    • Non-graft-versus-host disease (GVHD) ocular complications are generally uncommon after hematopoietic cell transplantation (HCT) but can cause prolonged morbidity affecting activities of daily living and quality of life. Here we provide an expert review of non-GVHD ocular complications in a collaboration between transplantation physicians and ophthalmologists through the Late Effects and Quality of Life Working Committee of the Center for International Blood and Marrow Transplant Research and the Transplant Complications Working Party of the European Society of Blood and Marrow Transplantation. Complications discussed in this review include cataracts, glaucoma, ocular infections, ocular involvement with malignancy, ischemic microvascular retinopathy, central retinal vein occlusion, retinal hemorrhage, retinal detachment and ocular toxicities associated with medications. We summarize the incidence, risk factors, screening, prevention, and treatment of individual complications and generate evidence-based recommendations. Baseline ocular evaluation before HCT should be considered in all patients who undergo HCT. Follow-up evaluations should be considered according to clinical signs and symptoms and risk factors. Better preventive strategies and treatments remain to be investigated for individual ocular complications after HCT. Both transplantation physicians and ophthalmologists should be knowledgeable about nonGVHD ocular complications and provide comprehensive collaborative team care.

  • Pre-transplant marital status and hematopoietic cell transplantation outcomes
  • 2020
  • Ingår i: Current Oncology. - : MULTIMED INC. - 1198-0052 .- 1718-7729. ; 27:6, s. E596-E606

    • Background Evidence about the impact of marital status before hematopoietic cell transplantation (HCT) on outcomes after HCT is conflicting. Methods We identified patients 40 years of age and older within the Center for International Blood and Marrow Transplant Research registry who underwent HCT between January 2008 and December 2015. Marital status before HCT was declared as one of: married or living with a partner, single (never married), separated or divorced, and widowed. We performed a multivariable analysis to determine the association of marital status with outcomes after HCT. Results We identified 10,226 allogeneic and 5714 autologous HCT cases with, respectively, a median follow-up of 37 months (range: 1-102 months) and 40 months (range: 1-106 months). No association between marital status and overall survival was observed in either the allogeneic (p = 0.58) or autologous (p = 0.17) setting. However, marital status was associated with grades 2-4 acute graft-versus-host disease (GVHD), p < 0.001, and chronic GVHD, p = 0.04. The risk of grades 2-4 acute GVHD was increased in separated compared with married patients [hazard ratio (FIR): 1.13; 95% confidence interval (CI): 1.03 to 1.24], and single patients had a reduced risk of grades 2-4 acute GVHD (FIR: 0.87; 95% CI: 0.77 to 0.98). The risk of chronic GVHD was lower in widowed compared with married patients (FIR: 0.82; 95% CI: 0.67 to 0.99). Conclusions Overall survival after HCT is not influenced by marital status, but associations were evident between marital status and grades 2-4 acute and chronic GVHD. To better appreciate the effects of marital status and social support, future research should consider using validated scales to measure social support and patient and caregiver reports of caregiver commitment, and to assess health-related quality of life together with health care utilization.

  • Risk Factors for Graft-versus-Host Disease in Haploidentical Hematopoietic Cell Transplantation Using Post-Transplant Cyclophosphamide
  • 2020
  • Ingår i: Biology of blood and marrow transplantation. - 1083-8791 .- 1523-6536. ; 26:8, s. 1459-1468

    • Post-transplant cyclophosphamide (PTCy) has significantly increased the successful use of haploidentical donors with a relatively low incidence of graft-versus-host disease (GVHD). Given its increasing use, we sought to determine risk factors for GVHD after haploidentical hematopoietic cell transplantation (haplo-HCT) using PTCy. Data from the Center for International Blood and Marrow Transplant Research on adult patients with acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or chronic myeloid leukemia who underwent PTCy-based haplo-HCT (2013 to 2016) were analyzed and categorized into 4 groups based on myeloablative (MA) or reduced-intensity conditioning (RIC) and bone marrow (BM) or peripheral blood (PB) graft source. In total, 646 patients were identified (MA-BM = 79, MA-PB = 183, RIC-BM = 192, RIC-PB = 192). The incidence of grade 2 to 4 acute GVHD at 6 months was highest in MA-PB (44%), followed by RIC-PB (36%), MA-BM (36%), and RIC-BM (30%) (P = .002). The incidence of chronic GVHD at 1 year was 40%, 34%, 24%, and 20%, respectively (P < .001). In multivariable analysis, there was no impact of stem cell source or conditioning regimen on grade 2 to 4 acute GVHD; however, older donor age (30 to 49 versus <29 years) was significantly associated with higher rates of grade 2 to 4 acute GVHD (hazard ratio [HR], 1.53; 95% confidence interval [CI], 1.11 to 2.12; P = .01). In contrast, PB compared to BM as a stem cell source was a significant risk factor for the development of chronic GVHD (HR, 1.70; 95% CI, 1.11 to 2.62; P = .01) in the RIC setting. There were no differences in relapse or overall survival between groups. Donor age and graft source are risk factors for acute and chronic GVHD, respectively, after PTCy-based haplo-HCT. Our results indicate that in RIC haplo-HCT, the risk of chronic GVHD is higher with PB stem cells, without any difference in relapse or overall survival.

  • Risk of acute myeloid leukemia and myelodysplastic syndrome after autotransplants for lymphomas and plasma cell myeloma
  • 2018
  • Ingår i: Leukemia research. - 0145-2126 .- 1873-5835. ; 74, s. 130-136
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Exposures to DNA-damaging drugs and ionizing radiations increase risks of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS).Methods: 9028 recipients of hematopoietic cell autotransplants (1995-2010) for Hodgkin lymphoma (HL; n=916), non-Hodgkin lymphoma (NHL; n=3546) and plasma cell myeloma (PCM; n=4566), reported to the CIBMTR, were analyzed for risk of subsequent AML or MDS.Results: 335 MDS/ AML cases were diagnosed posttransplant (3.7%). Variables associated with an increased risk for AML or MDS in multivariate analyses were: (1) conditioning with total body radiation versus chemotherapy alone for HL (HR=4.0; 95% confidence interval [1.4, 11.6]) and NHL (HR=2.5 [1.1, 2.5]); (2) >= 3 versus 1 line of chemotherapy for NHL (HR=1.9 [1.3, 2.8]); and (3) subjects with NHL transplanted in 2005-2010 versus 1995-1999 (HR=2.1 [1.5, 3.1]). Using Surveillance, Epidemiology and End Results (SEER) data, we found risks for AML/ MDS in HL, NHL and PCM to be 5-10 times the background rate. In contrast, relative risks were 10-50 for AML and approximately 100 for MDS in the autotransplant cohort.Conclusions: There are substantial risks of AML and MDS after autotransplants for HL, NHL and PCM.

  • Prognostic Score and Cytogenetic Risk Classification for Chronic Lymphocytic Leukemia Patients : Center for International Blood and Marrow Transplant Research Report
  • 2019
  • Ingår i: Clinical Cancer Research. - : AMER ASSOC CANCER RESEARCH. - 1078-0432 .- 1557-3265. ; 25:16, s. 5143-5155

    • Purpose: To develop a prognostic model and cytogenetic risk classification for previously treated patients with chronic lymphocytic leukemia (CLL) undergoing reduced intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (HCT).Experimental Design: We performed a retrospective analysis of outcomes of 606 patients with CLL who underwent RIC allogeneic HCT between 2008 and 2014 reported to the Center for International Blood and Marrow Transplant Research.Results: On the basis of multivariable models, disease status, comorbidity index, lymphocyte count, and white blood cell count at HCT were selected for the development of prognostic model. Using the prognostic score, we stratified patients into low-, intermediate-, high-, and very-high-risk [4-year progression-free survival (PFS) 58%, 42%, 33%, and 25%, respectively, P < 0.0001; 4-year overall survival (OS) 70%, 57%, 54%, and 38%, respectively, P < 0.0001]. We also evaluated karyotypic abnormalities together with del(17p) and found that del(17p) or >= 5 abnormalities showed inferior PFS. Using a multivariable model, we classified cytogenetic risk into low, intermediate, and high (P < 0.0001). When the prognostic score and cytogenetic risk were combined, patients with low prognostic score and low cytogenetic risk had prolonged PFS (61% at 4 years) and OS (75% at 4 years).Conclusions: In this large cohort of patients with previously treated CLL who underwent RIC HCT, we developed a robust prognostic scoring system of HCT outcomes and a novel cytogenetic-based risk stratification system. These prognostic models can be used for counseling patients, comparing data across studies, and providing a benchmark for future interventions. For future study, we will further validate these models for patients receiving targeted therapies prior to HCT.

  • The Concentration of Total Nucleated Cells in Harvested Bone Marrow for Transplantation Has Decreased over Time
  • 2019
  • Ingår i: Biology of blood and marrow transplantation. - : ELSEVIER SCIENCE INC. - 1083-8791 .- 1523-6536. ; 25:7, s. 1325-1330

    • Bone marrow (BM) is an essential source of hematopoietic stem cell grafts for many allogeneic hematopoietic cell transplant (HCT) recipients, including adult patients (for specific diseases and transplantation strategies) and the majority of pediatric recipient. However, since the advent of granulocyte colony-stimulating factor-mobilized peripheral blood stem cell (PBSC) grafts, there has been a significant decrease in the use of BM in HCT, thought to be due mainly to the increased logistical challenges in harvesting BM compared with PBSCs, as well as generally no significant survival advantage of BM over PBSCs. The decreased frequency of collection has the potential to impact the quality of BM harvests. In this study, we examined >15,000 BM donations collected at National Marrow Donor Program centers between 1994 and 2016 and found a significant decline in the quality of BM products, as defined by the concentration of total nucleated cells (TNCs). The mean TNC concentration in BM donations dropped from 21.8 x 10(6) cells/mL in the earliest era (1994 to 1996) to 18.7 x 10(6) cells/mL in the most recent era (2012 to 2016) (means ratio,.83; P < .001). This decline in BM quality was seen despite the selection of more donors perceived to be optimal (eg, younger and male). Multivariate regression analysis showed that higher volume centers (performing >30 collections per era) had better-quality harvests with higher concentrations of TNCs collected. In conclusion, we have identified a significant decrease in the quality of BM collections over time, and lower-volume collection centers had poorer-quality harvests. In this analysis, we could not elucidate the direct cause for this finding, suggesting the need for further studies to investigate the key factors responsible and to explore the impact on transplant recipients.

  • Country-Level Macroeconomic Indicators Predict Early Post-Allogeneic Hematopoietic Cell Transplantation Survival in Acute Lymphoblastic Leukemia : A CIBMTR Analysis
  • 2018
  • Ingår i: Biology of blood and marrow transplantation. - : ELSEVIER SCIENCE INC. - 1083-8791 .- 1523-6536. ; 24:9, s. 1928-1935

    • For patients with acute lymphoblastic leukemia (ALL), allogeneic hematopoietic cell transplantation (alloHCT) offers a potential cure. Life-threatening complications can arise from alloHCT that require the application of sophisticated health care delivery. The impact of country-level economic conditions on post-transplantation outcomes is not known. Our objective was to assess whether these variables were associated with outcomes for patients transplanted for ALL. Using data from the Center for Blood and Marrow Transplant Research, we included 11,261 patients who received a first alloHCT for ALL from 303 centers across 38 countries between the years of 2005 and 2013. Cox regression models were constructed using the following macroeconomic indicators as main effects: Gross national income per capita, health expenditure per capita, and Human Development Index (HDI). The outcome was overall survival at 100 days following transplantation. In each model, transplants performed within lower resourced environments were associated with inferior overall survival. In the model with the HDI as the main effect, transplants performed in the lowest HDI quartile (n = 697) were associated with increased hazard for mortality (hazard ratio, 2.42; 95% confidence interval, 1.64 to 3.57; P < .001) in comparison with transplants performed in the countries with the highest HDI quartile. This translated into an 11% survival difference at 100 days (77% for lowest HDI quartile versus 88% for all other quartiles). Country-level macroeconomic indices were associated with lower survival at 100 days after alloHCT for ALL. The reasons for this disparity require further investigation.

  • Impact of Pretransplantation Renal Dysfunction on Outcomes after Allogeneic Hematopoietic Cell Transplantation
  • 2021
  • Ingår i: Transplantation and Cellular Therapy. - : ELSEVIER SCIENCE INC. - 2666-6375 .- 2666-6367. ; 27:5, s. 410-422
  • Tidskriftsartikel (refereegranskat)abstract
    • Renal dysfunction is a recognized risk factor for mortality after allogeneic hematopoietic cell transplantation (alloHCT), yet our understanding of the effect of different levels of renal dysfunction at time of transplantation on outcomes remains limited. This study explores the impact of different degrees of renal dysfunction on HCT outcomes and examines whether the utilization of incremental degrees of renal dysfunction based on estimated glomerular filtration rate (eGFR) improve the predictability of the hematopoietic cell transplantation comorbidity index (HCT-CI). The study population included 2 cohorts: cohort 1, comprising patients age >= 40 years who under went alloHCT for treatment of hematologic malignancies between 2008 and 2016 (n = 13,505; cohort selected given a very low incidence of renal dysfunction in individuals age <40 years), and cohort 2, comprising patients on dialysis at the time of HCT (n = 46). eGFR was measured using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) method. The patients in cohort 1 were assigned into 4 categories-eGFR >= 90 mL/min (n = 7062), eGFR 60 to 89 mL/min (n = 5264), eGFR 45 to 59 mL/min (n = 897), and eGFR <45 mL/min (n=282)-to assess the impact of degree of renal dysfunction on transplantation outcomes. Transplantation outcomes in patients on dialysis at the time of alloHCT were analyzed separately. eGFR <60 mL/min was associated with an increased risk for nonrelapse mortality (NRM) and requirement for dialysis post-HCT. Compared with the eGFR >= 90 group, the hazard ratio (HR) for NRM was 1.46 (P = .0001) for the eGFR 45 to 59 mL/min group and 1.74 (P = .004) for the eGFR <45 mL/min group. Compared with the eGFR >= 90 mL/min group, the eGFR 45 to 59 mL/min group (HR, 2.45; P < .0001) and the eGFR <45 mL/min group (HR, 3.09; P < .0001) had a higher risk of renal failure necessitating dialysis after alloHCT. In addition, eGFR <45 mL/min was associated with an increased overall mortality (HR, 1.63; P < .0001). An eGFR-based revised HCT-CI was also developed and shown to be predictive of overall survival (OS) and NRM, with predictive performance similar to the original HCT-CI. Among 46 patients on dialysis at alloHCT, the 1-year probability of OS was 20%, and that of NRM was 67%. The degree of pretransplantation renal dysfunction is an independent predictor of OS, NRM, and probability of needing dialysis after alloHCT. An eGFR-based HCT-CI is a validated index for predicting outcomes in adults with hematologic malignancies undergoing alloHCT. The outcomes of alloHCT recipients on dialysis are dismal; therefore, one should strongly weigh the significant risks of being on hemodialysis as a factor in determining alloHCT candidacy.
