Abstract
BACKGROUND Multimodal treatment of newly diagnosed high-risk neuroblastoma (HRNB) includes induction chemotherapy, consolidation with myeloablative therapy (MAT) and autologous stem cell transplantation (ASCT), followed by anti-disialoganglioside 2 (GD2) immunotherapy, as recommended by the Children's Oncology Group (COG) and the Society of Paediatric Oncology European Neuroblastoma (SIOPEN). Some centres proposed an alternative approach with induction chemotherapy followed by anti-GD2 immunotherapy, without MAT+ASCT. OBJECTIVE The aim of this systematic literature review was to compare survival outcomes in patients with HRNB treated with or without MAT+ASCT and with or without subsequent anti-GD2 immunotherapy. PATIENTS AND METHODS The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. MEDLINE via PubMed and EMBASE databases were systematically searched for randomised controlled trials (RCT) and observational comparative studies in patients with HRNB using search terms for 'neuroblastoma' and ('myeloablative therapy' OR 'stem cell transplantation'). Reporting of at least one survival outcome [event-free survival (EFS), progression-free survival, relapse-free survival and/or overall survival (OS)] was required for inclusion. Outcomes from RCTs were synthesized in meta-analysis, while meta-analysis of non-RCTs was not planned owing to expected heterogeneity. RESULTS Literature searches produced 2587 results with 41 publications reporting 34 comparative studies included in the review. Of these, 7 publications reported 4 RCTs, and 34 publications reported 30 non-RCT studies. Studies differed with respect to included populations, induction regimen, response to induction, additional treatments and transplantation procedures. Subsequent treatments of relapse were rarely reported and could not be compared. In the meta-analysis, EFS was in favour of MAT+ASCT over conventional chemotherapy or no further treatment [hazard ratio (HR) = 0.78, 95% confidence interval (CI) 0.67-0.91, p = 0.001] with a trend favouring MAT+ASCT for OS (HR = 0.86, 95% CI 0.73-1.00, p = 0.05). Tandem MAT+ASCT was found to improve EFS compared with the single procedure, with improvement in both EFS and OS in patients treated with anti-GD2 therapy. Non-RCT comparative studies were broadly consistent with evidence from the RCTs; however, not all reported survival benefits of MAT+ASCT (single or tandem). Limited comparative evidence on treatment without MAT+ASCT in patients treated with anti-GD2 immunotherapy suggests an increased risk of relapse. In relapsed patients, MAT+ASCT appears to improve OS, but evidence remains scarce. CONCLUSIONS Survival benefits in patients treated with MAT+ASCT confirm that the procedure should remain an integral part of multimodal therapy. In patients treated with anti-GD2 immunotherapy, limited evidence suggests that omitting MAT+ASCT is associated with an increased risk of relapse, and therefore, a change in clinical practice can currently not be recommended. Evidence suggests the use of tandem MAT+ASCT compared with the single procedure, with greater benefits observed in patients treated with anti-GD2 immunotherapy. Limited evidence also suggests improved survival following MAT+ASCT in relapsed patients, which needs to be viewed in light of emerging chemoimmunotherapy in this setting.

Technical Implications of the Chicken Embryo Chorioallantoic Membrane Assay to Elucidate Neuroblastoma Biology. Int J Mol Sci 2023; 24:14744. [PMID: 37834193 PMCID: PMC10572838 DOI: 10.3390/ijms241914744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 09/23/2023] [Accepted: 09/27/2023] [Indexed: 10/15/2023] Open
Abstract
The chorioallantoic membrane (CAM) can be used as a valuable research tool to examine tumors. The CAM can be used to investigate processes such as migration, invasion, and angiogenesis and to assess novel antitumor drugs. The CAM can be used to establish tumors in a straightforward, rapid, and cost-effective manner via xenotransplantation of cells or tumor tissues with reproducible results; furthermore, the use of the CAM adheres to the three "R" principle, i.e., replace, reduce, and refine. To achieve successful tumor establishment and survival, several technical aspects should be taken into consideration. The complexity and heterogeneity of diseases including neuroblastoma and cancers in general and their impact on human health highlight the importance of preclinical models that help us describe tumor-specific biological processes. These models will not only help in understanding tumor biology, but also allow clinicians to explore therapeutic alternatives that will improve current treatment strategies. In this review, we summarize the technical characteristics as well as the main findings regarding the use of this model to study neuroblastoma for angiogenesis, metastasis, drug sensitivity, and drug resistance.

Ann Surg Treat Res 2023; 105:148-156. [PMID: 37693287 PMCID: PMC10485353 DOI: 10.4174/astr.2023.105.3.148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 06/29/2023] [Accepted: 07/17/2023] [Indexed: 09/12/2023] Open
Abstract
Purpose Elevated plasma D-dimer level is a poor prognostic factor for many solid tumors. However, limited research has been conducted on D-dimer in children with neuroblastoma (NB), and its clinical significance remains unclear. The present study investigated the clinical and prognostic significance of D-dimer in pediatric NB patients. Methods A retrospective analysis of all newly admitted NB patients was conducted from January 2014 to December 2020. Baseline clinicopathological features, preoperative laboratory parameters, and follow-up information were collected. Univariate and multivariate analyses were performed to determine the relationship between D-dimer level, clinical features, and the prognostic value. Results Among 266 patients, the median value of D-dimer was 2.98 ng/mL, of which 132 patients showed elevated D-dimer levels before surgery (>2.98 ng/mL). Univariate analysis revealed that elevated D-dimer was significantly associated with age, hemoglobin, neutrophil-to-lymphocyte ratio, neuron-specific enolase, 24-hour vanillylmandelic acid, overall survival, and so on (P < 0.05). Patients with elevated D-dimer levels had shorter median overall survival time when compared with normal D-dimer levels (P = 0.01). The prognosis was better in patients with normal D-dimer levels when combined with lower age, ganglioneuroblastoma tumor type, lower stage on International Neuroblastoma Staging System, low-risk group, and without bone metastasis or bone marrow metastasis. The continuous increase of D-dimer level after treatment indicated tumor recurrence or progression. Conclusion A high D-dimer level is associated with low overall survival, and an elevated D-dimer level after treatment indicates tumor recurrence and progression. D-dimer can be used as one of the evaluation factors for NB treatment or prognosis.

Abstract
Existing literature on febrile neutropenia (FN) has categorized patients with acute leukemia or those undergoing allogeneic stem cell transplantation (SCT) as being high risk for severe infection, bacteremia, and poor outcomes. Comprehensive studies of infection risk in pediatric high-risk neuroblastoma (NB-HR) during induction chemotherapy are limited, and mostly merged within the solid tumor (ST) group. Therefore, it is unclear whether infectious complications and outcomes for NB-HR are the same as in other ST groups. We conducted a retrospective medical record review of pediatric FN patients in a single center from March 2009 to December 2016. FN episodes were categorized into five groups based on underlying diagnosis (acute myelogenous leukemia (AML), acute lymphocytic leukemia (ALL), NB-HR during induction chemotherapy, other solid tumors, and SCT). Comparative analyses of infectious complications between patients with NB-HR and those with other types of cancer diagnoses were performed. A total of 667 FN episodes (FNEs) were identified in 230 patients. FNEs occurred in 82 episodes with NB-HR. Bloodstream infection (BSI) occurred in 145 (21.7%) of total FN episodes. The most isolated organisms were the viridians group streptococci (VGS) (25%). NB-HR patients have higher rates of VGS bacteremia (OR 0.15, 95% [CI 0.04, 0.56]) and are more likely to be admitted to the Pediatric Intensive Care Unit (PICU) compared to patients with other solid tumors (OR 0.36, 95% [CI 0.15, 0.84]). Interestingly, there is no difference in VGS rates between patients with NB-HR and those with AML despite the fact that NB-HR patients do not receive a cytosine arabinoside (AraC)-based regimen. This large neuroblastoma cohort showed that patients with NB-HR during induction chemotherapy are at higher risk for VGS bacteremia and PICU admissions compared with patients with other solid tumors. Further prospective studies are needed to investigate infection-related complications in this high-risk group and to improve morbidity and mortality.

Abstract
Neuroblastoma is the most common and deadliest tumor in infancy. WDR5 (WD Repeat Domain 5), a critical factor supporting an N-myc transcriptional complex via its WBM site and interacting with chromosome via its WIN site, promotes the progression of neuroblastoma, thus making it a potential anti-neuroblastoma drug target. So far, a few WIN site inhibitors have been reported, and the WBM site disruptors are rare to see. In this study we conducted virtual screening to identify candidate hit compounds targeting the WBM site of WDR5. As a result, 60 compounds were selected as candidate WBM site inhibitors. Cell proliferation assay demonstrated 6 structurally distinct WBM site inhibitors, numbering as compounds 4, 7, 11, 13, 19 and 22, which potently suppressed 3 neuroblastoma cell lines (MYCN-amplified IMR32 and LAN5 cell lines, and MYCN-unamplified SK-N-AS cell line). Among them, compound 19 suppressed the proliferation of IMR32 and LAN5 cells with EC50 values of 12.34 and 14.89 μM, respectively, and exerted a moderate inhibition on SK-N-AS cells, without affecting HEK293T cells at 20 μM. Analysis of high-resolution crystal complex structure of compound 19 against WDR5 revealed that it competitively occupied the hydrophobic pocket where V264 was located, which might disrupt the interaction of MYC with WDR5 and further MYC-medicated gene transcription. By performing RNA-seq analysis we demonstrated the differences in molecular action mechanisms of the compound 19 and a WIN site inhibitor OICR-9429. Most interestingly, we established the particularly high synergy rate by combining WBM site inhibitor 19 and the WIN site inhibitor OICR-9429, providing a novel therapeutic avenue for neuroblastoma.

Abstract
PURPOSE To induce the expression of Amphinase, an antitumor ribonuclease from Rana pipiens oocytes, in neuroblastoma cell lines and build a foundation for mechanism study. METHODS A loxP-cassette vector was constructed comprising a sequence of loxP -Puro-3∗polyA-loxP, followed by amphinase cDNA. The vector was transfected into neuroblastoma cell lines, SK-N-BE(2)-C, by Lipofectamine LTX. The transfected cells were selected by puromycin for two weeks. Polymerase chain reaction (PCR) and real-time quantitative PCR (qPCR) were conducted to verify that the loxP-cassette vector was stably transfected. The expression of amphinase was activated by the addition of Cre recombinase delivered by a lentiviral vector and identified by qPCR and Western blotting (WB). CCK8 assay and colony formation assay were conducted to check the effect of amphinase on cell proliferation. RNA sequencing (RNA-seq) was conducted to explore the targeted pathway of Cre/loxP-mediated amphinase and recombinant amphinase. RESULTS Stably transfected cell clones were achieved through puromycin selection. After Cre recombinase was delivered to the cells, the loxP-flanked fragment was deleted and the expression of amphinase was induced, which were tested by PCR and qPCR. It was shown that cell proliferation was significantly inhibited by the amphinase mediated by the Cre/loxP system. KEGG enrichment and GSEA analysis indicated that amphinase had an impact on the ER function of neuroblastoma cells, which was identical to the effect of the recombinant amphinase. CONCLUSION We successfully induce the expression of amphinase in neuroblastoma cell lines via Cre/loxP system. The Cre/loxP-mediated amphinase had a similar antitumor mechanism to the recombinant amphinase, providing a powerful tool for the mechanism study of amphinase.

Abstract
Neuroblastoma is a common solid tumor in children and a leading cause of cancer death in children. Neuroblastoma exhibits genetic, morphological, and clinical heterogeneity that limits the efficacy of current monotherapies. With further research on neuroblastoma, the pathogenesis of neuroblastoma is found to be complex, and more and more treatment therapies are needed. The importance of personalized therapy is growing. Currently, various molecular features, including RAS mutations, are being used as targets for the development of new therapies for patients with neuroblastoma. A recent study found that RAS mutations are frequently present in recurrent neuroblastoma. RAS mutations have been shown to activate the MAPK pathway and play an important role in neuroblastoma. Treating RAS mutated neuroblastoma is a difficult challenge, but many preclinical studies have yielded effective results. At the same time, many of the therapies used to treat RAS mutated tumors also have good reference values for treating RAS mutated neuroblastoma. The success of KRAS-G12C inhibitors has greatly stimulated confidence in the direct suppression of RAS. This review describes the biological role of RAS and the frequency of RAS mutations in neuroblastoma. This paper focuses on the strategies, preclinical, and clinical progress of targeting carcinogenic RAS in neuroblastoma, and proposes possible prospects and challenges in the future.

Abstract
Garlic (Allium sativum) has been used in alternative medicine to treat several diseases, such as cardiovascular and neurodegenerative diseases, cancer, and hepatic diseases. Several publications have highlighted other features of garlic, including its antibacterial, antioxidative, antihypertensive, and antithrombotic properties. The properties of garlic result from the combination of natural compounds that act synergistically and cause different effects. Some garlic-derived compounds have been studied for the treatment of several types of cancer; however, reports on the effects of garlic on neuroblastoma are scarce. Neuroblastoma is a prevalent childhood tumor for which the search for therapeutic alternatives to improve treatment without affecting the patients’ quality of life continues. Garlic-derived compounds hold potential for the treatment of this type of cancer. A review of articles published to date on some garlic compounds and their effect on neuroblastoma was undertaken to comprehend the possible therapeutic role of these compounds. This review aimed to analyze the impact of some garlic compounds on cells derived from neuroblastoma.

[PMID: 32735384 DOI: 10.1002/pbc.28301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2019] [Revised: 03/15/2020] [Accepted: 03/16/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND Quality indicators (QIs) may be used to monitor the quality of neuroblastoma (NBL) care during treatment, in addition to survival and treatment toxicity, which can only be evaluated in the years after treatment. The present study aimed to assess the feasibility of a new set of indicators for the quality of NBL therapy. PROCEDURE Seven QIs have been proposed based on literature and consensus of experts: (a) duration of complete diagnostic work-up, (b) prescription of thyroid prophylaxis before metaiodobenzylguanidine imaging, (c) treatment intensity, (d) use of tumor board meetings, (e) number of outpatient visits and sedation procedures during follow-up, (f) protocolled follow-up, and (g) required apheresis sessions. A retrospective data analysis from October 2014 to November 2017 including all patients with NBL in the centralized Princess Máxima Center in the Netherlands was performed to assess these parameters and determine practicality of measurement. RESULTS A total number of 72 patients (aged between 2 weeks and 15 years) were analyzed. Adherence to all QIs could be determined for all eligible patients using their electronic medical records. Three indicators were compared over time, and an increase in adherence was observed. CONCLUSIONS Assessment of QIs in neuroblastoma treatment is feasible. Seven new QIs were found to be feasible to measure and showed improvement over time for three indicators. Monitoring of these QIs during treatment may provide tools for quality improvement activities and comparisons of treatment quality over time or between centers. Further study is required to investigate their association with long-term outcomes.

Abstract
There is an urgent need to identify novel therapies for childhood cancers. Neuroblastoma is the most common pediatric solid tumor, and accounts for ~15% of childhood cancer‐related mortality. Neuroblastomas exhibit genetic, morphological and clinical heterogeneity, which limits the efficacy of existing treatment modalities. Gaining detailed knowledge of the molecular signatures and genetic variations involved in the pathogenesis of neuroblastoma is necessary to develop safer and more effective treatments for this devastating disease. Recent studies with advanced high‐throughput “omics” techniques have revealed numerous genetic/genomic alterations and dysfunctional pathways that drive the onset, growth, progression, and resistance of neuroblastoma to therapy. A variety of molecular signatures are being evaluated to better understand the disease, with many of them being used as targets to develop new treatments for neuroblastoma patients. In this review, we have summarized the contemporary understanding of the molecular pathways and genetic aberrations, such as those in MYCN, BIRC5, PHOX2B, and LIN28B, involved in the pathogenesis of neuroblastoma, and provide a comprehensive overview of the molecular targeted therapies under preclinical and clinical investigations, particularly those targeting ALK signaling, MDM2, PI3K/Akt/mTOR and RAS‐MAPK pathways, as well as epigenetic regulators. We also give insights on the use of combination therapies involving novel agents that target various pathways. Further, we discuss the future directions that would help identify novel targets and therapeutics and improve the currently available therapies, enhancing the treatment outcomes and survival of patients with neuroblastoma.

Abstract
High-risk neuroblastoma (HR-NB) includes MYCN-amplified stage 2/3, but reports covering anti-GD2 immunotherapy, which recently became standard for HR-NB, do not provide details on this subset. We now report on all 20 MYCN-amplified stage 2/3 patients who received induction chemotherapy at our center during the era of consolidation with anti-GD2 antibody 3F8/ granulocyte-macrophage colony-stimulating factor (GM-CSF) (2000-2015). Early in this period, consolidation included autologous stem-cell transplantation (ASCT). Event-free survival (EFS) and overall survival (OS) were estimated using Kaplan-Meier analyses. With induction, 19/20 (95%) patients achieved complete/very good partial remission (CR/VGPR) but one had progressive disease with early death. One responder did not receive consolidation and died of relapse. Five-year post-diagnosis EFS/OS rates for all 20 patients were 72%/84%. The 18 CR/VGPR patients who received consolidation had EFS/OS 81%/94% at five years from starting 3F8/GM-CSF: 4/4 ASCT patients remained relapse-free, while 11/14 non-ASCT patients remained relapse-free and two of the three relapsed patients achieved 2nd CR (consolidated by retreatment with 3F8/GM-CSF) and remained in 2nd CR at 36+ and 95+ months post-relapse. The 14 non-ASCT patients had EFS/OS 73.5%/93% at five years from starting 3F8/GM-CSF. This subset appears to have a good prognosis with contemporary multi-modality therapy, possibly even without ASCT.

Abstract
INTRODUCTION Neuroblastoma is the most common solid extracranial tumor of childhood. Outcome for children with high-risk neuroblastoma remains suboptimal. More than half of children diagnosed with high-risk neuroblastoma either do not respond to conventional therapies or relapse after treatment with dismal prognosis. Areas covered: This paper presents a short review of the state of the art in the current treatment of high-risk neuroblastoma. An updated review of new targeted therapies in this group of patients is also presented. Expert opinion: In order to improve prognosis for high-risk patients there is an urgent need to better understand spatial and temporal heterogeneity and obtain new predictive preclinical models in neuroblastoma. Combination strategies with conventional chemotherapy and/or other targeted therapies may overcome current ALK inhibitors resistance. Improvement of international and transatlantic cooperation to speed clinical trials accrual is needed.

Abstract
Since 2003, high-risk neuroblastoma (HR-NB) patients at our center received anti-GD2 antibody 3F8/GM-CSF + isotretinoin – but not myeloablative therapy with autologous stem-cell transplantation (ASCT). Post-ASCT patients referred from elsewhere also received 3F8/GM-CSF + isotretinoin. We therefore accrued a study population of two groups treated during the same period and whose consolidative therapy, aside from ASCT, was identical. We analyzed patients enrolled in 1st complete/very good partial remission (CR/VGPR). Their event-free survival (EFS) and overall survival (OS) were calculated from study entry. Large study size allowed robust statistical analyses of key prognosticators including MYCN amplification, minimal residual disease (MRD), FCGR2A polymorphisms, and killer immunoglobulin-like receptor genotypes of natural killer cells. The 170 study patients included 60 enrolled following ASCT and 110 following conventional chemotherapy. The two cohorts had similar clinical and biological features. Five-year rates for ASCT and non-ASCT patients were, respectively: EFS 65% vs. 51% (p = .128), and OS 76% vs. 75% (p = .975). In multivariate analysis, ASCT was not prognostic and only MRD-negativity after two cycles of 3F8/GM-CSF correlated with significantly improved EFS and OS. Although a trend towards better EFS is seen with ASCT, OS is near identical. Cure rates may be similar, as close surveillance detects localized relapse and effective salvage treatments are applied. ASCT may not be needed to improve outcome when anti-GD2 immunotherapy is used for consolidation after dose-intensive conventional chemotherapy.

Abstract
BACKGROUND Despite the development of new treatment options, the prognosis of high-risk neuroblastoma patients is still poor; more than half of patients experience disease recurrence. High-dose chemotherapy and haematopoietic stem cell rescue (i.e. myeloablative therapy) might improve survival. This review is the second update of a previously published Cochrane review. OBJECTIVES Primary objectiveTo compare the efficacy, that is event-free and overall survival, of high-dose chemotherapy and autologous bone marrow or stem cell rescue with conventional therapy in children with high-risk neuroblastoma. Secondary objectivesTo determine adverse effects (e.g. veno-occlusive disease of the liver) and late effects (e.g. endocrine disorders or secondary malignancies) related to the procedure and possible effects of these procedures on quality of life. SEARCH METHODS We searched the electronic databases The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, issue 11), MEDLINE/PubMed (1966 to December 2014) and EMBASE/Ovid (1980 to December 2014). In addition, we searched reference lists of relevant articles and the conference proceedings of the International Society for Paediatric Oncology (SIOP) (from 2002 to 2014), American Society for Pediatric Hematology and Oncology (ASPHO) (from 2002 to 2014), Advances in Neuroblastoma Research (ANR) (from 2002 to 2014) and American Society for Clinical Oncology (ASCO) (from 2008 to 2014). We searched for ongoing trials by scanning the ISRCTN register (www.isrct.com) and the National Institute of Health Register (www.clinicaltrials.gov). Both registers were screened in April 2015. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing the efficacy of myeloablative therapy with conventional therapy in high-risk neuroblastoma patients. DATA COLLECTION AND ANALYSIS Two authors independently performed study selection, data extraction and risk of bias assessment. If appropriate, we pooled studies. The risk ratio (RR) and 95% confidence interval (CI) was calculated for dichotomous outcomes. For the assessment of survival data, we calculated the hazard ratio (HR) and 95% CI. We used Parmar's method if hazard ratios were not reported in the study. We used a random-effects model. MAIN RESULTS We identified three RCTs including 739 children. They all used an age of one year as the cut-off point for pre-treatment risk stratification. The first updated search identified a manuscript reporting additional follow-up data for one of these RCTs, while the second update identified an erratum of this study. There was a significant statistical difference in event-free survival in favour of myeloablative therapy over conventional chemotherapy or no further treatment (three studies, 739 patients; HR 0.78, 95% CI 0.67 to 0.90). There was a significant statistical difference in overall survival in favour of myeloablative therapy over conventional chemotherapy or no further treatment (two studies, 360 patients; HR 0.74, 95% CI 0.57 to 0.98). However, when additional follow-up data were included in the analyses the difference in event-free survival remained statistically significant (three studies, 739 patients; HR 0.79, 95% CI 0.70 to 0.90), but the difference in overall survival was no longer statistically significant (two studies, 360 patients; HR 0.86, 95% CI 0.73 to 1.01). The meta-analysis of secondary malignant disease and treatment-related death did not show any significant statistical differences between the treatment groups. Data from one study (379 patients) showed a significantly higher incidence of renal effects, interstitial pneumonitis and veno-occlusive disease in the myeloablative group compared to conventional chemotherapy, whereas for serious infections and sepsis no significant difference between the treatment groups was identified. No information on quality of life was reported. In the individual studies we evaluated different subgroups, but the results were not univocal in all studies. All studies had some methodological limitations. AUTHORS' CONCLUSIONS Based on the currently available evidence, myeloablative therapy seems to work in terms of event-free survival. For overall survival there is currently no evidence of effect when additional follow-up data are included. No definitive conclusions can be made regarding adverse effects and quality of life, although possible higher levels of adverse effects should be kept in mind. A definitive conclusion regarding the effect of myeloablative therapy in different subgroups is not possible. This systematic review only allows a conclusion on the concept of myeloablative therapy; no conclusions can be made regarding the best treatment strategy. Future trials on the use of myeloablative therapy for high-risk neuroblastoma should focus on identifying the most optimal induction and/or myeloablative regimen. The best study design to answer these questions is a RCT. These RCTs should be performed in homogeneous study populations (e.g. stage of disease and patient age) and have a long-term follow-up. Different risk groups, using the most recent definitions, should be taken into account.It should be kept in mind that recently the age cut-off for high risk disease was changed from one year to 18 months. As a result it is possible that patients with what is now classified as intermediate-risk disease have been included in the high-risk groups. Consequently the relevance of the results of these studies to the current practice can be questioned. Survival rates may be overestimated due to the inclusion of patients with intermediate-risk disease.

Abstract
The role of surgery in the management of advanced staged neuroblastoma (NBL) is controversial. A systematic review and meta-analysis is reported to address robust evidence for curative "gross total tumor resection" (GTR) in Stage 3 and Stage 4 neuroblastoma. Studies were identified using Medline, Embase, and Cochrane databases using pre-specified search terms. Primary outcomes were 5-year overall (OS) and disease-free survival (DFS) after GTR and subtotal resection (STR) in Stage 3 or 4 NBL. Data were analyzed using Review Manager. The Mantel-Haenszel method and a random effects model was utilized to calculate odds ratios (95% CI). Fifteen studies (five Stage 3 and 13 Stage 4) met full inclusion criteria. The pooled odds ratio for 5 year OS in Stage 3 following GTR compared to STR was 2.4 (95% CI 1.19-4.85). In Stage 4 disease, the pooled odds ratio for 5 year overall survival (OS) following GTR compared to STR was 1.65 (95% CI 0.96-1.91); a pooled odds ratio for 5 year DFS following GTR compared to STR was 1.55 (95% CI 1.12-2.14). A clear survival benefit is shown for GTR over STR in Stage 3 NBL only. Though some advantage can be demonstrated for GTR as defined by DFS in Stage 4 NBL GTR did not significantly improve OS in Stage 4 disease.

Abstract
BACKGROUND The authors exploited a large database to investigate the outcomes of patients with high-risk neuroblastoma in the contemporary era. METHODS All patients with high-risk neuroblastoma aged <12 years who were treated during induction at the authors' institution from 2000 through 2011 were studied, including 118 patients with MYCN-amplified [MYCN(+)] disease and 127 patients aged >18 months with MYCN-nonamplified [MYCN(-)] stage 4 disease. RESULTS A complete response/very good partial response (CR/VGPR) to induction was correlated with significantly superior event-free survival (EFS) (P < .001) and overall survival (OS) (P < .001) compared with a partial response or less. Patients with MYCN(+) and MYCN(-) disease had similar rates of CR/VGPR to induction (P = .366), and those with MYCN(+) and MYCN(-) disease who attained a CR/VGPR had similar EFS (P = .346) and OS (P = .542). In contrast, only MYCN(+) patients had progressive disease as a response to induction (P < .001), and early death from progressive disease (<366 days after diagnosis) was significantly more common (P < .001) among those with MYCN(+) disease. Overall, among patients who had a partial response or less, MYCN(+) patients had significantly inferior EFS (P < .001) and OS (P < .001) compared with MYCN(-) patients, which accounted for the significantly worse EFS (P = .008) and OS (P = .002) for the entire MYCN(+) cohort versus the MYCN(-) cohort. CONCLUSIONS Patients with MYCN(-), high-risk neuroblastoma display a broad, continuous spectrum with regard to response and outcome, whereas MYCN(+) patients either have an excellent response to induction associated with good long-term outcome or develop early progressive disease with a poor outcome. This extreme dichotomy in the clinical course of MYCN(+) patients points to underlying biologic differences with MYCN(+) neuroblastoma, the elucidation of which may have far-reaching implications, including improved risk classification at diagnosis and the identification of targets for treatment.

There was a statistically significant difference in overall survival in favour of myeloablative therapy over conventional chemotherapy or no further treatment (2 studies, 360 patients; HR 0.74, 95% CI 0.57 to 0.98). However, when additional follow-up data were included in the analyses the difference in event-free survival remained statistically significant (3 studies. 739 patients; HR 0.79, 95% CI 0.70 to 0.90), but the difference in overall survival was no longer statistically significant (2 studies, 360 patients; HR 0.86, 95% CI 0.73 to 1.01). The meta-analysis of secondary malignant disease and treatment-related death did not show any statistically significant differences between the treatment groups. Data from one study (379 patients) showed a significantly higher incidence of renal effects, interstitial pneumonitis and veno-occlusive disease in the myeloablative group compared to conventional chemotherapy, whereas for serious infections and sepsis no significant difference between the treatment groups was identified. No information on quality of life was reported. In the individual studies we evaluated different subgroups, but the results were not univocal in all studies. All studies had some methodological limitations. AUTHORS' CONCLUSIONS Based on the currently available evidence, myeloablative therapy seems to work in terms of event-free survival. For overall survival there is currently no evidence of effect when additional follow-up data are included. No definitive conclusions can be made regarding adverse effects and quality of life, although possible higher levels of adverse effects should be kept in mind. A definitive conclusion regarding the effect of myeloablative therapy in different subgroups is not possible. This systematic review only allows a conclusion on the concept of myeloablative therapy; no conclusions can be made regarding the best treatment strategy. Future trials on the use of myeloablative therapy for high-risk neuroblastoma should focus on identifying the most optimal induction and/or myeloablative regimen. The best study design to answer these questions is a RCT. These RCTs should be performed in homogeneous study populations (e.g. stage of disease and patient age) and have a long-term follow-up. Different risk groups, using the most recent definitions, should be taken into account.It should be kept in mind that recently the age cut-off for high risk disease was changed from one year to 18 months. As a result it is possible that patients with what is now classified as intermediate-risk disease have been included in the high-risk groups. Consequently the relevance of the results of these studies to the current practice can be questioned. Survival rates may be overestimated due to the inclusion of patients with intermediate-risk disease.

Abstract
INTRODUCTION Neuroblastoma accounts for 8 - 10% of pediatric cancers and is responsible for 15% of childhood cancer deaths. Despite multimodality treatment, the overall survival (OS) and event-free survival (EFS) in high-risk patients remain suboptimal. More than half of children diagnosed with high-risk neuroblastoma either do not respond to conventional therapies or relapse after treatment. AREAS COVERED This review discusses about the unmet medical needs for new therapeutic options against high-risk neuroblastoma. New drugs and therapeutic strategies that are under development in clinical trials, which are currently recruiting patients. EXPERT OPINION There is a need to improve the response rate of induction chemotherapy, which is not effective in a third of patients and also the other components of the current treatment, little efficacious in avoiding the relapses. Few drugs have been introduced as upfront therapy in the last years. Topotecan, irinotecan and temozolomide are expected to improve the response in high-risk neuroblastoma, but their impact on OS and EFS is unknown. Anti-GD2 antibodies combined with other immunomodulators (IL-2, GM-CSF) are an important advance in the treatment of these children. Nevertheless, the hope is put in the new drugs directed to molecular targets of neuroblastoma. Anti-angiogenic drugs, ALK antagonist and PI3K/Akt/mTOR inhibitors are among the most promising.

Abstract
BACKGROUND Outcome of high risk neuroblastoma (NBL) remains unsatisfactory in spite of intensive treatment efforts. Consolidation with high-dose (HD) chemotherapy and autologous stem cell transplantation (ASCT) has been intensified with tandem and triple cycles with promising results. Our purpose was to improve the outcome with two or three HD-consolidations. METHODS Thirty six children with high risk NBL, diagnosed 1995-2010, had intensive induction and surgery, and were stratified to single, tandem or triple HD-therapy and ASCT, followed by local irradiation and cis-retinoic acid. In inoperable patients surgery was facilitated by preoperative HD-melphalan. Long-term outcome of our old cohort from 1987-1994 was updated. RESULTS Ten year event-free survival (EFS) from diagnosis was 0.44+/-0.10 of the old and 0.43+/-0.085 of the new cohort. EFS from the last ASCT was 0.53 +/-0.12 and 0.48+/-0.091, respectively. Preoperative HD-melphalan rendered 73% of bulky primaries operable in the new cohort. The 5-yr EFS from ASCT was 0.46+/-0.15 for single and 0.73+/-0.15 for tandem ASCT (P = 0.19). All triple ASCT patients, selected by poor/slow response, relapsed or died. CONCLUSIONS Thiotepa- and melphalan based HD regimens, with or without total body irradiation (TBI), appeared to give an outcome comparable to major NBL study groups with acceptable toxicity. Tandem HD therapy gave a 5-year EFS of 73%, whereas a third HD consolidation did not offer any additional advantage for ultra high risk patients with slow response.

Abstract
BACKGROUND Despite the development of new treatment options, the prognosis of high-risk neuroblastoma patients is still poor; more than half of patients experience disease recurrence. High-dose chemotherapy and haematopoietic stem cell rescue (i.e. myeloablative therapy) might improve survival. OBJECTIVES To compare the effectiveness of myeloablative therapy with conventional therapy in children with high-risk neuroblastoma. SEARCH STRATEGY We searched CENTRAL (The Cochrane Library 2009, issue 1), MEDLINE/PubMed (1966 to January 2009) and EMBASE/Ovid (1980 to January 2009). In addition, we searched reference lists of relevant articles, conference proceedings and ongoing trial databases. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing the effectiveness of myeloablative therapy with conventional therapy in high-risk neuroblastoma patients. DATA COLLECTION AND ANALYSIS Two authors independently performed study selection, data extraction and risk of bias assessment. If possible, we pooled results. MAIN RESULTS We identified three RCTs including 739 children. The meta-analysis of event-free survival showed a significant difference in favour of the myeloablative therapy group (HR 0.78; 95% CI 0.67 to 0.90), as did the meta-analysis of overall survival (HR 0.74; 95% CI 0.57 to 0.98). The meta-analysis of secondary malignant disease and treatment-related death did not show a significant difference between the treatment groups. In one study a significant difference in favour of the conventional therapy group was identified for renal effects, interstitial pneumonitis and veno-occlusive disease, whereas for serious infections and sepsis no significant difference between the treatment groups was identified. In the individual studies we evaluated different subgroups, but the results were not univocal in all studies. All studies had some methodological limitations. AUTHORS' CONCLUSIONS Based on the currently available evidence, myeloablative therapy seems to be a good treatment option for children with high-risk neuroblastoma. It results in higher survival rates than conventional therapy, although possible higher levels of adverse effects should be kept in mind. A definitive conclusion regarding the effect of myeloablative therapy in different subgroups is not possible. This systematic review only allows a conclusion on the concept of myeloablative therapy; no conclusions can be made regarding the best treatment strategy. Future trials on the use of myeloablative therapy for high-risk neuroblastoma should focus on identifying the most optimal induction and/or myeloablative regimen. The best study design to answer these questions is a RCT. These RCTs should be performed in homogeneous study populations (for example, regarding stage of disease and patient age) and have a long-term follow up. Different risk groups should be taken into account.

Abstract
PurposeTo report the results of a prospective, nonrandomized European study on infants with neuroblastoma and MYCN gene amplification.Patients and MethodsInfants with neuroblastoma (stage 2, 3, 4, and 4s) and MYCN gene amplification who were diagnosed between 1999 and 2004 were eligible for enrollment onto the study. After diagnosis, staging, and mandatory biologic studies, induction chemotherapy (IC) with conventional drugs was administered, followed by delayed surgery, megatherapy (busulfan-melphalan as a conditioning regimen), and local radiotherapy.ResultsOf the 46 infants enrolled onto the study, 35 infants were eligible; of these 35 infants, 97% had metastatic spread (24 infants had stage 4, and 10 infants had stage 4s). Two-year overall survival (OS) was 30% (SE, 0.08), with median survival time of 12 months, and 23 deaths due to disease. Two-year, event-free survival (EFS) was 29% (SE, 0.07). The treatment was well tolerated with no deaths as a result of toxicity or severe toxicity. Despite protocol adherence, 30% of the patients who were assessable for response to IC experienced disease progression or did not respond. Stage and high lactate dehydrogenase reached significance in the univariate analysis (P = .028 and .039, respectively for OS; and P = .05 and .031 respectively, for EFS). Ten of 16 patients who received megatherapy are still alive.ConclusionAlthough treatment was well tolerated, survival was poor and our IC failed to achieve a satisfactory response in 30% of our patients. New therapeutic approaches and more intense world-wide collaboration are needed to achieve a cure in this population.

Abstract
Carboplatin is a well-established chemotherapeutic agent used to treat a variety of pediatric malignancies. Platinum analogues such as cisplatin are known to be ototoxic, but little is known regarding the ototoxicity of carboplatin. We performed a single institution retrospective chart review of pediatric oncology patients who received platinum-containing regimens from 1993 to 2002. Ninety-nine patients with sufficient medical and audiologic data were identified. Significant hearing loss was defined as a Brock grade 1 or higher. The incidence was compared among 3 treatment groups (carboplatin only, carboplatin and cisplatin, and cisplatin only). Significant hearing loss in patients receiving carboplatin only was rare, observed in only 1/25 (4%) of patients. In contrast, 19/27 (70%) of patients receiving carboplatin and cisplatin possessed significant hearing loss, as did 27/47 (57%) of those patients receiving cisplatin only P<0.001. The difference in hearing loss could not be explained by different cumulative exposures of the platinum agents. Carboplatin, when used without cisplatin, is rarely associated with severe hearing loss, even at high cumulative doses.

Abstract
We have previously described the identification of a nucleoside analog transcriptional inhibitor ARC (4-amino-6-hydrazino-7-beta-D-ribofuranosyl-7H-pyrrolo[2,3-d]-pyrimidine-5-carboxamide) that was able to induce apoptosis in cancer cell lines of different origin. Here, we report the characterization of ARC on a panel of neuroblastoma cell lines. We found that these cell lines were more than 10-fold sensitive to ARC than to the well-known nucleoside analog DRB (5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole), and that ARC-induced apoptosis proceeds through mitochondrial injury. Also, we observed that ARC-mediated cell death was accompanied by caspase-3 cleavage and repression of antiapoptotic proteins such as Mcl-1 and survivin. Conversely, we found that overexpression of Mcl-1-protected neuroblastoma cell line NB-1691 from ARC-induced apoptosis. Furthermore, we found that while ARC inhibited the phosphorylation of Akt Ser-473 in multiple cancer cell lines, forced expression of myristoylated Akt promoted resistance to ARC-induced apoptosis in neuroblastoma cells. In addition, we observed that ARC was able to downregulate the protein levels of N-myc, a commonly amplified oncogene in neuroblastomas, and Akt protected N-myc from ARC-induced downregulation. These data suggest that ARC may antagonize different antiapoptotic pathways and induce apoptosis in neuroblastoma cells via multiple mechanisms. Overall, ARC could represent an attractive candidate for anticancer drug development against neuroblastomas.

Abstract
We retrospectively analysed the outcomes of children transplanted for high-risk neuroblastoma (NB) at a single institution predominantly transplanted with total body irradiation and chemotherapy. The aims of this study were to determine the prognostic impact of clinical and biological features and to document long-term health outcomes. Forty patients were transplanted with a single unpurged autograft. Fourteen patients died from disease progression and two from late complications of treatment. Twenty-three patients are alive at a median of 4.6 years from diagnosis. Kaplan-Meier estimates of overall survival at 2, 5 and 10 years are 76+/-7.0, 60.2+/-8.4 and 54.7+/-9.3% following transplant. Response to induction therapy was significantly associated with survival (P<0.01). Long-term complications included growth (100%) and pubertal failure (83%), hearing impairment (73%), orthopaedic complications (63%), renal impairment (47%) and thyroid abnormalities (36%). Intrinsic and acquired resistance to chemotherapy remains the major obstacle to improving outcomes in high-risk NB. Although patients with chemo-sensitive disease are less likely to experience a relapse, substantial therapy-related toxicities result in poor long-term health outcomes for survivors.

Abstract
The Automated Childhood Cancer Information System (ACCIS) collects and presents data on childhood cancer in Europe. This report describes trends (1978-1997) and geographical differences (1988-1997) in incidence and survival for 6202 children with neuroblastoma from 59 registries in 19 countries, grouped into five regions (British Isles, West, East, North, and South). The age-standardised incidence rate (ASR) of neuroblastoma in Europe in 1988-1997 was 10.9 cases per million children, being highest in infants (52.6). The ASR of neuroblastoma increased in Europe from 8.4 in 1978-1982 to 11.6 in 1993-1997, mostly due to an increase in infants (from 35.4 to 57.8). Overall 5-year survival was 59%, ranging from 47% (East) to 67% (West). It improved markedly from 37% in 1978-1982 to 66% in 1993-1997, especially in infants. A certain amount of overdiagnosis in children under 2 years of age may explain the increased incidence rates and partially the increase in survival. Survival of older children (aged 2-14 years), which is likely to be largely affected by therapy, has also improved from 21% to 45%.

Abstract
Different subtypes of neuroblastoma (NB) carry associated genetic aberrations that predict their clinical course. Whole chromosome gains are usually associated with early clinical stages and good prognosis, while 1p deletion, 17q gain and MYCN amplification (MNA) are related to advanced stages and poor prognosis. High-risk neuroblastomas (NB-HR) include NB in children aged more than 1 year old, either stage 4 or any stages showing MNA except stage 1. The prognosis of NB-HR patients remains poor, despite aggressive therapy. Only MNA confers poor prognosis. Between January 2000 and February 2005, tumoral specimens from 60 patients with NB-HR were sent to the Spanish Reference Center for NB biological studies. In all cases, MYCN together with 1p36 status was analyzed by fluorescence in situ hybridization (FISH). Comparative genomic hybridization (CGH) was performed in 24 cases. Using FISH we detected 31 MNA cases including 29 with 1p36 deletion; there were 21 cases without MYCN amplification (MNNA) but 7 of these had 1p36 deletion; 8 cases showed MYCN gain (MNG) but 6 of these had 1p36 deletion. CGH showed other chromosomal alterations. Of 11 MNA cases, none had 11q loss and all of them showed 17q gain or 17 disomy. Of the 7 MNNA cases, there were 4 with 11q loss including 2 with 3p loss and all presented 17q gain or 17 disomy. The 6 MNG cases included 4 cases with 11q loss and 5 cases with 17q gain or 17 disomy. Genomic profiling by CGH in NB-HR confirms the interaction among genetic alterations, the prognostic significance of which should be evaluated to establish new treatment criteria.

Abstract
BACKGROUND High-risk neuroblastoma (NB; age, >1 year; INSS stage 4) is associated with a poor outcome. At our institution, the current dose-intensive high-risk Children's Oncology Group protocol for advanced NB appears to have a higher surgical complication rate as compared with previous protocols. METHODS All stage 4 patients (n = 51) entered in high-risk protocols between 1995 and 2005 were analyzed. Patients in the current high-risk protocol, Children's Oncology Group A3973 (n = 22), were compared with those in the 2 previous protocols, CCG 3891 and POG 9341 (n = 29). RESULTS Patients were comparable in their mean age and tumor markers, including Shimada histology, MYCN amplification, 1p deletion, tumor origin, and extent of metastasis. However, transfusion requirement (86% vs 45%; P = .0019), postoperative infection rate (32% vs 3%; P = .02), and other postoperative issues including nutritional support (45% vs 3%; P = .0001) were significantly higher with the current protocol. No perioperative mortality was noted in either group, and the extent of resectability and margins were similar. Importantly, with the current protocol, the survival rate was higher (P = .0022) and the recurrence rate was significantly lower (P = .0003). CONCLUSIONS Despite higher surgical morbidity associated with the current high-risk protocol (2.59 vs 0.86 complications/person; P < .01), the recurrence rate is lower and interim survival rate is improved for patients with high-risk NB. Therefore, the higher surgical complication rates associated with the current high-risk protocol are acceptable.

Abstract
BACKGROUND It remains unclear whether primary tumor resection benefits patients with metastatic neuroblastoma. The authors assessed the impact of extent and timing of resection on outcome in these patients. METHODS The authors reviewed the records of 124 patients > 1 year of age at diagnosis of International Neuroblastoma Staging System Stage 4 neuroblastoma. The survival estimates of those who did and did not have a gross total resection (GTR) and of those who had initial versus delayed GTR were compared. Surgical complications were reviewed. RESULTS The 5-year survival estimates were comparable for the 90 patients who had a GTR and the 17 who underwent surgery but did not have a GTR (29.9% +/- 5.1% [standard error] vs. 29.4% +/- 10.1%). The 7 patients who underwent GTR at the time of diagnosis had a higher 5-year survival estimate than the 83 patients who had a GTR after induction chemotherapy (83.3% +/- 13.9% vs. 25.2% +/- 5.0%) (P = 0.001). Five-year event-free survival estimates were similarly higher in the initial-GTR group (57.1% +/- 18.7% vs. 14.5% +/- 4.2%) (P = 0.002). These two groups did not differ significantly in age at diagnosis (P = 0.118), site of primary tumor (P = 0.34), MYCN amplification status (P = 1), serum lactate dehydrogenase activity at diagnosis (P = 0.34), or treatment protocol (P = 0.22). Twenty-two (21%) patients had a surgical complication. CONCLUSIONS In this small cohort of patients with metastatic neuroblastoma, GTR at the time of diagnosis offered a survival benefit. Further prospective studies are warranted before this approach can be applied to all patients with metastatic neuroblastoma.

Abstract
The aim of the present study was to evaluate the effectiveness of two consecutive nonrandomised treatment programs applied between 1989 and 1999 at the Istituto Nazionale Tumori of Milan in an unselected cohort of 59 children over the age of one with stage 4 neuroblastoma. Both treatment programs consisted of two phases, the induction of the remission phase and the consolidation phase. The induction of the remission phase consisted of intensive chemotherapy, and remained the same throughout the study period. The consolidation phase consisted of sequential hemi-body irradiation (HBI) (10 Gy per session, 6 weeks apart) in the first period (1988–June 1994) and sequential high-dose cyclophosphamide, etoposide, mitoxantrone+L-PAM and autologous haemopoietic stem cell transplantation in the second (July 1994–1999). Intention-to-treat analysis revealed a significantly better outcome for patients treated with the second program, the 5-year event-free survival probability being 0.12 for program 1 and 0.31 for program 2 (P=0.03). This finding led us to conclude that sequential HBI is useless as consolidation treatment. The high-dose chemotherapy adopted in the second program enabled a proportion of patients to obtain long-term survival but, since the clinical results remain unsatisfactory, new treatment strategies are warranted.

Abstract
Neuroblastoma is the most common solid tumour in childhood. Modern management includes a biopsy to perform genetic studies. Based on clinical data and Myc-N amplification (MNA), patients are divided in three prognostic groups: the low-risk (Stage 1, 2, 4S without MNA) has an event-free survival (EFS) of > 90% with surgery alone; the intermediate-risk (Stage 3, > 1 year of age, without MNA and Stage 3 and 4 infants without MNA) has an EFS of approximately 80% with mild chemotherapy and surgery; the high-risk group includes Stage 4, > 1 year of age and any stage and age with MNA. These patients are treated with chemotherapy, surgery, megatherapy, irradiation and 13-cis-retinoic acid. With this complex therapy, a 5-year EFS of 30-50% can be obtained.

Abstract
The authors retrospectively analyzed the long-term outcome of 67 patients over 1 year of age at diagnosis with high-risk neuroblastoma (stage 4 or stage 3 with N-myc amplification) who were treated with megatherapy and stem cell rescue from 1984 to 1998. Median age at transplant was 4 years (range 1.6-15 years). The source of cells was peripheral stem cells in 29 and bone marrow in 38 patients. In 12 patients, an in vitro purging of bone marrow harvest was performed. Most patients were conditioned with melphalan, BCNU, and VM-26. After transplant 19 patients received complementary treatment with IL-2 (16) or 13-cis-retinoic acid (3). Six patients (8%) died from transplant-related toxicity and 39 from disease progression. Three patients were alive with active disease at the time of analysis. Nineteen patients are alive and disease-free at a median follow-up of 104 months. Five-year event-free survival is 0.30. Survival of patients who received a purged graft was not significantly better than the rest. Post-transplant complementary treatment significantly improved overall and event-free survival (p = .01 and p = .04, respectively).

Abstract
Significant differences exist between the European and North American treatment protocols for Wilms' tumor and neuroblastoma. There are variations in biopsy technique, timing and extent of initial surgery, chemotherapy protocols and dosage routines, as well as the type of salvage therapy. With the consolidation of the two major North American study groups into a single entity (Children's Oncology Group), the European and North American study groups represent the only remaining large-scale venues for treatment comparison. It is important to study and understand the variation in treatment protocols in order to maintain an open forum of scientific investigation that will lead to improving the care and outcome of children with cancer. It is anticipated that the unification of the North American groups will lead to greater interest and scientific cooperation with the European study group. This paper will serve as a forum for such a discussion at a local level.

Abstract
BACKGROUND/PURPOSE Gross total resection of the primary tumor in treatment of high-risk neuroblastoma remains controversial. Furthermore, there are few reports of the effect of primary tumor resection on local control as opposed to overall survival. The authors reviewed their institutional experience to assess the effect of primary tumor resection on local control and overall survival. METHODS A total of 141 patients were treated on protocol between November 1, 1979 and June 25, 2002 and are the subject of this report. Gross total resection was assessed by review of operative notes, postoperative computerized axial tomograms, and postoperative meta-iodobenzyl guanidine (MIBG)1 scans when available. RESULTS The median age was 3.3 years, and all patients were International Neuroblastoma Staging System (INSS) stage 4 with 79% having metastases to cortical bone. The primary site was the adrenal gland in 74%, the central abdominal compartment in 13%, the posterior mediastinum in 7%, and other sites in 6%. Gross total resection was accomplished in 103 (73%) but was more than 90% for the last 3 protocols. Five kidneys were lost overall. The probability of local progression was 50% in unresected patients compared with 10% in patients undergoing gross total resection (P <.01). Overall survival rate in resected patients was 50% compared with 11% in unresected patients (P <.01). CONCLUSIONS Our data indicate that local control and overall survival rate are correlated with gross total resection of the primary tumor in high-risk neuroblastoma. Gross total resection should be part of the management of stage 4 neuroblastoma in patients greater than 1 year of age.

Abstract
The clinical use of N-myc amplification in neuroblastoma management has served as a paradigm for "bench to bedside" medicine. It is hoped that the quest for molecular markers such as neurotrophin, TrkA, and TrkB will continue to advance the understanding of neuroblastoma. In addition, animal models of neuroblastoma (N-myc transgenic mice, and neuroblastoma xenografts) have been established to assess the efficacy of novel treatments. These advances are likely to improve clinical practice in the future.

Abstract
During the last two decades new diagnostic and therapeutic tools have been utilized to improve the poor survival chances of children with stage 4 neuroblastoma. This study reviews the risk profiles and the long-term outcome of patients from five consecutive German neuroblastoma trials. A total of 96% of all German patients registered at the German childhood cancer registry with neuroblastoma stage 4 over 1 year of age at diagnosis entered one of the trials during 1979-2001. Eight hundred and twenty-eight consecutive children were analyzed retrospectively. In spite of having significantly improved diagnostic tools like bone marrow superstaging and mIBG scintigraphy the stage 4 incidence did not increase after reaching completeness of the registry (5.4 cases/100,000 children at 1-14 years of age; P=0.52). The distribution of the primary tumors and of metastases was constant over the periods. The amount of bone marrow infiltration did not change with time. The risk factors lactate dehydrogenase, ferritin and MYCN, and the clinical risk groups 4A, 4B, 4C also remained constant over the trials with a few exceptions for NB97. The 5-year event free survival increased from 0.01+/-0.01 (NB79) to 0.14+/-0.03 (NB85), 0.16+/-0.04 (NB82), 0.27+/-0.02 (NB90), and 0.33+/-0.04 (NB97). The overall survival rates improved similarly from 0.04 (NB79) to 0.44 (NB97). In conclusion, the improved survival was associated with better treatment and not caused by lower risk profiles in stage 4 neuroblastoma patients.

Abstract
Stage 4S neuroblastoma is a disease associated with spontaneous regression and good survival. We present a patient whose evolution has shown the variety and complexity of this disease in infants. Biologic factors, such as ploidy, MYCN copy number, loss of 1p36, and other chromosomal gains and losses were determined. A complex pattern of genetic abnormalities, such as near-diploidy, MYCN gain (2-4 copies per haploid genome) and imbalance/deletion of 1p36 was seen in the diagnostic sample. An extensive disseminated disease after a latent period of 26 months was associated with a special genetic evolution, such a tetraploidy, MYCN amplification (2:100-500 copies), 1p36 deletion, and gain of 17q. Our results provide evidence that either the primary tumor was heterogeneous in terms of gene amplification or that amplification was acquired later on as a transition from MYCN gain. We suggest that near-di-/tetraploid 4S tumors with MYCN gain and/or deletion 1p could be progressing 4S tumors.

Abstract
BACKGROUND/PURPOSE The importance of primary tumor resection in stage IV neuroblastoma is controversial. The authors analyzed prospectively the role of surgery in a multicentric series of stage IV neuroblastoma patients. METHODS Patients were studied according to the International Neuroblastoma Staging System (INSS) recommendations. Age, sex, location of the tumor, type of metastases, time of resection (initial or delayed), extension of resection, surgical complications, pathology, N-myc and Shimada classification results, relapses, and outcome were studied. After diagnosis, children received induction chemotherapy followed by delayed surgery and autologous stem cell transplantation or maintenance chemotherapy. Resection was classified as complete (C), greater than 90% (P1), greater than 50% (P2), less than 50% (P3), and biopsy (B). RESULTS Ninety-eight stage IV children were admitted in the study from June 1992 to July 1999. Seventy-six were older than one year, and in 78 the primary tumor was abdominal. Bone was the most common metastatic site followed by bone marrow. Initial biopsy was performed in 74 patients, and resection in 6, with one complication in each group. N-myc was amplified in 20 of 80 tumors, and Shimada was unfavorable in 45 of 67. Delayed surgery was performed in 70 cases, achieving gross total resection in 55 (79%); there were minor complications in 10%. Mean survival rate time was 50 months. Event-free survival rate (EFS) at 5 years for the entire series is 0.32, but 0.0 for children having biopsy only, 0.25 for less than 50% resection, 0.31 for 50% to 90% resection, 0.44 for greater than 90% resection, and 0.33 for complete resection. Differences were statistically significant only when compared with the biopsied group. EFS rate for infants was 0.56, but, again, there was no difference in relation to the type of resection. There were 46 relapses, 12 of them local, 7 of 20 N-myc-amplified tumors, and 4 of 60 not amplified (P <.005). CONCLUSIONS Biopsies of stage IV neuroblastoma allow safe assessment of N-myc and other biological factors on tumor tissue. Delayed surgery after chemotherapy is performed with a low rate of complications, achieving a good local control of disease. N-myc-amplified tumors have higher local relapse rates than nonamplified and therefore would need more intensive local treatment. The final outcome in these patients is determined more by metastatic relapses than by the degree of resection.
