Presentation
Overall 75% of cases present within six weeks of birth 4, and over 90% of cases present within the first five years of life. A very small number may present in the adult population 1. [radiopaedia.org]
Clinically, the tumour usually occurs in adults and presents with obstructive symptoms. Our study group comprised 36 adults and children. [pass-prettier.ga]
Importance OMS, also known as dancing eye syndrome, is a rare disorder that presents in early childhood with involuntary rapid eye movements, myoclonic limb jerking, ataxia, and behavioral changes. [cambridge.org]
If it is present in multiple copies (10 or more), it promotes rapid tumor growth and indicates a bad prognosis. [enjoypath.com]
Hirschsprung Disease Hirschsprung disease (aganglionic megacolon) occurs when some of the nerve cells that are normally present in the wall of the intestine do not form properly during fetal development. [cincinnatichildrens.org]

Treatment General : The treatment for ganglioneuroblastoma depends on the spread of the cancer, age, and other risk factors. Possible treatments include surgery, chemotherapy, radiation, stem cell transplant, and immunotherapy. [nutritionhouse.com]

[…] resections “Neuroblastoma with treatment effect” is sufficient May classify metastatic disease if resection/biopsy is pre-treatment ANCILLARY TESTS Immunohistochemistry Neuron-specific enolase (NSE) Most sensitive but least specific Is found at least [basicmedicalkey.com]
Treatment with corticosteroids or corticotropin (ACTH) may control the symptoms. [healio.com]
Prognosis
Certain genetic factors can also affect the prognosis. N-MYC is a proto-oncogene located on chromosome arm 2p. If it is present in multiple copies (10 or more), it promotes rapid tumor growth and indicates a bad prognosis. [enjoypath.com]
Usually seen in advanced disease DNA ploidy Near-diploidy or tetraploidy is associated with worse prognosis Hyperdiploidy is associated with better prognosis Loss of heterozygosity of 1p and 11q Both associated with worse prognosis TrkA (high-affinity [basicmedicalkey.com]
Prognosis of neuroblastoma: Patient over 5 years of age. Any neuroblastoma is considered to have unfavorable histology. Prognosis of neuroblastoma: Patient between 18 months and 5 years of age, inclusive (3). [brainscape.com]

Where this is successful, the prognosis is good. However, in 3-4% of cases, colonic perforation complicates the presentation 2 and this and its sequelae significantly increase both mortality and morbidity. [radiopaedia.org]

Prevention

Changes in either the EDNRB gene or the EDN3 gene disrupt the normal functioning of the endothelin receptor type B or the endothelin 3 protein, preventing them from transmitting signals important for the development of enteric nerves. [ghr.nlm.nih.gov]
This contracted state (sometimes called rectal achalasia) prevents the passage of stools and causes intestinal obstruction and constipation. [liquisearch.com]

Murthy: There’s a good deal of experience that continuous positive airway pressure may allow the patient to avoid intubation by both providing airway distending pressure to prevent collapse and as a general stimulus to breathing. [healio.com]
