Abstract
Triple-negative breast cancer (TNBC) is a heterogeneous disease characterized by lack of hormone receptor expression and is known for high rates of recurrence, distant metastases, and poor clinical outcomes. TNBC cells lack targetable receptors; hence, there is an urgent need for targetable markers for the disease. Breast cancer stem-like cells (BCSCs) are a fraction of cells in primary tumors that are associated with tumorigenesis, metastasis, and resistance to chemotherapy. Targeting BCSCs is thus an effective strategy for preventing cancer metastatic spread and sensitizing tumors to chemotherapy. The CD44hi CD24lo phenotype is a well-established phenotype for identification of BCSCs, but CD44 and CD24 are not targetable markers owing to their expression in normal tissues. The ganglioside GD2 has been shown to be upregulated in primary TNBC tumors compared with normal breast tissue and has been shown to identify BCSCs. In this review, we discuss GD2 as a BCSC- and tumor-specific marker in TNBC; epithelial-to-mesenchymal transition and the signaling pathways that are upstream and downstream of GD2 and the role of these pathways in tumorigenesis and metastasis in TNBC; direct and indirect approaches for targeting GD2; and ongoing clinical trials and treatments directed against GD2 as well as future directions for these strategies.

Abstract
Neuroblastoma (NB) is a neuroectodermal embryonic cancer that originates from primordial neural crest cells, and amongst pediatric cancers with high mortality rates. NB is categorized into high-, intermediate-, and low-risk cases. A significant proportion of high-risk patients who achieve remission have a minimal residual disease (MRD) that causes relapse. Whilst there exists a myriad of advanced treatment options for NB, it is still characterized by a high relapse rate, resulting in a reduced chance of survival. Disialoganglioside (GD2) is a lipo-ganglioside containing a fatty acid derivative of sphingosine that is coupled to a monosaccharide and a sialic acid. Amongst pediatric solid tumors, NB tumor cells are known to express GD2; hence, it represents a unique antigen for subclinical NB MRD detection and analysis with implications in determining a response for treatment. This article discusses NB MRD expression and analytical assays for GD2 detection and quantification as well as computational approaches for GD2 characterization based on high-throughput image processing and genomic data analysis.

Abstract
Neuroblastoma is a common extracranial solid tumor of neural crest (NC) origin that accounts for up to 15% of all pediatric cancer deaths. The disease arises from a transient population of NC cells that undergo an epithelial-mesenchymal transition (EMT) and generate diverse cell-types and tissues. Patients with neuroblastoma are characterized by their extreme heterogeneity ranging from spontaneous regression to malignant progression. More than half of newly diagnosed patients present highly metastatic tumors and are stratified into a high-risk group with dismal outcome. As many as 20% of high-risk patients have residual disease that is refractory or progressive during induction chemotherapy. Although a majority of high-risk patients achieve remission, larger part of those patients has minimal residual disease (MRD) that causes relapse even after additional consolidation therapy. MRD is composed of drug-resistant tumor cells and dynamically presented as cancer stem cells (CSCs) in residual tumors, circulating tumor cells (CTCs) in peripheral blood (PB), and disseminated tumor cells (DTCs) in bone marrow (BM) and other metastatic sites. EMT appears to be a key mechanism for cancer cells to acquire MRD phenotypes and malignant aggressiveness. Due to the restricted availability of residual tumors, PB and BM have been used to isolate and analyze CTCs and DTCs to evaluate MRD in cancer patients. In addition, recent technical advances make it possible to use circulating tumor DNA (ctDNA) shed from tumor cells into PB for MRD evaluation. Because MRD can be detected by tumor-specific antigens, genetic or epigenetic changes, and mRNAs, numerous assays using different methods and samples have been reported to detect MRD in cancer patients. In contrast to the tumor-specific gene-rearrangement-positive acute lymphoblastic leukemia (ALL) and the oncogenic fusion-gene-positive chronic myelogenous leukemia (CML) and several solid tumors, the clinical significance of MRD remains to be established in neuroblastoma. Given the extreme heterogeneity of neuroblastoma, dynamics of MRD in neuroblastoma patients will hold a key to the clinical validation. In this review, we summarize the biology and detection methods of cancer MRD in general and evaluate the available assays and clinical significance of neuroblastoma MRD to clarify its dynamics in neuroblastoma patients.

Abstract
BACKGROUND Loss of disialoganglioside 2 (GD2) expression in neuroblastoma (NB) bone marrow cells has been reported in rare cases. This study investigated prospectively the frequency and the patterns of visible GD2 loss at diagnosis, during treatment, and at recurrence. METHODS Bone marrow aspirates of patients with new or recurrent stage 4 and 4S NB diagnosed between January 1, 2002 and August 31, 2013 were investigated in parallel by cytology and GD2 immunocytology. Complete negative immunostaining was defined if staining was absent in all and partial if absent in a portion and/or in case of atypical faint staining. RESULTS Of 1,261 investigated trial patients of all stages, 474 had unequivocal cytological bone marrow infiltration at initial diagnosis. Thirty-seven patients had tumor cells with complete or partial negative GD2 staining at initial diagnosis, nine during chemotherapy, and 11 at recurrence (altogether 12.0%). The percentage of GD2 negativity in stages 4 and 4S were similar (13% and 9%, respectively). Complete negativity was seen in 14 and partial in 43 cases. Twenty-one cases changed from positive to negative (15 to partial and six to complete) and three cases from negative to positive staining (two to partial and one to complete). The GD2 negative and positive groups were not different regarding tumor sites, molecular characteristics, histology, and tumor markers. Children with stage 4 and GD2 negativity tended to be older at diagnosis (42 vs. 32 months, P = 0.056). Event-free survival and overall survival comparing negative versus positive staining did not show any differences. CONCLUSIONS Complete or partial lack of GD2 staining on NB cells in bone marrow is more frequent than currently recognized.

Abstract
Neuroblastoma is the most common solid tumor in children with an estimated 5-year progression free survival of 20–40% in stage 4 disease. Neuroblastoma actively avoids recognition by natural killer (NK) cells and cytotoxic T lymphocytes (CTLs). Although immunotherapy has gained traction for neuroblastoma treatment, these immune escape mechanisms restrain clinical results. Therefore, we aimed to improve neuroblastoma immunogenicity to further the development of antigen-specific immunotherapy against neuroblastoma. We found that neuroblastoma cells significantly increase surface expression of MHC I upon exposure to active NK cells which thereby readily sensitize neuroblastoma cells for recognition by CTLs. We show that oncoprotein PRAME serves as an immunodominant antigen for neuroblastoma as NK-modulated neuroblastoma cells are recognized by PRAMESLLQHLIGL/A2-specific CTL clones. Furthermore, NK cells induce MHC I upregulation in neuroblastoma through contact-dependent secretion of IFNγ. Our results demonstrate remarkable plasticity in the peptide/MHC I surface expression of neuroblastoma cells, which is reversed when neuroblastoma cells experience innate immune attack by sensitized NK cells. These findings support the exploration of NK cells as adjuvant therapy to enforce neuroblastoma-specific CTL responses.

Abstract
Neuroblastoma (NB), accounting for 10% of childhood cancers, exhibits aberrant cell-surface glycosylation patterns. There is evidence that changes in glycolipids and protein glycosylation pathways are associated to NB biological behavior. Polysialic acid (PSA) interferes with cellular adhesion, and correlates with NB progression and poor prognosis, as well as the expression of sialyltransferase STX, the key enzyme responsible for PSA synthesis. Galectin-1 and gangliosides, overexpressed and actively shedded by tumor cells, can modulate normal cells present in the tumor microenvironment, favoring angiogenesis and immunological escape. Different glycosyltransferases are emerging as tumor markers and potential molecular targets. Immunotherapy targeting disialoganglioside GD2 rises as an important treatment option. One anti-GD2 antibody (ch14.18), combined with IL-2 and GM-CSF, significantly improves survival for high-risk NB patients. This review summarizes our current knowledge on NB glycobiology, highlighting the molecular basis by which carbohydrates and protein–carbohydrate interactions impact on biological behavior and patient clinical outcome.

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
PURPOSE PCR-based detection of minimal residual disease (MRD) in neuroblastoma (NB) is presently based on NB-specific transcripts. However, the expression of these targets varies between patients and upon treatment, and only PHOX2B is truly specific. RASSF1a is methylated (RASSF1a(M)) in NB, and we investigated whether it can serve as a specific and stable DNA MRD marker. PATIENTS AND METHODS The RASSF1a(M)-specific quantitative real-time PCR was tested on control bone marrow (BM; n = 50), on 71 NB tumors, and on 159 clinical BM samples at diagnosis and at follow-up of 77 patients. Results were compared with a panel of RNA markers and correlated with prognosis. RESULTS RASSF1a(M) was present in all stage 4 and 4s tumors (n = 50) and in 86% stages 1 to 3 tumors (n = 21). The level of methylation in stage 4 NB was correlated with overall survival (P = 0.02). RASSF1a(M)-PCR was highly specific (only 1 amplification in 50 control samples tested in triplicate) and had a similar sensitivity as the RNA-based PCRs, as shown on clinical samples. Moreover, RASSF1a(M) enabled accurate quantification without need for the original tumor. CONCLUSIONS RASSF1a(M) is a novel, highly specific DNA marker for MRD detection in NB, equal to PHOX2B in specificity and sensitivity, and better suitable for MRD quantification. We propose to include RASSF1a(M) in further prospective MRD studies in NB alongside RNA MRD markers. In addition, this assay might also be applicable for detection of circulating tumor cells in patients with other cancers withRASSF1a(M) such as breast or lung cancer.

Abstract
BACKGROUND Graft contamination has been blamed for causing relapse in children with high-risk neuroblastoma (HRNB) after autologous hematopoietic stem cell transplantation (HSCT). PROCEDURE We report the long-term results of hematopoietic reconstitution, post-transplant complications, and clinical outcome of 44 children with HRNB treated with busulfan/melphalan high-dose chemotherapy followed by transplantation of purged CD34+ immunoselected autologous peripheral HSCT. Minimal residual disease (MRD) of grafts was evaluated by anti-GD2 immunofluorescence or tyrosine hydroxylase reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS Contaminating neuroblasts were found in 19/38 grafts (50%) before CD34+ positive selection, and none after (technique sensitivity of one cell in 10(5)). A median of 6.5 × 10(6) CD34+ cells/kg (range 0.8-23.7) were transplanted with only 2% of TRM. Neutrophils and platelet recovery occurred within a median of 12 days (range 9-47) and 44 days (range 12-259), respectively, without any secondary graft failure. Twenty-three percents of patients experienced a sepsis (10/44) and 14% a pyelonephritis (6/44). Recurrence of varicella zoster virus occurred in 21% of patients (9/44). Negative RT-PCR MRD within the leukapheresis product and cis-retinoic acid therapy were significantly and independently associated to a better survival (P < 0.05). Overall and event-free survivals at 5 years post-transplant were at 59.3% and 48.3% respectively. CONCLUSIONS Besides high rates of manageable infections due to late immune recovery, transplantation with CD34+ immunoselected grafts in HRNB children was feasible and did not affect long-term hematopoiesis.

Abstract
Disseminating disease is a predictive and prognostic indicator of poor outcome in children with neuroblastoma. Its accurate and sensitive assessment can facilitate optimal treatment decisions. The International Neuroblastoma Risk Group (INRG) Task Force has defined standardised methods for the determination of minimal disease (MD) by immunocytology (IC) and quantitative reverse transcriptase-polymerase chain reaction (QRT-PCR) using disialoganglioside G(D2) and tyrosine hydroxylase mRNA respectively. The INRG standard operating procedures (SOPs) define methods for collecting, processing and evaluating bone marrow (BM), peripheral blood (PB) and peripheral blood stem cell harvest by IC and QRT-PCR. Sampling PB and BM is recommended at diagnosis, before and after myeloablative therapy and at the end of treatment. Peripheral blood stem cell products should be analysed at the time of harvest. Performing MD detection according to INRG SOPs will enable laboratories throughout the world to compare their results and thus facilitate quality-controlled multi-centre prospective trials to assess the clinical significance of MD and minimal residual disease in heterogeneous patient groups.

Abstract
Several transcripts have been claimed to be clinically valuable for detecting minimal disease in neuroblastoma, but they have not been prospectively compared in a standardized manner. Tyrosine hydroxylase (TH), dopa decarboxylase (DDC) and GD2 synthase (GD2S) mRNAs were analyzed in 554 blood (PB) and bone marrow (BM) samples from 58 children with neuroblastoma. Samples from 44 children with other diseases served as controls. High transcript concentrations of TH, GD2S or DDC in PB or BM at diagnosis were associated with poor prognosis. TH in BM above median indicated worse outcome for a homogenous cohort with high-risk neuroblastoma (survival probability 91% for TH below median versus 33% for TH above median, p = 0.009). The number of children with localized neuroblastoma with increased results in PB did not differ between the three transcripts. In these children, all without morphologically detectable neuroblastoma in BM, the number of patients with elevated GD2S in BM at diagnosis was significantly higher than for the other transcripts (10/16 elevated, p = 0.012). GD2S was elevated in PB from 10/28 controls without neuroblastoma compared to 1/28 for TH and DDC (p < 0.001). In BM from these children GD2S was significantly elevated. We conclude that high expression of TH and DDC both in PB and BM corresponds to metastatic neuroblastoma at diagnosis, residual disease, and poor outcome. Children with high-risk neuroblastoma and low levels of TH in BM at diagnosis may be cured by current therapy. GD2S is less specific than TH and DDC mRNA for neuroblastoma detection in PB and BM.

Abstract
Neuroblastoma is a heterogeneous pediatric tumor thought to arise from the embryonic neural crest. Identification of the cell responsible for propagating neuroblastomas is essential to understanding this often recurrent, rapidly progressing disease. We have isolated and characterized putative tumor-initiating cells from 16 tumors and bone marrow metastases from patients in all neuroblastoma risk groups. Dissociated cells from tumors or bone marrow grew as spheres in conditions used to culture neural crest stem cells, were capable of self-renewal, and exhibited chromosomal aberrations typical of neuroblastoma. Primary spheres from all tumor risk groups differentiated under neurogenic conditions to form neurons. Tumor spheres from low-risk tumors frequently formed large neuronal networks, whereas those from high-risk tumors rarely did. As few as 10 passaged tumor sphere cells from aggressive neuroblastoma injected orthotopically into severe combined immunodeficient/Beige mice formed large neuroblastoma tumors that metastasized to liver, spleen, contralateral adrenal and kidney, and lung. Furthermore, highly tumorigenic tumor spheres were isolated from the bone marrow of patients in clinical remission, suggesting that this population of cells may predict clinical behavior and serve as a biomarker for minimal residual disease in high-risk patients. Our data indicate that high-risk neuroblastoma contains a cell with cancer stem cell properties that is enriched in tumor-initiating capacity. These cells may serve as a model system to identify the molecular determinants of neuroblastoma and to develop new therapeutic strategies for this tumor.

Abstract
Abstract
Background: Reliable detection of neuroblastoma cells in bone marrow (BM) is critical because BM involvement influences staging, risk assessment, and evaluation of therapeutic response in neuroblastoma patients. Standard cytomorphologic examination of BM aspirates is sensitive enough to detect single tumor cells. Consequently, more sensitive and specific detection methods are indispensable.
Methods: We used real-time quantitative reverse transcription-PCR (QPCR) of the tyrosine hydroxylase (TH), GD2 synthetase (GALGT), and embryonic lethal, abnormal vision, Drosophila-like 4 (ELAVL4) genes to detect disseminated neuroblastoma cells. We assessed assay sensitivity by addition experiments and then analyzed 97 neuroblastic tumor, BM, peripheral blood (PB), or peripheral blood stem cell (PBSC) samples from 30 patients. The QPCR results were compared with those of a standardized immunocytochemical assay.
Results: The molecular markers were highly expressed in all evaluated tumor samples. In addition, 32%, 11%, and 38% of all BM, PB, and PBSC samples scored positive for TH, GALGT, or ELAVL4, respectively. The TH and ELAVL4 assays could detect 1 neuroblastoma cell in 106 mononuclear cells. By contrast, the GALGT QPCR assay could detect 1 neuroblastoma cell in 104 mononuclear cells. We assessed the potential prognostic value of TH, GALGT, and ELAVL4 QPCR by analyzing subsequent samples from 3 patients with stage 4 disease. Preliminary results indicated that persistence of high ELAVL4 expression has prognostic value.
Conclusions: ELAVL4 QPCR can be used to detect residual neuroblastoma cells in clinical samples. However, combination of several molecular markers and screening techniques should be considered to ensure reliable detection of rare neuroblastoma cells.

Abstract
BACKGROUND In patients with neuroblastoma morphological assessment of BM for residual NB cells is not precise, particularly when the number of tumor cells is small. PROCEDURE To develop a sensitive and rapid method of detecting NB cells in BM, we assessed the efficiency of flow cytometry (FCM) using markers CD9, CD56, and CD45. The percent of CD9+/CD56+/CD45- (NB phenotype) cells was determined by FCM in 41 samples (16 patients) at various time points. For confirmation fluorescence in situ hybridization (FISH) for 17q gain was performed. RESULTS Nineteen of the 22 (86%) samples that were negative by morphology were positive by FCM (>0.006% CD9+/CD56+/CD45- cells). The longest time to complete the FCM study was 3 hr. In six FISH experiments the sorted CD9+/CD56+/CD45- population had a higher percentage of cells with 17q gain (11.5-95%) compared to a CD56-/CD45+ internal control population (2-8%). CONCLUSIONS Our preliminary results suggest that FCM determination of the percent of CD9+/CD56+/CD45- cells is an effective method of rapidly detecting NB cells in BM.

Abstract
While cyto- and histological screening of bone marrow samples are still accepted as the gold standard for initial staging of neuroblastoma patients, these applications are insufficient during or after therapy because it is not always possible to detect tumour cell infiltration below the level of 1% by morphology alone. For monitoring of minimal residual disease, techniques offering a considerably higher sensitivity have been developed. Immunocytology, RT-PCR and flow cytometry are most frequently used, but differ with regard to targets (single cells, RNA transcripts), measured parameters (tumour cell number, antigen expression, cytomorphology, cytogenetic aberrations, level/number of RNA transcripts), specificity (uni-/multi-parameter analysis) and sensitivity (number of investigated cells). The pros and cons of these methods are reviewed. Precise quantification of residual tumour cells in bone marrow and blood may show a future impact on risk grouping and therapeutic strategies for patients with disseminated disease, but the potential clinical application of these techniques has to be preceded by thorough standardisation and validation in multi-centre studies.

Abstract
Immunocytological bone marrow assessment for contamination with neuroblastoma cells is based on their characteristic GD2 surface staining. Neuroblastoma without GD2 expression have been rarely and only after antibody therapy reported. Conventional cytology was performed using Pappenheim staining. For immunocytology, the APAAP method was utilized with the 14G2a anti-GD2 mouse monoclonal antibody. 7 x 10(5) cells on cytospin preparations were investigated. In 2003, 288 bone marrow samples from 191 neuroblastoma patients were investigated by cytology and immunocytology. Three cases demonstrated GD2 negativity on cytologically unambiguous neuroblastoma cells. Two female cases (94 and 37 months of age) with stage 4 neuroblastoma had GD2 expressing neuroblastoma cells in bone marrow at diagnosis. At 2nd relapse 25 and 23 months after diagnosis and 8 months and 12 months after anti-GD2 antibody treatment (ch14.18), the bone marrow infiltrating neuroblastoma cells lacked GD2 staining. The third patient, a 63-month-old girl with bone marrow replacement by neuroblastoma cells showed at diagnosis a mixture of GD2-unstained tumor clumps and very weakly stained neuroblastoma cells. Neuroblastoma cells may lack GD2 expression at diagnosis and at recurrence. This observation has diagnostic and therapeutic implications.

Abstract
Standard cytomorphological examination of bone marrow (BM) aspirates does not appear to be sensitive enough to detect single neuroblastoma cells. The SIOPEN Neuroblastoma Bone Marrow Committee developed a sensitive and reproducible anti-GD2 immunocytochemical assay and introduced morphological and immunocytological criteria for the interpretation of results. Fixed cytospins were incubated with a commercially available anti-GD2 monoclonal antibody and an APAAP kit. Cells fulfilling all morphological and immunocytological criteria were called criteria-positive cells (CPCs). Not convincingly interpretable cells fulfilled some, but not all, criteria, and negative cells displayed only exclusion criteria. The genetic profile of doubtful cells was checked by fluorescence in situ hybridization. Ideally, 3 x 10(6) cells were analyzed to reach a 95% probability of detecting one tumor cell in 1 x 10(6) mononuclear cells. Four quality control rounds were organized to validate the method. A total of 111 quality control samples were analyzed. Two main improvements were achieved: in discordant cases, the range between the lowest and highest reported result was reduced by half, and discordant results were only found in samples with less than 10 CPCs per 1 x 10(6). This article describes the first internationally standardized protocol to detect and quantify rare neuroblastoma cells by immunocytochemistry. This method is an indispensable tool for multicenter studies evaluating the clinical significance of minimal residual disease in neuroblastoma.

Abstract
Neuroblastoma (NB) is a pediatric extracranial tumor characterized by downregulation of human leukocyte antigen class I and defects of the antigen processing machinery, two features that make it an appropriate target for natural killer (NK)-mediated lysis. NKG2D is an activating immunoreceptor expressed by cytotoxic T lymphocytes and NK cells. The ligands for NKG2D are the major histocompatibility complex class I-related chain (MIC)A and MICB glycoproteins, and the UL-16-binding proteins (ULBPs). Here, the expression of NKG2D ligands was investigated in human primary NB tumors and cell lines because scanty information is available on this issue. MICA, MICB, and ULBP transcripts were found in most tumors and cell lines. MICA protein was detected in some NB cell lines but not in primary tumors. A soluble form of MICA (sMICA) was identified in most patient sera and in some cell line supernatants. sMICA downregulated surface NKG2D in normal peripheral blood CD8(+) cells and decreased NK-mediated killing of MICA(+) NB cells. MICB was detected exclusively in the cytosol of primary tumors and cell lines. Approximately 50% of primary tumors expressed ULBP-2, but not ULBP-1 or -3. ULBP-3 was expressed in 5 of 9 cell lines, ULBP-2 in 2 of 9, whereas ULBP-1 was never detected. These studies delineate novel potential pathways of tumor escape and immunodeficiency in NB.

Abstract
BACKGROUND Because the cytomorphologic examination of bone marrow (BM) aspirates appears not sensitive enough to detect residual neuroblastoma cells, two four-color flow cytometric assays using different combinations of CD9, CD81, CD56, CD45, and anti-GD2 were evaluated. METHODS The sensitivity of the flow cytometric assays was assessed by spiking experiments in normal peripheral blood samples. Twenty-eight BM samples, 12 biopsies, and 3 peripheral blood stem cell (PBSC) preparations from 22 patients with neuroblastoma were analyzed. The results were compared with those of an anti-GD2 immunocytochemical reference assay. RESULTS Flow cytometric and immunocytochemical analyses showed residual neuroblastoma cells in four BM samples. One PBSC preparation and 20 BM samples were negative for both assays. Four BM and two PBSC samples scored positive for the immunocytochemical assay but were negative for the flow cytometric tests. This was due to the limited number of cells that were flow cytometrically analyzed. A strong correlation between the flow cytometric and immunocytochemical tests was found (chi2 = 6.4, P = 0.011). CONCLUSIONS When an equal amount of cells is analyzed, the sensitivity of the flow cytometric assays is to be about 10 times lower than that of the immunocytochemical test. However, the flow cytometric assays can be used to screen for residual cells in clinical samples with a sensitivity of one neuroblastoma cell in 10(4) to 10(5) normal mononuclear cells. Flow cytometry is simple, quick, and cost effective compared with immunocytochemistry. In addition, the flow cytometric assays can be used to screen for residual neuroblastoma cells in case of a GD2-negative primary tumor. Therefore we recommend flow cytometry for the detection of residual neuroblastoma cells.

Abstract
PURPOSE Detection of metastatic tumor cells in bone marrow (BM) and peripheral blood (PB) of children with neuroblastoma is crucial for prognosis and planning of therapy. Aims of this large descriptive repeated survey were to evaluate the diagnostic accuracy of different techniques in diagnostic samples obtained at several disease course time points and to correlate positive results with patient clinical features and outcome. EXPERIMENTAL DESIGN BM aspirates, trephine biopsies, PB, and peripheral blood stem cell (PBSC) samples from Italian children with neuroblastoma were analyzed by morphological and histologic techniques, as well as by immunocytochemistry (IC) for disialoganglioside GD(2) and reverse transcription-PCRs (RT-PCRs) for tyrosine hydroxylase (TH) and pgp9.5 genes. The diagnostic odd ratio (DOR) was used to measure the accuracy of the different techniques. RESULTS A total of 2,247 evaluations were done on 561 BM, 265 PB, and 69 PBSC samples from 247 patients. IC showed the best accuracy. Whereas TH RT-PCR accuracy was satisfactory, that of pgp9.5 was very low. Positive results obtained by IC in BM and PB samples at diagnosis from stage 1, 2, and 3 patients correlated with unfavourable outcome. No correlation was found between positive results obtained by IC or TH RT-PCR in BM, PB, and PBSC samples from stage 4 patients and their outcome. CONCLUSIONS Because of its elevated diagnostic accuracy, IC may represent a useful adjunct to conventional morphological techniques, especially in view of its potential prognostic role in patients with localized disease. Longitudinal multicenter studies are warranted to definitely establish the clinical usefulness of TH RT-PCR.

Abstract
Despite advances in the treatment of neuroblastoma (NBL), recurrence and metastases continue to pose major problems in clinical management. The relation between micrometastases and the development of secondary disease is not fully understood. However, accurate methods to detect low numbers of tumour cells may allow the evaluation of their role in the disease process, and by implication the possible benefits of eliminating them. Although there is substantial evidence for the increased sensitivity of current molecular methods for the detection of NBL cells compared with more conventional cytology, the clinical relevance and usefulness of detecting this disease remain controversial. The primary goal of current translational research must be to evaluate the clinical relevance of micrometastatic disease detected by these methods in multicentre prospective clinical outcome studies. Only then can the clinical usefulness of these methods be defined so that they may be introduced into relevant clinical practice.

Abstract
The sensitive detection of bone marrow involvement is crucial for tumor staging at diagnosis and for monitoring of the therapeutic response in the patient's follow-up. In neuroblastoma, only conventional cytomorphological techniques are presently accepted for the detection of bone marrow involvement, yet since the therapeutic consequences of the bone marrow findings may be far-reaching, the need for highly reliable detection methods has become evident. For this purpose, we developed an automatic immunofluorescence plus FISH (AIPF) device which allows the exact quantification of disseminated tumor cells and the genetic verification in critical cases. In this study, the power of the immunofluorescence technique is compared with conventional cytomorphology. 198 samples from 23 neuroblastoma patients (stages 4 and 4s) at diagnosis and during follow-up were investigated. At diagnosis, 45.6% of the samples (26 of 57) which were positive by AIPF investigation were negative by cytomorphology. During follow-up, 74.2% (49 of 66) of AIPF-positive samples showed no cytological signs of tumor cell involvement. False negative morphological results were found in up to 10% of tumor cell content. A tumor cell infiltrate below 0.1% was virtually not detectable by conventional cytomorphology. Using the sensitive immunofluorescence technique, the analysis of only two instead of four puncture sites did not lead to false negative results. Thus, the immunofluorescence technique offers an excellent tool for reliable detection and quantification of disseminated tumor cells at diagnosis and during the course of the disease.

Abstract
The impact of monoclonal antibodies (mAbs) in the treatment of human tumors has greatly increased in recent years. mAb engineering has allowed reducing the immunogenicity of therapeutic antibodies as well as improving their biodistribution. Furthermore, engineered mAbs have been used to vehiculate toxins, drugs and other anti-neoplastic agents to the tumor site. In the case of neuroblastoma (NB), a pediatric malignancy originating from the neural crest, both murine and chimeric antibodies against the tumor associated antigen GD2 have been tested in clinical trials, either alone or in combination with cytokines. A novel promising approach to mAb engineering is the small immuno-protein (SIP) technique, whereby the variable regions of heavy and light chains of a mAb with a given specificity are connected to the dimerizing CH(3) domain of an immunoglobulin molecule. The current status of mAb therapy for NB is discussed together with our preliminary results on the generation of novel anti-GD2 molecules using the SIP technique.

Abstract
Tumour cells display low to absent expression of costimulatory molecules. Here, we have investigated the expression of costimulatory molecules (CD40, CD80, CD86, PD-1L, B7H2, OX40L and 4-1BBL) in human neuroblastoma (NB) cells, since virtually no information is available on this issue. Both established NB cell lines and primary tumours were tested by RT-PCR and flow cytometry. Neuroblastoma cell lines expressed the transcripts of all costimulatory molecule genes, but not the corresponding proteins. Culture of NB cell lines with human recombinant (r)IFN-gamma induced surface expression of CD40 in half of them. Primary NB cells showed CD40, CD80, CD86, OX40L, 4-1BBL, but not PD-1L and B7H2, mRNA expression. Surface CD40 was consistently detected on primary NB cells by flow cytometry. Interferon-gamma gene-transfected NB cells expressed constitutively surface CD40 and were induced into apoptosis by incubation with rCD40L through a caspase-8-dependent mechanism. CD40 may represent a novel therapeutic target in NB.

Abstract
Ten years ago, we made an incidental flow cytometric observation while immunophenotyping biopsy and marrow samples from children suspected to have leukemia/non-Hodgkin's lymphoma, but were subsequently diagnosed with neuroblastoma. The samples contained neoplastic CD45(-) cells that had an extremely bright CD56(+) (beyond the fourth decade on a four-decade scale) population distinguishable from CD45(+)CD56(usual density+) natural killer lymphocytes as well as other CD45(-)CD56(usual density+) nonhematopoietic tumors such as small cell carcinoma or melanoma. Following the "rare event" philosophy of selecting one negative and two positive antigens, we initially tried a "cocktail" of CD45(-)CD56(very bright+) neuron-specific enolase (NSE)(cytoplasmic+). We later modified the procedure to a more clinically applicable "lysed whole blood" CD45(-)CD56(very bright+) ganglioside GD2(+) cocktail to improve turnaround time (eliminating the cell permeabilization step for cytoplasmic NSE analysis), specificity, and sensitivity of the assay. A total of 123 marrow/tissue/fluid samples were analyzed by the various forms of the assay. Clearly interpretable samples had an 83% specificity and a 100% sensitivity. The three-color GD2 assay has successfully detected cells in marrow samples to a level of 0.002% (1 per 10(5) cells) using patient samples (not artificially "spiked" material). We added CD81 expression of the neuroblastoma cells as a fourth color and now use this rare event clinical test to help stage and monitor all patients with neuroblastoma.

Abstract
BACKGROUND Neuroblastomas (NBs) almost ubiquitously express the ganglioside GD2. GD2 synthesis is dependent on the key enzyme GD2 synthase. Thus, GD2 synthase transcript may prove to be a potential molecular marker of NB. METHODS Seventy-seven NB tumor tissues of all stages, 5 NB cell lines, and 26 normal bone marrows (BMs) and peripheral blood (PBL) samples, as well as 26 non-NB remission-BMs were analyzed for the expression of GD2 synthase by a highly sensitive reverse transcriptase-polymerase chain reaction (RT-PCR) and chemiluminescence detection. One hundred fifty-two NB BMs were tested and comparisons were made among three independent detection techniques, namely GD2 synthase RT-PCR, immunofluorescence (IF), and histology (HIST). RESULTS GD2 synthase transcript was present in 5 of 5 cell lines and in 77 of 77 tumors tested. Among 116 marrows that were positive by at least 1 of the 3 methods, 78% were detectable by GD2 synthase, 68% by IF, and 46% by HIST. Seventy-six percent of positive BMs that were obtained during treatment and follow-up had GD2 synthase expression, whereas only 29% were HIST positive. Correlation between RT-PCR and IF was high (P = 0.001), and positivity by 3 out of 3 methods was strongly correlated with poor survival (P < 0.01). Of note, marrows tested at the time of chemotherapy were positive by at least 2 out of 3 methods and were associated with adverse outcome (P = 0.01). Serial samples (n = 28) in 5 patients demonstrated close agreement between RT-PCR and patient disease status. CONCLUSIONS The current study found that molecular detection of GD2 synthase transcript in NB BMs may have potential value in detecting rare tumor cells.

Abstract
BACKGROUND Rare tumor cells circulating in the hematopoietic system can escape identification. On the other hand, the nature of these cells, positive for an immunologiCal tumor marker, cannot be determined without any genetic information. PROCEDURE To overcome these problems a novel computer assisted scanning system for automatic cell search, analysis, and sequential repositioning was developed. This system allows an exact quantitative analysis of rare tumor cells in the bone marrow and peripheral blood by sequential immunological and molecular cytogenetic characterization. RESULTS AND CONCLUSIONS In that virtually all tumor cells in a mixing experiment could be recovered unambiguously, we can conclude that the sensitivity of this approach is set by the number of cells available for analysis. Sequential FISH analyses of immunologically positive cells improve both the specificity and the sensitivity of the microscopic minimal residual disease detection.

Abstract
Accurate quantification of disseminated tumor cells in hematological samples is of fundamental importance in clinical oncology. However, even highly standardized protocols allow only a rough estimation of the total analyzed cell number, as sample processing may have adverse effects on the number of cells available for analysis. The fluorescence-based microscopic scanning system (MetaCyte) detects, counts, captures, and relocates immunolabeled tumor cells in hematopoietic samples. We report on a cell-counting approach that has been implemented into the scanning system to precisely quantify the number of cells per slide. The cell-counting function, which was designed to determine the number of all nucleated (DAPI-stained) cells on the slide, allows an accurate counting of the tumor cells and the total number of cells analyzed in the given microscopic sample. The reliability of the cell-counting approach was demonstrated by the analysis of DAPI-stained images with 18-1,363 nucleated cells. A good correlation (r(2) = 0.965) between the manually and automatically gained results was observed. The counting accuracy could even be optimized after implementing a correction factor. To prove or disprove an interslide variation, routine bone marrow cytospin preparations from neuroblastoma patients were immunostained for GD2/FITC and counterstained with DAPI. Automatic cell counting of cytospin preparations from the same patients showed significant differences in the total cell number (up to 67% cell loss during preparation, with a maximum interslide difference of 4.7 x 10(5) mononuclear cells). We conclude that determination of the tumor cell content in hematopoietic samples is only reliable when it is performed together with accurate cell counting.

Abstract
The aim of this study was to evaluate the specificity of a number of monoclonal antibodies (MAbs) used for immunological in vitro purging of stem cell grafts from neuroblastoma patients. The extent of cross-reactivity of 10 neuroblastoma-specific MAbs (NB-MAb) with CD34+ stem cells from 14 leukapheresis products was analyzed. The level of cross-reactivity was analyzed on a Coulter (Fullerton, CA) flow cytometer using biotinylated NB-MAbs. There was a marked difference in the reactivity of the ten NB-MAbs with CD34+ stem cells. The antibodies could be divided into three groups with increasing levels of cross reactivity. Four antibodies (126-4, 5.1 H11, UJ127.11, and 14.G2a) all reacted with median levels of less than 2% (range 0.0 to 5.4) of CD34+ stem cells (median of 14 patients). Another three antibodies reacted with a median of 3.1-4.1% of the stem cells (UJ13A, Ab390, and Ab459) but with a wide range (0.2 to 25.6). Finally, M340, HSAN 1.2, and antiThy-1 reacted with a median of 9-16% of the stem cells (range 0.6 to 51.5). We conclude that there is a significant variation in the proportion of CD34+ stem cells reacting with each of the ten neuroblastoma antibodies investigated in this study. Therefore, to avoid a significant loss of CD34+ cells from the stem cell product, we find it important to carefully consider which antibodies to use for immunomagnetic purging.

Abstract
PURPOSE To improve autologous leukapheresis strategies in high-risk neuroblastoma (NB) patients with extensive bone marrow involvement at diagnosis. PATIENTS AND METHODS Anti-G(D2) immunocytochemistry (sensitivity, 1 in 10(5) to 10(6) leukocytes) was used to evaluate blood and bone marrow disease at diagnosis and during the recovery phase of the first six chemotherapy cycles in 57 patients with stage 4 NB and bone marrow disease at diagnosis. A total of 42 leukapheresis samples from the same patients were evaluated with immunocytology, and in 24 of these patients, an anti-G(D2) immunomagnetic enrichment step was used to enhance tumor-cell detection. RESULTS Tumor cytoreduction was much faster in blood compared with bone marrow (3.2 logs after the first cycle and 2.1 logs after the first two cycles, respectively). Bone marrow disease was often detectable throughout induction, with a trend to plateau after the fourth cycle. By direct anti-G(D2) immunocytology, a positive leukapheresis sample was obtained in 7% of patients after either the fifth or sixth cycle; when NB cell immunomagnetic enrichment was applied, 25% of patients had a positive leukapheresis sample (sensitivity, 1 in 10(7) to 10(8) leukocytes). CONCLUSION Standard chemotherapy seems to deliver most of its in vivo purging effect within the first four cycles. In patients with overt marrow disease at diagnosis, postponing hematopoietic stem-cell collection beyond this point may not be justified. Tumor-cell clearance in blood seems to be quite rapid, and earlier collections via peripheral-blood leukapheresis might be feasible. Immunomagnetically enhanced NB cell detection can be highly sensitive and can indicate whether ex vivo purging should be considered.

Abstract
PURPOSE Intensive chemoradiotherapy followed by peripheral blood stem cell transplantation has been introduced to treat children with advanced neuroblastoma (NBL). Detection of NBL cells in peripheral blood (PB) is important to prevent reinfusion of NBL cells. Several immunologic methods have been proposed for detecting NBL cells in hematologic samples. The development of a sensitive and specific combination of monoclonal antibodies (MoAbs) for detecting small numbers of NBL cells in PB using flow cytometry remains an important challenge. METHODS Twenty-one clinical samples from NBL tissues or smears containing NBL cells were examined for reactivity against CD81, CD56, and CD9 using an immunocytochemical technique. The expressions of CD81, CD56, CD9, and antihuman disialoganglioside GD2 MoAb (GD2) in five NBL cell lines were assayed by flow cytometry. For the evaluation of sensitivity, five NBL cell lines were added to normal PB and the detection level of the combination of CD81/CD56/CD45 MoAbs was compared with that of CD9/CD56/CD45 MoAbs (reported previously). One hundred thirty-three normal PB samples were examined to determine the sensitivity and specificity of this method. RESULTS All NBL cell lines showed strong positivity with CD81 and CD56 MoAb. However, CD9 MoAb was weakly positive against the five NBL cell lines. GD2 MoAb reacted strongly with four NBL cell lines, although almost the entire cell population of the SK-N-SH NBL line failed to bind the GD2 MoAb. In vitro experiments using NBL cell lines demonstrated that tumor cells added to normal PB cells could be detected by flow cytometry using CD81/CD56/CD45 MoAbs even at a concentration of 0.005%. Through comparative studies, the combination of CD81/CD56/CD45 MoAbs was found to be more sensitive and specific than that of CD9/CD56/CD45 MoAbs for detecting small numbers of NBL cells using the above cell lines. CONCLUSIONS Triple-color flow cytometric analysis using CD81/CD56/CD45 MoAbs is useful for detecting NBL cells in PB. Further studies testing this approach using samples of PB with NBL contamination are needed to test this approach in patients.

Abstract
BACKGROUND Except at diagnosis and relapse, when gross disease is present, histologic evaluation is less sensitive than immunocytology (IC) of bone marrow for detecting metastatic neuroblastoma. We examined whether the chance of a positive IC from a single marrow site was comparable to an IC of pooled marrow from multiple sites. PROCEDURE We carried out 47 marrow examinations on 29 patients with high-risk neuroblastoma on therapy. Each examination consisted of histologic evaluation of four aspirates and two biopsies (six sites), IC of a 2.5-5-mL heparinized sample from a single site (the right posterior iliac crest; IC-RPIC), as well as IC of 8-10 mL of heparinized marrow pooled from bilateral anterior and bilateral posterior iliac crests (IC-pooled). IC was performed using a panel of monoclonal antibodies specific for ganglioside GD2. RESULTS The number of GD2-positive tumor cells detected by IC-pooled had a strong linear correlation with that by IC-RPIC (R = 0.91), although IC-pooled detected an average of 3.3 times more GD2-positive cells. Of 47 examinations, 15 tested positive by histology (6 sites), 20 by IC- pooled, and 17 by IC-RPIC. Among 29 patients, the level of agreement between IC-RPIC and IC-pooled was generally good (kappa statistic > or = 0.72), giving a false negative rate of < or = 30%. CONCLUSIONS Compared to conventional histologic examinations, immunocytology of a single marrow aspirate generally agrees with that of marrow pooled from six sites. However, the false negative rate may be too high in the setting of examination prior to bone marrow or stem cell harvest.

Abstract
High-sensitivity immunocytochemistry was used to evaluate the relative frequency of neuroblastoma cells in bone marrow and peripheral blood in patients with neuroblastoma (NB). A total of 51 concomitant paired blood and marrow samples (102 total) from 35 patients with NB (age 4 months-31 years; stage 29 stage IV, 4 stage III, 2 stage IVS; 14 at diagnosis, 18 in relapse, 12 during treatment, and 7 off-therapy) were analyzed. Cytospins containing up to 10(6) cells each were prepared using the mononuclear cell (MNC) fraction. For immunocytologic staining, a primary mouse monoclonal anti-GD2 antibody (3F8), a secondary antimouse biotinylated antibody, and a streptavidin-alkaline phosphatase complex were used. A minimum of two cytospins containing a mean of 1.4 x 10(6) total MNCs was analyzed in addition to a negative and a positive control. No circulating tumor cells were detected when the concomitant marrow samples were negative or had <10 positive cells per 106 MNC (23 of 51 samples). Of the 18 marrow samples positive at 10-10,000 cells per 106 MNC, 6 had detectable NB cells in the corresponding blood sample, whereas for marrow samples with >10,000 NB cells per 10(6) MNC (1%), the concomitant blood sample was positive for 9 of the 10. When both marrow and blood samples were positive (15 BM-PB pairs), NB cell frequency was significantly lower in blood, with a mean difference of 2.14 logs (median 2.22, range -0.16-4.8, standard error 0.38). In patients with NB, circulating tumor cell frequencies seem to be substantially lower than in concomitant marrow samples, with a mean difference of >2 logs.

Abstract
We have developed a multiassay system consisting of fluorescence microscopy, immunocytology and tumor colony assay to monitor the removal of tumor cells from bone marrow. This system was tested in preclinical purging experiments in which neuroblastoma cells were seeded into bovine marrow and purged by treatment with monoclonal antibodies and immunomagnetic beads. Eight experiments were performed on two different neuroblastoma cell lines seeded at 2% and/or 5% contamination. We consistently demonstrated greater than a 3 log removal with one cycle of antibody/bead treatment and greater than a 1 log further reduction by addition of a second cycle. We also demonstrated removal of all detectable tumor stem cells by this purging method. We feel that this system will prove valuable for monitoring ex vivo tumor removal in future clinical studies and should be considered for use in other purging trials.

Abstract
Although bone marrow examination is a common procedure in the evaluation of patients with cancer, its role and contribution have been questioned in recent years. This review deals with the clinical and biologic aspects of metastasis to the bone marrow. The discussion is focused on the common tumor types that involve marrow and the application of newer techniques for tumor detection in the marrow. Therapeutic and prognostic implications of bone marrow metastasis are significant in several clinical settings. The mechanisms by which tumor cells affect marrow function have not been completely defined.

Abstract
A review of stage IV-S neuroblastoma is provided. The possible uses of prognostic features to guide treatment options in this group of infants with neuroblastoma are suggested. The biologic basis for the spontaneous regression of widespread tumor involvement in some infants with stage IV-S neuroblastoma is discussed. The reasons that some infants with IV-S disease progress to a fatal outcome, while most undergo maturation or involution and eventual long term cure are suggested. The influence of such factors as age at diagnosis, clinical staging, and tumor biology on eventual outcome are covered. Biological variables and markers discussed include: genetic (cytogenetics (1p deletions), nuclear genomic content), molecular biologic (N-myc oncogene amplification, mdr-1, ras, and trk, gene expression), immunological (major histocompatibility antigen density, cellular and humoral immunity), and biochemical (creatine kinase isoenzyme profile, neuron specific enolase, ferritin, chromatograffin, lactic acid dehydrogenase and catecholamine levels).

Abstract
Murine monoclonal antibody (MAb) 3F8 was previously shown to react with disialoganglioside GD2, but not with GD3, GT1b, GD1b, GD1a, GM1, GM3 and GM4. However, when the base-treatment step was ommitted from the standard neuroblastoma ganglioside extraction procedure, immuno-thin-layer-chromatography (ITLC) using 3F8 and other anti-GD2 MAbs revealed a new ganglioside band, abbreviated as NG (Rf 0.342) besides GD2 (R 0.183). It migrated below GD3 (Rf 0.358) on high-performance (HP) TLC plate and its binding to 3F8 on ITLC could be inhibited by rat anti-3F8 idiotypic antibody Idio-2, while the binding of GD2 to MAb 3F8 was not affected. Immunochemical analysis showed that this new neuroblastoma ganglioside contained alkali-sensitive O-acetylated sialic-acid residues recognized by MAb DI.I. After base treatment, its subsequent identity on ITLC was confirmed to be GD2. Lactonization of GD2 yielded 2 major bands, with Rf values (0.401, 0.583) distinct from that of the new ganglioside band. In addition, MAb DI.I did not bind to any of these GD2 lactones. Of 15 anti-GD2 MAbs studied, 13 reacted strongly with the novel ganglioside NG. By ITLC, this NG was found in ganglioside extracts of fresh surgical tumor specimens (4/4 neuroblastomas, I/I schwannoma and I/I anaplastic astrocytoma), and nude mice/rat xenografts (2/2 neuroblastomas, 2/2 osteogenic sarcomas). These data provided the first evidence that O-acetylated GD2 is a naturally occurring ganglioside derivative in human tumors and that it could cross-react with most anti-GD2 antibodies.

Abstract
A prospective comparison between magnetic resonance imaging (MRI), 123I meta-iodobenzylguanidine (mIBG) scintigraphy and posterior iliac crest marrow aspiration and trephine biopsy in 30 assessments (19 patients) showed concordance between the three techniques in 16 assessments (53.3%). In 10 (33.3%), MRI and mIBG revealed abnormalities not detected by marrow biopsy. MRI was the only technique to demonstrate marrow abnormality in four assessments (13.3%). In addition, MRI revealed more sites of abnormality in 16 parallel assessments. We conclude that MRI shows promise as a non-invasive means of detecting bone marrow infiltration by neuroblastoma, but that further evaluation of the specificity of MRI in this setting is indicated.

Abstract
Autologous bone marrow transplantation (ABMT) allows delivery of intensive, marrow-ablative chemotherapy or chemoradiotherapy to children with high-risk solid tumors. Results from several studies of neuroblastoma suggest that outcome is improved by ABMT; however, relapses can occur months to years after complete clinical remission. Other high-risk tumors including peripheral neuroepithelioma, Ewing's sarcoma, rhabdomyosarcoma, Wilms' tumor, and brain tumors also appear to be responsive to intensive marrow-ablative therapy, although few studies have been reported. For tumors that can metastasize to marrow, a sensitive method is necessary for detecting tumor cell contamination. Immunocytologic analysis with monoclonal antibodies can identify one neuroblastoma cell per 10(5) normal marrow cells; this method also is applicable to other tumors with appropriate antibodies. Ex vivo removal (purging) of tumor cells decreases the probability of infusing tumorigenic cells with the ABMT. There is considerable experience in tumor detection and purging for neuroblastoma, but little has been done for other childhood solid tumors. Future investigations of ABMT will aim to further increase disease-free survival by intensifying induction and marrow-ablative regimens and by developing therapies to be given after ABMT that are directed at minimal residual disease. As pilot investigations mature, the efficacy of ABMT and conventional chemotherapy will be compared in multi-institution randomized studies.

Abstract
Combinations of aggressive therapy and radiotherapy directed at the primary tumor site as well as dose intensive chemotherapy against metastases can effectively induce complete remissions in patients with stage IV neuroblastomas. By virtue of its tumor specificity, the use of immunotherapy at the time when microscopic residual disease is present holds great promise in eradicating the tumors permanently. Monoclonal antibodies can accumulate selectively and at high concentrations in neuroblastomas. They have the potential of initiating complement activation and inflammation at the tumor site. Hematopoietic factors and cytokines can reinforce the body with tumoricidal leukocytes. Ex vivo activation of autologous white cells as well as arming by genetic manipulation can also produce tumor-seeking vehicles that may be therapeutically useful. As the knowledge of tumor and host immunobiology accumulates, the optimal combination of these approaches will become apparent.

Abstract
BACKGROUND Morphologic evaluation of bone marrow for neuroblastoma cells is a routine and important component of clinical staging. Specific immunostaining of malignant cells with monoclonal antibodies should be more sensitive, however, and may improve the detection of metastases and provide additional prognostic information. METHODS We looked for tumor cells in bone marrow from 197 patients with newly diagnosed neuroblastoma, using immunoperoxidase staining with monoclonal antibodies (immunocytologic analysis) and examination of smears and specimens obtained by trephine biopsy (conventional analysis). RESULTS Routine smears and trephine-biopsy specimens were positive for tumor cells in 46 percent of the patients, whereas 67 percent were positive on immunocytologic analysis (P less than 0.0001). Immunocytologic analysis detected bone marrow metastases in 34 percent of patients considered to have only localized or regional disease (Stage I, II, or III). It also identified tumor cells that were not detected by conventional analysis in patients with widespread disease (Stage IV or IVS). Tumor content, as determined by immunocytologic analysis, predicted clinical outcome in relation to the age of the patient at diagnosis. Patients with Stage II or III disease diagnosed after one year of age who did not have occult marrow metastases did well, whereas those with metastases did poorly (P = 0.006). Patients in whom Stage IV disease was diagnosed before they were one year of age did well if bone marrow metastases were few or absent, but had poor survival if the marrow contained more than 0.02 percent tumor cells (P = 0.03). CONCLUSIONS Immunocytologic analysis of bone marrow aspirates is more sensitive than conventional analysis in detecting tumor cells and provides prognostic information. The relations among marrow metastases, age at diagnosis, and clinical outcome illustrate the biologic heterogeneity of neuroblastoma.

Abstract
The use of labelled radiopharmaceuticals such as metaiodobenzylguanidine (m-IBG) enables neuroblastomas and other malignant cells from neural crests to be visualized. In vitro study of cellular incorporation into human neuroblastoma lines (SK-N-SH, SK-N-MC, LAN I) showed that only the SK-N-SH line retained iodine-125 m-IBG (125I-m-IBG) significantly. Fifty-five percent of the initial activity was retained after 1 hr incubation at a concentration of 10(-7) M of m-IBG (specific activity: 1,480 MBq/mg). Beyond this value, m-IBG uptake mechanisms were saturated. Study of release kinetics showed a rapid first phase (50% released after 4 hr) and a slower second phase (30% of the value retained at the equilibrium point was present after 48 hr), indicating the existence of a storage compartment. Autoradiography studies confirmed the intracytoplasmic localization of m-IBG and showed that a low percentage (3 to 5%) of SK-N-SH cells strongly retained m-IBG. Cytotoxicity tests showed that SK-N-SH cell growth was significantly reduced during the first days of culture, following 2 hr incubation with 1,500 KBq of 125I-m-IBG, whereas no toxic effect on SK-N-MC cells was found at the same activity. Moreover, the toxic effect observed in the SK-N-SH line was clearly related to the use of 125I-m-IBG since the same activity of 1,500 KBq of non-coupled 125I was without effect. For the latter line, colony-forming capacity was reduced for activities of 150 and 1,500 KBq of 125I-m-IBG, with respectively 32% and 38% lower survival rates. The cytotoxic effect of labelled m-IBG was, however, limited in non-saturating concentrations because the specific activity used was too low. Moreover, the low number of cells reconcentrating m-IBG is indicative of the heterogeneous cellular composition of the SK-N-SH line.
