Cancer chemotherapeutic agents and antibacterial antibiotics are often given concomitantly. Daunorubicin, cytosine arabinoside, and three antibiotics (gentamicin, amikacin, and ticarcillin) were tested individually and in combinations to determine their antimicrobial activity against Pseudomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli. These cytotoxic agents are commonly employed in the therapy of acute nonlymphocytic leukemia for remission induction therapy, and these antimicrobial agents are used in infection therapy. The maximum concentrations of the two cytotoxic drugs were chosen to be twice the known peak plasma levels of commonly employed dosage schedules. Neither of the cancer chemotherapeutic agents, alone or in combination, demonstrated bactericidal activity at the levels tested. However, in the presence of these agents, the antimicrobial activity of gentamicin and amikacin, although not that of ticarcillin, was depressed for 11 of 15 K. pneumoniae strains and 8 of 15 P. aeruginosa strains, but for none of the strains of E. coli. This level of decreased activity occasionally resulted in a minimal inhibitory concentration of the tested aminoglycoside well above the standard serum levels. Daunorubicin was more likely to antagonize gentamicin than was cytosine arabinoside.

Daunorubicin, thioguanine and cytosine arabinoside were administered from the 17th to 34th weeks of pregnancy in a 23-year-old patient with acute myeloid leukaemia. The patient went into remission of her leukaemia, and a normal male infant was born after labour was induced in the 40th week. This experience supports the view that modern regimens of anti-leukaemic drugs may be administered during the second and third trimesters of pregnancy without harmful effects on the foetus.

Complete remission (CR) rates of 80% are achieved with the AML-BFM protocols but one third of patients relapse within the first three years. There are few reports of treatment of relapsed childhood AML, and these deal with the evaluation of new drugs for frontline therapy. We performed a retrospective analysis to investigate how patients previously treated with the AML-BFM-83 protocol were treated after relapse and how many long term remissions were achieved. 48 of 139 patients relapsed after having achieved complete remission with the AML-BFM-83 protocol which consists of continous infusion of ARA-C 100 mg/m2 day 1-2, ARA-C 200 mg/m2 day 3-8, Daunorubicin 60 mg/m2 day 3, 4, and 5, and VP-16 150 mg/m2 day 6, 7, and 8, and an 8 week consolidation therapy consisting of Prednisolone, Thioguanine, Vincristine, ADR, ARA-C, Cyclophosphamide, intrathecal ARA-C and cranial irradiation followed by maintenance therapy. Duration of first remission ranged from 1.5 months to 66.3 months. Excluding 5 children with either isolated or combined extramedullary relapses and another 4 patients for missing data, 39 children were evaluable. 20 children received no therapy or palliative therapy while 16 patients received chemotherapy and another 3 children were transplanted in relapse. Although 9 different intensive chemotherapy regimens were used for reinduction, a high number (12 of 16 = 75%) of second complete remissions was achieved. Several therapeutic options were used to maintain a second remission: regular maintenance therapy (7 patients), allogeneous bone marrow transplantation (BMT) (2 patients), autologous BMT (3 patients).(ABSTRACT TRUNCATED AT 250 WORDS)

From 1987 to 1990, intensive postremission chemotherapy was compared to autologous bone marrow transplant in previously untreated children with AML who received identical induction therapy with two courses of Daunorubicin (DNR) and conventional dose ARA-C (protocol AIEOP LAM 87). Overall, 121 of the 155 eligible patients achieved complete remission (CR) (78%). Patients in CR who lacked HLA-MLC compatible donor were randomized to receive either autologous BMT (Auto-BMT) or further sequential postremission therapy. Patients with HLA-MLC compatible donor were assigned to allogeneic BMT (Allo-BMT). Projected 3-years disease free survival (DFS) are 58% for Allo-BMT group, 24% for Auto-BMT group, 26% for chemotherapy group and 30% for a group of not randomized patients (intention to treat analysis). On March 1990 a pilot study LAM 87M was initiated. Patients in CR after induction therapy (identical to the previous protocol) receive a single intensification course consisting of high dose ARA-C plus DNR. The study continues to accrue patients.

The results of four consecutive trials designed by the GIMEMA group for the treatment of ANLL in elderly patients are reviewed. Complete remission (CR) has been achieved in 20.8% of patients older than 60 years treated with 5-day courses of ARA-C plus thioguanine, in 22.7% of patients treated with high dose ARA-C (HDARAC) plus Asparaginase, in 39.5% of patients aged 55 to 80 receiving either Idarubicin or Daunorubicin in combination with Cytarabine in a standard 3+7 protocol and in 51% of patients older than 60 years treated with intermediate dose ARA-A (IDARAC) plus Mitoxantrone. From 1988, patients ineligible for aggressive chemotherapy entered a study of palliative treatment with Thioguanine and ARA-C. This 18 year GIMEMA experience showed that: CR can be obtained only with regimens producing marrow aplasia, the inclusion of anthracyclines or Mitoxantrone improves the CR rate, without prohibitive toxicity, haematological toxicity is very high in elderly patients and account for the most frequent cause of treatment failure namely death in aplasia, palliative treatment does not improve the quality of life and prolongs median survival only slightly. When comparing the results of these trials, it appears that in the GIMEMA group the capability of offering effective treatment to elderly patients with ANLL has continuously improved and that IDARAC plus Mitoxantrone is so far the most active and best tolerated regimen. Death in aplasia remains a major problem and future trials will be aimed at exploiting the possibility of reducing the haematological toxicity by using recombinant colony stimulating factors.

Treatment of acute myelogenous leukemia (AML) is divided into remission induction and post-remission therapy. Remission induction is usually with cytarabine and an anthracycline. Daunorubicin is commonly used but recent data suggest idarubicin or mitoxantrone are equally effective, possibly better. High-dose cytarabine has also been used for remission induction but is not proven superior. Post-remission treatment is typically with two or more courses of drugs similar to those used for remission induction. Other studies use non-cross resistant drugs and/or high-dose cytarabine. Although some data favor use of high-dose cytarabine, no approach is clearly superior. There is considerable controversy whether persons in first remission and with an HLA-identical sibling should receive a bone marrow transplant immediately or after relapse. Although transplant results appear superior, especially in persons less than 20 years of age, the most effective strategy may be reserving transplants for persons failing chemotherapy. This strategy also applies to persons receiving autologous transplants or transplants from alternative donors, like HLA-matched related or unrelated persons.

From 1982 to 1990, 340 children with newly diagnosed ANLL entered two consecutive AIEOP trials: LAM 8204 (1982-1987) and LAM 87 (1987-1990). Patients in both studies received identical remission induction with Daunorubicin and ARA-C. In the first study (LAM 8204) 167/171 patients were consolidated with four courses of DAT, followed by six additional courses of continuation therapy with three drug pairs given sequentially. Periodic intra-thecal ARA-C was used for CNS prophylaxis. For patients remaining on protocol, the OFS and EFS probability at 8 years was 35% and 30%, respectively. Induction response and EFS were adversely predicted by FAB MS subtype and hyperleukocytosis. In LAM 8204 trial there were 30 withdrawals represented by patients undergoing allogeneic (14) or autologous (16) BMT. For these patients the DFS probability at 5 years was 64% and 50%, respectively. On LAM-87 trial, 136/169 patients were evaluable and 98 (76%) attained CR. After consolidation with one course of DAT, patients with an HLA-identical donor underwent allogeneic BMT and those lacking a matched donor were randomized to receive either autologous BMT or the LAM 8204 postremission chemotherapy. The 2-year probability of DFS for allografted patients was 76% significantly higher (P = 0.0001) than that observed for patients on chemotherapy (12%) or autologous BMT (31%) arms.

Clinicopathological and cytogenetic features of two patients with acute myelogenous leukemia (AML) whose blast cells coexpressed myeloid-associated antigens and CALLA are described. Leukemia cells revealed myelomonocytic (FAB-M4) and monocytic (FAB-M5) features, while the nonblast cell population exhibited trilineage myelodysplasia in both cases, a finding suggestive of multiple-cell-lineage involvement. Cytogenetically, a deletion of the long arm of chromosome 6 was found in one patient, and normal metaphases were detected in the other. Molecular studies disclosed a rearrangement of the IgH locus in one patient. Clinically, these patients were unresponsive to antimyeloid regimens including Daunorubicin and Cytarabine, two agents normally also effective on lymphoblastic leukemias, possibly indicating the need for alternative protocols for the treatment of CALLA positive AML.

Idarubicin is a new derivative of Daunorubicin which was found to be more potent and more active than Daunorubicin and Doxorubicin in several experimental leukemias. Its antileukemic activity in preclinical models prompted the introduction of Idarubicin into clinical studies. As a single agent, Idarubicin produced complete remission in 20% and 30% of patients with heavily pretreated pediatric and adult acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) respectively. Idarubicin combined with Cytarabine and/or other antileukemic agents produced complete remissions in 46% of patients with refractory or relapsed AML and in 58% of patients with refractory or relapsed ALL (adult and pediatric). Subsequently, Idarubicin has been employed in untreated AML patients in combination with Cytarabine and/or Etoposide, producing complete remissions in more than 80% of patients. In ALL patients the drug has been used in combination with Vincristine, Cytarabine and Prednisone, producing complete remissions in 82% of patients. Recently, Idarubicin has been utilized in combination with intermediate doses of Cytarabine in refractory or relapsed ALL and AML, and 70% of patients achieved complete remission. Preliminary results of ongoing prospective randomized studies in untreated adult AML seem indicate that Idarubicin is at least equivalent, if not superior to Daunorubicin. The antileukemic activity of Idarubicin given orally as single agent, or in combination with other drugs, has been shown in AML and myelodysplastic syndromes. The toxicity of Idarubicin includes mild nausea and vomiting, alopecia and liver dysfunction. Ongoing randomized trials comparing Idarubicin to Daunorubicin should provide more information about the potential cardiotoxicity of this drug.

One hundred ninety six previously untreated patients of adult acute nonlymphocytic leukemia (ANLL) were treated with B-DOMP therapy. 102 patients were treated in the conventional rooms and 94 patients were in the laminar airflow rooms. The complete remission (CR) rates were 78.4%, and 84.0% respectively. The CR rate of the groups whose age was 60 years or older was higher for the patients treated in the laminar airflow room than those is conventional rooms (75.8% versus 60.0%), and the fatality from fungal infection was substantially lower for the laminar air-flow room patients. Non cross resistant chemotherapy based on alternate administration of Daunorubicin (DNR) and Aclarubicin (ACR) was given to 54 patients with ANLL in remission. The median duration of remission was 48.0 months, with 38.4%, patients in remission at 8 years. A plateau phase indicating freedom from the risk of leukemic recurrence is not clearly apparent yet. The most serious toxicity was drug induced cardiotoxicity from increased total dose by long term maintenance therapy. Newly planned post remission chemotherapy that incorporated Etoposide and Mitoxantrone with ACR and DNR was given to 35 patients with ANLL in remission. Seventy nine percent (79%) of patients were remaining in remission at 2 years. Because many patients experienced significant side effects after each course of therapy, intensive post remission chemotherapy should be used in a setting where the physician is always attending and ready to serve the patients.
