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 CTNNB1 mutation type, Germline APC testing when intra-abdominal or multifocal, Nuclear beta-catenin immunostaining, MRI T2 signal, Symptom and pain scores), 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, asymptomatic or minimally symptomatic), which of the standard options do you recommend and why?
- 6.For my situation (progressive or symptomatic disease), which of the standard options do you recommend and why?
- 7.Am I a candidate for Nirogacestat, Sorafenib, Methotrexate, and what side effects should I expect?
- 8.How do the results of DeFi apply to someone like me?
- 9.For my situation (surgery), which of the standard options do you recommend and why?
- 10.Are there clinical trials I could join, for example of Nirogacestat, Intermittent or stop-and-restart nirogacestat in desmoid tumours, DeFi, Varegacestat?
- 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 “Ovarian toxicity of gamma-secretase inhibitors in young women: dose interruption and intermittent schedules are being explored”. How does that affect my plan?
- 14.I read that “Optimal treatment duration and whether responses persist after stopping nirogacestat”. How does that affect my plan?
The words I may hear
- Rare cancers: Rare cancers are those with fewer than about 6 new cases per 100,000 people per year.
Tests and results to bring
Newly diagnosed, asymptomatic or minimally symptomatic: Active surveillance with MRI at 1 to 2 months, then every 3 to 6 months; treat only on progression or symptoms.
Biomarker results to ask for: CTNNB1 mutation type (S45F associated with higher recurrence), Germline APC testing when intra-abdominal or multifocal, Nuclear beta-catenin immunostaining, MRI T2 signal (hypointense tumours are more likely to be stable or regressing), Symptom and pain scores (treatment triggers).
Scans and tests linked to this cancer: Active surveillance, MRI.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Surgery: Reserved for selected abdominal wall tumours or complications (bowel obstruction, fistula); margins do not reliably predict recurrence. (Limb-salvage surgery and endoprosthetic reconstruction)
- Progressive or symptomatic disease: Nirogacestat (DeFi) or sorafenib (Alliance A091105); alternatives include methotrexate-vinblastine, vinorelbine, anthracycline-based chemotherapy for rapidly progressive disease, and cryoablation for accessible extra-abdominal tumours. (Nirogacestat, Sorafenib, DeFi, Methotrexate)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
