Abstract
The probability of achieving long term remission for patients with refractory acute leukaemia is very low. Allogeneic stem cell transplantation (SCT) is offered to these patients in order to improve their dismal outcome. We retrospectively analyzed 361 acute leukaemia patients, who underwent allogeneic SCT in the Hadassah's bone marrow transplantation department between the years 2005 and 2012 and identified 84 patients with active leukaemia at transplantation. Median age was 34 years. Sixty four patients were diagnosed with acute myeloid leukaemia (AML), 18 patients with acute lymphoblastic leukaemia and two with biphenotypic leukaemia. The majority of patients were diagnosed with de-novo AML and transplanted at relapse. In the surviving patients, median follow up was 15 months. One year OS was 20%. At time of last follow up, 13 patients were alive (15.5%): ten patients with AML and two patients with acute lymphoblastic leukaemia. In the univariate analysis, factors associated with significantly better overall survival were as follows: matched unrelated donor (p = 0.006), matched donor (p = 0.014) and occurrence of acute graft-versus-host disease (aGVHD) (p = 0.019). Karnofsky performance score at SCT and occurrence of cGVHD were found to be borderline significant. Only matched unrelated donor and aGVHD were found to affect overall survival significantly in the multivariate analysis. Other than performance score at SCT, none of the pretransplant patients' characteristics were found to influence survival. In conclusion, as none of the pretransplant characteristics were found to influence the ability to select the patients that will benefit from HSC transplantation, this work supports offering HSCT to all active leukaemia eligible patients with reasonable performance status.

Abstract
Hematopoietic stem cell transplantation is a multifactorial process. Some of the predictors exhibit time-dependent effects. We present a systematic analysis and description of selected clinical predictors influencing outcome in a time-dependent manner based on an analysis of registry data from the German Registry for Stem Cell Transplantation. A total of 14,951 patients with acute myeloid leukemia, acute lymphocytic leukemia, myelodysplastic syndrome and non-Hodgkin lymphoma transplanted with peripheral blood stem cells or bone marrow grafts were included. Multivariate Cox regression models were tested for time-dependent effects within each diagnosis group. Predictors not satisfying the proportional hazards assumption were modeled in a time-dependent manner, extending the Cox regression models. Similar patterns occurred in all diagnosis groups. Patients with a poor Karnofsky performance score (<80) had a high risk for early mortality until day 139 following transplantation (HR 2.42, CI: 2.19-2.68; P<0.001) compared to patients with a good Karnofsky performance score (80-100). Afterwards the risk reduced to HR 1.43, CI: 1.25-1.63; P<0.001. A lower mortality risk was found for patients after conditioning treatment with reduced intensity until day 120 post transplant (HR: 0.81 CI: 0.75-0.88; P<0.001). After this, a slightly higher risk could be shown for these patients. Similarly, patients who had received a PBSC graft exhibited a significantly lower mortality risk until day 388 post transplantation (HR 0.79, CI: 0.73-0.85; P<0.001), reversing to a significantly higher risk afterwards (HR 1.23, CI: 1.08-1.40; P=0.002). Integrating time dependency in regression models allows a more accurate description and quantification of clinical predictors to be made, which may help in risk assessment and patient counseling.

PBSC vs BM grafts with myeloablative conditioning for unrelated donor transplantation in adults with high-risk ALL. Bone Marrow Transplant 2014; 49:773-9.

Abstract
Few studies are available that compare PBSC and BM from unrelated donors, especially in adult high-risk ALL. To determine which graft source is superior in adult high-risk ALL, we analyzed the long-term outcomes of 106 consecutive transplants from 8/8-matched or 7/8-matched unrelated donors (38 PBSC vs 68 BM). All patients received a uniform strategy of pre-transplant therapy, myeloablative conditioning and GVHD prophylaxis. At 5 years, PBSC transplants showed higher incidence of chronic GVHD than did BM transplants (74.3% vs 46.7%, P=0.001). PBSC transplants showed outcomes comparable to those of BM transplants for relapse (23.7% vs 28.1%), non-relapse mortality (18.4% vs 25.0%), disease-free survival (57.9% vs 46.9%) and OS (57.9% vs 50.0%). In a separate comparison of outcomes between the two graft sources according to the presence of a Ph chromosome, no significant advantage of PBSC over BM was found in both subgroups of patients. Our data suggest that the outcomes of unrelated donor transplantation are similar between PBSC and BM in adult high-risk ALL. Whether PBSC should be the preferred graft source for a specific subgroup of adult ALL needs to be further investigated.

Abstract
AIMS To compare the efficacy of hematopoietic stem cell transplantation (HSCT) from human leukocyte antigen (HLA)-haploidentical related donors (RD) and unrelated donors (URD) in the treatment of leukemia. METHODS Ninety-three leukemia patients underwent allogeneic HSCT were divided into two groups: 51 cases of RD-HSCT and 42 cases of URD-HSCT. In the RD-HSCT group, a preconditioning regimen with fludarabine (Flu) + busulfan (Bu) + cytosine arabinoside (Ara-C) was used in 42 patients and total body irradiation (TBI) + Flu + Ara-C was used in the remaining 9. RESULTS In the URD-HSCT group, a modified preconditioning regimen with Bu + cyclophosphamide was used in 35 patients, while the other 7 patients underwent treatment with TBI + Flu. After transplantation, the occurrence rate of grade II-IV acute graft-versus-host disease (GVHD) was 46.0 and 51.2% in the two groups. Likewise, the rate of chronic GVHD was 46.0 and 63.4%, respectively. No significant differences in the occurrence of acute and chronic GVHD were detected between the two groups. The differences in early-stage infection rate after transplantation, recurrence rate, 3-year survival rate, and disease-free survival rate between the two groups were not significant. CONCLUSION HLA-haploidentical RD-HSCT with enhanced preconditioning and administration of immunosuppressants showed a clinical efficacy similar to that of URD-HSCT against leukemia, without the risk of increased infection and GVHD.

Abstract
While previous studies have shown comparable clinical results for related and unrelated bone marrow transplantation (BMT), the transplantation outcomes for related and unrelated peripheral blood stem cell transplantation (PBSCT) may not follow the same pattern due to a higher incidence of graft-versus-host disease (GVHD)-related morbidity and mortality in the case of long-term survival after unrelated PBSCT. Thus, given the higher possibility of an impaired quality of life due to severe GVHD in long-term survivors who receive unrelated PBSCT, the selection of the stem cell source needs to be decided very carefully. In addition, strategic approaches, such as the extended use of immunosuppressant as a GVHD prophylaxis, the use of antithymocyte globulins (ATGs), choosing a younger donor, and optimizing the CD34+ cell dose, need to be adopted to improve the transplantation outcomes by minimizing GVHD-related morbidity and mortality in an unrelated PBSCT setting. This review article provides a comparison of BMT and PBSCT, and related and unrelated PBSCT, plus introduces several adoptable strategies to improve the outcomes of unrelated PBSCT.

Abstract
Strategies that exploit natural killer (NK) cell alloreactivity or attenuate rather than deplete T cells have resulted in improved outcomes after haploidentical hematopoietic stem cell transplantation (HSCT). However, no approach has consistently produced the triad of optimal immune reconstitution, avoidance of significant graft-versus-host disease (GVHD), and durable control of malignancy. We developed a two-step approach to haploidentical HSCT in which the lymphoid and myeloid portions of the graft are given in two separate steps in order to control and optimize T-cell dosing. The initial results from these trials have included robust immune reconstitution, low rates of toxicity and significant GVHD, and durable disease control in good-risk patients, as well as insights regarding a threshold for T-cell dosing above which graft-versus-tumor (GVT) effects might be expected. Patients who were not in remission at the time of HSCT had higher rates of relapse requiring efforts to further strengthen GVT effects. Second-generation trials are underway to further exploit changes in the dosing and timing of administration of T cells and to optimize donor selection in an effort to decrease relapse rates in high-risk patients.

Abstract
Recent technological developments in biomedicine have facilitated the generation of data on the anatomical, physiological and molecular level for individual patients and thus introduces opportunity for therapy to be personalized in an unprecedented fashion. Generation of patient-specific stem cells exemplifies the efforts toward this new approach. Cell-based therapy is a highly promising treatment paradigm; however, due to the lack of consistent and unbiased data about the fate of stem cells in vivo, interpretation of therapeutic effects remains challenging hampering the progress in this field. The advent of nanotechnology with a wide palette of inorganic and organic nanostructures has expanded the arsenal of methods for tracking transplanted stem cells. The diversity of nanomaterials has revolutionized personalized nanomedicine and enables individualized tailoring of stem cell labeling materials for the specific needs of each patient. The successful implementation of stem cell tracking will likely be a significant driving force that will contribute to the further development of nanotheranostics. The purpose of this review is to emphasize the role of cell tracking using currently available nanoparticles.
