From January 1988 until December 1990, 99 previously untreated patients with multiple myeloma (MM) were enrolled in a randomized prospective study comparing two combination chemotherapies with and without MCNU as induction therapy for MM; 49 patients with vindesine, melphalan and prednisolone (VMP therapy) versus 50 patients with MCNU, vindesine, melphalan(More)
Among 1119 Japanese patients with symptomatic multiple myeloma diagnosed between 1965 and 1981, 38 (3.4%) survived more than 10 years. Younger age, low tumour mass (absence of severe anaemia, hypercalcaemia, renal failure, and multiple bone lesions), low plasma cell percentage in bone marrow, mature and intermediate myeloma according to Greipp's criteria,(More)
Gene targeting studies in mice have shown that the lack of Ikaros activity leads to T-cell hyperproliferation and T-cell neoplasia, establishing the Ikaros gene as a tumor suppressor gene in mice. This prompted us to investigate whether mutations in Ikaros play a role in human hematological malignancies. Reverse transcription-PCR was used to determine the(More)
We report a case of B-cell chronic lymphocytic leukemia (B-CLL) in which trisomy 12 and t(14;18)(q32;q21) were simultaneously detected in the same leukemic clone. Southern blot analysis showed that the BCL2/IgJH rearrangement occurred at the major breakpoint region in the hot spot of the BCL2 gene. Double color fluorescence in situ hybridization analysis(More)
During the past 6 years we have experienced a total of 6 cases of malignant lymphomas, which originated primarily in the central nervous system. The most reliable diagnostic criteria will be a "perivascular cuffing" by silver impregnation with further spreading of tumor cells to the periphery, a "starry-sky" appearance consisting of numerous histiocytes(More)
Fourteen patients with multiple myeloma received aclarubicin (ACR) intravenous drip infusion at a dose of 15-25 mg/m2/day for 7 days every 3 weeks. Nine of the patients achieved more than a 25% reduction in M-protein. In two of the nine the reduction was more than 50% and the duration of their responses was 2.0 and 2.8 months, respectively. In the nine(More)
We report a case of hyperimmunoglobulin E syndrome (HIE) complicated by neutrophil deficiency which was successfully treated with oral administration of disodium cromoglycate. A 48-year-old Japanese man with HIE developed Streptococcus pneumoniae meningitis. Laboratory tests after the meningitis revealed persistent neutropenia (300-800/mm3) and defects of(More)
