Abstract
Neuroblastoma, a malignancy of the developing peripheral nervous system that affects infants and young children, is a complex genetic disease. Over the past two decades, significant progress has been made toward understanding the genetic determinants that predispose to this often lethal childhood cancer. Approximately 1-2% of neuroblastomas are inherited in an autosomal dominant fashion and a combination of co-morbidity and linkage studies has led to the identification of germline mutations in PHOX2B and ALK as the major genetic contributors to this familial neuroblastoma subset. The genetic basis of "sporadic" neuroblastoma is being studied through a large genome-wide association study (GWAS). These efforts have led to the discovery of many common susceptibility alleles, each with modest effect size, associated with the development and progression of sporadic neuroblastoma. More recently, next-generation sequencing efforts have expanded the list of potential neuroblastoma-predisposing mutations to include rare germline variants with a predicted larger effect size. The evolving characterization of neuroblastoma's genetic basis has led to a deeper understanding of the molecular events driving tumorigenesis, more precise risk stratification and prognostics and novel therapeutic strategies. This review details the contemporary understanding of neuroblastoma's genetic predisposition, including recent advances and discusses ongoing efforts to address gaps in our knowledge regarding this malignancy's complex genetic underpinnings.

Abstract
Until recently, the genetic basis of neuroblastoma, a heterogeneous neoplasm arising from the developing sympathetic nervous system, remained undefined. The discovery of gain-of-function mutations in the ALK receptor tyrosine kinase gene as the major cause of familial neuroblastoma led to the discovery of identical somatic mutations and rapid advancement of ALK as a tractable therapeutic target. Inactivating mutations in a master regulator of neural crest development, PHOX2B, have also been identified in a subset of familial neuroblastomas. Other high penetrance susceptibility alleles likely exist, but together these heritable mutations account for less than 10% of neuroblastoma cases. A genome-wide association study of a large neuroblastoma cohort identified common and rare polymorphisms highly associated with the disease. Ongoing resequencing efforts aim to further define the genetic landscape of neuroblastoma.

Abstract
Total colonic aganglionosis is a relatively uncommon form of Hirschsprung's disease (HSCR). It occurs in approximately 2-13 % of HSCR cases and involves the entire colon which is aganglionic but may extend proximally into varying lengths of small bowel. As a result, it should be separated into Total colonic aganglionosis (TCA) [defined as aganglionosis extending from the anus to at least the ileocaecal valve but no more than 50 cm small bowel proximal to the ileocaecal valve] and total colonic and small bowel aganglionosis (TCSA) which may involve very long segments of small bowel aganglionosis. Clinically, TCA appears to represent a different spectrum of disease in terms of presentation and difficulties which may be experienced in diagnosis suggesting a different pathophysiology from the more common forms of HSCR. It is therefore not yet clear whether TCA merely represents a long form of HSCR or a different expression of the disease. A number of differences exist between TCA and other forms of HSCR which require explanation if its ubiquitous clinical features are to be understood. In addition to the usual explanations for the aganglionosis of HSCR, there is some evidence suggesting that in place of being purely congenital, it may represent certain different pathophysiologic mechanisms, some of which may continue to be active after birth. This study reviews what is known about the clinical, radiological and histopathologic differences between TCA and the more frequently encountered recto-sigmoid (or short-segment; S-HSCR) and correlates them with what is currently known about the genetic and molecular biologic background to find possible pathogenetic mechanisms.

Abstract
The neurocristopathy syndrome occurs because of a germline mutation of the paired-like homeobox 2b (PHOX2B) gene at 4p12, a neurogenesis regulator gene. The result is abnormal neural crest cell development resulting in congenital central hypoventilation syndrome, Hirschsprung disease, and neuroblastoma (NB), which is often multifocal and disseminated in its presentation. Previously, such widespread disease was regarded as highly aggressive and treated either with palliative intent or, conversely, with very intense, high-dose chemotherapy. We now present a patient who had neurocristopathy syndrome who had multifocal NB associated with an underlying germline PHOX2B mutation. He was treated conservatively with surgery and low-dose chemotherapy. After treatment he had extensive residual disease that has continued to mature despite no further treatment. A literature review identified 26 similar patients presenting with multifocal NB as part of the neurocristopathy syndrome. In all cases the NB behaved in an indolent manner with no deaths from tumor reported when patients received appropriate treatment. These provocative findings suggest for the first time that children who have neurocristopathy-associated NB should be treated conservatively, despite the aggressive appearance of their disease.

Total colonic aganglionosis (TCA) is a relatively uncommon form of Hirschsprung disease (HSCR), occurring in approximately 2%-13% of cases. It can probably be classified as TCA (defined as aganglionosis extending from the anus to at least the ileocecal valve, but not >50 cm proximal to the ileocecal valve) and total colonic and small bowel aganglionosis, which may involve a very long segment of aganglionosis. It is not yet clear whether TCA merely represents a long form of HSCR or a different expression of the disease. There are many differences between TCA and other forms of HSCR, which require explanation if its ubiquitous clinical features are to be understood. Clinically, TCA appears to represent a different spectrum of disease in terms of presentation and difficulties that may be experienced in diagnosis, suggesting a different pathophysiology from the more common forms of HSCR. There is also some evidence suggesting that instead of being purely congenital, it may represent certain different pathophysiologic mechanisms. This study, in addition to reviewing current understanding and differences between TCA and the more frequently encountered rectosigmoid (or short-segment) expression, correlates them with what is currently known about the genetic and molecular biological background. Moreover, it reviews current outcomes to find consensus on management.

Abstract
We report the case of an 8-year-old boy with the phenotypic features of Coffin-Siris syndrome diffuse hypertrichosis, flat occiput, scant scalp hair, flat supraorbital arch, triangular eyebrows, horizontal palpebral fissure, anteverted nares, triangular philtrum, coarse lips, high-arched palate, micrognathia, low set and dorsaly rotated ears, short neck, wide thorax, widely set nipples, transverse palmar crease, psychomotor delay, urinary malformations (paraurethral diverticulum, hypoplasia of left kidney associated with vesicoureteral reflux grade 3-4), bilateral inguinal hernia, and dorsolumbar kyphoscoliosis. In the follow-up he presented a retroperitoneal neuroblastoma. Although this type of tumor has been referred to develop in several genetic and mutimalformative syndromes, it seems that present association has not been previously reported.

Abstract
Hirschsprung's disease (HSCR) is a complex congenital disorder which, from a molecular perspective, appears to result due to disruption of normal signalling during development of enteric nerve cells, resulting in aganglionosis of the distal bowel. Associated congenital anomalies occur in at least 5-32% (mean 21%) of patients and certain syndromic phenotypes have been linked to distinct genetic sites, indicating underlying genetic associations of the disease and probable gene-gene interaction in its pathogenesis. Clear-cut associations with HSCR include Down's syndrome, dominant sensorineural deafness, Waardenburg syndrome, neurofibromatosis, neuroblastoma, phaeochromocytoma, the MEN type IIB syndrome and other abnormalities. Individual anomalies vary from 2.97% to 8%, the most frequent being the gastrointestinal tract (GIT) (8.05%), the central nervous system (CNS) and sensorineural anomalies (6.79%) and the genito-urinary tract (6.05%). Other associated systems include the musculoskeletal (5.12%), cardiovascular systems (4.99%), craniofacial and eye abnormalities (3%) and less frequently the skin and integumentary system (ectodermal dysplasia) and syndromes related to cholesterol and fat metabolism. In addition to associations with neuroblastoma and tumours related to MEN2B, HSCR may also be associated with tumours of neural origin such as ganglioneuroma, ganglioneuroblastoma, retinoblastoma and tumours associated with neurofibromatosis and other autonomic nervous system disturbances. The contribution of the major susceptibility genes on chromosome 10 (RET) and chromosome 13 (EDNRB) is well established in the phenotypic expression of HSCR. Whereas major RET mutations may result in HSCR by haploinsufficiency in 20-25% of cases, the etiology of the majority of sporadic HSCR is not as clear, appearing to arise from the combined cumulative effects of susceptibility loci at critical genes controlling the mechanisms of cell proliferation, differentiation and maturation. In addition, potential "modifying" associations exist with chromosome 2, 9, 20, 21 and 22, and we explore the importance of certain flanking genes of critical areas in the final phenotypic expression of HSCR.

Abstract
The detection of adrenal lesions has increased with the expanding use of cross-sectional imaging. Magnetic resonance (MR) imaging is often useful for characterizing adrenal masses. Adrenal masses can be classified into various groups on the basis of the presence of intracellular lipid, macroscopic fat, hemorrhage, and cystic changes and the vascularity and shape of the tumor. These imaging features can be used by the radiologist to suggest or confirm a diagnosis for most adrenal masses, including adenoma, hyperplasia, simple and complicated cysts, lymphangioma, myelolipoma, pheochromocytoma, hemorrhage, cortical carcinoma, neuroblastoma, lymphoma, and metastases. Adenomas and metastases are common, and a decrease in signal intensity on out-of-phase images can be used to differentiate between them. Carcinoma is a possible diagnosis if that decrease in signal intensity is heterogeneous. Benign disease is diagnosed if macroscopic fat or a homogeneous cystlike lesion is seen. Recognition of the typical MR imaging features is important because it often changes the treatment approach and may obviate surgery.

Abstract
Neuroblastoma, a neoplasm of neural crest cell origin, occasionally presents in association with other neural crest abnormalities such as Hirschsprung disease, congenital central hypoventilation, autonomic disturbances, and other tumors. These associations have been termed "neurocristopathy syndromes." In the past, chemotherapy has not been considered for patients with neurocristopathy-associated neuroblastoma because of their complicated medical problems. The authors describe two patients with neurocristopathy syndromes from our institution who underwent surgery and standard chemotherapy treatment of their intermediate-risk neuroblastoma. They represent two of only three long-term disease-free survivors of neurocristopathy-associated neuroblastoma reported in the literature.

Abstract
Neuroblastoma, ganglioneuroblastoma, and ganglioneuroma are tumors of the sympathetic nervous system that arise from primitive sympathogonia and are referred to collectively as neuroblastic tumors. They arise wherever sympathetic tissue exists and may be seen in the neck, posterior mediastinum, adrenal gland, retroperitoneum, and pelvis. The three tumors differ in their degree of cellular and extracellular maturation; immature tumors tend to be aggressive and occur in younger patients (median age, just under 2 years), whereas mature tumors occur in older children (median age, approximately 7 years) and tend to behave in a benign fashion. The most benign tumor is the ganglioneuroma, which is composed of gangliocytes and mature stroma. Ganglioneuroblastoma is composed of both mature gangliocytes and immature neuroblasts and has intermediate malignant potential. Neuroblastoma is the most immature, undifferentiated, and malignant tumor of the three. Neuroblastoma, however, may have a relatively benign course, even when metastatic. Thus, these neuroblastic tumors vary widely in their biologic behavior. Features such as DNA content, tumor proto-oncogenes, and catecholamine synthesis influence prognosis, and their presence or absence aids in categorizing patients as high, intermediate, or low risk. Treatment consists of surgery and, usually, chemotherapy. Despite recent advances in treatment, including bone marrow transplantation, neuroblastoma remains a relatively lethal tumor, accounting for 10% of pediatric cancers but 15% of cancer deaths in children.

Abstract
We report on a male infant with the rare combined occurrence of congenital central hypoventilation syndrome (CCHS or Ondine's curse), Hirschsprung's disease (HD), and neuroblastoma. Current therapeutical options leave no doubt that children with isolated forms of CCHS, HD, or neuroblastoma must be treated, but management decisions and the ethical dilemma become more difficult with the presence of multiple neurocristopathies. Our patient was dependent on mechanical ventilation and total parenteral nutrition, when a neuroblastoma was diagnosed at age 5 months. We initiated an attempt at curative chemotherapy. The tumor failed to respond to recommended chemotherapeutic regimens, and the patient died at 11 months of age. We emphasize the importance of screening CCHS patients for associated illnesses such as neuroblastoma and ganglioneuroblastoma at time of diagnosis.

Abstract
Hirschsprung disease (HSCR, aganglionic megacolon) is the main genetic cause of functional intestinal obstruction with an incidence of 1/5000 live births. This developmental disorder is a neurocristopathy and is characterised by the absence of the enteric ganglia along a variable length of the intestine. In the last decades, the development of surgical approaches has dramatically decreased mortality and morbidity, which has allowed the emergence of familial cases. HSCR appeared to be a multifactorial malformation with low, sex dependent penetrance and variable expression according to the length of the aganglionic segment, suggesting the involvement of one or more gene(s) with low penetrance. So far, eight genes have been found to be involved in HSCR. This frequent congenital malformation now stands as a model for genetic disorders with complex patterns of inheritance.

A 15-year-old boy with neuroblastoma associated with Poland syndrome is presented. He was admitted with a 2-month history of progressive back pain and a 3-day history of weakness of the lower extremities, encopresis and enuresis. On physical examination, in addition to paraplegia, absence of the pectoralis major muscle was diagnosed on the right side of his chest. A large heterogeneous mass in the right side of the thorax was revealed on computerized tomography. Neuroblastoma was diagnosed on histopathological analysis of the mass. To the authors' knowledge this is the first case of neuroblastoma associated with Poland syndrome in the literature.

Abstract
Neuroblastoma has several clinical and molecular genetic parallels with the other paediatric embryonal tumours, such as retinoblastoma, including a hereditary form of the disease. We hypothesised that neuroblastoma susceptibility is due to germline mutations in a tumour suppressor gene and that this predisposition gene may be involved in sporadic neuroblastoma tumorigenesis as well. We therefore aimed to localise the familial neuroblastoma predisposition gene by linkage analysis in neuroblastoma kindreds. Eighteen families segregating for neuroblastoma were ascertained for candidate locus linkage analysis. Although many of the 49 affected individuals in these families were diagnosed as infants with multifocal primary tumours, there was marked clinical heterogeneity. We originally hypothesised that familial neuroblastoma predisposition would map to the telomeric portion of chromosome band 1p36, a genomic region likely to contain a sporadic neuroblastoma suppressor gene. However, neuroblastoma predisposition did not map to any of eight polymorphic markers spanning 1p36.2-.3 in three large kindreds. In addition, there was strong evidence against linkage to two Hirschsprung disease susceptibility genes (RET and EDNRB), a condition that can cosegregate with neuroblastoma as in one of the kindreds tested here. We conclude that the neuroblastoma susceptibility gene is distinct from the 1p36 neuroblastoma suppressor and two of the currently identified Hirschsprung disease susceptibility genes.

Abstract
PURPOSE This report describes a female infant with stage 4 multifocal ganglioneuroblastoma with gastric involvement. PATIENT The patient had a right cervical tumor, a left posterior mediastinal tumor, bilateral adrenal tumors, and bony and bone marrow metastases. The tumor cells were diploid and lacked N-myc gene amplification. The gastric involvement, which did not produce clinical symptoms, was only detected by meticulous exploration during laparotomy. RESULTS Our patient achieved only a partial response to alternating cycles of cyclophosphamide, vincristine, and adriamycin; and etoposide and cisplatin. She currently has stable, unresectable disease with elevated catecholamines. CONCLUSIONS Multifocal ganglioneuroblastomas may arise from either neuroblastic rests or aberrant deposits of neuroblasts. The latter mechanism may have accounted for our patient's gastric tumor. Patients with multifocal ganglioneuroblastomas warrant meticulous radiographic and surgical evaluation to completely document the full extent of disease, and to ensure appropriate staging and therapy.

Abstract
Two-hundred-and-fifty patients were registered in a population-based study of neuroblastomas in Denmark in the period 1943-80. The major epidemiological findings were an increased incidence with an unchanged mortality rate during the study period. The increase in incidence related solely to children 0-4 years of age and was most pronounced in infants under 1 year of age. Several reasons for the observed epidemiological rates include (i) changes in the composition of the population, (ii) improved diagnostic procedures, (iii) a shift in the diagnostic criteria, and (iv) an increase in environmental carcinogens of importance in the induction of neuroblastoma. Associated with an increased risk were lower socio-economic levels and young or advanced parental age, suggesting the importance of environmental as well as genetic factors for the induction of neuroblastoma. The epidemiological findings of an increased incidence with an unchanged mortality rate, which suggests the inclusion of borderline lesions in recent years, are of major importance in interpreting the results of mass screening for the disease. The clinical findings in 253 patients treated in Denmark from 1943 to 1980 (including 5 patients resident outside Denmark and excluding 2 patients without available hospital records) were analysed. The major finding was a zero-time shift, that is, earlier diagnosis of the disease during the study period, with increasing survival rates from decade to decade mostly due to a better age and stage distribution, a zero-time shift which was also apparent in the changes of the symptomatology. Independent prognostic variables were age, stage, and treatment with chemotherapy for children over 1 year of age with stage II disease, and for infants with stages III-IV disease. Analysis of data from a subset of the 253 children suggested that high proliferative activity detected by flow cytometry may be an important prognostic variable. The study also suggests that the pattern of metastatic spread might have changed as a consequence of prolonged survival obtained by improved treatment modalities, stressing the importance of a high frequency of autopsy among cancer patients. Hypotheses generated by the study included (i) that most neuroblastomas might be congenital, (ii) that the age influence on prognosis might be explained in terms of growth rate, cell cycle transit time, and duration of the disease, and (iii) that some neuroblastomas might be borderline lesions.

Abstract
Hirschsprung disease (HSCR) is a frequent congenital disorder (1 in 5,000 newborns) of unknown origin characterized by the absence of parasympathetic intrinsic ganglion cells of the hindgut. Taking advantage of a proximal deletion of chromosome 10q (del 10q11.2-q21.2) in a patient with total colonic aganglionosis, and of a high-density genetic map of microsatellite DNA markers, we performed genetic linkage analysis in 15 non-syndromic long-segment and short-segment HSCR families. Multipoint linkage analysis indicated that the most likely location for a HSCR locus is between loci D10S208 and D10S196, suggesting that a dominant gene for HSCR maps to 10q11.2, a region to which other neural crest defects have been mapped.

Abstract
Of all human tumors, neuroblastomas bear the most prominent genetic changes. Amplifications and deletions of chromosomal DNA can be identified by light microscopy on chromosomal spreads of neuroblastoma cells with remarkable frequency and consistency. Consequently, extensive studies have been undertaken to elucidate the molecular basis of these cytogenetic changes. A rich body of information has accumulated on the role played by dominant oncogenes and recessive tumor suppressor genes in the pathogenesis of this disease. Most notably, it was found that amplification of N-myc is responsible for the presence of double minutes and homogeneously staining regions in neuroblastoma chromosomes. It has also been discovered that N-myc amplification is a prognostic sign of malignancy. More recently, recessive genetic alterations in neuroblastoma, such as deletion of putative tumor-suppressing genes have received increasing attention, and considerable efforts are being made to identify such genetic elements. Finally, the susceptibility of neuroblastoma cells to differentiating stimuli has made them a popular in vitro system for neurobiological and pharmacological research. The need for suitable in vivo systems has spurred the development of several animal models employing tumor viruses and transgenic technologies.
