RESUMEN

BACKGROUND: Several commercial and academic autologous chimeric antigen receptor T-cell (CAR-T) products targeting CD19 have been approved in Europe for relapsed/refractory B-cell acute lymphoblastic leukemia, high-grade B-cell lymphoma and mantle cell lymphoma. Products for other diseases such as multiple myeloma and follicular lymphoma are likely to be approved by the European Medicines Agency in the near future. DESIGN: The European Society for Blood and Marrow Transplantation (EBMT)-Joint Accreditation Committee of ISCT and EBMT (JACIE) and the European Haematology Association collaborated to draft best practice recommendations based on the current literature to support health care professionals in delivering consistent, high-quality care in this rapidly moving field. RESULTS: Thirty-six CAR-T experts (medical, nursing, pharmacy/laboratory) assembled to draft recommendations to cover all aspects of CAR-T patient care and supply chain management, from patient selection to long-term follow-up, post-authorisation safety surveillance and regulatory issues. CONCLUSIONS: We provide practical, clinically relevant recommendations on the use of these high-cost, logistically complex therapies for haematologists/oncologists, nurses and other stakeholders including pharmacists and health sector administrators involved in the delivery of CAR-T in the clinic.

RESUMEN

Acute Graft versus Host Disease (aGvHD) grades 2-4 occurs in 15-60% of pediatric patients undergoing allogeneic haematopoietic stem-cell transplantation (allo-HSCT). The collateral damage to normal tissue by conditioning regimens administered prior to allo-HSCT serve as an initial trigger for aGvHD. DNA-repair mechanisms may play an important role in mitigating this initial damage, and so the variants in corresponding DNA-repair protein-coding genes via affecting their quantity and/or function. We explored 51 variants within 17 DNA-repair genes for their association with aGvHD grades 2-4 in 60 pediatric patients. The cumulative incidence of aGvHD 2-4 was 12% (n = 7) in the exploratory cohort. MGMT rs10764881 (G>A) and EXO rs9350 (c.2270C>T) variants were associated with aGvHD 2-4 [Odds ratios = 14.8 (0 events out of 40 in rs10764881 GG group) and 11.5 (95% CI: 2.3-191.8), respectively, multiple testing corrected p ≤ 0.001]. Upon evaluation in an extended cohort (n = 182) with an incidence of aGvHD 2-4 of 22% (n = 40), only MGMT rs10764881 (G>A) remained significant (adjusted HR = 2.05 [95% CI: 1.06-3.94]; p = 0.03) in the presence of other clinical risk factors. Higher MGMT expression was seen in GG carriers for rs10764881 and was associated with higher IC50 of Busulfan in lymphoblastoid cells. MGMT rs10764881 carrier status could predict aGvHD occurrence in pediatric patients undergoing allo-HSCT.

RESUMEN

STUDY QUESTION: What are the characteristics of patients with conceptions transplanted in childhood and adolescence? SUMMARY ANSWER: Insemination and conception after hematopoietic stem cell transplantation (HCT) in childhood or adolescence was possible, even after myeloablative conditioning regimes, although some patients required reproductive medicine support. WHAT IS KNOWN ALREADY: Preparative regimens of HCT are highly gonadotoxic, which leads to gonadal failure and pubertal development disorders. There are few population-based studies assessing the risk of future infertility in children after HCT. STUDY DESIGN, SIZE, DURATION: We conducted a retrospective study to investigate natural or assisted conceptions and their outcomes in patients <18 years old before their first transplantation who received HCT between 1995 and 2016 and were in the European Society for Blood and Marrow Transplantation (EBMT) registry. Adoptions were excluded from the analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS: Detailed information concerning pregnancy occurrences and outcomes were obtained by a separate questionnaire. Quantitative variables were presented as medians with their interquartile range (IQR) or range, and categorical variables were presented as frequencies and percentages. MAIN RESULTS AND THE ROLE OF CHANCE: In total, 62 988 pediatric patients received a first HCT in EBMT centers between 1995 and 2016. Pregnancy was reported in 406 patients in the database. The median age at transplantation was 15.7 (range: 0.7-18) years, and the median age at declared conception was 25.0 (range: 16.3-38.8) years. Details concerning the first pregnancy and pregnancy outcome were obtained from 99 patients (24%) from the returned questionnaires. The median age at delivery or pregnancy interruption of the females was 23.0 (IQR: 20.8-27) years, with a median time after transplant of 10.7 (IQR: 6.6-15.4) years. Compared with the mean age of healthy women at their first child's birth (29 years old), the transplanted women delivered 5 years earlier (mean: 24.3 years). In terms of conception modality, 13/25 (52%) females conditioned with total body irradiation (TBI) and 50/52 (96%) of those conditioned without TBI conceived naturally. All seven male patients who had been conditioned with TBI achieved fatherhood but required assisted fertilization or used their cryopreserved sperm. In the females, 63/70 (90%) of all conceptions resulted in a live birth, 49/63 (84.5%) were at term and 43/46 (93%) had normal birthweight. Cesarean delivery was performed in 9/61 (15%) especially in women who had received a myeloablative regimen. LIMITATIONS, REASONS FOR CAUTION: In the EBMT pediatric dataset, the age at last follow-up or death was <17 years for 75% of the patients, therefore a longer follow-up for all patients would be necessary to calculate the cumulative incidence of conception for patients transplanted during childhood and allow all patients to realize their reproductive willingness/potential. WIDER IMPLICATIONS OF THE FINDINGS: Reproductive health surveillance and fertility preservation counseling are important in younger transplanted patients. Our results showed that there is a window of opportunity to conceive naturally or with reproductive medicine support. STUDY FUNDING/COMPETING INTEREST(S): Funding was provided by the 'Stiftung für krebskranke Kinder Regio Basiliensis', Basel, Switzerland. All authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER: N/A.

RESUMEN

Osteonecrosis (ON) is an acquired debilitating skeletal disorder, which is caused by a multitude of traumatic and non-traumatic etiological factors. Vascular damage, mechanical stress and increased intraosseous pressure have been discussed as contributors to ON. The optimal treatment of ON remains to be determined, since the current gold standard, core decompression, is insufficiently effective. Specific properties of mesenchymal stromal cells (MSCs) provide the rationale for their assessment in advanced stages of ON: Osteoinductive potential has been demonstrated and MSC preparations of suitable quality for use as medicinal products have been developed. Here we review the scant information on the use of allogeneic or autologous MSCs in advanced ON as well as potentially supportive data from pre-clinical studies with autologous bone marrow mononuclear cells (auto BM-MNCs), which have been studied quite extensively and the presumed therapeutic effect of which was attributed to the rare MSCs contained in these cell products. Outcomes in clinical trials with MSCs and auto-BM-MNCs remain preliminary and non-definitive, at best promising, with respect to their pharmacological effect. Clearly, though, the application of any of these cell therapies was technically feasible and safe in that it was associated with low complication rates. The heterogeneity of cell type and source, study protocols, cell manufacturing, cell properties, cell doses and surgical techniques might contribute to inconsistent results.

RESUMEN

Sinusoidal obstruction syndrome (SOS) is a severe complication of hematopoietic stem cell transplantation (HSCT) that can be fatal, often attributed to the conditioning regimen prior to HSCT. We evaluated the association of SOS risk with gene variants in cystathionase (CTH), an enzyme involved in glutathione synthesis, in 76 children receiving intravenous busulfan (Bu) before HSCT. Our results indicated an association with CTHc.1364 G>T (ORTT=10.6, 95% confidence interval (CI)=2.16, 51.54) and SOS risk, which was sex dependent (female patients, ORTT=21.82, 95% CI=3.590-132.649). The interaction between CTHc.1364 G>T and another risk variant (GSTA1*B) was explored. A recessive model with the use of GSTA1*B*B and CTH c.1364 TT genotypes proved to be useful at predicting SOS occurrence, indicating the possibility of using these gene variants as markers of SOS occurrence and to further individualize preemptive treatment aimed at reducing SOS incidence.

RESUMEN

We determined the indication, outcome, and risk factors of single and multiple hematopoietic stem cell transplantation(s) (HSCT) in children and adolescents mostly with advanced disease. Forty-one out of 483 patients (8.5 %; median age 9 years) diagnosed at the University of Leipzig with hematological and oncological diseases required HSCT from 1999 to 2011. Patients had overall survival (OS) of 63 ± 10 and 63 ± 16 %, event-free survival (EFS) of 57 ± 10 and 42 ± 16 %, relapse incidence (RI) of 39 ± 10 and 44 ± 18 % and nonrelapse mortality (NRM) of 4 ± 4 and 13 ± 9 % at 10 years after one or more allogeneic and autologous HSCT, respectively. One patient in CR1 and five with advanced disease received two HSCT. Four of the six patients maintained/achieved CR for a median of 13 months. Three died of progression and one of NRM. Two patients had a third HSCT and one survived in CR +231 days after HSCT. Risk factors for OS and EFS were disease stage at HSCT and EBMT risk score. Center (pediatric or JACIE accredited pediatric/adult) was not a determinant for survival. Pediatric single and multiple HSCT are important curative approaches for high-risk malignant diseases with low NRM. Efforts to reduce high RI remain the major aim.

RESUMEN

Ataxia telangiectasia (A-T) is a highly pleiotropic disorder. Patients suffer from progressive neurodegeneration, severe bronchial complications, immunodeficiency, hypersensitivity to radiotherapy and elevated risk of malignancies. Leukemia and lymphoma, along with lung failure, are the main causes of morbidity and mortality in A-T patients. At present, no effective therapy for A-T exists. One promising therapeutic approach is bone marrow transplantation (BMT) that is already used as a curative therapy for other genomic instability syndromes. We used an established clinically relevant non-myeloablative host-conditioning regimen and transplanted green fluorescent protein (GFP)-expressing ataxia telangiectasia mutated (ATM)-competent bone marrow-derived cells (BMDCs) into Atm-deficient mice. GFP expression allowed tracking of the potential migration of the cells into the tissues of recipient animals. Donor BMDCs migrated into the bone marrow, blood, thymus, spleen and lung tissue of Atm-deficient mice showing an ATM-competent phenotype. BMT inhibited thymic lymphomas, normalized T-lymphocyte populations, improved weight gain and rearing activity of Atm-deficient mice. In contrast, no GFP(+) cells were found in the cerebellum or cerebrum, and we detected decreased size index in MRI imaging of the cerebellum in 8-month-old transplanted Atm-deficient mice in comparison to wild-type mice. The repopulation with ATM-competent BMDCs is associated with a prolonged lifespan and significantly improved the phenotype of Atm-deficient mice.

RESUMEN

BACKGROUND: The safety and clinical efficacy of adoptive transfer of prospectively isolated antigen-specific T cells are well established. Several competing selection methods are available, one of which is based on immunomagnetic enrichment of T cells secreting IFNγ after incubation with the relevant antigen. The proprietary, GMP-conforming selection technology, called 'cytokine capture system' (CCS) is established in many laboratories for the CliniMACS Plus system. It is robust and efficient, but labour-intensive and incompatible with a single-shift working schedule. An automatic immunomagnetic cell processing system, CliniMACS Prodigy ('Prodigy'), including a protocol for fully automatic CCS execution was recently released. MATERIAL AND METHODS: Feasibility of clinical-scale CMV-specific T-cell selection using Prodigy was evaluated using leukoapheresis products from five healthy CMV sero-positive volunteers. Clinical reagents and consumables were used throughout. RESULTS: The process required no operator input beyond set-up and QC-sample collection, that is, feasibility was given. An IFNγ-secreting target T-cell population was detectable after stimulation, and >2 log-scale relative depletion of not CMV-reactive T cells in the target population was achieved. Purity, that is the frequency of CMV-reactive T cells among all CD3(+) cells ranged between 64 and 93%. CONCLUSION: The CCS protocol on Prodigy is unrestrictedly functional. It runs fully automatically beyond set-up and thus markedly reduces labour. The quality of the products generated is similar to products generated with CliniMACS Plus. The automatic system is thus suitable for routine clinical application.

RESUMEN

Allogeneic hematopoietic stem cell transplantation (HSCT) is currently the only curative therapy for the severe hematopoietic complications associated with Fanconi anemia (FA). In Germany, it is estimated that 10-15 transplants are performed annually for FA. However, because FA is a DNA repair disorder, standard conditioning regimens confer a high risk of excessive regimen-related toxicities and mortality, and reduced intensity regimens are linked with graft failure in some FA patients. Moreover, development of graft-versus-host disease is a major contributing factor for secondary solid tumors. The relative rarity of the disorder limits HSCT experience at any single center. Consensus meetings were convened to develop a national approach for HSCT in FA. This manuscript outlines current experience and knowledge about HSCT in FA and, based on this analysis, general recommendations reached at these meetings.

RESUMEN

BACKGROUND: Allogeneic haematopoietic stem cell transplantation (allo-SCT) may provide donor cytotoxic T cell-/NK cell-mediated disease control in patients with rhabdomyosarcoma (RMS). However, little is known about the prevalence of graft-vs-RMS effects and only a few case experiences have been reported. METHODS: We evaluated allo-SCT outcomes of 30 European Group for Blood and Marrow Transplantation (EBMT)-registered patients with advanced RMS regarding toxicity, progression-free survival (PFS) and overall survival (OS) after allo-SCT. Twenty patients were conditioned with reduced intensity and ten with high-dose chemotherapy. Twenty-three patients were transplanted with HLA-matched and seven with HLA-mismatched grafts. Three patients additionally received donor lymphocyte infusions (DLIs). Median follow-up was 9 months. RESULTS: Three-year OS was 20% (s.e.±8%) with a median survival time of 12 months. Cumulative risk of progression was 67% (s.e.±10%) and 11% (s.e.±6%) for death of complications. Thirteen patients developed acute graft-vs-host disease (GvHD) and five developed chronic GvHD. Eighteen patients died of disease and four of complications. Eight patients survived in complete remission (CR) (median: 44 months). No patients with residual disease before allo-SCT were converted to CR. CONCLUSION: The use of allo-SCT in patients with advanced RMS is currently experimental. In a subset of patients, it may constitute a valuable approach for consolidating CR, but this needs to be validated in prospective trials.

RESUMEN

Stem cell transplantation in pediatric patients with leukemia has been a matter of debate since the first successful transplantation in a child with aplastic anemia in Germany in 1975. Since then, there has been a long way to implement fully stem cell transplantation strategies into the treatment studies organized within BFM Groups for first line or second line treatment of acute and chronic leukemias and myelodysplastic syndrome. The role of different risk groups, different donors, stem cell sources and alternative approaches as haploidentical transplantation as well have been studied as the impact of chimerism and minimal residual disease. Finally, for all leukemias and myelodysplastic syndromes integrated treatment pathways have been developed, which integrate stem cell transplantation on an evidence base into the treatment of the patient.

RESUMEN

Background: Asthma rehabilitation at high altitude is common. Little is known about the acute and subacute cardiopulmonary acclimatization to high altitude in middle-aged asthmatics without other comorbidities. Methods: In this prospective study in lowlander subjects with mostly mild asthma who revealed an asthma control questionnaire score >0.75 and participated in a three-week rehabilitation program, we assessed systolic pulmonary artery pressure (sPAP), cardiac function, and extravascular lung water (EVLW) at 760 m (baseline) by Doppler-echocardiography and on the second (acute) and last day (subacute) at a high altitude clinic in Kyrgyzstan (3100 m). Results: The study included 22 patients (eight male) with a mean age of 44.3 ± 12.4 years, body mass index of 25.8 ± 4.7 kg/m2, a forced expiratory volume in 1 s of 92% ± 19% predicted (post-bronchodilator), and partially uncontrolled asthma. sPAP increased from 21.8 mmHg by mean difference by 7.5 [95% confidence interval 3.9 to 10.5] mmHg (p < 0.001) during acute exposure and by 4.8 [1.0 to 8.6] mmHg (p = 0.014) during subacute exposure. The right-ventricular-to-pulmonary-artery coupling expressed by TAPSE/sPAP decreased from 1.1 by -0.2 [-0.3 to -0.1] mm/mmHg (p < 0.001) during acute exposure and by -0.2 [-0.3 to -0.1] mm/mmHg (p = 0.002) during subacute exposure, accordingly. EVLW significantly increased from baseline (1.3 ± 1.8) to acute hypoxia (5.5 ± 3.5, p < 0.001) but showed no difference after 3 weeks (2.0 ± 1.8). Conclusion: In otherwise healthy asthmatics, acute exposure to hypoxia at high altitude increases pulmonary artery pressure (PAP) and EVLW. During subacute exposure, PAP remains increased, but EVLW returns to baseline values, suggesting compensatory mechanisms that contribute to EVLW homeostasis during acclimatization.

RESUMEN

Autologous stem cell transplantation (SCT) has become standard therapy in high risk stage IV neuroblastoma (NB) patients. Residual NB cells in the bone marrow (BM) shortly before SCT may shape the overall survival.Thus, we sought to thoroughly investigate minimal residual disease (MRD) in BM prior to SCT using conventional and real time RT-PCR for tyrosine hydroxylase (TH) as well as morphology. To avoid influence of residual NB cells in the stem cell harvest, 17 patients transplanted with MRD negative grafts (n=11 CD34-selected and n=6 unmanipulated) are included in the final analysis, only.35% of these patients are alive with a median follow up of 8.6 years. In the BM of 9/17 patients residual NB cells could be detected < 40 d before SCT. These patients had a significant lower overall survival compared to patients without BM involvement based on combined RT-PCR and morphology results (11% vs. 62%, p=0.026) or using RT-PCR, only (p=0.01). In contrast morphology on its own did not lead to a significant discrimination between both groups.Our results obtained in a small cohort of stage IV NB patients suggest that MRD diagnostic in the BM shortly before SCT might be a valuable predictive tool for these patients but requires conformation in a multicenter study.

RESUMEN

BACKGROUND: Risk stratification criteria for patients with Ewing's sarcoma family of tumors (ESFT) are still limited. We hypothesized divergent human leukocyte antigen (HLA) patterns in ESFT patients and compared HLA-A, -B and -DR phenotype frequencies of patients with advanced ESFT with those of healthy controls. PATIENTS: HLA types of all German Caucasian patients with advanced ESFT and available HLA-A, -B and -DR data registered in the European Group for Blood and Marrow Transplantation, Paediatric Registry for Stem Cell Transplantation and the MetaEICESS data bases (study group, n=30) were retrospectively compared with HLA types of healthy German stem cell donors (control group, n=8 862 for single HLA frequencies and n=8 839 for allele combinations). Study group patients had been immuno-typed due to eligibility for allogeneic stem cell transplantation for high risk of treatment failure, and thus constituted a selected subgroup of ESFT patients. RESULTS: After Bonferroni correction for multiple testing (PC), phenotype frequencies of HLA-A24 remained significantly higher in the study group compared to controls (PC<0.05). Furthermore, several HLA combinations were significantly more frequent in the study group compared to controls (all PC<0.05). CONCLUSION: We report an increased incidence of circumscribed HLA patterns in German Caucasians with advanced ESFT. The possible clinical significance of this observation has to be re-assessed in prospective trials comprising larger ESFT patient numbers of all risk groups.

RESUMEN

The peripheral blood stem cell transplantation (PBSCT) represents a specific, but stressful therapy for hemato-oncological diseases. While for adults, data suggest positive eff ects for a supportive sport therapy, this question is not evaluated sufficiently for children. The objective of this study was to examine the integration of sports activity into pediatric PBSCT and to indicate attainable results. This 2-step case-control-study included 23 children and adolescents from the PBSCT: During the isolation phase 13 patients trained 3 times per week on a cycle ergometer and passed a course with different sports equipment. Apart from recording physiologic adaptations, quality of live was inquired in a pre-post design using questionnaires. Guided interviews according to necessity and requirements for sports activity at the PBSCT unit completed the evaluation and were used for the intervention as well as for the control group (n = 10) without sports therapy. On the ergometer, patients trained average 25 min with 0.6 watt / kg. In the majority, a loss of muscular power could be avoided. Quality of life and fatigue symptoms improved by trend. Interview analysis showed general acceptance of physical activity during PBSCT. After initial skepticism due to the additional burden, our implementation study showed the feasibility of supportive sports therapy in PBSCT. Quality and flexibility of the equipment should be higher than normal and different physical and psychological conditions of the patients should be anticipated and integrated into the training program.

RESUMEN

Patients with advanced Ewing sarcoma (AES) carry a poor prognosis. Retrospectively, we analyzed 66 AES patients treated with allogeneic stem cell transplantation (allo-SCT) receiving HLA-mismatched (group A, n = 39) versus HLA-matched grafts (group B, n = 27). Median age at diagnosis was 13 years, and 15 years (range 3-49 years) at allo-SCT. The two groups did not differ statistically in distribution of gender, age, remission status/number of relapses at allo-SCT, or risk stratum. 9/39 (23%) group A versus 2/27 (7%) group B patients developed severe acute graft versus host disease (GvHD). Of patients alive at day 100, 7/34 (21%) group A versus 9/19 (47%) group B patients had developed chronic GvHD. In group A, 33/39 (85%) versus 20/27 (74%) group B patients died of disease and 1/39 (3%) versus 1/27 (4%) patients died of complications, respectively. Altogether 12/66 (18%) patients survived in CR. Median EFS 24 months after allo-SCT was 20% in both groups, median OS was 27% (group A) versus 17% (group B), respectively. There was no difference in EFS and OS in AES patients transplanted with HLA-mismatched versus HLA-matched graft in univariate and multivariate analyses. In this analysis, CR at allo-SCT is a condition for survival (p < 0.02).

RESUMEN

The 22q13.3 deletion syndrome results from loss of terminal segments of varying sizes at 22qter. Few genotype-phenotype correlations have been found but all patients have mental retardation and severe delay, or absence of, expressive speech. We carried out clinical and molecular characterization of 13 patients. Developmental delay and speech abnormalities were common to all and comparable in frequency and severity to previously reported cases. Array-based comparative genomic hybridization showed the deletions to vary from 95 kb to 8.5 Mb. We also carried out high-resolution 244K array comparative genomic hybridization in 10 of 13 patients, that defined the proximal and distal breakpoints of each deletion and helped determine the size, extent, and gene content within the deletion. Two patients had a smaller 95 kb terminal deletion with breakpoints within the SHANK3 gene while three other patients had a similar 5.5 Mb deletion implying the recurrent nature of these deletions. The two largest deletions were found in patients with ring chromosome 22. No correlation could be made with deletion size and phenotype although complete/partial SHANK3 was deleted in all patients. There are very few reports on array comparative genomic hybridization analysis on patients with the 22q13.3 deletion syndrome, and we aim to accurately characterize these patients both clinically and at the molecular level, to pave the way for further genotype-phenotype correlations.

RESUMEN

OBJECTIVE: Treatment options in patients with persistent or locally recurrent cervical cancer are limited. The aim of this study was to determine the chance of cure and associated morbidity following pelvic exenteration. PATIENTS AND METHODS: Consecutive patients who underwent pelvic exenteration between January 1992 and December 2006 at the University Hospital of Bern or the Karlsruhe Medical Center were evaluated. Time to recurrence, type of exenteration and urinary diversion, pathological stage, postoperative complications and survival were assessed. RESULTS: Initial therapy prior to diagnosis of persistent or locally recurrent disease included radiation therapy in 51%. Anterior exenteration was performed in 37 (86%) and total exenteration in 6 (14%). Half of the women underwent additional procedures. A continent urinary diversion was constructed in 16 and an ileal conduit in 27 patients. Early postoperative complications were generally minor and only 2 patients required surgical intervention. Four intestinal fistulas were successfully treated conservatively. Late complications were mainly tumor-related. Complication rates associated with the urinary diversion were low and there was no difference in complications between continent and incontinent diversions. The overall disease-specific 5-year survival rate after exenteration was 36.5%. Survival correlated significantly with surgical margin status. CONCLUSION: In patients with persistent or locally recurrent gynecological malignancy of the pelvis, exenteration is a viable option with long-term survival in over one third of patients. Continent urinary diversion did not show higher complication rates than an ileal conduit and should be considered even in irradiated patients. This may be of greater significance in younger patients in whom an intact body image can play an important role in quality of life.
