What I know, what is unclear, changes to discuss
Saved in this browserMy questions
16 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 H3K27 trimethylation on immunohistochemistry, NF1, CDKN2A, SUZ12 or EED alterations, TP53 loss, FDG-PET uptake in neurofibromas, Germline NF1 status), 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 (localised), which of the standard options do you recommend and why?
- 6.Am I a candidate for Doxorubicin, Ifosfamide, and what side effects should I expect?
- 7.For my situation (advanced), which of the standard options do you recommend and why?
- 8.Am I a candidate for Doxorubicin, Ifosfamide, Etoposide, and what side effects should I expect?
- 9.How do the results of EORTC 62012 apply to someone like me?
- 10.For my situation (neurofibromatosis type 1 surveillance), which of the standard options do you recommend and why?
- 11.Am I a candidate for Selumetinib, Mirdametinib, and what side effects should I expect?
- 12.Are there clinical trials I could join, for example of Selumetinib, Mirdametinib, MEK1/2, RAS / RAF / MEK / ERK (MAPK)?
- 13.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 14.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 15.I read that “Metastasis is common even after complete local treatment”. How does that affect my plan?
- 16.I read that “Chemotherapy works less well in the NF1-associated tumours that make up half of cases”. How does that affect my plan?
Tests and results to bring
Biomarker results to ask for: Loss of H3K27 trimethylation on immunohistochemistry (PRC2 loss), NF1, CDKN2A, SUZ12 or EED alterations, TP53 loss (high grade), FDG-PET uptake in neurofibromas (transformation), Germline NF1 status.
Scans and tests linked to this cancer: MRI, PET/CT.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Localised: Wide resection with preoperative or postoperative radiotherapy; nerve sacrifice and reconstruction as needed; consider neoadjuvant or adjuvant anthracycline-ifosfamide for large high-grade tumours. (Limb-salvage surgery and endoprosthetic reconstruction, IMRT / IGRT (modern external beam), Doxorubicin, Ifosfamide)
- Advanced: Doxorubicin plus ifosfamide (EORTC 62012), then ifosfamide-etoposide or trials; response rates lower in NF1-associated tumours. (Doxorubicin, Ifosfamide, EORTC 62012, Etoposide)
- Neurofibromatosis type 1 surveillance: Whole-body MRI and FDG-PET for growing or painful plexiform neurofibromas; biopsy of atypical lesions; MEK inhibitors for symptomatic plexiform neurofibromas. (MRI, PET/CT, Selumetinib, Mirdametinib)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
