  • Bortezomib-Based Induction Is Associated with Superior Outcomes in Light Chain Amyloidosis Patients Treated with Autologous Hematopoietic Cell Transplantation Regardless of Plasma Cell Burden

    • The benefits of pre-transplant induction chemotherapy in light chain (AL) amyloidosis, a low burden plasma cell (PC) neoplasm associated with multiorgan dysfunction, is debatable, although with the availability of bortezomib, this approach is being increasingly pursued. We analyzed the outcomes of AL amyloidosis patients undergoing autologous hematopoietic cell transplant between 2014 and 2018 that were reported to the Center for International Blood and Marrow Transplant Research database. Of 440 patients, 294 received bortezomib-based induction, and 146 received no induction. Patients receiving induction had greater PC burden compared to no induction (PC 10% or more, 39% versus 11%; P < .01). At 2 years, the induction group compared to no induction had lower relapse/progression: 13% (9% to 18%) versus 23% (16% to 32%) (P = .02); better progression-free survival (PFS): 82% (77% to 87%) versus 69% (61% to 77%) (P < .01); and similar overall survival (OS): 92% (88% to 95%) versus 89% (84% to 94%) (P = .22), findings that were confirmed on multivariate analysis. A subset analysis limited to patientswith <10% PC also showed superior relapse/progression (hazard ratio [HR],.43; 95% confidence interval [CI],.24 to.78; P < .01) and PFS (HR,.43; 95% CI,.26 to .72; P < .01) for induction compared to no induction. Thus, we conclude that pre-transplant bortezomib-based induction was associated with improved relapse/progression and PFS in AL amyloidosis. Longer survival follow-up is warranted, as OS was excellent in both cohorts at 2 years.

  • Hematopoietic cell transplantation utilization and outcomes for primary plasma cell leukemia in the current era
  • 2020
  • Ingår i: Leukemia. - : SPRINGERNATURE. - 0887-6924 .- 1476-5551. ; 34:12, s. 3338-3347

    • The outcomes of patients with primary plasma cell leukemia (pPCL) after undergoing hematopoietic cell transplantation (HCT) in the novel agent era are unknown. We report outcomes of 348 patients with pPCL receiving autologous (auto-) HCT (n = 277) and allogeneic (allo-) HCT (n = 71) between 2008 and 2015. Median age was 60 years and 56 years for auto- and allo-HCT respectively. For auto-HCT, the 4-year outcomes were: non-relapse mortality (NRM) 7% (4-11%), relapse (REL) 76% (69-82%), progression-free survival (PFS) 17% (13-23%), and overall survival (OS) 28% (22-35%). Karnofsky performance status (KPS) > 90 and >= very good partial response (VGPR) predicted superior OS in multi-variate analysis for auto-HCT. For allo-HCT, the 4-year outcomes were: NRM 12% (5-21%), REL 69% (56-81%), PFS 19% (10-31%), and OS 31% (19-44%). Compared with prior CIBMTR pPCL patients (1995-2006), inferior survival was noted in the current cohort (3-year OS, 39% vs. 38% in allo-HCT, and 62% vs. 35% in auto-HCT) respectively. However, we noted an increased HCT utilization, from 12% (7-21%) in 1995 to 46% (34-64%) in 2009 using SEER data (available till 2009). Despite modern induction translating to higher proportion receiving HCT, the outcomes remain poor in pPCL patients, mainly derived by high relapse rates post-HCT.

  • Age no bar : A CIBMTR analysis of elderly patients undergoing autologous hematopoietic cell transplantation for multiple myeloma
  • 2020

    • Background Upfront autologous hematopoietic stem cell transplantation (AHCT) remains an important therapy in the management of patients with multiple myeloma (MM), a disease of older adults. Methods The authors investigated the outcomes of AHCT in patients with MM who were aged >= 70 years. The Center for International Blood and Marrow Transplant Research (CIBMTR) database registered 15,999 patients with MM in the United States within 12 months of diagnosis during 2013 through 2017; a total of 2092 patients were aged >= 70 years. Nonrecurrence mortality (NRM), disease recurrence and/or progression (relapse; REL), progression-free survival (PFS), and overall survival (OS) were modeled using Cox proportional hazards models with age at transplantation as the main effect. Because of the large sample size, aPvalue <.01 was considered to be statistically significant a priori. Results An increase in AHCT was noted in 2017 (28%) compared with 2013 (15%) among patients aged >= 70 years. Although approximately 82% of patients received melphalan (Mel) at a dose of 200 mg/m(2)overall, 58% of the patients aged >= 70 years received Mel at a dose of 140 mg/m(2). On multivariate analysis, patients aged >= 70 years demonstrated no difference with regard to NRM (hazard ratio [HR] 1.3; 99% confidence interval [99% CI], 1-1.7 [P = .06]), REL (HR, 1.03; 99% CI, 0.9-1.1 [P = 0.6]), PFS (HR, 1.06; 99% CI, 1-1.2 [P = 0.2]), and OS (HR, 1.2; 99% CI, 1-1.4 [P = .02]) compared with the reference group (those aged 60-69 years). In patients aged >= 70 years, Mel administered at a dose of 140 mg/m(2)was found to be associated with worse outcomes compared with Mel administered at a dose of 200 mg/m(2), including day 100 NRM (1% [95% CI, 1%-2%] vs 0% [95% CI, 0%-1%];P = .003]), 2-year PFS (64% [95% CI, 60%-67%] vs 69% [95% CI, 66%-73%];P = .003), and 2-year OS (85% [95% CI, 82%-87%] vs 89% [95% CI, 86%-91%];P = .01]), likely representing frailty. Conclusions The results of the current study demonstrated that AHCT remains an effective consolidation therapy among patients with MM across all age groups.
