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 Histologic subtype and high-risk location, PTCH1 / SMO / SUFU alterations, Perineural invasion, Germline PTCH1), 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 (low-risk), which of the standard options do you recommend and why?
- 6.Am I a candidate for Fluorouracil (5-FU), and what side effects should I expect?
- 7.For my situation (high-risk or recurrent), which of the standard options do you recommend and why?
- 8.For my situation (locally advanced or metastatic), which of the standard options do you recommend and why?
- 9.Am I a candidate for Vismodegib, Sonidegib, Cemiplimab, and what side effects should I expect?
- 10.Are there clinical trials I could join, for example of Cemiplimab, Vismodegib?
- 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 “Hedgehog-inhibitor tolerability leads most patients to stop within a year”. How does that affect my plan?
- 14.I read that “Resistance via SMO mutations has no approved next-in-class agent”. How does that affect my plan?
The words I may hear
- Cancer stem cell theory and phenotypic plasticity: The idea that a tumour is organised like a tissue, with a small pool of stem-like cells that renew it and a bulk that cannot, so killing the bulk shrinks the tumour but the stem-like cells regrow it.
- Immune-related adverse events (irAEs): Immune-related adverse events (irAEs) are the autoimmune side effects of checkpoint inhibitors: colitis, thyroid problems, rash, hepatitis, pneumonitis.
Tests and results to bring
Biomarker results to ask for: Histologic subtype and high-risk location (H-zone of face), PTCH1 / SMO / SUFU alterations (research; SMO mutations predict hedgehog-inhibitor resistance), Perineural invasion, Germline PTCH1 (Gorlin).
Scans and tests linked to this cancer: Confocal microscopy and optical coherence tomography for skin (VivaScope, VivoSight, deepLive), Dermoscopy, total-body photography & AI skin analysis, Skin cancer screening (visual skin examination).
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- High-risk or recurrent: Mohs micrographic surgery or excision with complete margin assessment; radiotherapy if surgery not feasible. (IMRT / IGRT (modern external beam))
- Locally advanced or metastatic: Vismodegib or sonidegib; cemiplimab after hedgehog-inhibitor failure or intolerance; multidisciplinary review for surgery/radiotherapy after response. (Vismodegib, Sonidegib, Cemiplimab)
- Low-risk: Standard excision with 4 mm margin, curettage and electrodesiccation, or topical imiquimod / 5-FU / photodynamic therapy for superficial lesions. (Fluorouracil (5-FU))
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
