Since continuous infusion of daunorubicin and of carboplatin have shown efficacy and reduced toxicity in early phase studies in acute myeloid leukemia (AML), 34 elderly patients with high-risk AML were treated with continuous infusion daunorubicin, 30 mg/m2 per day, from day 1 to day 4, and carboplatin, 200 mg/m2 per day from day 3 to day 7. Seven patients had therapy-related AML and/or AML following a myelodysplastic syndrome at diagnosis, 15 were in first and two in second relapse, and 10 were resistant to previous anthracycline and cytarabine therapy. Nine patients or 26%, with a 95% confidence interval (CI) ranging from 18-67%, achieved complete remission, including one patient at diagnosis (14%, CI: 0-58%), seven with relapsed AML (41%, CI: 18-67%), and one with resistant AML (10%, CI: 0-45%). Median durations of neutropenia below 0.5 x 10(9)/l and of thrombocytopenia below 20 x 10(9)/l were 24 and 20 days respectively. Severe toxicity included infections in 20 patients (59%), bleeding in two (6%), cardiac anomalies in two (6%), and vomiting in one (3%). Overall four patients (12%) died from chemotherapy related toxicity and 21 (62%) had resistant disease. Median overall survival was 4 months and median disease-free survival 8 months. We conclude that this regimen had efficacy with reduced toxicity in relapsed patients. Higher dosages for the same drugs could be tolerated by better risk patients for precise evaluation of cross reactivity with cytarabine-based regimens.

Phase II study of YNK01 (1-beta-D-arabinofuranosylcytosine-5'-stearylphosphate), a derivative of cytosine arabinoside, on hematological malignancies was conducted by multi-institutional cooperative group. YNK01 was administered orally at dose of 100-300 mg/body/day for more than 2 weeks. The number of registered and evaluated patients were 211 and 156, respectively. Of 23 patients with acute myelogeneous leukemia (AML), 2 complete response (CR), one partial response (PR) were observed (CR + PR: 13.0%). Hypoplastic leukemia (1/4: 25%), acute unclassified leukemia (1/1: 100%). Of 45 patients with MDS, 2CRs, 6 good response (GR) and 5PRs were observed (CR + PR: 28.9%). AML developing after a prior history of MDS (5/17: 29.4%), CML-BC (2/9: 22.2%). Of 19 patients with CML, 9 achieved CR, 3 achieved PR (63.2%). Of 11 patients with polycythemia vera, 4 achieved CR, 5 achieved PR (81.8%). Of 6 patients with essential thrombocytosis, 2 achieved CR, one achieved PR (50%). The major adverse effects included gastrointestinal toxicities such as nausea, vomiting, anorexia, diarrhea, and elevation of GOT and GPT which were tolerable and reversible. This study indicates that YNK01 is a useful agent against acute leukemia and MDS, especially RAEB, RAEB in T, CMMoL.

As part of a broad phase I study of recombinant human granulocyte-macrophage colony-stimulating factor (rh GM-CSF), four patients were treated who had myelodysplastic syndrome (MDS) with excess blasts. The GM-CSF was given daily as an intravenous injection over a period of 30 min for 5 days. A total of 11 cycles were conducted. Each patient received at least two different dose levels. In three patients, three different dosages were delivered. The treatment course was interrupted by a 10-day rest period. Rh GM-CSF was well tolerated, with only minor side effects seen, which included bone discomfort at the lower back, sternum and ribs, and constitutional symptoms such as low grade fever, nausea/vomiting, and mild myalgias. Whereas no increases in platelet and reticulocyte counts were recorded, elevations of absolute neutrophil counts above 100 cells/microliters occurred in all patients. The most striking finding was, however, the development of increases in the number of circulating and bone marrow blast counts that were observed particularly when doses of greater than or equal to 500 micrograms/m2 of body surface area were administered. In line with data demonstrating in vitro induction of proliferation of leukemic blast cells by rh GM-CSF, one may take advantage of blastogenesis induced in vivo that may favor the use of a therapeutic strategy by recruiting quiescent cells into the mitotic cycle which would then represent optimum targets for a subsequent cycle-specific cytotoxic chemotherapy. Such an approach could form the basis for new clinical trials in MDS.

A phase II clinical trial on MDS was conducted in a cooperative study with orally administrable ara-C analogue, PLAC, which is resistant to cytidine deaminase and had shown an anti-tumor activity on various experimental tumors by oral route. Fifty MDS (3 RA, 18 RAEB, 11 RAEB-T, 18 RAEB-blast crisis (BC) were treated orally with 100 to 400mg/body of daily PLAC. One good response (GR) and 3 partial responses (PR) were obtained in 18 RAEB, and 2 complete remissions, 1 GR and 1 PR were noted in 11 RAEB-T, while 3 PR were seen in 18 RAEB-BC. Overall CR rates were 4%, GR rates 4% and PR rates 14%. Thus, 22% of MDS responded to oral PLAC. No clear daily dose-response was noted. Response, however, was dependent on the treatment period and was obtained in cases which had been treated for more than 20 days. Besides myelosuppression, side effects were mainly gastrointestinal, and anorexia (32%), nausea/vomiting (30%) and diarrhea (8%) were observed. Oral PLAC seems to be active on MDS which does not necessarily require admission to hospital.

A 10-year-old girl with a lumbosacral myelomeningocele, managed with clean intermittent catheterization, presented with headache, vomiting, and lethargy. The cerebrospinal fluid (CSF) and urine cultures revealed Escherichia coli, documented to be the same subtype. The organisms were subtyped and the E. coli from both the urine and CSF were noted to be of the same strain. Management consisted of intravenous antibiotics and ultimate replacement of the ventriculoperitoneal shunt. Children with myelodysplasia and CSF shunts should be carefully monitored in a multidisciplinary fashion to anticipate, correctly diagnose, and treat CSF shunt infections associated with bacteriuria.

FK506 (Tacrolimus) is an immunosuppressive drug that blocks the activation of antigen-specific T lymphocytes, a major component in the pathogenesis of graft-versus-host disease (GVHD). This study was designed to obtain first estimates of the safety and efficacy of FK506 monotherapy in the prevention of GVHD following HLA-identical sibling marrow transplantation. Additionally, a subset of patients was studied to define the pharmacokinetic profile of FK506. Twenty-seven adult patients with leukemia or myelodysplasia received FK506 starting the day before transplant at a dose of 0.04 mg/kg/d by continuous intravenous infusion. When clinically possible, FK506 was given orally in two divided doses starting at five times the daily intravenous dose. FK506 doses were adjusted to target a steady state or trough blood level between 10 to 30 ng/mL. These patients were followed for 6 months posttransplant. All patients had sustained marrow engraftment. Frequently noted adverse events included reversible renal dysfunction, diarrhea, fever, nausea, vomiting, and headache. Most patients required FK506 dose reductions associated with elevated serum creatinine. Two (7%) patients relapsed, one of whom died of the disease within the 6-month study period. A second patient died due to pulmonary mucor. Whole blood pharmacokinetic parameters indicated a half-life of 18.2 +/- 12.1 hours; volume of distribution of 1.67 +/- 1.02 L/kg; clearance of 71 +/- 34 mL/h/kg; and bioavailability of 32 +/- 24%. Eleven of 27 (41%) patients developed grade II to IV acute GVHD, including 10 grade II and one grade III. Six of 24 (25%) evaluable patients developed chronic GVHD. These data indicate that FK506 monotherapy has activity in preventing GVHD. Further studies of FK506 with lower doses to improve tolerability and in combination with other immunosuppressants to augment efficacy are warranted.

A phase III prospective randomized multicenter study was performed to determine whether quinine could improve the response rate of poor-risk acute leukemias (ALs) to standard chemotherapy including a multidrug resistance (MDR)-related cytotoxic agent. The rationale of the study was based on the negative prognostic value of MDR phenotype in ALs and the ability of quinine to reverse this phenotype both in vitro and ex vivo. Three hundred fifteen patients (median age, 49 years; range, 16 to 65) with relapsed (n = 108) or refractory (n = 32) acute myeloblastic leukemia (AML), relapsed (n = 27) or refractory (n = 9) acute lymphoblastic leukemia (ALL), secondary AL (n = 22) or blastic transformation of myelodysplastic syndrome ([MDS] n = 74) or myeloproliferative syndrome ([MPS] n = 43) were randomly assigned to receive mitoxantrone ([MXN] 12 mg/m2/d, days 2 to 5) and cytarabine ([Ara-C] 1 g/m2/12 h, days 1 to 5) alone or in combination with quinine (30 mg/kg/d, days 1 to 5; continuous intravenous infusion beginning 24 hours before MXN infusion). Side effects of quinine were observed in 56 of 161 quinine-treated patients and disappeared in all but four cases after one or two 20% dose decreases. Sera from quinine-treated patients showed increased MXN uptake in an MDR-positive cell line compared with matched sera obtained before quinine infusion. Quinine induced a significant increase in the incidence of nausea, vomiting, mucositis, and cardiac toxicity. A complete response (CR) was observed in 85 of 161 patients (52.8%) from the quinine-treated group versus 70 of 154 patients (45.5%) in the control group (P = .19). The most important differences between quinine and control group CR rates were observed in patients with refractory AMLs and blastic transformation of MDS and MPS. The CR rate was higher in P-glycoprotein-positive cases, although the difference was not significant. Failure of the regimen due to blastic persistence or blast number increase was higher in the control group (61 of 154 patients) than in the quinine group (45 of 161, P = .04). Early death was observed in eight cases (four in each arm) and death in aplasia in 27 cases (20 in quinine group v seven in control group, P = .01). The significant increase of toxicity in the quinine arm could have masked the clinical benefit of MDR reversion in poor-risk ALs.

We have retrospectively reviewed the ability to safely deliver total body irradiation (TBI) in the outpatient setting in 10 pediatric patients undergoing stem cell transplantation. Patients had a median age of 14 years (range 9-17 years) with diagnoses that included ALL in second remission, AML in second remission, myelodysplastic syndrome, Ewing's sarcoma, and rhabdomyosarcoma. Patients received a total of 1375 cGy or 1440 cGy given in a hyperfractionated schedule (11 or 12 fractions) over a 4-day period. All children were seen in the outpatient clinic daily during TBI and all were housed within a 20 mile radius of our institution during this period. Eight patients achieved good control of nausea and emesis with ondansetron alone while two patients required ondansetron and diphenhydramine. Nine patients received some form of intravenous hydration during this period (hyperalimentation, fluid boluses in clinic, or night-time intravenous fluids). One patient maintained good hydration with oral intake alone. Only one child required admission during this period for persistent nausea and vomiting despite antiemetics and intravenous fluids. A cost approximation suggests that TBI delivered in the outpatient setting resulted in a saving of approximately $2400 per patient. We conclude that TBI administered to children and adolescents in the outpatient setting can be a safe and cost-effective practice.

The aminothiol, amifostine (Ethyol; U.S. Bioscience, West Conshohocken, PA), is a cytoprotective agent that ameliorates the toxicities of anticancer therapy. In vitro, amifostine promotes the formation and survival of primitive hematopoietic progenitors derived from myelodysplastic bone marrow (BM) specimens. To evaluate the hematological effects of amifostine, 18 patients with myelodysplastic syndrome (MDS) and one or more refractory cytopenias received treatment with amifostine in a Phase I/II study. Four cohorts received intravenous treatment with 100, 200, or 400 mg/m2 amifostine three times a week, or 740 mg/m2 weekly for three consecutive weeks followed by 2 weeks observation. Nonresponding patients received a second course of therapy at the next higher dose level depending upon drug tolerance. Bone marrow (BM) progenitor growth was assessed before treatment and after day 21. Diagnoses included refractory anemia (7), refractory anemia with ringed sideroblasts (5), refractory anemia with excess blasts (RAEB) (4), and RAEB-in transformation (RAEB-t) (2). Single- or multi-lineage hematologic responses occurred in 15 patients (83%) treated with the three-times-a-week dose schedule. Fourteen patients had a 50% or greater increase in absolute neutrophil count with amifostine treatment (range, 426 to 11,348/microL). Platelet count increased in 6 (43%) of 14 patients with thrombocytopenia (absolute increase, 16, 000 to 110,000/microL), and 5 of 15 red blood cell transfusion-dependent patients had a 50% of greater reduction in transfusion needs. Assayable hematopoietic progenitors increased in 13 of 15 evaluable patients; including CFU-GEMM (12), BFU-E (8), and CFU-GM (6). Amifostine doses less than or equal to 200 mg/m2 were well tolerated, whereas grade II nausea, vomiting, and fatigue was limiting at higher doses. Three patients with excess blasts before enrollment experienced an increase in BM blast percentage and two patients had evolution to acute leukemia that persisted after treatment withdrawal. We conclude that amifostine administered at doses </=200 mg/m2 three times a week is well tolerated and has hematologic activity in patients with MDS.

Patients who have metastatic breast cancer are seldom curable. Chemotherapy given by conventional doses and schedules generally produces complete remissions in 10% to 20% of patients. This study sought to determine 1) whether a combination of dibromodulcitol, Adriamycin, vincristine, tamoxifen, Halotestin, and methotrexate with leucovorin rescue (DAVTHML) can produce a complete remission rate of 50%; and 2) the toxicity of this combination in patients with chemotherapy-naive metastatic breast cancer. Patients were treated with six 28-day cycles of DAVTHML induction chemotherapy consisting of dibromodulcitol, 135 mg/m2 perorally days 1 to 10; Adriamycin 45 mg/m2 intravenously day 1; vincristine, 2 mg intravenously day 1; tamoxifen and Halotestin, 20 mg perorally daily; methotrexate, 800 mg/m2 intravenously days 15 and 22; and leucovorin, 15 mg/m2 perorally every 6 hours for 9 doses, starting 4 hours after methotrexate. After induction, patients who had stable disease or a partial response were treated with a cyclophosphamide, methotrexate, and 5-fluorouracil-based regimen (CMF). Patients in complete remission were treated with three additional cycles of DAVTHML after achieving complete remission and then observed off therapy until relapse, when DAVTHML was to be given again. Fifty-eight patients were included in this study. During induction, 26% of eligible patients experienced a complete remission; overall response rate was 80%. The median time to treatment failure and the median survival time of eligible patients was 11.1 and 24.0 months, respectively. This did not change significantly when all the patients were included in the evaluation. The 3-year and 5-year survival rates were 37% and 11%, respectively. Ninety percent of the eligible patients experienced grade III or IV toxicity. They were leukopenia (75%), anemia (20%), thrombocytopenia (20%), and vomiting (17%). No lethal toxicity was documented during therapy; however, 1 patient later died of myelodysplastic syndrome induced by dibromodulcitol. The overall response and complete remission rates from our study were encouraging. The toxicity of DAVTHML was tolerable, with the exception of myelodysplastic syndrome from dibromodulcitol. The concept of using mid-cycle nonmyelosuppressant agents to increase complete remission rate is feasible.
