Abstract
PURPOSE To determine the value of gray-scale ultrasonography (US) and Doppler US in the prediction, diagnosis, and prognostic assessment of hepatic veno-occlusive disease (HVOD). MATERIALS AND METHODS One hundred patients (median age, 22 years; range, 18 months to 59 years) receiving total body irradiation or busulfan therapy as intensive treatment before hematopoietic stem cell transplantation were studied prospectively. Each patient underwent gray-scale and Doppler US examination before transplantation and weekly thereafter while hospitalized (about four examinations per patient). Seven gray-scale morphologic criteria and seven Doppler criteria were studied, yielding three individual scores: gray-scale score, Doppler score, and total score. RESULTS Twenty-five patients developed HVOD; nine of these patients died. Positive predictive values of the 14 criteria were 31%-95%, and negative predictive values were 85%-96%. The three scores correlated with the clinical diagnosis of HVOD. Depending on the cutoff value, the positive predictive value of the total score was 44%-89% and the negative predictive value was 91%-98%. The gray-scale and Doppler criteria differed significantly between patients with HVOD and those with graft-versus-host disease of the liver (P = 10(-4)). CONCLUSION Even if there is overlap in findings between patients with and those without HVOD, gray-scale and Doppler US are valid for positive and differential diagnosis and have predictive and prognostic relevance.

Abstract
A prospective economic analysis of autologous peripheral blood progenitor-cell transplantation (PBPCT) versus autologous bone marrow transplantation (BMT) was performed as part of a randomised clinical trial in 129 patient (adults and children) receiving high-dosage antineoplastic therapy for non-leukaemic malignant disease. The clinical assessment criteria of the study were the duration of thrombocytopenia (< 30 x 10(9)/L and < 50 x 10(9)/L) and of granulocytopenia (< 0.5 x 10(9)/L). The cost of medical resources used was the primary economic end-point. We also calculated the cost of reaching 2 specified haematological end-points: platelet recovery (> or = 30 x 10(9)/L) and granulocyte recovery (> or = 0.5 x 10(9)/L). Economic analysis was based on the French hospital perspective. Haematological recovery was significantly quicker in the PBPCT groups (adults and children) compared with the BMT groups. Economic study revealed that the PBPCT groups were clearly less expensive with regard to costs up to discharge (17% decrease of the average cost for adults and 29% for children) and those associated with specified haematological end-points. The global costs of PBPCT were lower than those of BMT for these adult and paediatric populations. Economic arguments can clearly be added to clinical ones in favour of substitution of autologous PBPCT for autologous BMT. International comparisons of diffusion of PBPCT could be of great interest for further economic research into medical innovation.

Abstract
BACKGROUND Previous studies have suggested that peripheral blood stem cell (PBSC) transplantation has an advantage over autologous bone marrow transplantation. OBJECTIVE To compare the hematologic recovery and costs associated with PBSC transplantation with those associated with autologous bone marrow transplantation in patients receiving high-dose chemotherapy for solid tumors or lymphomas. DESIGN Multicenter, randomized, controlled clinical trial. SETTING French Federation of Cancer Centers, located in cancer facilities or public hospitals with transplantation units. PATIENTS Children and adults with solid tumors or lymphomas who were candidates for high-dose chemotherapy. INTERVENTIONS Bone marrow or filgrastim-mobilized PBSCs. MEASUREMENT The major and point was the duration of thrombocytopenia (platelet count < 50 x 10(9)/L). An economic evaluation of both types of transplantation was done prospectively to measure costs and cost-effectiveness. RESULTS 129 patients entered the trial; 64 had PBSC transplantation, and 65 had bone marrow transplantation. The median duration of thrombocytopenia was 16 days in the PBSC group and 35 days in the bone marrow group (P < 0.001). All of the other clinical end points studied (time to last platelet transfusion, duration of granulocytopenia, number of transfusion episodes, and duration of hospitalization) favored PBSC transplantation. A cost analysis showed that total cost was decreased by 17% in adults and 29% in children with PBSC transplantation; thus, PBSC transplantation was clearly more cost-effective than bone marrow transplantation for both platelet and granulocyte recovery. CONCLUSION Transplantation of PBSCs is associated with more rapid hematologic recovery than is bone marrow transplantation after high-dose chemotherapy for solid tumors or lymphomas. Furthermore, global costs are lower and cost-effectiveness ratios are better with PBSC transplantation.

Abstract
PURPOSE To assess the relevance of N-Myc gene amplification (NMA) as a prognostic factor in localized neuroblastoma (NB) and to evaluate whether less intensive adjuvant treatment is advisable in infants without NMA. PATIENTS AND METHODS Assessment of NBs included clinical and imaging data to allow tumor-node-metastasis (TNM) staging, biologic determinations (N-Myc gene analysis), and standard histology and work-up to eliminate metastatic spread (metaiodobenzylguanidine [MIBG] scintigraphy and extensive bone marrow staging). Resectability was defined according to imaging findings. Chemotherapy was indicated in children older than 1 year at diagnosis who had postoperative residual disease or lymph node (LN) involvement, in infants with NMA, or as primary treatment in children with an unresectable NB, including dumbbell tumors. Radiotherapy was recommended in children older than 1 who presented with persistent gross residual disease at the end of therapy. RESULTS Between 1990 and 1994, 316 consecutive children who presented with a localized NB were registered in the NBL 90 study. The median age was 12 months, and 42 patients had dumbbell tumors (13%). NMA was found in 22 of 225 assessable children (10%) and correlated with adverse prognostic indicators such as age older than 1 year, an abdominal primary tumor, a large tumor (T3), and unresectability. Among 186 children who had primary excision, five died of surgery-related complications. Primary chemotherapy was given to 130 patients, which allowed removal of the tumor in all but four. The 5-year overall survival (OS) and event-free survival (EFS) rates were, respectively, 91% and 84% with a median follow-up time of 36 months. The outcome of infants and older children was similar (P = .2). EFS of patients with resectable tumors was slightly better than with unresectable primary tumors (EFS, 89% v 78%; P = .02). In dumbbell NBs, neurologic recovery was achieved in 74% of cases that presented with symptoms, and initial laminectomy was avoided in 75% of children. In a univariate analysis, large tumors, high neuron-specific enolase (NSE) and lactate dehydrogenase (LDH) levels, positive LNs, macroscopic residue, and NMA adversely influenced outcome. In the multivariate analysis, NMA was the most powerful unfavorable predictive indicator: OS and EFS rates for these children were 36% and 32%, compared with 98% and 90% in nonamplified tumors (P < .001). CONCLUSION Our data confirm the overall good prognosis of localized NBs, even when unresectable. NMA is the most relevant adverse prognostic factor in localized NBs, and more intensive treatment should be investigated in these patients. Prospective studies of other biologic factors are warranted to tailor therapy more accurately. The EFS of children who underwent primary surgery was excellent, and further justifies elimination of adjuvant treatment provided they have no NMA. Despite the elimination of postoperative therapy, infants with non-NMA tumors have an excellent outcome, which suggests that initial chemotherapy can be further reduced in case of unresectable NBs.

Abstract
Craniospinal irradiation is the gold standard treatment used in non metastatic medulloblastoma as prophylaxis against central nervous system (CNS) metastases. However, given the severe late effects caused by this procedure in children under 3 years of age, most pediatric oncologists are currently treating these patients with conventional chemotherapy in order to postpone or even avoid irradiation. In the French Society of Pediatric Oncology (SFOP) this attitude has been adopted since 1990. Among the patients treated without radiotherapy, 20 relapsed while on conventional chemotherapy and were entered in a study of high-dose chemotherapy (HDC) followed by autologous bone marrow transplantation (ABMT). Their median age at diagnosis was 23 months (range: 5-71 months) and the relapse occurred at a median time of 6.3 months after the initiation of chemotherapy. Complete surgical removal of the local relapse was the first treatment in 4/20 patients who were not evaluable for response. Sixteen of the 20 patients had measurable disease at the primary site (9 patients), or at metastatic sites (3 patients) or both (4 patients). The conditioning regimen consisted of combination busulfan 600 mg/m2 over 4 days and thiotepa 900 mg/m2 over 3 days. After recovery from aplasia, patients with a local relapse received local radiotherapy limited to posterior fossa. Among the 16 patients with measurable disease, 6 complete responses, 6 partial responses, 3 non response, were observed following HDC (response rate 75%). One patient was not evaluable. For the 20 patients, the event free survival (EFS) is 50%. Among the surviving patients, the median follow-up is 39.5 months post BMT (range: 21-92 months). Ten patients who developed a local relapse or local progression are alive with non evidence of disease (NED) without craniospinal irradiation. Among the 7 patients who developed a metastases or progression of metastases, only 1 is alive. Toxicity was high but manageable. One complication-related death occurred 1 month post BMT. With a 75% response rate, this HDC proved to be very efficient in relapsed medulloblastoma. A longer follow-up is necessary to demonstrate whether, after a local relapse, HDC could replace craniospinal irradiation as prophylaxis against CNS metastases.

Abstract
Neuroblastoma shows remarkable heterogeneity, ranging from spontaneous regression to progression toward highly malignant tumors. In search of genetic abnormalities that could explain this variability, we have characterized neuroblastoma tumors by using multiple fluorescent hybridizations. Our results indicate that chromosome 17 is rearranged very frequently in the form of unbalanced translocations with numerous chromosomal partners, all leading to the presence of supernumerary copies of a 25 Mb chromosomal region originating from 17q23.1-qter. Additional 17q material was detected in more than 90% of untreated high-grade neuroblastomas and, along with 1p36 deletion, should represent the most frequent genetic abnormality of neuroblastoma observed until now.

Abstract
PURPOSE The use of in vitro purging of bone marrow in autologous bone marrow transplantation (ABMT) for non-Hodgkin's lymphoma (NHL) has been a controversial issue; its benefit is as yet unproven. Its effect on the clinical outcome of ABMT in these patients is still unclear. We look at this issue using data from the European Blood and Marrow Transplant (EBMT) Lymphoma Registry. PATIENTS AND METHODS Seventeen hundred twenty-six patients with NHL have been reported to the EBMT registry, of whom 270 had bone marrow purged at transplant. Two hundred twenty-four of these patients were compared with a case-matched group of 224 unpurged patients who had undergone the same procedure. The case matching was made following selection of the main prognostic factors for progression-free survival (PFS) by multivariate analysis. Response, complications, and outcome in ABMT were analyzed. RESULTS Time to hematologic engraftment, response to ABMT, and number of procedure-related deaths were similar in purged and unpurged patients. The overall survival (OS) rate was 54% at 5 years in purged patients and 48.3% in unpurged patients (P = .1813). The PFS rate was 44.3% and 44.6%, respectively (P = .1961). Patterns of relapse, including bone marrow relapse, were similar in both groups. Patients with low-grade lymphoma did not have a significantly improved PFS if the bone marrow was purged (P = .1757); however, they did have a significantly improved OS (P = .00184). This increased OS was found to be associated with non-totalbody irradiation (TBI) conditioning and also with the purged patients undergoing transplantation at large transplant centers (P = .0016). CONCLUSION Purging of bone marrow in ABMT for NHL does not affect the rate of hematologic engraftment or risk of procedure-related death (PRD). There is no significant difference in PFS for patients whose bone marrow is purged as compared with unpurged.

Abstract
BACKGROUND Vertigo is a common symptom that often remains unexplained despite extensive medical evaluation. Psychiatric and psychosomatic disorders are usually considered after all somatic causes of vertigo have been ruled out. METHODS Eighty-three patients referred to neurological or psychosomatic outpatient treatment received an extensive neurootologic and psychosomatic evaluation: one (or two) diagnostic psychiatric psychodynamic exploration(s), a structured interview, psychometric tests (SCL-90-R, STAI-G X2 and GBB). The patients were divided into four diagnostic groups: psychic causes only (psychogenic group), neurootologic causes only (somatic group), both diagnoses (psychosomatic group), neither diagnosis (group IV). RESULTS Twenty-three patients had organic vertigo, thirty-nine patients had psychogenic vertigo and in seventeen cases a vestibular lesion initiated the development of a neurotic disorder, particular anxiety disorder. Most of the patients of the psychogenic and psychosomatic group had anxiety or phobic disorders. The patients with psychogenic or psychosomatic symptoms of vertigo generally report a higher level of subjective distress; the periods of disability are significant longer. CONCLUSIONS The study suggests that assessment of psychiatric and psychosomatic symptoms should always accompany, not follow, neurootologic evaluation of vertigo. An early interdisciplinary therapy should be started to prevent the chronicity of the symptomatology.

Abstract
Humoral immunodeficiency after ABMT may worsen the course of infectious complications as already described in this clinical setting; children with low Ig values of the three isotypes during the first week after ABMT experienced more severe infections during the procedure than those with normal values. The aim of the study was to establish the prevalence, the duration and the risk factors of Ig deficiency after ABMT. Serum Ig levels of 160 children treated with high-dose chemotherapy (HDCT) followed by ABMT for solid tumors were studied prospectively before HDCT and weekly from the day after transplantation until the patients were discharged from the unit, as were the associations of the following covariates: patient characteristics, previous conventional chemotherapy (CCT), conditioning regimens, marrow graft and complications following ABMT. Serum Ig deficiency for at least one isotype was already present before HDCT in half of the children and mean serum Ig values decreased after HDCT. Serum Ig deficiency was early (day 7), inconstant, heterogeneous (IgM deficiency was more frequent and lasted longer) and brief (< 1 month). Children with low Ig values before HDCT were at high risk of profound and prolonged humoral immune deficiency. Previous CCT with more than six different drugs was the main risk factor for low serum IgM values before HDCT, on day 7 and on day 21 post-HDCT. This study shows that Ig replacement therapy could be useful after ABMT provided it is given to the patients defined on the basis of these specific risk factors and serum Ig levels before HDCT.

Abstract
BACKGROUND Neuroblastoma is the most common malignant cause of spinal compression in the pediatric population. More than 30% of patients who are impaired prior to treatment remain impaired after the completion of therapy. Those who do not improve after decompressive laminectomy may go on to develop severe delayed spinal deformities. METHODS To decrease the long term sequelae of routine neurosurgical intervention for all intraspinal extensions of neuroblastoma, the French NBL 90 Study was formulated to use chemotherapy as a first-line treatment for all nonmetastatic neuroblastomas with intraspinal extension. Neurosurgical decompression and excision was recommended only for patients demonstrating rapid neurologic deterioration. RESULTS The overall survival of the 42 patients registered was 97%. Initial neurologic impairment was present in 27 patients (64%), including 11 with paraplegia. Thirty-two patients received chemotherapy as first-line treatment. Complete regression of the intraspinal component was observed in 13 patients and partial regression of greater than 50% of the initial volume in 5 patients. Of 19 evaluable patients presenting with a neurologic deficit and treated with primary chemotherapy, recovery was completed in 11 and partial in 3. Four patients failed to recover from long-standing pretreatment paraplegia. Only one patient worsened during therapy, and recovered completely after emergent neurosurgical intervention. Seven patients underwent initial neurosurgical procedures; six had a neurologic deficit and five recovered completely, including all three who presented with acute onset of paraplegia. Three patients had extraspinal surgery as exclusive treatment. Six patients (15%) suffered severe neurologic sequelae. Only one of the patients who underwent surgery required spinal stabilization for progressive deformity, but follow-up is limited. CONCLUSIONS By treating patients with dumbbell neuroblastoma initially with chemotherapy, the authors were able to reduce the size of the intraspinal mass in 58% of patients, improve partial neurologic deficits in 92%, and avoid neurosurgical decompression in 60%. Neurologic deficits also improved in 83% of patients requiring emergent neurosurgical intervention.

Abstract
Sixteen children with refractory or relapsed ependymoma were entered in a phase-II study of high-dose chemotherapy followed by autologous bone marrow transplantation (ABMT). The conditioning regimen consisted of busulfan 150 mg/m2/day for 4 days and thiotepa 300 mg/m2/day for the 3 following days. All patients had previously been treated by surgery and conventional chemotherapy. Eight of them had also received irradiation at doses ranging from 45 to 55 Gy at the tumor site. At the time of transplantation, 9 patients were in first relapse, 5 in second relapse and 2 in third relapse or more; all had measurable disease; 15 patients were evaluable for response. No radiologic response > 50% was observed. Stable disease and progressive disease were documented in 10 and 5 cases, respectively. The duration of response to this treatment, which lasted for a median time of 7 months (range: 5-8 months), was only evaluable in 5 patients who did not receive further treatment after ABMT. To date, there are 3 disease-free survivors at 15, 25 and 27 months all of whom were treated with second complete surgical resection and local radiotherapy (55 Gy). Toxicity was severe, mainly digestive and cutaneous, and 1 toxicity-related death occurred. Unlike medulloblastomas, ependymomas do not appear to be sensitive to this combination therapy. New therapeutic approaches are warranted.

Abstract
The purpose of the study was to determine the maximum tolerated dose of continuous infusion of high-dose VP-16 in combination with high-dose melphalan (HDM) for conditioning before autologous bone marrow transplantation (ABMT). Thirteen children (median age 27 months) with stage IV neuroblastoma were treated with high-dose VP-16 and HDM followed by ABMT as consolidation treatment. All had previously received conventional chemotherapy with a mean number of six drugs. Surgery of the primary tumor had been performed in 12/13. We performed a dose-escalating study of VP-16 from 1800 mg/m2/72 h with 300 mg/m2/72 h dose increments according to toxicity. VP-16 was administered as a 72-h i.v. infusion. Melphalan (140 mg/m2/day) was administered once as an i.v. push. VP-16 pharmacokinetics were analyzed in 12 patients. Five children received 1800 mg/m2/72 h of VP-16, five received 2100 mg/m2/72 h and three, 2400 mg/m2/72 h. The mean duration of granulocytopenia (< 0.5 x 10(9)/1) was 24 days and thrombocytopenia (< 50 x 10(9)/1) was 36 days. No major infectious complications occurred. Gastrointestinal (GI) toxicity was the dose-limiting toxicity. Five severe manifestations of GI toxicity in three patients led us to consider 2400 mg/m2/72 h as the MTD. The mean VP-16 clearance rate was 17.3 ml/min/m2 with continuous infusion. A mean steady-state plasma concentration of 24.2 micrograms/ml (s.d. = 2) and 28.3 micrograms/ml (s.d. = 1.9) was achieved at the 1800 mg/ml and 2100 mg/m2 dose levels, respectively, GI toxicity is dose limiting when VP-16 at 2400 mg/m2/72 h, is associated with HDM. When given as a continuous i.v. infusion, at 2100 mg/m2/72 h, VP-16 associated with HDM is well tolerated before ABMT in young heavily pre-treated children.

Abstract
BACKGROUND Metaiodobenzylguanidine (mIBG) is a guanethidine analog that has demonstrated a high sensitivity and specificity in detecting bone metastases in about 90% of metastatic neuroblastomas. However, the predictive value of initial mIBG scan in neuroblastoma patients older than 1 year of age regarding response to initial chemotherapy has yet to be ascertained. Therefore, a scoring system for grading the positivity of mIBG scans was devised and applied in a retrospective study in an attempt to determine whether this score had a prognostic value in neuroblastoma patients older than 1 year of age at diagnosis. METHODS Eighty-six children, older than 1 year of age, with metastatic neuroblastomas were homogeneously treated and had a mIBG scan performed at diagnosis and following the induction regimen to assess bone metastases. Each mIBG scan was assigned a reproducible score and the predictive value of the initial mIBG score was assessed in order to evaluate response to induction regimen. RESULTS The relative risk of failing to achieve complete remission after four courses of induction therapy was 6.9 times higher in patients who had more than four mIBG spots at diagnosis. A multivariate analysis including the established prognostic factors revealed that the initial mIBG score was the only significant factor (P < 0.001). CONCLUSIONS The initial mIBG scan is of prognostic significance to predict response to chemotherapy for metastatic neuroblastoma in children older than 1 year of age. A prospective study comparing this initial mIBG score with other recently established prognostic factors is warranted.

Abstract
Spontaneous regression of widespread lesions is a characteristic feature of neuroblastoma. One may postulate that the immune response contributes to these clinical regressions. Accordingly, we studied the T-cell receptor (TCR) repertoire of tumor-infiltrating lymphocytes in eight neuroblastoma tumors. The expression of 29 V alpha and 24 V beta gene segment subfamily specificities was analyzed by PCR and compared by computerized densitometry of Southern blots to values obtained in the blood. Overall, the TCR repertoire of these eight patients was diverse, with virtually all V alpha and V beta specificities expressed. Nonetheless, four of these patients showed V beta 2 gene segment subfamily overexpression in the tumor corresponding to local expansion of polyclonal T-cell subpopulations. In one patient, this expansion could be due to local secretion of superantigenic activity, as suggested by the specific stimulation of murine T cells expressing a human V beta 2 chain by supernatant of the corresponding neuroblastoma cell line. In addition, high-resolution analysis of the TCR beta transcript complementarity-determining region 3 sizes identified three patients (of six studied) with marked clonal T-cell expansion in the tumor not seen in the blood. The specific expression of several dominant clono-types in the tumor may be related to the recognition of neuroblastoma-specific antigens in these patients. Together, these results on the TCR repertoire expressed in vivo may lead to the characterization of putative immune response mechanisms (i.e., antigen- or superantigen-driven stimulation) which participate in tumor regression.

Abstract
UNLABELLED Cranio-spinal irradiation is the gold standard treatment used in non metastatic medulloblastoma as prophylaxis against central nervous system (CNS) metastases. However, given the severe late effects caused by this procedure in children under 3 years of age, most pediatric oncologists are currently treating these patients with conventional chemotherapy in order to postpone or even avoid irradiation. In the French Society of Pediatric Oncology (SFOP) this attitude has been adopted since 1987. Among the patients treated without radiotherapy, 20 relapsed while on conventional chemotherapy and were entered in a study of high-dose chemotherapy (HDC) followed by ABMT. Their median age at diagnosis was 23 months (R5-71) and the relapse occurred at a median time of 6.3 months after the initiation of chemotherapy. Complete surgical removal of the local relapse was the first treatment in 4/20 patients who were not evaluable for response. Sixteen of the twenty patients had measurable disease at the primary site (9 patients), or at metastatic sites (3 patients) or both (4 patients). The conditioning regimen consisted of combination Busulfan 600 mg/m2 over 4 days and Thiotepa 900 mg/m2 over three days. After recovery from aplasia, patients with a local relapse received local radiotherapy limited to posterior fossa. RESULTS among the 16 patients with measurable disease, 6 CR, 6 PR, 3 NR, were observed following HDC (response rate 75%). One patient was not evaluable. For the 20 patients, the EFS is 50%. Among the surviving patients, the median follow up is 31 months post BMT (R12-82). Ten patients who developed a local relapse or local progression are alive with NED without craniospinal irradiation. Among the 7 patients who developed metastases or progression of metastases, only one is alive. Toxicity was high but manageable: the median duration of granulocytopenia < 0.5 x 109/l and thrombocytopenia < 50 x 10(9)/l was 13 and 41 days respectively. Bacteremia was documented in 4 cases. Grade > 2 mucositis and diarrhea were observed in 60% of patients. One complication-related death occurred 1 month post BMT. CONCLUSION With a 75% response rate, this HDC proved to be very efficient in relapsed medulloblastoma. A longer follow up is necessary to demonstrate whether, after a local relapse, HDC could replace craniospinal irradiation as prophylaxis against CNS metastases.

Abstract
In order to clarify some of the particularities and pitfalls of the MIBG thoracic scan, we report our experience with 5 children with Stage III or IV neuroblastoma who presented equivocal scans. The physiological thoracic distribution of MIBG in children differs from that in adults and has to be taken in account in the accurate interpretation of the scans.

Abstract
We investigated the long-term pulmonary sequelae of 38 children surviving 3 to 11.5 years (median 7 years) after high-dose chemotherapy (HDC) and autologous bone marrow transplantation (ABMT) without TBI. This cross-sectional study included patients with neuroblastoma (21), non-Hodgkin's lymphoma (7), Ewing's sarcoma (5), rhabdomyosarcoma (3), medulloblastoma (1) and ALL (1). They were asked and examined for clinical signs and underwent a physical examination with chest X-ray; 33/38 had pulmonary function tests (PFT) performed. No obstructive disease was found. Fifteen out of 32 evaluable PFT (47%) were abnormal with a pulmonary restrictive syndrome in 10, and borderline values in five patients. Four of these 15 patients were symptomatic with exertional dyspnea and two of four had abnormal chest X-rays. The etiology was mainly multifactorial, associating HDC with thoracic radiotherapy +/- scoliosis/kyphosis +/- previous thoracotomy +/- post-ABMT interstitial pneumonitis. Only 3/10 patients with a restrictive syndrome had HDC containing BCNU or busulfan as the only risk factor for lung disease. We conclude that the prevalence of late pulmonary sequelae after ABMT without TBI is moderate and rarely due to HDC alone, since most abnormal PFT can be explained by heavy pretreatment prior to ABMT. As symptoms are scarce even in advanced disease, repeated testing and very long-term follow-up are needed.

Abstract
For more than a decade radioiodinated metaiodobenzylguanidine (mIBG) has been commonly used for neuroblastoma imaging. The accuracy of this scintigraphic method in detecting both primary and secondary tumour sites is crucial when evaluating the extent of disease. The aim of our study was to assess the impact of high-activity mIBG scintigraphy on neuroblastoma staging. Eighteen scans (TS) were obtained in 15 children after a therapeutic dose of iodine-131 mIBG and compared to diagnostic mIBG scans (DS) (in eight cases with 131I-mIBG and in ten cases with 123I-mIBG). The superiority of TS over DS was confirmed by the overall results: a total of 220 lesions were disclosed with TS and 171 with DS. However, in only one case did the TS findings, namely skeletal involvement not evidenced on corresponding DS, have an impact on clinical staging. In contrast, neither TS nor DS detected proven bone involvement in four patients. The dose-related sensitivity of mIBG scintigraphy in detecting neuroblastoma tumour sites was confirmed. The ultimate impact of high-dose scans on neuroblastoma management, however, seems limited.

Abstract
Despite intensification of treatment with high-dose chemotherapy (HDC) and autologous bone marrow transplantation (AMBT), the prognosis of poorly responding metastatic neuroblastoma remains bad. Recombinant IL-2 (rIL-2) was used after ABMT to enhance the immune response against the tumor and thereby to improve survival of these patients. In this study, five courses of rIL-2 were administered as a continuous intravenous infusion every 2 weeks, the first course lasting 5 days, and the other four 2 days. rIL-2 treatment was to begin within 120 days of BMT. This study demonstrates the feasibility of rIL-2 soon after HDC and ABMT. The maximum tolerated dose (MTD) was 12 x 10(6) U/m2/day. Clinical toxicity was similar to that observed in adults, moderately increased by the proximity of ABMT; in a previous study we demonstrated that the MTD in non-grafted children was 18 x 10(6) U/M2/day. Nevertheless, half of the patients were not able to receive rIL-2 therapy after ABMT, and only 6/12 received 100% of the planned dose, mainly because of thrombocytopenia. If peripheral stem cell transplantation is demonstrated to enhance platelet recovery, more patients could be treated with rIL-2 with the present schedule. Earlier administration of low-dose rIL-2 after BMT associated with ex vivo rIL-2 treatment of the graft could be a more valid way of using rIL-2 to improve survival.

Abstract
PURPOSE Bone marrow (BM) status is a critical matter when intensified chemotherapy with bone marrow rescue is proposed to improve the survival of patients with poor prognosis Ewing's sarcoma (ES): metastatic or relapsing disease. A systematic bone marrow investigation was performed in all the patients with newly diagnosed ES or relapsing ES to assess their BM status. PATIENTS AND METHODS From January 1985 to February 1989, 59 untreated patients and five patients at the time of relapse had a bone marrow investigation under general anesthesia: two BM biopsies and two BM aspirates until May 1986, then two BM biopsies and 10 BM aspirates. The classical method of smearing each BM aspirate was compared to cytocentrifugation of the pool of BM samples after gradient density separation. RESULTS The BM was involved in 13 of 59 untreated patients. BM was the single site of metastatic spread in only one patient but was involved in 52% of the patients with metastatic disease at other sites. This involvement was focal in several patients and frequent discrepancies were noted between the aspirates and biopsies at the various sites explored. The number of positive cases of BM involvement discovered by the two methods is somewhat limited. However preliminary results indicate a superior rate of positive smears with the pool technique which did however fail to detect involvement in some cases. CONCLUSIONS The present study indicates that 1) BM involvement is a frequent event in metastatic ES (52%); 2) is often multifocal and therefore requires extensive BM investigation; and 3) further investigation of the pool technique to facilitate the BM screening is warranted.

Abstract
The assessment of bone marrow involvement by tumor cells remains an essential problem at diagnosis in pediatric solid tumors. Besides the conventional cytological and histological methods, some modern cell density separation techniques have been described in order to improve the detection of minimal or scattered bone marrow involvement. Immunological or genetical (molecular biology) tools can be used for the recognition of separated cells. In terms of investigations, MRI and MIBG radionucleide scan, although giving no definite proof, have the ability to macroscopically study the scattering of bone marrow invasion in the particular case of neuroblastoma. In some pediatric tumors, especially neuroblastomas and non Hodgkin lymphomas, an extensive bone marrow investigation is mandatory at diagnosis. Such an investigation is only necessary in case of particular criteria at diagnosis of Hodgkin's disease, Ewing' sarcomas, rhabdomyosarcomas and retinoblastomas. All other pediatric solid tumors do not need to be investigated in terms of bone marrow involvement at diagnosis, with the exceptions of advanced disseminated disease or if an autologous bone marrow transplantation is planned.

Abstract
BACKGROUND Some genetic alterations have been shown to have prognostic implication for patients with neuroblastoma: MYCN oncogene amplification, deletion of the short arm of chromosome 1 and di- or tetraploidy. The goal of this study was to analyze these factors in children with neuroblastoma. METHODS Twenty neuroblastoma samples were analyzed with morphologic cytogenetics, and each of them was compared with MYCN amplification status by Southern blot and fluorescent in situ hybridization (FISH) with a genomic probe. RESULTS A complete karyotype was obtained for 14 children. A diploid or tetraploid mode and a 1p deletion were found in most children with advanced stages. MYCN amplification status was totally concordant with both methods in all patients, even in a case with low level amplification. A wide intercellular variation in the amplification level in each MYCN amplified sample was shown. CONCLUSION The use of FISH to assess MYCN amplification rapidly in neuroblastoma is recommended. This method could be very useful in future therapeutic protocols in which treatment is based on MYCN status (and especially for infants and children with localized tumor).

Abstract
The aim was to determine the fluoride retention in plaque-covered and clean incipient enamel lesions after topical application of a CaF2/NaF varnish (Bifluorid 12). In 50 specimens of bovine enamel an incipient lesion was produced with acidic hydroxyethylcellulose (pH 4.8; 72 h). 40 specimens were fluoride varnished; the 10 remaining specimens were used for measuring baseline fluoride content. Each six of the fluoridated specimens were recessed in the buccal aspects of an intraoral appliance worn for 5 days. During the experimental period one side of the appliance was kept clean, and plaque growth was allowed on the other. KOH-soluble and structurally bound fluoride were determined immediately, 1 day, 3 days and 5 days after fluoridation, and compared with the baseline fluoride content of the enamel. Immediately after fluoridation, a considerable amount of KOH-soluble fluoride was bound, but after 5 days 80% had been lost. Simultaneously a significant increase of non-KOH-soluble or structurally bound fluoride was detected in both plaque-covered and clean enamel. It is evident that this CaF2/NaF varnish deposits more KOH-soluble fluoride on the surface of demineralized enamel than other varnishes, but after 5 days fluoride retention is similar to that from other varnishes.
