We examined human T-lymphotropic virus type I (HTLV-I) infection among patients with myelodysplastic syndrome (MDS), refractory anemia with excess of blasts (RAEB)/RAEB in transformation (RAEBt) and acute myelogenous leukemia (AML). The study population consisted of 151 patients: 46 with MDS RAEB/RAEBt and 105 with AML (M1, n = 15; M2, n = 39; M3, n = 18;(More)
Granulocyte-colony stimulating factor (G-CSF), a hematopoietic growth factor, is widely used to accelerate recovery from neutropenia after severe chemotherapy, both decreasing the risk of infection and mobilizing peripheral blood stem cells. Adverse effects occur with G-CSF use in approximately 30% of cases, comprised predominantly of bone pain, headache,(More)
The present study examines the clinical significance of serum neuron-specific enolase (NSE) in patients with adult T cell-leukemia (ATL). Serum NSE values were measured using a radioimmunoassay in 35 patients (acute type, n = 15; lymphoma type, n = 10; chronic type, n = 10) and in 7 controls carrying T lymphotropic virus type-1 (HTLV-1). Serum NSE values(More)
The spleen is an immunological organ commonly involved in both hematological and nonhematological diseases. Pathological rupture of the spleen has been described in a variety of diseases affecting the spleen. Infections have been cited in most cases involving splenic rupture, but are rare in hematological malignancies despite frequent involvement of the(More)
Previous studies have suggested that higher anti-human T-lymphotropic virus 1 (HTLV-1) antibody titer and lower anti-HTLV-1 Tax antibody reactivity are risk factors for adult T-cell leukemia/lymphoma. In the present study, we analyzed the relationships between these factors and clarified their significance. Forty-five carriers were examined for anti-HTLV-1(More)
Adult T cell leukemia (ATL) is one of the most refractory malignant hematological diseases. Our previous studies demonstrated HTLV-1Tax protein involvement in clinical manifestation of the aggressive type of ATL and suggested the potential application of agents to inhibit Tax expression for ATL treatment. In the present study, we first examined Tax(More)
Adult T cell leukemia/lymphoma (ATL) is an aggressive peripheral T cell neoplasm with very poor prognosis. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has been reported as a curative treatment modality for ATL. However, there are no reports comparing chemotherapy alone with allo-HSCT in ATL. In this report, we retrospectively analyzed(More)
A 61-year-old man with progressive adult T-cell leukemia/lymphoma (ATLL) successfully received reduced-intensity conditioning stem cell transplantation (RIST) without T-cell depletion (TCD) from his HLA-incompatible son, who had negative results for human T-lymphotropic virus type 1 (HTLV-1) (1-locus, 1-allele mismatch in the graft-versus-host [GVH](More)
