Four patients affected by chronic myeloid leukemia who developed osteolytic lesions in the course of the disease are described. According to the literature, the appearance of these alterations seems to signify an unfavorable prognosis, since they occur slightly before or even at the same time as the blastic transformation of the disease. However, in one case bone biopsy showed a metastasis of a solid tumor, emphasizing the importance of this procedure in order to give a more precise clinical evaluation, both diagnostic and therapeutic.

Q fever is caused by Coxiella burnetii, a strictly intracellular bacterium that lives within the phagolysosome of infected cells. We report here five cases of Q fever in patients with cancer. Three of them had a solid tumor, one had a B cell lymphoma, and one had chronic myeloid leukemia. One patient had acute Q fever, and the four others had chronic Q fever endocarditis. Two patients with endocarditis had no previous history of valvulopathy. C. burnetii was isolated from the valves of two patients. One of the patients with endocarditis died. Patients with cancer who have unexplained fever and live in areas in which C. burnetii is endemic should undergo serological testing for infection with this microorganism.

Trisomy 21 as an acquired clonal chromosome change has been described in 642 of the 10,625 human neoplasms with chromosome aberrations known from the cytogenetic literature. A total of 590 of the 642 cases (92%) are hematologic disorders and malignant lymphomas. The incidence of trisomy 21 is similar (4.1%-6.7%) in acute myeloid leukemia (AML), chronic myeloid leukemia, myeloproliferative disorders, myelodysplastic syndromes, chronic lymphoproliferative disorders, and malignant lymphomas; it is substantially higher (14.8%) in acute lymphocytic leukemia (ALL). In most cases, the extra chromosome 21 is present together with other numerical and/or structural changes. Acquired trisomy 21 is the only karyotypic abnormality in only 0.4%. Trisomy 21 has never been reported as the sole anomaly in a solid tumor. The cytogenetic literature contains information on 62 patients with constitutional trisomy 21 and a malignant disorder in which the tumor cells have been analyzed by banding techniques. Thirty-four of the 62 patients had AML, 16 had ALL, and 2 had acute undifferentiated leukemia. The 52 leukemic Down syndrome (DS) cases account for 1.4% of the total acute leukemias, an overrepresentation that parallels the generally increased risk of leukemia development in DS. Sixty-three percent of the ALL patients and 79% of those with AML had additional changes superimposed on constitutional trisomy 21. These included several of the characteristic primary leukemia-associated aberrations: 5q-, 7q-, +8, and t(8;21) in AML, and t(1;19), t(4;11), 6q-, and 14q + in ALL. Thus, it seems that the pattern of acquired karyotypic changes is similar in patients with DS and in individuals with a normal constitutional karyotype.

Monoclonal antibodies of IgG1 type immunoglobulin, directed against soluble CML antigen isolated from the reactive CML peripheral myelocytes, were reported. These MAbs were further investigated for their reactivity by 125I-Protein-A binding assays, indirect immunofluorescence tests, cytotoxicity, SDS-PAGE, immunoelectrophoresis, and by immunodiffusion suggesting that they recognized antigens specific mostly to undifferentiated cells. These were tested against various leukemic peripheral blood leukocytes, bone marrow cells, established cell lines of various origin, and with many solid tumor cells and demonstrated specific reactivity with CML myelocytes alone and cell lines of myeloid origin. Indirect immunoperoxidase staining of single cell preparation revealed peroxidase localization in most promyelocytes and in few mature myelocytes from CML PBL/BM cells, thus helping in identifying the exact type (morphology) involved in reacting specifically with these MAbs.

Cancer chemotherapy combined with calcium-channel blockers was administered to seventeen evaluable patients with hematologic malignancy and solid tumor who became resistant to standard chemotherapies between November 1981 and June 1986 in Saitama Cancer Center. Nicardipine and diltiazem were used as the calcium-channel blockers, which were given orally or intravenously. Adriamycin and/or vinca alkaloids were mainly used as a cancer chemotherapy. Partial remission was attained in 3 of 6 patients with malignant lymphoma. Remission was attained in 2 of 7 patients with acute leukemia including acute transformation of chronic myelogenous leukemia (CML/BC), one complete remission with acute lymphocytic leukemia and one cytoreductive effect with CML/BC. One partial response and one minor response were obtained among 4 patients with solid tumor. The remission of these responders was of short duration. The most serious side effect caused by calcium-channel blockers was hypotension, which was dose-limiting and induced oliguria in 6 of 23 courses. In conclusion, the clinical impression obtained with regard to the effectiveness against chemotherapy-resistant malignancies of cancer chemotherapy combined with calcium-channel blockers was not good even though the overall remission rate was 41%.

Cyclic cytidine 3':5'-monophosphate (cyclic CMP), cyclic guanosine 3':5'-monophosphate (cyclic GMP), and cyclic adenosine 3':5'-monophosphate (cyclic AMP) contents of leukocytes and urines of leukemic patients have been investigated. We have studied four types of leukemia: acute myeloblastic leukemia; chronic myelocytic leukemia; acute lymphoblastic leukemia; and chronic lymphocytic leukemia. As controls, the cyclic nucleotide content of leukocytes and urines of healthy volunteers and patients with solid tumors selected for their normal hemogram has been determined. It has also been measured in phytohemagglutinin-stimulated lymphocytes. Our data show that: (a) the concentration of cyclic CMP is always lower than that of cyclic GMP or cyclic AMP; (b) in urines, the concentrations of the three nucleotides are higher in patients than in healthy volunteers, the greatest differences being observed between the cyclic CMP concentrations of acute leukemia patients and controls; and (c) in white blood cells, cyclic AMP concentration is lower in leukemic than in normal cells. The cyclic GMP concentration is the same everywhere except in monoblastic cells and leukocytes from solid tumor patients. High cyclic CMP levels are associated only with acute leukemia, whether myeloblastic, monoblastic, or lymphoblastic, a fact which suggests that cyclic CMP could be a biochemical marker of hematopoietic stem cell malignancy.

A new abnormality of chromosome 17, distinct from i(17q), was observed in bone marrow cells of two patients with CML during a blast crisis. The marker was identified as a translocation of the short arm of chromosome 5 onto the long arm of chromosome 17, i.e., t(5p; 17q). In one case, the marker was clearly dicentric. The clinical history of these two patients showed some similarities. A slightly different marker has previously been observed in a cell line derived from a solid tumor.

Granulocytic sarcoma (GS) is a solid tumor of extramedullary localization constituted by immature precursors from the granulocytic series. GS may be diagnosed in different malignant blood diseases involving the granulocytic series, acute non lymphoblastic leukemia (ANLL) being the most frequent, followed by myelodysplastic syndromes (MDS) and chronic myeloproliferative syndromes, specially chronic myeloid leukemia (CML) in blastic crisis. Although the diagnosis of GS is suspected with conventional cytologic and anatomopathologic studies, histochemical staining and immunohistochemical techniques are often required for definitive diagnosis. Five cases (4 males, 1 female; age range 22-77 years) diagnosed with GS in one center over a period of nine years (1984-1993) are described. The GS were located in the lymph nodes, the jaw, paravertebral region, gallbladder and retroperitoneum, respectively. Two patients had refractory anemia with excess of blasts (RAEB). Three patients had ANLL; in one GS constituted the form of relapse, in another GS presented at the time of diagnosis and in the remaining patient GS preceded the diagnosis of ANLL. All the patients died from 2 to 8 months after diagnosis of GS with no response to treatment being observed. Immunohistochemical study of the tumor was performed in 4 patients, being positive for lysozyme and the monocytic MAC-387 monoclonal antibody. Immunocytochemical study of the tumor blasts was carried out with positivity for CD15 being observed. Although uncommon, GS should be suspected in patients with ANLL or MDS with tumors of any localization and at any time during its evolution. Immunocytochemical and immunohistochemical studies are of great value to differentiate GS from other tumors, particularly anaplastic non Hodgkin's lymphomas.

The therapeutic effects of Factor XIII (F XIII) concentrate against drug-induced hemorrhagic cystitis (HC) was investigated. HC occurred in 4 children with malignant disease during anti-cancer chemotherapy. Two (CML and T-ALL) of 4 patients developed HC after the administration of high dose cyclophosphamide as conditioning for allo bone marrow transplantation or peripheral blood stem cell autografts, and the other 2 patients (rhabdomyosarcoma, Wilm's tumor) developed HC after the administration of ifosfamide for relapse. When F XIII concentrate at a dose of 20 to 230 U/kg was administrated immediately after the onset of HC, the symptoms, i.e., bladder irritability and macrohematuria disappeared within a few days. The F XIII serum levels of those patients were low (27-57%), and the levels increased (63-230%) after administration of F XIII concentrate. The two patients with relapsed solid tumor showed no symptoms of HC during subsequent ifosfamide treatment when F XIII concentrate was administrated to maintain a normal F XIII range. These results suggest that the administration of F XIII concentrate may be useful for the prophylaxis and treatment of drug-induced HC in patients with a low F XIII level.
