Brentuximab vedotin is an antibody-drug conjugate that selectively delivers the antimicrotubule agent monomethyl auristatin E into CD30-expressing cells. To assess its safety, pharmacokinetics, and efficacy in Japanese patients with refractory or relapsed CD30-positive Hodgkin's lymphoma or systemic anaplastic large-cell lymphoma, we carried out a phase(More)
EZH2, a core component of polycomb repressive complex 2 (PRC2), plays a role in transcriptional repression through histone H3 Lys-27 trimethylation and is involved in various biological processes, including hematopoiesis. It is well known that 3-deazaneplanocin A (DZNep), an inhibitor of S-adenosylmethionine-dependent methyltransferase that targets the(More)
Although initial rituximab-containing chemotherapies achieve high response rates, indolent B-cell non-Hodgkin lymphoma (B-NHL), such as follicular lymphoma (FL), is still incurable. Therefore, new effective agents with novel mechanisms are anticipated. In this multicentre phase II study, patients with relapsed/refractory indolent B-NHL and mantle cell(More)
Aplastic anemia is characterized by a reduced hematopoietic stem cell number. Although GATA-2 expression was reported to be decreased in CD34-positive cells in aplastic anemia, many questions remain regarding the intrinsic characteristics of hematopoietic stem cells in this disease. In this study, we identified HOXB4 as a downstream target of GATA-2 based(More)
Hepcidin is the principal iron regulatory hormone, controlling the systemic absorption and remobilization of iron from intracellular stores. The expression of the hepcidin gene, HAMP, is increased in patients with anemia of chronic disease. Previously, the synthetic compound K7174 was identified through chemical screening as a novel inhibitor of the(More)
Heterozygous GATA-2 germline mutations are associated with overlapping clinical manifestations termed GATA-2 deficiency, characterized by immunodeficiency and predisposition to myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). However, there is considerable clinical heterogeneity among patients, and the molecular basis for the evolution of(More)
BACH2, a B cell-specific transcriptional repressor, plays a significant role in B cell maturation. Despite a number of previous studies, the clinicopathological significance of BACH2 expression in diffuse large B cell lymphoma (DLBCL) remains to be established. The present study was performed to validate the significance of BACH2 expression as a predictor(More)
BACKGROUND Primary adrenal lymphoma (PAL) is an extremely rare subtype of extranodal non-Hodgkin's lymphoma. Some researchers have reported some of the characteristics of PAL and its association with poor prognosis; however, the clinicopathological features of PAL remain to be elucidated. METHODS From 2008 to 2011 we experienced seven cases of PAL in our(More)
BACKGROUND Follicular lymphomas of the ocular adnexa are very rare in Japan, with only two reported cases. CASE A 44-year-old woman visited our clinic for treatment of ocular adnexal tumors in both eyes. FINDINGS Histologic examination showed that the neoplastic lesions consisted of atypical lymphoid cells, and the tentative diagnosis was malignant(More)
In the FIRST trial (MM-020), lenalidomide plus low-dose dexamethasone (Rd) reduced the risk of disease progression or death compared with combination melphalan-prednisone-thalidomide. As the FIRST trial did not include any Japanese patients, the efficacy and safety of continuous treatment with Rd was evaluated in 26 Japanese patients with newly diagnosed(More)
