We describe a patient with CML who developed hypercalcemia in his course of blast crisis. A 25-years-old man was diagnosed as CML with priapism in April 1985, and controlled with BHAC-DVP, VMP, busulfan therapy. In December 1987, he readmitted to our hospital with abdominal pain. Investigations at that time showed: white blood cell count 11600/microliters (blast cells 9%); hemoglobin 8.4 g/microliters; platelets 19.0 X 10(4)/microliters; serum calcium 13.2 mg/dl; BUN 44 mg/dl; creatinine 2.7 mg/dl. Treatment with predonine, 6-MP and vincristine was begun. But serum calcium level rose gradually up to 16.5 mg/dl. So we tried middle dose Ara-c therapy, serum calcium decreased to 6.8 mg/dl. At once he was in a chronic phase, but he relapsed and died of heart failure. Necropsy showed extensive leukemic blast-cell infiltration of the bone marrow, liver, spleen, lung, and kidney. The cause of hypercalcemia in our case was suspected of local osteolytic hypercalcemia, because multiple bone destruction was found.

Using the megakaryocytic leukemia cell lines, K-562 and CMK established from a Down's patient with acute megakaryoblastic leukemia, we studied the changes of antigen expression, cytosolic Ca2+ mobilization, thromboxane (TX) A2 formation and gene expression during megakaryocyte differentiation. We found that thrombospondin synthesis and platelet factor (PF)-4 gene expression were specific for mature megakaryoblasts, whereas collagen unresponsiveness and prostaglandin E1-induced Ca2+ mobilization were noted in immature megakaryoblasts alone. This experiment shows that functional and genetic analysis are useful for characterizing the leukemic megakaryoblastic cells. We analyzed the clinical, hematologic and genetic features of 4 patients with M7, and acute megakaryoblastic transformation of CML, MDS and essential thrombocythemia. In two patients, prednisolone and 6-MP were effective in cytoreduction. In 3 patients with increased platelet counts, normal CFU-Meg formation, the megakaryoblasts with platelet production, or the coexistence of immature megakaryoblasts with mature megakaryocytes were observed, thus indicating that some megakaryoblastic leukemia cells still have the capacity of differentiation. One patient had megakaryoblastic cells with PF-4 gene expression. These clinical findings suggest that the megakaryoblastic leukemia could not be characterized as usual leukemia and a more sensitive marker is required to differentiate leukemic megakaryoblasts from normal megakaryoblasts.

Seventy-four patients in the chronic phase of Ph1-positive chronic myelogenous leukemia (CML) have been treated with busulfan or other alkylating agents in a conventional way. During its chronic phase, 24 of these 74 cases had received additional intermittent therapy every 4 to 6 months, consisting of vincristine 2 mg or vindesine 3 mg per week, prednisolone 20-30 mg per day and partly 6 mercaptopurine 50 to 100 mg, combined with allopurinol 200 to 300 mg per day for 2 to 3 weeks. The 50% survival of these patients using the Kaplan-Meier's method was 73.7 months and 5-year survival was 69.6%, against 40.5 months and 14.4%, respectively, in the remaining patients. Nine patients in the blastic or accelerated phase of Ph1-positive CML have been treated with new regimens including MCNU. All cases had been refractory for usual types of induction chemotherapy. The new regimen consisted of MCNU 50-100 mg, combined with vindesine or 6-MP plus allopurinol or prednisolone. Five out of 9 cases attained complete remission and 1 partial remission. The major adverse effect of this regimen was slight liver damage. MCNU could be regarded as an useful agent in the blastic phase as well as in the chronic phase of CML.

Sixteen children with refractory hematological malignancies were treated with a combination of BH.AC, aclacinomycin-A, 6-MP and predonisolone (BH-AC.AMP protocol). They were ALL(6), ANLL(8), CML(1) and NHL(1). The CR ratio was 17% in ALL, 50% in ANLL, and blast crisis of CML was treated successfully but NHL failed in the induction remission. Major complications were vomiting, nausea, gastrointestinal bleeding, hematuria and hemorrhagic cystitis. More than 10 days or 120 mg/m2 administration of aclacinomycin-A was thought to induce more severe side effects.

Forty-six cases with hematological malignancies were treated with vindesine sulfate (VDS); a new semisynthetic vinca alkaloid. Six cases with ALL, 5 cases CML in blastic crisis, 3 Hodgkin's disease (HD) and 4 non-Hodgkin's lymphoma (NHL) were treated with VDS alone. Five out of 6 cases ALL, 2 out of 5 CML in blastic crisis were induced into partial remission with VDS alone. All of 3 HD, and 4 NHL were induced in complete remission (CR) or partial remission (PR). Out of 5 cases AML in CR who received VDS as the maintenance therapy in combination with cyclophosphamide, 6-MP and prednisone, one case relapsed during the treatment, but other four cases maintained CR for 4 to 24 months. One case of APL in relapse, which was treated with VDS and 6-MP, reinduced into CR after one month. Out of 16 cases with malignant lymphoma treated by combination chemotherapy including VDS, eleven cases entered in CR or PR. Out of four cases in which the disease became refractory to vincristine (VCR) or vinblastine (VLB) clinically, two achieved PR. VDS was administered intravenously with 3 mg/body/week. When undesirable effect such as leucocytopenia was observed, the dose was reduced to 2-2.5 mg/body/week or 3 mg/body/2 weeks or month. Neurotoxicity (i.e. Paresthesia 21.7%), alopecia (21.7%), leucocytopenia (19.6%), constipation (10.9%) and fever (6.5%) were main side effects of VDS. The neurotoxicity of VDS, however, seemed far less intensive than VCR.

Transformed chronic myeloid leukemia (CML) has a dismal prognosis, and treatment with a variety of chemotherapeutic agents is extremely disappointing. A novel therapeutic approach was initiated to improve the outcome of this condition. Nine patients, four females and five males, with either acceleration of CML or blast crisis (myeloid), or, in two instances, both, entered this pilot study. Median age was 60 years; seven patients were Philadelphia chromosome positive; two were negative but showed a bcr/abl rearrangement. All patients had a well-defined preceding period of stable chronic phase, for which they received sequentially hydroxyurea (N = 9), interferon (IFN) (N = 3), busulfan (N = 2), melphalan (N = 1), 6-MP (N = 1), or allogeneic BMT (N = 1). Median length of preceding chronic phase to acceleration or blast crisis was 56 months. All patients responded to treatment with a starting dose of IFN (9 Mio U/day), subcutaneously, and hydroxyurea (3 g/day), orally, by reversal to chronic phase. Three of the patients responded repeatedly during their course of disease. Median time for reversal to chronic phase was 4 weeks. Adverse side effects like nausea, vomiting, hair loss, fever, and prolonged cytopenia as seen after chemotherapy were not observed. The duration of chronic phase varied, and lasted, in six instances, more than 5 months, while the Philadelphia chromosome persisted. One additional patient received an unrelated bone marrow transplantation after reaching chronic phase (+24 months). Disease progression occurred 2 months after cessation of treatment. This treatment has proven very promising so far.

94 children with chronic myelocytic leukaemia--CML treated in period 1975-1998 were included in the study. Twenty seven of 60 children were treated with hydroxyurea or busulfan with 6 MP. In 33 children aged 1, 5-17 years IFN (Interferon alfa) was applied at the dose of 3 millions units every second day subcutaneously. Our data showed that IFN alfa could be applied as an alternative treatment in children with CML, who have not a donor for allogenic BMT (bone marrow transplantation).
