Purpose: As a scoping review, evaluate the literature on the presentations, genetics, and therapies for neuroblastoma in adult patients. Methods: We searched four databases for studies reporting adults with neuroblastoma. Cohort studies, case series, and case reports were synthesized qualitatively. Progression-free and overall survival were compared amongst cohort studies. Results: Of 2287 unique records, 136 studies published in 141 articles were included. A total of 679 patients were included. On review of individual patient-level data, the adrenal gland and retroperitoneum were the most common primary site (47.3%). MYCN was rarely amplified: seven studies reported zero patients with MYCN amplified, two studies with a single patient, and one study with 3/7 patients. Adult patients appear to show a high frequency of somatic mutations, specifically ALK (42%) and ATRX (58%). Registry data of included studies showed 5-year overall survival to be 36.3% in adults aged ≥20 years. Conclusion: Of nearly 700 cases of adult neuroblastoma published in the literature, the most common primary site is the adrenals or retroperitoneum. Relative to pediatric cases, adult cases demonstrate a considerable rate of somatic mutations such as ALK and ATRX. Registry data showed 5-year survival of 36%. Future studies evaluating targeted therapies in larger samples are needed.

The details of the IRB/oversight body that provided approval or exemption for the research described are given below:

Only publicly available human data from published studies were used for this review. All published studies were cited in the manuscript of the study.

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.
