Burden of morbidity in 10+ year survivors of hematopoietic cell transplantation: report from the bone marrow transplantation survivor study.

ABSTRACT: Long-term morbidity after hematopoietic cell transplantation (HCT) is unknown. The risk of physical and psychological health in 324 patients who had survived 10 or more years after HCT and a sibling comparison group (n = 309) was evaluated. Using the Common Terminology Criteria for Adverse Events, the 15-year cumulative incidence of severe/life-threatening/fatal conditions was 41% (95% confidence interval, 34% to 48%). HCT survivors were 5.7 times as likely to develop a severe/life-threatening condition (P < .001) and 2.7 times as likely to report somatic distress (P < .001) compared with siblings. Compared with allogeneic HCT recipients with no chronic graft-versus-host disease (GVHD), those with active chronic GVHD were at a 1.8-fold higher risk of severe/life-threatening health conditions (P = .006) and a 4.5-fold higher risk of somatic distress (P = .04); allogeneic HCT recipients with resolved chronic GVHD were not at increased risk of morbidity compared with those with no chronic GVHD. Only 27% of the HCT survivors returned to the transplantation center for their cancer-related care. The burden of long-term physical and emotional morbidity borne by survivors remains substantial, even beyond 10 years after HCT; however, specialized health care is underused. Patients, families, and healthcare providers need to be made aware of the high burden, so they can plan for post-HCT care, even many years after HCT.

Project description:Frailty results in decreased physiological reserve and diminished resistance to stressors; approximately 10% of those in the elderly population (those ?65 years) are frail. High-intensity treatments and complications after hematopoietic cell transplantation (HCT) injure normal tissues and may increase the risk of frailty even among nongeriatric HCT patients.To determine the prevalence of frailty in young adult HCT patients (18- to 64-year-olds) and siblings; and the impact of frailty on subsequent mortality in HCT survivors.This cohort study, conducted in August 2015 examined 998 HCT survivors, who underwent transplant procedures between 1974 and 1998, who have survived at least 2 years after HCT, and 297 frequency-matched siblings. The study was performed at City of Hope or University of Minnesota with participants completing surveys at home or in the clinic. Hematopoietic cell transplantation survivors and siblings participating in the Bone Marrow Transplant Survivor Study (BMTSS) completed a frailty survey between February 13, 1999 and June 15, 2005 (median time since HCT: 7.9 years); HCT survivors were followed for subsequent mortality (median: 10.3 years from survey).Prevalence and predictors of frailty; impact of frailty on subsequent mortality in HCT survivors. Frailty phenotype defined as exhibiting 3 or more of the following characteristics: clinically underweight, exhaustion, low energy expenditure, slow walking speed, and muscle weakness. The national Death Index, Social Security Death Index and medical records were used for mortality assessment as of December 21, 2011.The 998 HCT survivors were a mean (SD) of 42.5 (11.6) years of age, and the 297 matched siblings were 43.8 (10.9) years of age. The prevalence of frailty among young adult HCT patients exceeded 8%. The HCT survivors were 8.4 times more likely to be frail than their siblings (95% CI, 2.0-34.5; P?=?.003). Among HCT recipients, allogeneic HCT recipients with chronic graft-vs-host disease (GvHD) were at increased risk of frailty compared with autologous HCT (OR,15.02; 95% CI, 6.6-34.3; P?<?.001); resolved chronic GvHD (OR, 2.7; 95% CI, 1.1-6.9; P?=?.04). Cumulative incidence of subsequent all-cause mortality was 39.3% and 14.7% at 10 years for HCT recipients with and without frailty, respectively (P?<?.001). Frailty was associated with a 2.76-fold (95% CI, 1.7-4.4; P?<?.001) increased risk of subsequent mortality after adjusting for relevant prognosticators.The prevalence of frailty among young-adult HCT survivors approaches that seen in the elderly general population. Frail HCT survivors are at increased risk of subsequent mortality when compared with nonfrail survivors. This study identifies vulnerable populations needing close monitoring to anticipate and manage morbidity and prevent mortality.

Project description:In the coronavirus disease 19 (COVID-19) pandemic era, the number of haploidentical hematopoietic cell transplantations (HCTs) with peripheral blood (PB) grafts increased significantly compared with HCTs with bone marrow (BM) grafts, which may be associated with adverse outcomes. We compared outcomes of HCT in BM graft and PB graft recipients age ≥18 years with hematologic malignancies who underwent T cell- replete haploidentical HCT and received graft-versus-host disease (GVHD) prophylaxis with post-transplantation cyclophosphamide, tacrolimus, and mycophenolate mofetil. Among the 264 patients, 180 (68%) received a BM graft and 84 (32%) received a PB graft. The median patient age was 50 years in both groups. The majority (n = 199; 75%) received reduced-intensity conditioning. The rate of acute leukemia or myelodysplastic syndrome was higher in the BM graft recipients compared with the PB graft recipients (85% [n = 152] versus 55% [n = 46]; P < .01). The median times to neutrophil and platelet engraftment and the incidence of grade II-IV and grade III-IV acute GVHD (aGVHD) were comparable in the 2 groups. Among the patients with grade II-IV aGVHD, the rate of steroid-refractory aGVHD was 9% (95% confidence interval [CI], 5% to 18%) in the BM group versus 32% (95% CI, 19% to 54%) in the PB group (hazard ratio [HR], 3.7, 95% CI, 1.5 to 9.3; P = .006). At 1 year post-HCT, the rate of chronic GVHD (cGVHD) was 8% (95% CI, 4% to 13%) in the BM group versus 22% (95% CI, 14% to 36%) in the PB group (HR, 3.0; 95% CI, 1.4-6.6; P = .005), and the rate of systemic therapy-requiring cGVHD was 2.5% (95% CI, 1% to 7%) versus 14% (95% CI, 7% to 27%), respectively (HR, 5.6; 95% CI, 1.7 to 18; P = .004). The PB group had a significantly higher risk of bacterial and viral infections, with no appreciable advantage in the duration of hospitalization, immune reconstitution, relapse, nonrelapse mortality, or survival. Our data suggest a benefit of the use of BM grafts over PB grafts for haplo-HCT.

Project description:BackgroundAllogeneic hematopoietic stem cell transplantation (AHSCT) is a curative therapeutic approach for different hematological malignancies (HMs), and epigenetic modifications, including DNA methylation, play a role in the reconstitution of the hematopoietic system after AHSCT. This study aimed to explore global DNA methylation dynamic of bone marrow (BM) hematopoietic stem and progenitor cells (HSPCs) from donors and their respective recipients affected by acute myeloid leukemia (AML), acute lymphoid leukemia (ALL) and Hodgkin lymphoma (HL) during the first year after transplant.MethodsWe measured DNA methylation profile by Illumina HumanMethylationEPIC in BM HSPC of 10 donors (t0) and their matched recipients at different time points after AHSCT, at day + 30 (t1), + 60 (t2), + 120 (t3), + 180 (t4), and + 365 (t5). Differential methylation analysis was performed by using R software and CRAN/Bioconductor packages. Gene set enrichment analysis was carried out on promoter area of significantly differentially methylated genes by clusterProfiler package and the mSigDB genes sets.ResultsResults show significant differences in the global methylation profile between HL and acute leukemias, and between patients with mixed and complete chimerism, with a strong methylation change, with prevailing hyper-methylation, occurring 30 days after AHSCT. Functional analysis of promoter methylation changes identified genes involved in hematopoietic cell activation, differentiation, shaping, and movement. This could be a consequence of donor cell "adaptation" in recipient BM niche. Interestingly, this epigenetic remodeling was reversible, since methylation returns similar to that of donor HSPCs after 1 year. Only for a pool of genes, mainly involved in dynamic shaping and trafficking, the DNA methylation changes acquired after 30 days were maintained for up to 1 year post-transplant. Finally, preliminary data suggest that the methylation profile could be used as predictor of relapse in ALL.ConclusionsOverall, these data provide insights into the DNA methylation changes of HSPCs after transplantation and a new framework to investigate epigenetics of AHSCT and its outcomes.
