Abstract
OBJECTIVES To analyze the correlation between dysplastic lineage and type of cytopenia in myelodysplastic syndromes. METHODS We analyzed the correlation between dysplasia and cell count using the data set of our previous morphologic study. RESULTS There were no correlations between dysgranulopoiesis of 10% or more and absolute neutrophil count (ANC). Similarly, hyposegmented mature neutrophils (Pelger) of 10% or more were not related to ANC. Interestingly, the platelet count of patients with dysmegakaryopoiesis (dys Mgk) was higher than that of patients without dys Mgk (dys Mgk ≥10% vs <10%, P = .08; dys Mgk ≥40% vs <40%, P = .02; micromegakaryocytes ≥10% vs <10%, P = .004). CONCLUSIONS Since low cell counts did not correlate with the presence of dysplastic features, we suggest that dysplastic features do not directly relate to apoptosis.

Abstract
A 37-year-old female who presented with pancytopenia in April 2008 was diagnosed with aplastic anemia stage 2 with a normal karyotype. She had a PNH phenotype in her red blood cells (RBC) and granulocytes, and HLA DR15. Her aplastic anemia was deteriorated from stage 2 to stage 3, and she required periodic RBC transfusions. Four months after cyclosporine therapy, the pancytopenia improved and she did not need RBC transfusion. However, three months thereafter, she again required RBC transfusions after developing severe ulcerative colitis. Although mesalazine and steroid pulse therapy improved her ulcerative colitis, her transfusion dependency persisted. Eleven months after the diagnosis of aplastic anemia, equine anti-thymocyte globulin (ATG) and cyclosporine were administered, but no hematological improvement was obtained. Six months after the administration of ATG and cyclosporine, transformation to refractory cytopenia with multilineage dysplasia (RCMD) with 7-monosomy was observed. An allogeneic bone marrow transplant (BMT) from a HLA-identical sibling was performed 23 months after the diagnosis of aplastic anemia. Complete remission of both the aplastic anemia and ulcerative colitis was obtained without medication. Although the relationship between aplastic anemia and ulcerative colitis remains unclear, immunological abnormalities might be involved in the pathogenesis of both disorders because she had PNH phenotype in RBC and HLA DR15 and because allogeneic BMT improved both disorders.

Abstract
We designed a treatment protocol for newly diagnosed adult acute lymphoblastic leukemia (ALL) in the pre-imatinib era, employing intensified consolidation therapy with a total of 330 mg/m² doxorubicin and adopting slightly modified induction and maintenance regimen of the CALGB 8811 study. Of 404 eligible patients (median age 38 years, range 15-64 years), 298 (74%) achieved complete remission (CR). The 5-year overall survival (OS) rate was 32%, and the 5-year disease-free survival (DFS) rate was 33%. Of 256 Philadelphia chromosome (Ph)-negative patients, 208 (81%) achieved CR and the 5-year OS rate was 39%, and 60 of them underwent allogeneic-hematopoietic stem cell transplantation (allo-HSCT) from related or unrelated donors during the first CR, resulting in 63% 5-year OS. Of 116 Ph-positive patients, 65 (56%) achieved CR and the 5-year OS rate was 15%, and 22 of them underwent allo-HSCT from related or unrelated donors during the first CR, resulting in 47% 5-year OS. In Ph-negative patients, multivariate analysis showed that older age, advanced performance status and unfavorable karyotypes were significant poor prognostic factors for OS and higher WBC counts for DFS. The present treatment regimen could not show a better outcome than that of our previous JALSG-ALL93 study for adult ALL.

Abstract
Nilotinib is a second-generation BCR-ABL kinase inhibitor with improved potency and selectivity compared to imatinib. A Phase I/II dose-escalation study was designed to evaluate the efficacy, safety, and pharmacokinetics of nilotinib in Japanese patients with imatinib-resistant or -intolerant Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) or relapsed/refractory Ph+ acute lymphoblastic leukemia (ALL). A total of 34 patients were evaluated in this analysis and had a median duration of drug exposure of 293 (range 13-615) days. All 6 CML-CP patients without complete hematologic response (CHR) at baseline rapidly achieved CHR. A major cytogenetic response was achieved in 94% of patients with CML-CP, including a complete cytogenetic response in 69%. A major molecular response was achieved by 56%. These responses were also observed in patients with CML in advanced stages and Ph+ ALL. Non-hematologic adverse events were mostly mild to moderate. Grade 3 or 4 neutropenia and thrombocytopenia occurred in 50 and 28% of patients, respectively. Overall, the results of this study suggest that nilotinib induced significant responses in imatinib-resistant or -intolerant patients with CML-CP and CML in advanced stages and Ph+ ALL. The results of this study confirmed the efficacy and safety of nilotinib in Japanese patients.

Abstract
A phase 1/2 study was conducted to assess the safety and efficacy of dasatinib in Japanese patients with chronic myelogenous leukemia (CML) or Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+) ALL) resistant or intolerant to imatinib. In phase 1, 18 patients with chronic phase (CP) CML were treated with dasatinib 50, 70, or 90 mg twice daily to evaluate safety. Dasatinib <or= 90 mg twice daily was well tolerated. In phase 2, dasatinib 70 mg was given twice daily to CP-CML patients for 24 weeks and to CML patients in accelerated phase (AP)/blast crisis (BC) or Ph(+) ALL for 12 weeks. In the CP-CML group (n = 30) complete hematologic response was 90% and major cytogenetic response (MCyR) 53%. In the AP/BC-CML group (n = 11) major hematologic response (MaHR) was 64% and MCyR 27%, whereas in the Ph(+) ALL group (n = 13) MaHR was 38% and MCyR 54%. Dasatinib was well tolerated and most of the nonhematologic toxicities were mild or moderate. Dasatinib therapy resulted in high rates of hematologic and cytogenetic response, suggesting that dasatinib is promising as a new treatment for Japanese CML and Ph(+) ALL patients resistant or intolerant to imatinib.

Abstract
The clinical significance of minimal residual disease (MRD) is uncertain in patients with Philadelphia chromosome-positive acute lymphoblastic leukaemia (Ph+ ALL) treated with imatinib-combined chemotherapy. Here we report the results of prospective MRD monitoring in 100 adult patients. Three hundred and sixty-seven follow-up bone marrow samples, collected at predefined time points during a uniform treatment protocol, were analysed for BCR-ABL1 transcripts by quantitative reverse transcription polymerase chain reaction. Ninety-seven patients (97%) achieved complete remission (CR), and the relapse-free survival (RFS) rate was 46% at 3 years. Negative MRD at the end of induction therapy was not associated with longer RFS or a lower relapse rate (P = 0.800 and P = 0.964 respectively). Twenty-nine patients showed MRD elevation during haematological CR. Of these, 10 of the 16 who had undergone allogeneic haematopoietic stem cell transplantation (HSCT) in first CR were alive without relapse at a median of 2.9 years after transplantation, whereas 12 of the 13 who had not undergone allogeneic HSCT experienced a relapse. These results demonstrate that, in Ph+ ALL patients treated with imatinib-combined chemotherapy, rapid molecular response is not associated with a favourable prognosis, and that a single observation of elevated MRD is predictive of subsequent relapse, but allogeneic HSCT can override its adverse effect.

Abstract
To identify factors associated with relapse-free survival (RFS), 80 patients with newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia, enrolled in a phase II study of imatinib-combined chemotherapy, were analyzed. The median follow-up of surviving patients was 26.7 months (maximum, 52.5 months). Twenty-eight out of 77 patients who had achieved CR relapsed. The probability of RFS was 50.5% at 2 years. Multivariate analysis revealed that the presence of secondary chromosome aberrations in addition to t(9;22) at diagnosis constitute an independent predictive value for RFS (p=0.027), and increase the risk of treatment failure by 2.8-fold.

Abstract
We identified a novel gene fusion of ANKRD28 (ankyrin repeat domain 28) on 3p25 to NUP98 on 11p15 in a patient with adult myelodysplastic syndrome/acute myelogenous leukemia. A partially cryptic 3-way translocation, t(3;5;11)(p25;q35;p15), that had initially been supposed to be t(3;5)(p25;q35) was revealed by precise breakpoint mapping via fluorescence in situ hybridization analysis with bacterial artificial chromosome clones. This translocation produces the expression of 2 in-frame fusion transcripts, the novel ANKRD28-NUP98 and NUP98-NSD1, and 1 out-of-frame NSD1-ANKRD28 transcript. Transient overexpression of ANKRD28-NUP98 in NIH/3T3 cells, but not the C-terminal deletion mutant of ANKRD28 (DeltaC-ANKRD28), caused significantly increased focus formation compared with mock-transfectant controls. ANKRD28-NUP98 was localized in the nucleolus and cytoplasm, whereas ANKRD28 and DeltaC-ANKRD28 were found exclusively in the cytoplasm. Alteration of the subcellular localization of ANKRD28 might have contributed to the leukemogenesis in this case. This report is the first of ANKRD28 as an NUP98 fusion partner, and this case implies that this fusion may be responsible for hematologic malignancies.

Abstract
A 60-year-old man was admitted with muscle weakness and numbness in the extremities. Based on the existence of monoclonal gammopathy of the IgG-lamda type, a slight increase of plasma cells in the bone marrow, and an elevated level of serum vascular endothelial growth factor (VEGF), the diagnosis of POEMS syndrome was made. After peripheral blood stem cell collection by etoposide and G-CSF, the patient received high dose melphalan (200 mg/m2) therapy supported by autologous peripheral blood stem cell transplantation (autoPBSCT). After high-dose chemotherapy with autoPBSCT, the serum VEGF level normalized and the monoclonal IgG-lamda, disappeared. The patient gradually recovered from a bedridden state and at the time of writing has no impairment in his activities of daily life. After the autoPBSCT, monoclonal IgG-kappa, protein was detected transiently in serum. The new monoclonal immunoglobulin was considered to be due to normal immune reconstitution after myeloablation rather than alteration of the abnormal plasma cell clone, similarly as oligoclonal immunoglobulins occur in multiple myeloma after autoPBSCT. AutoPBSCT with high-dose chemotherapy should be considered among the treatments of choice for POEMS syndrome.

Abstract
Although biological and clinical features differ between B-lineage acute lymphoblastic leukemia (ALL) and T-lineage ALL (T-ALL), there have been few reports that focused on the prognosis for T-ALL in adults, primarily due to its rarity. Here, we studied the long-term outcomes and prognostic factors specific for adult T-ALL by combining patient data from the three prospective trials conducted by the Japan Adult Leukemia Study Group (JALSG). Among 559 patients whose immunophenotypes could be evaluated, 87 (15.6%) were identified as T-ALL. Of them, 66 patients (75.8%) achieved complete remission, and relapse occurred in 41 patients. With a median follow-up for surviving patients of 7.5 years, the probability of overall survival was 35.0% at 5 years. Risk factor analysis revealed that serum albumin levels, initial white blood cell (WBC) counts, and age had independent values for predicting survival. For WBC, not only the high-count group (50 x 10(9)l(-1) or higher), but also the low-count group (less than 3 x 10(9)l(-1)) showed a significantly lower survival rates than the intermediate-count group (p=0.0055 and 0.0037, respectively). Although our findings need confirmation, these results will be helpful in the identification of prognostically distinct subgroups within adult T-ALL.

Abstract
To evaluate the efficacy of imatinib in a practical setting, we registered 43 patients with newly diagnosed chronic myelogenous leukemia (CML) (group I) and 56 patients with previously diagnosed CML (group II) at 11 hematology centers in Nagasaki prefecture, Japan, from December 2001 to July 2005 and analyzed the molecular responses. Cytopenia, fluid retention, and skin rash were major adverse events, along with elevation in creatine phosphokinase levels. With a follow-up of approximately 3.5 years, imatinib treatment led to 88.7% overall survival (OS) and 85.2% progression-free survival (PFS) rates for group I, and 79.8% OS and 76.6% PFS rates for group II; the rates were not significantly different despite a lower average imatinib dose in group II. The rates of complete cytogenetic response at 30 months and major molecular response at 24 months were 86.1% and 62.5%, respectively, in group I, and 77.9% and 58.3% in group II; the rates were not significantly different. As has been reported by other groups, these results demonstrate that imatinib treatment can provide excellent clinical and molecular effects for not only newly diagnosed but also previously treated CML patients in practical settings that cover a wider variety of patients than clinical trials.
