In a non-randomized study the efficacy of itraconazole in preventing fungal infections in neutropenic patients was investigated. Forty-seven patients with acute leukemia or advanced lymphoblastic lymphoma were enrolled. Ninety-two episodes of severe neutropenia after chemotherapy were observed. Mean duration of neutropenia was 24 days. Norfloxacin was administered as prophylaxis against gram-negative infections and itraconazole 200 mg b.i.d. as antifungal prophylaxis. Surveillance cultures of throat, urine, feces and vagina or prepuce were performed regularly. Four patients died, two patients due to heart failure, two patients due to staphylococcal pneumonia. Only in one case Candida albicans was cultured from bronchoalveolar lavage fluid. No systemic mycosis or Aspergillus fumigatus pneumonia was documented. In a similar group of patients treated in the preceding 18 months nystatin was used as antifungal prophylaxis. In this group of patients six cases of Aspergillus fumigatus pneumonia, two cases of Candida albicans fungemia and one case of Candida glabrata pneumonia occurred of which six patients died. Itraconazole seems to be effective in preventing fungal infections in neutropenic patients and is well tolerated.

The role of amsacrine in inducing remission in patients with cardiac disease and acute leukemia was evaluated. There were 17 patients with acute myelogenous leukemia (AML), six with acute lymphocytic leukemia (ALL), and one with biphenotypic leukemia. In this series of 24 patients whose disease had relapsed and who had reduced left ventricular ejection fraction, nine had a complete remission, seven with AML and two with ALL. In addition, four of six with newly diagnosed acute leukemia and reduced left ventricular ejection fraction also responded. Among nine patients who underwent endomyocardial biopsy, none had morphologic changes of sufficient degree to account for drug-induced heart failure. Patients with preexisting arrhythmias received amsacrine without incident if their serum potassium level was higher than 4.0 mEq/l at the time of drug administration. Amsacrine is safe and effective therapy for patients with acute leukemia and cardiac disease.

(2'' R)-4'-O-Tetrahydropyranyl Adriamycin (THP) is a new antitumor agent discovered among series of similar anthracycline compound synthesized by Umezawa et al. Phase I study revealed dose limiting factor of leukopenia with upper GI toxicity. Alopecia, cardiac failure and transient hepatic failure were extremely mild. Definite responses were demonstrated in acute leukemia, lymphoma, ovarian carcinoma, head and neck carcinoma, breast carcinoma and GU carcinoma. Pharmacokinetic studies revealed rapid cell uptake and outputs in bile (20%) and urine (8%) in 24 hours. Transfer to third spaces were poor but definite. In vivo a part of THP was converted to ADM in the liver, but not in other tissues including tumors. THP would be an extremely interesting compound, because of comparable spectrum of responses to various tumors with extremely low toxicity compared with other anthracycline compounds.

Twenty courses of carminomycin were administered to 18 evaluable adult patients with acute leukemia (14 ANLL, 2 ALL, 2 CGL-BC). All but one received daily doses of 6-14 mg/m2 for 5 consecutive days. Two patients older than 60 yr had not prior chemotherapy and the others had refractory or relapsed disease. The median age was 60 yr. Three ANLL patients achieved complete remission for 8, 9 and 9 months respectively, with no maintenance therapy. None of these had proven clinical resistance to daunomycin and/or doxorubicin. Mucositis was dose-related and dose-limiting. Nausea and vomiting were rare. Alopecia was constant. Cardiac arrythmia was ascribed to carminomycin in two patients. One episode of cardiac failure seemed clearly drug-related and recovered with symptomatic treatment. In conclusion, encouraging antileukemic activity was observed with carminomycin in poor-risk patients. At doses up to 12 mg/m2 day X 5, extramedullary toxicity remained acceptable.

Anthracycline antibiotic (Rubidomycin and Adriamycin) are often used for treatment of acute leukemia and variety of solid tumors. The use of greater doses of these agents is mostly limited by the damage of the cardiac muscle and by heart failure. The Rubidomycin cardiac toxicity analysis of children with acute leukemia has been considered in this paper. The results were obtained by investigating 53 patients who received this drug. They were classified in subgroups in relation to the total dose administered. Acute or chronic myocardial damage appeared in 6 children. The subgroup incidence of damage is directly proportional to the total dose administered.

An attempt was made to see if new forms of treatment of fungal and bacterial septicemia, or new cytostatic combinations have changed the causes of death in leukemia and lymphoma. Autopsies were studied of 16 cases with acute leukemia, 2 with chronic granulocytic leukemia and 24 with lymphoma. 10 of the 18 patients with leukemia and 10/14 lymphoma patients died although they had no, or only slight, tumor infiltration in the bone marrow and parenchymatous organs; only 1/18 leukemias had extensive infiltration. There was a statistically significant correlation between the extent of marrow and organ infiltration. Cardiac failure (5/18 patients) was almost as common as the main cause of death as septicemia (7/18) in leukemia. The corresponding figures in lymphoma were 5/24 and 9/24, respectively. The present findings contrast with earlier ones, where more septicemia and tumor infiltration were found at autopsy, and less cardiac failure was observed. 15 of 16 cases with septicemia at autopsy had terminal fever. Bacteriological and histological signs of septicemia at autopsy agreed satisfactorily. There was a surprising absence of agreement between terminal granulocytopenia and septicemia; 13 of 16 patients with septicemia had over 0.1 x 10(9) and 10 over 0.5 x 10(9) granulocytes/liter blood.

We describe a case of Philadelphia-negative essential thrombocythemia in whom bcr-abl hybrid messenger RNA was detected. The patient suffered from frequent splenic infarctions and myelofibrosis. Interestingly, a transformation to acute leukemia which was commonly seen in patients with bcr-abl-positive chronic myelogenous leukemia did not occur until he died from heart failure due to severe anemia 8 years after the diagnosis. The heterogeneity of bcr-abl-positive thrombocythemia is emphasized.

Interferon (IFN) is effective in treating adults as well as children with chronic hepatitis C. We investigated the efficacy of IFN therapy in 13 children with underlying acute leukemia who had chronic hepatitis C (age range, 5 to 17 years; mean age, 9.9 years). Natural IFN- alpha was administered at a dose of 0.1 mega unit (MU)/kg (maximum dose, 6.0 MU) daily for 2 weeks and then three times per week for an additional 22 weeks (total dose, 8 MU/kg). IFN treatment was initiated at least 2 years after the completion of treatment for acute leukemia. A complete response was obtained in 5 children (38%). The serum level of anti-hepatitis C virus core antibody was closely related to the response to IFN. IFN therapy was well tolerated by all but 1 of the children, who developed mild transient heart failure 4 months after the initiation of therapy. IFN therapy for children with chronic hepatitis C who had underlying acute leukemia was beneficial. However, further trials are required to confirm the safety and improve the dosage schedule of IFN therapy.

In order to examine the effect of hematopoietic stem cell transplantation (HSCT) on cardiac systolic function, we measured left ventricular ejection fraction (LVEF) by radioventriculography (RVG) before and after the transplantation procedure. One hundred and forty-eight patients were examined, 96 undergoing allogeneic grafting and 52 autologous. Fifty patients had CML, 48 AML, 21 ALL, 18 multiple myeloma and 11 breast cancer. The second RVG examination was performed 22 to 227 days (median 60 days) after HSCT. The mean LVEF value in the whole patient group was 60.2% (range 39-81%) before and 61.1% (35-86%) after transplantation. Patients with CML had significantly higher LVEF before transplantation than patients with acute leukemia (P = 0.007) and multiple myeloma (P = 0.005). No significant changes in mean LVEF between the pre- and post-transplant measurements were seen in any of the diagnostic subgroups or in allogeneic or autologous recipients. None of the 148 patients in the study has shown any signs of clinical heart failure at 2, 5 to 10 years follow-up. Patients who had received anthracyclines in the previous treatment had significantly lower LVEF before transplantation but showed no increased risk of decline in cardiac function. In conclusion, the HSCT procedure does not seem to affect myocardial function 1-7 months after transplantation.

Anthracyclines are effective antineoplastic drugs, but they frequently cause dose-related cardiotoxicity. The cardiotoxicity of conventional anthracycline therapy highlights a need to search for methods that are highly sensitive and capable of predicting cardiac dysfunction. We measured the plasma level of brain natriuretic peptide (BNP) to determine whether BNP might serve as a simple diagnostic indicator of anthracycline-induced cardiotoxicity in patients with acute leukemia treated with a daunorubicin (DNR)-containing regimen. Thirteen patients with acute leukemia were treated with a DNR-containing regimen. Cardiac functions were evaluated with radionuclide angiography before chemotherapies. The plasma levels of atrial natriuretic peptide (ANP) and BNP were measured at the time of radionuclide angiography. Three patients developed congestive heart failure after the completion of chemotherapy. Five patients were diagnosed as having subclinical heart failure after the completion of chemotherapy. The plasma levels of BNP in all the patients with clinical and subclinical heart failure increased above the normal limit (40 pg/ml) before the detection of clinical or subclinical heart failure by radionuclide angiography. On the other hand, BNP did not increase in the patients without heart failure given DNR, even at more than 700 mg/m(2). The plasma level of ANP did not always increase in all the patients with clinical and subclinical heart failure. These preliminary results suggest that BNP may be useful as an early and sensitive indicator of anthracycline-induced cardiotoxicity.
