Abstract
BACKGROUND Despite modern treatment programs, less than 20% of adult cases of acute lymphoblastic leukemia (ALL) are cured. For relapsing and/or refractory patients, use of high dose cytosine arabinoside (ara-C) and anthracyclin achieved a complete remission (CR) rate of up to a 75%. The aim of this study was to evaluate in adult patients with ALL 1) the CR rate of a chemotherapy schedule similar to a schedule for acute myeloblastic leukemia (AML) patients, 2) the antileukemic value and the tolerance of 3 intensive stage treatments, and 3) the impact of recombinant granulocyte-macrophage-colony stimulating factor (rGM-CSF) on chemotherapy-induced neutropenia and infectious complications, as well as the effect of dose intensity. METHODS Between November 1990 and April 1992, 67 patients ages 15-55 years with de novo ALL were randomly assigned to receive either rGM-CSF or placebo. The induction treatment consisted of idarubicin, methylprednisolone, and high dose ara-C. After achieving CR, patients up to age 45 years who had an HLA-identical sibling were assigned to undergo allogeneic bone marrow transplantation (BMT). All remaining patients received a first course of early intensification with high dose ara-C, mitoxantrone, etoposide, and methylprednisolone, followed by autologous, unpurged BMT. RESULTS Of the 64 eligible patients, 50 (78%) achieved CR. Sixteen allogeneic and 18 autologous BMTs were performed. The median survival was 10.2 months. The 4-year survival was 24%. rGM-CSF only improved the incidence of severe mucositis during the induction course (P = 0.003) and probably also improved the median duration of fever (P = 0.07). CONCLUSIONS This schedule, similar to that for the treatment of AML patients, with early BMT included, did not prove to be a satisfactory approach to the treatment of most adult ALL patients, although CR was achieved in 78% of cases. In this study, no major improvement was obtained with rGM-CSF therapy.

Abstract
Autologous bone marrow transplantation can induce long-term LFS in 20% to 40% of patients with relapsed acute leukemia and should be considered as salvage therapy for patients who lack an HLA-matched donor and for patients over 45. Adult ALL patients and children with ALL in extramedullary relapse beyond second CR should receive alloBMT if at all possible. The role of ABMT in acute leukemia patients in first CR remains unclear despite randomized trials (Table 2). Because protocol deviations, early relapse, and inappropriately high treatment-related mortality unequally affected the ABMT cohort, and because recent randomized trials have used old purging methodologies, it is not possible to conclude that ABMT is not beneficial. More recent studies show that most patients are able to proceed with the intended ABMT and that modern purging may be associated with a treatment-related mortality rate of less then 5%. Immunomodulation and graft engineering uniquely suited to autologous progenitor cells indicate that ABMT should continue to be studied in the management of acute leukemia.

Abstract
BACKGROUND Small patient numbers and short follow-up are common in some acute myeloid leukaemia (AML) studies and data on secondary malignancies after treatment of AML are rare. AIMS To determine the prognostic factors and long-term treatment results. METHODS A retrospective study of patients with de novo AML under the age of 60 over a 20-year period in which two induction therapy regimens: 7:3 (1975-1983) and 7:3:7 (1984-1996) and three consolidation chemotherapy regimens: 5:2 (1975-1983), 5:2:5 (1984-1990) and Ara-C/mitoxantrone (1991-1996) were used. Disease-free (DFS), overall survivals (OS) and prognostic factors were analysed. RESULTS Two-hundred and two of 276 (73%) patients attained complete remission (CR). The CR rates of 7:3 and 7:3:7 regimens were 70.5% and 74.5% respectively (p=0.92). The median DFS was 12 months and the projected DFS at 10- and 20-years were 23% and 21% respectively. For patients consolidated with 5:2, 5:2:5 and Ara-C/mitoxantrone, the median DFS was 15 m, 12 m and 11 m respectively and the projected ten-year DFS were 27%, 21% and 18% respectively (p=0.2). Ninety per cent of relapses occurred within two years from remission but there were two late relapses at 109 m and 120 m respectively. Young age and FAB M3 subtype were favourable prognostic factors to OS (p=0.04) and DFS (p=0.006) respectively. There was no secondary solid tumour in the long-term survivors. CONCLUSION Our experience confirmed the efficacy of standard-dose Ara-C/daunorubicin and the prognostic value of age and FAB subtype. Median and projected DFS were similar to western studies.

Abstract
In the AML 8A study patients were treated with remission-induction therapy followed by one consolidation course. Patients in complete remission (CR) were randomised between autologous bone marrow transplantation (ABMT) and a second intensive consolidation course, except for those with a histocompatible sibling donor, who received allogeneic bone marrow transplantation (alloBMT). This analysis was performed to determine whether centres which only performed induction and consolidation therapy, achieved similar results as centres who also performed transplantation. 542/676 (80%) from transplantation centres and 150/194 (77%) from referring centres achieved CR, with an early death rate of 5% and 11%, respectively (P = 0.01). 66% of patients with a donor from transplantation centres received alloBMT in first CR compared with 57% from referring centres (P = 0.2). Transplantation centres randomised 64% of patients without a donor, referring centres 47% (P = 0.04). The full protocol treatment was completed by 275/542 (51%) and 61/150 (41%) patients, respectively (P = 0.04). The overall survival rate at 6 years from diagnosis was 34% and 36%, respectively (P = 0.9). In conclusion, the type of centre did not appear to have an influence on overall survival. The feasibility of the study was acceptable for both types of centres. The referring centres applied more selection for transplantation. Despite a more intensive second-line treatment at transplantation centres, the overall outcome remained similar to that of referring centres.

Abstract
The failure of convenional chemotherapy in relapsed or refractory and other poor risk AML patients has been linked to expression of the multidrug resistance gene (mdr 1) product P-glycoprotein (P-gp). PSC 833 is a non-competitive inhibitor of P-gp and has been shown in vitro and in vivo to restore sensitivity of resistant tumor cells to anticancer drugs (ACDs). Induction chemotherapy consisting of cytarabine (C) in combination with PSC 833 and escalating doses of mitoxantrone (M) and etoposide (E) over 5 or 6 days were tested in two phase I/II studies in poor prognosis AML. Overall, 59 patients were evaluated: their age ranged between 18 and 70 years. Fourteen patients had primary refractory disease, 25 had relapsed within 9 months from first complete remission (CR), 5 were in second relapse, 10 had secondary AML, and 4 had relapsed post-bone marrow transplantation. PSC 833 was given as a constant i.v. infusion at a rate of 10 mg/kg/24 h for 5 or 6 days, depending on the duration of chemotherapy. In both studies a loading dose of 2 mg/kg of PSC 833 was given on day 1. In the 5-day regimen, the final study doses of the cytotoxic agents were C 1 g/m2/d, M 4.0 mg/m2/d, and E 40 mg/m2/d. In the 6-day regimen, the final study doses of the cytotoxic agents were C 1 g/m2/d, M 4.5 mg/m2/d and E 30 mg/m2/d. The combined efficacy results of both studies indicate that PSC-MEC is active in all treatment indications, complete remission being achieved in 2/5 (40%) second relapses, 8/25 (32%) early relapses, 3/10 (30%) secondary AML, 3/15 (20%) refractory patients and 1/4 (25%) post-BMT relapses. Based on historical controls, this observed overall CR rate (29%) is higher than expected in this high risk patient population. Our data indicate that, in refractory/relapsed AML patients, PSC-MEC regimens had encouraging antileukemic effects, is well tolerated, and has led to Phase III trials in this setting.

Abstract
PURPOSE The Cancer and Leukemia Group B conducted parallel phase I trials of cytarabine, daunorubicin, and etoposide (ADE) with or without PSC-833 (P), a modulator of p-glycoprotein-mediated multidrug resistance. PATIENTS AND METHODS One hundred ten newly diagnosed patients > or = 60 years of age with de novo acute myeloid leukemia (AML) were treated. All patients received cytarabine by continuous infusion for 7 days at 100 mg/m(2)/d. The starting dose of daunorubicin was 30 mg/m(2)/d for 3 days. Etoposide was administered at a dose of 100 mg/m(2)/d for 3 days, except in the last cohort administered ADEP, who received 60 mg/m(2). PSC-833 was given intravenously with a loading dose of 1.5 mg/kg over 2 hours and a simultaneous continuous infusion of 10 mg/kg/d continued until 24 hours after the last dose of daunorubicin or etoposide. RESULTS There was no toxicity attributed to the PSC-833. Dose-limiting toxicity was primarily gastrointestinal (diarrhea, mucositis in the ADEP group). The estimated maximum-tolerated doses, calculated using a logistic regression model, were daunorubicin 40 mg/m(2)/d for 3 days with etoposide 60 mg/m(2) for 3 days in the ADEP group and daunorubicin 60 mg/m(2)/d for 3 days and etoposide 100 mg/m(2)/d for 3 days in the ADE group. Twenty-one (48%) of 44 patients achieved complete remission with ADE, compared with 29 (44%) of 66 patients treated with ADEP. CONCLUSION It is necessary to decrease the doses of daunorubicin and etoposide when they are administered with PSC-833, presumably because of the effect of the modulator on the pharmacokinetics of these agents. A phase III trial comparing the regimens derived from this phase I trial has recently begun.

Abstract
BACKGROUND High-dose chemotherapy (HDCT) with stem cell rescue is increasingly being used as a salvage or consolidation therapy for patients with a variety of malignant diseases. The authors give an overview of the current role of HDCT in lympho-hematopoietic malignancies and solid tumors. METHODS The use of allogenic or autologous hematopoietic stem cells allows an increase of the dose of chemotherapeutic drugs by a factor of between 4- and 30-fold compared to conventional chemotherapy protocols. In recent years mobilized peripheral blood stem cells (PBSC) have largely replaced the use of autologous bone marrow due to more rapid hematopoietic reconstitution and are increasingly used in the allogenic setting. This article reviews the data of high-dose chemotherapy in non-Hodgkin's lymphoma, Hodgkin's lymphoma, multiple myeloma, acute leukemias, chronic myelogenous leukemia, chronic lymphatic leukemia, myelodysplastic syndrome, breast cancer, ovarian cancer, germ cell cancer, and lung cancer. Current clinical trials further evaluating the role of HDCT are described. RESULTS Data on results of HDCT are available for a variety of malignancies showing the feasibility and efficacy of the procedure with tolerable toxicity. Although numerous clinical trials of HDCT have been performed, only few randomized trials have demonstrated that such strategies are statistically significantly better than conventional forms of therapy. CONCLUSION HDCT has been shown to be useful in the treatment of certain patients with lymphomas, leukemias, myeloma, breast cancer, and testicular cancer. Most of these findings still have to be confirmed by randomized clinical trials. Therefore, HDCT should only be given in controlled studies and at suitable centers.

Abstract
Fazarabine has demonstrated a broad spectrum of antitumor activity in experimental models including P388 and L1210 cell lines. Previous phase I clinical trials using a 3-day continuous infusion schedule of Fazarabine have shown myelosuppression to be the dose limiting toxicity in solid tumors. Based on this clinical and preclinical experience we designed a phase I study to determine the toxicity, maximum tolerated dose (MTD), and antileukemic efficacy of Fazarabine using a 3-day continuous infusion schedule in patients with refractory or relapsed acute leukemia or chronic myelogenous (CML) in blastic phase. Adults with a diagnosis of acute leukemia or blastic phase CML who were refractory or had relapsed on salvage chemotherapy were entered on study. Fazarabine was administered as a continuous infusion over 3 days every 3 to 4 weeks. The initial dose was 2 mg/m2/hour x 72 hours. Results showed that the MTD was 425 mg/m2/hour infused over 72 hours every 3 to 4 weeks. At this dose level neurotoxicity and fluid overload were the dose limiting toxicities. Among 71 patients treated, we observed one complete remission, one partial remission and one hematologic improvement. No obvious dose response relationship could be determined. In conclusion, Fazarabine has not shown a beneficial effect in the therapy of acute leukemia. Since 71 patients and 20 dose levels were required to determine the MTD of Fazarabine, a reassessment of our phase I study designs should be considered to provide patients with better potential toxic: therapeutic benefits in such trials.

Abstract
To determine the safety and efficacy of the combination of idarubicin, cytarabine and etoposide ("ICE") for induction and consolidation treatment of acute myeloid leukemia (AML), and of dose-intensification of cytarabine in this setting, 54 previously untreated patients in three cohorts were studied by sequential dose escalation of cytarabine, in combination with standard doses of idarubicin and etoposide. Cytarabine was given to Cohort 1 at the conventional dosage of 100 mg/m2 per day by continuous infusion for 7 days in induction and 5 days in consolidation; to Cohort 2 at high-dose (HiDAC) (3 g/m2 intravenously twice daily on days 1, 3, 5 and 7) during induction with conventional dosage during consolidation; to Cohort 3 HiDAC was given for both induction and consolidation. In addition, Cohort 3 patients received lenograstim (Granocyte; rHuG-CSF) after both induction and consolidation courses. We found that there was no significant difference between the three cohorts in hematological toxicity in induction, but that HiDAC was associated with a greater incidence of gastro-intestinal toxicities. There was no difference in induction mortality between the three cohorts, which was 11% overall. Consolidation with HiDAC led to a significant increase in hematological toxicity. Overall, the complete remission (CR) rate was 80% with no significant difference between the three regimens. The estimated disease free survival at 3 years was 28%, 67% and 54% respectively for Cohorts 1, 2 and 3 with an estimated overall survival of 38%, 63% and 47%. We conclude that cytarabine dosage can be escalated safely in combination with idarubicin and etoposide in both induction and consolidation. The combination is effective for induction treatment of AML and its side-effects appear similar to those of standard regimens. Whether its use offers long-term benefits compared with standard regimens is the subject of ongoing controlled randomized studies.

Abstract
Generation of cellular immune responses against acute myelogenous leukemia (AML) blasts is a possible therapeutic approach in leukemia therapy. However, when using native AML blasts as stimulator cells during ex vivo generation of leukemia-reactive T cells, one has to ensure that the T cell population is not contaminated with proliferating AML blasts. Our results demonstrate that gamma-irradiation could be used to stop AML blast proliferation for all patients investigated. However, gamma-irradiation also caused a dose-dependent reduction in the constitutive AML blast secretion of the potentially T cell stimulatory cytokines IL-1beta, IL-6, and tumor necrosis factor-alpha (TNF-alpha). At the same time, gamma-irradiation resulted in a dose-dependent decrease in anti-CD3-stimulated proliferative responses of T cell clones in the presence of AML blast accessory cells. When using 50 Gy irradiation, however, AML blast expansion was avoided, and anti-CD3 and PHA-stimulated T cell proliferation was detected in the presence of accessory AML blasts for most AML/T cell combinations investigated. When AML blasts were cultured with GM-CSF + IL-4 to develop a dendritic cell phenotype, enhanced T cell proliferation in the presence of in vitro precultured AML blasts was observed for most patients even after 50 Gy irradiation. We conclude that when using native AML blasts as accessory cells during in vitro generation of leukemia-reactive T cells, an irradiation dose of 50 Gy can be used for a majority of AML patients to avoid the risk of leukemia cell expansion during culture and with the maintenance of AML blast accessory cell function. However, when in vitro expanded cells are used in clinical trials, this antiproliferative effect should be documented with appropriate in vitro testing for every patient so that the possibility of decreased sensitivity to gamma-irradiation in exceptional patients is excluded.

Abstract
We developed a fusion toxin consisting of the catalytic and translocation domains of diphtheria toxin linked to human granulocyte-macrophage colony-stimulating factor (GM-CSF) (DTGM) for the treatment of patients with acute myeloid leukemia (AML). Our goal in this study was to determine the toxicity and pharmacokinetics of DTGM in cynomolgus monkeys (Macacca fascicularis), which possess cross-reactive GM-CSF receptors. Four groups of young adult monkeys (6 males and 12 females) were treated with five daily bolus iv infusions of 1, 5, 7.5, and 10 microgram/kg DTGM. Monkeys (2 males and 2 females) treated at 1 microgram/kg/day showed no significant side effects. Monkeys (2 males and 2 females) treated at 5 microgram/kg/day showed Grade 1-2 thrombopenia (NCI common toxicity criteria) on day 9. In contrast, monkeys (6 females) treated at 7.5 microgram/kg/day developed Grade 3 neutropenia, Grade 1-2 thrombopenia, Grade 1-3 anemia, and Grade 1-3 hypoalbuminemia. The neutropenia developed by day 4 in the 7.5 microgram/kg/day monkeys and by day 3 or 5 in the 10 microgram/kg/day monkeys and resolved in both groups by day 9, but the thrombopenia, anemia, and hypoalbuminemia persisted until day 16. Monkeys (2 male and 2 female) treated with 10 microgram/kg/day showed Grade 4 neutropenia that resolved by day 8 and Grade 2-3 anemia, hypoalbuminemia, and thrombopenia. Three of the animals developed sepsis. DTGM plasma half-life was 30 min with a peak concentration of 0.1 microgram/mL or 2 nM (1000-fold higher than the IC50 in vitro for AML blasts). Immune responses were minimal in all animals tested at 14 and 28 days with anti-DTGM levels <1 microgram/mL. All four animals at 10 microgram/kg died or were euthanized, and necropsies were performed. Animals necropsied on days 4 and 6 showed marked apoptosis and hypoplasia in the marrow, which was completely resolved for animals necropsied on day 9. No injury to other organs, including kidney, heart, liver, central nervous system, or lung, was seen. The drug was selectively toxic to malignant or differentiated myeloid cells with little toxicity to myeloid progenitors or other organs. Minimal effects in nontarget tissues make DTGM a promising candidate chemotherapeutic agent.

For younger patients with acute myeloid leukemia, the current priority is to prevent disease relapse. Intensification of induction has been shown to achieve this. Several randomized trials have been conducted to evaluate the role of autografting in acute myeloid leukemia. All trials reduce the risk of relapse but do not necessarily improve the survival, either because the competing effects of procedural mortality or salvage after relapse balance the benefits. Patients with different risk profiles may have different treatment plans. In older patients, progress is difficult to detect. Overcoming inherent drug resistance is of current interest, while improving supportive care by the routine use of growth factors has been disappointing.

Abstract
Patients with acute myelogenous leukemia secondary to an antecedent hematologic disturbance or cytotoxic chemotherapy are considered to have a very low likelihood of leukemia-free survival regardless of the form of post-remission therapy. The purpose of this study is to evaluate, on the basis of intention to treat, the feasibility and efficacy of high-dose cytarabine/anthracycline consolidation chemotherapy followed by autologous transplantation of chemotherapy/rHuG-CSF-mobilized peripheral blood progenitor cells for seventeen adult patients (median age 63, range 27 to 68) with secondary acute myelogenous leukemia in first remission. Ten eligible patients underwent autologous transplantation of peripheral blood progenitor cells procured following high-dose cytarabine/mitoxantrone consolidation chemotherapy used as a method of in vivo purging. A median of 5 collections (range 2 to 13) were required to procure a median of 9.27 x 10(8) total mononuclear cells/kg (range 2.35 to 21.44 x 10(8) per kg). The median number of CD34-positive progenitor cells was 1.18 x 10(6) kg (range 0.34 to 30.9 x 10(6) kg). After preparative conditioning with 11.25 Gy total body radiation and cyclophosphamide (120 mg/kg) and autologous transplantation, the median time to neutrophil and platelet recovery were 18 days (range 12 to 29 days) and 25 days (range 8 to 158+ days), respectively. After a median follow-up for surviving patients of 33.4 months (range 7.5 to 54 months), 9 of 17 patients (53%) remain alive with 7 in continued first remission. The median remission duration is 13 months (3 to 53 months) and actuarial leukemia-free survival at 3 years is 51+/-25%. Toxicity of autologous peripheral blood progenitor cell transplant included serious liver and pulmonary toxicity in 2 and 1 patient, respectively. Our results demonstrate that a postremission program of high-dose cytarabine-based consolidation chemotherapy followed by autologous transplantation of chemotherapy-mobilized peripheral blood progenitor cells is feasible for patients with secondary acute myelogenous leukemia producing prolonged leukemia-free survival with minimal toxicity.

Abstract
Adult acute myeloid leukaemia (AML) is uncommon, with an age-standardised incidence of approximately 3 per 100,000. Patients present (median age, > 60 years) with evidence of bone marrow failure, anaemia, leukopenia or thrombocytopenia and their sequelae, or AML is detected incidentally by a full blood count. Treatment for AML aims to eliminate leukaemia from bone marrow with intensive chemotherapy: age (over or under 60 years) and performance status determines whether standard or high-dose chemotherapy can be used, but fewer than half the patients with AML are under 60 years. Supportive therapy during initial induction chemotherapy is needed to control neutropenic sepsis and thrombocytopenic bleeding, and to ameliorate the side effects of chemotherapy. Standard induction chemotherapy produces complete remission in 56%-74% of patients; 20% are long term survivors; 10%-15% of patients die in the induction period. Allogeneic haemopoietic stem cell transplantation is recommended in patients under 50 years with an HLA- compatible sibling, with the best outcomes achieved in patients transplanted in first complete remission. It can also provide long term survival in patients who fail to achieve remission after induction therapy. The outcome of AML has improved, particularly for younger patients, but treatment outcomes for older patients and those with secondary leukaemia are still unsatisfactory. The mean overall survival of patients in randomised studies treated with standard therapy is still only 9-15 months.

Abstract
BACKGROUND In young adults with acute myeloid leukemia, intensive chemotherapy during the initial remission improves the long-term outcome, but the role of bone marrow transplantation is uncertain. We compared high-dose cytarabine with autologous or allogeneic marrow transplantation during the first remission of acute myeloid leukemia. METHODS Previously untreated adolescents and adults 16 to 55 years of age who had acute myeloid leukemia received standard induction chemotherapy. After complete remission had been achieved, idarubicin (two days) and cytarabine (five days) were administered. Patients with histocompatible siblings were offered allogeneic marrow transplantation, whereas the remaining patients were randomly assigned to receive a single course of high-dose cytarabine or transplantation of autologous marrow treated with perfosfamide (4-hydroperoxycyclophosphamide). Oral busulfan and intravenous cyclophosphamide were used as preparative regimens for both allogeneic and autologous marrow transplantation. The end points were survival from the time of complete remission and disease-free survival. RESULTS In an intention-to-treat analysis, we found no significant differences in disease-free survival among patients receiving high-dose chemotherapy, those undergoing autologous bone marrow transplantation, and those undergoing allogeneic marrow transplantation. The median follow-up was four years. Survival after complete remission was somewhat better after chemotherapy than after autologous marrow transplantation (P=0.05). There was a marginal advantage in terms of overall survival with chemotherapy as compared with allogeneic marrow transplantation (P=0.04). CONCLUSIONS A postinduction course of high-dose cytarabine can provide equivalent disease-free survival and somewhat better overall survival than autologous marrow transplantation in adults with acute myeloid leukemia.

Abstract
Thrombocytopenia is a major cause of morbidity following intensive chemotherapy for acute leukemia. Over recent years, there has been an increasing use of platelet transfusions which, although generally efficacious to prevent severe hemorrhage, have associated risks of transmitting blood-borne disease and of alloimmunization. Therefore, there is a clinical requirement for a drug that will reliably alleviate the thrombocytopenia associated with leukemia therapy. The c-mpl ligand thrombopoietin is the most interesting factor for the treatment of thrombocytopenia because of its lineage specificity. Phase I and II studies confirm its biological efficacy to induce rise in platelet count in patients with solid tumors and acute leukemia. Several other pleiotropic hematopoietic growth factors are also currently in clinical trials. These include interleukin-6, interleukin-3, interleukin-11, PIXY321 and stem cell factor. The effects of these cytokines appear to be modest at most and, with the exception of interleukin-11, their side effects are likely to limit their clinical application. Combinations of factors may prove more efficacious approaches to enhance platelet recovery.

Abstract
Gene transfer of the cytidine deaminase (CDD) cDNA has recently been shown to induce cellular resistance to cytarabine (AraC) in vitro. To investigate the role for CDD in acute myeloid leukaemia (AML) we analysed the CDD activity and CDD gene structure in blast material from well-defined patients with untreated and AraC refractory (RF) AML. Median CDD activity in previously untreated AML was significantly lower than in RF-AML blasts (P=0.015) and was significantly lower in patients with complete remission than with blast persistence following induction chemotherapy (P=0.043). Structural investigation of the CDD gene by Southern analyses and RT-PCR showed no detectable aberrations. Sequence analysis of the CDD cDNA from nine RF-AML patients showed inconsistent aberrations in three patients. Semiquantitative assessment of CDD mRNA expression revealed a significant correlation with CDD activity. In conclusion, concordant with another recent study our data suggest a correlation of pretherapeutic CDD activity with induction treatment response. Besides the previously described prognostic impact of mdrl expression, this result could be useful for the development of risk-adapted AML treatment strategies and warrants further studies of CDD activity in well-defined cohorts of AML patients and of the mechanisms involved in the regulation of CDD activity.

Abstract
Abstract
High plasma levels of the shed form of L-selectin (sL-selectin) are frequently detectable in acute myeloid leukemia (AML). sL-selectin can inhibit blast cell adhesion to vascular endothelium and may thereby influence the phenotype of AML. In this study, we have investigated the relationship between sL-selectin levels and clinical presentation or disease outcome in 100 patients with AML. Fifty-eight patients were found to have sL-selectin levels ≥3.12 μg/mL (≥3 SD above the mean of healthy controls: “increased”). Patients with extramedullary disease such as lymphadenopathies, splenomegaly, hepatomegaly, and/or muco-cutaneous infiltration had significantly increased sL-selectin levels (P < .001). sL-selectin levels were significantly heterogeneous in the French-American-British subtypes (P = .0003). Patients with “normal” sL-selectin levels had higher probability of achieving complete remission (CR) than with “increased” levels: 81% versus 64%, respectively (P = .06). When adjusting for clinically relevant covariates predictive for CR (sex, age, Auer rods), “normal” sL-selectin levels were significantly associated with CR (odds ratio, 3.08; 95% confidence interval [CI], 1.10 to 8.58;P = .03). Moreover, patients with “increased” sL-selectin levels (≥3.12 μg/mL) had shorter event-free survival (EFS) (median 7.3 v 12 months, P = .008) and overall survival (median 1 v 2.05 years, P = .03) than patients with sL-selectin <3.12 μg/mL. Multivariate statistical analysis (adjusted for age and presence of Auer rods) indicated that sL-selectin was an independent prognostic factor for EFS (hazard ratio [HR], 1.96; 95% CI, 1.21 to 3.17, P = .006) and overall survival (HR, 1.80; 95% CI, 1.09 to 2.98; P = .02). Thus, plasma sL-selectin may be a useful prognostic marker in the evaluation of AML at diagnosis.

Abstract
The US National Cancer Institute (NCI) is the world's largest sponsor of clinical trials in cancer treatment and biology, and it is responsible for the reliability of data generated by means of its funding. The cooperative groups supported by the NCI consist of main academic institutions and smaller affiliates of these institutions. The size of these groups, their geographical dispersion, and the number of studies accruing patients at any one time make it a challenge to ensure that all requirements of institutional oversight, patient consent, protocol compliance, and data submission and quality are met. Each cooperative group has established various procedures for quality assurance. These include data coordinators at the data management center of the group, study chairs, and statisticians. In addition, each group has a committee of physician-investigators and clinical research associates who make periodic site visits to all member institutions to audit the on-site medical records of a sample of patients entered at that institution. The study records are compared with the medical records for all aspects of protocol management and data generation. In addition, adherence to requirements for consent-form signing and oversight by an institutional review board is assessed. Deviations from the study requirements are evaluated as being minor or major. A written report of the audit result is provided to both the NCI and the relevant administrative components of the cooperative group. The audit process has uncovered rare instances of scientific improprieties in these NCI-funded clinical trials, but more importantly it has educated investigators and support staff to improve adherence to research and data-collection requirements, which has resulted in greater reliability of study results.

Abstract
The optimal management of acute myeloid leukemia in patients over 60 years-of-age remains a controversial issue. The complete remission rates after conventional induction chemotherapy progressively decreases after the age of 60. This is explained by host-related factors and by differences in the biology of leukemia. The incidence of adverse prognostic factors (trilineage myelodysplasia, unfavorable karyotype, mdrl-positive phenotype) is higher in elderly patients. Three strategies are currently offered to older adults with acute myeloid leukemia: intensive chemotherapy, palliative treatment and attenuated dose chemotherapy. Currently, complete remission rates achieved with conventional chemotherapy range from 40-65% according to inclusion criteria. In the past few years, two approaches have been tested in order to improve the results of induction chemotherapy: modifications of chemotherapy regimens with new intercalating agents (idarubicin, mitoxantrone) and the use of myeloid growth factors. Myeloid growth factors have been administered with two objectives: to reduce the duration of neutropenia and the toxic death rate when given after induction chemotherapy, and to prime leukemic blasts when given during chemotherapy. The results of published placebo-controlled studies are discussed. The issues of palliative treatment and of attenuated dose chemotherapy are also addressed in the review, with special emphasis on the role of oral idarubicin.

Abstract
To determine whether patients with a HLA-identical sibling donor have a better outcome than patients without a donor, an analysis on the basis of intention-to-treat principles was performed within the framework of the EORTC-GIMEMA randomized phase III AML 8A trial. Patients in complete remission (CR) received one intensive consolidation course. Patients with a histocompatible sibling donor were then allocated allogeneic bone marrow transplantation (alloBMT), the patients without a donor were randomized between autologous BMT (ABMT) and a second intensive consolidation (IC2). 831 patients <46 years old and alive >8 weeks from diagnosis were included. HLA typing was performed in 672 patients. AlloBMT was performed during CR1 in 180 (61%) out of 295 patients with a donor. Another 38 patients were allografted: five in resistant disease, 14 during relapse and 19 in CR2. ABMT was performed in 130 (34%) out of 377 patients without a donor in CR1, in six (2%) patients during relapse and in 38 (10%) patients during CR2. The disease-free survival (DFS) from CR for patients with a donor was significantly longer than for patients without a donor (46% v 33% at 6 years; P=0.01, RR 0.78, 95% confidence interval 0.63-0.96). The overall survival from diagnosis for patients with a donor was longer, but not statistically significant, than for patients without a donor (48% v 40% at 6 years; logrank P=0.24). When patients were stratified according to prognostic risk groups, the same trend in favour of patients with a donor was seen for survival duration and the DFS remained significantly longer for this group of patients.

Abstract
Recent attempts to protect hematopoietic progenitor cells from cytarabine (ara-C)-induced toxicity by transfer of the cytidine deaminase (CDD) gene resulted in efficient in vitro inducibility of ara-C resistance. Another enzyme involved in intracellular ara-CTP inactivation is the deoxycytidylate deaminase (dCMPD). We therefore transfected the human dCMPD cDNA gene into murine fibroblasts and investigated the relationship of forced dCMPD expression and resistance induction to ara-C. Several cell lines were established which demonstrated a 1.7-3.5-fold increase in cellular dCMPD activity and an up to 2-fold increase in the IC50 value of ara-C. However, increases in dCMPD activities did not show a positive linear correlation with the induction of ara-C resistance. In addition, CD34 + hematopoietic progenitor cells revealed the highest endogenous dCMPD enzyme levels among different human hematopoietic cells. Thus, despite the documented role for dCMPD in ara-CTP inactivation of certain cell types, these results suggest that the dCMPD gene may prove less useful than the CDD gene as a therapeutic target in attempts to attenuate ara-C-induced bone marrow toxicity.

Abstract
Bone marrow aspirates from 60 patients with acute myeloid leukemia (AML) were investigated using 95% ethanol fixation Papanicolaou stained preparations. The blasts were grouped into those with a clear halo around nucleoli (BCHN) and those without a clear halo. The patients were classified into three groups according to the degree of persistent BCHN at the end of induction therapy: group 1, no BCHN; group 2, less than 1% BCHN; and group 3, 1% or more BCHN. All patients in groups 1 (17 cases) and 2 (12 cases), and 12 of 31 cases in group 3 achieved complete remission (CR). Of 17 patients in group 1, two underwent bone marrow transplantation and two died from infection. Of the 37 patients who achieved CR, relapse was observed in two of 13 patients in group 1, and in all patients in groups 2 and 3. As to the patients treated with N4-behenoyl-1-beta-D-arabinofuranosyl-cytosine + daunorubicin + 6-mercaptopurine + prednisolone (BHAC-DMP) protocol, the percentages and number of BCHN at the diagnosis of AML in group 1 were significantly lower than those of groups 2 and 3. The percentage and number of BCHN at the diagnosis of AML were significant factors for the achievement of CR and for the prediction of long-term outcome. The reduction of BCHN to less than 1% at the end of induction therapy is a good indicator for the achievement of CR, and the disappearance of BCHN is a useful target for a long-lasting first CR; conversely, the persistence of BCHN is a major adverse factor for relapse.

Abstract
Isolated trisomy 11 is the third most common sole trisomy in de novo acute myeloid leukaemia (AML). However, only 49 cases have been published, and for only a fraction of these cases has full description of clinical and haematological features been provided. As a result, little is known about the clinical characteristics of de novo AML patients with solitary trisomy 11. We have identified 13 patients (0.9%) with isolated trisomy 11 among a total of 1496 consecutive adult patients successfully karyotyped as part of a prospective Cancer and Leukemia Group B (CALGB) cytogenetic study (CALGB 8461). Nine patients (69%) were over the age of 60 (range 29-73 years). Eight patients (62%) were diagnosed with AML of FAB M2 subtype, three patients (23%) had FAB M1 AML and one patient each had AML of FAB M0 and M7, respectively. Seven patients (54%) had high, >100 x 10(9)/l, platelet counts (median 102 x 10(9)/l; range 17-207 x 10(9)/l). All patients received CALGB induction therapy with standard doses of cytarabine and daunorubicin. Six patients (46%) achieved a complete remission (CR). The median CR duration was 17.5 months (range 8.7-49.8). Only one patient, who underwent bone marrow transplantation in first CR, continues in initial CR. The median survival was 14.3 months (range 0.5-50.7); only one patient survives. We conclude that de novo AML with isolated trisomy 11 is predominantly associated with older age, M2 and M1 FAB subtypes, high platelet count and few long-term disease-free survivals, although it is currently unknown whether isolated trisomy 11 constitutes an independent prognostic factor.

Abstract
AbstractOlder age is a poor prognosis factor in acute myeloid leukemia (AML). This double-blind trial was designed to test the hypothesis that granulocyte colony-stimulating factor (G-CSF) used as supportive care could improve the treatment of elderly AML patients. Two hundred thirty-four patients 55 or more years of age with a morphologic diagnosis of de novo or secondary AML, French-American-British (FAB) M0-M7, excluding M3, were randomly assigned to a standard induction regimen (daunorubicin at 45 mg/m2 intravenously [IV] on days 1 through 3 and Ara-C at 200 mg/m2 IV continuous infusion on days 1 through 7) plus either placebo or G-CSF (400 μg/m2 IV over 30 minutes once daily). Results are reported here for 211 centrally confirmed cases of non-M3 AML. The two groups were well balanced in demographic, clinical, and hematological parameters, with median ages of 68 years in the G-CSF and 67 years in the placebo groups. The complete response (CR) rate was not significantly better in the G-CSF group: 50% in the placebo and 41% in the G-CSF group (one-tailedP = .89). Median overall survival was also similar, 9 months (95% confidence interval [CI], 7 to 10 months) in the placebo and 6 months (95% CI, 3 to 8 months) in the G-CSF arms (P = .71). We found a significant 15% reduction in the time to neutrophil recovery in the G-CSF group (P = .014). G-CSF had no impact on recovery from thrombocytopenia (P = .80) or duration of first hospitalization (P = .27). When infection complications were evaluated, G-CSF had a beneficial effect on the duration but not on incidence of infection. G-CSF patients had fewer days with fever and shorter duration of antibiotic use. However, there was no difference in the frequency of total documented infections or in the number of fatal infections (19% placebo v 20% G-CSF). In this study of elderly AML patients, G-CSF improved clinical parameters of duration of neutropenia and antibiotic use, but did not change CR rate or survival or shorten hospitalization.

Abstract
BACKGROUND CHOP is currently considered the gold standard of treatment for intermediate grade lymphomas. We designed a new regimen known as 'ATT' (alternating triple therapy) which uses three non-cross resistant combinations in alternating sequence for nine cycles. MATERIALS AND METHODS This is a phase II clinical trial with comparison to CHOP/CMED historical controls using prognostic factors. The tumor score system was used to evaluate the results of this trial. Two hundred sixty-eight eligible patients who had one or more of the following adverse features: bulky disease, elevated LDH or > 1 extranodal site were analyzed. Outcome measures consist of survival and failure free survival. RESULTS At a median follow-up of 32 months, there was no statistically significant difference in survival for those with favorable prognostic factors (tumor score < or = 2). However, there was a statistically significant difference in favor of ATT for those with unfavorable tumor scores. When we examined the failure-free survival of those with unfavorable tumor scores, we again observed a superiority for the ATT regimen over CHOP/CMED but the opposite was true for those with favorable tumor scores. We also found a statistically significant difference in favor of the ATT regimen when compared with CHOP/CMED for patients < or = 60 years old with a tumor score > or = 3, while no advantage was found for those > 60 years. CONCLUSIONS ATT appears more effective but only for patients < 60 years old with unfavorable tumor scores. In those older than 60 years with favorable tumor score, CHOP/CMED appears superior. ATT might be an adequate regimen for young patients with poor prognostic features while CHOP/CMED might be a better choice for those with good prognosis irrespective of age. For those > 60 years with unfavorable tumor scores neither ATT or CHOP/CMED were adequate treatment. Because of the phase II nature of this study, these conclusions should be considered as hypotheses which require prospective testing.

Abstract
Because the majority of acute myeloid leukemia (AML) blasts express the granulocyte-macrophage colony-stimulating factor (GM-CSF) receptor, we are developing a fusion toxin consisting of a truncated diphtheria toxin (DT388) linked to human GM-CSF for multi-drug resistant AML. Our goal was to determine the toxicity and pharmacokinetics of DT388-GM-CSF in C57BL/6 mice. Because human GM-CSF does not cross-react with the mouse GM-CSF receptor, the toxicity observed should be nonspecific toxicity of DT388. We injected C57BL/6 mice i.p. with 0.1, 0.5, 1.0, 1.5, 1.75, 2.0, 3.5, 5.0, or 10 micrograms/day of DT388-GM-CSF for 5 consecutive days. For pharmacokinetics, blood samples were drawn at 20, 40, 60, 120, and 180 min after i.p. administration of 81 micrograms/kg of DT388-GM-CSF. In mice, the LD10 of DT388-GM-CSF is between 84.4 (1.5) and 104.4 (1.75) micrograms/kg (microgram) when administered for 5 consecutive days. All mice receiving > or = 201 micrograms/kg (3.5 micrograms) for 5 consecutive days died. Histopathologic examination of morbid animals showed only renal toxicity with acute proximal tubular necrosis. DT388-GM-CSF is stable in vivo based on nonreducing SDS-PAGE gel of plasma samples of 125I-labeled DT388-GM-CSF injected i.p.. The peak concentration of DT388-GM-CSF was 3.3 x 10(-8) M at 40 min and exhibited a t1/2 of 24 min. Based on its half-life, DT388-GM-CSF concentrations in the plasma are above the concentration inhibiting 50% protein synthesis and inducing apoptosis in 50% of HL-60 cells (AML cell line) for 5.2 h. Only four of 17 mice developed a weak immune response (0.9-160 ng/mL) 3 weeks after treatment. DT388-GM-CSF exhibits a short t1/2, but concentrations exceed those required in vitro to inhibit AML cell lines.

Abstract
We sought to determine the role of granulocyte colony-stimulating factor (G-CSF) as an adjunct therapy in high-dose cytarabine-containing chemotherapy (HD C/T) for children with acute leukemia. Seventeen patients, aged 9 months to 18 years old, 8 ALL and 9 AML, were treated with cytarabine (Ara-C) 1 g/m2 q12h for 8 doses with mitoxantrone, idarubicin, VP-16, or asparaginase. A total of 71 courses of HD C/T was given. G-CSF was not used in 14 courses (Group A). Prophylactic G-CSF was given in 57 courses (Group B) as 200 microg/m2/d SC started one day after the completion of HD C/T and continued until the neutrophil recovery was maintained. The incidences of sepsis per course in Group A and Group B were 35.7% (5/14) and 40.4% (23/57), respectively. While 2 patients in Group A died of sepsis or pneumonia, none in Group B died. The mortality and delay in chemotherapy were fewer in Group B (P = 0.037 and 0.0006, respectively, Fisher exact test). There was a shorter average number of days of neutrophil <500/cumm, antibiotic usage, fever, and hospital stay in Group B (11, 8, 5, 17 days in Group B vs. 21, 17, 10, 37 days in Group A; P = 0.0001, log-rank test; 0.0006, 0.0023, 0.0001, Wilcoxon rank sum test, respectively). The incidence of neutropenic fever was lower in Group B, but the difference did not reach statistical significance (P = 0.06, Fisher exact test). We conclude that G-CSF as an adjunct therapy in HD C/T is effective in reducing mortality, days of neutropenia, antibiotic usage, fever, hospital stay, and frequency of delay in chemotherapy. The efficacy of this treatment approach requires further testing in a randomized, controlled trial.

Abstract
BACKGROUND Much research has been conducted into the pathobiology, diagnosis, and management of acute myeloid leukaemia (AML) since 1980, with major contributions from Australian studies in this period. AIMS To determine whether advances in basic and clinical research into AML have translated into improved survival for patients in the community. METHODS A retrospective survey of records of all patients with AML presenting to the Royal Melbourne Hospital (RMH) over a 16 year period, analysed according to induction therapy and established prognostic factors. Between 1980 and December 1996 223 (98%) of 227 patients were evaluable. RESULTS The probability of survival at five years for patients treated since 1990 has improved significantly compared to the cohort treated between 1980-89 (34 +/- 5% vs 4 +/- 2%; mean +/- standard error). This benefit is most evident in patients less than 60 years of age (50 +/- 7% vs 11 +/- 4%). Successive induction protocols in the context of clinical trials conducted since 1985 contributed to improved outcomes. The selective application of bone marrow transplantation, and use of retinoic acid as induction therapy for acute promyelocytic leukaemia has also improved survival. Despite increases in dose-intensity, early death rates for patients undergoing induction therapy fell during the study period. CONCLUSIONS Participation in clinical and basic research with the development of more intense and specific treatments for patients with AML has contributed to better outcomes, underpinned by improvements in supportive care.

Abstract
BACKGROUND Three strategies are used to prevent relapse in patients with acute myeloid leukaemia in first remission. Most of those with suitable donors are offered allogeneic haemopoietic-stem-cell transplant. Other patients may receive intensive chemotherapy or autologous transplantation; we undertook this randomised prospective trial to assess which is the better option. METHODS After three courses of intensive chemotherapy, bone marrow was harvested from patients (<56 years of age) in remission who lacked an HLA-matched sibling donor. These patients were then randomised to receive, after one more course of chemotherapy, no further treatment (n=191) or an autologous bone-marrow transplant (BMT) after preparation with cyclophosphamide and total-body irradiation (n=190). Outcome comparisons were by intention to treat with adjustment for the most important risk factors for relapse. FINDINGS 381 patients were randomised (38% of those eligible). Of the 190 patients allocated autologous BMT, 126 received it. On intention-to-treat analysis the number of relapses was substantially lower in the autologous BMT group than in the group assigned no further treatment (64/190 [37%] vs 101/191 [58%], p=0.0007), resulting in superior disease-free survival at 7 years (53 vs 40%; p=0.04). These benefits were observed in all risk groups and age-groups. There were more deaths in remission in the autologous BMT group than in the no further treatment group (22 [12%] vs 7 [4%], p=0008). In children (<15 years) and patients with good-risk disease, survival from relapse in the no further treatment group was 35% and 38% at 2 years. There was an overall survival advantage in the autologous BMT group at 7 years (57 vs 45%, p=0.2). INTERPRETATION The addition of autologous BMT to four courses of intensive chemotherapy substantially reduces the risk of relapse in all risk groups, leading to improvement in long-term survival. The good chance of salvage for children or patients with good-risk disease who relapse from chemotherapy, and the mortality, morbidity, late effects, and expense of autologous BMT, suggest that delay of autograft until second remission in these two groups may be appropriate.

Abstract
BACKGROUND Clostridium difficile colitis in the cancer patient receiving chemotherapy is a frequent cause of morbidity which may prolong hospitalization. Techniques for identifying infection often delay the initiation of therapy. PATIENTS AND METHODS In this retrospective case-control analysis, we identified predictors for C. difficile-associated diarrhea in 29 patients hospitalized from 1988 to 1993 on a hematologic malignancy/bone marrow transplant unit (hospital A). We then validated our model with 58 C. difficile cases and 74 controls admitted to an oncology unit from a different institution (hospital B). RESULTS We found that low intensity of chemotherapy (P < 0.001), lack of parenteral vancomycin use (P = 0.03) and hospitalization within the past two months (P = 0.05) were independently predictive of C. difficile colitis by multivariate analysis. These variables were weighted for predictive capability using a receiver operator characteristic score; low intensity chemotherapy was assigned two points, lack of parenteral vancomycin received one point and prior hospitalization one point (P < 0.001 by chi 2 for trend). The receiver operating characteristic (ROC) curve areas were 0.78 for patients at hospital A and 0.70 at hospital B indicating moderate drop off in discrimination. Compared to hospital A patients, hospital B patients hospitalized between 1989 and 1994 were more often women (P = 0.04), received less systemic vancomycin (P = 0.01), were less frequently neutropenic (P < 0.05), and received less intense chemotherapy regimens (P < 0.05). Despite these differences in demographics in patients between these institutions, our predictive model was validated in hospital B patients (P = 0.02 by chi 2 for trend). CONCLUSIONS The results of this study may help clinicians predict the risk of C. difficile disease in the hospitalized immunocompromised oncology patient and may help guide empiric therapy while awaiting results of stool toxin assays.

Abstract
Between January 1990 and May 1994, 59 previously untreated adult patients with acute myeloblastic leukemia (AML) were treated with a combination of behenoyl-cytosine-arabinoside (BHAC), daunorubicin (DNR), 6-mercaptopurine (6-MP) and prednisolone (PSL). Forty one patients (69.5%) achieved complete remission (CR). The Kaplan-Meier analysis revealed an actuarial probability for remaining in remission of 36% in patients who achieved remission and a survival of 29% in all patients at 5 years. A favorable factor relative to achieving CR was performance status (P=0.04). In addition the presence of 300 cells/microl or less of residual leukemic cell counts in the bone marrow at the end point of induction therapy tended to favor remission (P=0.06) using the multivariate analysis with a multiple logistic regression model. In addition the residual leukemic cells counts of less than 300/microl in the bone marrow at the end point of induction therapy was the most significant factor for durable remission (P=0.05) by the Cox's proportional hazard model. We concluded that residual leukemic cells counts in the bone marrow at the end point of intensive induction therapy is a valuable prognostic factor for adults receiving response-oriented individualized induction therapy for AML.

Abstract
BACKGROUND The purpose of this study was to compare the long-term psychosocial adaptation of Hodgkin's disease and adult acute leukemia survivors. PATIENTS AND METHODS Two hundred seventy-three Hodgkin's disease (HD) and 206 adult acute leukemia (AL) survivors were interviewed by telephone concerning their psychosocial adjustment and problems they attributed to having been treated for cancer, using identical research procedures and a common set of instruments. The following measures were used: Psychosocial Adjustment to Illness Scale (PAIS); Brief Symptom Inventory (BSI); current Conditioned Nausea and Vomiting triggered by treatment-related stimuli (CNVI); Indices of Employment, Insurance and Sexual Problems Attributed to Cancer; Negative Socioeconomic Impact of Cancer Index (NSI). All participants had been treated on one of nine Hodgkin's disease or 13 acute leukemia Cancer and Leukemia Group B (CALGB) clinical trials from 1966-1988, and had been off treatment for one year or more (mean years: HD = 5.9; AL = 5.6). RESULTS HD survivors' risk of having a high distress score on the BSI was almost twice that found for AL survivors (odds ratio = 1.90), with 21% of HD vs. 14% of AL survivors (P < 0.05) having scores that were 1.5 standard deviations above the norm, suggestive of a possible psychiatric disorder. HD survivors reported greater fatigue (POMS Fatigue, P = 0.01; Vigor Subscales, P = 0.001), greater conditioned nausea (CNVI, P < 0.05), greater impact of cancer on their family life (PAIS Domestic Environment, P = 0.004) and poorer sexual functioning (PAIS Sexual Relationships, P = 0.0001), than AL survivors. CONCLUSIONS Treatment-related issues may have placed HD survivors at a greater risk for problems in long-term adaptation than AL survivors.
