Saved in this browserMy questions
14 on the sheet- 1.What is my exact diagnosis, stage, and grade, and which tests established them?
- 2.Which biomarkers have been tested on my tumour (for example Loss of SMARCB1nuclear staining by immunohistochemistry, SMARCB1 or SMARCA4 sequencing, somatic and germline, Methylation subgroup, Metastatic stage on MRI and cerebrospinal-fluid cytology, Age), and what were the results?
- 3.Which subtype is my cancer, and does that change the recommended treatment?
- 4.Is germline (inherited) genetic testing recommended for me or my family?
- 5.For my situation (newly diagnosed, any age), which of the standard options do you recommend and why?
- 6.Am I a candidate for Methotrexate, Cyclophosphamide, Cisplatin or related drugs, and what side effects should I expect?
- 7.For my situation (germline smarcb1 or smarca4 alteration), which of the standard options do you recommend and why?
- 8.For my situation (relapsed or refractory), which of the standard options do you recommend and why?
- 9.Am I a candidate for Tazemetostat, and what side effects should I expect?
- 10.Are there clinical trials I could join, for example of DNA methylation profiling, Proton therapy, NCI-COG Pediatric MATCH (APEC1621)?
- 11.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 12.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 13.I read that “Infants too young for radiotherapy and children with metastatic or ATRT-MYC disease still do poorly; SIOPE ATRT01 and COG successors are testing intensified and subgroup-directed therapy”. How does that affect my plan?
- 14.I read that “Long-term neurocognitive and endocrine cost of intensive therapy in the first years of life; proton therapy and radiation-sparing arms aim to reduce it”. How does that affect my plan?
The words I may hear
- Late effects and survivorship toxicity: Health problems appearing months or decades after treatment ends: heart damage, infertility, second cancers, lymphoedema, dry mouth, memory problems, weak bones.
- Hereditary cancer syndromes: About 5-10% of cancers arise from an inherited gene fault.
Tests and results to bring
Newly diagnosed, any age: Maximal safe resection followed by an intensive multimodal protocol: ACNS0333-style induction, high-dose chemotherapy with autologous stem-cell rescue, and age-adapted focal radiotherapy; or the EU-RHAB regimen with intraventricular methotrexate. Enrolment in SIOPE ATRT01 or a COG successor where available.
Biomarker results to ask for: Loss of SMARCB1 (INI1) nuclear staining by immunohistochemistry, SMARCB1 or SMARCA4 sequencing, somatic and germline, Methylation subgroup (TYR, SHH, MYC), Metastatic stage on MRI and cerebrospinal-fluid cytology, Age (radiotherapy eligibility), Extent of resection.
Scans and tests linked to this cancer: Germline (hereditary) testing, DNA methylation profiling.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Germline SMARCB1 or SMARCA4 alteration: Genetic counselling and testing of parents and siblings; surveillance imaging for synchronous or second rhabdoid tumours in the kidney and soft tissue. (Germline (hereditary) testing)
- Relapsed or refractory: No standard; EZH2 inhibition with tazemetostat was explored in trials and compassionate use until the drug was withdrawn from all markets in March 2026; aurora kinase A inhibition, re-irradiation where feasible; early palliative care. (Tazemetostat, Early integrated palliative care)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
