We report a case of primary cardiac lymphoma (PCL) occurring in a 76-year-old man during maintenance hemodialysis. Chest computed tomography (CT) revealed a tumor with pericardial effusion in the left ventricular posterior wall. Cytological examination of the pericardial fluid revealed monotonous lymphoid cells positive for B-cell markers, and clonal(More)
The CC-chemokine receptor 4 (CCR4) is expressed in almost ATLL cells. Thus, anti-CCR4 antibodies can be used as a treatment strategy for ATLL. Mogamulizumab (MOG), which is a defucosylated anti-CCR4 monoclonal antibody, showed good results even in patients with recurrent ATLL in phase I or II studies. We treated 8 elderly patients with ATL who were(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)
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. The 20 patients (n = 20) with a median age of 56 (range 35–73) years who(More)
Elderly patients with secondary acute myeloid leukemia (AML) following myelodysplastic syndrome (MDS) are often medically unfit for or resistant to chemotherapy, and their prognosis is dismal. In the present paper, we reported a case of secondary leukemia following MDS in an 80-year-old male patient who was deemed unfit for chemotherapy owing to his old age(More)
The involvement of adult T-cell leukemia (ATL) cells in organs such as the skin and lymph nodes is observed in about 50% of cases of ATL. Epstein-Barr virus (EBV) infection has often been observed in the clinical course of ATL. In this study, we established two B-cell lines from peripheral blood of patients with ATL. EBV DNA, proviral DNA for HTLV-1 and Tax(More)
We previously reported mRNA expression of glutathione S-transferases theta (GSTT)-1, wild type (623 bp) and mutant (500 bp), in patients with myelodysplastic syndrome (MDS). The deletion of 123 bp creates a sequence that is homologous to the mammalian target of rapamycin (mTOR). To analyze the function of mutant GSTT-1 gene, stable transformants for the(More)
