ABSTRACT

Objective:To evaluate risk factors and available treatments of extramedullary relapse (EMR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with myeloid leukemia.Methods:A total of 280 patients were retrospectively analyzed from January 2008 to December 2018 in Affiliated Cancer Hospital of Zhengzhou University. Clinical data were collected including disease patterns, pre-transplantation status, chromosome karyotype, conditioning regimen, types of donor, extramedullary disease before transplantation and graft-versus-host disease (GVHD). The log-rank test and Cox proportional hazard model were uesd for univariate analysis and multivariate analysis, respectively.Results:Twenty patients developed EMR (7.14%). The median time of EMR was 7.5 (1-123) months after allo-HSCT. The mortality of EMR was 80% (16/20). Univariate analysis identified disease patterns, second complete remission (CR2) or progressive disease before transplantation, extramedullary disease, abnormal karyotype and conditioning regimen without total body radiation as significant factors correlated to EMR ( P<0.05). Multi-variable analysis revealed that CR2 or progressive disease ( RR=3.468,95% CI 2.189-7.786), abnormal karyotype ( RR=1.494,95% CI 1.020-2.189) and extramedullary disease before transplantation ( RR=8.627,95% CI 3.921-18.452) were independent risk factors of EMR. Conclusions:The clinical outcome of EMR after allo-HSCT is poor.It is crucial to comprehensively assess and identify EMR as early as possible.

ABSTRACT

Objective:To explore the efficacy and prognostic factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of relapsed/refractory acute myeloid leukemia (AML).Methods:The clinical data of 35 patients with relapsed/refractory AML treated with allo-HSCT in the Affiliated Cancer Hospital of Zhengzhou University from June 2011 to October 2018 was retrospectively analyzed. The overall survival (OS), disease-free survival (DFS), graft versus host disease (GVHD) incidence, transplantation related mortality and recurrence rate were calculated, and the risk factors affecting prognosis were analyzed.Results:Hematopoietic reconstitution was obtained in all patients after transplantation. The 100 d incidence of grade Ⅱ-Ⅳ acute GVHD was (22.9±7.7)%, and the 3-year incidence of chronic GVHD was (49.5±10.60)%. The median follow-up time after transplantation was 14.1 months (4.2-89.4 months). In all cases, 18 cases survived (including 16 cases of DFS), and 17 cases died. Fourteen cases relapsed, and the median recurrence time was 4.7 months (2.9-32.4 months). The 3-year OS rate and DFS rate were (44.4±9.3)% and (43.0±9.5)%, respectively. Univariate analysis showed that the non-remission disease before transplantation, poor genetic risk grade before transplantation and recurrence after transplantation were the risk factors for OS (all P < 0.05). The 3-year OS rates in complete remission before transplantation group and non-remission before transplantation group were (63.2±12.0)% and (15.7±12.8)% ( P = 0.025), the 3-year DFS rates were (62.2±12.3)% and (15.3±12.7)% ( P = 0.028), and the 3-year recurrence rates were (28.2±10.7)% and (80.6±15.7)% ( P = 0.057). The 3-year recurrence rate in genetic high-risk group was higher than that in middle-risk group and low-risk group [100.0%, (45.0±12.1)% and (14.3±13.2)%, P = 0.045]. The 3-year tansplantation related mortality was (18.7±7.7)%. Conclusions:Allo-HSCT is an effective method for salvage treatment of relapsed/refractory AML, and recurrence is the main factor affecting survival. Reducing tumor load before transplantation is very important for reducing recurrence and improving curative effect.

ABSTRACT

The efficacy and safety of co-transplantation of unrelated donor peripheral blood stem cells (UD-PBSCs) combined with umbilical cord mesenchymal stem cells (UC-MSCs) in refractory severe aplastic anemia-Ⅱ(RSAA-Ⅱ) were analyzed retrospectively. Fifteen patients with RSAA-Ⅱ underwent UD-PBSCs and UC-MSCs co-transplantation, among whom 14 cases had hematopoietic reconstitution without severe graft versus-host disease (GVHD). The 5-year overall survival rate was 78.57%. Combination of UD-PBSCs and UC-MSCs transplantation could be a safe and effective option for RSAA-Ⅱ.

ABSTRACT

Objective@#To evaluate the efficacy and safety of mesenchymal stem cells in allogeneic hematopoietic stem cell transplantation for patients with refractory severe aplastic anemia (R-SAA) .@*Method@#The clinical data of 25 R-SAA patients receiving co-transplantation of mesenchymal stem cells combined with peripheral blood stem cells from sibling donors (10 cases) and unrelated donors (15 cases) from March 2010 to July 2018 in Zhengzhou University Affiliated Tumor Hospital were retrospectively analyzed. Antithymocyte globulin (ATG) treatment was ineffective/relapsed in 11 cases, and cyclosporine (CsA) treatment ineffective/relapsed in 14 cases.@*Results@#There were 13 male and 12 female among these patients. One patient had a primary graft failure, one patient had a poorly engraftment of platelets, and the remaining 23 patients achieved hematopoietic engraftment. The median time of granulocyte engraftment was 12.5 (10-23) days and 15 (11-25) days for megakaryocyte. Incidences of grade Ⅰ/Ⅱ acute graft-versus-host disease (aGVHD) and chronic graft-versus-host disease (cGVHD) were 37.5% (9/24) and 21.7% (5/23) , respectively. There was no severe GVHD and no severe complications that related to transplantation. 21 of 25 (84%) patients were alive with a median follow-up of 22.9 (1.6-107.8) months. The 5-year overall survival rate after transplantation was (83.6±7.5) %.@*Conclusion@#The combination of mesenchymal stem cells is reliable and safe in the treatment of R-SAA in peripheral blood stem cell transplantation of unrelated donors and sibling donors, which could significantly reduce the incidence of GVHD and severe transplantation-related complications.

ABSTRACT

Objective@#To analyze the efficacy and safety of asparaginase based chemotherapy bridging autologous hematopoietic stem cell transplantation (auto-HSCT) in the treatment of 16 patients with nasal type extranodal NK/T-cell lymphoma (ENKTL).@*Methods@#From January 2012 to June 2017, 16 patients with nasal type extranodal NK/T-cell lymphoma reached complete remission by L-asparaginase based regimens, and then received auto-HSCT.@*Results@#①Of the 16 patients, 12 were males and 4 females, with a median age of 35.5 (14-61) years. There were 11 patients in the first complete remission (CR1) and 5 in the second CR (CR2) before transplantation, respectively. EB virus (EBV) DNA (EBV-DNA) was negative and positive in 13 and 3 cases respectively before transplantation. ②Hematopoietic reconstitution was achieved in all 16 cases. The median time for neutrophils implantation was 12 (8-17) days, and that of platelet implantation was 15.5 (12-24) days. ③To the last follow-up, there were no transplant related deaths, 3 patients died of disease progression. The median overall survival (OS) time and progression-free survival time (PFS) were not reached. Seven patients lived with no disease progression more than 2 years. ④The OS and PFS of patients at CR1 before auto-HSCT are better than that of patients at CR2, but there was no statistically significant difference (P=0.162, P=0.123). There was no significant difference in OS and PFS between EBV-DNA negative and positive patients before transplantation (P=0.280, P=0.244).@*Conclusions@#L-asparaginase based regimens bridging auto-HSCT is a safe and highly effective for advanced-stage and relapsed ENKTL treatment.

ABSTRACT

Objective@#To explore the occurrence, clinical characteristics, diagnosis and treatment of glomerulitis after allogeneic hematopoietic stem cell transplantation (allo-HSCT).@*Methods@#Analysis were carried out based on the clinical data of 6 patients with de novo glomerulitis following allo-HSCT hospitalized in Henan Tumor Hospital from January 2008 to December 2016, and the clinical manifestation, pathology, diagnosis, treatment and outcome were investigated.@*Results@#The occurrence of glomerulitis was 1.26% (6/478). The median time was 447(272-1 495) d after allo-HSCT. Proteinuria and varying degrees of edema were present in all patients. Of the 6 patients, 4 patients with impaired renal function, 3 cases of hypertension, 5 cases of urine occult blood positive, 2 cases of hyperlipidemia. 5 patients underwent acute graft-versus-host disease (GVHD), 4 patients accompanied with chronic GVHD at diagnosis. Kidney pathology showed typical features of minimal change diseases in 1 patient, membranous nephropathy in 4 patients and mesangial proliferative glomerulonephritis in 1 case. Immunohistochemistry of glomerular lesions revealed that the immune complex deposition included IgG in 4 patients, C3 in 3 patients, IgM and C1q in 1 patient. Serum ANA was positive in 2 patients and serum IgG and IgM were in high level in 1 patient, respectively. Only 1 case was effective on glucocorticoid. 5 cases treated by low dose cyclophosphamide combined with mycophenolate mofetil (MMF), 2 cases achieved complete remission, and 3 cases were partial remission. Up to now, 2 cases died with lung infection, and 4 patients survived.@*Conclusion@#The predominant pathological type of glomerulitis was membranous nephropathy. Low-dose cyclophosphamide combined with MMF was an effective treatment.

ABSTRACT

Objective@#To evaluate the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) from different donors as first-line treatment for children and adolescents with severe aplastic anemia (SAA) .@*Methods@#The clinical data of 79 children and adolescents with SAA diagnosed from January 2013 to December 2016 in Henan Province were retrospectively analyzed. There were 50 males and 29 females, with a median age of 14(4-18) years. 40 cases received matched sibling transplantation (MSD-HSCT), 17 with unrelated donor transplantation (UD-HSCT), and 22 with haploidentical transplantation (haplo-HSCT).@*Results@#The comparison of MSD-HSCT, UD-HSCT, haplo-HSCT groups was conducted and the median times of neutrophils engraftment were statistically significant [12(9-25) d, 14(10-22) d, 16(11-26) d, respectively (χ2=13.302, P=0.001)], but no difference in+30 d engraftment rate [97.3%(36/37), 100%(15/15), 100%(20/20), χ2=0.959, P=0.619]. The median times of PLT engraftment were not statistically significant [14(6-34)d, 16(7-32)d, 19(10-34)d, respectively, χ2=5.892, P=0.053], and the +30 d engraftment rate had no difference [97.3%(36/37), 100%(15/15), 100%(20/20), χ2=0.959, P=0.619]. The post-transplant infection rate showed no statistically significance [35.0% (14/40), 29.4% (5/17), 45.5% (10/22), χ2=1.158, P=0.560], as well as the incidences of aGVHD, grade III/IV aGVHD and cGVHD(χ2=0.230, P=0.891; χ2=2.628, P=0.269; χ2=3.187, P=0.203). The two-years OS rate was not statistically significant respectively [(77.1±6.7)%, (70.6±11.1)%, (77.3±8.9)%, χ2=0.330, P=0.845]. Severe post-transplant infection (RR=4.617, P=0.009), grade Ⅲ/Ⅳ aGVHD (RR=2.707, P=0.048) were independent risk factors for OS.@*Conclusion@#The overall efficacy of MSD-HSCT, UD-HSCT and haplo-HSCT as first-line therapy for children and adolescents with SAA/VSAA is comparable.

ABSTRACT

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective way to acute myeloid leukemia (AML).The therapy effect of allo-HSCT comes from the preconditioning of the radiation and/or chemotherapy,as well as the graft versus leukemia (GVL) effect of the donor' s immune system.In nearly a decade,with the deepening research on biological characteristics of leukemia cells,according to the cytogenetic and molecular markers to dangerous degree classification of AML,which enables us to pick out AML patients can benefit from allo-HSCT.The clinical curative effect of allo-HSCT for AML has obviously improved,and applicable scope has also extended,but there are some differences in the application of AML.The mechanism,opportunity,curative effects,donor selection and preconditioning of allo-HSCT for AML are discussed.

ABSTRACT

Objective To explore the effective treatment with regimen of remission induction for relapsed/refractory precursor lymphocytic leukemia/lymphoma patients. Methods 6 patients with relapsed/refractory precursor lymphocytic leukemia/lymphoma including 2 acute lymphocytic leukemia, 4 lymphoblast lymphoma and 1 hybrid acute leukemia were treated by combination of CAG regimen with L-asparaginase (L-Asp) and prednisone (PDN). Results All patients responded to the regimen, in which 6/7 (85.7 %)patients achieved complete remission and 1/7 (14.3 %) patient achieved partial remission after one course.Light adverse events coursed by the regimen could be tolerated. Conclusion The regimen consisting of CAG, PDN and L-Asp is worth exploring for relapsed/refractory precursor lymphocytic leukemia/lymphoma.

ABSTRACT

ObjectiveTo investigate the clinical characteristics in ABO-incompatible allogeneic peripheral blood stem cell transplantation(allo-PBSCT).Methods137 patients'clinical courses who accepted allo-PBSCT were retrospectively reviewed. Sixty-five cases of them were ABO-incompatible allo-PBSCT patients,including 32 ABO major mismatched cases,23 ABO minor mismatched cases and 10 ABO major and minor mismatched cases.Seventy-two ABO-identical cases were taken as control group.ResultsCompared with ABO-idential cases,the time of erythrocyte recovery after allo-PBSCT in ABO major and minor mismatched group was delayed [(73.2+10.3) d vs (97.5+10.4) d] (P <0.05).In ABO-incompatible group, the time of blood type switching in different ABO-incompatible types were found no significant difference (P >0.05) [ABO major mismatched:(45.7±17.3) d,ABO minor mismatched:(41.2+16.1) d and ABO major and minor mismatched:(48.4±20.9) d (P > 0.05)].There were 8 cases who have a delayed time of blood type changing, including 6 cases demonstrated recipient-derived anti-A antibody. ConclusionABO-incompatible has no negative effect on allo-PBSCT.The time of erythrocyte reconstitution was delayed in ABO major and minor mismatched group.A delayed time of blood type switching tends to occur in ABO minor incompatible cases and patients who have anti-A antibody initially.
