BACKGROUND The objectives of this study were to evaluate the effect of the number of infused CD34+ cells on hematopoietic recovery and on the cost in autologous peripheral blood stem cell transplantation (PBSCT). METHODS Sixty-nine patients who received autologous PBSCT (ABSCT) were divided into three groups defined by the number of infused CD34+ cells.(More)
OBJECTIVE B-cell lymphoma-associated hemophagocytic syndrome (B-LAHS) has been increasingly reported in Asia and is regarded as a variant of intravascular lymphomatosis (IVL). Recently CD5 was reported to be expressed in some cases of diffuse large cell lymphoma and IVL. We therefore examined the expression of CD5 on lymphoma cells in B-LAHS and compared(More)
We performed the immunophenotyping of 101 patients with B-cell non-Hodgkin's lymphoma (B-NHL) using two-colour flow cytometry (FCM) and found that lymphoma cells coexpressed at least one kind of T-cell-associated antigen (T-Ag; CD2, CD5, CD7) in 25 patients (24. 8%). Among these three T-Ags, CD5 was the most frequently expressed, in 21 patients (20.8%),(More)
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(More)
Four patients (three males and one female) were diagnosed as myeloid/natural killer (NK) cell precursor acute leukemia in our department. Two patients showed the extramedullary involvement at initial presentation. Leukemic cells expressed CD7, CD33, CD45 and CD56 in all patients. Additionally, CD13, CD34, HLA-DR, cytoplasmic CD3 and myeloperoxidase were(More)
We examined the effect of YM529, a newly developed third-generation bisphosphonate (BP), on the growth of human myeloma cell lines using the trypan blue dye exclusion test and Alamar blue assay. BPs induced inhibition of proliferation in all cell lines dose-dependently, and YM529 had a most potent growth inhibitory effect, followed by incadronate and(More)
Inflammatory pseudotumor is a benign disease entity of unknown etiology and pathogenesis, which mainly affects elderly patients and involves various parts of the body such as the orbit, respiratory tract, gastrointestinal tract, liver, or soft tissue. However, inflammatory pseudotumor of splenic origin has been rarely reported [1]. Here, we report a patient(More)
The feasibility and efficacy of a combination of thalidomide, incadronate, and dexamethasone (TID) were studied in 12 patients with relapsed or refractory multiple myeloma. The protocol, consisting of 300 mg/day of thalidomide administered orally, intravenous incadronate (10 mg/day) administered weekly, and 12 mg/day dexamethasone for 4 days, was repeated(More)
A 54-year-old man diagnosed with IgD myeloma (stage IIIA) in complete remission (CR) received peripheral blood stem cell transplantation (PBSCT) twice with an interval of 4 months using high-dose melphalan 200mg/m2. However 9 months after the second PBSCT, he was readmitted because of lumbago, lower left hemiparesis, speech disturbance and left facial nerve(More)
