During the past 40 years substantial progress has been made in the treatment of hematologic malignancies, particularly in some subgroups of patients. Today, cure is attainable for patients with Hodgkin's disease and a considerable proportion of patients with high-grade non-Hodgkin's lymphoma. Prognosis is improving in patients with acute promyelocytic leukemia and, to some extent, those with acute lymphoblastic and myeloid leukemias. However, the majority of patients who suffer from a hematologic malignancy live with incurable disease. In CLL, outside the setting of a clinical trial, it is advisable to postpone treatment until the manifestation of clinical symptoms. It is yet to be determined whether treatment strategies based on new prognostic parameters such as cytogenetics can change the course of disease. In indolent lymphomas, cure is not attainable for the vast majority of patients; the median survival of 9 to 10 years has remained unchanged for several decades. Nevertheless, there has been a dramatic change in therapeutic paradigms in the past few years. For the first time, with the use of new cytostatic drugs and recombinant monoclonal antibodies, it is possible to achieve molecular remissions. Whether this will translate into cure or prolonged survival is still to be determined. In Hodgkin's disease, which is curable when treated with radiotherapy, chemotherapy, or combined therapy, depending on the stage of disease, the focus of future studies must be on prevention of early relapse and on primary resistant disease, both of which present a very poor prognosis. Finally, regardless of underlying malignancy and prognosis, the preservation of quality of life is of major consideration in the setting of hematologic malignancies.

This study was aimed to explore the effect and feasibility of reduced conditioning intensity allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of relapsed ETO positive acute myeloid leukemia (AML) patients. Fifteen cases of relapsed AML received the reducing conditioning intensity allo-HSCT from January 2011 to January 2013 in Beijing Military Command General Hospital. All patients were high-risk type of relapsed or refractory AML, including 10 males and 5 females, aged from 16 to 48 years old with mean age of 32.5 years. Ten cases are HLA-identical matching and other 5 cases are HLA-haploidentical.donors received granulocyte colony-stimulating factor (G-CSF) to mobilize the peripheral blood stem cell for transplantation. Conditioning regimen was fludarabine combined with busulfex, cytarabine and cyclophosphamide. The preventive donor's peripheral blood stem cell infusion were performed after 3 months of transplantation, and the toxicity, GVHD and disease-free survival were observed in patients after transplantation. The results showed that all patients achieved hematopoietic reconstitution, the average time of neutrophils ≥ 0.5 × 10⁹/L and platelets ≥ 20 × 10⁹/L were 15.5 d and 16.8 d respectively. Implantation was confirmed by the evidence of 100% donor hematopoiesis. Follow-up to June 2014, with a median follow-up duration of 27.5 months (18-54 months), GVHD occurred in 8 cases of all patients, one died of complication, the other 4 cases died of relapse and the other three patients remained in disease-free survival. The disease-free survival rate of 2-year was 66.7%,the longest disease-free survival time was up to 54 months. It is concluded that the reduced conditioning intensity allo-HSCT is the effective and safe method for relapsed AML with ETO-positive, and it may be chosen as a treatment method for relapsed ETO positive AML patients.

This 12th biannual report of the Cochrane Haematological Malignancies Group highlights recently published randomized controlled trials in the field of hemato-oncology, covering the publication period from September 1, 2009, through June 30, 2010. Implication for clinical practice and methodological aspects are the main principles used to select trials for this report. Studies on tyrosine kinase inhibitors for patients with chronic myeloid leukemia were identified through electronic search of MEDLINE with a broad search filter that covered all topics in hemato-oncology combined with a highly sensitive search filter for randomized studies as described in the Cochrane Handbook for Systematic Reviews of Interventions.

We report a case of pure red cell aplasia (PRCA) subsequent to an allogeneic bone marrow transplantation with a major ABO mismatch, which was resistant to the standard treatment options such as plasma exchange, erythropoietin and changes in the immunosuppressive treatment. Accordingly, two cycles of Rituximab therapy were administered without success. The patient had a chronic graft-vs.-host disease of the liver, which meant that an additional donor leukocyte infusion could not be introduced. Instead, purified CD34(+) cells were administered after fludarabine and antithymocyte globulin therapy. As a result, the PRCA was resolved and the antidonor isohemagglutinin titer became undetectable.

Current regular blood transfusion programs and chelation treatment have considerably improved survival of patients with thalassemia, which resulted in a larger proportion of adult patients. However, disease- and treatment-related complications in these patients progress over time, causing severe morbidity and shortened life expectancy. Stem cell transplantation still remains the only cure currently available for patients with thalassemia. This study updates transplant outcomes in 107 adult patients with median age of 22 years (range, 17-35 years) who received bone marrow transplantation (BMT) from human leukocyte antigen (HLA)-identical related donors between 1988 and 1996 (group A) and describes the results of BMT in 15 adult patients with median age of 21 years (range, 17-31 years) who were treated with a new treatment protocol (Protocol 26) between 1997 and 2003 (group B). The probability of survival, event-free survival, nonrejection mortality, and rejection for group A patients were 66%, 62%, 37%, and 4%, respectively, with a median follow-up of 12 years (range, 8.3-16.2 years). Group B patients treated with the new protocol had some improvement in thalassemia-free survival (67%) and lower transplant-related mortality (27%) than that of previous protocols. However, transplant-related mortality in these high-risk patients remains elevated. Current myeloablative BMT in adult patients is characterized by higher transplant-related toxicity due to an advanced phase of disease. Although this new approach to transplant adult patients with a reduced-dose intensity-conditioning regimen has improved thalassemia-free survival, transplant-related mortality in these high-risk patients remains elevated.
