572 Background: Single-center observational studies have established the use of single or tandem SCT to salvage relapsed GCT but randomized trials are lacking. We analyzed outcomes and prognostic factors in 2,395 male SCT recipients for relapsed GCT between 1990 and 2015. Methods: Recipients of single or tandem SCT reported to the Center for International Blood and Marrow Transplant Research were identified. Outcomes were compared by SCT year: 1990-94 (N = 288), 1995-99 (N = 351), 2000-04 (N = 376), 2005-09 (N = 509) and 2010-15 (N = 871). A recent subset (n = 267, 2000-2015) with detailed disease- and transplant-related data was further analyzed with a multivariate (MVA) Cox proportional hazards model. Results: Median age at SCT was 31 (11-76) years and 49% received SCT within 12 months of diagnosis consistent with early relapse/primary refractory GCT. 26% had primary extragonadal GCT; 1,167 (49%) had intent to tandem transplant (TT). The median follow up was 51 (3-313) months. Day 100 non-relapse mortality was statistically similar at 8% in 1990-94 (vs. 4% in 2010-15) but 3-year progression-free survival (PFS) improved from 24 (18-31)% in 1990-94 to 47 (43-50)% in 2010-15 (p < 0.0001) and 3-year survival (OS) from 35 (29-40)% to 54 (50-57)% in 2010-15 (p < 0.0001). Compared with single SCT, TT recipients were younger 31 (16-62) vs 34 (13-76), with lower Hematopoietic Cell Transplantation-Comorbidity Index, more likely to undergo SCT after 1 line of chemotherapy (28% vs 9%), and within 1 year of diagnosis (51% vs 38%). TT was preferred over single SCT over time (48% of SCT were TT in 2000-04 vs. 81% in 2010-15). In MVA, non-seminoma histology, residual tumor at SCT, receipt of > 1 line of pre-SCT chemotherapy and single SCT (vs. TT), were associated with worse PFS and OS. Year of SCT was not significant when adjusted for these covariates. Conclusions: In this large longitudinal cohort, improvements in PFS and OS were observed in recent years. SCT earlier in disease course and tandem SCT were associated with superior outcomes. These data involving a large cohort reported from 225 centers confirm specialized centers’ date in a real-world setting.

ObjectivesLeft ventricular (LV) septal hypertrophy in aortic stenosis raises diagnostic and therapeutic questions. However, the etiology and clinical consequences of this finding have not been well studied. The aim of this study was to perform a morphologic evaluation of the LV in aortic stenosis and to investigate the contributing factors and consequences of septal hypertrophy.MethodsPatients with moderate or severe aortic stenosis were prospectively enrolled. Patients with previous myocardial infarction, wall motion abnormalities, at least moderate valvular regurgitation, known cardiomyopathy, an LV ejection fraction of less than 50%, and age younger than 65 years were excluded.ResultsForty‐one patients underwent a final analysis. Septal hypertrophy (LV septal wall thickness ≥15 mm) was confirmed in 21 of 41 patients. The septal hypertrophy group had higher peak aortic valve velocity, a higher diabetes mellitus rate, and a higher rate and longer duration of hypertension than those without septal hypertrophy. The peak aortic valve velocity (odds ratio, 7.1; 95% confidence interval, 1.4–37.1) and diabetes mellitus (odds ratio, 7.4; 95% confidence interval, 1.2–46.2) were the significant factors associated with septal hypertrophy by multivariate analysis. Intraventricular conduction disturbance on electrocardiography was more frequent in the septal hypertrophy group (P = .021).ConclusionsLeft ventricular septal hypertrophy was commonly observed in elderly patients with aortic stenosis, and a higher aortic valve velocity, hypertension, and diabetes mellitus were associated factors. Intraventricular conduction disturbance occurred more often in patients with septal hypertrophy than those without, which implies the pathophysiologic consequence. Further studies are needed to determine the impact of septal hypertrophy and intraventricular conduction disturbance on the prognosis of patients after aortic valve interventions.

SummaryThe oral proteasome inhibitor ixazomib is approved in the United States, European Union and other countries, in combination with oral lenalidomide and dexamethasone (Rd), for the treatment of patients with multiple myeloma who have received at least one prior therapy. Approval was based on the global, randomised, double‐blind, placebo‐controlled Phase III TOURMALINE‐MM1 study of ixazomib‐Rd (IRd) versus placebo‐Rd in patients with relapsed/refractory multiple myeloma. IRd resulted in a significant improvement in progression‐free survival versus placebo‐Rd (median: 20·6 vs. 14·7 months; hazard ratio 0·74). Common toxicities observed more commonly with IRd versus placebo‐Rd were thrombocytopenia, nausea, vomiting, diarrhoea, constipation, rash, peripheral neuropathy, peripheral oedema and back pain; these were generally grade 1/2 in severity except for thrombocytopenia (19% vs. 9% grade 3/4), which appeared manageable and reversible, with no differences between arms in significant bleeding or dose discontinuations. No cumulative toxicities were observed, indicating the potential feasibility of long‐term IRd treatment. Safety data from TOURMALINE‐MM1 are reviewed and guidance for managing clinically relevant adverse events associated with IRd is provided. Most toxicities were manageable with supportive care and dose delays or reductions as needed. Clinicians should be aware of and understand these potential side effects to optimise and prolong patient benefit.

BACKGROUNDRace/ethnicity remains an important barrier in clinical care. The authors investigated differences in the receipt of autologous hematopoietic cell transplantation (AHCT) among patients with multiple myeloma (MM) and outcomes based on race/ethnicity in the United States.METHODSThe Center for International Blood and Marrow Transplant Research database was used to identify 28,450 patients who underwent AHCT for MM from 2008 through 2014. By using data from the National Cancer Institute's Surveillance, Epidemiology, and End Results 18 registries, the incidence of MM was calculated, and a stem cell transplantation utilization rate (STUR) was derived. Post‐AHCT outcomes were analyzed among patients ages 18 to 75 years who underwent melphalan‐conditioned peripheral cell grafts (N = 24,102).RESULTSThe STUR increased across all groups from 2008 to 2014. The increase was substantially lower among Hispanics (range, 8.6%‐16.9%) and non‐Hispanic blacks (range, 12.2%‐20.5%) compared with non‐Hispanic whites (range, 22.6%‐37.8%). There were 18,046 non‐Hispanic whites, 4123 non‐Hispanic blacks, and 1933 Hispanic patients. The Hispanic group was younger (P < .001). Fewer patients older than 60 years underwent transplantation among Hispanics (39%) and non‐Hispanic blacks (42%) compared with non‐Hispanic whites (56%). A Karnofsky score <90% and a hematopoietic cell transplantation comorbidity index score >3 were more common in non‐Hispanic blacks compared with Hispanic and non‐Hispanic whites (P < .001). More Hispanics (57%) versus non‐Hispanic blacks (54%) and non‐Hispanic whites (52%; P < .001) had stage III disease. More Hispanics (48%) versus non‐Hispanic blacks (45%) and non‐Hispanic whites (44%) had a very good partial response or better before transplantation (P = .005). Race/ethnicity did not impact post‐AHCT outcomes.CONCLUSIONSAlthough the STUR increased, it remained low and was significantly lower among Hispanics followed by non‐Hispanic blacks compared with non‐Hispanic whites. Race/ethnicity did not impact transplantation outcomes. Efforts to increase the rates of transplantation for eligible patients who have MM, with an emphasis on groups that underuse transplantation, are warranted.

Purpose: To evaluate the safety of single intravitreal 2 mg ziv-aflibercept (0.08 mL) injections for the treatment of choroidal neovascular membranes (CNVM). Methods: Eyes with choroidal neovascular membranes because of several conditions each received single intravitreal injections of 2 mg ziv-aflibercept (0.08 mL). Comprehensive ophthalmic examinations and detailed systemic evaluations were performed at baseline and Days 1, 7, and 30 after injections. Standard electroretinography was performed at baseline and Day 30. Primary outcome measures consisted of safety assessments (signs of clinical toxicity and electroretinographic abnormalities). Secondary outcome measures included changes in best-corrected visual acuity (BCVA) and central subfield thickness (CST) of the macula. Results: Twenty-one eyes of 20 patients (12 males) received injections. Etiologies responsible for the choroidal neovascular membranes included age-related macular degeneration (14), polypoidal choroidal vasculopathy (PCV) (3), myopia (2), and idiopathic juxtafoveal telangiectasia (2). None of the patients complained of worsening vision or pain after the intravitreal injections and no intraocular inflammation was seen. No significant changes in the electroretinographic b/a ratio from baseline to 1 month were measured (scotopic: P = 0.89; photopic: P = 0.13) and mean intraocular pressures were unchanged (14.2 ± 3.6 vs. 13.7 ± 3.0 mmHg; P = 0.62). Mean best-corrected visual acuity did not change significantly from baseline to 1 month (0.66 ± 0.37 logMAR [Snellen equivalent: 20/100] vs. 0.61 ± 0.35 logMAR [Snellen equivalent: 20/80]; P = 0.72) but significant improvements in central subfield thickness were seen (343 ± 177 vs. 210 ± 133 μ m; P = 0.01). Conclusion: Single intravitreal injections of 2 mg ziv-aflibercept (0.08 mL) appear to be safe through 1 month.
