Abstract
We report the first patient to develop ALL with a fusion gene of the erythropoietin receptor (EPOR) with immunoglobulin heavy chain (IgH) 22 years after a diagnosis of secondary erythrocytosis with unknown etiology. The IgH-EPOR rearrangement is known to induce increased expression of EPOR, and activates EPO-associated signal pathways by exogenous EPO stimulation, resulting in the increased proliferation and survival of IgH-EPOR-positive leukemic cells. Interestingly, this case may provide supporting the possibility that IgH-EPOR-positive ALL has a growth advantage under sustained high concentrations of EPO.

Abstract
The incidence of second primary malignancies (SPMs) in Japanese patients with myeloma or myeloma-related diseases was studied by using the Kansai Myeloma Forum (KMF) database registered from November 2012 to March 2015. We studied 1,571 cases. Hematologic malignancies were documented in 10 patients, and solid tumors in 36 during this period. The cumulative 5-year incidence was estimated to be 1.0% for hematological malignancies and 3.7% for solid tumors. In the patients with smoldering myeloma or MGUS without treatment, solid tumors but not hematologic malignancies developed, though the cumulative incidence of each malignancy did not differ significantly from that in patients receiving treatment. Although statistical analysis showed that treatment with melphalan, bortezomib, lenalidomide, or thalidomide had no effect on the occurrence of hematological malignancies, lenalidomide administration was more frequent in the patients with solid tumors. To evaluate the SPMs in myeloma or myeloma-related diseases more accurately, accumulation of a larger number of patients and longer observation are needed.

Abstract
.ocn.ne.jp. This study measured and compared levels of some chemokines in patients with rituximab-treated non-Hodgkin lymphoma because they may participate in the mechanism of efficacy of rituximab in non-Hodgkin lymphoma patients. Monocytic chemotactant protein-1, RANTES (regulated on activation, normally T-cell expressed and secreted), eotaxin, interleukin-8, neutrophil-activating protein-78, stromal cell-derived factor-1, and growth-regulating oncogene-α in patients with rituximab-treated non-Hodgkin lymphoma were measured by enzyme-linked immunosorbent assay. Levels of RANTES were higher in non-Hodgkin lymphoma patients than in controls. Levels of monocytic chemotactant protein-1, RANTES, and neutrophil-activating protein-78 were significantly elevated before and after chemotherapy with rituximab treatment. However, the level of stromal cell-derived factor-1 did not exhibit a significant change. Before to after chemotherapy without rituximab treatment, all chemokine levels did not exhibit significant changes. These findings suggest that activated platelet-dependent chemokines such as RANTES and neutrophil-activating protein-78 may modulate the efficacy of rituximab in antibody-dependent cellular cytotoxity.

Abstract
Dasatinib, a 2nd-generation tyrosine kinase inhibitor (TKI), can specifically induce large granular lymphocytes (LGL) in some patients with Philadelphia chromosome (Ph)-positive leukemia. To investigate the properties of the induced LGLs, we performed prospective and longitudinal analyses. From Feb 2011 to Jan 2013, a total of 17 patients with Ph-positive leukemia who were previously untreated or refractory to imatinib were enrolled. T cell receptor (TCR)-γ/δ gene rearrangements and phenotypic profiles of lymphocytes were examined before and during administration of dasatinib. LGL lymphocytosis was observed in half of the dasatinib-treated cases (LGL+ group), showing a relation to increased achievement of complete cytogenetic response within 6 months. The phenotypes of the increased lymphocytes were revealed to be mostly natural killer cells. In the LGL+ group, clonal TCR-γ gene rearrangements were frequently detected at diagnosis (six of nine cases) and persisted during therapy, compared with only two of eight in the LGL- group. The proportion of regulatory T cells to CD4+ T cells at diagnosis was lower in the LGL+ compared with the LGL- group (median 4.2 vs. 6.6 %), and this disparity was sustained throughout the therapeutic period. These results demonstrate that immunological condition at diagnosis may affect LGL lymphocytosis in some dasatinib-treated patients.

J Med Case Rep 2015; 9:131. [PMID: 26044457 PMCID: PMC4469000 DOI: 10.1186/s13256-015-0614-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2014] [Accepted: 05/08/2015] [Indexed: 11/18/2022] Open
Abstract
Introduction The most common cause of central pontine myelinolysis is an overly rapid correction of hyponatremia, although it can also occur in patients with any condition leading to nutritional or electrolyte stress. We report a case of diffuse large B-cell lymphoma with central pontine myelinolysis developing at the onset of disease. To the best of our knowledge, hematological malignancies presenting with central pontine myelinolysis have been rarely reported, especially in previously untreated patients, as in our case report. Case presentation A 78-year-old Japanese woman presented to a neighborhood clinic with persistent high fever, edema, and general weakness. Despite the absence of specific neurological findings, brain magnetic resonance imaging showed an abnormal lesion in the central pons area of her brain (hyperintense on T2-weighted and hypointense on T1-weighted sequences), compatible with central pontine myelinolysis. She was admitted to our emergency department in a state of shock one month later. The results of her blood tests showed greatly elevated C-reactive protein and lactate dehydrogenase levels. She had severe hypoalbuminemia and mild hyponatremia, and showed signs of disseminated intravascular coagulation. Mild bilateral pleural effusion, prominent subcutaneous edema, and splenomegaly were detected on her systemic computed tomography scan. Her body fluid cultures did not show signs of infection and her spinal aspiration did not show pleocytosis or abnormal cells. A diagnosis of diffuse large B-cell lymphoma was made based on the results of her bone marrow examination. As she was critically ill before the diagnosis was made, she was treated with methylprednisolone pulse therapy, followed by systemic chemotherapy (rituximab with modified THP-COP regimen, including cyclophosphamide, pirarubicin, vindesine, and prednisolone), which resulted in complete remission and recovery without any neurological defects, and resolution of her abnormal findings on magnetic resonance imaging. Conclusions Central pontine myelinolysis is a serious condition that may result in neuropathological sequelae and mortality, and clinicians should be aware of its potential presence in patients with malignancies.

Abstract
We retrospectively investigated the prognostic factor of lenalidomide plus low-dose dexamethasone (Rd) in Japanese patients with refractory or relapsed multiple myeloma (RRMM) registered in the Kansai Myeloma Forum from January 2006 to December 2013. A total of 140 patients were analyzed. The median age was 66 years. The overall response rate was 68.6 %, including 33.1 % with a better than very good partial response. At 13.0 months median follow-up, the median overall survival (OS) and progression-free survival (PFS) were 34.2 and 17.0 months, respectively. In univariate analyses, patients with one or two prior therapies had significantly longer OS (41.2 vs. 21.5 months; P = 0.002) and PFS (29.0 vs. 13.0 months; P = 0.006) than patients treated with three or more prior therapies. Prior use of thalidomide was associated with significantly shorter PFS (19.0 vs. 16.0 months; P = 0.045). The prior use of bortezomib or high-dose therapy with stem cell transplantation, and the International Staging System had no impact on long-term outcome. Multivariate analysis showed that only the number of prior therapies was a significant predictor of both OS and PFS. Our findings suggest that greater benefit may occur when Rd therapy is used at the first or second relapse in RRMM.

Abstract
We retrospectively investigated clinical outcomes and prognostic factors of 131 patients with transplant-ineligible newly diagnosed multiple myeloma (NDMM) who received melphalan and prednisolone (MP) as first-line therapy from 2006 to 2013. Eighty-one patients received salvage therapies incorporating bortezomib, lenalidomide, and/or thalidomide. The overall response rate to MP was 54.2 %, including 9.2 % of better than very good partial response. With a median follow-up period of 30.2 months, median overall survival (OS) and median time to next treatment (TNT) were 54.4 and 19.0 months, respectively. Univariate analysis revealed that performance status and serum calcium level significantly associated with both OS and TNT, and multivariate analysis revealed that the higher serum calcium level had a significantly unfavorable impact on OS and TNT. Importantly, staging informed by the international staging system (ISS) was not predictive for OS or TNT in the analyzed cohort. Our study revealed that, in the context of first-line MP therapy for NDMM, the salvage therapy incorporating novel agents produced a survival period of >30 months after the initiation of second-line therapy, suggesting that the predictive value of ISS for OS and TNT may be limited in the era of novel agents.

Abstract
BACKGROUND The epidemiology of human herpesvirus 6 (HHV-6) encephalitis after allogeneic hematopoietic cell transplantation (HCT) and its relationship with HHV-6 reactivation have not been sufficiently characterized. METHODS This prospective, multicenter study of 230 allogeneic HCT recipients investigated the epidemiology of HHV-6 reactivation and HHV-6 encephalitis. Plasma HHV-6 DNA load was prospectively evaluated twice weekly until 70 days after HCT. RESULTS Cumulative incidence of positive HHV-6 DNA and high-level HHV-6 reactivation (plasma HHV-6 DNA ≥10(4) copies/mL) at day 70 after HCT was 72.2% and 37.0%, respectively. Multivariate analysis identified myeloablative conditioning (hazard ratio [HR], 1.9; P = .004), umbilical cord blood transplantation (UCBT) (HR, 2.0; P = .003), and male sex (HR, 1.6; P = .04) as risk factors for displaying high-level HHV-6 reactivation. HHV-6 encephalitis occurred in 7 patients, and cumulative incidence at day 70 was 3.0%. None of the144 patients without high-level HHV-6 reactivation and 7 of 86 patients (8.1%) with high-level HHV-6 reactivation developed HHV-6 encephalitis (P = .0009). Prevalence of HHV-6 encephalitis was significantly higher among patients receiving UCBT than in patients with other sources (cumulative incidence at day 70, 7.9% vs 1.2%, P = .008). In each of 7 patients with HHV-6 encephalitis, central nervous system (CNS) symptoms developed concomitant with peak plasma HHV-6 DNA (range, 21 656-433 639 copies/mL). CONCLUSIONS High levels of plasma HHV-6 DNA are associated with higher risk of HHV-6 encephalitis. UCBT is a significant risk factor for HHV-6 encephalitis. HHV-6 encephalitis should be considered if CNS dysfunction develops concomitant to high-level plasma HHV-6 DNA after allogeneic HCT.

Abstract
OBJECTIVE We retrospectively investigated the efficacy and predictive factors for the treatment outcomes of bortezomib plus dexamethasone (BD) as second-line induction therapy prior to high-dose chemotherapy supported by autologous stem cell transplantation (HDT/ASCT) in multiple myeloma (MM) patients. METHODS Sixty-six transplant eligible MM patients treated by the Kyoto Clinical Hematology Study Group between 2006 and 2011 were investigated. Conventional induction chemotherapy, including vincristine, doxorubicin and dexamethasone (VAD) and high-dose dexamethasone (HDD), was used as first-line induction therapy in all patients, seven (10.6%) of whom attained a very good partial response (VGPR). Of the 59 patients who did not attain VGPR with VAD or HDD, 33 were given BD as second-line induction therapy prior to HDT/ASCT. RESULTS Patients not treated with BD induction showed an overall response rate (ORR, i.e., better than partial response) of 85.3% after induction therapy, while the ORR of patients treated with BD induction improved from 42.4% after conventional induction therapy to 84.8% after BD. The overall survival (OS) and progression-free survival (PFS) of patients not treated with BD induction were not significantly influenced by the response to induction therapy. Among the patients treated with BD, failure in attaining VGPR prior to ASCT was associated with a significantly shorter PFS and it also tended to show a shorter OS, while the disease stage and achievement of a complete response after HDT/ASCT had no impact on OS or PFS. CONCLUSION The achievement of at least VGPR with second-line BD induction therapy is a prerequisite for attaining longer OS and PFS after HDT/ASCT.

Abstract
We conducted a retrospective collaborative investigation of bortezomib (Bor) plus dexamethasone (Dex) therapy (BD Tx) for 88 relapsed or refractory (Rel/Ref) MM patients at six institutes. One cycle BD Tx comprised of Bor (1.3 mg/m²/day) on days 1, 4, 8 and 11, and Dex on days 1, 2, 4, 5, 8, 9, 11 and 12, every 21 days, and the mean number of BD Tx cycles was 3. The overall response rate was 66.9%, the median overall survival (OS) was 510 days, and the median progression-free survival (PFS) was 113 days. Attainment of partial response (PR) with the first course of BD Tx associated with the longer OS and PFS and late good responder, while no patient who did not achieve PR with the first cycle attained better than very good PR (VGPR) with the subsequent BD Tx. Patient age of less than 64 years old also associated with the longer OS and PFS. In addition, both an earlier disease stage and Dex dosage had a significant impact on OS, while the attainment of VGPR within 2 cycles had a significantly longer PFS. Earlier BD Tx courses may be predictive for the subsequent therapeutic pathway of Rel/Ref MM.

Abstract
Bendamustine is a unique cytotoxic agent that has demonstrated efficacy in the treatment of indolent B-cell non-Hodgkin lymphomas (B-NHLs). In this multicenter phase II trial, the efficacy and safety of bendamustine were evaluated in Japanese patients with relapsed or refractory indolent B-NHL or mantle-cell lymphoma (MCL). Patients received bendamustine (120 mg/m(2) ) on days 1-2 of a 21-day cycle, for up to six cycles. The primary endpoint was the overall response rate (ORR) as assessed by an extramural committee according to International Workshop Response Criteria (IWRC). Secondary endpoints included complete response (CR) rate, ORR according to Revised Response Criteria (revised RC), progression-free survival (PFS), and safety. Fifty-eight patients with indolent B-NHL and 11 with MCL were enrolled. By IWRC, bendamustine produced an ORR of 91% (95% confidence interval [CI], 82-97%; 90% and 100% in patients with indolent B-NHL and MCL, respectively), with a CR rate of 67% (95% CI, 54-78%). ORR and CR rates according to revised RC were 93% (95% CI, 84-98%) and 57% (95% CI, 44-68%), respectively. After a median follow-up of 12.6 months, median PFS had not been reached. Estimated PFS rates at 1 year were 70% and 90% among indolent B-NHL and MCL patients, respectively. Bendamustine was generally well tolerated. Reversible myelosuppression, including grade 3/4 leukopenia (65%) and neutropenia (72%), was the most clinically significant toxicity observed. Common non-hematologic toxicities included mild gastrointestinal events and fatigue. These results demonstrate the high efficacy and tolerability of single-agent bendamustine in relapsed patients with indolent B-NHL or MCL histologies.

Abstract
The benefits of allogeneic hematopoietic cell transplantation (allo-HCT) for patients with acute myelogenous leukemia (AML) in first complete remission (CR1) have mostly been evaluated in younger patients. Although favorable outcomes of allo-HCT over chemotherapy have been reported with the use of reduced-intensity conditioning (RIC) regimens in elderly patients with AML in CR1, information is still limited, especially on the effects of cytogenetic risks and donor sources. We collected data from AML patients aged 50 to 70 years who achieved CR1, and compared the outcome in 152 patients who underwent allo-HCT in CR1 (HCT group) to that in 884 patients who were treated with chemotherapy (CTx group). The cumulative incidence of relapse in the HCT group was significantly lower than that in the CTx group (22% versus 62%). Both overall survival (OS) and relapse-free survival (RFS) were significantly improved in the HCT group (OS: 62% versus 51%, P = .012), not only in the whole population, but also in the intermediate-risk group. Among patients who had a suitable related donor, the outcomes in the HCT group were significantly better than those in the CTx group. The introduction of appropriate treatment strategies that include allo-HCT may improve the outcome in elderly patients with AML in CR1.

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
Although stem cell transplantation (SCT) is being used for hematopoietic reconstitution following high-dose chemotherapy for malignancy, it involves certain serious transplant-related complications such as graft-versus-host disease (GVHD). Angiopoietins play important roles in angiogenesis. However, the role of angiopoietins after SCT is poorly understood. In this study, 52 patients underwent SCT; 26 patients received allogeneic SCT, while the remaining 26 received autologous SCT. In 48 of 52 patients, levels of angiopoietins, cytokines, and soluble factors were measured by enzyme-linked immunosorbent assay. Soluble Fas ligand (sFasL) and endothelial cell-derived microparticle (EDMP) exhibited significant elevation in the early phase (2-3 weeks) after SCT. In addition, the elevation of interleukin (IL)-6, tumor necrosis factor (TNF)-alpha, and sIL-2 receptor (sIL-2R), which are GVHD markers after allogeneic SCT was observed. The level of angiopoietin (Ang)-2 in allogeneic SCT continued to increase for up to 4 weeks, although the level of Ang-1 did not show significant changes. The patients with high Ang-2 exhibited significant increase of sFasL and EDMP compared with those with low Ang-2. In addition, the patients with high-grade GVHD exhibited a significant increase in Ang-2 compared to patients with low-grade GVHD. In the in vitro experiment using endothelial cells, the suppressive effect of Ang-1 on EDMP generation by TNF-alpha was partially inhibited by the addition of Ang-2. Furthermore, multivariate regression analysis showed that EDMP and sFasL were significant factors in Ang-2 elevation. Our results suggest that Ang-2 generation after allogeneic SCT relates to GVHD.

Abstract
Non-T-cell-depleted HLA-haploidentical hematopoietic stem cell transplantation (SCT) from family members has been reported, but its effectiveness and safety are not fully known. In this study, we examined the outcomes of 83 children and adolescents with nonmalignant (n = 11) or malignant (n = 72) disorders who underwent SCT mismatched at 2 or 3 HLA loci, either from the mother (n = 56), a noninherited maternal antigen (NIMA)-mismatched sibling (n = 14), or the father/a noninherited paternal antigen (NIPA)-mismatched sibling (n = 13). Engraftment was satisfactory. Severe (grade III-IV) acute graft-versushost disease (GVHD) was noted only in malignant disease, with an incidence of 21 of 64 evaluable patients. GVHD prophylaxis with a combination of tacrolimus and methotrexate was significantly associated with a lower risk of severe acute GVHD, compared with other types of prophylaxis (P = .04). Nine of 11 patients with nonmalignant disease and 29 of 72 patients with malignant disease were alive at a median follow-up of 26 months (range, 4-57 months). Outcomes were not significantly different among the 3 donor groups (mother versus NIMA-mismatched sibling versus father/NIPA-mismatched sibling) for the malignancy disorders. Our results indicate that non-T-cell-depleted HLA-haploidentical SCT may be feasible, with appropriate GVHD prophylaxis, for young recipients who lack immediate access to a conventional stem cell source.

Abstract
BACKGROUND Primary lymphomatous effusion is a rare lymphoma that arises in the body cavity and has a peculiar proliferative form, lacking a tumor. This primary lymphomatous effusion includes human herpes virus 8 (HHV8)-related primary effusion lymphoma (PEL) and HHV8-unrelated PEL-like lymphoma. We attempted to clarify the nature of the primary lymphomatous effusion. METHODS Using 'PEL' and 'body cavity-based lymphoma' (BCBL) as key words, reports written in English were collected from PubMed. Primary lymphomatous effusion was defined as BCBL with primary effusion and without tumor at onset. Adding our 2 PEL-like lymphoma cases, each case was studied as to the patients' and lymphomas' characteristics, therapy and survival time. Moreover, each item was compared among four groups according to the presence of HHV8 and HIV. RESULTS In 214 cases investigated, there was no difference in proliferation, but an apparent difference in age, gender, phenotype, effectiveness and prognosis among the four groups. CONCLUSIONS Both PEL and PEL-like lymphoma are thought to be characterized by a peculiar proliferation, regardless of the presence of HHV8. Dividing PEL or PEL-like lymphoma into two subgroups on the basis of HIV presentation might also be appropriate.

Abstract
Stem cell transplantation (SCT) is being used for hematopoietic reconstitution following high-dose chemotherapy for malignancy. Some patients seem to have an imbalance of the immune response after SCT and cytokines are known to regulate this response. Recently, platelets have been shown to contain members of the chemokine family, suggesting a role of platelets as inflammatory cells. We measured and compared levels of platelet activation markers, chemokines, and soluble factors in patients undergoing SCT. IL-8 and GROalpha exhibited a significant elevation in the early phase (1 or 2 weeks) after SCT; this trend was marked after autologous SCT. Furthermore, these levels significantly and positively correlated with the change in G-CSF. In contrast, ENA-78 exhibited a significant elevation in the later phase (3 or 4 weeks) after SCT. In addition, its level negatively correlated with the change in G-CSF. Soluble CD40 ligand and platelet-derived microparticles significantly increased after both auto- and allo-SCT. In addition, ENA-78 positively correlated with the level of platelet-derived microparticles. The increase of RANTES seems to be related to platelet activation, since RANTES was in the dynamic phase similar to soluble CD40 ligand and platelet-derived microparticles. RANTES exhibited changes similar to IL-6, TNFalpha, and soluble IL-2 receptors, which are GVHD markers. Thus, the platelet-derived chemokines ENA-78 and RANTES exhibited particular changes after SCT. Our results suggest that ENA-78 play a role in hematopoietic conditions in which G-CSF is not involved, and RANTES generation after allo-SCT relates to GVHD.

Abstract
Efficacy of reduced-intensity stem-cell transplantation (RIST) for acute lymphoblastic leukemia (ALL) was investigated in 33 patients (median age, 55 years). RIST sources comprised 20 HLA-identical related donors, five HLA-mismatched related, and eight unrelated donors. Six patients had undergone previous transplantation. Disease status at RIST was first remission (n=13), second remission (n=6), and induction failure or relapse (n=14). All patients tolerated preparatory regimens and achieved neutrophil engraftment (median, day 12.5). Acute and chronic graft-versus-host disease (GVHD) developed in 45 and 64%, respectively. Six patients received donor lymphocyte infusion (DLI), for prophylaxis (n=1) or treatment of recurrent ALL (n=5). Nine patients died of transplant-related mortality, with six deaths due to GVHD. The median follow-up of surviving patients was 11.6 months (range, 3.5-37.3 months). The 1-year relapse-free and overall survival rates were 29.8 and 39.6%, respectively. Of the 14 patients transplanted in relapse, five remained relapse free for longer than 6 months. Cumulative rates of progression and progression-free mortality at 3 years were 50.9 and 30.4%, respectively. These findings suggest the presence of a graft-versus-leukemia effect for ALL. RIST for ALL is worth considering for further evaluation.
