Autoimmune thrombocytopenia after six cycles of fludarabine phosphate in a patient with chronic lymphocytic leukemia.

Fludarabine phosphate (FDR) has demonstrated a remarkable clinical activity in chronic lymphocytic leukemia (CLL). Myelosuppression is the main toxicity although autoimmune hemolytic anemia (AIHA) is frequently reported. The pathogenesis of AIHA is still unknown however the role of T-cell immunosuppression is suspected. One case of thrombopenia after FDR has been described in a patient with a previous history of an autoimmune thrombocytopenia. We here report a 73-year-old man with a B-CLL and no previous autoimmune disorder who received six courses of fludarabine phosphate and developed afterwards an autoimmune thrombocytopenia.

Analysis of platelet recovery after autologous transplantation with G-CSF mobilized CD34+ cells purified from leukapheresis products.

We studied platelet recovery in relation to graft content in CFUs and CD34+ cells in 31 patients with multiple myeloma (21) or non-Hodgkin lymphoma (10) receiving marrow-ablative therapy followed by autologous transplantation with G-CSF mobilized CD34+ cells purified from leukapheresis products. Twelve patients had prolonged post-transplantation thrombopenia (> or = 14 days): their graft contents in CD34+ cells, CFU-GM and BFU-E were significantly inferior to those of patients with rapid platelet recovery. Although numbers of infused CD34+ cells and CFU-GM or BFU-E were well correlated, the graft content in CD34+ cells was the only parameter predictive of platelet recovery (r = -0.38, p = 0.04), with a threshold of 2.5 x 10(6) CD34+ cells/kg. However, because rapid platelet reconstitution was obtained for 4 of 16 patients re-infused with < 2.5 x 10(6) CD34+ cells/kg, we investigated whether the graft CFU-MK content might be a better predictor of platelet reconstitution than the CD34+ cell content. Eighteen CD34 grafts were studied for CFU-MK content: CD34 and CFU-MK contents were weakly correlated (r = 0.52, p = 0.03), but there was no correlation between numbers of infused CFU-MK and time to platelet recovery. We conclude that, for autologous CD34 grafts, CFU-MK assays, like CFU-GM or BFU-E assays, cannot be used to predict platelet recovery. A CD34+ cell content > or = 2.5 x 10(6)/kg remains the only reliable indicator of the platelet reconstitution capacity of a CD34 graft.

[Safety and efficacy of interferon alfa-2b in the adjuvant treatment of uveal melanoma].

PURPOSE: In this manuscript, the safety and efficacy of adjuvant interferon alfa 2b treatment of uveal melanoma is described. PATIENTS AND METHODS: A total of 39 patients (23 male and 16 female, mean age 56.5 years, range 35-78 years) with uveal melanoma were treated with interferon alfa 2b, 3 million units three times a week subcutaneously for 1 year after therapy of the primary tumor. In all patients age, gender, primary melanoma data, therapeutic interventions, treatment side effects and outcome were documented. RESULTS: Of the 39 patients, 31 (80%) finished the treatment as scheduled after 1 year. In 18 patients (46%) the initial dose had to be reduced due to leucopenia, thrombopenia, cardiac symptoms, elevated of liver function or vertigo (WHO grade I-III). In eight patients, therapy had to be withdrawn because of serious side effects (five patients) and the appearance of metastases (three patients). Neither a univariate approach nor a multivariate approach could show a protective effect of interferon treatment on survival. CONCLUSIONS: Adjuvant treatment of uveal melanoma with interferon alfa should be abandoned until the question of dose and administration for cutaneous melanoma is solved.

[Rheumatic and hemato-/oncological disorders].

The association of rheumatic diseases with common and some of the less common hematological features such as different forms of anemia, leukopenia and thrombopenia are described in this article. In addition, the occurrence of malignancy in rheumatoid arthritis, systemic lupus erythematosus, myositis and scleroderma and possible causes are discussed. On the other hand, this review also focuses on various rheumatological manifestations of hematological diseases such as leukemia and lymphoma. The aim of the article is to give an overview of the various associations between rheumatological and hemato-/oncological diseases that have to be considered in clinical practice.

Regression of brain metastases from breast carcinoma after chemotherapy with bendamustine.

PURPOSE: Bendamustinehydrochloride (bendamustine) is an alkylator with anticipated antimetabolic activity. It has shown activity in malignant lymphoma and breast cancer. Up to now there are no reports about the activity of bendamustine in the treatment of brain metastases. We report on a 38-year-old woman with brain metastases from breast cancer. The first diagnosis of an invasive ductal, hormone receptor negative breast cancer was made in October 1997, stage pT1c pN2 (11/11)cM0 - G3. After lumpectomy and resection of axillary lymph nodes, the patient received adjuvant chemo- and radiotherapy. Twenty six months after the first diagnosis, bone metastases occurred and were treated with radiotherapy. One month later, multiple liver metastases developed which were treated with trastuzumab and paclitaxel. Four months later, progress of the liver metastases and malignant infiltration of bone marrow with thrombopenia occurred. METHODS: Chemotherapy with bendamustine at a dose of 150 mg/m(2) on day 1 and 2 was initiated. Two days later, the patient suffered from central facial palsy and subsequent computed tomography (CT) revealed three brain metastases in the frontal, parietal and occipital region. Because of the advanced liver metastases with clinical and laboratory signs of liver insufficiency and the reduced performance status of the patient, chemotherapy with bendamustine was continued and no local treatment of the brain metastases was performed. RESULTS: After two courses of bendamustine, ultrasound showed regression of the liver metastases. Liver enzymes decreased, platelets increased, and the patient's performance status improved. Additionally, two of the three brain metastases were no longer detectable by CT, the third had decreased compared to the time of diagnosis. CONCLUSION: To the best of our knowledge, this is the first report describing major activity of bendamustine in cerebral metastases. Thus, it may be considered as another therapeutic strategy against metastatic brain cancer. However, this finding warrants further investigation in clinical trials.

Phase I/II trial of human recombinant granulocyte-colony-stimulating factor (filgrastim) and escalating doses of cyclophosphamide, mitoxantrone, and 5-FU in the treatment of advanced breast cancer.

PURPOSE: We performed a phase I/II dose-escalation trial of cyclophosphamide, mitoxantrone, and 5-fluorouracil (CNF) in combination with human recombinant granulocyte-colony-stimulating factor (G-CSF, filgrastim) in patients with advanced breast cancer. The objectives of this trial were (1) to gain experience with filgrastim given to patients with advanced breast cancer and receiving standard-dose CNF, and (2) to determine the maximum tolerated dose of CNF that could be given with filgrastim support by incremental dose escalation of two components of the CNF regimen, cyclophosphamide and mitoxantrone. METHODS: Four patients who had received prior therapy for advanced disease received standard-dose CNF with filgrastim support. Sequentially enrolled patients who had received no prior chemotherapy for advanced disease were treated with standard-dose CNF without filgrastim (5 patients), standard-dose CNF with filgrastim (15 patients), or were entered into sequential cohorts of 3-6 patients to be treated with increasing doses of CNF with filgrastim support (29 patients). RESULTS: The maximum tolerated doses that could be given with filgrastim support were 1500 mg/ml cyclophosphamide, 20 mg/m2 mitoxantrone, and 500 mg/m2 5-FU. Overall, 7 complete (14%) and 13 partial responses (26%) were observed. Despite the use of filgrastim, repeated cycles of CNF at doses of 2000 mg/m2 cyclophosphamide, 25 mg/m2 mitoxantrone, and 500 mg/m2 5-FU could not be given because of neutropenia and thrombopenia. Among 18 patients with bidimensionally measurable disease there were 3 complete (17%) and 5 partial (28%) responses. The median progression-free survival of all patients was 236 days (34 weeks). CONCLUSION: The use of filgrastim allows CNF to be given at approximately twice the dose intensity of "standard"-dose CNF. Because nonhematopoietic toxicity was not dose-limiting, further dose escalation of this regimen might be possible with more effective hematopoietic support. The response rate and survival of patients treated in this study were within the range expected with standard-dose chemotherapy.

Antitumoral activity of oxaliplatin/cisplatin-based combination therapy in cisplatin-refractory germ cell cancer patients.

PURPOSE: Only 20-30% of patient with advanced germ cell tumors, relapsing after standard first-line therapy, are curable with current second-line cisplatin-based regimens. New salvage combinations incorporating new active agents are needed. We report the toxicity/tolerance of a new salvage regimen based on the oxaliplatin (Eloxatin)/cisplatin combination, evaluated in patients with recurrent, mostly cisplatin-refractory germ cell tumors. PATIENTS AND METHODS: Thirteen patients were enrolled in this study. All except one had received cisplatin-based chemotherapy. Eight had progressive disease as the best response on their last platinum-based chemotherapy, and three had potentially sensitive tumors. The median interval since the last platinum-based chemotherapy was 6 months (range: 1-36 months). One untreated patient with poor prognosis was also enrolled. Twelve patients had pathological markers [median alpha-fetoprotein 14 800 ng/ml (58-10(6)), median human chorionic gonadotrophin beta subunit 7000 IU/ml (37-723 700)]. Patients received either oxaliplatin (130 mg/m(2)) and cisplatin (100 mg/m(2)) every 3-4 weeks (Bi regimen, four patients), or the same regimen combined with one to four of the following cytotoxic agents: ifosfamide, epirubicin, vinorelbine, methotrexate, dactinomycin, etoposide and bleomycin (BiC regimen, 9 patients). Treatment was individualized according to each individual patient's pretreatment and clinical characteristics. RESULTS: Seven objective responses were obtained (overall response rate = 54%), all with the BiC regimens (two complete and five partial responses). Two patients with recurrent disease achieved a long-term complete response lasting over 5 years. Four partial responders were seen in the eight cisplatin-refractory tumors, lasting 4-8 months. All objective responses had a corroborating major decrease in tumor marker blood levels (median decrease: 99.7%). The median survival for the whole group was 8 months. The commonest severe toxicity was hematological (grade 4 neutropenia in 78% and thrombopenia in 74% of the BiC cycles). CONCLUSION: Our combined salvage regimen induced significant antitumoral activity in recurrent, cisplatin-refractory germ cell tumors. Oxaliplatin merits further evaluation as a component of combination therapy for this disease.

Impact of hematological diagnosis on early and late outcome after laparoscopic splenectomy: an analysis of 111 cases.

BACKGROUND: Laparoscopic splenectomy (LS) is now regarded as the treatment of choice for autoimmune thrombopenia (ITP). However, there have been few reports describing the application of LS to other splenic diseases, such as malignant entities and conditions associated with splenomegaly. Hematological diseases have specific clinical features that can influence immediate outcome after LS. Although the long-term effects of LS are unknown, a risk of splenosis has been suggested. Therefore, we designed a study to analyze the impact of primary hematological disease on immediate and late outcome in a prospective series of LS patients. METHODS: We performed a prospective analysis of 111 LS done between February 1993 and March 1999. The patients were classified by hematological indications into the following four groups: (a) group 1, low platelet count. This group was further subdivided into group 1A, idiopathic thrombocytopenic purpura (ITP) (n = 48) and group 1B, HIV-related ITP (n = 8); (b) group 2, anemia. This group was further subdivided into group 2A, autoimmune hemolytic anemia (n = 8), and group 2B, spherocytosis (n = 11); (c) group 3, malignancy (n = 28); and (d) group 4, others (n = 8). Immediate outcomes were recorded prospectively. Hematological status and late complications were reviewed after a mean follow-up of 24 +/- 18 months. RESULTS: There were no significant differences between the groups in terms of conversion, transfusion requirements, and morbidity, although transfusion and morbidity were slightly higher in group 3. However, hospital stay was significantly longer in groups 3 and 4 than in groups 1 and 2. Long-term follow-up showed satisfactory hematological results in >/=75% of patients (group 1A, 82%; group 1B, 88%; group 2A, 88%; group 2B, 100%; group 3, 75%; group 4, 88%). Overall, late morbidity was 8.3% and mortality was 6.2%, mainly due to deaths in group 4 (six of 22 patients). CONCLUSION: LS is a safe and reproducible procedure for most hematological indications, with a similar immediate outcome for benign diseases and a long-term hematological response comparable to the standard results that have been observed in open series.

Major response and clinical benefit following third-line treatment for Bellini duct carcinoma.

Bellini duct carcinoma accounts for 1-3% of all renal carcinomas and is characterized by an aggressive course and extremely poor prognosis. Conventional treatment for renal-cell carcinoma seems to be ineffective. Since the histology of Bellini duct carcinoma is similar to urothelial carcinoma, chemotherapy for urothelial cancer might be more promising than conventional treatment. We present a patient with renal carcinoma of the left kidney who underwent laparoscopic extrafascial nephrectomy and adrenalectomy. Histopathologic work-up showed Bellini duct carcinoma (pT3a, NX, G3, R0 and M0). Eight months after surgery, disease progression was observed with local recurrence, multiple pulmonal lesions, para-aortic and aortocaval lymphadenopathies and a solitary bone lesion. First-line treatment with interferon-alpha and interleukin-2, as well as second-line treatment with thalidomide, were ineffective. Disease progressed rapidly and the patient experienced a dramatic reduction in performance status and quality of life. Six courses of chemotherapy with cisplatin and gemcitabine were given, a treatment reported to be highly active in urothelial cancer. The treatment was well tolerated, with thrombopenia WHO grade II, anemia WHO grade I and nausea/vomitus WHO grade II being the most severe side effects. Follow-up computer tomography revealed partial remission with 50-100% response at the different sites of metastasis. This response was accompanied by a dramatic improvement in performance status (from an initial 60% to 100% Karnofsky index) and quality of life. The combination of cisplatin and gemcitabine was highly active in this patient with metastatic Bellini duct carcinoma, even given as third-line treatment. This regimen fulfils all criteria for palliative treatment, as our patient showed an impressive improvement in WHO performance status and therefore in quality of life. Histopathologic characteristics should be a major criterion for treatment strategy in renal carcinoma, particularly in Bellini duct carcinoma.

Dose escalation study of docetaxel and nedaplatin in patients with relapsed or refractory squamous cell carcinoma of the esophagus pretreated using cisplatin, 5-fluorouracil, and radiation.

BACKGROUND: Definitive chemoradiation with cisplatin (CDDP) and 5-fluorouracil (5FU) has been playing an important role in the treatment of esophageal cancer, but some patients are not curable or have recurrent lesions. However, few chemotherapeutic regimens are available for such patients. Docetaxel and nedaplatin are active for esophageal cancer. We conducted a dose-escalation study of docetaxel and nedaplatin as second line-chemotherapy after definitive chemoradiation in patients with relapsed or refractory squamous cell carcinoma of the esophagus after chemoradiation. METHODS: Nedaplatin was administered on day 1 and docetaxel was administered on days 1 and 15, every 4 weeks. Dose escalation was based on the dose-limiting toxicity (DLT) observed during the first cycle. RESULTS: Twelve patients were enrolled. At a docetaxel dose of 30 mg/m(2) and a nedaplatin dose of 80 mg/m(2), one grade 4 neutropenia occurred and caused one treatment break longer than 2 weeks, but there were few DLTs. At doses of 35 and 80 mg/m(2), respectively, two grade 4 neutropenias and one grade 2 thrombopenia occurred and caused three treatment breaks longer than 2 weeks. Therefore, the maximum tolerated dose was established at this dose level. Two grade 3 anorexias and one grade 3 nausea occurred, but other non-hematological toxicities were generally mild. Responses were seen in one-fourth of the 12 patients, including one complete remission. CONCLUSION: The recommended doses of docetaxel and nedaplatin were 30 and 80 mg/m(2), respectively. This combination could be a potential second-line treatment for this target population.

A case of systemic lupus erythematosus expressing intractable thrombocytopenia remedied effectively by intermittent and continuous administrations of a small amount of immune globulin.

We describe a case where intermittent and continuous administrations of a small amount of immune globulin were effective in the treatment of refractory chronic immune thrombocytopenic purpura by systemic lupus erythematosus (SLE). Steroid pulse therapy and cyclophosphamide pulse therapy were considered for thrombopenia. However, the patient had compressed fracture of the lumbar vertebrae due to osteoporosis and right external malleolus ulcer with complications of infection. Therefore, high-dose intravenous immune globulin (IVIG) therapy (400 mg/kg daily for 5 consecutive days) was administered. Then, as a maintenance therapy, a small amount of 400 mg/kg for 1 day (400 mg/kg monthly) was given in an intermittent and continuous manner, which resulted in improvement of thrombocytopenia and reduction of the amount of steroid administered.

Concurrent chemoradiotherapy and adjuvant chemotherapy with Topotecan for patients with glioblastoma multiforme.

PURPOSE: The prognosis for patients with glioblastoma multiforme remains poor. Phase II studies, meta-analyses and a phase III study show that concurrent chemoradiotherapy has an advantage over irradiation alone. In this study the effectiveness of concurrent chemoradiotherapy with Topotecan and an adjuvant chemotherapy with Topotecan was investigated. PATIENTS AND METHOD: Forty-two patients with predominantly unfavourable prognosis factors were included in the study and treated as follows: hyperfractionated accelerated radiotherapy (2x1.75Gy to 45.5 + 12.25 Gy (RP)) with a concurrent, continuous infusion of Topotecan (0.5 mg/m(2)/d, days 1-21). On day 28 the adjuvant chemotherapy (three courses) was begun according to the same scheme. RESULT: Haematological toxicities were 13/42 (30%) grade III leucopenia, 2/42 (4%) grade IV, as well as 5/42 (10%) grade III thrombopenias and 1/42 (2%) grade IV. 30/42 (71%) patients showed improvement or stabilisation of an existing neurological symptomatic complex. The median time to progression was 7.2 (+/- 0.8) months, the median total survival was 10 (+/- 1.2) months, the 2 year survival rate 4.7 (+/- 0.3)%. Prognostic factors were age, surgical radicality, performance status and the tumour volume before therapy. SUMMARY: Concurrent chemoradiotherapy and an adjuvant chemotherapy with Topotecan is feasible at acceptable toxicity levels also for patients with a moderate performance status. The patients benefit from the improvement of the clinical symptomatic complex and, even with unfavourable prognosis factors, have a higher median survival in comparison to data published on similar groups of patients given only radiotherapy.

Prevention of upper gastrointestinal bleeding in long-term ventilated patients. Sucralfate versus ranitidine.

Thirty-two long-term ventilated patients were randomly selected for a study of the efficacy of sucralfate (1 g six times per day via gastric tube) versus ranitidine (six 50-mg to six 100-mg doses per day intravenously) for the prevention of upper gastrointestinal bleeding. The patients of the two treatment groups (each 16) were comparable with respect to diseases precipitating acute respiratory failure and risk factors of bleeding, e.g., renal failure, thrombopenia, coagulopathy, and anticoagulant treatment. Mean duration of mechanical ventilation was 7.4 in sucralfate- and 7.7 days in ranitidine-treated patients. During mechanical ventilation, macroscopically visible bleeding developed in three of the sucralfate-treated (18.7 percent) and seven of the ranitidine-treated (43.7 percent) patients. Until the end of the study, only three of the sucralfate-treated but nine of the ranitidine-treated (56.2 percent) patients bled; the difference between the two treatment groups was at all times significant (p less than 0.05). Packed red blood cells had to be administered to the three bleeding patients in the sucralfate group and to seven bleeding in the ranitidine group. Therefore it seems that sucralfate prevented mostly minor bleeding. The high bleeding rate during ranitidine treatment was presumably due to the high number of pH-nonresponders, as almost 30 percent of the gastric aspirates of this group had a pH less than 5. During treatment no difference was found in positive blood culture specimens and bronchial secretions between the two groups. However, nosocomial pneumonia developed in two ranitidine-treated patients, whereas that complication developed in none of the sucralfate-treated patients. In long-term ventilated patients, sucralfate prevented minor upper gastrointestinal bleeding significantly better than ranitidine. However, this does not imply that major upper gastrointestinal bleeding can be prevented by either sucralfate or ranitidine in these patients.

Interference of BN 52021 (ginkgolide B) with the bronchopulmonary effects of PAF-acether in the guinea-pig.

The interaction between the ginkgolide BN 52021 and the effects of PAF-acether on the bronchopulmonary system of the guinea-pig was studied. In pentobarbitone or ethyl carbamate-anaesthetized animals, BN 52021 (1 mg/kg i.v. or 10 mg/kg p.o.) inhibited bronchoconstriction, the hematocrit increase and the accompanying thrombopenia and leukopenia induced by PAF-acether (33-100 ng/kg) and failed to block the bronchoconstriction produced by collagen, arachidonic acid and the tripeptide formyl-Met-Leu-Phe (FMLP). BN 52021, 3 mg/kg, reduced the bronchoconstriction induced by aerosolized PAF-acether. BN 52021, 300 microM, also inhibited the superoxide production by PAF-acether-stimulated alveolar macrophages and failed to reduce the same effects when triggered by FMLP (0.01-1 microM). BN 52021 blocked the formation of thromboxane-triggered by PAF-acether (100 ng) injected into perfused lung, under conditions where the effects of arachidonic acid where not modified. Finally, pretreatment of parenchyma lung strips with BN 52021 (100 microM) partially inhibited the contraction induced by PAF-acether (0.1 microM) and suppressed the accompanying release of thromboxane. BN 52021 is a selective antagonist of the effects of PAF-acether on the bronchopulmonary system and on circulating blood cells of the guinea-pig.

Homozygous hypobetalipoproteinemia with spared chylomicron formation.

Thirteen members of a family carrying a gene for pedigree of hypobetalipoproteinemia were analyzed for lipoprotein compositions, apolipoprotein (apo) B levels, and apo B isoforms. Judging from low density lipoprotein (LDL)-cholesterol (Chol) and apo B levels, a 75-year-old proband, a father who died of unknown fever, thrombopenia, and anemia, and his wife were heterozygous for hypobetalipoproteinemia. The proband had ataxic movement of hands and gait disturbance in later life. Three of four living siblings had extremely low levels of LDL-Chol (6 mg/dL) and LDL-apo B (2 mg/dL), and were postulated to have homozygous hypobetalipoproteinemia. Electrophoresis revealed marked deficiency of apo B-100, although trace amounts were noted in LDL. In contrast, apo B-48 was present in chylomicrons obtained after a fatty meal in the two patients with homozygous hypobetalipoproteinemia, indicating a selective deficiency of apo B-100 but not apo B-48. The defect in these patients seemingly is different from abnormal apo B-37 reported recently for a family with hypobetalipoproteinemia. Clinically, acanthocytotic red blood cells (8% to 12%), fatty liver, and low levels of serum lipid-soluble vitamins A and D were noted in homozygotes. One heterozygous sibling had 26 mg/dL LDL-Chol and 5 mg/dL LDL-apo B levels. All seven subjects in the third generation had low levels of Chol (85 to 140 mg/dL), LDL-Chol (40 to 63 mg/dL) and LDL-apo B (10 to 20 mg/dL). They also showed mild acanthocytosis (0.5% to 2%) and a decrease of fat-soluble vitamins in plasma.(ABSTRACT TRUNCATED AT 250 WORDS)

Risk indicators after envenomation in humans by Echis coloratus (mid-east saw scaled viper).

To determine the frequency, severity and predictors of bleeding and azotemia after envenomation in humans by Echis coloratus, a retrospective survey of 68 cases in Israel between 1970 and 1989 was carried out. We used univariate and multivariate analyses of clinical variables on admission for the outcome variables of bleeding, hemoglobin and platelet levels, and blood urea. Within hours or days after envenomation, a major bleeding episode occurred in 18% of the victims, a drop in hemoglobin to 10 g/dliter or less in 14%, and an increase in blood urea to 9 mmole/liter or more in 15%. These complications correlated with time interval between envenomation and hospital admission, and the following admission variables: degree of bleeding, hemoglobin level, platelet and white blood cell counts, blood urea and proteinuria. Complications were unlikely in patients who were presented with all of the following: a hemoglobin level of 13 g/dliter or more, a platelet count of 100,000/mm3 or more, a blood urea level of 7 mmole/liter or less, no proteinuria and no bleeding. Treatment on admission with a specific monovalent antiserum was associated with a shorter duration of hemostatic failure and a reduced incidence of anemia and thrombopenia. Infusion of fresh frozen plasma on admission did not appear to be effective in preventing complications.

High-dose platinum chemotherapy in advanced ovarian cancer: a phase II study.

From September 1986 to November 1988, 38 patients with previously untreated ovarian cancer, FIGO stages III and IV, were allocated to a study testing the efficacy of high-dose platinum delivered as combined carboplatin and cisplatin. The regimen was as follows: Day 1, 250-350 mg/m2 carboplatin and 500 mg/m2 cyclophosphamide, Day 15, 100 mg/m2 cisplatin. Overall clinical response was 60%, and complete pathologic response, verified at second-look laparotomy, was 24%. Median survival was 17 months and 3-year survival 27%. The results are similar to those obtained by a standard dose of cisplatin, cyclophosphamide, and doxorubicin. Myelotoxicity was dose limiting. After receiving four cycles, 44% of patients had grade 3 or 4 leucopenia and 65% had grade 3 or 4 thrombopenia. Despite this, dose intensity of combined cisplatin and carboplatin was between 30 and 45 mg/m2/week, expressed as cisplatin by assuming that 1 mg cisplatin equals 4 mg of carboplatin. A correlation between dose intensity and response was not found. In conclusion the study showed that the regimen is feasible, but very myelotoxic. The results were not superior to those obtained by combination chemotherapy using standard doses of cisplatin.

Possible differentiation of human acute myeloblastic leukemia cells by daily and intermittent administration of aclacinomycin-A.

A rapid decrease of myeloblasts and a remarkable increase of mature neutrophils, mostly with Pelger anomaly, were observed in the peripheral blood of a 51-year-old woman with terminal acute myeloblastic leukemia during 16 days of daily i.v. administration of 20 mg aclacinomycin-A (ACM-A). When the same dose was administered later on three consecutive days each week, a similar hematore neutrophils, mostly with Pelger anomaly, were observed in the peripheral blood of a 51-year-old woman with terminal acute myeloblastic leukemia during 16 days of daily i.v. administration of 20 mg aclacinomycin-A (ACM-A). When the same dose was administered later on three consecutive days each week, a similar hematore neutrophils, mostly with Pelger anomaly, were observed in the peripheral blood of a 51-year-old woman with terminal acute myeloblastic leukemia during 16 days of daily i.v. administration of 20 mg aclacinomycin-A (ACM-A). When the same dose was administered later on three consecutive days each week, a similar hematological change occurred again. An increase of myeloblasts observed between the third and the fifth week of this intermittent schedule was accompanied by that of mature neutrophils. Thrombopenia and anemia did not improve significantly. These findings may indicate the induction of leukemic myeloblasts by ACM-A into mature neutrophils. Administration of relatively small dose anthracyclines including ACM-A may be another potential choice in the treatment of refractory acute non-lymphocytic leukemia (ANLL) or ANLL after relapse.
