BACKGROUNDWide application of umbilical cord blood transplantation (UCBT) in adult patients is limited by low cell-dose available in one umbilical cord blood (UCB) unit. The aim of this study was to investigate the safety and long-term outcomes of UCBT from unrelated donors in adult and adolescent patients with leukemia.

METHODSThirteen patients with leukemia received double-unit UCBT with human leukocyte antigen (HLA) mismatched at 0 - 2 loci. We analyzed the engraftment, graft-versus-host disease (GVHD) and survival.

RESULTSTwelve evaluable patients (92.3%) had neutrophil and platelet engraftment at a median of 21 days (range, 16-38 days) and 34 days (range, 25 - 51 days), respectively. At day 30, engraftment was derived from one donor in 8 patients (66.7%, 95%CI 40.0% - 93.4%), and from both donors in 4 patients (33.3%, 95%CI 6.7% - 60.0%) with 1 unit predominated. Unit with larger nucleated cell (NC) dose would predominate in engraftment (P = 0.039), whereas CD34(+) cell dose or HLA-match failed to demonstrate any relationship with unit predominance. Only one patient developed grade II acute graft-versus-host disease (aGVHD). Chronic GVHD (cGVHD) was observed in 2 of 11 patients who survived more than 100 days, and both were limited. The median follow-up after transplantation for the 13 patients was 45 months (range 1.5 - 121.0 months) and 72 months (range 41.0 - 121.0 months) for the 8 alive and with full donor chimerism. The 5-year cumulative disease free survival (DFS) was (61.5 ± 13.5)%. Of the 13 patients, 5 patients died in 1 year and 1-year transplantation related mortality (TRM) was 23.1% (95%CI 0.2% - 46.0%).

CONCLUSIONDouble-unit UCBT from unrelated donors with HLA-mismatched at 0-2 loci may overcome the cell-dose barrier and be feasible for adults and adolescents with leukemia.

The aim of this study was to investigate the incidence, risk factors of acute renal failure (ARF) after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and evaluate its effect on the prognosis of patients after allo-HSCT. A retrospective analysis was performed in 86 patients undergoing allo-HSCT at Peking University First Hospital from June 2003 to April 2007. ARF is defined as a doubling of baseline serum creatinine at any time during the first 100 days post-transplant. The risks of ARF and mortality after ARF were examined using univariate analysis and multivariate unconditional logistic regression. The correlation of ARF and survival was examined using Cox regression. The results indicated that 27 patients (31.40%) developed ARF at a median of 59.5 days after transplant (range 1 to 93 days). The univariate analysis showed that elevated risks were severe acute GVHD (OR 6.196; 95% CI 1.121 - 34.249, p = 0.033), sepsis or septic shock (OR 4.184; 95% CI 1.314 - 13.325, p = 0.018) and hyperbilirubinemia (OR 3.709; 95% CI 1.428 - 9.635, p = 0.006). Renal disease before transplant (OR 6.711; 95% CI 1.199 - 37.564, p = 0.027), hypertension (OR 2.067; 95% CI 0.739 - 5.782, p = 0.165), the use of vancomycin (OR 2.133; 95% CI 0.844 - 5.392, p = 0.106) or foscarnet sodium (OR 2.133; 95% CI 0.844 - 5.392, p = 0.106) may be potential risks. Multivariate logistic regression analysis showed that renal disease before transplant (OR 6.288; 95% CI 1.218 - 32.455, p = 0.028), sepsis or septic shock (OR 3.614; 95% CI 1.040 - 12.544, p = 0.043) and hyperbilirubinemia (OR 4.448; 95% CI 1.563 - 12.665, p = 0.005) appear to be independently associated with an increased risk of ARF. Age, gender, baseline serum creatinine level, advanced malignant disease, unrelated-donor, total body irradiation (TBI) and cyclosporine levels were not associated with the development of ARF. Cox regression showed that ARF (RR 2.124; 95% CI 1.016 - 4.441, p = 0.045) was independently associated with survival of patients after allo-HSCT. The mortality of patients with ARF within 6 months post-transplant was significantly higher than that of those without ARF (44.4% vs 8.47%, p < 0.001). It is concluded that the cumulative incidence of ARF after allo-HSCT remains high. Renal disease before transplant, hyperbilirubinemia and sepsis or septic shock are all related factors which can increase the risk of ARF. ARF appears to be independent factor influencing survival of patients after allo-HSCT.

OBJECTIVETo observe the engraftment, survival and graft-versus-host disease (GVHD) after 2 units unrelated cord blood (UCB) transplantation for treatment of adult hematological malignancies.

METHODSAmong twelve patients with hematological malignancies, ten were in stable stage and 2 in advanced stage. Conditioning regimen was Bu/Cy or Cy/TBI in 11 cases, and 1 received nonmyeloablative regimen. Antithymocyte globulin (ATG) was administered in all patients. GVHD prophylaxis consisted of cyclosporine A (CsA), mycophenolate mofetil (MMF) and short course methotrexate (MTX). Each patient received 2 units UCB of HLA mismatched at 0 -2 loci. Median total nucleated cells (TNC) infused was 5.55 x 10(7)/kg [range (2.99 -8.18) x 10(7)/kg].

RESULTSOne patient showed primary graft failure. The other 11 patients showed neutrophil engraftment at a mean time of (21.6 +/- 5.1) days and platelet engraftment at (34.9 +/- 9.5) days. One patient showed secondary graft failure and died of leukemia relapse at 3 months after transplantation. Ten patients (83.3%) gained sustained engraftment. In 9 patients the UBC unit with larger TNC dose predominated engraftment, and only 1 patient showed the unit with smaller TNC predominated (P = 0.011). Acute GVHD was observed in 6 patients, including grade I in 5 and grade II in 1. Limited chronic GVHD was observed in 2 of 10 patients survived more than 100 days. Of the total 12 patients, eight were still alive in event-free status and 3-year event-free survival(EFS) was (66.7 +/- 13.6)%. Of the 10 patients in stable stage at the time of transplantation, the probability of EFS was (70.0 +/- 14.5 )%.

CONCLUSIONSTwo UBC units transplantation with HLA mismatched at 0 - 2 loci is feasible as a treatment modality for adult hematological malignancies, and the unit with larger TNC dose would predominate the engraftment.

OBJECTIVETo observe whether rhIL-11 could accelerate the engraftment of platelets after unrelated cord blood transplantation (CBT).

METHODSNine patients (3 children and 6 adults) were enrolled in this study. The degree of HLA disparity was 0-2 loci. Cord blood was given two units for adults and one unit for children. Conditioning regimens were CY/TBI in 1 and BU/CY in 8 cases, both with antithymocyte globulin. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine and short-term methotrexate. On day +1, rhIL-11 was used at 50 microg x kg(-1) x d(-1) and G-CSF at 5 microg x kg(-1) x d(-1) to accelerate hematopoiesis recovery.

RESULTSThe median age of the patients was 22.3 years and the median weight 52.3 kg. Among the 9 patients, 8 (88.9%) experienced engraftment. The median time to neutrophil > 0.5 x 10(9)/L was 21.3 (14-37) days and to platelet > 20 x 10(9)/L was 25 (18-36) days. 42.9% of the patients developed grade I aGVHD and 33.3% developed localized chronic GVHD. Six patients were alive and disease-free at a median follow-up of 7 months. Infection was the primary cause of death. The expected 1-year survival was 77.8%, 2-year survival was 52.2%. Five of 8 patients (62.5%) who received IL-11 presented leakage syndrome. On prophylaxis with drugs containing Arnebia root extract, all patients could tolerate the treatment.

CONCLUSIONrhIL-11 maybe helpful for accelerating the platelet recovery and reducing aGVHD severity in unrelated CBT. The major side effect is leakage syndrome. It is well tolerated on prophylaxis with drugs containing Arnebia root.

This study was purposed to analyze the clinical characteristics and prognostic factors in patients with primary gastrointestinal non-Hodgkin's lymphoma (PGI-NHL). The pathological data of 101 PGI-NHL patients admitted in our hospital in the past 15 years were analyzed retrospectively. The results showed that 101 patients with PGI-NHL accounted for 14.49% of NHL in the same period, there were 64 males, 37 females, the range of ages was from 18 to 87 years old, median age was 61 years old; in disease distribution, the stomach PGI-NHL accounted for 58.42%, intestine PGI-NHL accounted for 39.60%, multiple GI involvements (MGI) accounted for 1.98%; in pathological type, diffuse large B cell lymphoma (DLBCL) accounted for 66.34%, mucosa-associated lymphoid tissue (MALT) lymphoma accounted for 17.82%, mantle cell lymphoma (MCL) accounted for 3.96%, enteropathy-associated T cell lymphoma (EATL) accounted for 7.92%, extra-nodal nasal type NK/T cell lymphoma accounted for 1.98%, follicular lymphoma (FL) accounted for 0.99%, small lymphocyte lymphoma (SLL) accounted for 0.99%. Eighty-nine out of 101 patients were followed up (49 cases live, 40 cases dead), data of the 12 patients were lost; the median survival time was 29 months (1 - 173). The three-year OS and five-year OS were 58.4% and 52.6% respectively. Univariate analysis revealed that the factors affecting OS included sex (P = 0.004), lesion site (P = 0.002), tumor size (P = 0.011), clinical Lugano staging for gastrointestinal non-Hodgkin's lymphoma (P = 0.003), IPI score (P = 0.000), pathological cell phenotype (P = 0.001), and pathological type (P = 0.006), their differences were statistically significant (P < 0.05). Multivariate Cox regression analysis indicated that clinical Lugano staging for gastrointestinal non-Hodgkin's lymphoma, IPI score, pathological type were independent prognostic risk factors affecting OS. It is concluded that clinical Lugano staging for gastrointestinal non-Hodgkin's lymphoma, IPI score and pathological type are independent risk factors affecting OS.

OBJECTIVETo investigate the treatment of primary amyloidosis with high-dose melphalan and autologous hematopoietic stem cell transplantation to further examine the survival, hematologic response, and improvement of amyloid-related organ dysfunction.

METHODSRetrospective analysis of 20 patients with primary amyloidosis treated with autologous hematopoietic stem cell transplantation. The status of major organ function before transplantation, mobilization programs and conditioning regimen as possible risk factors for survival were also investigated.

RESULTSOf 20 cases, 11 out of 15 evaluable cases achieved hematologic response, among them, 6 got complete remission (CR, 40%) and 5 partial remission (PR, 33%). The median onset time was 3.0 months (1.5 - 4.0 months) and 4 months (3 - 5 months), respectively after transplantation. The overall hematologic response was 73%. The 11 hematologic responders also had kidney responses. The median time to achieve kidney response was 3 months (2 - 6 months). The 3-year overall survival of the cohort of cases was 71.4%. The major causes of death were heart failure, renal dysfunction and gastrointestinal bleeding. G-CSF alone could obtain satisfactory mobilization results and most of patients well tolerated to the conditioning regimen of melphalan doses from 140 mg/m(2) to 200 mg/m(2).

CONCLUSIONTreatment of primary amyloidosis with high-dose melphalan followed by autologous peripheral blood stem cell transplantation produced high efficacy. The cardiovascular system involvement, renal dysfunction and the abnormality of coagulation function before transplantation may be the risk factors for survival.

The study was aimed to investigate the incidences and risk factors of acute and chronic graft-versus-host diseases (GVHD) and to clarify their effects on relapse and survival of recipients after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The clinical data of 100 cases of allo-HSCT were retrospectively analyzed. The incidences and risk factors of aGVHD and cGVHD, relapse and survival were studied. The results showed that 31 cases developed aGVHD of II - IV grade (34.4%) and 14 cases developed aGVHD of III - IV grade (17.7%). HLA matched or mismatched did not show significant difference in the development of aGVHD of II - IV grade (p > 0.05). Previous occurrence of aGVHD was the risk factor for cGVHD (HR = 2.303, p = 0.088). The female was a favorable factor for cGVHD (HR = 0.401, p = 0.055). The relapse rate was lower in patients who developed cGVHD. The development of aGVHD of II - IV grade was the risk factor for overall survival (p < 0.05). The mortality of patients with aGVHD of III - IV grade and mortality of patients with aGVHD of 0 - I grade were 81.0% and 35.7% respectively, there was very significant difference between them (p = 0.000). In conclusion, till now GVHD and graft-versus-leukemia (GVL) effect can not be separated. The positive effect of GVL could be counteracted by GVHD-related mortality. It is necessary to prevent and control the development of severe aGVHD. The development of local cGVHD may be beneficial to the long-term disease-free survival of patients after allo-HSCT.
