Abstract
BACKGROUND Hypomethylating agents, including azacytidine (AZA), are standard therapeutics for patients with high-risk myelodysplastic syndromes (MDS), a group of myeloid neoplasms. However, treatment schedules are not unified in real-world practice; in addition to the standard 7-day (standard-dose) schedule, shortened (reduced-dose) schedules are also used. AIMS The aim of this study was to discover the patient group(s) which show differential efficacy between standard-and reduced-dose AZA to MDS. METHODS AND RESULTS The outcome of different AZA doses in a cohort of 151 MDS patients were retrospectively analyzed. Overall survival (OS) was not significantly different between standard- and reduced-dose AZA groups by multivariate analysis. However, an interaction was found between either the sex (female vs. male), the platelet counts (< 40 × 103 /μl vs. ≥ 40 × 103 /μl), or the karyotype risk (< poor vs. ≥ poor) and standard-dose AZA for longer OS. Subgroup analyses revealed better OS with standard- over reduced-dose AZA in female patients (HR, 0.27 [95% CI, 0.090-0.79]; p = 0.011), and those with platelet counts ≥ 40 × 103 /μl (HR, 0.51 [95% CI, 0.26-0.99]; p = 0.041). The union of female and preserved platelet count subgroups also benefited from standard-dose AZA. With this as a test cohort, we next analyzed patients registered in the JALSG MDS212 study, for whom 7-day and 5-day AZA treatment strategies were prospectively compared, as a validation cohort (N = 172). That cohort showed the same tendency as the retrospective results. CONCLUSION We identified the union of female and preserved platelet count subgroups which benefited from standard-dose AZA, imparting crucial information to physicians planning treatment regimens in MDS patients.

Abstract
Azacitidine is a mainstay of therapy for myelodysplastic syndrome (MDS)-related diseases. The purpose of our study is to elucidate the effect of gene mutations on hematological response and overall survival (OS), particularly focusing on their posttreatment clone size. We enrolled a total of 449 patients with MDS or related myeloid neoplasms. They were analyzed for gene mutations in pretreatment (n = 449) and posttreatment (n = 289) bone marrow samples using targeted-capture sequencing to assess the impact of gene mutations and their posttreatment clone size on treatment outcomes. In Cox proportional hazard modeling, multihit TP53 mutation (hazard ratio [HR], 2.03; 95% confidence interval [CI], 1.42-2.91; P < .001), EZH2 mutation (HR, 1.71; 95% CI, 1.14-2.54; P = .009), and DDX41 mutation (HR, 0.33; 95% CI, 0.17-0.62; P < .001), together with age, high-risk karyotypes, low platelets, and high blast counts, independently predicted OS. Posttreatment clone size accounting for all drivers significantly correlated with International Working Group (IWG) response (P < .001, using trend test), except for that of DDX41-mutated clones, which did not predict IWG response. Combined, IWG response and posttreatment clone size further improved the prediction of the original model and even that of a recently proposed molecular prediction model, the molecular International Prognostic Scoring System (IPSS-M; c-index, 0.653 vs 0.688; P < .001, using likelihood ratio test). In conclusion, evaluation of posttreatment clone size, together with the pretreatment mutational profile as well as the IWG response play a role in better prognostication of azacitidine-treated patients with myelodysplasia.

Abstract
Vanishing bile duct syndrome (VBDS) is a rare hepatic disorder which leads to liver failure as a result of progressive destruction of the intrahepatic bile ducts. There are no treatment modalities for VBDS itself and severe hepatic dysfunction restricts the treatment of underlying diseases. We safely treated a case of classic Hodgkin lymphoma (HL) with VBDS using brentuximab vedotin (BV). The patient was treated with 5 cycles of reduced BV and a partial metabolic response was obtained. Moreover, a standard dose of BV for another 5 cycles was accomplished with minimal adverse events. Our experience indicates that BV could be a treatment option for classic HL with VBDS.

Abstract
Objective Graft failure (GF) is a life-threatening complication of hematopoietic stem cell transplantation (HSCT). A standardized conditioning regimen and an appropriate graft source of salvage HSCT for GF have not yet been established. Some case series have shown good hematopoietic recoveries after salvage HSCT using a short-term reduced-intensity preparative regimen consisting of fludarabine (30-90 mg/m2), cyclophosphamide (2 g/m2), and total-body irradiation (2 Gy). However, the dose of fludarabine has varied in these reports based on the clinical condition of the patients, resulting in very limited experiences with each dose of fludarabine. Methods We retrospectively analyzed 10 patients who developed GF after allogeneic HSCT and underwent salvage cord blood transplantation (CBT) using the above-mentioned conditioning regimen with a fixed dose (90 mg/m2) of fludarabine. Results Eight patients (80.0%) achieved neutrophil engraftment within 30 days from salvage HSCT with a median of 21 (range, 17-23) days. The 1-year overall survival (OS) rate after the salvage HSCT was 50.0%, and the median OS was 281 (range, 23-1,638) days. Cumulative incidences of non-relapse mortality and relapse at 1 year were 50.0% and 10.0%, respectively. Conclusion CBT using this short-term reduced-intensity conditioning regimen may be a promising salvage therapy for GF.

Abstract
Bing-Neel syndrome (BNS), which presents with a variety of neurological complications, is a rare manifestation of the lymphoplasmacytic lymphoma (LPL) and is characterized by the infiltration of LPL cells into the central nervous system. In this study, we report the case of a patient with BNS, which was confirmed by detecting MYD88 L265P mutation in the cerebrospinal fluid (CSF) cells. A 74-year-old patient was diagnosed with IgG-variant LPL. He achieved a very good partial response to the treatment with rituximab and bendamustine (RB) and was stable for over 5 years, when presenting a slowly progressive motor deficit in the lower limbs. It was difficult to confirm BNS from morphological analysis of the CSF cells. After detecting MYD88 L265P mutation in the CSF cells, he was subsequently diagnosed with BNS and treated with RB and intrathecal chemotherapy, resulting in rapid clinical improvement. With the onset of neurological manifestation during the clinical course of LPL, the detection of MYD88 L265P mutation in the CSF cells could be helpful for the diagnosis and management of BNS.

Abstract
Other iatrogenic immunodeficiency‐associated lymphoproliferative disorders (OIIA‐LPDs) occur in patients receiving immunosuppressive drugs for autoimmune diseases; however, their clinicopathological and genetic features remain unknown. In the present study, we analysed 67 patients with OIIA‐LPDs, including 36 with diffuse large B‐cell lymphoma (DLBCL)‐type and 19 with Hodgkin lymphoma (HL)‐type. After discontinuation of immunosuppressive drugs, regression without relapse was achieved in 22 of 58 patients. Spontaneous regression was associated with Epstein–Barr virus positivity in DLBCL‐type (P = 0·013). The 2‐year overall survival and progression‐free survival (PFS) at a median follow‐up of 32·4 months were 92·7% and 72·1% respectively. Furthermore, a significant difference in the 2‐year PFS was seen between patients with DLBCL‐type and HL‐type OIIA‐LPDs (81·0% vs. 40·9% respectively, P = 0·021). In targeted sequencing of 47 genes in tumour‐derived DNA from 20 DLBCL‐type OIIA‐LPD samples, histone‐lysine N‐methyltransferase 2D (KMT2D; eight, 40%) and tumour necrosis factor receptor superfamily member 14 (TNFRSF14; six, 30%) were the most frequently mutated genes. TNF alpha‐induced protein 3 (TNFAIP3) mutations were present in four patients (20%) with DLBCL‐type OIIA‐LPD. Cases with DLBCL‐type OIIA‐LPD harbouring TNFAIP3 mutations had shorter PFS and required early initiation of first chemotherapy. There were no significant factors for spontaneous regression or response rates according to the presence of mutations. Overall, OIIA‐LPDs, especially DLBCL‐types, showed favourable prognoses.

Abstract
Cytokine release syndrome (CRS), occurring in more than 70% of HLA-haploidentical hematopoietic stem-cell transplantations with post-transplant cyclophosphamide (PT/CY-haplo), can lead to hemodynamic instability and worsen clinical outcomes. A calcineurin inhibitor is initiated after cyclophosphamide administration in the commonly used PT/CY regimens. Here, we conducted a phase I/II, prospective, single-center trial of PT/CY-haplo to evaluate the safety and efficacy of cyclophosphamide on days 3 and 5 along with cyclosporin and mycophenolate mofetil started from day - 1. Thirty-five adults with hematologic malignancies were enrolled. Myeloablative and reduced-intensity conditioning were used in 25 and 10 patients, respectively. Graft sources were bone marrow in 11 patients and mobilized peripheral blood stem cells in 24 patients. Disease-free survival on day 100, the primary endpoint, was 86% (95% confidence interval (CI), 69-94), which was over the predefined threshold of 50%. Unexpectedly, only 20% (95% CI, 8.4-37) of patients developed fever of > 38 °C early after graft infusion, all CRS grade 1, and all of which resolved just after cyclophosphamide administration. The cumulative incidences of grades II-IV acute graft-versus-host disease (GVHD), III-IV acute GVHD, and moderate-severe chronic GVHD were 23% (95% CI, 11-38), 6% (95% CI, 1-17), and 11% (95% CI, 4-25), respectively. The 3-year overall survival rate was 49% (95% CI, 31-64). Our results suggest that administration of cyclosporine and mycophenolate mofetil prior to PT/CY can reduce the frequency and severity of CRS without increasing GVHD. UMIN Clinical Trial Registry numbers: 000006631 and 000015694.

Abstract
A 50-year-old man demonstrated markedly increased number of white blood cells, anemia, severe splenomegaly, and bleeding tendency. Bone marrow analysis revealed remarkable hypercellularity; dysplasia in multilineage cells, including megakaryocytes; and fibrosis. He was eventually diagnosed with triple-negative myelofibrosis. A massive hematoma developed at the bone marrow biopsy site. A similar episode recurred after the second bone marrow biopsy. The von Willebrand factor and other coagulation factor activities were within normal ranges. Platelet aggregation analyses demonstrated highly impaired aggregation induced by ADP, collagen, and epinephrine. Treatment with hydroxyurea and ruxolitinib, a JAK inhibitor, was ineffective, and he eventually died on day 144 after hospitalization. Acquired platelet dysfunction uncommonly occurs in patients with myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN), without precise elucidation of the frequency and underlying mechanism. The onset of bleeding tendency in the current patient suggested that platelet dysfunction may be caused by somatic genetic events. Here, we discuss the mechanisms of acquired platelet dysfunction in MDS or MPN with a literature review.

Abstract
Immunosuppressive therapy (IST) is the first-line treatment for young patients with severe aplastic anemia (AA) when a human leucocyte antigen (HLA)-matched related donor (MRD) is unavailable. Fulminant AA (FAA) is defined as AA with a complete absence of neutrophils at presentation and no response to granulocyte-colony stimulating factor (G-CSF) treatment. Here we report a 38-year-old male FAA patient who underwent allogeneic stem cell transplantation from an HLA haplotype-mismatched donor as first-line treatment. The patient had no remarkable disease history and was referred to our hospital because of a peritonsillar abscess and severe pancytopenia. Bone marrow biopsy revealed marked hypocellularity without dysplasia. His neutrophil count remained 0.0×109/l following G-CSF administration, and he was diagnosed with FAA. His siblings were not MRDs, but his sister had haploidentical HLAs. After administering a conditioning regimen, the patient received a transplant of peripheral blood stem cells donated by his sister. Neutrophil engraftment was observed on post-transplant day 16, and he experienced acute graft-versus-host disease (grade I, skin stage 1), but no other complications were observed. Hematopoietic stem cell transplantation from an HLA haplotype-mismatched related donor may be a viable option for first-line treatment of FAA when an MRD is unavailable.

Abstract
A 46-year-old man who had previously undergone open surgery for renal cell carcinoma (RCC) developed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph-ALL). After the induction therapy, he achieved complete molecular remission. However, fever and bilateral buttock pain continued during the consolidation therapy. 18F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) showed FDG accumulation in both iliac bones and in the sacrum; however, no causative diseases, including relapse of Ph-ALL and RCC, were detected. Iliac bone marrow biopsy revealed bone marrow necrosis (BMN), the etiology of which was presumed to be the leukemia itself and the therapeutic response to chemotherapy. Fever resolution and buttock pain alleviation were observed over the next months. We observed diffuse fibrosis in the bone marrow at day 162 and day 364 after cord blood transplantation. Moreover, the FDG accumulation was significantly reduced on PET-CT. BMN is not widely recognized despite its potential association with hematologic malignancies. Additional cases of BMN should be reviewed to clarify BMN etiology and clinical features.

Abstract
Recurrent hotspot (p.Gly17Val) mutations in RHOA encoding a small GTPase, together with loss-of-function mutations in TET2 encoding an epigenetic regulator, are genetic hallmarks of angioimmunoblastic T-cell lymphoma (AITL). Mice expressing the p.Gly17Val RHOA mutant on a Tet2-null background succumbed to AITL-like T-cell lymphomas due to deregulated T-cell receptor (TCR) signaling. Using these mice to investigate therapeutics for AITL, we found that dasatinib, a multikinase inhibitor prolonged their survival through inhibition of hyperactivated TCR signaling. A phase I clinical trial study of dasatinib monotherapy in 5 patients with relapsed/refractory AITL was performed. Dasatinib was started at a dose of 100 mg/body once a day and continued until days 10-78 (median day 58). All the evaluable patients achieved partial responses. Our findings suggest that AITL is highly dependent on TCR signaling and that dasatinib could be a promising candidate drug for AITL treatment. SIGNIFICANCE: Deregulated T-cell receptor signaling is a critical molecular event in angioimmunoblastic T-cell lymphoma and can be targeted with dasatinib.

Abstract
The transcription factor MafB is specifically expressed in macrophages. We have recently demonstrated that MafB is expressed in anti-inflammatory alternatively activated M2 macrophages in vitro. Tumor-associated macrophages (TAMs) are a subset of M2 type macrophages that can promote immunosuppressive activity, induce angiogenesis, and promote tumor cell proliferation. To examine whether MafB express in TAMs, we analyzed green fluorescent protein (GFP) expression in Lewis lung carcinoma tumors of MafB-GFP knock-in heterozygous mice. FACS analysis demonstrated GFP fluorescence in cells positive for macrophage-markers (F4/80, CD11b, CD68, and CD204). Moreover, quantitative RT-PCR analysis with F4/80+GFP+ and F4/80+GFP- sorted cells showed that the GFP-positive macrophages express IL-10, Arg-1, and TNF-α, which were known to be expressed in TAMs. These results indicate that MafB is expressed in TAMs. Furthermore, immunostaining analysis using an anti-MAFB antibody revealed that MAFB is expressed in CD204-and CD68-positive macrophages in human lung cancer samples. In conclusion, MafB can be a suitable marker of TAMs in both mouse and human tumor tissues.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common histologic subtype of non-Hodgkin lymphoma and is notorious for its clinical heterogeneity. Patient outcomes can be predicted by cell-of-origin (COO) classification, demonstrating that the underlying transcriptional signature of malignant B-cells informs biological behavior in the context of standard combination chemotherapy regimens. In the current study, we used mass cytometry (CyTOF) to examine tumor phenotypes at the protein level with single cell resolution in a collection of 27 diagnostic DLBCL biopsy specimens from treatment naïve patients. We found that malignant B-cells from each patient occupied unique regions in 37-dimensional phenotypic space with no apparent clustering of samples into discrete subtypes. Interestingly, variable MHC class II expression was found to be the greatest contributor to phenotypic diversity. Within individual tumors, a subset of cases showed multiple phenotypic subpopulations, and in one case, we were able to demonstrate direct correspondence between protein-level phenotypic subsets and DNA mutation-defined subclones. In summary, CyTOF analysis can resolve both intertumoral and intratumoral heterogeneity among primary samples and reveals that each case of DLBCL is unique and may be comprised of multiple, genetically distinct subclones. © 2019 International Society for Advancement of Cytometry.

Abstract
Cell-free DNA (cfDNA) analysis to detect circulating tumor DNA has been focused on monitoring malignant lymphomas. However, clonal hematopoiesis of indeterminate potential (CHIP)-associated mutations can also be detected by cfDNA analysis. Our aim is to investigate the origin of mutations detected in cfDNA among B-cell lymphoma patients. MYD88/CD79B, DNMT3A, and TP53 were chosen as genes of interest, representing each of the following categories: lymphoma driver genes, CHIP-related genes, and genes shared between lymphoma and CHIP. Seventy-five B-cell lymphoma patients were included in this retrospective study. Serum cfDNAs at time of complete metabolic response (CMR) were sequenced for TP53 (N = 75) and DNMT3A (N = 49). MYD88 p.L265P and CD79B p.Y196C/H mutations were analyzed in diffuse large B-cell lymphoma (DLBCL) patients whose tumor samples were available (N = 29). Two and seven mutations in TP53 and DNMT3A, respectively, were detected in cfDNA at CMR. These mutations were detected in either bone marrow mononuclear cells (BMMC) or PBMC. Although four DNMT3A mutations were also detected in tumors, median variant allele frequencies in the tumors (<1.0%) were significantly lower than those in both BMMC (6.1%) and serum (5.2%) obtained before the therapy. Conversely, five MYD88 and three CD79B mutations detected in tumors were confirmed in cfDNA before therapy, but not in BMMC nor in cfDNA at CMR. Thus, all TP53 and DNMT3A mutations detected in cfDNA at remission seemed to originate from CHIP rather than from residual disease. Results of liquid biopsy should be carefully interpreted, especially in genes shared between lymphomas and CHIP.

Abstract
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare disease that develops with a skin lesion and is often accompanied by leukemic transformation. The normal counterparts of BPDCN tumor cells are progenitors of plasmacytoid dendritic cells, whereas the origins are thought to be hematopoietic stem cells. Approximately 10%-20% of BPDCN patients develop other hematologic malignancies, including chronic myelomonocytic leukemia (CMML). Mutations in epigenetic regulators are frequently observed in both BPDCN and CMML tumors. Azacitidine, a drug that targets epigenetic dysregulation, is known to be an effective treatment for CMML. However, it has been used in few BPDCN patients. Here, we report a BPDCN patient with skin lesions, bone marrow infiltration, and lymphadenopathy. CMML also developed during the course of BPDCN. Azacitidine had positive effects on CMML; however, BPDCN aggressively relapsed during treatment. Two TET2 mutations were found in both BPDCN and CMML tumors; one of which was commonly identified in both tumors.

Abstract
A 66-year-old male undergoing maintenance hemodialysis presented with mild thrombocytopenia. He also had aortic valve stenosis and required aortic valve replacement. In addition, he required anticoagulation therapy with warfarin because of chronic subclavian artery occlusion. He was eventually diagnosed with immune thrombocytopenic purpura (ITP), although there were no bleeding tendencies. The patient was preoperatively treated with thrombopoietin receptor agonist (romiplostim®) because of the risk of bleeding complication during cardiac surgery. The platelet count rapidly increased with low-dose romiplostim, and no thrombotic complication occurred. During surgery, no significant bleeding complications were observed. This report suggests that romiplostim is a useful treatment option for the management of bleeding complication during cardiac surgery in a hemodialysis patient with ITP.

Abstract
Primary central nervous system lymphoma (PCNSL) is a rare subtype of lymphoma that arises within the brain or the eyes. PCNSL recurs within the central nervous system (CNS) in most relapsed cases, whereas extra‐CNS relapse is experienced in rare cases. The present study aimed at identifying the presence of common precursor cells (CPC) for primary intra‐ and relapsed extra‐CNS tumors, and further assessing the initiating events in bone marrow (BM). Targeted deep sequencing was carried out for five paired primary intra‐ and relapsed extra‐CNS tumors of PCNSL. Two to five mutations were shared by each pair of intra‐ and extra‐CNS tumors. In particular, MYD88 mutations, L265P in three and P258L in one, were shared by four pairs. Unique somatic mutations were observed in all five intra‐CNS tumors and in four out of five extra‐CNS tumors. Remarkably, IgH clones in the intra‐ and the extra‐CNS tumors in two pairs were distinct from each other, whereas one pair of tumors shared identical monoclonal IgH rearrangement. In a cohort of 23 PCNSL patients, L265P MYD88 mutations were examined in tumor‐free BM mononuclear cells (MNC) in which the PCNSL tumors had L265P MYD88 mutations. L265P MYD88 mutations were detected by a droplet digital PCR method in nine out of 23 bone marrow mononuclear cells. These results suggest that intra‐ and extra‐tumors are derived from CPC with MYD88 mutations in most PCNSL, arising either before or after IgH rearrangement. The initiating MYD88 mutations may occur during B‐cell differentiation in BM.

Abstract
Angioimmunoblastic T‐cell lymphoma (AITL) is a subtype of nodal peripheral T‐cell lymphoma (PTCL). Somatic RHOA mutations, most frequently found at the hotspot site c.50G > T, p.Gly17Val (G17V RHOA mutation) are a genetic hallmark of AITL. Detection of the G17V RHOA mutations assists prompt and appropriate diagnosis of AITL. However, an optimal detection method for the G17V RHOA mutation remains to be elucidated. We compared the sensitivity and concordance of next‐generation sequencing (NGS), droplet digital PCR (ddPCR) and peptide nucleic acid‐locked nucleic acid (PNA‐LNA) clamp method for detecting the G17V RHOA mutation. G17V RHOA mutations were identified in 27 of 67 (40.3%) PTCL samples using NGS. ddPCR and PNA‐LNA clamp method both detected G17V mutations in 4 samples in addition to those detected with NGS (31 of 67, 46.3%). Additionally, variant allele frequencies with ddPCR and those with NGS showed high concordance (P < .001). Three other RHOA mutations involving the p.Gly17 position (c.[49G > T;50G > T], p.Gly17Leu in PTCL198; c.[50G > T;51A > C], p.Gly17Val in PTCL216; and c.50G > A, p.Gly17Glu in PTCL223) were detected using NGS. These sequence changes could not appropriately be detected using the ddPCR assay and the PNA‐LNA clamp method although both indicated that the samples might have mutations. In total, 34 out of 67 PTCL samples (50.7%) had RHOA mutations at the p.Gly17 position. In conclusion, our results suggested that a combination of ddPCR/PNA‐LNA clamp methods and NGS are best method to assist the diagnosis of AITL by detecting RHOA mutations at the p.Gly17 position.

Abstract
A 53-year-old man diagnosed with adult T-cell lymphoma (ATL) was treated with mLSG15 chemotherapy and achieved a first complete remission. Subsequently, a liver tumor emerged that was pathologically diagnosed as ATL (first relapse). A second remission was achieved after local irradiation and four cycles of mogamulizumab treatment. The patient received peripheral blood stem cell transplantation (HSCT) from a one haplotype HLA-mismatched daughter after total body irradiation and the administration of fludarabine as a myeloablative conditioning regimen, followed by post-transplant cyclophosphamide. While subsequent acute graft-versus-host disease (GVHD) was never more than Grade I, severe chronic GVHD (cGVHD) developed in the oral cavity and skin that was resistant to escalated doses of cyclosporine and prednisolone. The patient subsequently had a second relapse of ATL as a subcutaneous mass and eventually died of disease progression. Mogamulizumab is a humanized monoclonal IgG that targets CC chemokine receptor 4 (CCR4) and is a key treatment option for relapsed ATL. It reportedly increases the risk of acute GVHD after HSCT due to the depletion of CCR4-positive regulatory T-cells; however, information on its impact on cGVHD is unavailable. Here, we discuss the potential risks and benefits of mogamulizumab, particularly in a haploidentical donor setting during a HSCT for ATL.

Abstract
BACKGROUND The standard for sentinel lymph node biopsy (SLNB), the dual technique (radiolabelled tracer and blue dye), has several drawbacks. A novel magnetic technique without these drawbacks has been evaluated in a number of clinical trials. It uses a magnetic tracer and a handheld magnetometer to identify and excise sentinel lymph nodes. A systematic review and meta-analysis was performed to assess the performance and utility of the magnetic in comparison to the standard technique. METHODS MEDLINE, PubMed, Embase and the Cochrane online literature databases were used to identify all original articles evaluating the magnetic technique for SLNB published up to April 2016. Studies were included if they were prospectively conducted clinical trials comparing the magnetic with the standard technique for SLNB in patients with breast cancer. RESULTS Seven studies were included. The magnetic technique was non-inferior to the standard technique (z = 3·87, P < 0·001), at a 2 per cent non-inferiority margin. The mean identification rates for the standard and magnetic techniques were 96·8 (range 94·2-99·0) and 97·1 (94·4-98·0) per cent respectively (risk difference (RD) 0·00, 95 per cent c.i. -0·01 to 0·01; P = 0·690). The total lymph node retrieval was significantly higher with the magnetic compared with the standard technique: 2113 (1·9 per patient) versus 2000 (1·8 per patient) (RD 0·05, 0·03 to 0·06; P = 0·003). False-negative rates were 10·9 (range 6-22) per cent for the standard technique and 8·4 (2-22) per cent for the magnetic technique (RD 0·03, 0·00 to 0·06; P = 0·551). The mean discordance rate was 3·9 (range 1·7-6·9) per cent. CONCLUSION The magnetic technique for SLNB is non-inferior to the standard technique, with a high identification rate but with a significantly higher lymph node retrieval rate.

Abstract
BACKGROUND AND PURPOSE Tenascin-C (TnC) is a multi-domain extracellular matrix glycoprotein that is expressed at a high level during embryogenesis but is almost absent during normal postnatal life. This multi-domain complex molecule is reported to associate with both pro-inflammatory and anti-inflammatory signalling cascades. In this study, we examined how TnC modulated intestinal inflammation. EXPERIMENTAL APPROACH TnC pathophysiology was evaluated in cultures of rat intestinal subepithelial myofibroblasts (ISEMF) and intestinal epithelial cells. Wild-type and TnC(-/-) mice were treated with dextran sodium sulfate (DSS) to induce colitis. KEY RESULTS DSS-induced colitis in mice markedly increased TnC in the damaged mucosal areas and up-regulated mRNA for TnC, pro-inflammatory cytokines and growth factors (PDGF-B and TGF-β1). In addition, 2,4,6-trinitrobenzene sulfonic acid-induced colitis and SAMP1/Yit mice, a model of spontaneous Crohn's disease, also exhibited increased mucosal TnC in colon and ilea respectively. PDGF receptor-α (PDGFRα) positive ISEMF were the primary TnC-producing cells in colon tissues. Accordingly, ISEMF collected from the rat colon constitutively expressed both TnC and PDGFRα. PDGF-BB and TGF-β1 up-regulated both TnC mRNA and protein levels in ISEMF. Knock-down of TnC gene increased susceptibility to DSS-induced colitis, compared with TnC(+/+) littermates. TnC(-/-) mice showed marked abrasion of intestinal mucosal barrier and increased inflammatory scores. Moreover, TnC accelerated both trans-well migration and wound healing in epithelial cells. CONCLUSIONS AND IMPLICATIONS The pharmacological profiles of PDGF-BB and TGF-β in colitis tissues and ISEMF suggest that increased TnC production during inflammation contributed to epithelial cell migration, remodelling and protection of intestinal barriers.

Abstract
This report describes a 30-year-old man with a testicular germ cell tumor, which later developed into acute myeloid leukemia (AML) with a common chromosomal abnormality. Testicular germ cell tumors had developed at the age of 26. He was successfully treated with surgery followed by chemotherapy.Four years after the onset of the germ cell tumor, he developed pancytopenia with elevated serum LDH. More than 95% of the bone marrow was occupied by blastic cells. These cells were CD13+, CD34+ but CD45- and MPO-. Amplification of the short arm of chromosome 12 was recognized by fluorescence in situ hybridization using the blastic cells in the bone marrow and the previous testicular tumor specimen. Because testicular germ cell tumor recurrence and other malignant tumors could be ruled out pathologically, he was diagnosed as having AML.Allogeneic stem cell transplantation from a HLA-matched sibling donor was performed after chemotherapy. As of 19 months after the transplantation, recurrence of neither AML nor testicular tumors has been observed. Because the same genetic abnormality was observed in the testicular germ cell tumor and AML in this case, the possibility of AML having a common origin with the testicular germ cell tumor is indicated.

Abstract
Although similar patterns of phenotypic diversification are often observed in phylogenetically independent lineages, differences in the magnitude and direction of phenotypic divergence have been also observed among independent lineages, even when exposed to the same ecological gradients. The stickleback family is a good model with which to explore the ecological and genetic basis of parallel and nonparallel patterns of phenotypic evolution, because there are a variety of populations and species that are locally adapted to divergent environments. Although the patterns of phenotypic divergence as well as the genetic and ecological mechanisms have been well characterized in threespine sticklebacks, Gasterosteus aculeatus, we know little about the patterns of phenotypic diversification in other stickleback lineages. In eastern Hokkaido, Japan, there are three species of ninespine sticklebacks, Pungitius tymensis and the freshwater type and the brackish-water type of the P. pungitius-P. sinensis species complex. They utilize divergent habitats along coast-stream gradients of rivers. Here, we investigated genetic, ecological and phenotypic divergence among three species of Japanese ninespine sticklebacks. Divergence in trophic morphology and salinity tolerance occurred in the direction predicted by the patterns observed in threespine sticklebacks. However, the patterns of divergence in armour plate were different from those previously found in threespine sticklebacks. Furthermore, the genetic basis of plate variation may differ from that in threespine sticklebacks. Because threespine sticklebacks are well-established model for evolutionary research, the sympatric trio of ninespine sticklebacks will be an invaluable resource for ecological and genetic studies on both common and lineage-specific patterns of phenotypic diversification.

Abstract
Retinoic acid related orphan receptor gamma-t (RORγt) is known to be a master regulator of Th17-cell development. In this study, we generated RORγt-overexpressing transgenic (RORγt Tg) mice in which transgene expression was driven by the CD2 promoter, and found that these mice developed polyclonal plasmacytosis and autoantibody production. RORγt Tg mice were generated on a C57BL/6 background, and also were intercrossed with BALB/c mice. BALB/c F1 (BALB/F1) RORγt Tg mice developed massive polyclonal plasma-cytosis, and had shorter life spans. Splenomegaly and infiltration of plasma cells into the lung were observed. Hyperglobulinemia, anti-double-stranded DNA antibodies, anti-erythrocyte antibodies, and anti-platelet antibodies were detected in BALB/F1 RORγt Tg mice. In the present study, polyclonal plasmacytosis in BALB/F1 RORγt Tg mice appeared to be due to the induction of excessive IL-6 production by IL-17. We detected increased numbers of CD11b(+) cells that produced IL-6. We also generatedIL-6-deficient RORγt Tg BALB/F1 background mice, which displayed high levels of serum IL-17, but did not develop severe hyperglobulinemia. Excessive IL-6 production by several cell types, including macrophages, in BALB/F1 RORγt Tg mice, might effect the development of plasma-cytosis. These results suggest that RORγt plays important roles in the development of plasmacytosis and autoantibody production.

Abstract
Multiple myeloma (MM) is a currently incurable neoplasm of terminally differentiated B cells. The translocation and/or overexpression of c-MAF have been observed in human MM. Although c-MAF might function as an oncogene in human MM, there has been no report thus far describing the direct induction of MM by c-MAF overexpression in vivo. In this study, we have generated transgenic (TG) mice that express c-Maf specifically in the B-cell compartment. Aged c-Maf TG mice developed B-cell lymphomas with some clinical features that resembled those of MM, namely, plasma cell expansion and hyperglobulinemia. Quantitative RT-PCR analysis demonstrated that Ccnd2 and Itgb7, which are known target genes of c-Maf, were highly expressed in the lymphoma cells. This novel TG mouse model of the human MM t(14;16)(q32;q23) chromosomal translocation should serve to provide new insight into the role of c-MAF in tumorigenesis.

Abstract
During vertebrate lens development, the anterior, ectoderm-derived lens vesicle cells differentiate into a monolayer of epithelial cells that retain proliferative potential. Subsequently, they exit the cell cycle and give rise to posterior lens fiber cells that form the lens body. In the present study, we demonstrate that the transcription factor GATA-3 is expressed in the posterior lens fiber cells during embryogenesis, and that GATA-3 deficiency impairs lens development. Interestingly, expression of E-cadherin, a premature lens vesicle marker, is abnormally prolonged in the posterior region of Gata3 homozygous mutant lenses. Furthermore, expression of gamma-crystallin, a differentiation marker for fiber cells, is reduced. This suppressed differentiation is accompanied by an abnormal cellular proliferation, as well as with diminished levels of the cell-cycle inhibitors Cdkn1b/p27 and Cdkn1c/p57 and increased Ccnd2/cyclin D2 abundance. Thus, these observations suggest that GATA-3 is essential for lens cells differentiation and proper cell cycle control.

Abstract
Situs inversus totalis represents a complete mirror image anatomy of the normal arrangement of the thoracic and abdominal viscera. This rare condition may pose possible surgical problems due to anatomical abnormality. There were few reports of surgical treatment for lung cancer patient with situs inversus totalis. In this case report, we describe a 74-year-old patient with situs inversus totalis and primary lung cancer who underwent successful left upper lobectomy and systemic lymph node dissection. For this rare condition, detail preoperative evaluation of mirror image anatomy with computed tomography and bronchofiber optic examination was thought to be a key to carry out safe operative procedure.

Abstract
Aspergillosis is a common fungal infection in immunocompromised patients undergoing chemotherapy. The incidence of invasive fungal infection in these patients has increased dramatically in recent years. We report a case of small-bowel infarction caused by Aspergillus in a 48-year-old man who was receiving chemotherapy for acute myeloid leukemia. On day 20 after the start of chemotherapy, right lower abdominal pain and rebound tenderness developed, with a high fever. A contrast-enhanced computed tomography scan showed a semicircular perfusion defect in the ileum. Thus, we performed partial resection of the ileum with primary anastomosis. Macroscopically, the ileum had mucosal ulcerations. Microscopically, there was transmural necrosis with microperforation and Aspergillus invading necrotic tissue and blood vessels. The patient had an uneventful postoperative course and was discharged 14 days after the procedure. Intestinal aspergillosis is rare and associated with high mortality. Thus, it should be considered in the differential diagnosis of neutropenic patients with sudden abdominal pain and fever.

Abstract
Lowering of what we term a driver's Activation State (AS) during monotonous driving conditions may increase the risk of an accident. To develop an in-car environment that allows active driving - "Biofee dforward System" - we have investigated the effects of applying a stimulus of increased inspired oxygen fraction (F<inf>I</inf>O<inf>2</inf>) supply on a driver's AS, using simulated monotonous driving. We used our previously substantiated index of As derived from beat-by-beat blood pressure (BP) response following an electrical stimulus. We have made physiological measurements including BP and found that the increased F<inf>I</inf>O<inf>2</inf>stimulus is effective in enhancing the AS. This finding was also confirmed in terms of the autonomic activity balance as well as the lengthening in time for active, safer, driving.

Abstract
Monotonous automobile operation in our daily life may cause the lowering of what might be termed an activation state of the human body, resulting in an increased risk of an accident. We therefore propose to create a more suitable environment in-car so as to allow active operation of the vehicle, hopefully thus avoiding potentially dangerous situations during driving. In order to develop such an activation method as a final goal, we have firstly focused on the acquisition of physiological variables, including cardiovascular parameters, during presentation to the driver of a monotonous screen image, simulating autonomous travel of constant-speed on a motorway. Subsequently, we investigated the derivation of a driver's activation index. During the screen image presentation, a momentary electrical stimulation of about 1 second duration was involuntarily applied to a subject's shoulder to obtain a physiological response. We have successfully monitored various physiological variables during the image presentation, and results suggest that a peculiar pattern in the beat-by-beat change of blood pressure in response to the involuntary stimulus may be an appropriate, and feasible, index relevant to activation state.

Abstract
We conducted a pilot study to evaluate the feasibility of reduced-intensity cord blood transplantation (RI-CBT) using a non-total body irradiation (TBI) regimen in adult patients with advanced hematologic malignancies. Seventeen patients with a median age of 58 years (range, 38-74) underwent RI-CBT at Tsukuba Memorial Hospital between April 2004 and November 2005. Preparative regimens were fludarabine 30 mg/m(2) for 6 days, and busulfan 4 mg/kg for 2 days. Tacrolimus was used for prophylaxis of graft-vs-host disease (GVHD). Median numbers of infused total nucleated were 2.6 x 10(7)/kg (range, 2.0-3.3). HLA disparity was found in 2/6 antigens (n=16) and 1/6 antigens (n=1). Underlying diseases progressed despite preparative regimens in four patients. Of the remaining 13 patients, nine patients achieved engraftment at a median of day 18 (range, 17-28). Six of the nine patients with engraftment achieved complete donor-type chimerism by day 100. Six patients were alive in remission at median follow-up of 13.1 months (range, 1.0-19.0). This study demonstrated the feasibility of RI-CBT using a non-TBI regimen in adults. When disease progression is controlled by the preparative regimen, RI-CBT carries a clinically significant graft-vs-tumor effect. Further studies are required to identify patients who benefit from this regimen.

Abstract
In vertebrates, sperm development and maturation are directly regulated by gonadal steroid hormone secretion. The relationships among the expression of genes encoding steroidogenic proteins and receptors for gonadotropins, and testicular steroid production have not yet been comprehensively determined in male teleosts. In this study, the changes in levels of mRNAs encoding follicle-stimulating hormone (FSH) receptor, luteinizing hormone (LH) receptor, steroidogenic acute regulatory protein (StAR), cytochrome P450 cholesterol side-chain cleavage, 3beta-hydroxysteroid dehydrogenase/delta5-4-isomerase, cytochrome P450 17alpha-hydroxylase/17,20-lyase, cytochrome P450 11beta-hydroxylase, 11beta-hydroxysteroid dehydrogenase and 20beta-hydroxysteroid dehydrogenase were determined by real-time, quantitative PCR assays and related to changes in serum steroid levels throughout the reproductive cycle in male rainbow trout. Serum 11-ketotestosterone and 17alpha,20beta-dihydroxy-4-pregnen-3-one levels were measured by RIA. Although the pattern of change in the mRNA levels for the enzymes was variable, the increases in steroidogenic enzyme mRNAs started prior to a significant increase of serum steroid levels. The patterns of transcript levels of FSH and LH receptors suggest that changes in StAR and steroidogenic enzyme transcripts are largely mediated by the FSH receptor during early and mid-spermatogenesis and by the LH receptor during late spermatogenesis and spermiation. Levels of StAR (10-fold) and P450 17alpha-hydroxylase/17,20-lyase (sevenfold) transcripts changed with the greatest magnitude and were closely related to the changes in serum steroids, suggesting that changes in StAR and P450 17alpha-hydroxylase/17,20-lyase abundance are likely to be the major influences on overall steroidogenic output during the reproductive cycle in male rainbow trout.

Abstract
PURPOSE To investigate the feasibility of volumetric cine imaging in human cardiac studies by comparing in vivo and in vitro coronary angiography using a 256-detector row computed tomography (CT) without ECG gating. MATERIAL AND METHODS The left and right coronary arteries of two domestic pigs were scanned in vivo and in vitro in cine mode using the 256-detector row CT. The device scanned approximately 100 mm in the cranio-caudal direction with one rotation, with a slice thickness of 0.5 mm. RESULTS The coronary arteries could be observed to the third-degree branches in vitro, but could be visualized clearly only to the proximal portion (first-degree or second-degree branches) in vivo. CONCLUSION Application of cardiac volumetric cine imaging with 256-detector row CT may be a promising means of obtaining diagnostic information and has potential for adoption to human studies.

Abstract
Using the new transgenic mice produced by mating gpt delta with p53 knockout, mutation induction by heavy-ion irradiation and the effect of p53 background on such induction were studied. After the whole body irradiation with 10 Gy of 135 MeV/u carbon-ion beam, the genomic DNA was isolated from the different organs and the lambda DNA was rescued as a phage. Mutations in the transgene on the lambda DNA were determined by the spi(-) selection (deletion assay). The spi(-) mutation was induced by the above irradiation, but enhancement of the mutant frequency by the knockout of p53 gene was found not in the phages recovered from liver but in those from kidney. We are now making an effort to determine the nature of spi(-) mutation to confirm such p53 effect.
