Background Leptomeningeal metastasis (LM) occurs in 4–15% of patients with solid tumors. Although the clinical outcomes in cancer patients have been improving recently, no standard treatment for LM has been established as yet. The purpose of this study was to identify the prognostic factors in patients with solid tumors with cytologically proven LM. Methods(More)
Linezolid (LZD) is the first oxazolidinone antibiotic that is effective against drug-resistant gram-positive organisms. Hematological toxicities such as thrombocytopenia, anemia, and leukocytopenia are common in LZD therapy. However, LZD-induced pure red cell aplasia (PRCA) is very rare. A 56-year-old man with myelodysplastic syndrome underwent allogeneic(More)
Biphenotypic acute leukemia (BAL) is a rare entity that comprises 0.5-3% of all acute leukemias and probably arises from multipotent progenitor cells. The optimal approach for BAL therapy is unknown. Thus, it is important to elucidate the origin of the neoplastic cells for determination of the appropriate therapy. We report the case of a 41-year-old man(More)
To evaluate whether rescue with cord blood transplantation (CBT) could improve the poor survival after graft failure (GF), we surveyed the data of 80 adult patients (median age, 51 years) who received CBT within 3 months of GF (primary 64, secondary 16), with fludarabine-based reduced-intensity regimens with or without melphalan, busulfan, cyclophosphamide,(More)
To evaluate the prognostic impact of monosomal karyotype on post-remission outcome in acute myeloid leukemia, we retrospectively analyzed 2,099 patients who had achieved complete remission. Monosomal karyotype was noted in 73 patients (4%). Of these, the probability of overall survival from first complete remission was 14% at four years, which was(More)
UNLABELLED Randomized trials of acute myeloid leukemia (AML) in first complete remission (CR1) showed that autologous hematopoietic cell transplantation (auto-HCT) improves relapse-free survival (RFS) but not overall survival (OS), compared with chemotherapy. Using a database of 2518 adult patients with AML in CR1, we conducted a 5-month landmark analysis(More)
Bortezomib blocks the activation of nuclear factor-kappaB-mediated pro-inflammatory cytokines, however, systemic inflammatory symptoms following bortezomib administration have been reported, although their mechanisms remain elusive. Serum samples were obtained from five patients, who participated in a phase I/II study of Japanese patients with relapsed or(More)
Fibronectin (FN) plays important roles in the proliferation, differentiation, and maintenance of megakaryocytic-lineage cells through FN receptors. However, substantial role of FN receptors and their functional assignment in proplatelet-like formation (PPF) of megakaryocytes are not yet fully understood. Herein, we investigated the effects of FN receptors(More)
CMV disease is a serious complication after allogeneic hematopoietic SCT (Allo-HSCT) in addition to GVHD. CMV disease can involve many organs and the gastrointestinal tract is a common site. There are several reports on small intestinal endoscopic findings of GVHD detected by capsule endoscopy, but only limited information has been published regarding(More)
Adjuvant chemotherapy by S-1 following gastrectomy is considered standard treatment in Japan. Analysis of follow-up data have proved the efficacy of S-1 administration, and that hematological adverse events were relatively rare. Pyrimidine anti-metabolites, including S-1, have shown relatively lower risks for secondary hematological malignancies in(More)
