Skeletal-Related Events in Patients With Multiple Myeloma: A Comprehensive Retrospective Cohort Study. J Korean Med Sci 2024; 39:e175. [PMID: 38859738 PMCID: PMC11164652 DOI: 10.3346/jkms.2024.39.e175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Accepted: 05/07/2024] [Indexed: 06/12/2024] Open
Abstract
BACKGROUND Multiple myeloma (MM) patients are at risk of skeletal-related events (SREs) like spinal cord compression, pathologic fractures, bone surgery, and radiation to bone. Real-world data regarding SREs in MM are limited. METHODS We conducted a large, retrospective, nationwide cohort study using the Korean Health Insurance Review and Assessment Service (HIRA) database from 2007 to 2018. RESULTS Over a 12-year study period, we identified 6,717 patients who developed symptomatic MM. After a median follow-up of 35.1 months (interquartile range [IQR], 20.8-58.2 months), 43.6% of these patients experienced SREs, and 39.6% had four or more SREs. One in five patients (20.0%) experienced pathologic fractures within the first year of follow-up. The median time to first SRE was 9.6 months (IQR, 1.2-25.8 months), with 3.0 months in the group with prior SREs and 19.8 months in the group without prior SREs. During follow-up, 78.5% of patients received bisphosphonates. Multiple logistic regression analysis revealed several factors associated with an increased risk of SREs, including being female (odds ratio [OR], 1.44), aged 50 or older (OR, 1.87), having cerebrovascular disease (OR, 1.34), undergoing first-line chemotherapy regimens not containing bortezomib or lenalidomide (OR, 1.49), and being in the group with prior SREs and bisphosphonate use (OR, 5.63), compared to the group without prior SREs and without bisphosphonate use. CONCLUSION This population-based study is the first to report the incidence and risk factors of SREs in Korean MM patients, which can be used to assess their bone health.

Abstract
PURPOSE Intravenous (IV) bisphosphonates reduce the risk of skeletal-related events in patients with multiple myeloma (MM). However, data describing racial differences in IV bisphosphonate utilization outside of clinical trial settings are limited. We evaluated population-level IV bisphosphonate initiation and discontinuation among patients of age ≥ 65 years with MM. METHODS We conducted a retrospective cohort study of patients of age ≥ 65 years diagnosed with first primary MM between 2001 and 2011. Patients were identified using the SEER-Medicare linked database and followed through December 2013. Cumulative incidences of IV bisphosphonate initiation and time to discontinuation among users were compared between racial and ethnic groups. In Fine and Gray competing risk models, we estimated subdistribution hazard ratios (SHRs) and 95% CIs for initiation and discontinuation. RESULTS We included 14,231 eligible patients with MM (median age, 76 years; 52% male). Over a median follow-up of 23.1 months, 54% of patients received at least one IV bisphosphonate dose. Our final analytical sample included 10,456 non-Hispanic (NH) Whites, 2,267 NH Blacks, 548 Asian and Pacific islanders, and 815 Hispanic and Latino patients. A higher proportion of White patients (56.1%) newly received IV bisphosphonates after MM diagnosis compared with NH Blacks (45.4%). Compared with White patients, NH Black patients were less likely to initiate IV bisphosphonates (SHR, 0.74; 95% CI, 0.70 to 0.79) and slightly more likely to discontinue treatment (SHR, 1.10; 95% CI, 1.01 to 1.19). CONCLUSION Approximately half of the patients with MM of age ≥ 65 years did not receive IV bisphosphonates, with significant delay among racial minority groups. These findings highlight the need for improvement of IV bisphosphonate uptake in patients with MM of age ≥ 65 years.

Abstract
PURPOSE To describe use of bisphosphonates in newly diagnosed multiple myeloma patients in Denmark. METHODS Using data from the Danish National Multiple Myeloma Registry, we conducted a population-based cohort study. Among patients newly diagnosed with multiple myeloma from 2005 to 2015, we examined use of bisphosphonates at first- and at progression/second-line anti-myeloma treatment overall, by patient characteristics, and myeloma complications. RESULTS Of 2947 patients starting first-line anti-myeloma treatment, 2207 patients (74.9%) received bisphosphonates. During a median follow-up of 27.6 (quartiles, 10.6-52.5) months, disease progression post-first-line treatment was recorded in 1546 patients, of whom 1065 (68.9%) were treated with bisphosphonates. Altogether, 80.9% of patients with and 37.6% of patients without myeloma bone disease were treated with bisphosphonates at first line and 73.0% and 42.7%, respectively, at progression/second line. Moreover, the proportion of patients treated with bisphosphonates decreased with increasing severity of renal impairment at first and at progression/second-line treatment. CONCLUSION The proportion of patients treated with bisphosphonates as part of first- and second-line anti-myeloma treatment increased with presence of myeloma bone disease and decreased by presence and severity of renal impairment. Overall, 25% of newly diagnosed multiple myeloma patients had no record of bisphosphonate treatment, potentially indicating an unmet need.

Abstract
Multiple myeloma treatment has evolved with approvals of new immunomodulatory imide drugs (IMiDs), monoclonal antibodies (MoABs), and proteasome inhibitors (PIs). We characterized U.S. treatment trends and survival from 2011 to 2019 using Flatiron data from multiple myeloma patients followed from treatment index until death/end of data. Patients (n = 10,553) were primarily (88%) treated in community centers. Frontline PI-IMiD-dexamethasone use increased over time, while IMiD-dexamethasone and PI-dexamethasone use decreased. MoAB-IMiD-dexamethasone use increased in relapsed/refractory disease. In all lines, use of doublets decreased and triplets increased, with triplets becoming the most prescribed combination by 2018-2019, especially in first line (62%). Monotherapy use decreased in first line (19% to 10%) but remained steady in relapsed/refractory disease (∼20%). With each increasing line of therapy, median overall survival decreased (60, 48, 36, 29, 23 months). Survival increased with more recent diagnosis. Our results indicate that the multiple myeloma landscape has evolved significantly in the last decade.

Abstract
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.

Abstract
RATIONALE While treatment strategies for multiple myeloma have evolved radically over the last decades, little is known about the risk of fractures for symptomatic multiple myeloma patients over time. OBJECTIVE To determine the effect of different treatment periods (1996-2000, 2001-2006 and 2007-2011) on the risk of fractures in patients with multiple myeloma. METHODS This retrospective case-control study included patients with multiple myeloma in Denmark, using the Danish National Health Service. Cases were defined as patients who had sustained a fracture between 1996 and 2011, and controls were those without a fracture. Exposure was defined as an ICD code for multiple myeloma. Vertebral fractures, gender, and age were considered in secondary analyses. Conditional logistic regression was used to estimate odd ratios (ORs) of fracture risk, and the analyses were adjusted for comorbidities and recent drug use. RESULTS The study population consisted of 925,341 cases, and the same number of matched controls, of whom 1334 patients with multiple myeloma. Among cases, the risk of any fracture was higher in multiple myeloma patients compared to patients without multiple myeloma (any fracture: ORadj[95% CI] 1996-2000: 1.7[1.3-2.3]; 2001-2006: 1.3[1.1-1.6]; 2007-2011: 1.7[1.4-2.2]). Although fractures were mainly non-vertebral, the risk of vertebral fractures in particular was higher in multiple myeloma patients (vertebral fracture: ORadj[95% CI] 1996-2000: 3.5[1.4-8.6]; 2001-2006: 4.0[1.9-8.2]; 2007-2011: 3.0[1.6-5.7]). CONCLUSIONS Despite new treatment strategies and improved supportive care, this study showed no decreased fracture risk for multiple myeloma patients over time. New treatment strategies, even if they have a positive impact on overall survival, offer no guarantee for a corresponding reduction in bone lesions.

Bone complications in patients with multiple myeloma in five European countries: a retrospective patient chart review. BMC Cancer 2020; 20:170.

Abstract
BACKGROUND Bone complications (pathologic fracture, spinal cord compression, surgery to bone and radiation to bone) are a common problem in patients with multiple myeloma (MM). We set out to provide insights into the real-world burden of bone complications in patients with newly diagnosed MM (NDMM). METHODS We conducted a retrospective review of medical charts of patients with NDMM whose disease had progressed following first-line treatment in the 3 months before data collection in 2016 in five European countries (France, Germany, Italy, Spain and the United Kingdom). RESULTS The aggregated study population included 813 patients. Bone pain commonly led to MM diagnosis (63%) and 74% of all patients had two or more bone lesions at initiation of first-line treatment. Furthermore, 26% of patients experienced a new bone complication between MM diagnosis and disease progression following first-line treatment, despite 75% of individuals receiving bisphosphonates. Most bone complications (52%) occurred in the period before initiation of first-line treatment (mean duration: 2.3 months) and more than half of patients (56%) who experienced a new bone complication were hospitalised. Analgesics were used more frequently in patients with bone complications than in those without them (76% vs 50%, respectively). Furthermore, 51% of patients had renal impairment by the time first-line treatment was started. Overall, 25% of patients did not receive bisphosphonates for prevention of bone complications and one in four of those with renal impairment at initiation of first-line treatment did not receive bisphosphonates. CONCLUSIONS Bone complications are common in patients with NDMM. They are frequently associated with hospitalization and analgesic use. Data from this study, conducted in the era of novel anti-myeloma therapies and before the approval of denosumab for use in patients with MM, suggest that although most patients (75%) received bisphosphonates, use of anti-resorptive therapy for prevention of bone complications may be suboptimal in patients with NDMM, irrespective of renal function.

Abstract
AIM To compare healthcare resource use and costs between newly diagnosed multiple myeloma (NDMM) patients with and without skeletal-related events (SREs). METHODS Adults newly diagnosed with MM (1 January 2006 and 30 June 2017) with at least 12 months continuous health coverage prior to diagnosis were identified using the IBM MarketScan administrative claims. To control for baseline differences, NDMM patients with SREs were propensity score matched to NDMM patients without SREs. Outcomes included annual HRU and costs during follow-up along with number and type of SREs (SRE cohort only). Patients with SREs were stratified by number of SREs, and annual SRE-related costs were reported. Student's t test and Chi-squared test were used to compare outcomes. RESULTS Before matching, the 6648 patients in the SRE cohort had more comorbidities, were more likely to have MM treatment, and had higher pre-index healthcare costs than the 7458 patients in the non-SRE cohort. After matching, cohorts of 3432 patients were well balanced on baseline characteristics. Patients with SREs (vs. without SREs) had significantly higher inpatient, outpatient, and pharmacy HRU. Patients with SREs had significantly higher mean annual all-cause healthcare costs ($213,361 vs. $94,896, p < 0.001) with hospitalization being the leading driver of increased costs (38.7% of total). Among 6648 patients with SREs, the mean annual SRE-related healthcare costs were $39,603, $45,463, and $50,111 for patients with one, two, and three or more events, respectively. CONCLUSIONS NDMM patients with SREs have more than twice the all-cause healthcare costs than matched patients without SREs. Costs increase with the number of SRE events.

Underutilization of guideline-recommended supportive care among older adults with multiple myeloma in the United States. Cancer 2019; 125:4084-4095. [PMID: 31381151 DOI: 10.1002/cncr.32428] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2019] [Revised: 05/20/2019] [Accepted: 06/07/2019] [Indexed: 12/19/2022]
Abstract
BACKGROUND With improving survival for patients with multiple myeloma (MM), supportive care that is focused on optimizing quality of life and minimizing treatment-related toxicities is increasingly important. The extent to which patients with MM are receiving recommended supportive care is unknown. METHODS This study used the Surveillance, Epidemiology, and End Results-Medicare database to identify older adults (age ≥66 years) diagnosed with MM in 2008-2013 who had received active treatment and survived 1 year or longer after their diagnosis. Outcomes of interest included guideline-recommended supportive care, which was defined as 1) bone-modifying drugs (BMDs) within the 12 months after the diagnosis, 2) influenza vaccination in the first season after the diagnosis, and 3) concomitant use of prophylactic antivirals with proteasome inhibitors. Multivariable logistic regression models were used to evaluate associations between patient/facility-level characteristics and supportive care use. RESULTS Among 1996 patients receiving MM-directed therapy, 64%, 52%, and 49% received BMDs, an influenza vaccination, and antiviral prophylaxis, respectively. Non-Hispanic black patients (odds ratio [OR] vs white patients, 0.63; 95% confidence interval [CI], 0.46-0.88) and patients with baseline renal impairment (OR, 0.43; 95% CI, 0.34-0.54) had lower odds of BMDs. Non-Hispanic blacks (OR, 0.52; 95% CI, 0.37-0.73) and those with dual Medicaid enrollment (OR, 0.76; 95% CI, 0.58-0.99) had lower odds of influenza vaccination. Treatment in a community-based setting was associated with reduced odds of antiviral prophylaxis (OR, 0.58; 95% CI, 0.46-0.72). CONCLUSIONS Substantial underutilization of guideline-recommended supportive care was observed among older adults with MM in the United States, and this was associated with both patient and facility characteristics. Targeted interventions are needed to improve supportive care for patients with MM.

Abstract
Aim: The approved indication for denosumab (120 mg) was expanded in 2018 to include skeletal-related event (SRE) prevention in patients with multiple myeloma (MM). Therefore, a cost-effectiveness analysis was conducted comparing denosumab with zoledronic acid (ZA) for SRE prevention in patients with MM from the national healthcare system perspective in a representative sample of European countries: Austria, Belgium, Greece, and Italy. Methods: The XGEVA global economic model for patients with MM was used to calculate incremental cost-effectiveness ratios (ICERs) for denosumab vs ZA over a lifetime horizon. Clinical inputs were derived from the denosumab vs ZA randomized, phase 3 study ("20090482") in patients newly-diagnosed with MM, and comprised real-world adjusted SRE rates, serious adverse event (SAE) rates, treatment duration, dose intensity, progression-free survival (PFS), and overall survival (OS). Economic inputs comprised country-specific denosumab and ZA acquisition and administration costs, SRE and SAE management costs, and discount rates. Health utility decrements associated with MM disease progression, SRE and SAE occurrence, and route of administration were included. Results: Estimated ICERs (cost per quality-adjusted life-year [QALY] gained) for denosumab vs ZA in Austria, Belgium, Greece, and Italy were €26,294, €17,737, €6,982, and €27,228, respectively. Using 1-3 times gross domestic product (GDP) per capita per QALY as willingness to pay thresholds, denosumab was 69-94%, 84-96%, 79-96%, and 50-92% likely to be cost-effective vs ZA, respectively. Limitations: Economic inputs were derived from various sources, and time to event inputs were extrapolated from 20090482 study data. Conclusions: Denosumab is cost-effective vs ZA for SRE prevention in patients with MM in Austria, Belgium, Greece, and Italy, based on often-adopted World Health Organization thresholds. This conclusion is robust to changes in model parameters and assumptions. Cost-effectiveness estimates varied across the four countries, reflecting differences in healthcare costs and national economic evaluation guidelines.

J Bone Oncol 2018; 14:100215.

Abstract
Skeletal-related events (SREs) are common bone complications in multiple myeloma (MM). However, there are few real-world reports of their incidence. In this study, a database of oncology electronic health records was linked to administrative claims data. Patients identified were aged ≥18 years and newly diagnosed with MM, had ≥1 clinic visit within 1 month of diagnosis, and ≥1 year of follow-up after diagnosis. The study period was January 1, 2011 to December 31, 2016. 343 patients were included, 35% of whom had a baseline history of any SRE. During a median follow-up of 25.7 months, 34% of patients experienced SREs after diagnosis. Median time to SRE was 167 days. Among patients experiencing an SRE, 68% had an SRE within the first year. The incidence rate of SREs at 1 year following MM diagnosis for patients with baseline history was 103/100 person-years (PY) versus 16/100PY for patients without baseline history. SRE incidence rates within 3 months of initiating a line of therapy increased with subsequent lines (line 1: 81/100PY, line 2: 118/100PY, line 3: 150/100PY). Risk of SREs was similar across different anti-MM regimens, including proteasome inhibitor-based regimens. These results highlight the importance of continued surveillance and management of MM-associated bone disease.

Initiation and interruption in intravenous bisphosphonate therapy among patients with multiple myeloma in the United States. Cancer Med 2018; 8:374-382. [PMID: 30537194 PMCID: PMC6346250 DOI: 10.1002/cam4.1869] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2018] [Accepted: 10/22/2018] [Indexed: 01/06/2023] Open
Abstract
BACKGROUND Prior to 2018, intravenous bisphosphonates (IV BPs) were the only therapies recommended to prevent skeletal-related events for patients diagnosed with multiple myeloma (MM). We examined patterns of IV BP initiation and interruption among patients with newly diagnosed MM (NDMM) in the United States. METHODS Electronic health records linked to administrative health insurance claims were used to identify adults with NDMM between 1 January 2011 and 30 April 2016. Patients were excluded for recent IV BP use or concurrent cancer. The incidences of IV BP initiation and interruption were estimated using competing risk regression. A generalized linear model was used to estimate risk factors for treatment initiation and interruption. RESULTS Among the 547 patients with NDMM, 64% initiated MM therapy within 30 days of diagnosis. By one year, 65% (95% CI: 59, 70) of patients with appropriately timed anti-MM therapy had initiated an IV BP. Zoledronic acid was the most commonly initiated IV BP. Patients with Stage III MM were more likely to initiate an IV BP (adjusted risk difference (RD): 6.3; 95% CI: 2.7, 10.1), while those with eGFR <30 mL/min were less likely to initiate (RD: -9.7; 95% CI: -13.8, -5.8). Of the 264 patients who initiated an IV BP, 77% (95% CI: 71, 82) experienced an interruption within one year. Patients on concurrent anti-MM therapy were less likely to experience an interruption in IV BP therapy. CONCLUSIONS Many patients with NDMM do not initiate IV BPs, particularly those with renal complications. Interruptions of IV BPs were common.
