    Notes: Summary Our purpose was to evaluate the ability of re-combinant human granulocyte colony-stimulating factor (r-metHuG-CSF) as an adjunct to induction chemo-therapy of acute lymphoblastic leukemia (ALL) to ameliorate chemotherapy-induced neutropenia and thus allow patients to receive full doses of chemotherapy on time. Sixteen consecutive patients with adult ALL (13 de novo, three relapsed) were treated with induction chemo-therapy according to the BMFT protocol and received in addition r-metHuG-CSF (200μg/m2/day). Patients who were treated with the same induction chemotherapy but without G-CSF between 1982 and 1990 served as controls. Fifteen of the 16 patients achieved complete hematological remission. One patient died because of fungal septicemia. Compared with historical controls, G-CSF-treated patients had a significantly faster neutrophil recovery in phase I, resulting in neutrophil counts 〉 1000/μl at day 17 vs day 26 (in median) in controls. In phase II, the onset of severe leukocytopenia (〈 1500/μl) was significantly (p = 0.01) delayed and the degree of leukocytopenia less pronounced (mean nadir 3300/μl) in G-CSF-treated patients compared with controls (1880/μl). The number of days of febrile neutropenia was not different in phase I. In phase II it was lower in study patients (0 vs 1.1 days), but the difference did not reach statistical significance (p = 0.09). Full doses of chemo-therapy could be given on time to 11/13 (85%) G-CSF pa-tients but to only 7/30 (23%) controls. These data indicate that (a) G-CSF can be given along with chemotherapy in induction treatment of ALL without compromising efficacy; (b) the duration of neutropenia in phase I is markedly shortened and the degree of leukocytopenia in phase II ameliorated; (c) these beneficial effects allow patients to receive full doses of chemotherapy on time.

    Notes: Summary We describe a 68-year-old patient who developed granulocytic sarcoma of the prostate 9 years after complete remission following successful treatment of acute myelogenous leukemia (FAB, M2). PCR analysis of bone marrow samples in first remission and at the time of relapse detected an AML1/ETO rearrangement typical for AMLs with t (8; 21). The CD 56 antigen was not expressed on the leukemic cells. Systemic chemotherapy led to a short-lasting regression of the tumor, but the patient subsequently developed overt bone marrow relapse and died during chemotherapy. While granulocytic sarcoma as a primary manifestation of AML is well known, as the first manifestation of relapse it appears to be very uncommon.

    Notes: Abstract  Twenty-two patients with refractory or relapsed AML were treated with FLAG [25 mg/m2 fludarabine daily (days 1–5), 2 g/m2 daily Ara-C (days 1–5) and 400 μg/m2 daily G-CSF (day -1 till the absolute neutrophil count was 〉500/μl)]. Median age was 46 years (range 24–63). Eight patients had leukemia which was primarily refractory to conventional regimens, six were in first, seven were in second, and one was in third relapse. Overall, 11 of 22 (50%) patients achieved complete remission (CR), three had a partial response (PR), and seven did not respond (NR). One patient died of an early cerebral hemorrhage. The median remission duration from achievement of CR after FLAG was 9.9 months and median survival was 13.0 months. One patient is alive in CR at 31.9 months. Hematological toxicity of the regimen was severe. The median time to neutrophil recovery (ANC 〉500/μl) was 21 days (range 18–33). A median of seven red cell units (range 0–22) and of six platelet concentrate units (range 3–28) had to be given. Median duration of febrile neutropenia was 2 days (range 0–20 days) and patients were on i.v. antibiotics for a median of 16 days (range 0–51). There was no death from infection. Nonhematological toxicity was remarkably low, with almost no neurotoxicity and no major hepatotoxicity. In conclusion, FLAG seems to be an efficient and well tolerated regimen. It may be particularly useful for patients who have a sibling or unrelated donor for subsequent allogeneic bone marrow transplantation.

    Notes: Abstract  We report a case of low-molecular-weight heparin (LMWH)-induced skin necrosis in a patient with chronic lymphatic leukemia. The patient had heparin-PF4 antibodies and the heparin-induced platelet activation (HIPA) test was positive, but platelet counts remained normal. Analysis of seven cases of LMWH-induced skin necrosis revealed that this complication occurred mostly in patients previously exposed to heparin, and that severe problems such as thrombocytopenia or thromboembolic complications were rare. This is in contrast to skin necrosis induced by unfractionated heparin (UFH), where a substantially higher number of patients suffered from thrombocytopenia and thromboembolism. In addition, most patients with UFH-induced skin necrosis were not pretreated with heparin. Therefore, it is possible that LMWH is less immunogenic than UFH and requires repeated exposure for induction of skin necrosis.

    Notes: Abstract  Seven patients with macroglobulinemia (six previously untreated, one with minimal pretreatment) were treated with fludarabine (25 mg/m2/day for 5 days, repeated every 4 weeks). The median age was 58 years. The time from diagnosis to treatment with fludarabine was 4.5 months to 175 months (median 32.6 months). The patients received six (n=5), five (n=1), and three (n=1) courses of fludarabine. One patient showed only a slight decrease of immunoglobulin (Ig) M (from 5750 mg/dl to 4700 mg/dl) and no improvement of anemia. Therefore, treatment was stopped after three cycles. In the other six patients, a marked reduction of IgM levels (from 6140 mg/dl to 1220 mg/dl median), a normalization of hemoglobin (from 10.8 g/dl to 12.3 g/dl median), a reduction of lymphocyte count (from 1992/μl to 652/μl median), and a reduction of β2 microglobulin (from 2.3 mg/l to 1.8 mg/l median) were achieved. A 50% IgM reduction was achieved 5.4 months (median) after the beginning of therapy, and the maximum response was observed 17.3 months (median) after the end of treatment. The responses were sustained without further therapy in six patients for 20.8–55.2 months. In one patient, disease progression was observed 12.5 months after the end of therapy. Fludarabine therapy was well tolerated with few side effects. In three patients, febrile episodes occurred. No opportunistic infections were recorded. We conclude that fludarabine is an effective treatment in previously untreated or in minimally pretreated patients with Waldenström's macroglobulinemia.

    Notes: Abstract  Multiple myeloma with IgG-lambda monoclonal gammopathy and severe renal impairment with light-chain deposit disease was diagnosed in a 51-year-old man. Following conventional therapy with VAD (vincristine, adriamycin, dexamethasone) a partial remission was achieved. Peripheral blood stem cells (PBSC) were then collected following mobilization with cyclophosphamide and recombinant human granulocyte colony-stimulating factor and enriched for CD34-positive cells by immunoaffinity column. Fourteen months after diagnosis high-dose melphalan was given, followed by infusion of CD34-positive PBSC. Aside from mild oral mucositis and trigonitis, high-dose therapy was tolerated well. After he underwent PBSC transplantation his renal function improved, and the patient has been in in continuous complete remission for 1 year. Thus, high-dose chemotherapy can be safely administered to patients with multiple myeloma and severe renal impairment. Our findings confirm previous reports summarized in the current presentation.

    Notes: Abstract  Idiopathic myelofibrosis (IMF) is a chronic myeloproliferative disorder characterized by fibrosis of the bone marrow, varying degrees of extramedullary hematopoiesis, splenomegaly, anemia, and a leukoerythroblastic peripheral blood smear. Bone marrow fibrosis develops as a secondary phenomenon and is caused by increased intramedullary activity of mitogens such as platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), basic fibroblast growth factor (bFGF), epidermal growth factor (EGF), and calmodulin. Because of the variable clinical course of IMF, attempts have been made to define prognostic parameters that can be helpful in detecting patients with a shortened life expectancy. The most important adverse prognostic parameters that have been reported are hemoglobin concentration, age, leukocyte count, number of thrombocytes, and cytogenetic abnormalities. However, no standardized prognostic score for IMF has yet been established. Therapeutic strategies in IMF remain predominantly supportive. The most common are blood transfusions, androgens, and cytoreductive agents such as hydroxyurea. Bone marrow transplantation is increasingly being taken into consideration, but it still has to be regarded as an experimental approach. Interferon-α (IFN-α) has shown promising results in early hyperproliferative stages of IMF but has no or only very little effect in more advanced stages of the disease. Whether IFN-α is able to postpone marrow fibrosis if administered in early disease stages remains to be determined in future clinical trials.

    Notes: Abstract  A total of 168 patients with de novo AML were retreated with chemotherapy at relapse following first CR; 66 patients (39%) achieved a second complete remission (CR). The probability of achieving a second CR was highly dependent on the duration of the first remission. Patients who received no or conventional postremission chemotherapy after second CR had a median remission duration of 7.5 months, and the probability of remaining in remission at 3 years was 24%. Patients with a first CR of more than 12 months had a median second remission duration of 18 months. The probability of a second CCR was 35% at 3 years and 24% at 5 years, whereas none of the patients with a first CR of less than 12 months was in remission at 3 years. Only a poor correlation (p=0.31) was found when the durations of the first and second CR were compared in patients with a second relapse. Patients with long-lasting remissions and long-term survivors after second CR are characterized by a first CR duration of 〉12 months and favorable or normal cytogenetics. The type of salvage treatment seems to be less important for achievment of long-term remission, but it is probably important to administer consolidation chemotherapy after second CR. Other so-far ill-defined factors may be responsible for the supression of the leukemic clone in patients with long-lasting remissions following chemotherapy for relapse after second CR.

    Notes: Abstract  A 68-year-old woman presented with profuse hemorrhage and other signs suggesting an acute leukemia. Histologic and cytogenetic evaluation of her bone marrow revealed alveolar rhabdomyosarcoma as the underlying cause of massive disseminated intravascular coagulation and hyperfibrinolysis. A review of the literature reveals that coagulopathy appears to be a common feature of alveolar rhabdomyosarcoma.
