ABSTRACT
Objective: This study aimed to explore the prognostic value of the revised international prognostic scoring system (IPSS-R) and the WHO prognostic scoring system (WPSS) in patients with myelodysplastic syndrome (MDS) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: The clinical data of 184 patients with MDS who received allo-HSCT from July 2016 to June 2019 were retrospectively analyzed. IPSS-R and WPSS were performed at diagnosis and before transplantation. The prognostic values of IPSS-R and WPSS and potential risk factors were explored. Results: With a median follow-up of 21.9 (0.5-47.5) months, the two-year overall survival (OS) and progression-free survival (PFS) rates were (75.1±3.4)% and (71.6±3.6)% , respectively. The two-year cumulative relapse rate and nonrelapse mortality rate were (11.9±0.1)% and (16.5±0.1)% , respectively. There were no significant differences in OS and PFS between the IPSS-R ≤3.5 and >3.5 groups at diagnosis (P=0.409; P=0.724). No significant differences in OS and PFS between the WPSS ≤2 and >2 groups (P=0.426; P=0.726) were observed as well. When the patients were reevaluated before transplantation, the OS and PFS of the IPSS-R ≤3.5 group were significantly better than >3.5 group [OS: (88.6±4.1)% vs (65.8±5.3)% , P=0.003; PFS: (87.6±4.2)% vs (60.5±5.8)% , P=0.002]. However, there were no significant differences in OS and PFS among the WPSS ≤2 and >2 groups (P=0.584; P=0.565). In addition, the OS and PFS of the improved group based on IPSS-R were significantly better than those of the unimproved group before transplantation [OS: (83.8±4.6)% vs (69.3±5.8)% , P=0.027; PFS: (82.8±4.4)% vs. (64.0±7.2)% , P=0.006]. Multivariate analysis indicated that a pretransplant IPSS-R of >3.5 (P=0.021, HR=2.510, 95% CI 1.151-5.476) and TP53 mutation (P=0.047, HR=2.460, 95% CI 1.014-5.971) were independent risk factors for OS, whereas a pretransplant IPSS-R of >3.5 (P=0.017, HR=2.457, 95% CI 1.175-5.141) and pretransplant cytogenetic poor and very poor (P=0.008, HR=2.765, 95% CI 1.305-5.856) were independent risk factors for PFS. Conclusion: A pretransplantation evaluation of IPSS-R could help determine the prognosis of patients with MDS undergoing allo-HSCT. In addition, patients with improved IPSS-R scores before undergoing allo-HSCT had a better prognosis.

Objective:To evaluate the outcomes and prognostic factors of myelodysplasia syndrome with excess blasts (MDS-EB) patients on intensive chemotherapy or hypomethylating agent treatment prior to allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:A total of 108 MDS-EB patients undergoing allo-HSCT from April 2015 to September 2019 were collected retrospectively, intensive chemotherapy or hypomethylating agent treatment (IC/HAM) group, n=72; support care (SC) group, n=36. Clinical outcomes and prognostic risk factors were analyzed. Results:Intensive chemotherapy or hypomethylating agent treatment pre-HSCT had no effects on overall survival (OS) ( P=0.725), relapse-free survival (RFS)( P=0.658), cumulative incidence rate (CIR) ( P=0.121) or non-relapse mortality (NRM)( P=0.236). Univariate and multivariate analysis of an entire cohort showed that poor cytogenetics was an independent risk factor for OS ( P=0.005), DFS ( P=0.001) and CIR( P=0.032); grade Ⅱ-Ⅳ acute graft venous host disease was independently correlated with unfavorable DFS( P=0.004). Conclusions:IC/HAM treatment pre-HSCT fails to yield discrepant post-HSCT outcomes in MDS-EB patients. The pooling of more patients in a well-designed multi-center clinical trial will further demonstrate the efficacy of treatment pre-HSCT in MDS-EB patients.
ABSTRACT
Objective:To evaluate the prognosis of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for treatment of elderly patients with acute myeloid leukemia (AML).Methods:The clinical data of 53 elderly patients (≥55 years old) with AML who received allo-HSCT in the First Affiliated Hospital of Soochow University from June 2008 to March 2019 were retrospectively analyzed. All the patients included haplo-HSCT (26 cases), matched-sibling donors (MSD)-HSCT (18 cases), matched or mismatched unrelated donors (9 cases). The efficacy of allo-HSCT for elderly patients with AML was analyzed, and the efficacy and safety of haplo-HSCT and MSD-HSCT were compared.Results:There were 35 males and 18 females among 53 elderly AML patients. The median age was 57 years old (55-67 years old), and 45 patients received myeloablative conditioning (MAC) regimen while 8 patients received reduced intensity conditioning (RIC) regimen. There were 52 patients who were successfully implanted in granulocyte, and the median time for engraftment was 12 d (10-23 d). There were 50 patients who were successfully implanted in megakaryocyte and the median time for engraftment was 13 d (10-76 d). The incidence of acute graft-versus-host disease (GVHD) was 49.1% (26/53), and the incidence of grade Ⅲ-Ⅳ acute GVHD was 15.1% (8/53), respectively. The median follow-up time was 14.7 months (0.4-136.8 months), and 32 patients survived. The rate of 2-year overall survival (OS), disease-free survival (DFS) and graft-versus-host-free-relapse free survival (GRFS) was 63.1%, 59.5% and 46.1%, respectively. Multivariate analysis showed that non-complete remission (CR) state before transplantation was an independent prognostic factor for OS ( HR = 3.600, 95% CI 1.213-10.684, P = 0.021), DFS ( HR = 2.596, 95% CI 1.098-6.138, P = 0.030) and relapse ( HR = 3.957, 95% CI 1.099-14.245, P = 0.035). Donor age > 45 years old was an independent risk factor for OS ( HR = 3.687, 95% CI 1.343-10.215, P = 0.011). Time from diagnosis to transplantation ≥6 months was an independent risk factor for GRFS ( HR = 2.308, 95% CI 1.083-4.918, P = 0.030). There were no statistical differences in OS rate, DFS rate, cumulative relapse rate, the incidence of grade Ⅲ-Ⅳ acute GVHD and moderate to severe chronic GVHD between haplo-HSCT and MSD-HSCT (all P > 0.05). Conclusions:The preliminary results show that allo-HSCT is an effective and safe treatment for elderly AML patients. In addition, haplo-HSCT is similar to MSD-HSCT in the efficacy and safety, indicating that haplo-HSCT could be a better treatment option for elderly AML patients under the circumstance without non-identical donor.

ABSTRACT
Objective@#To investigate the prognosis of allogeneic hematopoietic stem-cell transplantation (allo-HSCT) for patients with acute myeloid leukemia and MLL rearrangement.@*Methods@#From September 2009 to May 2016, the clinical data of 47 patients with MLL-rearranged AML undergoing allo-HSCT in the First Affiliated Hospital of Soochow University were retrospectively analyzed.@*Results@#Among 47 MLL-rearranged AML patients, 24 were male and 23 female. The median age was 30 (15-58) years old. There are 36 (76%) patients were FAB-types M4/M5. Two-year overall survival (OS), disease-free survival (DFS), relapse incidence and transplant-related mortality (TRM) were (64.4±8.4)%, (47.3±9.3)%, 41.0% and 17.9%, respectively. Of them, 45 patients were detected with 11q23 translocations, and 2 patients with normal karyotype were MLL partial tandem duplication. According to different chromosome karyotype, 47 patients were divided into three groups: 16 cases of t (6; 11), 15 cases of t (9; 11) and 16 cases of other types. Overall survival was compared between the three groups, there was no significant difference (χ2=1.509, P=0.472). On multivariate analysis, independent risk factor on OS was transplant age >45 years [HR=4.454(95%CI 1.314-15.099), P=0.016]. The multivariate analysis also confirmed the higher TRM in patients at non-CR state when transplanted [HR=10.370(95%CI 1.043-103.110), P=0.046]. Positive minimal residual disease (MRD) before transplantation was a negative prognostic factor on DFS [HR=4.236(95%CI 1.238-14.495), P=0.021] and relapse incidence (RI) [HR=5.491(95%CI 1.371-21.995), P=0.016].@*Conclusion@#Transplant age (>45 years), allo-HSCT in non-CR state adn positive MRD before transplantation were negative prognostic factors in allo-HSCT for MLL-rearranged AML patients.
ABSTRACT
<p><b>OBJECTIVE</b>To discuss the early diagnostic methods and therapeutic principles of aneurysmal subarachnoid hemorrhage (SAH), and evaluate the therapeutic efficacy objectively.</p><p><b>METHODS</b>Using neuro-imaging examinations combined with case history and clinical symptoms to make the early diagnosis of 96 case with aneurysmal SAH, and Guglielmi detachable microcoil (GDC) was utilized for early intracapsular embolization in the ruptured aneurysms. Efficient symptomatic treatment was done early after operation.</p><p><b>RESULTS</b>All of 96 cases were early diagnosed and successfully embolized; Among them, the aneurysmal lumen was 100% occluded in 83 cases, 95% in 8 cases, 90% in 5 cases. There were 3 cases complicating with aneurysms rupture during operation, 5 cases with cerebral vasospasm. One case was affected by microcoil terminal escape after operation, 3 recurrent cases were all cured with secondary GDC embolization. There were 9 complications associated with embolization techniques and 13 cases (13.5%) occurring permanent sequelae associated with SAH. According to the Glasgow prognosis score, 77 patients got grade I, 7 grade II, 6 grade III, 3 grade IV, and 3 grade V. The mortality rate was 3.1%.</p><p><b>CONCLUSIONS</b>To make early etiological diagnosis of the SAH patients, using GDC to embolize the aneurysms, and earlier efficient symptomatic treatment are important methods to improve the curative rate and reduce the mortality rate.</p>
