Abstract
OBJECTIVE The aim of this study was to examine the longitudinal impact of self-efficacy to cope with cancer on the cancer-related coping reactions of breast cancer patients and vice versa. DESIGN AND MAIN OUTCOMES MEASURES Data from the BOUNCE Project (https://www.bounce-project.eu/) were used to address the hypotheses. Participants (N = 403) were enrolled in the study a few weeks after surgery or biopsy. Coping self-efficacy was assessed at baseline and six months later (M6). Cancer-related coping was assessed three (M3) and nine months (M9) after baseline. The analyses were performed using structural equation modeling with Mplus 8.6. RESULTS Baseline coping self-efficacy predicted all M3 coping reactions, while M6 coping self-efficacy also predicted changes in all but one M9 coping reaction. Moreover, one of the M3 coping reactions, that is, hopelessness/helplessness, predicted the changes in M6 coping self-efficacy. The relation between coping self-efficacy and one coping reaction (i.e. cognitive avoidance) was rather weak. Stability paths from M3 to M9 coping reactions were moderate to high. CONCLUSION The relationship between self-efficacy to cope with cancer and cancer-related coping is complex. New theoretical models are needed to more accurately describe the diverse aspects of this association.

Abstract
Breast cancer (BC) remains the most diagnosed cancer in women, accounting for 12% of new annual cancer cases in Europe and worldwide. Advances in surgery, radiotherapy and systemic treatment have resulted in improved clinical outcomes and increased survival rates in recent years. However, BC therapy-related cardiotoxicity, may severely impact short- and long-term quality of life and survival. This study presents the CARDIOCARE platform and its main components, which by integrating patient-specific data from different categories, data from patient-oriented eHealth applications and wearable devices, and by employing advanced data mining and machine learning approaches, provides the healthcare professionals with a valuable tool for effectively managing BC patients and preventing or alleviating treatment induced cardiotoxicity.Clinical Relevance- Through the adoption of CARDIOCARE platform healthcare professionals are able to stratify patients for their risk for cardiotoxicity and timely apply adequate interventions to prevent its onset.

Abstract
OBJECTIVE This study aimed to examine whether self-efficacy to cope with cancer changes over time in patients with breast cancer and whether these potential changes are similar across patients. It also aimed to examine whether these trajectories are related to patient psychological well-being and overall quality of life. METHODS Participants (N = 404) from four countries (i.e. Finland, Israel, Italy, and Portugal) were enrolled in the study few weeks after breast surgery or biopsy. Self-efficacy to cope with cancer was assessed at baseline, six and 12 months later. Well-being indices were assessed at baseline, 12 and 18 months later. RESULTS Using Latent Class Growth Analysis, two groups of patients were identified. The majority of patients reported high levels of self-efficacy to cope, which increased over time. For almost 15% of the patients, however, self-efficacy declined over time. Diminishing levels of self-efficacy to cope predicted worse levels of well-being. The pattern of self-efficacy changes and their relationships to well-being was consistent across countries. CONCLUSION Monitoring self-efficacy to cope with cancer is probably important in order to detect alarming changes in its levels, as a declining self-efficacy to cope may serve as a signal of the need for intervention to prevent adaptation difficulties.

Abstract
The role of self-efficacy to cope with breast cancer as a mediator and/or moderator in the relationship of trait resilience to quality of life and psychological symptoms was examined in this study. Data from the BOUNCE Project ( https://www.bounce-project.eu/ ) were used. Women diagnosed with and in treatment for breast cancer (N = 484), from four countries, participated in the study. Trait resilience and coping self-efficacy were assessed at baseline (soon after the beginning of systemic treatment), and outcomes (quality of life, psychological symptoms) 3 months later. Hierarchical regression, mediation, moderation, and conditional (moderated) mediation and moderation analyses were performed to examine the study hypotheses. Coping self-efficacy mediated the impact of trait resilience. In addition, higher levels of resilience in combination with higher levels of coping self-efficacy were associated with better outcomes. Country of origin had no impact on these results. Overall, it seems that coping self-efficacy is a key factor that should be taken into account for research and intervention efforts in cancer.

Abstract
The heterogeneity of COVID-19 experience and response for each individual is irrefutable; nevertheless, similarities can be observed between countries with respect to people's psychological responses. The main aim of this Commentary is to provide a cultural perspective of the sources of trauma, at the individual and social level, in three different countries: Italy, US and UK. The evidence from previous outbreaks, such as SARS, H1N1 flu, Ebola, and the ongoing Italian, the US, and the UK experience of COVID-19 shows that COVID-19 has introduced not only an individual trauma but also a collective trauma, that researchers should attend to now and in future global emergencies. Future clinical interventions should aim to reconnect dissociated parts both in the individual and in society. This commentary discusses four potential sources of trauma: high-stakes decision fatigue in healthcare professionals, traumatic grief, and bereavement in people who have lost loved ones, loss of roles and identity, and social divisions related to economic shutdown.

Abstract
PURPOSE The development of the adjuvant therapy requires that clinicians and patients should discuss the magnitude of benefit of treatment for individual patient, estimating the pros and cons and the personal preferences. The aim of the present study was to determine the preferences of women treated with adjuvant hormonal therapy (HT) for breast cancer. METHODS The analyses were conducted into three different groups of early breast cancer patients to evaluate the survival benefit needed to make treatment worthwhile before starting HT (A), after a few months from the beginning (B) and after several years of HT (C). The questionnaires, showing hypothetical scenarios based on potential survival times and rates without HT, were used to determine the lowest gains women judged necessary to make the treatment worthwhile. RESULTS A total of 452 patients were included in the study: 149 in group A, 150 in group B and 153 in group C. In group C, 65% of patients were receiving HT with aromatase inhibitors (with or without a LHRH analogue). In the groups A, B, C 8%, 20% and 26%, respectively, received adjuvant chemotherapy. Overall, 355 women (79%) had children. The responses were quite similar between the three groups. A median gain of 10 years was judged necessary to make adjuvant HT worthwhile based on the hypothetical scenario of untreated mean survival time of 5 and 15 years. Median gain of 20% more women surviving was judged necessary to make adjuvant HT worthwhile based on an untreated 5-year survival rate expectation of 60%. Cognitive dysfunction was considered the side effect least compatible with the continuation of treatment in all three groups. CONCLUSIONS This is a large study of patient preferences on HT. Compared with other studies with similar design, the patients included in the present study required larger benefits to make adjuvant therapy worthwhile.

Abstract
Background A novel approach suggested that cognitive and dispositional features may explain in depth the health behaviors adoption and the adherence to prevention programs. The Health Orientation Scale (HOS) has been extensively used to map the adoption of health and unhealthy behaviors according to cognitive and dispositional features. Coherently, the main aim of the current research was to assess the factor structure of the Italian version of the HOS using exploratory and confirmatory factor analysis and testing the construct validity of the scale by assessing differences in health orientations between tobacco cigarette smokers and nonsmokers. Method The research protocol was organized in two studies. Study 1 evaluated the dimensionality of the HOS in a sample of Northern Italian healthy people. Three hundred and twenty-one participants were enrolled; they were 229 women (71.3%) and 92 men (28.7%). In Study 2, the factor structure and construct validity of the HOS Italian version was assessed trough confirmatory factor analysis using a tobacco cigarette smokers and nonsmokers population. Two hundred and nineteen participants were enrolled; they were 164 women (75.2%) and 55 men (24.8%). Results In Study 1, a seven factors solution was obtained explaining 60% of cumulative variance instead of 10 factors solution of the original version of the HOS. In Study 2, the factor structure of the Italian version of the HOS was confirmed and applied to the smokers and nonsmokers; nonsmokers reported higher values than smokers in Factor 1 (MHPP) [t (208) = − 2.739 p < .007] (CI 95–4.96% to −.809), Factor 2 (HES) [t (209) = − 3.387 p < .001] (CI 95–3.93% to -. 1.03), Factor 3 (HIC) [t(213) = − 2.468 p < .014] (CI 95–2.56% to −.28) and Factor 7 (HEX) [t(217) = − 3.451 p < .001] (CI 95%- 1.45 to .39). Conclusions Results of the Italian adaptation of HOS lead to a partial redistribution of items and confirmed 7 subscales to distinguish psycho-cognitive dispositional dimensions involved in health orientation styles.

Abstract
Background: The prognostic impact of segmental chromosome alterations (SCAs) in children older than 1 year, diagnosed with localised unresectable neuroblastoma (NB) without MYCN amplification enrolled in the European Unresectable Neuroblastoma (EUNB) protocol is still to be clarified, while, for other group of patients, the presence of SCAs is associated with poor prognosis. Methods: To understand the role of SCAs we performed multilocus/pangenomic analysis of 98 tumour samples from patients enrolled in the EUNB protocol. Results: Age at diagnosis was categorised into two groups using 18 months as the age cutoff. Significant difference in the presence of SCAs was seen in tumours of patients between 12 and 18 months and over 18 months of age at diagnosis, respectively (P=0.04). A significant correlation (P=0.03) was observed between number of SCAs per tumour and age. Event-free (EFS) and overall survival (OS) were calculated in both age groups, according to both the presence and number of SCAs. In older patients, a poorer survival was associated with the presence of SCAs (EFS=46% vs 75%, P=0.023; OS=66.8% vs 100%, P=0.003). Moreover, OS of older patients inversely correlated with number of SCAs (P=0.002). Finally, SCAs provided additional prognostic information beyond histoprognosis, as their presence was associated with poorer OS in patients over 18 months with unfavourable International Neuroblastoma Pathology Classification (INPC) histopathology (P=0.018). Conclusions: The presence of SCAs is a negative prognostic marker that impairs outcome of patients over the age of 18 months with localised unresectable NB without MYCN amplification, especially when more than one SCA is present. Moreover, in older patients with unfavourable INPC tumour histoprognosis, the presence of SCAs significantly affects OS.

Abstract
BACKGROUND Inflammatory bowel diseases are chronic conditions requiring medication throughout life to treat the disease and control the risk of relapse and colorectal cancer. Adherence to prescribed drugs is therefore crucial to their management. AIM To identify determinants and potential risk factors of non-adherence in inflammatory bowel disease patients. METHODS An anonymous 24-item questionnaire (available online as Supplementary material) was administered to 485 out-patients attending a tertiary referral centre. RESULTS Sixty-one per cent of the patients reportedly adhered to their treatment. No differences emerged between inflammatory bowel disease and socio-demographic characteristics other than age, non-adherence being significantly associated with cases under 40 years (43% vs. 34%, P = 0.041). The most common reasons for non-adherence vs. adherence were forgetfulness (61% vs. 44%, P = 0.000), disease remission (25% vs. 10%, P = 0.000), recent diagnosis (24% vs. 15%, P = 0.000) and full-time employment (55% vs. 26%, P = 0.000). Oral therapy was associated with a significantly better adherence than rectal therapy (60% vs. 32%, P = 0.001). Communication affects patient adherence: a significant interaction was found for adherence and patients <40 years who had a good relationship with their doctors. CONCLUSIONS Risk factors for non-adherence are younger age, busy working life, recent diagnosis and disease remission. Good communication with the doctor might improve adherence.

Abstract
The p73 gene is a p53 homologue localized at 1p36.3, a chromosomal region frequently deleted in neuroblastoma. p73 was originally considered an oncosuppressor gene. However, it was soon realized that its mode of action did not resemble that of a classic anti-oncogene. The recent discovery of N-terminal truncated isoforms, with oncogenic properties, showed that p73 has a 'two in one' structure. Indeed, the full-length variants are strong inducers of apoptosis while the truncated isoforms inhibit the pro-apoptotic activity of p53 and of the full-length p73. This review summarizes some aspects of p73 biology with particular reference to its possible role in neuroblastoma.

Abstract
PURPOSE Therapy stratification based on genetic markers is becoming increasingly important, which makes commitment to the highest possible reliability of the involved markers mandatory. In neuroblastic tumors, amplification of the MYCN gene is an unequivocal marker that indicates aggressive tumor behavior and is consequently used for therapy stratification. To guarantee reliable and standardized quality of genetic features, a quality-assessment study was initiated by the European Neuroblastoma Quality Assessment (ENQUA; connected to International Society of Pediatric Oncology) Group. MATERIALS AND METHODS One hundred thirty-seven coded specimens from 17 tumors were analyzed in 11 European national/regional reference laboratories using molecular techniques, in situ hybridization, and flow and image cytometry. Tumor samples with divergent results were re-evaluated. RESULTS Three hundred fifty-two investigations were performed, which resulted in 23 divergent findings, 17 of which were judged as errors after re-evaluation. MYCN analyses determined by Southern blot and in situ hybridization led to 3.7% and 4% of errors, respectively. Tumor cell content was not indicated in 32% of the samples, and 11% of seemingly correct MYCN results were based on the investigation of normal cells (eg, Schwann cells). Thirty-eight investigations were considered nonassessable. CONCLUSION This study demonstrated the importance of revealing the difficulties and limitations for each technique and problems in interpreting results, which are crucial for therapeutic decisions. Moreover, it led to the formulation of guidelines that are applicable to all kinds of tumors and that contain the standardization of techniques, including the exact determination of the tumor cell content. Finally, the group has developed a common terminology for molecular-genetic results.

Abstract
BACKGROUND We previously reported that stage 3 neuroblastoma comprises (i) a low-risk group including all infants (age 0-11 months) as well as older children with non-abdominal primaries, and (ii) a high-risk group made up of children >1 year of age with abdominal primaries. Aggressive chemotherapy was effective only in the latter group. PATIENTS AND TREATMENT On this basis, in 1990 we designed a new protocol by which all low-risk patients received standard-dose chemotherapy, while the high-risk ones received very aggressive chemotherapy. RESULTS Between November 1990 and December 1997 a total of 95 eligible and evaluable children were enrolled: 47 were low-risk (35 infants and 12>1 year of age at diagnosis and having non-abdominal primaries), and 48 were high-risk (being >1 year of age and having abdominal primaries). Of the 47 low-risk patients, five relapsed and four subsequently died. The 5-year overall survival (OS) was 91%. Of the 48 patients in the high-risk group, 22 relapsed or progressed, 18 of whom died from their disease and two from toxicity, and one was lost to follow-up. The 5-year OS was 60%. Univariate analysis showed that age, site of primary, risk-group, urine vanillylmandelic excretion, plasma levels of lactate dehydrogenase, ferritin and neurone-specific enolase, and MYCN status correlated with outcome. However, multivariate analysis showed that only MYCN status retained prognostic value. CONCLUSIONS In low-risk stage 3 neuroblastoma, standard-dose chemotherapy is associated with an excellent chance of being cured. Aggressive chemotherapy is effective for high-risk patients, but results are still unsatisfactory. MYCN gene amplification is a prognostic indicator for most, but not all, treatment failures.

Abstract
The p73 gene is a p53 homologue which induces apoptosis and inhibits cell proliferation. Although p73 maps at 1p36.3 and is frequently deleted in neuroblastoma (NB), it does not act as a classic oncosuppressor gene. In developing sympathetic neurons of mice, p73 is predominantly expressed as a truncated anti-apoptotic isoform (DeltaNp73), which antagonizes both p53 and the full-length p73 protein (TAp73). This suggests that p73 may be part of a complex tumor-control mechanism. To determine the role of DeltaNp73 in NB we analyzed the pattern of expression of this gene in vivo and evaluated the prognostic significance of its expression. Our results indicate that DeltaNp73 expression is associated with reduced apoptosis in a NB tumor tissue. Expression of this variant in NB patients significantly correlates with age at diagnosis and VMA urinary excretion. Moreover it is strongly associated with reduced survival (HR=7.93; P<0.001) and progression-free survival (HR=5.3; P<0.001) and its role in predicting a poorer outcome is independent from age, primary tumor site, stage and MYCN amplification (OS: HR=5.24, P=0.012; PFS: HR=4.36, P=0.005). In conclusion our data seem to indicate that DeltaNp73 is a crucial gene in neuroblastoma pathogenesis.

Abstract
PURPOSE To determine the relationship between multiple genetic features, tumor morphology, and prognosis in neuroblastoma. PATIENTS AND METHODS The genetic alterations and morphologic features that underpin three histopathologic risk classifications were analyzed in 108 neuroblastoma patients. Tumors were subdivided into four groups based on the three most frequent and prognostically significant genetic alterations (17q gain, 1p deletion, and MYCN amplification), and all other genetic, morphologic, and clinical data were analyzed with respect to these groups. RESULTS Our analyses identify three nonoverlapping tumor types with distinct genetic and morphologic features, defined here as types 1, 2, and 3. Type 1 tumors show none of the three significant genetic alterations and have good prognosis. Both type 2 (17q gain only or 17q gain and 1p del) and type 3 (17q gain, 1p del, and MYCN amplification) tumors progress. However, these tumor types are distinguished clinically by having significantly different median age at diagnosis and median progression-free survival (PFS). Multivariate analysis indicates that 17q gain is the only independent prognostic factor among all genetic, histopathologic, and clinical factors analyzed. Among histopathologic risk systems, the International Neuroblastoma Pathology Classification was the best predictor of PFS. CONCLUSION Our results indicate that specific combinations of genetic changes in neuroblastoma tumors contribute to distinct morphologic and clinical features. Furthermore, the identification of two genetically and morphologically distinct types of progressing tumors suggests that possibilities for different therapeutic regimens should be investigated.

Abstract
BACKGROUND Neuroblastoma is the most common extracranial malignant solid tumor in children under 5 years and is characterized by a wide clinical and biological heterogeneity, from spontaneously regressive forms to cancers with a rapid and fatal progression. MYCN oncogene amplification is considered the most important prognostic factor to evaluate survival and therapeutic choices in these patients. METHODS Here we present a new assay for rapid and accurate measurement of MYCN amplification, based on real-time quantitative PCR with the TaqMan(TM) reaction. The degree of MYCN amplification was derived from the ratio of the MYCN oncogene and the single-copy reference gene, beta-actin. The absolute abundance of these two genes in tumor sample DNA was obtained by extrapolation on external calibration curves generated with reference DNA. RESULTS We found a variable degree of MYCN amplification, from 2 to 29, in 26 of 49 (53%) neuroblastomas. These results were well correlated to those obtained with a competitive PCR assay in the same samples (r = 0. 987). MYCN amplification was associated mainly with advanced cancer stages, and the analysis of overall survival confirmed that the measurement of MYCN amplification is a predictor of patient outcome in neuroblastoma. Patients without MYCN amplification had a cumulative survival significantly higher than patients with low (<9; P = 0.02) and high (>/=9; P = 0.03) oncogene amplification. CONCLUSION The assay is rapid and reproducible and does not require any post-PCR analytical procedure.

Abstract
The tp73 gene, a tp53 homologue, has been sub-regionally mapped at 1p36.3, a chromosomal region frequently deleted in neuroblastoma. Due to its chromosomal localization and to the mono-allelic expression observed in some neuroblastoma cell lines, it was proposed that tp73 might be involved in the pathogenesis of neuroblastoma. Functional assays have demonstrated that tp73 can inhibit cell proliferation and induce apoptosis. The role of this gene in tumorigenesis, however, is still unclear. We analyzed tp73 expression in 95 sporadic neuroblastoma samples by RT-PCR and we detected the tp73 transcript in 46 cases (48.4%), without significant correlation with age, clinical stage or 3-year overall survival. A genetic polymorphism in the 2nd exon of tp73 was utilized to identify the transcribed allele in tumor-cell samples. Expression from only one of the tp73 alleles was found in 13 out of 16 heterozygous tumors, while in 3 samples both alleles were present. Genotype analysis of 73 patients and 150 controls showed a significant deviation (p = 0.0308) from the Hardy-Weinberg equilibrium for a tp73 allele only among neuroblastoma patients. The absence of correlation between tp73 expression and clinical stage, age and survival suggests that this gene does not play an essential function in the clinical course of the disease. However, the distribution of genomic tp73 alleles in patients indicates that a role of this gene in the development of neuroblastoma cannot be completely ruled out. Int. J. Cancer (Pred. Oncol.) 84:365-369, 1999.

Abstract
Familial neuroblastoma occurs rarely. We studied a family with three children; one of them has a disseminated (stage 4) and another has a localized (stage 2) neuroblastoma. We observed subtelomeric locus D1Z2 (1p36) deletion in both tumors by using double-color fluorescence in situ hybridization. The MYNC gene was found in single copy in both tumors. Loss of heterozygosity (LOH) and restriction fragment length polymorphism analyses were performed by using DNA from frozen tumor cells and from microdissected tumor areas excised from paraffin-embedded sections. We detected somatic LOH at locus D1S468 (1p36) in a tumor-cell population with a trisomy 1 of the stage-2 patient. Neuroblastoma cells of the stage-4 patient were diploid and showed allelic loss at the following loci: D1S172, D1S80, D1S94, D1S243, D1S468, D1S214, D1S241, and D1S164. Haplotype study showed that the siblings inherited the same paternal 1p36-->pter chromosome region by homologous recombination and that, in the two tumors, arm 1p of different chromosomes of maternal origin was damaged. Our results suggest that the siblings inherited the predisposition to neuroblastoma associated with paternal 1p36 region and that tumors developed as a consequence of somatic loss of the maternal 1p36 allele.

We studied chromosome 1p loss of heterozygosity (1p-LOH) in 53 neuroblastomas (NBs) using 15 (CA)n repeat loci, which covered a region of 90 cM. We also assessed chromosome 1p36 deletion by fluorescence in situ hybridization (FISH) on interphase nuclei. 1p-LOH was found in 19 (36%, 95% confidence interval (CI) 23-50%) NBs. We detected interstitial and large deletion in both localized and disseminated tumours and in one tumour of a patient at stage 4S. Allelic loss was frequently observed in 1p36 and 1p32 regions. In patients older than 1 year of age (53 versus 13%, P < 0.002) we detected significant chromosome 1p deletion and it was associated with MYCN amplification (P = 0.001). Overall survival (OS) analysis showed that 1p-LOH is predictive of a poor outcome (odds ratio 16.5, 95% CI 5.4-50.9%); therefore, 1p-LOH should be regarded as an additional tumour progression marker in neuroblastoma.

Abstract
Deletion of chromosome 1p and MYCN amplification have been reported as frequent abnormalities in human neuroblastoma. We studied loss of heterozygosity (LOH) in 50 (48 informative) Italian neuroblastoma patients by restriction fragment length polymorphisms (RFLPs) analysis using anonymous and hypervariable region (HVR) sequences. Twelve cases (25%) showed LOH at one or more loci. Locus D1S94 was the most frequently involved in LOH events (8/12) of deleted cases (66.6%). MYCN amplification was observed in 20% of patients which showed a significantly lower event-free survival probability (EFSp) (P = 0.004). We also studied the allelic distribution in the constitutional DNA of neuroblastoma patients (n = 44) and a matched group of healthy Italian subjects (n = 79) for loci D1S112 and D1S94. A significantly (P = 0.01) different allele frequency was detected for the two groups at locus D1S94, but not at D1S112. Moreover, the neuroblastoma population did not confirm the Hardy-Weinberg expectations at the former locus. This observation suggests the existence of an allelotype associated with neuroblastoma susceptibility.

Abstract
Loss of heterozygosity (LOH) and deletion of chromosome 1p are very often found in sporadic neuroblastoma. Nevertheless, very few data are available concerning 1p LOH in familial neuroblastoma. Families with recurrent neuroblastoma are rare and analysis of chromosome 1p in these families might give useful information for identifying the putative neuroblastoma suppressor gene. We used combined cytogenetic and molecular techniques to study 1p LOH in two neuroblastoma families. Family M has 2 out of 3 children with neuroblastoma and family C has 2 children, 1 of whom has neuroblastoma and type 1 neurofibromatosis (NF1). All patients of both families showed tumour cells with chromosome 1p deletion (1pdel), but only the patient from family C also had MYCN gene amplification. In all cases the deleted chromosome 1 was of maternal origin.

Abstract
Neuroblastoma (NB) is a tumor of pediatric age that is associated with high mortality in metastatic stages, although stage IVS patients undergo frequent spontaneous regression. Since apoptosis has been proposed as a possible cause of remission among cancer patients, we tested this hypothesis among both localized and metastatic NB and, in particular, NB metastatic stage IVS. We have assayed 36 localized and 117 metastatic neuroblastomas for evidence of internucleosomal DNA degradation and confirmed DNA fragmentation by the flow cytometric Terminal deoxynucleotidyl Transferase method, which also allowed us to measure DNA content and cell cycle phases. These techniques provided evidence of apoptosis in 18 out of 153 samples (11.8%), that were equally distributed among all stages except IVS, i.e. 11.1% in stage I (2/18), 11.1% in stage II (2/18), 13.2% in stage III (5/38), 13.4% in stage IV (9/67), and 0% in stage IVS (0/12). Tumor tissue samples collected at onset and also at relapse for the same patients showed that apoptosis may occur at relapse. In addition, cells appear to undergo apoptosis independently from N-myc amplification, cell cycle phase and DNA ploidy. In conclusion, apoptosis seems to take place with about an equal frequency for both favourable and unfavourable stages with an exception for IVS. Since DNA fragmentation remained undetected in stage IVS, we suggest that apoptosis is not a mechanism of spontaneous regression for these patients. A better basic understanding of the complex molecular mechanisms and biochemical pathways that control apoptosis in neuroblastoma appears to be necessary.

Abstract
PURPOSE To evaluate the prognostic role of MYCN oncogene amplification in children with neuroblastoma. PATIENTS AND METHODS Of 694 children (age, 0 to 15 years) with previously untreated neuroblastoma, 295 (42%) were evaluated at diagnosis for MYCN gene amplification. RESULTS Clinical characteristics and survival results of 295 patients studied and 399 not studied for MYCN were comparable. In 48 of 295 patients studied for MYCN (16%), the gene was amplified (> or = three gene copies). Amplification was more frequent in children older than 1 year, with abdominal tumor (18% v 7%), advanced disease, normal vanillylmandelic (VMA) urinary excretion, and high lactate dehydrogenase (LDH), ferritin, and neuron-specific enolase (NSE) serum levels. In patients studied for MYCN, the 5-year overall survival (OS) rate was higher for children aged less than 1 year (90% v 44%), with extraabdominal tumor, stage 1 or 2 versus 3 versus 4, and normal NSE, LDH, and ferritin serum levels. Patients with amplified MYCN had a worse OS (odds ratio [OR], 3.38; confidence interval [CI], 2.22 to 5.16). This association held after adjustment for other characteristics. The impact of MYCN amplification was greater in patients with favorable characteristics, in particular age (OR, 10.28 for infants; 2.08 for older children) and stage (OR, 35.3 for stage 1 to 2; 8.41 for stage 3; 1.76 for stage 4). However, of 29 children with stage 4s, all three with amplified MYCN survive. In a multivariate analysis, the prognostic role of MYCN amplification, age, and stage was confirmed, but the size of the effect of MYCN was dependent on age and stage. CONCLUSION MYCN amplification is associated with a worse prognosis in children with neuroblastoma at all ages and stages except 4s. This association is most pronounced in children with otherwise favorable prognostic indicators, and in these children should be considered as an indication for more intensive intervention.

Abstract
Human neuroblastoma (NB) is characterized genetically by deletions of the short arm of chromosome I and by MYCN amplification. Loss of heterozygosity (LOH) has been found frequently for region 1p36. We have studied restriction fragment length polymorphisms (RFLPs) by using anonymous and hypervariable region (HVR) sequences to demonstrate LOH for 1p loci in 50 Italian neuroblastoma patients. Twelve cases (25%) showed LOH at one or more loci. Locus D1S94 was the most frequently involved (8/12 cases with deletion; 67%). MYCN amplification was observed in 20% of the patients. We also studied the allelic distribution in the constitutional DNA of neuroblastoma patients and of healthy Italian subjects for loci D1S112 and D1S94. A significantly (P = 0.01) different allele frequency was detected in the two groups at locus D1S94, but not at D1S112. Furthermore, the NB population was not in Hardy-Weinberg equilibrium at the former locus. This new observation suggests the existence of an allelotype associated with the susceptibility to neuroblastoma.

Abstract
Calcyclin gene, a Ca(2+)-binding protein with homology to S-100, has been found to be expressed at different levels in leukaemic cells and in other tumour cells. We recently reported the expression of the gene in human neuroblastoma (NB) cell lines, and suggested a possible role of calcyclin in cell differentiation. To extend our findings, we investigated the expression of the gene in NB cells induced to differentiate by retinoic acid (RA), using the reverse transcriptase-polymerase chain reaction (RT-PCR) technique. Time-course experiments employing LA-N-5 cells showed that calcyclin mRNA appeared 2 h after RA treatment, long before the cells were blocked in the G1 cell-cycle phase and before the neurite-like structures outgrew from the cell bodies. This suggests the involvement of the gene in the early phase of cell differentiation. Furthermore, we investigated mRNA expression in a series of fresh neuroblastomas. NB tumours showed a heterogeneous pattern of calcyclin expression, although calcyclin seemed to be expressed more frequently in cases with a favourable Shimada histology. We also studied the expression of the protein in formalin fixed and paraffin embedded tissues, by using a specific anticalcyclin antibody. The protein was detected in stromal cells which characterise a more mature histological type, and in nerve sheaths, whereas neuroblasts were negative. The tissue that expressed calcyclin protein showed a Schwann-like differentiation and, unlike S-100 protein, calcyclin was expressed in the perineurium.

Abstract
The promoter region of genes involved in cell growth and differentiation is bound by specific transcription factors which regulate its expression. Our previous study showed that the calcyclin gene, which belongs to the large family of Ca2+-binding proteins, is differently expressed in SK-N-BE(2)C and LA-N-5 neuroblastoma cell lines. We analysed the region upstream the transcription initiation site of the gene before and during retinoic acid (RA)-induced differentiation. Gel-shift analysis showed that the -161,-135 untranslated region is bound by an AP-1-like protein both in SK-N-BE(2)C and LA-N-5 cells. Competition assay demonstrated that AP-2,AP-3 and NF1 transcription factors did not bind in the same region. Calcyclin mRNA is induced in RA-treated LA-N-5 cells and reaches maximal expression at 96 h, suggesting that its gene is involved in cell differentiation. Gel-shift analysis shows a strong signal of binding after 96 h of RA treatment. Our results indicate that RA induces an increase in the binding protein or improves its affinity for the AP-1-like region during neuronal differentiation. These preliminary data suggest that the calcyclin gene is involved in neuronal pathway differentiation and that AP-1-like binding sequence could be one of the gene regions that is under transcriptional factor control during cell differentiation.

Abstract
Molecular and genetic analyses of tumor cell show that cellular oncogenes and suppressor genes are involved in neoplastic transformation. In pediatric tumors oncogenes as N-myc play an important role in the tumor progression. In retinoblastoma, neuroblastoma, Wilms' tumor, and rhabdomyosarcoma loss of heterozygosity for specific chromosome loci has been suggested to be a critical step in cancer development. Oncogene abnormalities can also be useful as a molecular tumor factor to foresee the prognosis of the disease. The present article is a review on the role of the oncogenes and suppressor genes in pediatric solid tumors.

Abstract
Of 567 children with neuroblastoma diagnosed between November 1984 and May 1993 in 21 Italian institutions, 235 (41%) have been evaluated for MYCN oncogene amplification. The amplification (3 or more copies of the gene) was found in 39 patients (17%) and was more frequent in patients aged more than one year, abdominal primary site of the tumor, advanced stages, normal urinary excretion of vanillylmandelic acid (VMA), and high level of LDH, NSE and ferritin. The five-year survival of the 235 patients (62%) was significantly better in patients with normal copy number of MYCN (69% versus 29%). By correlating genomic amplification with clinical and biochemical characteristics, MYCN amplification was found associated with a worse prognosis even when patients were subdivided for age (under and above one year), disease extension (localized operable, localized but inoperable, and disseminated) with exception for Stage IV-S, VMA and homovanillic acid excretion, serum levels of NSE and ferritin, but not of LDH. These data confirm the unfavourable prognostic meaning of MYCN amplification, but are unable to define if it represents a new independent variable.
