Saved in this browserMy questions
18 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 KIAA1549-BRAF fusion, BRAF V600E, NF1 germline status, FGFR1 mutation or fusion, CDKN2A deletion), 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 (resectable tumour), which of the standard options do you recommend and why?
- 6.For my situation (unresectable or progressive, braf v600e), which of the standard options do you recommend and why?
- 7.Am I a candidate for Dabrafenib + trametinib, and what side effects should I expect?
- 8.How do the results of TADPOLE (CDRB436G2201) apply to someone like me?
- 9.For my situation (relapsed or refractory, braf fusion or v600e), which of the standard options do you recommend and why?
- 10.Am I a candidate for Tovorafenib, and what side effects should I expect?
- 11.How do the results of FIREFLY-1 apply to someone like me?
- 12.For my situation (unresectable, no targetable alteration or targeted drug unavailable), which of the standard options do you recommend and why?
- 13.Am I a candidate for Carboplatin, Vincristine, Vinblastine, and what side effects should I expect?
- 14.Are there clinical trials I could join, for example of Tovorafenib, Dabrafenib + trametinib, FIREFLY-1, DNA methylation profiling?
- 15.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 16.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 17.I read that “How long to continue MAPK inhibitors and whether tumours regrow on stopping; intermittent dosing and stop rules are being studied in FIREFLY-2 and the COG selumetinib trials”. How does that affect my plan?
- 18.I read that “Long-term effects of RAF and MEK inhibition on growth plates, skin and heart in children who may take them for years; registries and trial follow-up are collecting these data”. How does that affect my plan?
The words I may hear
- 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.
- 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.
Tests and results to bring
Biomarker results to ask for: KIAA1549-BRAF fusion, BRAF V600E (worse response to chemotherapy, target of BRAF/MEK inhibitors), NF1 germline status, FGFR1 mutation or fusion, CDKN2A deletion (with V600E, marks higher risk), Methylation-based classification, Visual acuity and visual fields in optic pathway glioma.
Scans and tests linked to this cancer: Germline (hereditary) testing, MRI, DNA methylation profiling, Intraoperative MRI and CT.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Resectable tumour: Maximal safe resection; gross total resection is curative in most and no adjuvant therapy is given. Observation for stable residual disease. (MRI)
- Unresectable or progressive, BRAF V600E: Dabrafenib plus trametinib first line (TADPOLE: higher response rate and longer progression-free survival than carboplatin-vincristine; FDA approval March 2023 for patients aged one year and over). (Dabrafenib + trametinib, TADPOLE (CDRB436G2201))
- Unresectable, no targetable alteration or targeted drug unavailable: Carboplatin and vincristine, or weekly vinblastine, to defer radiotherapy; focal conformal or proton radiotherapy is reserved for older children and for progression after systemic options. (Carboplatin, Vincristine, Vinblastine, Proton therapy)
- Relapsed or refractory, BRAF fusion or V600E: Tovorafenib (FIREFLY-1; FDA accelerated approval April 2024 for patients aged six months and over), or a MEK inhibitor such as selumetinib in trials. (Tovorafenib, FIREFLY-1)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
