- Between 1982 and 2009 a total of 92 patients with myelofibrosis (MF) in chronic phase underwent allo-SCT in nine Nordic transplant centers. Myeloablative conditioning (MAC) was given to 40 patients, and reduced intensity conditioning (RIC) was used in 52 patients. The mean age in the two groups at transplantation was 46±12 and 55±8 years, respectively (P<0.001). When adjustment for age differences was made, the survival of the patients treated with RIC was significantly better (P=0.003). Among the RIC patients, the survival was significantly (P=0.003) better for the patients with age <60 years (a 10-year survival close to 80%) than for the older patients. The type of stem cell donor did not significantly affect the survival. No significant difference was found in TRM at 100 days between the MAC- and the RIC-treated patients. The probability of survival at 5 years was 49% for the MAC-treated patients and 59% in the RIC group (P=0.125). Patients treated with RIC experienced significantly less aGVHD compared with patients treated with MAC (P<0.001). The OS at 5 years was 70, 59 and 41% for patients with Lille score 0, 1 and 2, respectively (P=0.038, when age adjustment was made). Twenty-one percent of the patients in the RIC group were given donor lymphocyte infusion because of incomplete donor chimerism, compared with none of the MAC-treated patients (P<0.002). Nine percent of the patients needed a second transplant because of graft failure, progressive disease or transformation to AML, with no significant difference between the groups. Our conclusions are (1) allo-SCT performed with RIC gives a better survival compared with MAC. (2) age over 60 years is strongly related to a worse outcome and (3) patients with higher Lille score had a shorter survival.

- Background: An allogeneic antitumour effect has been reported for various cancers. We evaluated the experience of allogeneic haematopoietic stem cell transplantation (HSCT) for renal cell carcinoma (RCC) in 124 patients from 21 European centres. Patients and methods: Reduced intensity conditioning and peripheral blood stem cells from an HLA-identical sibling (n = 106), a mismatched related (n = 5), or an unrelated (n = 13) donor were used. Immunosuppression was cyclosporine alone, or combined with methotrexate or mycophenolate mofetil. Donor lymphocyte infusions (DLI) were given to 42 patients. The median follow-up was 15 (range 3-41) months. Results: All but three patients engrafted. The cumulative incidence of moderate to severe, grades II-IV acute GVHD was 40% and for chronic GVHD it was 33%. Transplant-related mortality was 16% at one year. Complete (n = 4) or partial (n = 24) responses, median 150 (range 42-600) days post-transplant, were associated with time from diagnosis to HSCT, mismatched donor and acute GVHD II-IV. Factors associated with survival included chronic GVHD (hazards ratio, HR 4.12, P < 0.001), DLI (HR 3.39, P < 0.001), < 3 metastatic sites (HR 2.61, P = 0.002) and a Karnofsky score > 70 (HR 2.33, P = 0.03). Patients (n = 17) with chronic GVHD and given DLI had a 2-year survival of 70%. Conclusion: Patients with metastatic RCC, less than three metastatic locations and a Karnofsky score > 70% can be considered for HSCT. Posttransplant DLI and limited chronic GVHD improved the patient survival.

- This study aimed to determine the impact of tyrosine-kinase inhibitors given pre- and post-allogeneic stem cell transplantation on long term outcome of patients allografted for Philadelphia chromosome-positive acute lymphoblastic leukemia. This retrospective analysis from the Acute Leukemia Working Party of EBMT included 473 de novo Philadelphia chromosome-positive acute lymphoblastic leukemia patients in first complete remission who underwent an allogeneic stem cell transplantation using an human leucocyte antigen-identical sibling or human leucocyte antigen-matched unrelated donor between 2000 and 2010. Three hundred ninety patients received tyrosine-kinase inhibitors before transplant, 329 at induction and 274 at consolidation. The Kaplan-Meier estimates of leukemia-free survival, overall survival, cumulative incidences of relapse incidence, and non-relapse mortality at 5 years were 38%, 46%, 36% and 26%, respectively. In multivariate analysis, tyrosine-kinase inhibitors given before allogeneic stem cell transplantation was associated with a better overall survival (HR=0.68; P=.04) and was associated with lower relapse incidence (HR=0.5; P=.01). In the post-transplant period, multivariate analysis identified prophylactic tyrosine-kinase inhibitors administration to be a significant factor for improved leukemia-free survival (HR=0.44; P=.002) and overall survival (HR=0.42; P=.004), and a lower relapse incidence (HR=0.40; P=.01). In conclusion, over the past decade, tyrosine-kinase inhibitors administration before allogeneic stem cell transplantation has significantly improved the long term allogeneic stem cell transplantation outcome of adult Philadelphia chromosome-positive acute lymphoblastic leukemia. Prospective studies will be of great interest to further confirm the potential benefit of the prophylactic use of tyrosine-kinase inhibitors in the post-transplant setting.

Tidskriftsartikel (refereegranskat)abstract
- Background: Autologous haematopoietic stem cell transplantation (HSCT) is a viable option for treatment of aggressive multiple sclerosis (MS). No randomised controlled trial has been performed, and thus, experiences from systematic and sustained follow-up of treated patients constitute important information about safety and efficacy. In this observational study, we describe the characteristics and outcome of the Swedish patients treated with HSCT for MS.Methods: Neurologists from the major hospitals in Sweden filled out a follow-up form with prospectively collected data. Fifty-two patients were identified in total; 48 were included in the study and evaluated for safety and side effects; 41 patients had at least 1 year of follow-up and were further analysed for clinical and radiological outcome. In this cohort, 34 patients (83%) had relapsing-remitting MS, and mean follow-up time was 47 months.Results: At 5 years, relapse-free survival was 87%; MRI event-free survival 85%; expanded disability status scale (EDSS) score progression-free survival 77%; and disease-free survival (no relapses, no new MRI lesions and no EDSS progression) 68%. Presence of gadolinium-enhancing lesions prior to HSCT was associated with a favourable outcome (disease-free survival 79% vs 46%, p=0.028). There was no mortality. The most common long-term side effects were herpes zoster reactivation (15%) and thyroid disease (8.4%).Conclusions: HSCT is a very effective treatment of inflammatory active MS and can be performed with a high degree of safety at experienced centres.

- We studied GVHD after donor lymphocyte infusion (DLI) in 328 patients with relapsed CML between 1991 and 2004. A total of 122 patients (38%) developed some form of GVHD. We analyzed GVHD by clinical presentation (acute or chronic GVHD) and onset time after the first DLI (early (<= 45 days) or late (>45 days)). There was a significant overlap between onset time and clinical presentation. Some form of GVHD occurred at a median of 104 days, acute GVHD at 45 days and chronic GVHD at 181 days after DLI. The clinical presentation was acute GVHD in 71 patients, of whom 31 subsequently developed chronic GVHD subsequently. De novo chronic GVHD was seen in 51 patients. OS for all patients was 69% (95% confidence interval (CI) 63-75) at 5 years, DLI-related mortality was 11% (95% CI 8-15) and disease-related mortality was 20% (95% CI 16-25). Risk factors for developing GVHD after DLI were T-cell dose at first DLI, the time interval from transplant to DLI and donor type. In time-dependent multivariate analysis, GVHD after DLI was associated with a risk of death of 2.3-fold compared with patients without GVHD. Clinical presentation as acute GVHD and early onset GVHD were associated with increased mortality.

- To specify incidence and risk factors for secondary autoimmune diseases (AD) after HSCT for a primary AD, we retrospectively analysed AD patients treated by HSCT reported to EBMT from 1995 to 2009 with at least one secondary AD (cases) and those without (controls). After autologous HSCT, 29 amongst 347 patients developed at least one secondary AD within 21.9 (0.6-49) months and after allogeneic HSCT, 3 amongst 16 patients. The observed secondary AD included: autoimmune hemolytic anemia (n=3), acquired haemophilia (n=3), autoimmune thrombocytopenia (n=3), antiphospholipid syndrome (n=2), thyroiditis (n=12), blocking TSHR-ab (n=1), Graves' disease (n=2), myasthenia gravis (n=1), rheumatoid arthritis (n=2), sarcoidosis (n=2), vasculitis (n=1), psoriasis (n=1) and psoriatic arthritis (n=1). After autologous HSCT for primary AD, the cumulative incidence of secondary AD was 9.8+/-2 % at 5 years, lupus erythematosus as primary AD and antithymocyte-globulin use plus CD34+ graft selection were important risk factors for secondary AD by multivariate analysis. With a median follow-up of 6.2 (0.54-11) years after autologous HSCT, 26/29 patients with secondary AD were alive, 2 died during their secondary AD (antiphospholipid syndrome, haemophilia) and 1 death was HSCT related. This European multicenter study underlines the need for careful management and follow-up for secondary AD after HSCT.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Effective T-cell depletion is a prerequisite for haploidentical peripheral blood progenitor cell (PBPC) transplantation. This study was performed to investigate the performance of magnetic cell sorting–based direct large-scale T-cell depletion, which is an attractive alternative to standard PBPC enrichment procedures. STUDY DESIGN AND METHODS: PBPCs were harvested from 11 human leukocyte antigen (HLA)-haploidentical donors. T cells labeled with anti-CD3–coated beads were depleted with a commercially available magnetic separation unit (CliniMACS, Miltenyi Biotec) with either the Depletion 2.1 (D2.1, n = 11) or the novel Depletion 3.1 (D3.1, n = 12) program. If indicated, additional CD34+ selections were performed (n = 6). Eleven patients received T-cell-depleted grafts after reduced-intensity conditioning. RESULTS: The median log T-cell depletion was better with the D2.1 compared to the D3.1 (log 3.6 vs. log 2.3, p < 0.05) and was further improved by introducing an immunoglobulin G (IgG)-blocking step (log 4.5 and log 3.4, respectively). The D3.1 was superior to the D2.1 (p < 0.05) in median recovery of CD34+ cells (90% vs. 78%) and in median recovery of CD3– cells (87% vs. 76%). The median processing times per 1010 total cells were 0.90 hours (D2.1) and 0.35 hours (D3.1). The transplanted grafts (directly T-cell–depleted products with or without positively selected CD34+ cells) contained a median of 10.5 × 106 per kg CD34+, 0.93 × 105 per kg CD3+, and 11.6 × 106 per kg CD56+. Rapid engraftment was achieved in 10 patients. The incidences of acute graft-versus-host disease were less than 10 percent (Grade I/II) and 0 percent (Grade III/IV). CONCLUSION: The novel D3.1 program with IgG blocking enables highly effective, time-saving large-scale T-cell depletion. Combining direct depletion techniques with standard CD34+ selection enables the composition of grafts optimized to the specific requirements of the patients.

Long-term survival of patients with CLL after allogeneic transplantation : A report from the European Society for Blood and Marrow Transplantation
- 2017

Tidskriftsartikel (refereegranskat)abstract
- Even with the availability of targeted drugs, allogeneic hematopoietic cell transplantation (allo-HCT) is the only therapy with curative potential for patients with CLL. Cure can be assessed by comparing long-term survival of patients to the matched general population. Using data from 2589 patients who received allo-HCT between 2000 and 2010, we used landmark analyses and methods from relative survival analysis to calculate excess mortality compared with an age-, sex- and calendar year-matched general population. Estimated event-free survival, overall survival and non-relapse mortality (NRM) 10 years after allo-HCT were 28% (95% confidence interval (CI), 25-31), 35% (95% CI, 32-38) and 40% (95% CI, 37-42), respectively. Patients who passed the 5-year landmark event-free survival (N=394) had a 79% probability (95% CI, 73-85) of surviving the subsequent 5 years without an event. Relapse and NRM contributed equally to treatment failure. Five-year mortality for 45- and 65-year-old reference patients who were event-free at the 5-year landmark was 8% and 47% compared with 3% and 14% in the matched general population, respectively. The prospect of long-term disease-free survival remains an argument to consider allo-HCT for young patients with high-risk CLL, and programs to understand and prevent late causes of failure for long-term survivors are warranted, especially for older patients.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Approximately 570 patients are diagnosed with multiple myeloma (MM) in Sweden each year. Few studies have estimated the cost of treatment for these patients. OBJECTIVE: The purpose of this study was to retrospectively investigate the direct hospital resource utilization and costs associated with the treatment of patients with MM in southwest Sweden. METHODS: Patients aged > or =18 years who initiated first-line chemotherapy in the year 2001 at hospitals in southwestern Sweden were included in this retrospective chart review. Direct hospital-based resources and their corresponding costs (year-2006 euros) for each patient were calculated until the patient's death, or until December 31, 2005. Costs for outpatient and terminal stage care related to MM were not included. RESULTS: Ninety-four patients were included; 20 were still alive at study completion. Mean age at diagnosis was 76 years and patients were followed for a mean of 32.7 months; 55% were males and 74% had at least 1 comorbidity. First-, second-, and third-line treatment lasted a mean of 24.3, 5.8, and 2.6 months, and included 2.8, 2.6, and 3.1 chemotherapy drugs per patient, respectively. Of the 80 patients who received first-line chemotherapy, 72 were prescribed melphalan and 55 patients received a combination of melphalan and prednisone, as recommended by Swedish treatment guidelines. The mean total cost per patient was euro88,199, or euro2770 per patient-month. Therapy-induced and comorbidity-related events constituted 42% of total costs, as much as autologous stem-cell transplantation and inpatient care together. Chemotherapy, bisphosphonate, and blood cell-enhancement drugs each amounted to only 2% of total costs, but chemotherapy drugs increased from euro29/month in first-line therapy to euro453/month in third-line therapy. CONCLUSIONS: The cost of treating Swedish patients with MM varied greatly between individuals but, overall, chemotherapy drugs constituted only a minor part of the total monthly cost (2%), whereas costs for inpatient stays and therapy-induced adverse events or comorbidity-related events accounted for 35% and42%, respectively. There was no significant differencein monthly cost between treatment lines.

Tidskriftsartikel (refereegranskat)abstract
- Until recently, only retrospective studies had been published on salvage high-dose melphalan (HDM) with autologous stem cell 'transplantation' (ASCT). In a prospective, nonrandomized phase-2 study, we treated 53 bortezomib-naïve patients with bortezomib-dexamethasone as induction and bortezomib included in the conditioning regimen along with the HDM. Median progression-free survival (PFS), time to next treatment (TNT) and overall survival (OS) after start of reinduction therapy were 21.6, 22.8 and 46.6 months, respectively. For 49 patients who completed salvage bortezomib-HDM(II) with ASCT, there was no significant difference of PFS and TNT after HDM (II) compared with after the initial HDM(I), and thus patients were their own controls (PFS (I: 20.1 vs II: 19.3 months (P=0.8)) or TNT (I: 24.4 vs II: 20.7 months (P=0.8)). No significant differences in the response rates after salvage ASCT compared with the initial ASCT. Bortezomib-HDM conditioning combo was feasible, and toxicity was as expected for patients treated with bortezomib and ASCT. In conclusion, in bortezomib-naïve patients treated at first relapse with salvage ASCT including bortezomib, PSF and TNT did not differ significantly from initial ASCT and median OS was almost 5.5 years with acceptable toxicity. A recent prospective randomized study confirms salvage ASCT to be an effective treatment.Bone Marrow Transplantation advance online publication, 29 June 2015; doi:10.1038/bmt.2015.125.

Implementing safe and robust Total Marrow Irradiation using Helical Tomotherapy – A practical guide
- 2019
-
Ingår i: Physica Medica. - : Elsevier BV. - 1120-1797. ; 60, s. 162-167
-
Tidskriftsartikel (refereegranskat)abstract
- Total Marrow Irradiation (TMI) with Helical Tomotherapy is a radiotherapy treatment technique that targets bone marrow and sanctuary sites prior to stem cell or bone marrow transplantation (SCT/BMT). TMI is a complex procedure that involves several critical steps that all need to be carefully addressed for a successful implementation, such as dose homogeneity in field junctions, choice of target margins, integrity of treatment and back-up planning. In this work we present our solution for a robust and reproducible workflow throughout the treatment chain and data for twenty-three patients treated to date. Material & Methods: Patients were immobilized in a whole body vacuum cushion and thermoplastic mask. CT-scanning and treatment were performed in two parts with field matching at the upper thigh. Target consisted of marrow containing bone and sanctuary sites. Lungs, kidneys, bowel, heart and liver were defined as organs at risk (OAR). A fast surface scanning system was used to position parts of the body not covered by the imaging system (MVCT) as well as to reduce treatment time. Results: All patients completed their treatment and could proceed with SCT/BMT. Doses to OARs were significantly reduced and target dose homogeneity was improved compared to TBI. Robustness tests performed on field matching and patient positioning support that the field junction technique is adequate. Replacing MVCT with optical surface scanning reduced the treatment time by 25 min per fraction. Conclusion: The methodology presented here has shown to provide a safe, robust and reproducible treatment for Total Marrow Irradiation using Tomotherapy.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Total body irradiation (TBI) is commonly used prior to hematopoietic stem cell transplantation (HSCT) in myeloablative conditioning regimens. However, TBI may be replaced by total marrow irradiation (TMI) at centres with access to Helical TomoTherapy, a modality that has the advantage of delivering intensity-modulated radiotherapy to long targets such as the entire bone marrow compartment. Toxicity after organ sparing TMI prior to HSCT has not previously been reported compared to TBI or with regard to engraftment data. Methods: We conducted a prospective observational study on 37 patients that received organ sparing TMI prior to HSCT and compared this cohort to retrospective data on 33 patients that received TBI prior to HSCT. Results: The 1-year graft-versus-host disease-free, relapse-free survival (GRFS) was 67.5% for all patients treated with TMI and 80.5% for patients with matched unrelated donor and treated with TMI, which was a significant difference from historical data on TBI patients with a hazard ratio of 0.45 (P =.03) and 0.24 (P <.01). Engraftment with a platelet count over 20 [K/µL] and 50 [K/µL] was significantly shorter for the TMI group, and neutrophil recovery was satisfactory in both treatment cohorts. There was generally a low occurrence of other treatment-related toxicities. Conclusions: Despite small cohorts, some significant differences were found; TMI as part of the myeloablative conditioning yields a high 1-year GRFS, fast and robust engraftment, and low occurrence of acute toxicity.

- Background: An unexplained survival difference was observed in the Nordic Myeloma Study Group (NMSG) high-dose therapy trial 5/94 in Denmark compared with Sweden and Norway; however, this difference was eliminated in the subsequent NMSG trial 7/98. It was hypothesized that a detailed analysis of potential explanations would reveal important information for future designs of clinical trials for multiple myeloma (MM) patients in Denmark. Patients and Methods: The analysis is based on 3 consecutive clinical trials coordinated by NMSG from 1990 to 2000: NMSG 4/90 including 583 patients, NMSG 5/94 including 274 patients and NMSG 7/98 including 414 patients with newly diagnosed MM. Event-free and total survival rates were calculated according to the Kaplan-Meier method, and survival comparisons were made by the log-rank test. The Cox proportional hazards regression model was used to estimate the prognostic importance of selected variables. Results: The analysis revealed no differences in disease stages, prognostic variables, or inclusion bias at diagnosis between the 3 consecutive NMSG trials. However, the number of initial treatment failures was low, and post-relapse survival was superior in Swedish patients as compared to Danish patients. These differences were explained by a defensive clinical practice in Denmark during 1994-1997 for patients with poor risk refractory or relapsed disease. Conclusion: These initially observed differences were subsequently eliminated most likely as a consequence of international collaboration improving diagnosis, research infrastructure, clinical training, and education as planned within the European Myeloma Network (EMN).

Tidskriftsartikel (refereegranskat)abstract
- Background and aim: The clinical impact of multiparametric flow cytometry (MFC) in multiple myeloma (MM) is still unclear and under evaluation. Further progress relies on multiparametric profiling of the neoplastic plasma cell (PC) compartment to provide an accurate image of the stage of differentiation. The primary aim of this study was to perform global analysis of CD expression on the PC compartment and subsequently to evaluate the prognostic impact. Secondary aims were to study the diagnostic and predictive impact. Design and methods: The design included a retrospective analysis of MFC data generated from diagnostic bone marrow (BM) samples of 109 Nordic patients included in clinical trials within NMSG. Whole marrow were analyzed by MFC for identification of end-stage CD45(-)/CD38(++) neoplastic PC and registered the relative numbers of events and mean fluorescence intensity (MFI) staining for CD19, CD20, CD27, CD28, CD38, CD44, CD45, CD56, and isotypes for cluster analysis. Results: The median MFC-PC number was 15%, and the median light microscopy (LM)-PC number was 35%. However, the numbers were significant correlated and the prognostic value with an increased relative risk (95% Cl) of 3.1 (1.7-5.5) and 2.9 (1.4-6.2), P < 0.0003 and P < 0.004 of MFC-PC and LM-PC counts, respectively. Unsupervised clustering based on global MFI assessment on PC revealed two clusters based on CD expression profiling. Cluster I with high intensity for CD56, CD38, CD45, right-angle light-scatter signal (SSC), forward-angle light-scatter signal (FSC), and low for CD28, CD19, and a Cluster II, with low intensity of CD56, CD38, CD45, SSC, FSC, and high for CD28, CD19 with a median survival of 39 months and 19 months, respectively (P = 0.02). Conclusions: The MFC analysis of MM BM samples produces diagnostic, prognostic, and predictive information useful in clinical practice, which will be prospectively validated within the European Myeloma Network (EMN).

- Twenty-three patients with advanced and heavily pretreated myeloma were treated with thalidomide. Starting dose was 200 mg/d, and 20 patients had dose escalations up to 400 (n = 5), 600 (n = 12) or 800 mg/d (n = 3), usually in divided doses. Nineteen patients were refractory to recent chemotherapy, and four had untreated relapse after prior intensive therapy. Ten out of 23 patients (43%) achieved partial response (PR, nine with refractory and one with relapsed disease), six patients had minor response or stabilization of the disease and four had disease progression. Another three patients died early from advanced myeloma at less than 3 weeks of thalidomide therapy. Of the 10 patients with PR, seven had a better response than after any prior therapy, despite vincristine-doxorubicin-dexamethasone (VAD)-based treatment in all but one and high-dose melphalan with autologous stem cell support in four. Time to achieve PR was rapid in patients receiving thalidomide in divided doses (median 31 d). Responses also included reduced bone marrow plasma cell infiltration and improved general status. Normalized polyclonal gammaglobulin levels were seen in four cases. Six out of 10 patients with PR remained in remission with a median time on treatment of 23 weeks (range 15- 50 weeks). Sedation was common but usually tolerable, and some patients continued full- or part-time work. Four patients had skin problems, three patients had pneumonia, one hypothyrosis, one sinus bradycardia and one minor sensory neuropathy. Thalidomide may induce good partial remissions in advanced refractory myeloma with tolerable toxicity, and should be evaluated in other settings for myeloma patients. Divided thalidomide doses seem to reduce time to achieve remission and may improve response rate.

- BACKGROUND: There is a lack of knowledge about sibling stem cell donors' experiences pre-donation and the waiting period before the donation might have been long. The donors and their corresponding sibling recipients were simultaneously included in two different interview studies. The results from the recipient study have been presented in a separate paper. PURPOSE: The aim was to explore the experiences of being a stem cell donor for a sibling, prior to donation. METHOD: Ten adult sibling donors were interviewed prior to stem cell donation. The interviews were digitally recorded, transcribed verbatim and subjected to qualitative content analysis. RESULTS: The main theme Being a cog in a big wheel describes the complex process of being a sibling donor prior to donation, covering a mixture of emotions and thoughts. The four subthemes Being available, Being anxious, Being concerned and Being obliged cover the various experiences. The sibling donors' experiences are influenced by the quality of the relationship with the sick sibling. CONCLUSIONS: Sibling stem cell donors go through a complex process once they have accidentally got involved in. They have been asked to become a donor; it was not a voluntary choice. In caring for sibling stem cell donors the nurses should be aware of the complexity of the process they experience and take into consideration their personal situation and needs. Providing optimal care for both sibling donors and their corresponding recipients is a challenge, and further improvement and exploration are needed.

- Factors associated with changes in quality of life in patients undergoing allogeneic haematopoietic stem cell transplantation It is well known that patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) experience changes in quality of life. We investigated factors associated with quality of life changes in adult HSCT patients. The Functional Assessment of Cancer Therapy - Bone Marrow Transplantation (FACT-BMT) scale, supplemented with the Functional Assessment of Chronic Illness Therapy - Spiritual Well-being (FACIT-Sp) subscale, was administered on three occasions, immediately before transplantation, 100 days and 12 months after transplantation. Analyses of nine selected factors were made where changes in quality of life were found. Seventy-five patients were included and 40 of these completed the study. Emotional well-being was found to improve between the baseline and 100 days, while all other dimensions deteriorated, including overall quality of life. Physical and social/family well-being deteriorated between the baseline and the 12-month follow-up, while emotional well-being improved. The main factors associated with deteriorating quality of life over time were found to be significant infections, female gender and transplantation with stem cells from a sibling donor. In our further studies we aim to focus on the relationships between patients and sibling donors in order to improve the care. Careful attention must be paid to continuous adequate information during the transplantation procedure.

- Background Allogeneic haematopoietic stem cell transplantation (HSCT) offers a potential cure for a variety of diseases but is also associated with significant risks. With HSCT the donor is either a relative, most often a sibling, or an unrelated registry donor. Purpose The aim was to explore patients’ experiences, immediately before transplantation, regarding having a sibling as donor. Method Ten adult patients with sibling donors were interviewed before admission for HSCT. The interviews were digitally recorded, transcribed verbatim and subjected to qualitative content analysis. Results The main theme Being in no man’s land is a metaphor for the patients’ complex situation with its mixture of emotions and thoughts prior to transplantation. The three subthemes Trust in the sibling donor, Concern about others and Loss of control cover the various experiences. The patient’s experiences are influenced by their personal situation and the quality of the relationship with the sibling donor. While patients feel secure in having a sibling donor, they are dependent for their survival on the cell donation and feel responsible for the donor’s safety during donation. These emotions intensify the patients’ sense of dependency and loss of control. Conclusions In caring for HSCT patients the nurses should be aware of the complexity of the patients’ situation and keep in mind that having a sibling donor might imply extra pressure, including a sense of responsibility. Caring for both patients and sibling donors optimally is a challenge, which needs further improvement and exploration.

- The first international recommendations and guidelines for the care of sibling stem cell donors were established in 2010, and have not yet been evaluated. However, a model for information and care of adult potential sibling stem cell donors (the IC model) developed and introduced at the Skåne University Hospital, Lund, Sweden, in 2005 conforms closely to them. The IC model aims to protect the privacy of potential donors, support and respect their free choice, and identify quickly those unwilling or unable to donate and thus minimize delay in seeking alternative donors. To evaluate the IC model a questionnaire survey in 2010 gathered the perceptions and views on information provision; influences over decision making; and care provision under the IC model of 148 adult siblings informed about SCT donation, and asked to undergo HLA-typing since September 2005 at the hospital. The results suggest the IC model works well but highlights areas for improvement, such as in delivery of HLA typing results to non-matched siblings, and a need to further prevent complicating influence from health professionals and relatives on the decision to undergo HLA typing. Thus improved, the IC model could provide the groundwork for other SCT units seeking to implement the recommendations and guidelines.

- Background: The first international recommendations and guidelines for the care of sibling stem cell donors were established in 2010 and have not yet been evaluated. However, a model for information and care of adult potential sibling stem cell donors (the IC model) developed and introduced at Skåne University Hospital, Lund, Sweden, in 2005 conforms closely to them. The IC model aims to protect the privacy of potential donors, support and respect their free choice, and identify quickly those unwilling or unable to donate and thus minimize delay in seeking alternative donors. All contacts with potential sibling donors are handled by the SCT (Stem Cell Transplantation) team. If the sibling is unwilling or unable to donate, HLA (Human Leukocyte Antigen) typing is not performed and the patient is told only that there is no possible donor among the siblings. To protect the sibling donor’s privacy, the physician and nurse assigned to the donor are never those responsible for the patient.Objectives: The main aim of the present study was to evaluate the IC model by surveying adult potential sibling stem cell donors’ perceptions and views regarding the provision of information, staff and relatives’ influence over decision making, and the care provision by health professionals around the time of the decision whether to undergo HLA typing.Methods: A questionnaire survey containing 30 questions was performed in 2010 gathering the perceptions and views on information provision; influences over decision making; and care provision under the IC model of 148 adult siblings informed about SCT donation and asked to undergo HLA typing since September 2005 at the hospital. The questionnaire responses were analysed using descriptive statistical methods.Results: The results suggest the IC model works well but highlights areas for improvement, such as in delivery of HLA typing results to non-matched siblings and a need to further prevent complicating influence from health professionals and relatives on the decision to undergo HLA typing.Conclusion: The majority of the siblings was satisfied with the information and care provided, and found the aspects of information, care provision and support important. The IC model could provide the groundwork for other SCT units seeking to implement handling of potential adult sibling stem cell donors according to the international recommendations and guidelines published after the IC model was developed and introduced.

- The aim of the study was to assess the role of allogeneic stem cell transplantation (SCT) in patients diagnosed with BCR-ABL1-positive acute myeloid leukemia (AML). Fifty-seven patients (median age, 48 years, range: 19-67) with BCR-ABL1 positive AML undergoing SCT were identified. The majority of the patients (70%) received a TKI before the transplant. At SCT 48 patients were in CR (45 in CR1), while 9 patients were transplanted in a more advanced stage of the disease. MRD was negative (BCR-ABL1/ABL<104) at time of SCT in 36.1% (14/40). After SCT, 16 (61.5%) out of 26 patients with MRD positive at transplantation reached MRD negativity. After a median follow-up of 6.3 years (0.7-14.2), NRM, RI, LFS, OS, and GRFS at 5 years were 18.1%, 37%, 44.2%, 53.8%, and 32.1%, respectively. The cumulative incidence of acute GvHD grade II-IV was 16.4%, incidence of chronic GvHD 24.9%, and of extensive cGvHD 21.4%, respectively. In patients who received SCT in CR1, 5-yr NRM, RI, LFS, OS, and GRFS were 15.9%, 36.4%, 46.5%, 59.4%, and 34.9%, respectively. Univariate analysis showed that age (<50 vs. ≥50 years) was associated with RI (5-yr: 22.7 vs. 50%), LFS (5-yr: 61.9 vs. 31.8%), and GRFS (5-yr: 52.4 vs. 18.2%), whereas MRD-negative status before SCT was associated with an improved GRFS (38.9 vs. 16.7%). We conclude that the outcome of patients <50 years of age with BCR-ABL1-positive AML receiving allogeneic SCT in CR is relatively favorable, possibly reflecting the beneficial effect of the use of TKI.
