Peripheral blood lymphocytes from 11 patients with chronic lymphocytic leukemia were stimulated by Epstein-Barr virus (EBV), lipopolysaccharide from Escherichia (LPS), and phytohemagglutinin (PHA). Chromosome analysis with the Q-banding technique after 5 days incubation revealed an extra chromosome 12 in 5 of the patients and a translocation between(More)
Fifty-five patients with a clonal expansion of B lymphocytes in the peripheral blood were studied. According to the Kiel classification, 22 patients had chronic lymphocytic leukemia (CLL), 29 had immunocytoma (IC), two had prolymphocytic leukemia, and one had centrocytic lymphoma; one was not subclassified. Cytogenetic studies after B cell mitogen(More)
The response to treatment with low-dose ara-C was studied in 102 consecutive patients; 79 with myelodysplastic syndrome (MDS) and 23 with acute myelogenous leukaemia (AML) following MDS. The aim was to find variables that could predict the response to treatment. All patients had clinical symptoms related to cytopenia. Peripheral blood values, bone marrow(More)
63 evaluable patients with myelodysplastic syndromes (MDS) and 15 with acute myelogenous leukemia (AML) were randomized between low-dose ara-C (arm A) and low dose ara-C in combination with 13-cis-retinoic acid (13-CRA) and 1 alpha-hydroxy-vitamin D3 (1 alpha D3) (arm B). 69 patients were evaluable and 18 (26.1%) responded to therapy. The addition of 13-CRA(More)
Two cell lines with different in vitro growth patterns were established from the pleural fluid of a patient with malignant epithelial pleural mesothelioma. The cell line established in RPMI 1640 supplemented with human AB serum had an epithelial morphology, while the cell line established in fetal calf serum-supplemented medium had a fibroblast-like(More)
Chromosomal aberrations occur in both B-CLL and T-CLL. The polyclonal B-cell mitogens, in particular Epstein-Barr virus and lipopolysaccharide from E. coli, have been used successfully to reveal chromosomal abnormalities in 40-60% of patients with B-CLL, while T-cell mitogens have shown chromosomal aberrations in T-CLL. The most common clonal chromosomal(More)
Leukaemic blood lymphocytes from a patient in the terminal stage of chronic lymphocytic leukaemia (CLL) according to the Kiel classification were stimulated by lipopolysaccharide from Escherichia coli. During progression to blast transformation, stimulated cells lost receptors for mouse erythrocytes (MRBC), accumulated intracellular Ig (cIg), and expressed(More)
62 evaluable patients with myelodysplastic syndromes (MDS) or acute leukemia were treated with different combinations of low dose ara-C, alpha-interferon (IFN), 1 alpha-hydroxyvitamin D3 (vit D3) and retinoic acid. The aim was to study the efficacy and toxicity of each combination. The overall rate was 44%. Of these, 50% responded favorably to the(More)
