Abstract
Omenn syndrome is a severe combined immunodeficiency characterized by erythroderma, hepatosplenomegaly, lymphadenopathy and failure to thrive, with activated oligoclonal T lymphocytes and an absence of circulating B cells.A 3 day-old boy presented with a congenital erythroderma. Investigations revealed a marked neutropenia and lymphopenia and the absence of a thymus. Genetic studies showed RAG 1 mutations. He was successfully treated with an HLA identical bone marrow transplantation. Omenn syndrome is a rare severe combined immunodeficiency. Most cases are due to mutations in the RAG genes with autosomal recessive transmission. Our observation is original because of an incomplete clinical presentation. During the course of the disease, the child had no failure to thrive, no organomegaly and no recurrent infection. Immunodeficiency must be excluded in every case of neonatal erythroderma and an immunological assessment should be performed without delay.

Abstract
The National Kidney Foundation/Kidney-Dialysis Outcome Quality Initiative guidelines recommend to maintain the serum intact parathyroid hormone (PTH) concentration between 150 and 300 ng/l in chronic kidney disease (CKD) stage 5 patients. As these limits were derived from studies that used the Allegro intact PTH assay, we aimed to evaluate whether they were applicable to other PTH assays. We compared the PTH concentrations measured with 15 commercial immunoassays in 47 serum pools from dialysis patients, using the Allegro intact PTH assay as the reference. We also evaluated the recovery of graded amounts of synthetic 1-84 and 7-84 PTH added separately to a serum pool. Although the assays were highly correlated, the concentrations differed from one assay to another. The median bias between the tested assays and the Allegro intact PTH assay ranged from -44.9 to 123.0%. When the PTH concentrations were 150 or 300 ng/l with the Allegro intact PTH assay, they ranged with other assays from 83 to 323 ng/l and from 160 to 638 ng/l, respectively. The tested assays recognized 7-84 PTH with various cross-reactivities, whereas a given amount of 1-84 PTH was recovered differently by these assays. We found important inter-method variability in PTH results owing to both antibody specificity and standardization reasons. The unacceptable consequence is that opposite therapeutic attitudes may be reached in a single patient depending on the PTH assay used. We propose to use assay-specific decision limits for CKD patients, or to apply a correcting factor to the PTH results obtained with a given assay.

Abstract
The first EORTC (European Organization of Research and Treatment of Cancer) acute myeloblastic leukemia (AML) pilot study (58872) was conducted between January 1988 and December 1991. Out of 108 patients, 78% achieved complete remission (CR), and event-free survival (EFS) and survival rates (s.e., %) at 7 years were 40 (5) and 51% (6%), respectively. It indicated that mitoxantrone could be substituted for conventional anthracyclines in the treatment of childhood AML without inducing cardiotoxicity. The aim of the next EORTC 58921 trial was to compare the efficacy and toxicity of idarubicin vs mitoxantrone in initial chemotherapy courses, further therapy consisting of allogeneic bone marrow transplantation (alloBMT) in patients with an HLA-compatible sibling donor or chemotherapy in patients without a donor. Out of 177 patients, recruited between October 1992 and December 2002, 81% reached CR. Overall 7-year EFS and survival rates were 49 (4) and 62% (4%), respectively. Out of 145 patients who received the first intensification, 39 had a sibling donor. In patients with or without a donor, the 7-year disease-free survival (DFS) rate was 63 (8) and 57% (5%) and the 7-year survival rate was 78 (7) and 65% (5%), respectively. Patients with favorable, intermediate and unfavorable cytogenetic features had a 5-year EFS rate of 57, 45 and 45% and a 5-year survival rate of 89, 67 and 53%, respectively.

Abstract
Extranodal thyroid lymphomatous involvement is rare in childhood. We report here 2 children, 1 with vertical transmission-acquired human immunodeficiency virus (HIV), presenting with lymphomatous infiltration of the thyroid gland at diagnosis. One child had infra-clinical endocrine impairment and both responded well to chemotherapy. Although the cases are too scarce to be affirmative, thyroid gland involvement doesn't seem to alter the good prognosis of childhood Burkitt's lymphoma. The third child's cancer in frequency is Non-Hodgkin Lymphomas. Presenting as the initial AIDS event in 1 patient, this case report also highlights the need to systematically propose antiretroviral therapy in vertically HIV infected children.

Abstract
The purpose of this study was to identify risk factors for hypothyroidism after bone marrow transplantation (BMT) for high-risk or relapsed acute lymphoblastic leukaemia (ALL) in children. In all, 388 children with acute lymphoblastic leukaemia underwent allogeneic bone marrow transplantation between 1984 and 1994. Overall 5-year survival was 54.6%. Thyroid function was assessed in the 153 patients with more than 5 years of follow-up. In total, 16 patients developed uncompensated hypothyroidism (UH) and 46 compensated hypothyroidism (CH) a median of 2.9 and 2.7 years, respectively, after BMT. Thyroid dysfunction-free survival rates were 73.2% after 5 years and 59.2% after 10 years. Three factors were significantly associated with the onset of hypothyroidism, namely age, bone marrow transplantation in second remission, and single-dose total body irradiation (TBI). Ultrasonography of the thyroid showed nodules in 10 of 35 patients. The median time from BMT to nodule detection was 7.8 years. Cytology (n=5) and surgery (n=4) showed no evidence of thyroid cancer. Four of the 14 patients who received cytoreduction without TBI but with busulphan and cyclophosphamide developed UH (n=2) or CH (n=2). We concluded that children who undergo BMT for ALL are at a high risk of subsequent thyroid dysfunction.

Abstract
This cross-sectional study aimed to investigate, during a short period between 2000 and 2001, in a large population of patients with chronic hepatitis C, the epidemiological characteristics of hepatitis C virus (HCV) genotypes in France. Data from 26 referral centres, corresponding to 1769 patients with chronic hepatitis C were collected consecutively during a 6-month period. HCV genotyping in the 5'-non-coding region (NCR) was performed in each center using the line probe assay (LiPA, in 63% of cases), sequencing (25%) or primer-specific polymerase chain reaction (PCR) (12%). HCV genotypes 1a, 1b, 2, 3, 4, 5, non-subtyped 1 and mixed infection were found in 18, 27, 9, 21, 9, 3, 11 and 1% of our population, respectively. HCV genotype distribution was associated with gender, age, source and duration of infection, alanine aminotransferase (ALT) levels, cirrhosis, alcohol consumption, hepatitis B virus (HBV) and human immunodeficiency virus (HIV) coinfection. In multivariate analysis, only the source of infection was the independent factor significantly associated with genotype (P = 0.0001). In conclusion, this study shows a changing pattern of HCV genotypes in France, with i.v. drug abuse as the major risk factor, an increase of genotype 4, and to a lesser extent 1a and 5, and a decrease of genotypes 1b and 2. The modification of the HCV genotype pattern in France in the next 10 years may require new therapeutic strategies, and further survey studies.

Abstract
BACKGROUND A secondary end point of the NBL90 protocol (Rubie H et al. Pediatr Oncol 2001;36:247-250) was the concern in this infant population for possible carboplatin-(CBDCA) induced late side effects including impaired renal and hearing functions. PROCEDURE Glomerular filtration rate (GFR), tubular function (TF), pure tone audiometry (PTA), high-frequency, and transient evoked-otoacoustic emission were prospectively assessed in 30 children alive and disease-free 6 years after the end of the treatment. RESULTS Median age at diagnosis and at assessment was 4.7 months and 7 years, respectively. Blood pressure was < or =97.5 centile in all children. The mean estimated GFR was 114 +/- 13 ml/min/1.73 m(2) by Schwartz formula [range 87-145]. TF assessment failed to demonstrate any impairment. 29/30 children had grade 0 ototoxicity and all transient evoked otoacoustic emission were normal. CONCLUSIONS With a 6-year follow-up the combination of VP16 and carboplatin given at conventional doses is safe on renal and hearing functions in infants with unresectable neuroblastomas treated according to SFOP NB90.

Abstract
Between November 1990 and November 1996, EORTC Children Leukemia Group conducted a randomized trial in de novo acute lymphoblastic leukemia and lymphoblastic non-Hodgkin's lymphoma patients using a Berlin-Frankfurt-Munster protocol to evaluate the monthly addition of intravenous 6-mercaptopurine (i.v. 6-MP) (1 g/m(2)) to conventional continuation therapy comprising per oral MTX weekly and 6-MP daily. Only during the first 18 months of the randomization period, 6-MP p.o. was interrupted for 1 week after each i.v. 6-MP. A total of 877 patients was randomized to either no i.v. 6-MP (Arm A) or additional i.v. 6-MP (Arm B). A total of 217 relapses (91 in Group A vs 128 in Group B) and 13 deaths in CR (5 vs 8) were reported; a total of 134 patients (55 vs 79) died. The median follow-up was 7.6 years. At 8 years, the disease-free survival rate was lower (P=0.005) in Arm B (69.1% (s.e.=2.2%)) than in Arm A (77.9% (s.e.=2.0%)), and the hazard ratio was 1.45 (95% CI 1.12-1.89). In conclusion, as delivered in this study, i.v. 6-MP was detrimental to event-free survival.

Abstract
To determine the results of allogeneic hematopoietic stem cell (HSC) transplantation for chronic myelogenous leukemia (CML) at various stages of the disease in children, a retrospective analysis was carried out on the outcome of transplants performed on 76 children and teenagers with CML between 1982 and 1998. In all, 60 patients were transplanted from a matched sibling donor (MSD) and 16 from a matched unrelated donor (MUD). There was a higher incidence of acute graft-versus-host disease after MUD transplantation (P<10(-3)). The main cause of death was transplant-related toxicity in both groups. In MSD recipients, the probability of relapse at 5 years for patients transplanted in the first chronic phase was lower than in patients transplanted in the advanced phase (relative risk (rr)=5.90; 95% confidence interval (CI), 1.85-18.82, P<0.01). The estimated 5-year event-free survival (EFS) rate was higher after MSD vs MUD transplantation (61% (95% CI, 48-73%) vs 27% (95% CI, 4-49%), rr=0.25, P<10(-3)). In children transplanted from MSD, the 5-year EFS was higher when transplantation was performed in the first chronic phase vs the advanced phases (73% (95% CI, 59-87%) vs 32% (95% CI, 10-54%), P<10(-3)). Disease status at transplantation was the unique factor influencing survival in patients undergoing transplantation from MSD with a better outcome for those transplanted in the first chronic phase. Allogeneic HSC offers a possibility of curing childhood CML with a significant advantage for patients transplanted in chronic phase using a human leukocyte antigen-identical sibling donor.

Abstract
The objective of the present study was to investigate the role of early common infections and perinatal characteristics in the aetiology of childhood common leukaemia. A case–control study was conducted from 1995 to 1998 in France, and included 473 incident cases of acute leukaemia (AL) (408 acute lymphoblastic leukaemia (ALL), 65 acute myeloid leukaemia (AML) age-, sex- and region-matched with 567 population-based controls. Data on the medical history of the child and his/her environment were collected using self-administered questionnaires. Analyses were conducted using nonconditional logistic regression. A slight negative association with early infections was observed (OR=0.8; 95% CI (0.6–1.0)). The association was stronger for early gastrointestinal infections. Early day-care was found to be associated with a decreased risk of AL (OR=0.6; 95% CI (0.4–0.8) and OR=0.8; 95% CI (0.5–1.2) for day-care starting before age 3 months and between 3 and 6 months, respectively). No association with breast-feeding was observed, irrespective of its duration. A birth order of 4 or more was associated with a significantly increased risk of AL (OR=2.0; 95% CI (1.1–3.7) with ALL). A history of asthma was associated with a decreased risk of ALL (OR 0.5; 95% CI (0.3–0.90). Although the results regarding birth order and breast-feeding do not fit with Greaves' hypothesis, the study supports the hypothesis that early common infections may play a protective role in the aetiology of childhood leukaemia, although this effect was not more marked for common ALL.

Abstract
The triple association of leukemia, xanthogranulomas, and type 1 neurofibromatosis was first described in 1958. Most leukemias were juvenile myelomonocytic leukemias (JMML), usually called juvenile chronic myelogenous leukemia. We describe a 22-month-old female child with neurofibromatosis 1, xanthomagranulomas, and a JMML. Her mother and her brother also had cutaneous café-au-lait spots. Our patient was treated with mercaptopurine and improved. However, 9 months later she experienced a blastic transformation. The presence of xanthomagranulomas and NF1 in a young child should alert to a possible development of JMML, especially in patients with a family history of NF1.

Abstract
Biochemical markers of bone turnover have for several years been considered as valuable parameters in research clinical studies, but their use in individual patients is still debated. Recently several position papers have proposed guidelines for their use in clinical practice in patients with post menopausal osteoporosis. In the present article, we report the results of a survey which aims at comparing the actual modalities of prescription of French physicians with the above-mentioned recommendations. We contacted by phone clinical chemists from 158 different hospitals and asked them to transmit to the concerned physicians of their hospital a detailed questionnaire for assessing which bone marker(s) is (are) prescribed and for which purpose (s), and if not prescribed, the reason of non prescription. We were able to analyze 309 questionnaires from 89 hospitals including 5 specialties, rheumatology (35.9%), endocrinology (18.1%), gynecology (11.0%), internal medicine (22.0%) and geriatry (12.9%). The results showed large discrepancies between the mode of prescription of a subset of physicians and the guidelines. The most often evoked reason for non prescription was a lack of information about bone markers suggesting a need for teaching courses. This survey has also shown that many physicians do not know exactly which parameters are effectively measured in their hospital and which are addressed to specialized laboratories underlining the importance of the dialogue between clinicians and clinical chemists. We propose that in a given hospital, the present article may serve as a basis for a discussion between clinicians and biologists about the development and/or the optimization of the measurements of these markers of bone turnover.

Abstract
PURPOSE To evaluate the frequency of metabolic complications and dialysis due to tumor lysis syndrome in patients with B-cell advanced-stage non-Hodgkin's lymphoma (NHL) and L3 leukemia at initiation of chemotherapy including the use of urate-oxidase. PATIENTS AND METHODS Retrospective review of the clinical records of 410 patients with stage III and IV B-cell NHL and L3 leukemia treated in France and prospectively registered in the LMB89 protocol. RESULTS During the first week of chemotherapy, only 34 of 410 patients recorded metabolic problems that included hypocalcemia (< 70 mg/dl) in 24 patients, hyperphosphatemia (> 6.5 mg/dl) in 28 and elevation of creatinine > or = 2 SD in 16. Six patients underwent dialysis for life-threatening problems and a seventh as a preventive measure. In the other 27 cases, metabolic problems were successfully resolved using urate-oxidase in combination with alkaline hyperhydration. Among the 410 patients, one case of hemolysis was reported and there was no severe allergic reaction to urate-oxidase. CONCLUSIONS Only 1.7% of patients in our study receiving urate-oxidase during their induction chemotherapy needed renal dialysis. Urate-oxidase was well tolerated, and used as prophylaxis and/or treatment of hyperuricemia and tumor lysis syndrome consistently gave a lower rate of renal and metabolic complications than in other series of similar patients.

Abstract
We report the results of the cross-cultural adaptation and validation into the French language of two health status instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health related quality of life instrument designed to capture the physical and psychosocial well-being of children independently from the underlying disease. Five hundred children were enrolled including 306 patients with JIA classified into systemic (23%), polyarticular (22%), extended oligoarticular (25%), and persistent oligoarticular (30%) subtypes, and 194 healthy children. Both instruments were reliable with intra-class correlation (ICC) coefficients for the test-retest procedure of 0.91 for the CHAQ, and 0.87 and 0.89 for the physical and psychosocial summary scores of CHQ, respectively. Agreement between parents and children evaluated for the CHAQ was high with an ICC of 0.89 for the disability index; weighted kappa coefficients for the 8 domains ranged from 0.61 to 0.72. Convergent validity was demonstrated by significant correlations with the JIA core set of variables (physician and parent global assessment, scores for active joints and joints with limited range of motion, erythrocyte sedimentation rate) for both instruments. Both CHAQ and CHQ discriminated between healthy and JIA children, but only the disease specific CHAQ questionnaire discriminated clearly between the 4 JIA subtypes. In conclusion, the French versions of the CHAQ and the CHQ are reliable, and valid health assessment questionnaires to be used in children suffering from JIA.

Abstract
PURPOSE The European Organization for Research and Treatment of Cancer 58881 study was designed to test in a prospective multicentric randomized trial the value of high-dose (HD) intravenous (IV) cytarabine (Ara-C) added to HD IV methotrexate (MTX) to reduce the incidence of CNS and systemic relapses in children with increased-risk acute lymphoblastic leukemia (ALL) or stage III and IV lymphoblastic lymphoma treated with a Berlin-Frankfurt-Munster (BFM)-based regimen. PATIENTS AND METHODS After completion of induction-consolidation phase, children with increased-risk (risk factor > 0.8 or T-lineage) ALL or stage III and IV lymphoblastic lymphoma were randomized to receive four courses of HD MTX (5 g/m(2) over 24 hours every 2 weeks) and four intrathecal administrations of MTX (Arm A) or the same treatment schedule with additional HD IV Ara-C (1 g/m(2) in bolus injection 12 and 24 hours after the start of each MTX infusion) (Arm B). RESULTS Between January 1990 and January 1996, 653 patients with ALL (593 patients) or lymphoblastic lymphoma (60 patients) were randomized: 323 were assigned to Arm A (without Ara-C) and 330 to Arm B (with Ara-C). A total of 190 events (177 relapses and 13 deaths without relapse) were reported, and the median follow up was 6.5 years (range, 2 to 10 years). The incidence rates of CNS relapse were similar in both arms whether isolated (5.6% and 3.3%, respectively) or combined (5.3% and 4.6%, respectively). The estimated 6-year disease-free survival (DFS) rate was similar (log-rank P =.67) in the two treatment groups: 70.4% (SE = 2.6%) in Arm A and 71.0% (SE = 2.5%) in Arm B. The 6-year DFS rate was similar for ALL and LL patients: 70.2% (SE = 1.9%) versus 76.3% (SE = 5.6%). CONCLUSION Prevention of CNS relapse was satisfactorily achieved with HD IV MTX and intrathecal injections of MTX in children with increased-risk ALL or stage III and IV lymphoblastic lymphoma treated with our BFM-based treatment protocol in which cranial irradiation was omitted. Disappointingly, with the dose schedule used in this protocol, HD Ara-C added to HD MTX, although well tolerated, failed to further decrease the incidence of CNS relapse or to improve the overall DFS.

Abstract
We report two cases of leptomeningeal metastatic dissemination to the spinal cord of a grade B oligodendroglioma. Diagnosis was suspected on MRI but imaging findings were nonspecific. The pathways by which the intramedullary part of the spinal is reached by metastatic cells remains controversial. In the reported cases, both frontal and cystic primary intracerebral lesions were observed. Chemotherapy after radiotherapy appears to improve outcome. Nevertheless, prognosis remains very poor.

Abstract
We present here the long-term results of three randomized clinical trials conducted on children with newly diagnosed acute lymphoblastic leukemia (ALL) between 1983 and 1998 by the Children Leukemia Cooperative Group (CLCG) from EORTC. In study 58831/32, the overall event-free survival (EFS) rates (+/- s.e.) at 6 and 10 years were 66% +/- 1.8% and 65% +/- 1.8%, respectively, and the risk of isolated central nervous system (CNS) relapse was 6% +/- 1% and 7% +/- 1%, respectively. In patients with a standard risk of relapse the omission of cyclophosphamide had no adverse effect on disease-free survival rates at 10 years (trial 58831). In medium- and high-risk patients the omission of radiotherapy did not increase the risk of CNS or systemic relapse (trial 58832). In study 58881 (1989-1998) the overall EFS rate at 8 years was 68.4% +/- 1.2% and the risk of isolated CNS relapse was 4.2%+/-0.5%. In this trial which adressed three randomized questions, the following results were obtained: the combination of cytarabine at high doses with methotrexate at high doses during interval therapy did not improve prognosis. The addition of 6-mercaptopurine iv during maintenance increased the risk of late relapse. E. coli asparaginase was more toxic and has a higher efficacy than Erwinia asparaginase. Leukocyte counts >100 x 10(9)/l, specific genetic abnormalities, a poor initial response to steroids or a high level of minimal residual disease at early time points were consistently associated with an adverse prognosis in the 58881 trial.

Abstract
Biochemical markers of bone turnover have been developed over the past 20 years that are more specific for bone tissue than conventional ones such as total alkaline phosphatase and urinary hydroxyproline. They have been widely used in clinical research and in clinical trials of new therapies as secondary end points of treatment efficacy. Most of the interest has been devoted to their use in postmenopausal osteoporosis, a condition characterized by subtle modifications of bone metabolism that cannot be detected readily by conventional markers of bone turnover. Although several recent studies have suggested that biochemical markers may be used for the management of the individual patient in routine clinical practice, this has not been clearly defined and is a matter of debate. Because of the crucial importance to clarify this issue, the Société Francaise de Biologie Clinique prompted an expert committee to summarize the available data and to make recommendations. The following paper includes a review on the biochemical and analytical aspects of the markers of bone formation and resorption and on the sources of variability such as sex, age, menstrual cycle, pregnancy and lactation, physical activity, seasonal variation and effects of diseases and treatments. We will also describe the effects of pre-analytical factors on the measurements of the different markers. Finally based on that review, we will make practical recommendations for the use of these markers in order to minimize the variability of the measurements and improve the clinical interpretation of the data.

Abstract
The Amplicor HCV Monitor test for quantitative determination of serum or plasma hepatitis C virus (HCV) RNA was modified recently and introduced onto the Cobas Amplicor instrument to automate fully amplification, detection and calculation of results. This new version (v2.0) was evaluated in a routine diagnostic laboratory. The sensitivity and reproducibility were assessed on well-characterized panels (Eurohep) and clinical samples. HCV RNA levels measured by the v2.0 Monitor test were about 1log(10) higher than those detected by the previous version test, and genotypes 1 and 3 were quantified with equal sensitivity. Within the linear dynamic range of 10(3) to 10(6) copies/ml, the coefficients of variation for both intra- and inter-assay reproducibility ranged from 1.9 to 2.95%. This test system was found to be a reliable and labor saving assay for the quantification of HCV RNA.

Abstract
The thrombocytopenia and absent radii (TAR) syndrome is a rare disease associating bilateral radial agenesis and congenital thrombocytopenia. Here, we investigated in vitro megakaryocyte (MK) differentiation and expression of c-mpl in 6 patients. Using blood or marrow CD34(+) cells, the colony-forming unit (CFU)-MK number was markedly reduced. CD34(+) cells were also cultured in liquid medium in the presence of a combination of 3 cytokines (stem cell factor, interleukin-3, and interleukin-6) or megakaryocyte growth and development factor (PEG-rHuMGDF) with or without SCF. In the presence of PEG-rHuMGDF, the majority of mature megakaryocytes (CD41 high, CD42 high) underwent apoptosis. This phenomenon was also observed in cultures stimulated by three cytokines. However, this last combination of cytokines allowed a more complete terminal MK differentiation. Surprisingly, a homogeneous population of CD34(-)CD41(+)CD42(-) cells accumulated during the cultures. This population was unable to differentiate along the myeloid pathways. This result suggests that a fraction of MK cells is unable to differentiate in the TAR syndrome. We subsequently investigated whether this could be related to an abnormality in c-mpl. No mutation or rearrangement in the c-mpl gene was found by Southern blots or by sequencing of the c-mpl coding region and its promoter in any of the patients. Using Western blot analysis, a decreased level of Mpl was found in patient platelets. A decreased level of c-mpl messenger RNA in TAR platelets was also detected with a lower c-mpl-P to c-mpl-K ratio in comparison to adult platelets. Altogether, these results demonstrate that the thrombocytopenia of the TAR syndrome is associated with a dysmegakaryocytopoiesis characterized by cells blocked at an early stage of differentiation.

Abstract
PURPOSE To tailor postinduction therapy for stage 4 neuroblastoma in children who are older than 1 year at diagnosis according to status after induction. PATIENTS AND METHODS From March 1987 to December 1992, 99 patients who were consecutively admitted were included in the Lyon-Marseille-Curie East of France (LMCE)3 strategy. After induction with the French Society of Pediatric Oncology NB87 regimen and surgery, patients who were in complete remission immediately proceeded to consolidation therapy with vincristine, melphalan, and fractionated total-body irradiation (VMT). All other patients underwent a postinduction strategy before VMT, either an additional megatherapy regimen or further chemotherapy with etoposide/carboplatin. RESULTS The progression-free survival (PFS) is 29% at 7 years from diagnosis, which compares favorably with that of a similar cohort of 72 patients previously reported by our group (LMCE1; PFS of 20% at 5 years and 8% at 14 years, P =.004). In the multivariate analysis, only age younger than 3 years at diagnosis (P =.0085) and achievement of complete or very good partial remission after NB87 and surgery (P =.00024) remained significant. The PFS of the 87 patients who were included in the postinduction strategy was significantly better than that of the comparable 62 patients on the LMCE1 study (32% v 11% at 7 years; P =.005). CONCLUSION The progressive improvements in the LMCE results over the last 10 years suggest that improvements in supportive care measures and increases in each component of this strategy (induction, postinduction, consolidation) may all contribute to increased survival rates.

Abstract
We have analyzed factors influencing the outcome of 102 children with acute leukemia given a cord blood transplantation (CBT) and reported to the Eurocord Registry. Seventy patients with acute lymphoblastic and 32 with acute myeloid leukemia were given either a related (n = 42) or an unrelated (n = 60) CBT. Children given CBT during first or second complete remission were considered as belonging to the good-risk group (n = 66), whereas those who received a transplant in a more advanced stage of disease were assigned to the poor-risk group (n = 36). In the related group (RCBT), 12 of 42 patients received transplantation from an HLA-disparate donor, whereas in the unrelated group (UCBT) 54 of 60 received an HLA mismatched CBT. Kaplan-Meier estimates for neutrophil recovery at day 60 were 84% +/- 7% in RCBT and 79 +/- 6% in UCBT (P =.16). In multivariate analysis, the most important factor influencing neutrophil engraftment in UCBT was a nucleated cell dose infused greater than 3.7 x 10(7)/kg (P =.05, relative risk [RR] of 1.85, 95% confidence interval [CI]: 0.98-3.4). The incidence of grade II through IV acute graft-versus-host disease was 41% +/- 8% in the RCBT group and 37% +/- 6% in the UCBT group (P =.59). Kaplan-Meier estimates of 2-year event-free survival (EFS) after RCBT or UCBT were 39% +/- 8% and 30% +/- 7%, respectively (P =.19). In multivariate analysis, the most important factor influencing EFS was disease status at time of transplantation: good-risk patients had a 2-year EFS of 49% +/- 7% as compared to 8% +/- 5% in patients with more advanced disease (P =.0003, RR: 0.40, 95% CI: 0.24 to 0. 65). This was a consequence of both an increased 1-year transplant related mortality and a higher 2-year relapse rate in the poor-risk group (65% +/- 9% and 77% +/- 14%, respectively), as compared with good risk patients (34% +/- 6% and 31% +/- 9%, respectively). These data confirm that allogeneic CBT from either a related or an unrelated donor is a feasible procedure able to cure a significant proportion of children with acute leukemia, especially if transplanted in a favorable phase of disease.

Abstract
We investigated the use of a new conditioning regimen followed by allogeneic bone marrow transplantation (BMT) for treating children with acute lymphoblastic leukaemia (ALL) after relapse within 6 months of the completion of therapy. One hundred and sixteen children with acute lymphoblastic leukaemia in second or subsequent complete remission (CR) underwent allogeneic bone marrow transplantation from HLA-identical siblings after a preparative regimen comprising total body irradiation (TBI), high-dose cytosine arabinoside and melphalan (TAM regimen). The Kaplan-Meier product-limit estimate (mean +/- SE) of disease-free survival (DFS) at 7 years was 59.5 +/- 9% (95% confidence interval). The estimated chance of relapse was 22.5 +/- 15% with a median follow-up of 88.5 months (range 51-132). 26 patients (22.4%) died with no evidence of recurrent leukaemia, mainly from interstitial pneumonitis, veno-occlusive disease or acute graft-versus-host disease (GVHD). Three factors significantly affected DFS: acute GVHD. site of relapse and, for children in second remission after a marrow relapse, the disease status at the time of transplantation. The DFS were 59.02 +/- 12.6%, 37.5 +/- 19.8% and 774 +/- 15% among patients in CR2 after a marrow relapse, in CR3 or in untreated partial marrow relapse, and in CR2 after an isolated CNS relapse, respectively. The lowest DFS was seen in children with acute GVHD grades 3-4. Two significant factors were associated with relapse: the marrow status at the time of transplantation and chronic GVHD. The relapse rate was lower among children in CR2 or with chronic GVHD. We conclude that transplantation after the TAM regimen is an effective therapy for this population with acceptable toxicity, particularly for children in second remission after a very early marrow relapse, or those with early isolated CNS involvement.

Abstract
Eurocord Transplant has established a registry for studying results of cord blood transplant. We have analyzed 78 patients who have received a related CBT between October 1988 and December 1996. The median follow-up time was 29 months (1-99). The median age was 5 years (0.2-20), median weight 19 kg (5-50). Forty-six patients had a malignant disease: 32 acute leukemia (AL), six chronic myeloid leukemia (CML), four myelodysplastic syndrome, two neuroblastoma and two non-Hodgkin lymphoma. Thirty-two patients were transplanted for non-malignant diseases including 17 bone marrow failure syndromes (BMFS), three sickle cell anemia, five thalassemia and seven inborn errors. The donor was an HLA-identical sibling in 60 cases and an HLA-mismatched donor in 18 cases. As conditioning, 36 patients received irradiation and 40 patients received associated busulfan-containing regimens. GVHD prophylaxis consisted of CsA alone in 36 cases, CsA associated with prednisone in eight cases, CsA, methotrexate (Mtx) with or without prednisone in 28 cases and CsA with monoclonal antibody or ATG in four cases. The median number of nucleated cells (NC) infused/kg was 3.9 x 10(7) (0.7-15). One-year survival was 63 +/- 6%. Age, weight, HLA identity and negative cytomegalovirus (CMV) serology in the recipient were significant favorable prognostic factors. Among these 78 patients, the incidence of grade > or = II GVHD was 9% in HLA-matched CBT and 50% in mismatched CBT (P < 0.001). Neutrophil engraftment was associated with age <6 years (P = 0.02) and weight <20 kg (P = 0.02). It was 73% in patients receiving <3.7 x 10(7) nucleated cells (NC) infused/kg and 85% in patients receiving more (P = 0.06). Favorable factors for platelets engraftment were age <6 years (P = 0.03), weight <20 kg (P = 0.002) and HLA identity (P < 0.0001). Related cord blood transplantation offers a good alternative to BMT. Theses results are in favor of freezing cord blood in families in whom a transplant might be indicated.

Abstract
More than 600 mutations have been identified in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene and are known to cause cystic fibrosis (CF). This large number of mutations makes the search of the molecular defects in CF patients difficult. We have used the techniques of denaturing gradient gel electrophoresis (DGGE) and direct DNA sequencing to detect the mutations in 334 CF chromosomes mostly of French origin. The whole coding sequence of the CFTR gene corresponding to the 27 exons and their exon-intron boundaries was studied. 45 different mutations were identified. This method allowed us to detect the molecular defect in 90.5% of the mutant alleles and to report a novel mutation D979V.

Abstract
Bone marrow transplantation (BMT) from matched sibling donors is the therapy of choice for children with high-risk acute lymphoblastic leukaemia in children. It is however not available to more than two-thirds of patients who lack a matched donor. Here, we review the outcome of 28 patients with high-risk ALL who were transplanted in France with alternative marrow sources such as HLA-phenoidentical unrelated volunteers and HLA-partially incompatible relatives. For these patients, we tested the possibility to prevent T-depleted marrow graft rejection by infusing in vivo two monoclonal antibodies directed against adhesion receptors i.e., LFA-1 and CD2. Two previous multicenter trials in children transplanted with partially incompatible bone marrow for inborn errors of metabolism showed their efficacy in this setting. Twenty eight patients were enrolled in this study and followed for a median of 4.4 years. Bone marrow engraftment occurred in 81% of the evaluable patients. Post-transplantation leukaemic relapse was the most frequent cause of death in this group of patients, and occurred in 39% of patients. The second most frequent complication was infectious disease, while an EBV-induced B-lymphocyte proliferative disorder occurred in four patients. In conclusion, T-cell-depletion combined with infusion of anti-LFA-1 and anti-CD2 antibodies is efficient in preventing graft failure and GVHD in this group of children with high-risk leukaemia undergoing partially incompatible BMT. The overall DFS is not improved in contrast to what has been previously observed in patients with immunodeficiencies transplanted with a similar rejection prophylaxis. Other approaches are therefore needed aiming either at preserving donor T-cell mediated immunity or accelerating immune reconstitution.

Abstract
PURPOSE NB87 was designed to test the efficacy of a short, non cross-resistant, induction protocol for unselected patients over 1 year of age with stage 4 neuroblastoma. A secondary objective was to compare in a randomized study the toxicity of two modalities of cisplatin administration. PATIENTS AND METHODS A total of 183 patients received two cycles of alternating sequences: cyclophosphamide 300 mg/m2/d on days 1 to 5, vincristine 1.5 mg/m2/d on days 1 and 5, and doxorubicin 60 mg/m2/d on day 5 (CADO); and cisplatin 40 mg/m2/d and etoposide 100 mg/m2/d on days 1 to 5 (CVP), followed by surgery of the primary tumor (126 patients). Ninety-one were randomized to receive cisplatin either as bolus (BO; n = 48) or continuous infusion (CI; n = 43). International Neuroblastoma Staging System (INSS) and Response Criteria (INRC) were used with emphasis on skeletal evaluation by meta-iodobenzylguanidine (MIBG). RESULTS Hematotoxicity was predominant, with a higher incidence of neutropenia (P = .01) for CADO and of thrombocytopenia for CVP (P < .001). Severe infections, as well as nonhematologic toxicities, occurred more often after the first sequence. Gastrointestinal complications were predominant during both courses of CVP. The toxic death rate, including surgery, was 3%. Complete remissions (CRs) were less frequent on MIBG (45%) compared with marrow (66%) or other metastases (61%). Combining all metastatic sites resulted in a 39% CR rate. After surgery, the final CR rate was 42%. Nephrotoxicity was minimal in both arms (92% normal clearance for CI v 82% for BO). Hearing loss greater than 40 dB at 6,000 to 8,000 Hz was reported equally in both arms (n = 6 for CI v n = 5 for BO). CONCLUSION Intensified chemotherapy using CADO/CVP increases CR rates despite a shorter induction duration. However, the rate of MIBG normalization remains unsatisfactory and could be raised through the dose-intensive use of agents such as cyclophosphamide.

Abstract
OBJECTIVE Skin involvement in children with acute monocytic leukemia or CD30-positive anaplastic large-cell lymphoma is well-known. In contrast, very little is known about the malignant cutaneous infiltrates in children with acute lymphoblatic leukemia (ALL) or lymphoblastic lymphoma (LBL). This study was designed to determine the frequency of these specific lesions in childhood ALL or LBL and the characteristics of such patients. DESIGN We studied the clinical and biological findings of children with cutaneous involvement at initial diagnosis of ALL or LBL enrolled between August 1989 and March 1995 in the multicentric trial 58881 of the Children's Leukemia Cooperative Group of the European Organization of Research and Treatment of Cancer (EORTC). RESULTS Among the 1359 children enrolled in the multicenter trial EORTC 58881, 24 presented with skin involvement at diagnosis. ALL was diagnosed in 15 patients and LBL in 9. In 15 cases, skin lesions were observed within a median time of 6 weeks (range, a few days to 8 months) before the diagnosis of the hematologic disease. Twenty-one children had at least one skin lesion located on the head. Diffuse cutaneous lesions were observed in 7 infants with high-risk ALL. Seventeen of the 24 children remain in the first complete remission (median follow-up of 3 years; range 2 months to 5 years) and 3 are in the second remission with a follow-up of 14 to 24 months. CONCLUSION The present study demonstrates that cutaneous involvement can be an early manifestation of ALL or LBL. Cutaneous leukemic infiltrates can be observed in children with standard risk as well as in high-risk ALL. Cutaneous involvement in children with LBL is mainly associated with a B-cell precursor immunophenotype of the lymphomatous cells. The most frequent location of skin lesions in children with ALL or LBL is on the head. Further studies are needed to evaluate the prognosis of children with such involvement at diagnosis.

Abstract
PURPOSE The in vivo response to prephase corticosteroid therapy for 1 week has been described as a major prognostic factor in childhood acute lymphoblastic leukemia (ALL). Patients with less than 1,000 blasts/microL at day 8 are considered responders and have a better prognosis. This prephase therapy is usually considered as an evaluation of glucocorticoid sensitivity. In fact, it also includes one intrathecal (IT) injection of methotrexate (MTX). In this study, we try to clarify the influence of this injection of IT MTX on the response to the prephase therapy. PATIENTS AND METHODS This retrospective study analyzed the response to prephase therapy in 1,044 children with ALL entered onto the European Organization for Research and Treatment of Cancer (EORTC) trial 58881 of the Children's Leukemia Cooperative Group (CLCG). Analysis was restricted to 732 cases with an initial blast count greater than 1,000/microL. The following variables were tested to analyze response to prephase therapy: age, sex, evaluated risk factor (RF), blast count on day 0, actual dose of prednisolone administered, immunophenotype (T v non-T), and day of IT MTX. For statistical analysis, the variable day of IT MTX (D) was stratified into three groups: group 1 if D less than 2, group 2 if D > or = 2 but < or = 6, and group 3 if D greater than 6. RESULTS All variables tested had a significant influence on response to the prephase therapy. This was especially true for IT MTX: 90.4% responders in group 1, 76.9% in group 2, and 70% in group 3 (P < .001). Immunophenotype was also a major predictor of response to the prephase: 88% responders in B-lineage ALL versus 56.2% in T-lineage ALL. IT MTX had a significant influence in B-lineage ALL (96% responders in group 1, 90% in group 2, and 79% in group 3; P < .001), whereas the influence could not be detected in T-lineage ALL. CONCLUSION These results clearly demonstrate a therapeutic systemic effect of low doses of IT MTX in childhood ALL, and response to prephase therapy should not be considered as an in vivo test for cortico-sensitivity only. Earlier use of IT MTX leads to a higher percentage of responders.

Abstract
Uniparental isodisomy is defined as the inheritance of two copies of the same parental chromosome and can result in defects when it produces homozygosity for a recessive mutation or in the presence of imprinting. We describe the detection of a chromosome 6 uniparental isodisomy in a 9 year old girl, discovered during a search for an HLA identical sib. HLA typing, erythrocyte phenotyping, and genotypes of microsatellite polymorphisms were compatible with a paternal isodisomy of chromosome 6, with normal biparental origin of the other chromosomes. Paternal cells were not responsive to the patient's cells in mixed lymphocyte cultures. This fortuitous detection of a chromosome 6 isodisomy suggests that cases of chromosome 6 UPD may not be deleterious and may therefore go undetected.
