moreover, recently approved first-in-class drugs have unique side-effect profiles, such as ocular toxicity of belantamab mafodotin or gastrointestinal toxicity of selinexor. This review discusses current standards in supportive treatment of RRMM patients, including recommendations in light of the recent SARS-CoV-19 pandemic, and critically looks at the incidence and management of side effects of standard as well as next generation anti-MM agents.

Abstract
Background The International Myeloma Working Group and College of American Pathologists recommend a 24-h urine collection to determine the Bence Jones protein (BJP) excretion level for monitoring treatment response in patients with multiple myeloma (MM). There are several issues related to sample collection and the method is prone to inaccuracy. Objective This study compared measured 24-h to random urine collections for the quantitation of BJP in a South African population. Methods Sixty-six patients with MM submitted random urine samples with their routine 24-h urine collection from April 2016 – March 2018. Measured 24-h urine BJP was compared to two estimated 24-h BJP excretions calculated as follows: Estimation 1 (E1): Estimated 24-h BJP (mg/24 h) = Urine BJP/Creatinine ratio (mg/mmol) × 10. Estimation 2 (E2): Estimated 24-h BJP (mg/24 h) = Urine BJP/Creatinine ratio (mg/mmol) × 15 mg/kg for women or × 20 mg/kg for men. Results Correlation of estimation equations E1 and E2 to the measured 24-h urine BJP was 0.893. Patients showed no difference in classification of treatment response using either the E1 or E2 estimation equations when compared to the measured 24-h urine BJP results. Conclusion This study demonstrates that the estimated 24-h BJP shows a high degree of correlation with the measured 24-h BJP and can likely be used to monitor treatment response in South African patients with MM.

Abstract
PURPOSE M-protein is a well-established biomarker used for multiple myeloma monitoring. Current improvements in multiple myeloma treatment created the need to monitor minimal residual disease (MRD) with high sensitivity. Measuring residual levels of M-protein in serum by MS was established as a sensitive assay for disease monitoring. In this study we evaluated the performance of EasyM-a noninvasive, sensitive, MS-based assay for M-protein monitoring. EXPERIMENTAL DESIGN Twenty-six patients enrolled in MCRN-001 clinical trial of two high-dose alkylating agents as conditioning followed by lenalidomide maintenance were selected for the study. All selected patients achieved complete responses (CR) during treatment, whereas five experienced progressive disease on study. The M-protein of each patient was first sequenced from the diagnostic serum using our de novo protein sequencing platform. The patient-specific M-protein peptides were then measured by targeted MS assay to monitor the response to treatment. RESULTS The M-protein doubling over 6 months measured by EasyM could predict the relapse in 4 of 5 relapsed patients 2 to 11 months earlier than conventional testing. In 21 disease-free patients, the M-protein was still detectable by EasyM despite normal FLC and MRD negativity. Importantly, of 72 MRD negative samples with CR status, 62 were positive by EasyM. The best sensitivity achieved by EasyM, detecting 0.58 mg/L of M-protein, was 1,000- and 200-fold higher compared with serum protein electrophoresis and immunofixation electrophoresis, respectively. CONCLUSIONS EasyM was demonstrated to be a noninvasive, sensitive assay with superior performance compared with other assays, making it ideal for multiple myeloma monitoring and relapse prediction.

Abstract
Multiple myeloma (MM) is a hematological malignancy caused by the clonal expansion of plasma cells. The incidence of MM worldwide is increasing with greater than 140 000 people being diagnosed with MM per year. Whereas 5-year survival after a diagnosis of MM has improved from 28% in 1975 to 56% in 2012, the disease remains essentially incurable. In this review, we summarize our current understanding of MM including its epidemiology, genetics and biology. We will also provide an overview of MM management that has led to improvements in survival, including recent changes to diagnosis and therapies. Areas of unmet need include the management of patients with high-risk MM, those with reduced performance status and those refractory to standard therapies. Ongoing research into the biology and early detection of MM as well as the development of novel therapies, such as immunotherapies, has the potential to influence MM practice in the future.

Abstract
OBJECTIVES The therapeutic monoclonal antibody (t-mAb) daratumumab, used to treat multiple myeloma (MM) patients, interferes with routine, electrophoretic based M-protein diagnostics. Electrophoretic response assessment becomes increasingly difficult when multiple t-mAbs are combined for use in a single patient. This is the first study to address the analytical challenges of M-protein monitoring when multiple t-mAbs are combined. METHODS In this proof-of-principle study we evaluate two different methods to monitor M-protein responses in three MM patients, who receive both daratumumab and nivolumab. The double hydrashift assay aims to resolve t-mAb interference on immunofixation. The MS-MRD (mass spectrometry minimal residual disease) assay measures clonotypic peptides to quantitate both M-protein and t-mAb concentrations. RESULTS After exposure to daratumumab and nivolumab, both t-mAbs become visible on immunofixation electrophoresis (IFE) as two IgG-kappa bands that migrate close to each other at the cathodal end of the γ-region. In case the M-protein co-migrates with these t-mAbs, the observed interference was completely abolished with the double IFE hydrashift assay. In all three patients the MS-MRD assay was also able to distinguish the M-protein from the t-mAbs. Additional advantage of the MS-MRD assay is that this multiplex assay is more sensitive and allows quantitative M-protein-, daratumumab- and nivolumab-monitoring. CONCLUSIONS Daratumumab and nivolumab interfere with electrophoretic M-protein diagnostics. However, the M-protein can be distinguished from both t-mAbs by use of a double hydrashift assay. The MS-MRD assay provides an alternative method that allows sensitive and simultaneous quantitative monitoring of both the M-protein and t-mAbs.

Abstract
BACKGROUND The concentration of monoclonal immunoglobulins (Igs) in neoplastic monoclonal gammopathic manifestations is generally measured by densitometric scanning of the monoclonal peaks on gel or by measuring absorbance at 210 nm in capillary electrophoresis (CE). For monoclonal Igs migrating in the beta region, measurement is complicated by the major beta-region proteins, namely, transferrin and C3. METHODS C3 interference in densitometry was eliminated by heat treatment of serum, and monoclonal Igs were quantified by densitometry of the residual band. The immunochemical measurement of transferrin was converted to its equivalent densitometric quantity. For monoclonal Ig migrating with transferrin, the contribution of the latter was removed by subtracting the converted transferrin concentration from the combined densitometric quantification of the band. With CE, monoclonal Ig was measured by using immunosubtraction (ISUB) to guide demarcation. RESULTS The results obtained using the C3 depletion and transferrin subtraction method were lower and yet comparable to the results derived from using CE measurement guided by ISUB. As we expected, the results from both methods were lower than those derived from a perpendicular drop measurement of the peak or via nephelometric assay of the involved isotype. DISCUSSION Accurate measurement of monoclonal Igs is important for the diagnosis and monitoring of monoclonal gammopathic manifestations. Determination of serum free light chain concentration per gram of monoclonal Ig is an essential measure for the diagnosis of light chain-predominant multiple myeloma. The method described herein improves accuracy of measurements for monoclonal Igs migrating in the beta region, without the need for special reagents or equipment.

Abstract
Cancerous inhibitor of protein phosphatase 2A (Cip2A) is an oncoprotein that promotes the development of several types of cancer. However, its molecular function in osteoblast differentiation remains unclear. In this study, we found that Cip2A was upregulated under osteogenic conditions in MG63 cells. Besides, overexpression of Cip2A significantly increased the expression of Runt-related transcription factor 2 (Runx2) and alkaline phosphatase (ALP). Inversely, the knockdown of Cip2A in MG63 cells suppressed osteoblast differentiation. Cip2A expression during osteogenic differentiation was mediated by extracellular signal-regulated kinase (ERK) activation. Taken together, our results suggest that Cip2A plays important role in regulating osteoblast differentiation by inducing ERK phosphorylation in MG63 cells.

Abstract
The aim of the study is to evaluate the effectiveness of short whole-body magnetic resonance imaging (WBMRI) protocols for the overall assessment of bone marrow involvement in patients with multiple myeloma (MM), in comparison with standard whole-body MRI protocol. Patients with biopsy-proven MM, who underwent a WBMRI with full-body coverage (from vertex to feet) were retrospectively enrolled. WBMRI images were independently evaluated by two expert radiologists, in terms of infiltration patterns (normal, focal, diffuse, and combined), according to location (the whole skeleton was divided into six anatomic districts: skull, spine, sternum and ribs, upper limbs, pelvis and proximal two-thirds of the femur, remaining parts of lower limbs) and lytic lesions number (<5, 5-20, and >20). The majority of patients showed focal and combined infiltration patterns with bone lesions predominantly distributed in the spine and pelvis. As skull and lower limbs are less frequently involved by focal bone lesions, excluding them from the standard MRI protocol allows to obtain a shorter protocol, maintaining a good diagnostic value.

Abstract
Monoclonal gammopathy of undetermined significance (MGUS) precedes multiple myeloma (MM). Population-based screening for MGUS could identify candidates for early treatment in MM. Here we describe the Iceland Screens, Treats, or Prevents Multiple Myeloma study (iStopMM), the first population-based screening study for MGUS including a randomized trial of follow-up strategies. Icelandic residents born before 1976 were offered participation. Blood samples are collected alongside blood sampling in the Icelandic healthcare system. Participants with MGUS are randomized to three study arms. Arm 1 is not contacted, arm 2 follows current guidelines, and arm 3 follows a more intensive strategy. Participants who progress are offered early treatment. Samples are collected longitudinally from arms 2 and 3 for the study biobank. All participants repeatedly answer questionnaires on various exposures and outcomes including quality of life and psychiatric health. National registries on health are cross-linked to all participants. Of the 148,704 individuals in the target population, 80 759 (54.3%) provided informed consent for participation. With a very high participation rate, the data from the iStopMM study will answer important questions on MGUS, including potentials harms and benefits of screening. The study can lead to a paradigm shift in MM therapy towards screening and early therapy.

Abstract
Multiple myeloma (MM) is a common hematological disease characterized by the accumulation of clonal malignant plasma cells in the bone marrow. Over the past two decades, new therapeutic strategies have significantly improved the treatment outcome and patients survival. Nevertheless, most MM patients relapse underlying the need of new therapeutic approaches. Plasma cells are prone to produce large amounts of immunoglobulins causing the production of intracellular ROS. Although adapted to high level of ROS, MM cells die when exposed to drugs increasing ROS production either directly or by inhibiting antioxidant enzymes. In this review, we discuss the efficacy of ROS-generating drugs for inducing MM cell death and counteracting acquired drug resistance specifically toward proteasome inhibitors.

Abstract
Multiple myeloma (MM) remains a challenge to treat, and its precise pathogenic mechanisms have not been fully clarified. The present study aimed to evaluate the relation between long non-coding RNA transcription factor 7 (lnc-TCF7) and clinical features, as well as the prognosis of patients with MM, and to determine the effects of lnc-TCF7-knockdown on the regulation (and regulatory mechanisms) of MM progression. lnc-TCF7 expression was detected in the bone marrow plasma cells of 86 patients with MM and 30 healthy controls. In patients with MM, the clinical data were collected, and event-free survival (EFS) and overall survival (OS) analyses were conducted. In vitro, lnc-TCF7 expression was detected in MM cell lines and normal bone marrow plasma cells. Using Roswell Park Memorial Institute 8226 cells, functional experiments were conducted following lnc-TCF7 short hairpin (sh)RNA transfection, and compensation experiments were performed after lnc-TCF7 shRNA transfection alone and in combination with a microRNA (miR)-203 inhibitor. lnc-TCF7 expression was increased in patients with MM compared with the healthy controls and was positively related to β-2-microglobulin expression and International Staging System stage, while negatively associated with complete response, EFS and OS. In vitro, lnc-TCF7 was upregulated in MM cells compared with normal bone marrow plasma cells, and its knockdown suppressed MM cell proliferation while promoting apoptosis. Compensation experiments showed that miR-203 inhibition promoted MM progression by regulating the Jagged1-Notch1 signaling pathway in lnc-TCF7-knockdown cells. In conclusion, increased lnc-TCF7 expression was related to deteriorating clinical features and prognosis, and lnc-TCF7-knockdown inhibited disease progression by regulating the miR-203-mediated Jagged1-Notch1 signaling pathway activation in MM.

Association of serum calcium levels with renal impairment and all-cause death in Chinese patients with newly diagnosed multiple myeloma: a cross-sectional, longitudinal study. Nutr Metab (Lond) 2021; 18:19. [PMID: 33573678 PMCID: PMC7879693 DOI: 10.1186/s12986-020-00525-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Accepted: 11/21/2020] [Indexed: 11/17/2022] Open
Abstract
Background More studies have shown that serum calcium has a crucial role in many types of cancers. However, few studies have determined the association between serum calcium levels and renal impairment (RI) and all-cause death in Chinese patients with multiple myeloma (MM).
Methods A total of 246 of 565 participants who were followed for > 6 months from a MM cohort at our institution were eligible for the retrospective study. A generalized additive model and smooth curve fitting were performed to investigate the cross-sectional relationship between the serum calcium level and RI at baseline. Multivariate-adjusted Cox regression models were fitted to assess the associations between baseline serum calcium levels and the onset of end-stage renal disease (ESRD) or death in patients with MM. Results A total of 172 of 565 patients (30.4%) with newly diagnosed MM presented with RI. The mean duration of follow-up was 26.64 months. Twenty-one patients (8.54%) died and 28 patients (11.52%) had ESRD. In patients with a serum calcium level > 2.30 mmol/L, the serum calcium level was independently associated with the occurrence of MM-related RI. Cox regression analysis showed that baseline serum calcium levels were consistently associated with a higher risk of all-cause death in the fully adjusted model, but were not associated with the occurrence of ESRD. When patients were categorized into two groups according to baseline mean serum calcium level, deaths occurred in 13 patients (15.1%) with a mean serum calcium level > 2.44 mmol/L compared to eight patients (5.0%) with a mean serum calcium level < 2.44 mmol/L (p < 0.05); Eighteen patients (11.46%) with a mean serum calcium level < 2.44 mmol/L progressed to ESRD compared to 13 patients (11.6%) with a serum calcium level > 2.44 mmol/L (p > 0.05).
Conclusions This observational study showed that there was a nonlinear relationship between the serum calcium level and the presence of RI in patients with MM. An elevated baseline calcium level predicted all-cause death, but did not predict the occurrence of ESRD in patients with MM followed for > 6 months.

Abstract
The aim of the present study was to investigate the association of long non-coding RNA T cell factor 7 (lncRNA TCF7) with disease risk, prognosis and its cellular function in multiple myeloma (MM). A total of 132 de novo symptomatic patients with MM and 50 controls were enrolled. Plasma cells from patients with MM and controls were separated from bone marrow samples to detect lncRNA TCF7 expression using reverse transcription-quantitative PCR. In addition, treatment responses, event-free survival (EFS) and overall survival (OS) were measured. The effects of lncRNA TCF7 on proliferation, apoptosis and microRNA-200c (miR-200c) expression were assessed by gain- and loss-of-function experiments in RPMI-8226 and U-266 cells. The results demonstrated that lncRNA TCF7 expression was upregulated in patients with MM compared with controls, and the receiver operating characteristic curve revealed that lncRNA TCF7 could distinguish patients with MM from controls with an area under the curve of 0.793 (95% CI, 0.725-0.861). In patients with MM, high lncRNA TCF7 expression was associated with higher β2-microglobulin, more advanced International Staging System stage and increased t (14; 16) mutations. Furthermore, it was demonstrated that lncRNA TCF7 was downregulated in patients with complete response (CR) compared with patients without CR. Furthermore, high lncRNA TCF7 expression predicted worse EFS and OS. lncRNA TCF7 also promoted cell proliferation, whereas it reduced cell apoptosis and miR-200c expression in RPMI-8226 and U-266 cells. In conclusion, the present results suggested that lncRNA TCF7 may be used as a potential biomarker and as a treatment target for MM.

Abstract
BACKGROUND Real-world multiple myeloma (MM) data are scarce, with most data originating from clinical trials. The Myeloma and Related Diseases Registry (MRDR) is a prospective clinical-quality registry of newly diagnosed cases of plasma cell disorders established in 2012 and operating at 44 sites in Australia and New Zealand as of April 2020. METHODS We reviewed all patients enrolled onto the MRDR between June 2012 and April 2020. Baseline characteristics, treatment, and outcome data were reviewed for MM patients with comparisons made by chi-square tests (categorical variables) and rank sum tests (continuous variables). Kaplan-Meier analysis was used to estimate progression-free survival and overall survival (OS). RESULTS As of April 2020, a total of 2405 MM patients were enrolled (median age, 67 years, with 40% aged > 70 years). High-risk features were present in 13% to 31% of patients: fluorescence in-situ hybridization (FISH) ≥ 1 of t(4;14), t(14;16), or del(17p) 18%, International Staging System (ISS)-3 31%, and Revised ISS (R-ISS)-3 13%. Cytogenetic/FISH analyses were performed in 50% and 68% of patients, respectively, with an abnormal karyotype result in 34%. Bortezomib-containing therapy was the most common first-line therapy (79.3%, n = 1706). Patients not receiving bortezomib were older (median age, 76 vs 65 years, P < .001) with inferior performance status (Eastern Cooperative Oncology Group performance status ≥ 2, 41% vs 18%, P < .001). Median progression-free survival and OS were 30.8 and 65.8 months, respectively. Younger patients had superior OS (76.3 vs 46.7 months, P < .001, < 70 and ≥ 70 years, respectively). R-ISS score was available in 50.7% (n = 1220) of patients, and higher R-ISS was associated with inferior OS (R-ISS-1 vs R-ISS-2 vs R-ISS-3: not reached vs 68.1 months vs 33.2 months, respectively, P < .001). CONCLUSION Clinical registries provide a more complete picture of MM diagnosis and treatment, and highlight the challenges of adhering to best practices in a real-world context.

Tournaire G, Conte C, Perrot A, Lapeyre-Mester M, Despas F. Vaccination during the First Diagnosis of Multiple Myeloma: A Cohort Study of the French National Health Insurance Database. Vaccines (Basel) 2020; 8:vaccines8040722. [PMID: 33276450 PMCID: PMC7712872 DOI: 10.3390/vaccines8040722] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 11/23/2020] [Accepted: 11/29/2020] [Indexed: 12/21/2022] Open
Abstract
Purpose: Infections are frequent and often result in serious complications in patients with multiple myeloma (MM). Prophylactic vaccination is recommended for influenza virus, Streptococcus pneumoniae (SP), and Hemophilus influenzaeb (Hib). The aims of this study were to measure the vaccination rates within 24 months after the diagnosis of multiple myeloma and to identify factors associated with vaccine use. Methods: MM patients were selected through the French national health insurance database from 1 January 2010 to 31 December 2015. Patients with a previous history of MM were excluded. Results: Vaccination rates against influenza, SP, and Hib among 22,831 newly diagnosed MM patients were, respectively, 28.5%, 10.3%, and 1.4%. Only 0.7% received all three vaccines. Factors associated with vaccination were young age, male gender, an absence of comorbidity, a history of higher medication and vaccine consumption, Herpes simplex virus (HSV), Varicella zoster virus (VZV), and the use of pneumocystis prophylaxis. Conclusion: The low rates of vaccination indicate the need to improve physician and MM patient adherence and education regarding vaccination.

Budget impact analysis of the use of oral and intravenous therapy regimens for the treatment of relapsed or refractory multiple myeloma in Germany. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2020; 21:1351-1361. [PMID: 32654072 PMCID: PMC7581591 DOI: 10.1007/s10198-020-01219-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Accepted: 07/03/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND In Germany, several triplet therapies for treating relapsed or refractory multiple myeloma (rrMM) patients have recently been approved. While most of them are administered intravenously, ixazomib-based combination is the only orally bioavailable regimen. OBJECTIVE To conduct a 1-year and 3-year budget impact analysis (BIA) of different novel triplets to treat patients with rrMM in second or subsequent therapy lines accounting for costs covered by German statutory health insurance (SHI). METHODS A 3-state partitioned survival model (PSM) was developed to evaluate the budget impact of the following regimens: carfilzomib plus lenalidomide plus dexamethasone (KRd), elotuzumab plus lenalidomide plus dexamethasone (ERd), daratumumab plus lenalidomide plus dexamethasone (DRd), and ixazomib plus lenalidomide plus dexamethasone (IRd). The analysis included direct medical costs such as drug acquisition, comedication and preparation for parenteral solutions, drug administration and other 1-time costs, adverse event management costs and direct non-medical costs, such as transportation costs. RESULTS Based on current drug market shares in German healthcare market, the estimated costs after 1 year of treatment was €551 million (KRd), €163 million (ERd), €584 million (DRd), and €95 million (IRd). The total budget impact of €1393 million is mainly driven by drug acquisition and subsequent therapy costs. CONCLUSION Among the regimens of interest, the oral-based therapy regimens offered cost advantages over intravenous-based therapy regimens. The higher overall costs of intravenous therapy regimens were attributed primarily to higher drug acquisition costs.

PLoS One 2020; 15:e0241778. [PMID: 33147257 PMCID: PMC7641449 DOI: 10.1371/journal.pone.0241778] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Accepted: 10/20/2020] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Autologous stem cell transplantation (ASCT) remains the standard of care for young multiple myeloma (MM) patients; indeed, at-home ASCT has been positioned as an appropriate therapeutic strategy. However, despite the use of prophylactic antibiotics, neutropenic fever (NF) and hospital readmissions continue to pose as the most important limitations in the outpatient setting. It is possible that the febrile episodes may have a non-infectious etiology, and engraftment syndrome could play a more significant role. The aim of this study was to analyze the impact of both G-CSF withdrawal and the addition of primary prophylaxis with corticosteroids after ASCT. METHODS Between January 2002 and August 2018, 111 MM patients conditioned with melphalan were managed at-home beginning +1 day after ASCT. Three groups were established: Group A (n = 33) received standard G-CSF post-ASCT; group B (n = 32) avoided G-CSF post-ASCT; group C (n = 46) avoided G-CSF yet added corticosteroid prophylaxis post-ASCT. RESULTS The incidence of NF among the groups was reduced (64%, 44%, and 24%; P<0.001), with a non-significant decrease in hospital readmissions as well (12%, 6%, and 2%; P = 0.07). The most important variables identified for NF were: HCT-CI >2 (OR 6.1; P = 0.002) and G-CSF avoidance plus corticosteroids (OR 0.1; P<0.001); and for hospital readmission: age ≥60 years (OR 14.6; P = 0.04) and G-CSF avoidance plus corticosteroids (OR 0.07; P = 0.05). CONCLUSIONS G-CSF avoidance and corticosteroid prophylaxis post ASCT minimize the incidence of NF in MM patients undergoing at-home ASCT. This approach should be explored in a prospective randomized clinical trial.

Vertical cutoff methods in serum protein electrophoresis for the measurement of monoclonal protein concentrations: Which is best? Clin Chim Acta 2020; 510:573-580.

Abstract
BACKGROUND Monoclonal protein (M-protein) concentrations are measured by serum protein electrophoresis (SPE). Two methods are used for demarcating the M-protein area in the electropherogram: perpendicular drop (PD) and tangent skimming (TS). The aim of this study was tocompare both methods and to establish which is the most accurate and precise. METHODS We studied 24 sera containing M-protein (5-44 g/L). The systematic error (SE) was evaluated in a dilution series of 12 sera. Within-day, between-day, and interobserver variability were assessed. SPE was performed by capillary and agarose gel electrophoresis. M-protein concentrations were measured using both cutoff methods. RESULTS The PD method shows a constant SE ranged 1.00-2.27 g/L, while constant SE for TS is ranged -0.30--0.57 g/L. None of the cutoff methods or electrophoretic methods showed a proportional SE, with the exception of the TS method in capillary electrophoresis for β-migrating M-protein. The PD method was more precise than the TS method in all three estimates of imprecision. An increased CV for concentrations < 10 g/L in between-day imprecision was observed with the TS method. Interobserver imprecision was greater for M-protein concentrations < 17 g/L for both cutoff methods (14.85%, 26.42% respectively). CONCLUSIONS Despite being less precise, the TS method provides a more accurate measurement of M-protein concentration.

Abstract
BACKGROUND Serum free light chain (sFLC) quantitation is central for plasma cell dyscrasias. Several assays are available and switching sFLC methods may be advantageous in certain laboratories. This study performed Freelite and Seralite simultaneously for samples received by the clinical laboratory over a 10 month period and compared quantitation and its impact on interpretation of patient results. METHODS Patients (N = 189) included multiple myeloma (MM) and related plasma cell cancers, monoclonal gammopathy of unknown significance (MGUS), AL amyloidosis and renal impairment. sFLC quantitation and clinical agreement was assessed between methods. RESULTS Clinical agreement was substantial at diagnosis (κ = 0.647, p < .01) and moderate for monitoring (κ = 0.591, p < .01). Good concordance was seen for MM and related plasma disorders and MGUS, with poorer agreement seen for AL amyloidosis. Case studies illustrated agreement in pattern of myeloma disease activity. Bland-Atman plots showed small mean bias but increasing variation between methods with increasing FLC concentrations. Passing-Bablok analysis confirmed systematic differences in quantitation between methods. CONCLUSIONS Despite differences in quantitation, overall, agreement was seen between the different sFLC platforms in relation to the clinical interpretation. As a rapid test without the need for large and expensive analysers, Seralite may be highly applicable in certain laboratories to enable in-house testing.

Abstract
OBJECTIVE To evaluate changes in diagnostic and therapeutic approach in multiple myeloma among Norwegian hematologists in the current decade. METHODS This nationwide study in Norway is based on results of surveys conducted among professionally active hematologists from 2013 to 2019. Every year, respondents participating in the survey suggested treatment regimens used in typical clinical situations in patients with multiple myeloma, as well as diagnostic routines. RESULTS The use of regimens containing alkylators and thalidomide was common at the beginning of the studied period. Later, lenalidomide became the most preferred treatment in most first-line patients. Bortezomib maintained a stable position in the treatment of myeloma in patients with renal insufficiency. The lenalidomide, bortezomib, and dexamethasone combination became the preferred frontline triplet for transplant-ineligible patients and induction therapy before transplant. Nowadays, the relapse after lenalidomide-based treatment is managed using both bortezomib-based therapies and combinations with the newest agents. Together with the therapeutic landscape, the use of diagnostic criteria and workup as well as supportive care changed in the period influenced by local and international guidelines and recommendations. CONCLUSION Norwegian hematologists gradually adopt new clinical concepts, guidelines, and recommendations in their practice.

Abstract
Hepatitis C virus (HCV) represents the major risk factor for mixed cryoglobulinemia (MC), a small-vessel vasculitis that may evolve into an overt B-cell non-Hodgkin's lymphoma. Here, we aimed to identify a biomarker signature for the early diagnosis of minimal residual disease (MRD). We assessed free light chains (FLCs), IgM k,and IgM λ heavy/light chain (HLC) pairs, and vascular endothelial growth factor (VEGF) in sera from 34 patients with MC vasculitis (32 HCV- and 2 HBV-related), treated with low-dose rituximab (RTX). FLCs and IgM HLCs were measured by turbidimetric assay; VEGF by an enzyme-linked immunosorbent assay. After RTX, the positive (complete + partial) clinical and laboratory responses were of 85.29% and 50%, respectively; in contrast, the mean levels of FLCs, IgM HLCs, and VEGF were substantially unaffected in most patients and still above the normal range. In those achieving a reduction of FLCs and IgM k and λ chains values within the range of normality, we found that post-treatment free λ chains and IgM k values correlated with clinical and laboratory response. Our results suggest that high levels of FLCs, IgM HLCs, and VEGF could represent the signature of "dormant" B cell clones' activity that could be very useful to identify MRD indicative of possible relapse or worsening outcome.

Abstract
PURPOSE OF THE STUDY In the past years, high dose chemotherapy (HDT) with autologous stem cell transplantation (ASCT)has more extensively been performed in elderly patients with multiple myeloma (MM). Several studies found a similar survival benefit compared to younger patients. The objective of our retrospective study is to analyse the tolerability of HDT + ASCT in elderly patients. PATIENTS AND METHODS We compared 26 ASCT performed in MM patients ≥65 years to 127 ASCT in patients <65 years by evaluating treatment-tolerability, length of hospital stay and number of transfusions. RESULTS There was no significant difference in the duration of hospitalisation (16 days (range 14-47) in the elderly vs. 17 days (range 14-71) days, P = 0.0903), median time of cytopenia (neutrophils<500/μl: 5 days (range 4-24) vs. 6 days (range 3-28) days, P = 0.1091; platelets<30 000/μl: 6 days (range 3-36) vs. 7 days (range 0-53) days, P = 0.274) or incidence of, or degree of complications between the two age-groups. Immediate and day 100 treatment related mortality (TRM) was comparable in both groups (3.85% vs. 1.58%, P = 0.4304). CONCLUSION our findings support the concept that HDT + ASCT can be safely administered as first-line option for well-selected patients≥65 years.

Abstract
Renal failure is a common feature of multiple myeloma affecting 20-55% of patients at the initial presentation and is being associated with a significant increase in morbidity and mortality. Renal transplantation for patients with multiple myeloma is rarely considered given the incurable nature of the disease, the risk of post-transplant disease progression and perceived high risk of infections. Here we report a 57-year-old man with end-stage renal failure attributed to presumed IgA nephropathy, with pre-existing stable multiple myeloma, who received a kidney transplant from a two haplotype-matched sibling. Transplantation has been successful and with excellent kidney function and stable multiple myeloma 6 years post-transplant. This case highlights the potential benefits of renal transplantation in highly selected patients with multiple myeloma.
