This follow-up study of a randomized, prospective trial included 192 patients with newly diagnosed severe aplastic anemia receiving antithymoglobulin and cyclosporine, with or without granulocyte ...colony-stimulating factor (G-CSF). We aimed to evaluate the long-term effect of G-CSF on overall survival, event-free survival, probability of secondary myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML), clinical paroxysmal nocturnal hemoglobinuria, relapse, avascular osteonecrosis and chronic kidney disease. The median follow-up was 11.7 years (95% CI, 10.9-12.5). The overall survival rate at 15 years was 57±12% in the group given G-CSF and 63±12% in the group not given G-CSF (
=0.92); the corresponding event-free survival rates were 24±10% and 23±10%, respectively (
=0.36). In total, 9 patients developed MDS or AML, 10 only a clonal cytogenetic abnormality, 7 a solid cancer, 18 clinical paroxysmal nocturnal hemoglobinuria, 8 osteonecrosis, and 12 chronic kidney disease, without any difference between patients treated with or without G-CSF. The cumulative incidence of MDS, AML or isolated cytogenetic abnormality at 15 years was 8.5±3% for the G-CSF group and 8.2±3% for the non-G-CSF group (
=0.90). The cumulative incidence of any late event including myelodysplastic syndrome or acute myeloid leukemia, isolated cytogenetic abnormalities, solid cancer, clinical paroxysmal nocturnal hemoglobinuria, aseptic osteonecrosis, chronic kidney disease and relapse was 50±12% for the G-CSF group and 49±12% for the non-G-CSF group (
=0.65). Our results demonstrate that it is unlikely that G-CSF has an impact on the outcome of severe aplastic anemia; nevertheless, very late events are common and eventually affect the prognosis of these patients, irrespectively of their age at the time of immunosuppressive therapy (NCT01163942).
Infections are frequently experienced complications for patients undergoing haematopoietic cell transplant (HCT). To assess current infection prevention strategies, an international survey among HCT ...nurses was conducted by the Nurses Group and IDWP of the EBMT. Nurse representatives from all EBMT transplant centres were invited to complete an online questionnaire on protective environment in adult and paediatric HCT units. A total of 141 complete questionnaires were returned for the isolation section and 26 for the paediatric section, the majority of respondents (89.4%) being nurses. A small number of centres (7.1%) reported not allowing visitors, the rest have rules for entering patient rooms. Most HCT units (99.3%) indicated that nurses play a critical role in infection prevention and measures differed between bacterial infections and viral infections. Many of the paediatric units (57.7%) had a play area, applying rules of entry. To our knowledge, this is the first survey on protective environment directed at nurses within HCT centres. Despite having different practices, most HCT units tend to decrease isolation procedures and the use of PPE for multi-drug resistant organisms. This must concur with an increase of hand hygiene compliance, for which our data show that there is still room for improvement.
Hepatitis-associated aplastic anemia (HAAA) has been reported in 23% to 33% of patients who received orthotopic liver transplantation (LT) for acute liver disease of unknown origin (nonviral ...hepatitis). In this situation, hematopoietic stem cell transplantation (HSCT) might be a curative option. Here the authors report on 6 patients who received HSCT after LT for nonviral HAAA hepatitis. The outcomes were interpreted in the context of recently reported immune suppressive therapy (IST) outcomes in 8 patients with HAAA and to HSCT outcomes in patients with HAAA who recovered from hepatitis without undergoing LT. All patients transplanted by using HLA-identical sibling donors (3 of 6) were alive and had normal liver function and hematopoiesis without graft versus host disease. Both patients receiving bone marrow from a matched unrelated donor (MUD) experienced extensive graft versus host disease that was fatal for one patient. Thereby, the authors conclude that HSCT can be considered as a first-choice treatment for this category of patients when HLA-identical donors are available. When no HLA-identical donor is available, IST should be applied as HSCT with other donor sources might be reserved for IST nonresponders or poor responders.
The aim of this retrospective study was to investigate the safety and efficacy of allogeneic hematopoietic cell transplantation (alloHCT) in patients pre-treated with ibrutinib. Eligible were ...patients aged >18 years allotransplanted for chronic lymphocytic leukemia (CLL) or mantle cell lymphoma (MCL) after prior exposure to ibrutinib who were registered with the EBMT registry. Seventy patients (CLL 48, MCL 22) were included. At the time of alloHCT, 73% of the patients were ibrutinib responsive. All patients except one engrafted, and acute GVHD grade 2-4 (3-4) was observed in 49% (12%) of 68 evaluable patients. The cumulative incidence of chronic GVHD was 54% 1 year after transplant. In the CLL group, 12-month non-relapse mortality, relapse incidence (RI), progression-free survival (PFS), and overall survival (OS) were 10, 30, 60, and 72%, respectively, and in the MCL group 5, 19, 76, and 86%, respectively. Pre-transplant ibrutinib failure and poor performance status predicted inferior RI, PFS and OS in the CLL group. In conclusion, ibrutinib does not affect the safety of a subsequent alloHCT. While the relatively high post-transplant relapse risk in ibrutinib-exposed patients with CLL deserves further study, in patients with MCL consolidating disease responses to ibrutinib with alloHCT seems to be a promising option.
Sexual dysfunction after allogeneic hematopoietic cell transplantation (allo-HCT) is a common long-term complication. We conducted a European multicenter cross-sectional study of adult allo-HCT ...recipients who had survived >2 years and their partners to investigate sexual functioning after HCT and to evaluate whether discussion about sexual functioning between the transplant team and the survivor and partner was perceived to have taken place. In total, 136 survivors (77 males, 59 females) and 81 partners (34 males, 47 females) participated. Median age was 56 and 54 years in male and female survivors, respectively. Forty-seven percent of male and 65% of female survivors and 57% of male and 59% of female partners reported clinically relevant sexual problems. Sixty-two percent of survivors and 79% of partners reported that sexual functioning had not been discussed with them during transplant. Standardized sexual functioning scores were correlated with self-reported health status in survivors (rho = 0.24, p = 0.009). The high prevalence of sexual dysfunction warrants additional studies focusing on the impact of changes in sexuality for patients as well as their partners. Future studies should also investigate which methods that are effective in preventing or treating sexual problems after allo-HCT.
Eltrombopag (ELT), an oral thrombopoietin receptor agonist, has recently emerged as a promising new drug for the treatment of aplastic anemia (AA). How ELT is used outside of clinical trials in the ...real-world setting and results of this treatment are not known. We conducted therefore a retrospective survey on the use of ELT in AA among EBMT member centers. We analyzed the 134 patients reported in our survey together with 46 patients recently published by Lengline et al. The median follow-up from start of ELT treatment was 15.3 months, with 85.6% patients alive at last follow-up. Importantly, only 28.9% of our patients received ELT according to the FDA/EMA label as monotherapy in the relapsed/refractory setting, whereas 16.7% received ELT upfront. The overall response rate in our cohort was 62%, very similar to the results of the pivotal ELT trial. In multivariate analysis, combination therapy with ELT/cyclosporine/ATG and response to previous therapy were associated with response. Overall survival was favorable with a 1-year survival from ELT start of 87.4%. We identified age, AA severity before ELT start and response to ELT as variables significantly associated with OS. Two patients transformed to MDS; other adverse events were mostly benign. In sum, ELT is used widely in Europe to treat AA patients, mostly in the relapsed/refractory setting. Response to ELT is similar to the clinical trial data across different age groups, treatment lines, and treatment combinations and results in favorable survival.
Allogeneic hematopoietic cell transplantation (HCT) is the only curative option for bone marrow failure or hematopoietic malignant diseases for Fanconi anemia (FA) patients. Although results have ...improved over the last decades, reaching more than 90% survival when a human leukocyte antigen (HLA)‐identical donor is available, alternative HCT donors are still less reported. We compared HCT outcomes using HLA‐mismatched unrelated donors (MMUD; n = 123) or haplo‐identical donors (HDs), either using only in vivo T cell depletion (n = 33) or T cells depleted in vivo with some type of graft manipulation ex vivo (n = 59) performed for FA between 2000 and 2018. Overall survival (OS) by 24 months was 62% (53–71%) for MMUD, versus 80% (66–95%) for HDs with only in vivo T cell depletion and 60% (47–73%) for HDs with in vivo and ex vivo T cell depletion (p = .22). Event‐free survival (EFS) was better for HD‐transplanted FA patients with only in vivo T cell depletion 86% (73–99%) than for those transplanted from a MMUD 58% (48–68%) or those with graft manipulation 56% (42–69%) (p = .046). Grade II‐IV acute graft‐versus‐host disease (GVHD) was 41% (MMUD) versus 40% (HDs with no graft manipulation) versus 17% (HDs with T cell depleted graft), (p = .005). No differences were found for the other transplant related outcomes. These data suggest that HDs might be considered as an alternative option for FA patients with better EFS using unmanipulated grafts.
Allogeneic hematopoietic stem cell transplantation (allo‐HSCT) is curative for bone marrow failure in patients with Fanconi anemia (FA), but the presence of a malignant transformation is associated ...with a poor prognosis and the management of these patients is still challenging. We analyzed outcome of 74 FA patients with a diagnosis of myelodysplastic syndrome (n = 35), acute leukemia (n = 35) or with cytogenetic abnormalities (n = 4), who underwent allo‐HSCT from 1999 to 2016 in EBMT network. Type of diagnosis, pre‐HSCT cytoreductive therapies and related toxicities, disease status pre‐HSCT, donor type, and conditioning regimen were considered as main variables potentially influencing outcome. The 5‐year OS and EFS were 42% (30‐53%) and 39% (27‐51%), respectively. Patients transplanted in CR showed better OS compared with those transplanted in presence of an active malignant disease (OS:71%48‐95 vs 37% 24‐50,P = .04), while none of the other variables considered had an impact. Twenty‐two patients received pre‐HSCT cytoreduction and 9/22 showed a grade 3‐4 toxicity, without any lethal event or negative influence on survival after HSCT(OS:toxicity pre‐HSCT 48% 20‐75% vs no‐toxicity 51% 25‐78%,P = .98). The cumulative incidence of day‐100 grade II‐IV a‐GvHD and of 5‐year c‐GvHD were 38% (26‐50%) and 40% (28‐52%). Non‐relapse‐related mortality and incidence of relapse at 5‐years were 40% (29‐52%) and 21% (11‐30%) respectively, without any significant impact of the tested variables. Causes of death were transplant‐related events in most patients (34 out of the 42 deaths, 81%). This analysis confirms the poor outcome of transformed FA patients and identifies the importance of achieving CR pre‐HSCT, suggesting that, in a newly diagnosed transformed FA patient, a cytoreductive approach pre‐HSCT should be considered if a donor have been secured.
