The first 60 days: Neuroblastoma (paediatric)
Neuroblastoma is a childhood nerve-cell cancer where anti-GD2 antibodies and, recently, GD2 CAR-T have improved survival in high-risk disease. Below, week by week, is what OnCo's record of Neuroblastoma (paediatric) says about the first two months: the order is typical, the timing is yours to ask about. Sections appear only where the record has something to say. Orientation, not medical advice.
What happens now
Staging tests establish exactly what and where the cancer is. Everything else follows from the answers.
Ask which of these were tested and what the results were; see the report reader for what each value means.
These specialties appear in the standard of care for this cancer. In most centres they meet weekly as a tumour board to agree each plan; you can ask when yours was discussed and what was decided.
- RadiologistNamed in the standard of care for: Very-low / low risk (L1, MS), High risk: induction, Relapsed / refractory.
- SurgeonNamed in the standard of care for: High-risk, Very-low / low risk (L1, MS), Intermediate risk, High risk: local control.
- Medical oncologistNamed in the standard of care for: High-risk, Very-low / low risk (L1, MS), Intermediate risk, High risk: induction and 5 more.
- Clinical oncologist (radiotherapy)Named in the standard of care for: High risk: induction, High risk: local control, Relapsed / refractory.
- Transplant and cell therapy teamNamed in the standard of care for: High-risk, High risk: consolidation, Relapsed / refractory.
- Palliative and supportive care teamNamed in the standard of care for: Intermediate risk, High risk: induction, Relapsed / refractory, Survivorship.
A second opinion from a centre that treats many similar cases is normal, not rude; the standard of care tells you what to compare it against.
Each row is a setting from the standard of care, in the order it usually arises. Not all will apply to you; your stage and biomarkers decide which do. The guideline grade, where recorded, says how strong the evidence is.

Any stage
- Are there clinical trials I could join, for example of Armoured, logic-gated & next-gen CARs, COG ANBL1531, 131I-MIBG (iobenguane I-131) therapy, Lorlatinib?Trials are how the next standard of care is set; asking early keeps options open.

- What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?Supportive care improves quality of life and helps patients complete treatment.
- I read that “Relapsed high-risk disease”. How does that affect my plan?Open problems are where trials and second opinions matter most.
- I read that “Long-term toxicity of intensive therapy”. How does that affect my plan?Open problems are where trials and second opinions matter most.
Trials open now for this cancer in OnCo, largest phase first. Joining a trial is a decision like any other: ask what the comparison arm is, whether a placebo is used, and what happens if you leave. The cancer page searches ClinicalTrials.gov live for more.

- MYCN amplification: Extra copies of the MYCN oncogene, found in about 20% of neuroblastomas, mark the most aggressive disease and define high risk at any age.
- INRG staging and risk groups: INRG staging is the international system that sorts neuroblastoma into four risk groups, from the lowest (often observed, sometimes regressing on its own) to high risk (about half of patients), using age under 18 months, spread, MYCN amplification, 11q status, ploidy and histology.

- RACE for Children Act: A US law that makes drug companies test new targeted cancer drugs in children whenever the drug's target matters in a childhood cancer, instead of letting them skip children because their cancers are rare.
- Autologous stem cell transplant (ASCT): High-dose chemotherapy (melphalan in myeloma, BEAM in lymphoma) that would permanently destroy the bone marrow, made survivable by giving the patient back their own previously collected stem cells, which engraft in 10-14 days.
- Cytokine release syndrome (CRS): A flood of inflammatory signals when immune cells are activated en masse, causing fever, low blood pressure, and sometimes organ failure.
