Abstract
PURPOSE Stem cell transplantation (SCT) can definitely cure chronic myeloid leukemia (CML), a rare disease in childhood. We prospectively evaluated the results of early SCT in pediatric CML after standardized pretreatment with hydroxyurea+/-interferon. PATIENTS AND METHODS Between 1995 and 2004, 200 children (median age: 12.4 years) were enrolled and stratified: given the availability of an HLA-matched related donor (MRD), SCT was scheduled within 6 months and otherwise from an unrelated donor (UD) within 12 months following diagnosis. RESULTS 176 patients underwent SCT; from MRD within median 4 months and from UD within median 11 months after diagnosis. At SCT, 158 patients were in chronic phase (CP1 or CP2), 9 patients were in accelerated phase and 9 patients were in blast crisis (BC). The conditioning regimen - total body irradiation or busulfan - exerted no different impact on overall survival (OS). Probability of OS at 5 years was 87+/-11% if grafted from a sibling (n=41), 52+/-9% from matched UD (MUD, n=71), and 45+/-16% from mismatched donors (MMD, n=55), respectively. A trend for better OS in CP1 was observed if SCT was performed within 6 months (n=49; 74+/-9%), compared to 7-12 months (n=52; 62+/-15%), and >12 months (n=43; 62+/-17%) after diagnosis, respectively (p=0.157). Probability of relapse at 5 years was 20+/-12%. Transplant-related mortality and graft-versus-host disease mainly contributed to the inferior outcome in UD and HLA-mismatched SCT. CONCLUSION These data from the first prospective trial on CML restricted to children and adolescents might be considered for decision making when balancing the risks of SCT against the increasing use of imatinib as upfront treatment for CML.

Abstract
We examined the role of total body magnetic resonance imaging (TB-MRI)-governed involved compartment irradiation (ICI) and high-dose chemotherapy (HDC), followed by stem cell rescue (SCR) in patients with high-risk Ewing tumors (ETs) with multiple primary bone metastases (high-risk ET-MBM). Eleven patients with high-risk ET-MBM receiving initial assessment of involved bones by TB-MRI were registered from 1995 to 2000 (group A). In all, 6 patients out of 11 had additional lung disease at initial diagnosis; all had multifocal bone disease with more than three bones involved. After systemic induction with etoposide, vincristine, adriamycin (doxorubicin), ifosfamide, and actinomycin D (EVAIA) or VAIA chemotherapy, ICI of all sites positive by TB-MRI was administered, followed by HDC and SCR. A second group matched for observation period and consisting of 26 patients with more than three involved bones at diagnosis was treated with the European Intergroup Cooperative Ewing Sarcoma Study-92 (EICESS-92) protocol (group B). These patients did not receive TB-MRI and consequently did not receive TB-MRI-governed ICI, or HDC and SCR. Survival in group A vs group B was 45 vs 8% at 5 years and 27 vs 8% at 10 years after diagnosis (log rank and Breslow: P<0.005). We conclude that TB-MRI-governed ICI followed by HDC and SCR in ET-MBM is feasible and warrants further evaluation in prospective studies.

Abstract
Fatal problems encountered in allogeneic stem cell transplantation include EBV reactivation and post transplant lymphoproliferative disorders (PTLDs) with high mortality rates. We performed a retrospective analysis in all consecutive adult and pediatric EBV reactivations and PTLD during a period of 8.5 years. There were 26 patients with EBV reactivation/PTLD out of a total of 854 transplantations giving an overall incidence of 3.0%. Specifically, the incidence of EBV-PTLD was 1.3%, whereas that of EBV reactivation was 1.8%. Median age was 46.0 and 11.0 years in the adult and pediatric patients, respectively. There were high rates (54%) of concomitant bacterial, viral, fungal and parasitic infections at the time of EBV manifestation. Variable treatment regimens were applied including in most cases an anti-CD20 regimen often in combination with virustatic compounds, polychemotherapy or donor lymphocytes. The mortality rates were 9 of 11 (82%) in patients with EBV-PTLD and 10 of 15 (67%) in patients with reactivation. Only 7 of 26 patients (27%) are alive after a median follow-up of 758 days (range 24-2751). The high mortality rates of EBV reactivation and of EBV-PTLD irrespective of multimodal treatment approaches emphasize standardization and optimization of post transplant surveillance and treatment strategies to improve control of these often fatal complications.

Abstract
A total of 1111 children with acute myeloblastic leukaemia (AML) were treated in four consecutive Berlin-Frankfurt-Münster (BFM) studies from 1978 to 1998. The first cooperative trial AML-BFM 78 established intensive chemotherapy with seven drugs, CNS irradiation and 2-year maintenance, achieving a long-term survival (overall survival (OS)) of 40%. Induction intensification in AML-BFM 83 resulted in significant improvement of disease-free survival (DFS). The risk of haemorrhage, especially in children with hyperleukocytosis, proved the high relevance of supportive care. In AML-BFM 87, the benefit of CNS irradiation in preventing CNS/systemic relapses was demonstrated. In AML-BFM 93, the introduction of idarubicin during first induction followed by intensification with HAM increased the 5-year EFS, DFS and OS to 50+/-2, 61+/-3 and 57+/-2%, respectively. Stem cell transplantation (SCT), as applied in high-risk patients with a matched related donor, did not significantly improve the outcome compared to chemotherapy alone. In spite of treatment intensification, the therapy-related death rate decreased from trial to trial, mainly during induction. The future aim is to reduce long-term sequelae, especially cardiotoxicity, by administration of less cardiotoxic drugs, and toxicity of SCT by risk-adapted indications. The AML-BFM studies performed in three European countries with >70 cooperating centres have significantly improved the outcome in AML children; nevertheless, increasing experience with these intensive treatment regimens is of fundamental importance to reduce fatal complications.

Abstract
We report the results of 84 patients with ALL after related (n = 46) or unrelated (n = 38) allogeneic SCT. Mean recipient age was 23 years (range: 1-60) and median follow-up was 18 months (range: 1-133). Forty-three patients were transplanted in CR1; 25 in CR2 or CR3; four were primary refractory; four in PR; eight in relapse. The conditioning regimen consisted of TBI/VP16/CY (n = 76), TBI/VP16 (n = 2), TBI/CY (n = 2), Bu/VP16/CY (n = 4). The OS at 3 years was 45% (44% unrelated, 46% related). Univariate analysis showed a significantly better OS for patients <18 years (P=0.03), mismatched sex-combination (P = 0.03), both with a stronger effect on increasing OS after unrelated SCT. Factors decreasing TRM were patient age <18 years (P = 0.004), patient CMV-seronegativity (P = 0.014), female recipient (P = 0.04). There was no significant difference in TRM and the relapse rate was similar in both donor type groups. Multivariate analysis showed that factors for increased OS which remained significant were mismatched sex-combination (RR: 0.70,95% CI: 0.51-0.93, P = 0.015), patient age < 18 years (RR: 0.66, 95% CI: 0.47-0.93, P = 0.016). A decreased TRM was found for female patients (RR: 0.56, 95% CI: 0.33-0.98, P=0.042), negative CMV status of the patient (RR: 0.57, 95% CI: 0.36-0.90, P = 0.015). Unrelated stem cell transplantation for high-risk ALL patients with no HLA-compatible family donor is justifiable.

Abstract
We examined retrospectively 44 patients with refractory acute leukemia (acute myeloid leukemia (AML)/acute lymphoblastic leukemia=25/19) who underwent allogeneic transplantation at our center between 11/1990 and 04/2004. The median leukemic blasts was 25% and age 28 years (range, 3-56). Twenty-one patients had untreated relapse, 13 failed reinduction, eight in partial remission and two aplastic. Conditioning was myeloablative using cyclophosphamide, busulfan, total-body irradiation and etoposide (Bu/Cy/VP, n=22; TBI/Cy/VP, n=17; others, n=5) followed by marrow or peripheral blood transplant (n=23/21) from unrelated or related donors (n=28/16). All patients had graft-versus-host disease (GVHD) prophylaxis with cyclosporin and methotrexate. One patient experienced late graft failure. Severe acute-GVHD and chronic-GVHD appeared in eight and 14 patients, respectively. Thirteen patients (30%) remain alive after a median of 25.3 months (range, 2.4-134.1); with 31 deaths, mostly from relapse (n=15) and infections (n=12). Overall survival (OS) and progression-free survival (PFS) at 5 years was 28 and 26%, respectively. OS and PFS were significantly better with blasts < or =20% and time to transplant < or =1 year while transplant-related mortality was less with the use of TBI. We conclude that patients with refractory leukemia can benefit from allogeneic BMT, especially with < or =20% marrow blast.

Abstract
We investigated the efficacy of an antithymocyte globulin/cyclophosphamide preparative regimen prior to allogeneic stem cell transplantation from HLA-identical siblings in patients with severe aplastic anemia. Since 1990, 21 patients, 6 males and 15 females, with a median age of 25 years (range: 7-43) have been enrolled in the protocol consisting of 200 mg/kg cyclophosphamide and 90-120 mg/kg antithymocyte globulin (ATG, rabbit, Fresenius, Bad Homburg, Germany). For further graft-versus-host disease (GVHD) prophylaxis all patients received cyclosporin A and a short course of methotrexate (MTX). Only one patient had a primary graft failure (5%). All other patients engrafted with a leukocyte count >1.0 x 10(9)/l and a platelet count >20 x 10(9)/l after a median of 19 (range: 11-28) and 26 days (range: 13-67), respectively. No late graft failure or relapse was observed. Two patients experienced mild acute GVHD grade I (10%), and one patient developed grade II GVHD (5%). No severe grade III/IV GVHD was observed; 17% of the patients developed limited chronic GVHD. The treatment-related mortality was 14% and mainly due to fungal infection. After a median follow-up of 70 months (range: 2-139), the estimated overall and event-free survival at 10 years for all patients is 86% (95% confidence interval: 70-100%). We conclude that ATG plus cyclophosphamide is an effective conditioning regimen in patients with aplastic anemia undergoing stem cell transplantation with a low treatment-related mortality, resulting in an excellent outcome.

Abstract
BACKGROUND Unrelated donor (UD) hematopoietic stem cell transplantation (HSCT) is accepted as a therapy for leukaemic diseases and varying inborn diseases if a suitable related donor cannot be found. The goal of immunosuppressive therapy with UD-HSCT is an effective prevention of graft-versus-host-disease (GvHD) on one hand. On the other hand an optimal balance with immunocompetence of the transplanted bone marrow is desirable in order to prevent graft failure, infection and, in the case of leukaemic diseases, potentially control the underlying disease. PATIENTS AND METHODS Between 1992 and 2000 49 patients aged 11 months to 16.7 years received an UD-HSCT in Hamburg. Underlying diseases were leukaemia or MDS in 35, of these ALL in 21, hemophagocytic lymphohistiocytosis (HLH) in 9, immunodeficiency or inborn error of metabolism in 5 patients. GvHD-prophylaxis consisted of a combination of Cyclosporin A (CSA), methotrexate (MTX), metronidazole, IgM-enriched iv-immunoglobulin (ivIg) (Pentaglobin(R)) or ivIgG and anti-thymocyte-globulin (ATG). Within the same time span 10 patients with ALL received a matched related donor HSCT (MRD-HSCT). GvHD-prophylaxis in these patients was done without ATG in 8 of 10 cases. UD-HSCT were analyzed for survival, relapse and toxicity. Probability of survival of the patients with ALL after UD-HSCT was compared with results of MRD-HSCT in children with ALL. RESULTS The Kaplan-Meier estimates of three year overall-survival (OS) were 74 % for all patients. Probability of disease-free survival (DFS) at three years was 62 % for leukaemia/MDS-patients and 100 % for the HLH-patients. Acute GvHD (aGvHD) grades II or III occurred in 51 % of patients. Chronic GvHD (cGvHD) occurred in 22 % of patients. There were 5 cases of treatment-related mortality (TRM). Probability of DFS for patients with ALL at three years was 65 % after UD-HSCT and 30 % in the patients after MRD-HSCT. CONCLUSIONS UD-HSCT in children is an effective and safe therapy. A GvHD-prophylaxis regimen combining the standard immunosuppressive agents CSA and MTX with ivIg, metronidazole and serotherapy using ATG may result in a low incidence of severe GvHD-complications and low TRM rate without increase in relapse rates.

Abstract
A major problem after autologous or allogeneic stem cell transplantation is prolonged thrombocytopenia. There are several studies published about correlations of the composition of the graft and time to platelet engraftment for autologous transplantation but only a few studies for allogeneic transplantation. In our study, we wanted to find out whether the correlation between the time to platelet engraftment and amount of transplanted CD34(+)CD41(+) cells described previously after autologous peripheral blood stem cell transplantation could be reproduced in the allogeneic bone marrow transplantation setting. We found correlations not only for the number of transplanted CD34(+) cells with the time to leukocyte engraftment (r = -0.32, p = 0.045) but also for the number of transplanted CD34(+)CD41(+) cells and time to platelet engraftment (r = -0.34, p = 0.038), which were both statistically significant. A significant correlation between transplanted CD34(+) cells versus platelet engraftment and transplanted CD34(+)CD41(+) cells versus leukocyte engraftment was not found. The finding that the amount of committed megakaryocyte progenitor cells in the graft is an important predictive factor for platelet engraftment after allogeneic bone marrow transplantation might be the base for future studies of ex vivo expansion of clonable megakaryocyte precursors.

Abstract
BACKGROUND Denaturing HPLC (DHPLC) can be used to screen DNA for known and unknown mutations. We describe a novel, HPLC-based method for discrimination among polyclonal, oligoclonal, and/or clonal T-cell receptor gamma (TCR-gamma) rearrangements in samples from children with newly diagnosed acute lymphoblastic leukemia. METHODS TCR rearrangements were PCR amplified from initial leukemic samples and, after heteroduplex-induction, the clonality status of each product was evaluated. To attain this, we used DHPLC on a high-resolution micropellicular matrix. Running conditions were established by melting-curve analysis of known clonal and polyclonal products and melting-point prediction software. Elution profiles were studied at 50 degrees C (native) and, to achieve optimal separation, at different column temperatures between 56 and 64 degrees C. RESULTS For VgammaI-Jgamma1.3/2.3 rearrangements, an analysis temperature of 60 degrees C with a linear triethylammoniumacetate-acetonitrile gradient separated clonal bands from the polyclonal background amplification. Less than 15% clonal PCR product was detectable in mixtures of initial leukemic cell DNA and polyclonal DNA. Biallelic rearrangements produced two sharp peaks. Clonality of PCR products from 100 initial leukemic samples was completely identified in all investigated cases. CONCLUSIONS Heteroduplex analysis with standardized DHPLC conditions simplifies the detection of unknown clonal or polyclonal TCR rearrangements in newly diagnosed leukemias. Clonal targets for detection of minimal residual disease are available after a short, automated analysis of PCR amplified rearrangements.

Abstract
We investigated the feasibility and efficacy of a fludarabine-based dose-reduced conditioning regimen followed by stem cell transplantation from related (n = 5) or unrelated HLA-matched donors (n = 7) in 12 patients with high risk MDS, who were not eligible for a standard myeloablative conditioning regimen. The conditioning regimen consisted of fludarabine 30 mg/m(2) daily for 6 days, busulfan 4 mg/kg daily for 2 days and anti-thymocyte globulin (ATG, rabbit) 10 mg/kg daily for 4 days in 11 patients, while one patient received fludarabine, ATG, cyclophosphamide and thiotepa. Graft-versus-host disease prophylaxis consisted of cyclosporine and a short course of methotrexate. The median age of the patients was 53 years (range 37-59). The median percentage of blasts in bone marrow aspirate at transplantation was 15% (range <5% to 35%). Diagnosis at transplant was RA (n = 1), RAEB (n = 5), RAEB-T (n = 5) and sAML (n = 1). A complex karyotype including monosomy 7 was noted in five patients. The reasons for using a dose-reduced conditioning regimen were prior autologous/syngeneic BMT (n = 4), active fungal infection (n = 2) or age/reduced performance status (n = 6). Engraftment was observed in all patients with complete donor chimerism. The incidence of acute GVHD (grade II-IV) was 33%. Eight patients died during follow-up due to relapse (n = 4), liver toxicity (n = 2), aspergillus (n = 1) or aGVHD grade IV (n = 1). After a median follow-up of 19 months, the 2-year estimated disease-free survival is 12% (95% CI: 2-23%) and the overall survival is 26% (95% CI: 4-52%). Fludarabine dose-reduced conditioning prior to allogeneic stem cell transplantation in high risk MDS patients, who were not eligible for standard transplantation, resulted in stable engraftment with complete chimerism, but the toxicity and relapse rate were considerable.

Abstract
BACKGROUND In the multicenter trial AML-BFM 93 daunorubicin or idarubicin was randomly applied in all patients during induction in combination with cytarabine and etoposide. After induction all patients were stratified to the standard or high risk group. To improve outcome in high risk patients high dose cytarabine and mitoxantrone (HAM) was introduced. The placing of HAM as either the 2nd or 3rd therapy block was randomized to evaluate the efficacy and toxicity accordingly. PATIENTS AND METHODS 471 children with de novo AML entered the trial AML-BFM 93 (161 standard risk, 310 high risk). RESULTS Overall, 387 of 471 (82 %) patients achieved remission, 5-year survival, event free survival (EFS), and disease free survival were 60 % SE 3 %, 51 % SE 2 % and 62 % SE 3 %, respectively. Idarubicin-based induction resulted in a significantly better blast cell reduction in the bone marrow on day 15 (25 of 144=17 % patients with > 5 % blasts compared to 46 of 149=31 % patients after daunorubicin, pchi(2)=0.01). This was, however, mainly seen in high risk patients treated with idarubicin (19 % vs. 38 %, pchi(2)=0.007). Cardiotoxicity, WHO grade 1 - 3 shortening fraction reduction after induction occurred in 6 % patients in both arms. In the total group of patients probabilities of five years event-free survival and disease-free survival were similar for patients treated with daunorubicin or idarubicin. However, in patients presenting with more than 5 % blasts on day 15 there was a trend for a better outcome after treatment with idarubicin (p logrank 0.06). Outcome in high risk patients was superior in study 93 compared to study 87 (remission rate and 5-year pEFS in study AML-BFM 93 vs. study 87: 78 % vs. 68 %, p=0.007, and 44 % vs. 31 %, p logrank=0.01). The placing of HAM as the 2nd or 3rd therapy block was of minor importance. However, patients who received the daunorubicin treatment during induction benefited from early HAM. CONCLUSION Compared to study AML-BFM 87 treatment results in study AML 93 improved significantly in high risk patients. This can partly be contributed to the better response on day 15 after idarubicin induction but is mainly due to the introduction of HAM.

Abstract
PURPOSE To improve outcome in high-risk patients, high-dose cytarabine and mitoxantrone (HAM) was introduced into the treatment of children with acute myelogenous leukemia (AML) in study AML-BFM 93. Patients were randomized to HAM as either the second or third therapy block, for the purpose of evaluation of efficacy and toxicity. PATIENTS AND METHODS A total of 471 children with de novo AML were entered onto the trial; 161 were at standard risk and 310 were at high risk. After the randomized induction (daunorubicin v idarubicin), further therapy, with the exception of HAM, was identical in the two risk groups and also comparable to that in study Acute Myeloid Leukemia-Berlin-Frankfurt-Münster (AML-BFM) 87. RESULTS Overall, 387 (82%) of 471 patients achieved complete remission, and 5-year survival, event-free survival (EFS), and disease-free survival rates were 60%, 51%, and 62%, respectively. Idarubicin induction resulted in a significantly better blast cell reduction in the bone marrow on day 15. Estimated survival and probability of EFS were superior in study AML-BFM 93 compared with study AML-BFM 87 (P =.01, log-rank test). This improvement, however, was restricted to the 310 high-risk patients (remission rate and probability of 5-year EFS in study AML-BFM 93 v study AML-BFM 87: 78% v 68%, P =.007; and 44% v 31%, P =.01, log-rank test). Probability of 5-year EFS among standard-risk patients in study AML-BFM 93 was similar to that in study AML-BFM 87 (65% v 63%, P = not significant). Whether HAM was placed as the second or third therapy block was of minor importance. However, patients who received the less intensive daunorubicin treatment during induction benefited from early HAM. CONCLUSION Improved treatment results in children with high-risk AML in study AML-BFM 93 must be attributed mainly to the introduction of HAM.

Abstract
We evaluated the cytomegalovirus (CMV) serostatus as a risk factor for survival and treatment-related mortality (TRM) in 125 patients allografted from an unrelated donor between 1994 and 1999. All patients received pretransplant in vivo T-cell depletion using rabbit anti-thymocyte globulin (ATG). Only one patient had primary graft failure and severe grade III/IV graft-versus-host disease occurred in 14% of the patients. The overall survival (OS) at 3 years was 70% for CMV-negative patients (n = 76) and 29% in the seropositive cohort (n = 49) (P > 0.001). In multivariate analyses, CMV seropositivity remained an independent negative prognostic factor for OS (RR: 2.1; CI: 1.2-3.8; P = 0.014), apart from age > 20 years (RR: 2.74; CI: 1.2-3.8; P = 0.004) and late leucocyte engraftment (RR: 2.4; CI: 1.2-4.9; P = 0.015). The TRM for all patients was 27%. Despite monitoring for CMV antigenaemia and preemptive therapy with ganciclovir when reactivation occurred, seropositive patients had a three times higher risk of fatal treatment-related complications than seronegative patients. In multivariate analyses, CMV seropositivity remained the strongest independent negative factor for TRM (RR: 5.3; CI: 1.9-14.6; P = 0.002), followed by age > 20 years (RR: 4.8; CI: 1.3-18.1; P = 0.02) and delayed leucocyte engraftment (RR: 3.6; CI: 1.2-11; P = 0.02). The TRM was identical in seropositive patients with (n = 27) or without (n = 22) CMV reactivation (44% versus 50%). We conclude that CMV seropositivity, despite preemptive ganciclovir therapy and even without reactivation, is a major negative prognostic factor for survival as well as for TRM in unrelated stem cell transplantation using pretransplant in vivo T-cell depletion with ATG.

Abstract
Y chromosome-specific sequences can be used to detect remaining male cells after sex-mismatched allogeneic blood stem cell transplantation (HSCT) involving a male patient and female donor, which represents approximately 25% of all cases. We developed a quantitative Y chromosome-specific PCR assay (QYCS-PCR) based on the DFFRY gene for the determination of hematopoietic donor chimerism. We analyzed blood and marrow samples from more than 40 patients at various time points after both standard and nonmyeloablative allogeneic HSCT. We found that real-time PCR combines extreme sensitivity, with a detection level of less than 1 male in 100,000 female cells (<0.001%), with very good reproducibility, especially in the important range of minor host chimerism. QYCS-PCR results were in close agreement with data from other techniques as bcr/abl-PCR and/or fluorescent in situ hybridization (FISH) analysis. In two relapsed patients, increasing numbers of Y-positive hematopoietic cells indicated recurrence of malignant disease prior to clinical confirmation. In conclusion, quantitative Y chromosome-specific PCR is a promising approach for monitoring the extent of chimerism in blood and other tissues after sex-mismatched hematopoietic stem cell transplantation (HSCT) or organ transplantation.

Abstract
To reduce the incidence of GvHD and the rate of graft failure in unrelated stem cell transplantation, we incorporate anti-thymocyte globulin in the preparative regimen in 98 patients with hematological or inherited storage disease. The median age was 32 years (range: 1-56) and 84 patients underwent transplantation from HLA-A,-B and DR identical donor, while in 14 patients the donor were mismatched either in HLA- A, -B or -DR locus. Only one patient with chronic myelocytic leukemia (CML) and blast crisis had a primary graft failure (1%). Grade II-IV acute GvHD occurred in 37 patients (37%), grade III/IV GvHD developed in 15 patients (15%). Chronic GvHD was observed in 29%, and only 12 patients had extensive GvHD (17%). After a median follow-up of 34 months (range, 9-90), the estimated overall survival at 3 years for all patients is 58% (CI 95%: 48%-68%), and the estimated disease-free survival at 3 years is 49% (CI 95%: 38%-60%). For patients with CML transplanted in first chronic phase or accelerated phase (n=40), the estimated overall survival at 3 years is 70% (CI 95%: 56%-84%), and the estimated disease-free survival at 3 years is 58% (CI 95%: 17%-85%). ATG in unrelated stem cell transplantation reduces the risk of severe acute and chronic GvHD and of graft failure without an obvious increase of severe infection. Further follow-up is mandatory to determine the incidence of late relapse.

Abstract
We compared fractionated total body irradiation (12 Gy)/cyclophosphamide (120 mg/kg) with busulfan (16 mg/kg)/cyclophosphamide (120 mg/kg) as preparative therapy in unrelated donor stem cell transplantation of CML patients. Fifty patients with CML (1.CP = 46; aP = 4) and a median age of 36 years (range 16-52) were enrolled in this sequential trial between 1994 and 1999. In both groups patients were well balanced with respect to age, disease status, stem cell source and CMV status. All patients received standard doses of cyclosporin A, methotrexate and anti-thymocyte globulin (ATG) as GVHD prophylaxis. No graft failures occurred in either group. The median day of leukocyte engraftment was earlier in the Bu/Cy than in the TBI/Cy group (day 15 vs 17; P = 0.006). The incidence of grade II-IV GVHD was 40% in the TBI/Cy and 36% in the Bu/Cy group, whereas severe grade III/IV GVHD was only observed in 12% of patients in both groups. The incidence of chronic GVHD (limited and extensive) at 1 year was higher in the Bu/Cy arm (65% vs 30%; P = 0.02). More toxicity grade I/II of the liver (88% vs 44%; P = 0.002) and more hemorrhagic cystitis (32% vs 8%; P = 0.02) were observed in the Bu/Cy regimen. Seven relapses in the TBI and no relapse in the Bu/Cy group were observed after a median follow-up of 44 and 15 months, respectively. The estimated 3 year OS and DFS was 72% (95% CI: 55-98%) and 58% (95% CI: 39-77%) in the TBI and 70% (95% CI: 51-89%) for DFS and OS in the Bu/Cy group. We conclude that the anti-leukemic effect of the Bu/Cy regimen seems to be at least as effective as the TBI/Cy combination in unrelated stem cell transplantation of CML patients, with no graft failures, but that it correlates with a higher incidence of liver toxicity, hemorrhagic cystitis and chronic GVHD. Longer follow-up is necessary to determine the late relapse rate and late toxicity.

Abstract
Simian virus 40 (SV40) is a dsDNA polyomavirus that induces osteosarcomas and mesotheliomas in hamsters and transforms many types of cells in tissue culture, including human cells. Osteosarcoma is a bone malignancy with multiple molecular lesions underlining progression from normal bone to osteosarcoma. Recent investigations have identified SV40 DNA sequences in osteosarcomas, suggesting that SV40 may contribute to tumor development. However, these studies also demonstrated that geographical differences exist between SV40 and tumor association. Our study analyzed 46 frozen German tumor specimens (42 osteosarcomas and 4 sarcomas initially suspected to be osteosarcomas) for the presence of SV40 DNA sequences by using PCR. Two different primer sets amplifying a 573 bp region of SV40 Tag gene with the complete intron sequence (SV.for 2/SV.rev) and a 172 bp region with no intron sequence (SV.5/SV.6) were used. DNA sequencing analysis verified the results. No SV40 sequences could be detected using the primer set SV.for 2/SV.rev, while 2 out of 42 osteosarcoma specimens and 1 out of 4 poorly-differentiated tumor specimens contained SV40 sequences, using the primer set SV.5/SV.6. From one of these two positive osteosarcomas, multiple tumor biopsies taken at different times during the dissection, including metastasis, tested positive for SV40. These results indicated that in Germany, only rare osteosarcomas can be linked to SV40. These results support previous findings involving geographical differences in the presence of SV40. Finally, the specific detection of SV40 sequences with multiple specimens from one of the two patients and the absence of SV40 sequences in all other samples underscores the specificity and reproducibility of this investigation and ruled out PCR contamination.

Abstract
To evaluate the efficacy and toxicity of two different etoposide (VP-16) dosages (30 or 45 mg/kg) in combination with busulfan/cyclophosphamide as conditioning therapy followed by stem cell transplantation in acute myeloid leukemia (AML), 90 patients with AML received either 30 mg/kg (n = 60) or 45 mg/kg (n = 30) etoposide in combination with busulfan (16 mg/kg) and cyclophosphamide (120 mg/kg). The stem cell source was allogeneic related bone marrow (BM) (n = 53), allogeneic unrelated BM (n = 5), allogeneic unrelated peripheral blood (PBSC) (n = 2), syngeneic BM (n = 2), autologous BM purged (n = 9) or unpurged (n = 9), autologous PBSC (n = 10). Fifty-six patients (62%) were in first CR, 26 (29%) were > first CR, and eight (9%) were transplanted in relapse. Principal toxicities in both groups were mucositis and hepatotoxicity. Forty-five mg/kg etoposide resulted in greater hepatic toxicity (P = 0.03), and a higher incidence of VOD (23 vs 12%, P = 0.04) and acute GVHD grade III/IV (13 vs 5%, NS). The treatment-related mortality was 17% in the 30 mg/kg group and 33% in the 45 mg/kg group, mainly due to infections, intestinal pneumonia and GVHD. Hematological recovery of leukocytes 1/nl was comparable in both groups (17 vs 16 days). After a median follow-up of 16 months 19% in the 30 mg/kg group and 23% in the 45 mg/kg group relapsed. In patients who had undergone allogeneic related bone marrow transplantation in first CR no relapses occurred after a median follow-up of 3 years. For all patients the 3-year estimated disease-free survival was 62% in the 30 mg/kg group and 40% in the 45 mg/kg group (P = 0.03). For patients in first CR who underwent allogeneic related stem cell transplantation the 3 year disease-free survivals were 80% and 66%, respectively (P = 0.4). We conclude that etoposide 30 mg/kg or 45 mg/kg in combination with busulfan/cyclophosphamide is a highly active regimen for bone marrow transplantation of patients with AML with a low relapse rate. However, conditioning with 30 mg/kg rather than 45 mg/kg etoposide resulted in less toxicity and a better overall survival due to a lower transplant-related mortality.

Abstract
UNLABELLED The detection of minimal residual disease (MRD) is a major prognostic factor for treatment in acute lymphoblastic leukemia (ALL) of childhood. Several groups showed the predictive value of MRD after 5 weeks of chemotherapy (at the end of induction therapy). Patients with more than 1 leukemic cells in 100 cells (> or = 10(-2)) at this time-point have a significantly higher relapse rate. The MRD measurement has been shown to be an independent prognostic factor at several time points in the BFM study (ALL-BFM 90) as well as in the EORTC study. The aim of our investigations was the detection of MRD at the end of induction therapy within the COALL studies which is different from the above studies. In the COALL studies, therapy starts with a 1 week DNR prephase (24 h infusion on day one) and i.th. MTX. Induction therapy consisted of 3 drugs over a period of 4 weeks (Prednisolone, Vincristine and Daunorubicin), asparaginase is given later in consolidation. At the end of induction therapy, bone marrow was obtained for cytomorphologic and molecular analysis. PATIENTS AND METHODS We investigated bone marrow samples from 76 patients. All patients were in morphologic remission at the end. of induction therapy. For MRD analysis, DNA was isolated from bone marrow mononuclear cells. Clonal T-cell-receptor (TCR) or immunoglobulin gene (IgH) rearrangements were identified by PCR. Monoclonal products were either sequenced directly (TCR) or after excision from high resolution agarose gels. Subsequently patient-specific oligonucleotides for allele-specific PCR were generated. PCR analysis was performed with 1 microgram DNA for each reaction within a semiquantitative matter. This method reached sensitivities down to 10(-5). RESULTS Eighty-four percent of the analysed samples were MRD positive at the end of induction therapy. 20 out of 76 patient samples (26%) were highly positive (> or = 10(-2)), 28 patients had levels of about 10(-3) (37%), 16 had levels around 10(-4) (21%) and 12 patients had no detectable residual cells (16%). All analysed 15 T-ALL patients had detectable residual disease at this timepoint. Until now, 5/20 patients with very high MRD level at the end of induction therapy suffered a relapse. DISCUSSION Patients with very high MRD level at the end of induction therapy showed an elevated risk of relapse, but the predictive value is much poorer than for example in the BFM 90 MRD-study. We suggest, that a high MRD level at this timepoint results from a different induction therapy compared to the BFM 90 study. In the COALL studies asparaginase is given only after induction therapy to decrease the risk of thrombosis. We would like to conclude that this differences were compensated later during therapy as the event free survival of both studies is similar. In conclusion, an optimal information from MRD studies is strongly associated with the given therapy. Therefore we initiated an additional MRD time-point after the first chemotherapy block in consolidation.

Abstract
BACKGROUND Idarubicin (IDR) is one of the most effective, but also toxic drugs in the treatment of AML. The standard dose used in children and adults is 8-12 mg/m2 during induction. PATIENTS AND METHODS To improve outcome, we increased the IDR dose from 12 mg/m2 (standard dose in study AML-BFM 93), applied over three days during induction therapy (AIE = Ara-C, Idarubicin, Etoposide) to 14 mg/m2 in a pilot study including 17 patients (16 with de novo AML, one with secondary AML). Outcome and toxicities were compared with the other patients of study AML-BFM 93, treated with 3 x 12 mg/m2 IDR or 6 x 30 mg/m2 daunorubicin (DNR). RESULTS Patients of the pilot study achieved a good blast cell reduction in the bone marrow on day 15, a high CR rate of 94% and a low relapse rate (3/17 pts.), however, not significantly different to the IDR (12 mg/m2) group. Hematological toxicity was high, median duration until neutrophil recovery > 500/microliter was 25.0 (12-66) days, and similar to the IDR (12 mg/m2) and DNR groups. Duration of thrombocytopenia (time to > 20,000/microliter) was 21 (10-66) days in the pilot study compared to 19 (7-26) days in DNR patients (p = 0.08). Four of 17 pilot patients presented with severe WHO grades 3/4 of mucositis during induction. One patient died in long-lasting aplasia after the 3rd treatment block. CONCLUSION Results of this pilot study show that the IDR 14 mg/m2 regimen was effective but also toxic. According to our results which, however, are based on small patient numbers, an improved outcome compared to the IDR 12 mg/m2 regimen seems to be unlikely, therefore the possibly increased toxicity might not be acceptable.

Abstract
Haemophagocytic lymphohistiocytosis (HLH) is an autosomal recessive disease with histiocytic and lymphocytic infiltrations in multiple organs. Cure seems possible only by allogeneic bone marrow transplantation (BMT), but matched sibling donors (MSD) are restricted and high mortality rates are associated with BMT from unrelated donors (URD). We report on 12 consecutive HLH patients with an improved outcome following URD transplants. Eight patients received BMT from URD, four from MSD. Five patients had signs of active HLH at the time of BMT. The conditioning regimen consisted of 20 mg/kg busulphan, 60 mg/kg VP-16 and 120 mg/kg cyclophosphamide and, in case of URD, 90 mg/kg antithymocyte globulin. The doses of busulphan and VP-16 were reduced during the programme to 16 mg/kg and 30 mg/kg, respectively. Using a fivefold graft-versus-host disease (GVHD) prophylaxis, GVHD was absent or mild in 10, and moderate or severe in two patients undergoing unrelated transplants. One patient with URD experienced graft failure and was retransplanted on day 37. Major toxicities were hepatic veno-occlusive disease in five, capillary leak syndrome in two, pneumonia in three, sepsis in one, severe mucositis in one and seizures in two patients. All patients are alive without HLH after a median follow-up of 24.5 months. One patient has chronic GVHD, another patient has severe retardation. Three patients show slight to moderate development delay. These results indicate that in HLH, BMT from matched unrelated donors should be performed. Incomplete resolution of disease activity need not impede a successful outcome.

Abstract
A five-agent GVHD prophylaxis programme consisting of cyclosporin A, methotrexate, anti-thymocyte-globulin, pentaglobin and metronidazol was given to 48 recipients of unrelated donor marrow with chronic myelogenous leukemia, acute leukemia, myelodysplastic syndromes, and familiar lymphocytic hemophagocytosis of an average age of 33.5 (0.6-56) years. GVHD grades II-IV occurred in 18 patients (39%) and grades III-IV in five patients (11%). Chronic GVHD developed in nine patients (23%), three limited and six extensive. Fifteen patients died. Clinical relapse was detected in eight patients. Four patients died as a consequence of the underlying disease and subsequent treatment, 11 patients died of transplant-related causes. After a median follow-up of 19 months, the overall and disease-free survival are 67% and 62%, respectively. Survival by age is as follows: 0-19 years: 12/13 patients; 20-39 years: 14/25 patients; 40-59 years: 7/10 patients. The five-agent GVHD prophylaxis regimen is effective. Matched-unrelated donor transplants can be carried out safely in patients younger than 50 years of age. The results in patients younger than 20 years of age should encourage matched-unrelated donor transplants at earlier stages of the disease.

Abstract
Infections are a major cause of morbidity and mortality in patients undergoing high-dose therapy and subsequent autologous or allogeneic haemopoietic stem cell transplantation, despite the change from topical to systemic anti-infection prophylaxis and the introduction of growth factors and new antimicrobial drugs. We report our single centre experience with data from 409 patients treated at our unit from its opening in 1990 until May 1997. Three hundred and seventy-eight patients were transplanted for the first time, 12 patients were retransplanted or boosted and 19 patients were readmitted for miscellaneous reasons. 245 patients were allografted and 157 autografted. Antimicrobial prophylaxis was mainly quinolones, fluconazole plus amphotericin-B orally, aciclovir, and TMP/SMX or pentamidine. Three hundred and nineteen (78%) developed fever of significantly longer duration in the allogeneic setting with anti-CMV seropositivity. The most frequent infection was fever of unknown origin (50.6%), followed by septicaemia (12.5%) and pneumonia (11.0%). Pathogens isolated in 24.6% of the infections were mostly gram-positive bacteria (57.9%), followed by non-fermenting rods (11.2%), Aspergillus spp. and Candida spp. (10.3%, each). Cumulative response rate to antimicrobial therapy was 66.9%. Infections were responsible for 62.5% (25/40) of deaths after transplantation. Predominant pathogens were Aspergillus spp. (11), Candida spp. (four), and Pseudomonas spp. (three). None of the patients died from gram-positive bacterial infection. The risk of dying from infection was 11.2% after allografting and 0.8% after autotransplantation. Infections remain a major risk for early death after allogeneic transplantation of haemopoietic stem cells. Infection with gram-negative bacteria can be prevented by quinolone prophylaxis. Predominant pathogens are Aspergillus spp. Candida spp. and nonfermenting rods. Systemic infection with these pathogens is associated with a poor prognosis. Antimycotic prophylaxis and the therapy must be improved.

Abstract
115 patients undergoing allogeneic or autologous bone marrow or peripheral blood stem cell transplantation were treated empirically or for documented fungal infection with liposomal amphotericin-B in doses up to 10mg/kg bodyweight for a duration up to 61 days. The therapy was excellent tolerated and clinical side effects occurred in only eight patients. The drug had to be withdrawn in one episode. A significant influence of liposomal amphotericin-B on laboratory parameters was not observed. Creatinine increased under therapy from a median base point of 1,0 (0,2-3,5) mg/dl to the upper normal value of 1,4 (0,4-4,2) mg/dl. Heavy increases of creatinine as well as of bilirubin, OT and PT were mostly associated with GvHD or regimen related toxicity. Considering the high-risk state of the patients the overall response rate was favourable with 62,9%. However, despite administration of liposomal amphotericin-B culture-proven mycoses were associated with a high morbidity (93,3%). Only one of fourteen patients was cured from Candida lambica septicaemia. We conclude that the antimycotic therapy with liposomal amphotericin-B has a low incidence of side effects. This should, considering the high mortality of fungal infections in BMT recipients, encourage investigators to perform dose escalating studies against the conventional formulation.

Abstract
We investigated an intensified conditioning regimen including fractionated total body irradiation (12 Gy), etoposide (30-45 mg/kg) and cyclophosphamide (120 mg/kg), followed by autologous (n = 5), allo-related (n = 13) or allo-unrelated (n = 6) bone marrow (n = 22) or peripheral stem cell (n = 2) transplantation in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia. One patient received busulfan (16 mg/kg) instead of TBI. Nineteen patients were transplanted in 1CR, two in 2CR, one in 1PR and two in relapse. Major toxicity was mucositis grade II according to the Bearman scale in all patients. The treatment-related mortality was 25%, mainly due to infection or GVHD after allogeneic transplantation. After a median follow-up of 45 months (range 2-93), nine patients (37.5%) remain alive in CR. Nine patients (37.5%) relapsed and eight (33.3%) of these subsequently died. After autologous transplantation, four of five patients (80%) relapsed and died. Late relapse was seen after allogeneic, as well as autologous transplantation, at 33 and 59 months, respectively. The Kaplan-Meier estimate of leukemia-free survival for all patients is 38% at 3 years (95% CI: 18-58%) and 35% at 5 years (95% CI: 15-55%). For allogeneic transplants in first CR (n = 15) the estimate of disease-free survival was 46% at 3 years (95% CI: 19-73%) and 34% at 5 years (95% CI: 17-51%). Patients aged below 30 years had a better estimated overall survival at 3 years (61% vs 11%, P < 0.001). The bcr-abl fusion transcript (p210 vs p190 vs p210/190) did not affect disease-free or overall survival. In our experience, an intensified conditioning regimen seems to improve the results of bone marrow transplantation in patients with Ph+ acute lymphoblastic leukemia. However, the high relapse rate warrants novel approaches to enhance anti-leukemic efficacy.

Abstract
Between January 1986 and May 1996, 870,313 children were tested in European neuroblastoma (NB) screening programmes. Among these children, 82 cases of NB (age range 4-24 months, median 11 months) were detected by screening. 83% of the patients had localised NB and 17% were diagnosed with generalised NB (stage 4, 10%; stage 4s, 7%). Unfavourable biological markers (MYCN amplification, loss of heterozygosity (LOH) 1p36, DNA di/tetraploidy) were observed in 14% of 76 biologically examined cases. The median follow-up time of all the patients was 21.5 months (range 1-101 months). To date, 69 patients are in complete remission (CR) and 2 patients have died due to therapy (stage 4, 1 patient; stage 3, 1 patient with unfavourable markers). Apart from screened patients, 16 other patients with NB were found who had previously had a normal screening test, i.e. 'false negative' patients (age range 10-41 months, median 31.5 months). The median interval between screening and diagnosis was 24.5 months (range 6-35 months). 11 of the 'false negative' patients suffered from generalised NB (stage 4) and 5 had localised NB at diagnosis. Unfavourable biological markers were observed in 7/12 patients. 5 patients have died, 2 achieved partial remission and 9 CR. 9 of the 11 patients with unfavourable biological markers diagnosed due to NB screening are currently in CR. It is very likely that, among the patients without unfavourable biological markers, we detected tumours which may have regressed spontaneously. These children may have undergone 'unnecessary,' but unavoidable, diagnostic procedures and therapy. To reduce the number of 'false negative' patients, a later screening could be helpful and should be evaluated.

Abstract
Relapse after transplant for malignant lymphomas remains the main cause of treatment failure. Most conditioning regimens contain total body irradiation (TBI). We investigated the toxicity and efficacy of an intensified chemotherapy conditioning regimen without TBI in patients with relapsed or high-risk malignant lymphoma who had received prior radiation therapy and were therefore not eligible for TBI. Twenty patients with a median age of 38 (18-56) and relapsed or high-risk malignant non-Hodgkin's lymphoma (NHL, n = 16) or Hodgkin's disease (HD, n = 4) underwent high-dose chemotherapy consisting of busulfan (16 mg/kg), cyclophosphamide (120 mg/kg) and etoposide 30 mg/kg (n = 8) or 45 mg/kg (n = 12) followed by peripheral stem cell support (n = 14), autologous bone marrow (n = 3), allogeneic (n = 2) or syngeneic (n = 1) transplantation. All but two had chemosensitive disease before high-dose chemotherapy. The main toxicity -- according to the Bearman score -- was mucositis II in 18 (90%) patients; five patients (25%) suffered a grade I hepatic toxicity. GI toxicity I occurred in three (15%) and renal toxicity I in two patients (10%). Sixty percent of the patients developed transient dermatitis with erythema and three of them (15%) had skin desquamation; one patient experienced asymptomatic pancreatitis. Toxicity was slightly higher in patients treated with 45 mg/kg etoposide. One patient (5%) died of treatment-related venoocclusive disease. After a median follow-up of 50 months (24-84) the disease-free and overall survival were 50% and 55%. One of the nine relapsing patients developed secondary AML 18 months after transplant. High-dose busulfan, cyclophosphamide and etoposide is an effective regimen resulting in long-term disease-free survival in 50% of patients with relapsed malignant lymphoma and prior radiation therapy. The toxicity is moderate with a low treatment-related mortality (5%).

Abstract
We explored the combination of busulfan/cyclophosphamide/etoposide as conditioning regimen prior to bone marrow transplantation in 31 patients with acute myeloid leukemia (AML) in first complete remission. The preparative regimen consisted of 16 mg/kg busulfan, 30-60 mg/kg VP-16, and 120 mg/kg cyclophosphamide. With a median follow-up of 30.5 months (range, 5-60 months), 25 patients are alive in continuous complete remission. Estimated disease-free survival at 5 years is 80.5%. Death was due to transplant-related toxicity (graft-versus-host disease and cytomegalovirus infection, graft-versus-host disease and pneumonia, sepsis and mucositis, respectively). None of the patients have relapsed. As demonstrated by the results of this analysis, the conditioning regimen busulfan/cyclophosphamide/etoposide is effective and well tolerated in patients with AML in first complete remission. Main nonhematological toxicities were mucositis and hepatotoxicity. The low mortality and relapse rate appears to justify allogeneic bone marrow transplantation for patients with AML in first complete remission who have an HLA-identical donor. Whether this regimen offers a substantial improvement in disease-free and overall survival over presently used regimens warrants further investigation.

Abstract
Rearrangement of the tal-1 gene is the most frequent clonal marker in childhood T cell acute leukemia. Previously, tal-1 mRNA expression has been observed only in cells of the erythroid, mast cell, and megakaryocytic lineages and in blastic lymphoid cells of normal bone marrow, not in normal lymphocytes or monocytes of the peripheral blood (PB). In this study we addressed the question of tal-1 expression during normal hematopoietic development by performing reverse transcription-polymerase chain reaction (RT-PCR) on RNA from PB cells of 12 healthy donors. Ten of 10 unsorted samples were RT-PCR positive for tal-1 expression. Sorted T cells and monocytes from three donors showed tal-1 RT-PCR products. This is the first direct experimental evidence of tal-1 transcripts in these two normal PB cell types.

Abstract
Myelodysplastic syndrome (MDS) in childhood is considered to be very rare and detailed pathobiological data are scarce. More biological information regarding MDS in children is clearly needed and in vitro culture studies provide one possibility for gaining further pathophysiological insights into this malignancy. Here, we incubated bone marrow samples from 30 children with MDS in liquid suspension culture in order to grow the transformed cells in vitro. In most cultures, the hematopoietic cells died quickly and only fibroblastic (stromal) background layers proliferated temporarily; several normal Epstein-Barr virus (EBV)-transformed B-lymphoblastoid cell lines (B-LCL) were established. Only in one instance, albeit from the peripheral blood and not from the bone marrow, could we establish a cell line, termed MUTZ-1, from the malignant cells of a 5-year-old girl with MDS (FAB subtype refractory anemia with excess of blasts). The MDS arose from a pre-existing Fanconi anemia and progressed quickly to an acute myeloid leukemia (FAB M2). Despite positivity for EBV, MUTZ-1 is not an EBV + B-LCL and further characterization of MUTZ-1 confirmed the derivation from the transformed clonal cells. Immunophenotyping showed a pre B-cell surface marker profile (CD10+ CD19+ cytoplasmic IgM+); receptor gene rearrangement analyses underlined the clonal B-cell nature of MUTZ-1 cells. MUTZ-1 cells exhibit a highly rearranged, unstable karyotype with a high frequency of spontaneous chromatid breaks and exchanges; del(5q) and additional rearrangements involving chromosome 5 [der(15)t(5;15)] were detected. The present data and results from a few other MDS-derived cell lines suggest that the transforming event in MDS seems to occur in an immature pluripotent progenitor cell. The new MDS-derived continuous cell line MUTZ-1 provides a useful in vitro model system for studies on the pathogenetic events leading to MDS.

Abstract
We report the outcome of eight patients with different hematological malignancies who were transplanted with allogeneic CD34-selected mononuclear cells following myeloablative therapy. Four patients received G-CSF mobilized CD34-enriched peripheral blood progenitor cells (PBPC) together with CD34-enriched bone marrow (BM), two patients were transplanted with allogeneic G-CSF mobilized CD34-enriched PBPC alone, and two patients received only allogeneic CD34-enriched BM cells. On average, patients received 2.66 x 10(6) CD34+-cells/kg BW (range: 0.53-8.40 x 10(6) CD34+-cells/kg body weight) and 0.57 x 10(6) CD3+-cells/kg BW (range: 0.20-1.10 x 10(6) CD3+-cells/kg BW), respectively. Seven of the eight patients engrafted (ANC > 0.5 x 10(9)/L median: day +19 (range: 16-23 days); platelets > 20 x 10(9)/L median: day +34 (range: 21-47 days); one patient died on day +16 after transplantation and was not evaluable for engraftment. Three of seven patients evaluable for acute graft-versus-host disease (GvHD) developed acute GvHD grade II which resolved upon steroid treatment. Five of the eight patients are still alive and in remission with a median follow-up of 215 days (range: 80-420 days). Causes of death included fungal infection, cerebral bleeding and sepsis. These preliminary data suggest that CD34-enriched cells can be successfully given during for allogenic transplantation following myeloablative therapy in hematological malignancies. The impact of T-cell depletion by enrichment for CD34+-cells in an attempt to reducing the incidence and/or severity of acute and/or chronic GvHD still remains to be determined.

Abstract
Rearrangement of the gene tal-1 leads to transcriptional dysregulation and contributes to the formation of childhood T-cell acute lymphoblastic leukemia. Therefore, we tried to interfere with the transcription of the SIL/tal-1 fusion gene, the most common form of aberrant tal-1, by treatment with antisense oligodeoxynucleotides (ODNs). The potential of two different strategies was investigated, one targeting the cell line specific SIL/tal-1 fusion region, the other using an ODN complementary to tal-1 sequence downstream of the region not affected by any of the known types of tal-1 rearrangement. With both approaches a single-dose application of 3 mumol of ODN led to a significant antiproliferative effect of a about 25-60% in two T-ALL cell lines characterized by the SIL/tal-1 fusion gene. Investigation of the tal-1 mRNA level by reverse transcription-polymerase chain reaction was in concordance with these results: In both cell lines clearly less of the tal-1-specific fragment was generated after incubation with the antisense ODN tal-1 common than in the control experiments with a mismatched ODN or no ODN at all. Neither the antiproliferation antisense effect nor the downregulation of the steady state tal-1 mRNA level was observed in control cell lines bearing wildtype tal-1.

Abstract
We have previously shown that allogeneic bone marrow transplantation (BMT) with cryopreserved donor marrow cells can be used without prolonging the engraftment time or interfering with the reconstitution of haemopoiesis. In this report we extend our initial observations of the first 40 patients who underwent allogeneic bone marrow transplantation from related donors with cryopreserved donor bone marrow for haematological malignancies, including the long-term follow-up data of the previously reported patients. The outcome of these patients was compared with that of 40 related BMT recipients receiving fresh donor bone marrow (historic control group). Time until engraftment of all patients receiving cryopreserved bone marrow was not different from the control group (ANC > 0.5 x 10(9)/l 17d (range 11-24 d) versus 17.5 d (range 10-28 d): platelets > 20 x 10(9)/l 21 d (range 11-85 d) versus 22 d (range 13-69 d), respectively). There was the same incidence of acute and chronic GvHD in patients receiving either cryopreserved bone marrow or fresh bone marrow (acute GvHD > or = II 61% v 60% and chronic GvHD 56% v 52%, respectively). Chimaerism studies showed no difference between the patient groups. Furthermore, the two groups did not differ in day 100 survival (82% v 72%). With a median follow-up of 520 d (range 47-1365 d) and 1289 d (range 48-1849 d), 60% of the patients receiving cryopreserved and 53% of the patients receiving fresh allogeneic donor bone marrow, respectively, are alive. We conclude that cryopreservation of allogeneic related donor bone marrow does not adversely affect engraftment, does not decrease the incidence of severe acute GvHD, and does not seem to affect the day 100 survival or long-term haemopoiesis.

Abstract
The 'deleted in colon carcinoma' (DCC) gene has been considered a candidate tumour-suppressor gene that encodes for a transmembrane protein with strong structural similarity to members of the superfamily of neural cell adhesion molecules. It has been mapped to the chromosomal region 18q21.1 and it is implicated in cellular differentiation and developmental processes. In human osteosarcoma allelic loss frequently occurs on the long arm of chromosome 18, suggesting a possible involvement of the DCC gene in the pathogenesis of this tumour entity. In the present study the mRNA and protein expression and rearrangements at the DNA level of the DCC gene were addressed in 25 osteosarcomas and several tumour cell lines, including osteosarcoma- and colon carcinoma-derived cell lines. Using an reverse transcriptase polymerase chain reach in (RT-PCR)-based approach DCC expression was found to be lost or substantially reduced in 14 of 19 high-grade osteosarcomas, in three of six lower grade osteosarcomas and most of the tumour cell lines, in contrast to normally differentiated osteoblasts. Immunohistochemical studies on DCC protein expression of 14 selected tumours correlated well with the RT-PCR-based results. In view of the putative tumour-suppressor characteristics of the DCC gene its loss or reduction of expression could be a specific event in the development or progression of many high-grade osteosarcomas.

Abstract
A variety of oncogenes are activated by specific chromosomal translocations, which are associated with distinct subtypes of leukemia. The identification of these rearrangements provides critical diagnostic and prognostic information, which may contribute to the selection of specific anti-leukemic therapy. The translocation t(9;22), the equivalent of the BCR/ABL rearrangement, is associated with a poor prognosis. We therefore used RT-PCR to detect this molecular event in a prospective study including 890 children. 673 of them suffered from acute lymphoblastic leukemia (ALL) at primary diagnosis and a transcription of the chimeric gene was detected in 21 of 648 with a successful analysis (3.2%). All children were treated by one of the two German multicenter childhood ALL therapy studies ALL-BFM-90 or COALL-05-92, respectively. Comparison of clinical features between BCR/ABL-positive and -negative children showed no significant differences regarding WBC, percentage of blasts, splenomegaly, hepatomegaly and age. Immunophenotypic studies at diagnosis in 21 BCR/ABL-positive children identified common ALL in 16 patients (76.2%), pre-B-ALL in four (19.0%), and an early T-lineage ALL in one (4.8%). Coexpression of myeloid antigens (CD13 and/or CD33) was observed in six of 16 common ALL patients as well as in the one child with early T-lineage ALL phenotype. The type of breakpoint (m-BCR/ABL: n = 14; M-BCR/ABL: n = 7) showed no correlation with clinical parameters. A comparison of cytogenetic and molecular data was performed in 16 positive patients and was concordant in all of them. We analyzed the response to the prednisone pretreatment and found a higher incidence of poor responders among the BCR/ABL-positive children. Regarding the event-free survival (EFS) of BCR/ABL-positive (0.53) and -negative patients (0.79) after a follow-up of 2 years, significant differences (P < 0.05) between both groups could be demonstrated.

Abstract
To elucidate the events leading to a unique complex translocation involving chromosomes 11, 18, and 19 in a congenital progenitor B-cell acute lymphoblastic leukemia, we have performed comprehensive cytogenetic and fluorescence in situ hybridization (FISH) analyses as well as molecular genetic studies on the DNA and RNA level. We were able to confirm the cytogenetic interpretation of this complex t(11;18;19)(q23;q22;p13.3) by chromosome painting. Involvement of the MLL gene on 11q23 became evident by Southern blot analysis as well as by FISH with a YAC clone containing the respective gene. Despite the fact that the additional signals of the split YAC clone were observed on the abnormal chromosome 18, reverse transcription polymerase chain reaction (RT-PCR) revealed a MLL/ENL hybrid mRNA, which is specific for a t(11;19)(q23;p13.3). This gene fusion most probably represents the critical part of this rearrangement. The transfer of the translocated part of the split YAC clone onto chromosome 18 indicates that the second break must have occurred in the vicinity of the first one, at a distance too close to be resolved by FISH. Whether this break took place within chromosome 11 or 19 sequences, up- or downstream of the MLL/ENL fusion, and whether this translocation results from a concerted simultaneous exchange of material or from two separate sequential events in consecutive cell generations remains open.

Abstract
G-CSF (filgrastim) can effectively mobilize peripheral blood progenitor cells (PBPC) when administered during steady-state hematopoiesis. In this single center study, we compared the effectiveness of two different doses of G-CSF on the mobilization of peripheral blood stem cells in patients with Hodgkin's disease, non-Hodgkin's lymphoma, and cancer of the testis. A first group including 33 patients received 10 micrograms G-CSF/kg BW per day (group A), whereas a second group comprising 34 patients was treated with 24 (2 x 12) micrograms G-CSF/kg body weight (BW) per day (group B) prior to the leukapheresis. A significant difference (P = 0.015) in the total number of CD34+ cells between group A: 11.32 x 10(7) (range 0.34-110.2) and group B: 48.25 x 10(7) (range 1.33-447.4) has been observed in the first leukapheresis product. Moreover, the total number of CFU-GM increased significantly from 34.79 x 10(4) (range 1.07-300.9) to 147.69 x 10(4) (range 1.03- 1204.0) (P < 0.005), and the number of MNC increased from 1.35 x 10(10) (range 0.41-3.09) group A) to 2.93 x 10(10) (range 0.66-9.7) (group B) (P < 0.001). Comparable results were obtained in the second leukapheresis. Our data indicate, that the application of higher doses of G-CSF can significantly improve the effectiveness of mobilizing PBPC during steady-state conditions, and thereby considerably contribute to a safe and fast engraftment as well as a reduced number of leukapheresis procedures to achieve sufficient number of PBPC.

Abstract
In recent years, high dose chemotherapy followed by bone marrow rescue has been established as a common treatment of hematologic and solid tumor malignancies. Despite unequivocal success, relapse after transplant remains a serious problem, being the main cause of treatment failure. In an attempt to reduce relapse rates, we intensified the conditioning regimens consisting of busulfan/cyclophosphamide versus fractionated total body irradiation (f-TBI)/ cyclophosphamide by the addition of high dose etoposide. Toxicity profiles of 25 pediatric patients with hematologic malignancies undergoing intensified conditioning did not differ significantly between the two groups, except for a higher incidence of veno-occlusive disease in busulfan-treated patients (3 of 13 patients) compared with the TBI group (0 of 12 patients). We observed no transplant-related mortality in neither group. Regimen-associated morbidity was moderate and reversible in all cases. Five patients died in each treatment arm, due to relapse of the underlying disease. We conclude that both regimens are feasible in marrow transplantation of pediatric patients. Open randomized trials are needed to assess the efficacy of intensified conditioning in terms of disease-free survival.

Abstract
The time it takes to harvest bone marrow before transplantation could be reduced significantly by increasing the temperature of the operating room by 8-10 degrees C, to about 28-30 degrees C. In healthy donors, the collected volume of marrow was increased from 22.45 to 36.31 mL/min; in patients who received chemotherapy previously, from 21.67 to 29.98 mL/min. The time to collect a volume of 1200 mL marrow could be reduced significantly, from 57.78 to 38.25 minutes in healthy donors and from 71.07 to 43.36 minutes in patients who received chemotherapy previously, without any loss of quality of the sampled marrow. Operation time and thereby time of anesthesia could be reduced significantly by heating the operating room to a temperature of 28-30 degrees C. Harvesting at higher room temperature did not result in any adverse side effects for the patients. The procedure to increase the body temperature could be simplified by using electric blankets and aluminum foils for wrapping to avoid heat emission.

Abstract
Many approaches have been taken to reducing the rate of graft failure and the incidence of graft-versus-host disease (GVHD) in bone marrow transplantation (BMT) of patients with severe aplastic anemia (SAA). The combination of cyclophosphamide with irradiation has had unequivocal success in reconstituting a sustained engraftment, but this procedure has severe associated risks such as second malignancies. Recently, cyclophosphamide (CYC) plus antithymocyte globulin (ATG) has been shown to be an effective alternative to irradiation-based programs in retransplants. Based on these experiences, the current clinical trial was started to prepare patients suffering from SAA for marrow transplantation from HLA-identical siblings with ATG plus CYC. Nine patients have been enrolled into the study so far. They received a total dose of 200 mg/kg CYC and concomitantly 120 mg/kg or 90 mg/kg ATG, followed by cyclosporine plus methotrexate as post-transplantation GVHD prophylaxis. Eight of nine patients survived without any transplant-associated complications; i.e., they had a documented stable engraftment without rejection and without acute or chronic GVHD. One patient died due to an Aspergillus sepsis prior to a definite engraftment. Although our data are preliminary because of the small number of patients enrolled and a follow-up of only 30 months, CYC plus ATG appears to be an effective preparative regimen for BMT in patients with SAA, resulting in a favorable outcome.

Abstract
Use of cryopreserved donor bone marrow may facilitate scheduling of allogeneic bone marrow transplantation (BMT) by affording independence of a fixed time for bone marrow donation. The potential risk of damage to hematopoietic stem cells by cryopreservation resulting in delayed engraftment or graft failure has to be taken into account, however. To address these issues, the outcome of 19 matched related BMT (1992-94) performed with cryopreserved donor bone marrow was analyzed and compared with 19 related BMT (1990-93) receiving fresh donor bone marrow (control group). Time to engraftment of patients receiving cryopreserved bone marrow was not different from the control group (ANC > 0.2 x 10(9)/l 15.5 +/- 3.8 days vs 15.8 +/- 5.0 days; ANC > 0.5 x 10(9)/l 17.3 +/- 4.1 days vs 17.9 +/- 5.0 days, respectively). We did not find the previously described trend toward a lower incidence of acute GVHD in patients receiving cryopreserved bone marrow compared with patients receiving fresh bone marrow (acute GVHD > or = II 78 vs 64%). Furthermore, the two groups did not differ in the incidence of chronic GVHD (55 vs 38%) or day 100 survival (74 vs 68%). We conclude that in allogeneic BMT cryopreserved bone marrow cells can be safely used without jeopardising or prolonging time to engraftment.
