This study aimed to investigate the best nutritional assessment method for leukemia patients after HSCT, and find the possible nutritional risk of the patients during the transplantation process in order to intervene in the patients with nutritional risks and undernourished patients timely, so that the entire transplantation process could be successfully completed. Methods： A prospective study was performed in 108 leukemia patients after HSCT, and different nutritional assessment methods, including nutritional risk screening 2002 （NRS2002）, mini nutritional assessment （MNA）, subjective globe assessment （SGA） and malnutritional universal screening tools （MUST）, were used. The associations between nutritional status of these patients and nutritional assessment methods were analyzed. Results： A total of 108 patients completed SGA, and 99 patients completed NRS2002, MNA and MUST. During the treatment process, 85.2% of the patients lost weight, wherein, 50% lost weight greater than 5%, and 42.6% had significantly reduced food intake. For nutritional risk assessment, the positive rates of NRS2002, MNA and MUST were 100%, 74.7% and 63.6%, respectively. There was a significant difference （P〈0.05） among the positive rates of NRS2002, MNA and MUST. In undernutrition assessment, the positive rate of SGA （83.3%） was significantly higher than that of MNA （17.2%） （P〈0.05）, and the incidence rate of nutritional risk among leukemia patients _〈30 years old was greater than that of patients 〉30 years old （P〈0.05）. Conclusions： Patients with leukemia were in poor nutritional status during and after HSCT. The leukemia patients 〈30 years old had a greater incidence rate of nutritional risk. As nutritional risk screening tool, the specificity of NRS2002 is not high, but it can be used for evaluating nutritional deficiencies. MNA is a good nutritional risk screening tool, but not an adequate tool for nutritional assessment. If assessment of undernutrition is necessary, the combination of all these screening tools and clinical laboratory indicators should he applied to improve accuracy.展开更多

Methods： We relxospectively analyzed the data from 41 patients with chemotherapy-sensitive LL who underwent hematopoietic stem cell transplantation （HSCT） from December 1989 to December 2009 in a single institution. Results： HSCT was conducted as first-line consolidation therapy and salvage therapy in 36 and 5 patients, respectively. The median follow-up was 97.1 months （range, 24.6-173.1 months）. The 5-year overall survival （OS） and event-free survival （EFS） rate were 64% and 47% for the initially treated patients, respectively, and were both 20% for the relapsed ones. Bone marrow （BM） involvement and chemotherapy cycles prior to transplantation were identified as significant prognostic factors for EFS in multivariate analysis. Conclusions These results confirm that AHSCT is a reasonable option for chemotherapy-sensitive LL patients in first complete remission （CR1）.展开更多

Methods： The clinical and follow-up data of 93 AL patients （median age, 30 years） undergoing allogeneic HSCT in Xiangya Hospital over the past 12 years were collected, and the potential factors affecting the efficacy and prognosis of allogeneic HSCT patients were determined. Results： Hematopoietic reconstitution was achieved in 90 patients. At the last follow-up, the incidences of severe acute graft versus host disease （aGvHD） and extensive chronic GvHD （cGvHD） were 14.0% and 20.0%, the 3-year cumulative incidence of transplantation related mortality （TRM） and relapse rate were 16.8%±6.1% and 21.3%±6.7%, and the estimated 3-year overall survival （OS） and disease-free survival （DFS） of the patients were 64.6%±5.4% and 56.5%±5.5%, respectively. Univariate analysis indicated that age older than 40 years, HLA mismatch, and severe lung infection within the first 100 days after transplantation were risk factors for severe aGvHD, age older than 40 years, HLA mismatch, severe lung infection within the first 100 days after transplantation, and severe aGvHD were risk factors for TRM, high-risk AL and lack of cGvHD were risk factors for relapse （all P〈0.05）. Survival estimation showed that HLA mismatch, severe lung infection occurring within the first 100 days post-transplantation, high-risk AL severe aGvHD and lack of cGvHD were risk factors associated with poor prognosis （all P〈0.05）. Further multivariate analyses revealed that severe lung infection within the first 100 days post-transplantation, severe aGvHD and lack of cGvHD were independent risk factors for unfavorable outcomes （all P〈0.05）. Conclusions： Allogeneic HSCT can improve the DFS of AL patients, and severe lung infection within the first 100 days post-transplantation, severe aGvHD and lack of cGvHD are independent risk factors affecting the prognosis.展开更多

Current strategies for management that usually include salvage chemotherapy, donor lymphocytic infusion and second transplantation. Our study assessed the efficacy of decitabine（DAC） for treating patients with acute lymphoblastic leukemia（ALL） who relapsed after allogeneic hematopoietic stem cell transplantation（allo-HSCT）. We retrospectively analyzed the outcomes of 12 patients with relapsed ALL after allo-HSCT who received DAC therapy. Nine patients received DAC combined with chemotherapy and donor stem cell infusion, and 3 patients received single-agent DAC. Ten of the 12 patients achieved complete remission（CR）, 1 achieved a partial remission（PR）, and 1 had no response（NR） after treatment at the latest follow-up（LFU）, the median survival was 11.2 months（range, 3.8–34, 7 months）. The 1-and 2-year overall survival（OS） rates were 50%（6/12） and 25%（3/12）, respectively. Five patients were still alive; 4 had maintained CR and 1 was alive with disease. Patients with Philadelphia chromosome-positive ALL had higher survival rate than patients with Philadelphia chromosome-negative ALL（57.1% vs. 20%）. No aggravated flares of graft-versus-host disease（GVHD） were observed during DAC treatment. Therefore, DAC may be a promising therapeutic agent for ALL recurrence after allo-HSCT.展开更多

Lung transplantation （LTX） has been rarely reported as a treatment option for selected HSCT recipients with this problem. In the present study, we reported six patients who underwent LTX due to BOS after HSCT （two females, four males） from January 2012 to December 2014 in our center. The median time from HSCT to diagnosis of BOS was 2.5 years （ranging from 1 to 5 years）. At a median time of 4 years （ranging from 2 to 5 years） after diagnosis of BOS, four patients received bilateral sequential LTX, and two patients received single LTX. One of the recipients suffered from mild acute rejection after LTX, another suffered from primary lung graft dysfunction on post-operation day 2, and three experienced fungal infections. The median time for follow-up after LTX was 19.5 months （ranging from 12 to 39 months）. At present, all patients are alive with good functional capacity and no relapse of BOS and hematologic malignancy conditions. Patients who received bilateral LTX have better pulmonary functions than patients who received single LTX.展开更多
