Reduction in Late Mortality Among Patients With Multiple Myeloma Treated With Autologous Peripheral Blood Stem Cell Transplantation-A Blood or Marrow Transplant Survivor Study Report.

ABSTRACT: Therapeutic practices for multiple myeloma (MM) have evolved, such that novel-agent-based therapy and autologous peripheral blood stem cell transplantation (aPBSCT) is the current standard. Whether cause-specific mortality has changed with time remains unclear. We examined late cause-specific mortality among patients with MM receiving aPBSCT from 1989 to 2014. We conducted a prospective cohort study using participants enrolled in the enrolled in the Blood or Marrow Transplant Survivor Study. We created 3 eras to reflect changing MM therapy: <2000 (pre-thalidomide); 2000-2005 (thalidomide); 2006-2014 (lenalidomide). We used Kaplan-Meier techniques and Cox regression for examining all-cause mortality, and subdistribution hazards models for cause-specific mortality. In total, 1906 patients were followed up for a median of 9.2 years. Conditional on surviving 2 years, the 10-year overall survival was 45%. The 10-year cumulative incidence of myeloma- and non-myeloma-related mortality was 33% and 13%, respectively. Multivariable analysis showed declining MM-specific mortality (subdistribution hazard ratio [SHR]_2000-2005 = 0.80, 95% confidence interval [CI], 0.60-1.07; SHR_2006-2014 = 0.46, 95% CI, 0.34-0.62; referent group: <2000), infection-related mortality (SHR_2000-2005 = 0.50, 95% CI, 0.29-0.85; SHR_2006-2014 = 0.35, 95%CI 0.21-0.60; referent group: <2000) and cardiovascular disease-related mortality (SHR_2000-2005 = 0.45, 95% CI 0.20-0.99; SHR_2006-2014 = 0.41, 95% CI 0.18-0.93; referent group: <2000). Although primary disease remains the major cause of late mortality, we observed a significant temporal decline in myeloma-, infection-, and cardiac-related late mortality over the past 25 years.

Project description:ImportanceThe past 4 decades have seen substantial changes in allogeneic blood or marrow transplantation (BMT) practice, with the overarching goal of expanding the eligible patient pool while optimizing disease-free survival.ObjectiveTo determine trends in life expectancy and cause-specific late mortality after allogeneic BMT performed over a 40-year period.Design, setting, and participantsA retrospective cohort study of 4741 individuals who lived 2 or more years after allogeneic BMT performed between January 1, 1974, and December 31, 2014, was conducted at City of Hope, University of Minnesota, or University of Alabama at Birmingham. The end of follow-up was March 23, 2020.ExposuresAllogeneic BMT performed in 3 eras: 1974-1989, 1990-2004, and 2005-2014.Main outcomes and measuresAll-cause, recurrence-related, and nonrecurrence-related mortality and projected reduction in life expectancy. Information regarding vital status and cause of death was obtained from the National Death Index Plus and Accurint databases.ResultsOf the 4741 individuals included in the study, 2735 (57.7%) were male; median age at BMT was 33 years (range, 0-75 years). The cumulative incidence of recurrence-related mortality plateaued at 10 years, reaching 12.2% (95% CI, 11.0%-13.4%) at 30 years from BMT. In contrast, the incidence of nonrecurrence-related mortality continued to increase and was 22.3% (95% CI, 20.4%-24.3%) at 30 years. Leading causes of nonrecurrence-related mortality included infection (30-year cumulative incidence, 10.7%; standardized mortality ratio [SMR], 52.0), subsequent malignant neoplasms (30-year cumulative incidence, 7.0%; SMR, 4.8), cardiovascular disease (30-year cumulative incidence, 4.6%; SMR, 4.1), and pulmonary disease (30-year cumulative incidence, 2.7%; SMR, 13.9). Compared with the general population, the relative mortality remained higher at 30 or more years after BMT (SMR, 5.4; 95% CI, 4.0-7.1). The cohort experienced a 20.8% reduction in life expectancy (8.7 years of life lost). Compared with 1974-1989 (reference), the adjusted 10-year hazard ratio (HR) of all-cause mortality declined over the 3 eras (1990-2004: HR, 0.67; 95% CI, 0.53-0.85; 2005-2014: HR, 0.52; 95% CI, 0.39-0.69; P < .001 for trend), as did years of life lost (1974-1989: 9.9 years [reference]; 1990-2004: 6.5 years; and 2005-2014: 4.2 years). The reduction in late mortality was most pronounced among individuals who underwent transplantation at ages younger than 18 years (1990-2004: HR, 0.62; 95% CI, 0.40-0.96; 2005-2014: HR, 0.30; 95% CI, 0.16-0.54; reference: 1974-1989; P < .001 for trend) and those who received bone marrow (1990-2004: HR, 0.70; 95% CI, 0.54-0.90; 2005-2014: HR, 0.45; 95% CI, 0.29-0.69; reference: 1974-1989; P < .001 for trend).Conclusions and relevanceThis cohort study noted that late mortality among recipients of allogeneic BMT has decreased over the past 40 years; however, life expectancy was not restored to expected rates compared with the general US population. Furthermore, the reduction in risk of late mortality appeared to be confined to those who underwent transplantation at a younger age or those who received bone marrow. Further efforts to mitigate disease recurrence, infections, subsequent neoplasms, cardiovascular disease, and pulmonary disease may be useful in this population.

Project description:BackgroundBlood or marrow transplantation (BMT) survivors carry a high burden of morbidity, yet health care utilization by this vulnerable population remains understudied. Patterns and predictors of various domains of health care utilization in long-term BMT survivors were evaluated.MethodsStudy participants were drawn from the Bone Marrow Transplant Survivor Study (BMTSS). Patients transplanted between 1974 and 2014 at one of three transplant centers who had survived ≥2 years after BMT and were aged ≥18 years at the time of the study were included. A BMTSS survey served as the source of data for health care utilization, sociodemographics, and chronic health conditions. Domains of health care utilization in the 2 years preceding study participation included routine checkups, BMT-related visits, transplant/cancer center visits, emergency room (ER) visits, hospitalizations, and high health care utilization (≥7 physician visits during the 2 years before the study). Clinical characteristics and therapeutic exposures were abstracted from medical records.ResultsIn this cohort of 3342 BMT survivors (52% allogeneic), the prevalence of health care utilization declined over time since BMT for both allogeneic and autologous BMT survivors, such that among those who had survived ≥20 years, only 49%-53% had undergone routine checkups, 37%-38% reported BMT-related visits, and 28%-29% reported transplant/cancer center visits. The presence of severe/life-threatening conditions and chronic graft-vs-host disease increased the odds of health care utilization across all domains. Lower education, lack of insurance, and Hispanic ethnicity were associated with a lower prevalence of routine checkups and/or transplant/cancer center visits. Lower income increased the odds of ER visits but reduced the odds of hospitalizations or high health care utilization.ConclusionsThis study identified vulnerable populations of long-term BMT survivors who would benefit from specialized risk-based anticipatory care to reduce high health care utilization, ER visits, and hospitalizations.

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

Project description:BackgroundLate mortality was investigated in patients with chronic myelogenous leukemia (CML) who underwent blood or bone marrow transplant (BMT) with or without prior tyrosine kinase inhibitor (TKI) therapy.MethodsBy using data from the Blood or Marrow Transplant Survivor Study, the authors examined late mortality in 447 patients with CML who underwent BMT between 1974 and 2010, conditional on surviving ≥2 years post-BMT. For vital status information, the medical records, the National Death Index, and the Accurint database were used. Standardized mortality ratios (SMRs) were calculated using general population age-specific, sex-specific, and calendar-specific mortality rates. Kaplan-Meier techniques and Cox regression were used for all-cause mortality analyses. Cumulative incidence and proportional subdistribution hazards models for competing risks were used for cause-specific mortality analyses.ResultsThe 10-year overall survival rate was 65.7% and 73% for those who underwent transplant with and without pre-BMT exposure to TKI therapy, respectively. Patients who underwent transplant with and without pre-BMT TKI experienced SMRs of 6.4 and 6.4, respectively (P = .8); and the SMRs were 11.6 and 8.1, respectively, for those with high-risk disease (P = .2). Independent predictors of non-CML-related mortality included chronic graft-versus-host disease (hazard ratio [HR], 2.8; 95% CI, 1.8-4.4) and busulfan/cyclophosphamide conditioning (HR, 0.5; 95% CI, 0.3-0.9; reference, total body irradiation/cyclophosphamide conditioning). The 20-year cumulative incidence of CML-related and non-CML-related mortality was 6% and 36%, respectively, for the entire cohort. Both CML-related mortality (HR, 1.0; 95% CI, 0.1-12.6) and non-CML-related mortality (HR, 1.3; 95% CI, 0.6-3.1) were comparable for those with and without pre-BMT TKI therapy.ConclusionsThe similar late mortality experienced by patients with CML who undergo transplantation with or without pre-BMT TKIs suggests that allogeneic BMT can be considered in the context of TKI intolerance or nonadherence. The prevention of post-BMT non-CML-related mortality could favorably affect long-term survival.
