The use of opioids and/or benzodiazepines in older adults (65 y+) who received an allogeneic hematopoietic cell transplant (HCT) is not known. In March 2016, the CDC released its strongest guidelines against prescription of opioids and co-prescription of opioids + benzodiazepines. We evaluated the use of opioids and/or benzodiazepines in older (65 y + , n = 114) vs. younger (40-64 y, n = 240) allogeneic-HCT recipients before and after the CDC guidelines. The proportion of patients with >10-days of use of opioids and/or benzodiazepines peri-HCT (day-14 to +28) was compared. Opioids: the older (65 + y) group had similar odds of receiving opioids as the younger group (40-64 y) [O.R. 0.7 (95%CI:0.4-1.2)]. Those transplanted after the CDC guideline had 0.4 (95%CI:0.2-0.7) times the odds of receiving opioids. Benzodiazepines: The older (65 + y) group was 0.6 times (95%CI:0.3-0.9) as likely to receive benzodiazepines. There was no significant change in benzodiazepines use after the CDC guideline. Opioids + Benzodiazepines: The older group (65 + y) was 0.5 (95%CI:0.3-0.9) times as likely to receive both opioids+benzodiazepines. There was no significant change in opioids+benzodiazepines use after the CDC guideline. Though we observed a significant decrease in use of opioids after the CDC guideline, the use of benzodiazepines and combined opioids+benzodiazepines remained constant. Older recipients (65 + y) received less opioids, benzodiazepines, and combined opioids+benzodiazepines., (© 2022. The Author(s), under exclusive licence to Springer Nature Limited.)

Acute Myeloid Leukemia (AML) has a median age at diagnosis of 67 years. The most common curative therapy remains an allogeneic hematopoietic stem cell transplantation (HCT), yet it is complicated by treatment-related mortality (TRM) and ongoing morbidity including graft versus host disease (GVHD) that may impact survival, particularly in older patients. We examined the outcomes and predictors of success in 1321 patients aged 60 years and older receiving a HCT for AML in first complete remission (CR1) from 2007-2017 and reported to the CIBMTR. Outcomes were compared in three age cohorts (60-64; 65-69; 70+). With median follow-up of nearly 3 years, patients aged 60-64 had modestly, though significantly better OS, DFS and lower TRM than those either 65-69 or 70+; cohorts with similar outcomes. Three-year OS for the 3 cohorts was 49.4%, 42.3%, and 44.7% respectively (p = 0.026). TRM was higher with increasing age, cord blood as graft source and HCT-CI score of ≥3. Conditioning intensity was not a significant predictor of OS in the 60-69 cohort with 3-year OS of 46% for RIC and 49% for MAC (p = 0.38); MAC was rarely used over age 70. There was no difference in the relapse rate, incidence of Grade III/IV acute GVHD, or moderate-severe chronic GVHD across the age cohorts. After adjusting for other predictors, age had a small effect on OS and TRM. High-risk features including poor cytogenetics and measurable residual disease (MRD) prior to HCT were each significantly associated with relapse and accounted for most of the adverse impact on OS and DFS. Age did not influence the incidence of either acute or chronic GVHD; while graft type and associated GVHD prophylaxis were most important. These data suggest that age alone is not a barrier to successful HCT for AML in CR1 and should not exclude patients from HCT. Efforts should focus on minimizing residual disease and better donor selection., (© 2022. The Author(s), under exclusive licence to Springer Nature Limited.)

Chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic cell transplantation (HCT) requires prolonged immunosuppressive therapy (IST), often requiring slow tapering with patients experiencing cGVHD flares and treatment failure. In 145 adult recipients developing cGVHD after matched sibling or umbilical cord blood donor HCT from 2010 to 2018, 2-year cumulative incidence of flares after cGVHD diagnosis was estimated at 60% (95% CI, 51-70%), with median time-to-first flare of 188 days (range, 16-751). Of 88 patients experiencing a flare, 32 (36%) had multiple flares (range, 2-4). First flare treatment consisted of an increase in prednisone dose in 77 patients (88%), plus topical therapy in 8 (9%) or another systemic IST in 43 patients (49%). Higher flare risk was associated with quiescent type of cGVHD at onset (HR 1.8; 95% CI: 1.1-2.7; p = 0.04). Patients without a flare required a shorter duration of IST and were more likely to achieve a durable discontinuation of systemic IST (86% vs. 31% for ≥6 consecutive months). Flares were associated with protective effect on relapse (HR 0.2, 95% CI: 0.1-0.3), however not with worsened 2-year NRM or OS. Flares of cGVHD identify a group needing better approaches to limit the duration of IST and thus the morbidity of cGVHD., (© 2022. The Author(s), under exclusive licence to Springer Nature Limited.)

We compared chronic graft-versus-host disease (cGvHD) following umbilical cord blood (UCBT) and matched sibling donor peripheral blood transplant (MSD). 145 patients (2010-2017) with cGvHD after MSD (n = 104) and UCBT (n = 41) were included. Prior acute GvHD was less frequent in MSD (55% vs. 85%; p = 0.01). Severe cGvHD (32% vs. 15%, p = 0.01) and de-novo onset (45% vs. 15%, p < 0.01) were more frequent following MSD. Liver was more frequently involved in MSD recipients (38% vs. 6%); and GI in UCBT (33% vs. 63%), both p < 0.01. Overall response (CR + PR) was similar between both cohorts. 2-year CR was higher in UCBT (14% vs 33%, p = 0.02). Karnofsky score (KPS) ≥ 90 at cGvHD diagnosis was associated with higher odds of response (95%CI: 1.42-10, p < 0.01). The cumulative incidence of durable discontinuation of immune-suppressive therapy, failure-free survival (FFS) and NRM at 2-years were similar between cohorts. KPS < 90 (95%CI: 3.1-24.9, p < 0.01) and platelets <100 × 10e9/L (95%CI: 1.25-10, p = 0.01) were associated with higher risk of NRM. UCBT patients were more likely to have a prior acute GvHD, less severe cGvHD and more likely to attain CR. Despite differences, both cohorts had similar NRM and FFS. High-risk groups, including those with platelets <100 × 10e9/L and KPS < 90, need careful monitoring and intensified therapy.
