Most patients with neuroblastoma present with disseminated disease, which confers a poor prognosis and is associated with a high mortality rate. Tumors in these patients usually have unfavorable pathologic and/or molecular features. The 3-year EFS for high-risk patients treated with conventional chemotherapy, radiation therapy, and surgery is less than 20%. Differentiating agents and dose intensification of active drugs, followed by autologous bone marrow transplant, have been reported to improve the outcome for these patients, contributing to an EFS of 38%. A recent single-arm study of tandem stem cell transplantation reported a 3-year EFS of 58%, but randomized studies of this approach are ongoing.  Neuroblastoma is a rare type of cancer that mostly affects babies and young children. It develops from specialised nerve cells (neuroblasts) left behind from a baby's development in the womb
Shimada et al’s original classification was adopted and integrated into the International Neuroblastoma Pathology Classification (INPC). This was most recently revised.  The INPC system remains age-dependent. noun neuroblastoma A malignant tumor composed of neuroblasts, most commonly in the adrenal neuroblastoma popularity. A pretty common term. Usually people know it's meaning, but prefer to.. Patients younger than 60 months with stroma-poor tumors, an MKI of less than 100/5000, and well-differentiated tumor cellsThe most important of these biologic markers is MYCN. MYCN is an oncogene that is overexpressed in approximately one quarter of cases of neuroblastoma via the amplification of the distal arm of chromosome 2. This gene is amplified in approximately 25% of de novo cases and is more common in patients with advanced-stage disease. Patients whose tumors have MYCN amplification tend to have rapid tumor progression and poor prognosis, even in the setting of other favorable factors such as low-stage disease or 4S disease.Pluripotent sympathetic stem cells migrate and differentiate to form the different organs of the sympathetic nervous system. The normal adrenal gland consists of chromaffin cells, which produce and secrete catecholamines and neuropeptides. Other cells include sustentacular cells, which are similar to Schwann cells, and scattered ganglion cells. Histologically, neural crest tumors can be classified as neuroblastoma, ganglioneuroblastoma, and ganglioneuroma, depending on the degree of maturation and differentiation of the tumor.

Neuroblastomas are cancers that start in early nerve cells (called neuroblasts) of the sympathetic nervous system, so they can be found anywhere along this system. Neuroblastoma is the most common extracranial solid tumor of infancy. It is an embryonal malignancy of the sympathetic nervous system arising from neuroblasts (pluripotent sympathetic cells)

Three neurotrophin receptor gene products, TrkA, TrkB, and TrkC, are tyrosine kinases that code for a receptor of members of the nerve growth factor (NGF) family. Their ligands include p75 neurotrophin receptor (p75NTR) NGF, and brain-derived neurotrophic factors (BDNFs). Interestingly, TrkA expression is inversely correlated with the amplification of the MYCN gene, and the expression of the TrkC gene is correlated with TrkA expression. In most patients younger than 1 year, a high expression of TrkA correlates with a good prognosis, especially in patients with stages 1, 2, and 4S. In contrast, TrkB is more commonly expressed in tumors with MYCN amplification. This association may represent an autocrine survival pathway.In contrast, the completely benign ganglioneuroma is typically composed of mature ganglion cells, Schwann cells, and neuritic processes, whereas ganglioneuroblastomas include the whole spectrum of differentiation between pure ganglioneuromas and neuroblastomas. Because of the presence of different histologic components, the pathologist must thoroughly evaluate the tumor; the regions with different gross appearance may demonstrate a different histology.

In rare instances, individuals with neuroblastoma may develop opsoclonus myoclonus syndrome, which causes rapid eye movements and jerky muscle motions. This condition occurs when the immune system malfunctions and attacks nerve tissue.A relationship between 1p loss of heterozygosity (LOH) and MYCN amplification has been described. Other allelic losses of chromosomes 11q, 14q, and 17q have been reported, suggesting that other tumor suppressor genes may be located in these chromosomes. Loss of heterozygosity at 11q23 has been described and is an independent prognostic factor. Another characteristic of neuroblastoma is the frequent gain of chromosome 1. What is neuroblastoma?

Neuroblastoma is the most common cancer in infants younger than 1 year. It occurs in 1 in 100,000 children and is diagnosed in about 650 children each year in the United States.According to the SEER data, the overall 5-year survival rate for children with neuroblastoma has improved from 24% in 1960-1963 to 55% in 1985-1994.  In part, this increase in survival rate may be due to better detection of low-risk tumors in infants. The survival rate 5 years from diagnosis is approximately 83% for infants, 55% for children aged 1-5 years, and 40% for children older than 5 years. Improvements in diagnostic imaging modalities, medical and surgical management, and supportive care have contributed to the improved survival rates.

Shimada et al developed a histopathologic classification in patients with neuroblastoma.  This classification system was retrospectively evaluated and correlated with outcome in 295 patients with neuroblastoma who were treated by the Children's Cancer Group (CCG). Important features of the classification include (1) the degree of neuroblast differentiation, (2) the presence or absence of Schwannian stromal development (stroma-rich, stroma-poor), (3) the index of cellular proliferation (known as mitosis-karyorrhexis index [MKI]), (4) nodular pattern, and (5) age. Using these components, patients can be classified into the following histology groups: Lo hago por la insignia xd. Neuroblastoma 28 дек. 2017 в 18:32 .

More than 90% of patients have elevated homovanillic acid (HVA) and/or vanillylmandelic acid (VMA) levels detectable in urine. Mass screening studies using urinary catecholamines in neonates and infants in Japan, Quebec, and Europe have demonstrated the ability to detect neuroblastoma before it is clinically apparent. However, most of the tumors identified occur in infants with a good prognosis. None of these studies shows that mass screening decreases deaths due to high-risk neuroblastoma.
Ganglioneuromas are usually removed by surgery and looked at carefully with a microscope to be sure they don’t have areas of malignant cells (which would make the tumor a ganglioneuroblastoma). If the final diagnosis is ganglioneuroma, no other treatment is needed. If it’s found to be a ganglioneuroblastoma, it’s treated the same as a neuroblastoma.Incidence of neuroblastoma is higher in white children than in black children.

Cytogenetically, the presence of double-minute chromatin bodies and homogeneously staining regions correlates with MYCN gene amplification. Deletion of the short arm of chromosome 1 is the most common chromosomal abnormality present in neuroblastoma and confers a poor prognosis. The 1p chromosome region likely harbors tumor suppressor genes or genes that control neuroblast differentiation. Deletion of 1p is more common in near-diploid tumors and is associated with a more advanced stage of the disease. Most of the deletions of 1p are located in the 1p36 area of the chromosome.

The undifferentiated neuroblastomas histologically present as small, round, blue cell tumors with dense nests of cells in a fibrovascular matrix and Homer-Wright pseudorosettes. These pseudorosettes, which are observed in 15-50% of tumor samples, can be described as neuroblasts surrounding eosinophilic neuritic processes. The typical tumor shows small uniform cells with scant cytoplasm and hyperchromatic nuclei. A neuritic process, also called neuropil, is a pathognomonic feature of neuroblastoma cells. NSE, chromogranin, synaptophysin, and S-100 immunohistochemical stains are usually positive. Electron microscopy can be useful because ultrastructural features (eg, neurofilaments, neurotubules, synaptic vessels, dense core granules) are diagnostic for neuroblastoma. Neuroblastoma definition, a malignant tumor of immature nerve cells that usually starts in the autonomic nervous system or adrenal gland and spreads quickly, most often affecting young children Origin and migration pattern of neuroblasts during fetal development explains the multiple anatomic sites where these tumors occur; location of tumors varies with age. Tumors can develop in the abdominal cavity (40% adrenal, 25% paraspinal ganglia) or other sites (15% thoracic, 5% pelvic, 3% cervical tumors, 12% miscellaneous). Infants more commonly present with thoracic and cervical tumors, whereas older children more frequently have abdominal tumors.Several mutations in the PHOX2B gene have been identified in sporadic and familial neuroblastoma. The PHOX2B gene is important for the formation and differentiation of nerve cells. Mutations in this gene are believed to interfere with the PHOX2B protein's role in promoting nerve cell differentiation. This disruption of differentiation results in an excess of immature nerve cells and leads to neuroblastoma. 17.

A study by Challagundla et al reported that exosomic microRNAs released within the neuroblastoma environment affect resistance to chemotherapy.  Several mutations in the ALK gene are involved in the development of sporadic and familial neuroblastoma. The ALK gene provides instructions for making a protein called ALK receptor tyrosine kinase. Although the specific function of this protein is unknown, it appears to play an important role in cell proliferation. Mutations in the ALK gene result in an abnormal version of ALK receptor tyrosine kinase that is constantly turned on (constitutively activated). Constitutively active ALK receptor tyrosine kinase may induce abnormal proliferation of immature nerve cells and lead to neuroblastoma.

According to SEER, incidence decreases every consecutive year up to age 10 years, after which the disease is rare. 
Some neuroblastomas grow and spread quickly, while others grow slowly. Sometimes, in very young children, the cancer cells die for no reason and the tumor goes away on its own. In other cases, the cells sometimes mature on their own into normal ganglion cells and stop dividing (this makes the tumor a benign ganglioneuroma).London WB, Castleberry RP, Matthay KK, et al.

(2006) Inhibition of Human Carcinoma and Neuroblastoma Cell Proliferation by anti c-Myc siRNA // Oligonucleotides, 16, 15—25 Neuroblastoma is a type of cancer that most often affects children. Neuroblastoma occurs when immature nerve cells called neuroblasts become abnormal and multiply uncontrollably to form a tumor. Most commonly, the tumor originates in the nerve tissue of the adrenal gland located above each kidney. Other common sites for tumors to form include the nerve tissue in the abdomen, chest, neck, or pelvis. Neuroblastoma can spread (metastasize) to other parts of the body such as the bones, liver, or skin.
