Abstract
A randomized inter-group trial comparing more intensive treatment strategies to a common standard arm 3 + 7 (CSA) was conducted in patients with non-M3 AML. Untreated patients ≥ 60 years were allocated to the CSA (n = 132) or to the study group arms (n = 1154) of the AMLCG (TAD/HAM versus HAM/HAM ± G-CSF followed by TAD and maintenance) and the OSHO (intermediate-dose ara-C/mitoxantrone followed by ara-C/mitoxantrone). Median age of the 1147 eligible patients was 69 (range 60-87) years. CR/CRi status at 90 days was not significantly different between the CSA (54% (95%CI: 45-64)) and the study group arms (53% (95%CI: 47-60) and 59% (95%CI: 58-63)). The five-year event-free survival (EFS) probability (primary endpoint) was 6.2% (95%CI: 2.7-14.0) in the CSA, 7.6% (95%CI: 4.5-12.8) in study group A and 11.1% (95%CI: 9.0-13.7) in B. The 5-year OS was 17.2% (95%CI: 11.0-26.9), 17.0% (95%CI: 2.0-23.9), and 19.5% (95%CI: 16.7-22.8) in CSA, study group A and B, respectively. Neither study group differed significantly from the CSA regarding EFS, OS, or relapse-free survival. In multivariate analyses, allocation to the treatment strategy was not significantly associated with the time-to-event endpoints. The evaluation of more intensive treatment strategies did not show clinically relevant outcome differences when compared to CSA.

Abstract
Relapse of acute leukemia is a frequent complication with uncertain outcome and poorly defined risk factors. From 1621 patients entered into two prospective clinical trials (AML02; n = 740 and AML04; n = 881), 74.2% reached complete remission (CR) 1 after induction(s) and 59 patients after additional induction ± hematopoietic cell transplantation (HCT). Of the non-refractory patients, 48.4% with a median age of 63 (range 17-85) years relapsed. Relapses occurred within 6 months after CR in 46.5%, between 7 and 18 months in 38.7%, and after 18 months in 14.8% of patients. Relapse treatment resulted in CR2 in 39% of patients depending upon age (54.5% of ≤ 60 and 28.6% of > 60 years), duration of CR1, and treatment of relapse. Overall survival (OS) was 10.9 (7.4-16.2) %, but OS after HCT ± intensive chemotherapy (ICT) was 39.3% (31.8-48.6) at 5 years and not different in younger and older patients. Donor lymphocyte infusion ± chemotherapy and ICT alone resulted only in OS of 15.4% and of 5%, respectively. Independent favorable factors for OS were long CR1 duration, and HCT, while non-monosomal disease was beneficial for OS in elderly patients. Leukemia-free survival [LFS; 24.9 (19.5-31.7) % at 10 years] was affected by similar risk factors. In a competing risk model, the relapse incidence at 5 years was 53.5 ± 3.5% and the non-relapse mortality rate 21.7 ± 2.9%. Lower relapse incidence was observed in patents with HCT, long CR1 duration, and female gender. Risk factors for non-relapse mortality were HCT in younger and type of AML in elderly patients. In conclusion, allogeneic HCT ± IC improved the results in relapsed AML in younger and elderly patients. Increasing CR2 rates and HCT frequency will be the challenge for the next years. Relapse of the disease remains the major problem.

Abstract
7003 Background: Even after reaching initial CR, most AML patients > 60 years relapse within 2 years of diagnosis. Cytogenetic high risk AML (abn 3q26, abn 11q23, -5/5q-, -7/7q- and complex) has an even worse prognosis. Attempts to improve survival by intensifying consolidation chemotherapy have so far failed. We investigated the role of allogeneic HCT in comparison to chemotherapy among patients with high risk cytogenetics entered into the OSHO AML 97 protocol. Methods: Initial treatment consisted of a course of induction therapy (AraC 2 g/m2 iv on day 1,3,5,7 + mitoxantrone 10 mg/m2 iv day 1 –3, repeated once in case of PR) followed by one consolidation course (AraC 240 mg/m2 iv day 1 –5 + mitoxantrone 10 mg/m2 iv day 1 –2). Patients in CR1 after the consolidation I were either treated with an additional consolidation therapy or with an allogeneic HCT from related (n=2) or unrelated (n=10) donors. Transplant patients were conditioned with fludarabine and TBI 200 cGy and immunosuppressed with cyclosporine and mycofenolate mofetil. Results: A total of 347 patients are evaluable. Of 105 (33%) patients with high-risk cytogenetics, 53 (50%) went into remission after one or two cycles of induction chemotherapy. Of these 53 patients, 42 received consolidation I and 35 patients were available for either consolidation II (n=23) or HCT (n=12). Median age of the patients receiving chemotherapy was 64 (range 61–77) years and that of the transplant patients was 64 (range 61–68) years. LFS at 4 years was 42 ± 14% after HCT and 15 ± 8% after chemotherapy. Major differences in relapse incidences were seen between the two groups, with the lowest RI at 4 years after HCT (36 ± 15%) followed by chemotherapy (85±8%, p<0.04). Treatment related mortality at 4 years was 35±17% and 0±0% for patients receiving HCT and chemotherapy, respectively (p<0.05). Conclusions: From these results, we conclude that consolidation with allogeneic HCT after minimal conditioning is superior to chemotherapy even in older patients with high risk cytogenetics. While differences in TRM were seen between the treatment arms, a lower relapse incidence after related and unrelated HCT contributed to the improved LFS. No significant financial relationships to disclose.

Abstract
BACKGROUND AND OBJECTIVE Allogeneic transplantation can not be offered to many patients due to potential side-effects of conventional conditioning. Dose-reduced conditioning approaches improve tolerability, however, treatment efficacy may be reduced as well. We have, therefore, developed a dose intense but toxicity reduced conditioning regimen based on treosulfan and fludarabine and report first results. PATIENTS AND METHODS 65 patients with a median age of 50 years were transplanted from related (n = 21) or unrelated donors (n = 44) after conditioning with treosulfan (3 x 10, 3 x 12 or 3 x 14 g/m(2) i. v.) and fludarabine (5 x 30 mg/m(2) i. v.). 21 patients were in complete remission (CR) and 44 patients had not reached a CR at the time of transplantation. 59 of 65 patients were considered unfit for a conventional conditioning regimen. RESULTS The actuarial overall survival after 3 years is 59.2 %, the event-free survival 40.1 %. Patients with a related donor or transplantation in CR had a better overall (85.4 resp. 74.2 %) and event-free survival (52.2 % resp. 61.9 %). The cumulative incidence of relapse at 3 years was 26.2 %. Non-relapse mortality at day 100 is 17.4 % (cumulative incidence). In stepwise Cox regression analyses for overall survival, event-free survival and non-relapse mortality the covariables transplantation in CR vs. not in CR and the donor status were shown to be influential. CONCLUSIONS These results with a conditioning therapy of treosulfan and fludarabine indicate that patients despite higher age, concomitant disease or after intensive pretreatment can be successfully transplanted without increased treatment-related mortality.

Abstract
The German Multicentre acute lymphoblastic leukaemia (ALL) study group (GMALL) performed a pilot study using pegylated asparaginase (PEG-ASP) in combination with high-dose methotrexate as consolidation therapy in the 05/93 protocol. The aim of the study was an intra-individual comparison of two different doses of PEG-ASP in 26 patients, with regard to the depletion of asparagine in serum and toxicity. 'Pharmacokinetic' monitoring was performed to evaluate the effect of an intra-individual dose escalation of PEG-ASP from 500 to 1000 U/m2 intravenously in successive doses. Serum asparaginase activity was targeted at > or =100 U/l for 1 week and > or =50 U/l for 10 d. The second course of PEG-ASP was administered to 23 patients. Due to hypersensitivity reactions in five patients, only 18 patients were evaluable for pharmacokinetic monitoring. With respect to the PEG-ASP activity, an effective depletion of asparagine could be postulated in the majority of patients during 10 d after the first administration. The effect of an intraindividual dose escalation form 500 to 1000 U/m2 was evaluable in 17 of 22 patients. An increment in peak PEG-ASP activity >70% was observed in 65% of the patients. PEG-ASP was well tolerated. Despite the long half-life of PEG-ASP, neither pancreatic nor central nervous toxicities occurred among the 26 adult patients treated in this pilot study.

Abstract
The 1-pool-model of sodium kinetics during hemodialysis is based upon the assumption of an immediate compensation of osmotic shifts. This assumption is not supported by measurements of plasma sodium, total protein concentration and colloid osmotic pressure kinetics. When a high dialysate sodium concentration is applied, an inflow of sodium into the plasma space occurs, which results in an osmotic suction and thus a plasma dilution. These conditions can be represented by a 2-pool-model taking into consideration capillary filtration. The results indicate that following the first treatment period the sodium kinetics are sufficiently explained by a 1-pool-model with the total body water as distribution volume. Both the plasma sodium concentration and the eliminated sodium at the end of a hemodialysis treatment can be described to an acceptable level by the 1-pool-model. The input of the measured in-vivo sodium dialysance value (or alternatively the urea clearance) is necessary.

Abstract
Considering the plasma colloid osmotic pressure (COP) as a possible parameter for the monitoring of dialysis treatment compatibility, a characteristic time course was found. The COP and the total protein concentration very often do not increase significantly during the first treatment hour in spite of ultrafiltration. An increase in the plasma sodium concentration, which was higher than expected, was found to be the reason for a plasma dilution effect. This can be explained by a transcapillary sodium transfer coefficient which is not infinitely high as assumed in single-pool sodium modelling. From a 2-pool model considering the plasma volume as a separate pool and including capillary filtration time courses for plasma sodium, total protein concentration and COP could be calculated, which was very similar to the measured curves.
