The pharmacokinetics (PK) and pharmacodynamics (PD) of the once-daily, oral ironchelating agent, deferasirox (Exjade, ICL670), have been evaluated further in a Phase I, openlabel, multicenter, dose-escalation study in Japanese patients with myelodysplastic syndromes, aplastic anemia, and other anemias. Deferasirox was initially administered as a single dose(More)
AIMS To evaluate the role of tumour-associated macrophages (TAMs) of the M1 and M2 types in the behaviour of diffuse large B-cell lymphoma (DLBCL). METHODS AND RESULTS Double immunohistochemical staining of HLA-DR/CD68 (M1) or CD163/CD68 (M2) was performed in 101 cases of DLBCL. CD68+ cells represent the total number of TAMs. The average number of(More)
To evaluate roles of tumor-associated macrophages (TAMs) for prognosis of classical Hodgkin lymphoma (CHL). Expression of markers for TAMs, CD68, HLA-DR, CD163, HLA-DR/CD68 (M1), and CD163/CD68 (M2) was immunohistochemically examined in 82 cases with CHL. Positively stained cells were counted and correlation of number of TAMs and patients' survival time was(More)
BACKGROUND Recent studies have shown that cyclooxygenase-2 (COX-2) inhibitors may participate in the proliferation of cancer cells. Because the cadherin-catenin complex is not only a key component of the adherens junction but also has been suggested to regulate cell proliferation, modulation of these molecules may be a mechanism by which COX-2 activity(More)
Change of CD20 expression was examined in cases of diffuse large B-cell lymphoma (DLBCL). CD20 expression after treatment with anti-CD20 antibody (rituximab, Rx) for DLBCL was examined in 23 cases who received serial biopsy by immunohistochemistry (IHC) and flow cytometry (FCM). CD20– by IHC and/or FCM was defined as CD20–. Four cases were CD20– at initial(More)
Classical Hodgkin's disease (HD) is characterized by rare neoplastic Hodgkin and Reed-Sternberg (H-RS) cells within abundant reactive cellular backgrounds. In most cases, H-RS cells originate from the B-cell lineage, but their immunophenotypes are unusual. Here we newly found frequent expression of chemokine receptors CXCR6 and CCR10 and their respective(More)
We describe a patient with Philadelphia chromosome (Ph)-positive chronic myelogenous leukemia (CML) who developed an extramedullary blast crisis in the central nervous system (CNS) and then a subcutaneous tumor of the neck during treatment with imatinib mesylate. Administered 400 mg of imatinib mesylate after the diagnosis of chronic-phase CML, the patient(More)
PURPOSE We previously reported that all-trans retinoic acid (ATRA) inhibited growth in human T-cell leukemia virus type I (HTLV-I)-positive T-cell lines and in fresh cells from patients with adult T cell leukemia (ATL). Here, we confirmed the clinical effects of ATRA in 20 patients with ATL. MATERIALS AND METHODS The 20 patients (n = 20) with a median age(More)
We previously reported that all-trans retinoic acid (ATRA) inhibited growth in HTLV-1-positive T-cell lines and fresh cells from patients with adult T-cell leukemia. Interestingly, ATRA significantly inhibited reverse transcriptase (RT) activity similar to azidothimidine (AZT) in HTLV-1-positive T-cell lines. To clarify whether ATRA has an inhibitory effect(More)
PURPOSE To clarify the change in the fluorodeoxyglucose (FDG) uptake by the bone marrow over time after administration of granulocyte colony-stimulating factor (G-CSF), we evaluated the correlation between the interval from the last day of administration of G-CSF to positron emission tomography/computed tomography (PET/CT) study and spinal bone marrow(More)
