Saved in this browserMy questions
23 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 PTCH1 loss or SMO activation, Germline PTCH1 or SUFU, SMO resistance mutations after hedgehog inhibitors, Perineural invasion and bone or orbital involvement on imaging, High ultraviolet-signature tumour mutational burden), 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 (locally advanced, first line), which of the standard options do you recommend and why?
- 6.Am I a candidate for Vismodegib, Sonidegib, and what side effects should I expect?
- 7.How do the results of ERIVANCE BCC and BOLT apply to someone like me?
- 8.For my situation (neoadjuvant), which of the standard options do you recommend and why?
- 9.Am I a candidate for Vismodegib, and what side effects should I expect?
- 10.For my situation (after hedgehog inhibitor failure or intolerance), which of the standard options do you recommend and why?
- 11.Am I a candidate for Cemiplimab, and what side effects should I expect?
- 12.How do the results of Clinical Trial to Evaluate BO-112 in Patients With Basal Cell Carcinoma (BCC) and Study to Investigate the Efficacy and Safety of RP1 in Adult Patients With Organ Transplants and Advanced Skin Malignancies apply to someone like me?
- 13.For my situation (metastatic disease), which of the standard options do you recommend and why?
- 14.Am I a candidate for Vismodegib, Sonidegib, Cemiplimab, and what side effects should I expect?
- 15.For my situation (radiotherapy and local options), which of the standard options do you recommend and why?
- 16.For my situation (gorlin syndrome), which of the standard options do you recommend and why?
- 17.Am I a candidate for Vismodegib, and what side effects should I expect?
- 18.How do the results of Efficacy and Safety of Patidegib Gel 2% for Preventing Basal Cell Carcinomas on the Face of Adults With Gorlin Syndrome apply to someone like me?
- 19.Are there clinical trials I could join, for example of Cemiplimab, To Assess the Safety and Efficacy of SP-002 with Vismodegib for the Treatment of Locally Advanced Basal Cell Carcinoma, Clinical Trial to Evaluate BO-112 in Patients With Basal Cell Carcinoma (BCC), Efficacy and Safety of Patidegib Gel 2% for Preventing Basal Cell Carcinomas on the Face of Adults With Gorlin Syndrome?
- 20.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 21.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 22.I read that “Hedgehog inhibitor side effects lead many patients to stop before the tumour is controlled”. How does that affect my plan?
- 23.I read that “Only about a third of patients respond to cemiplimab after hedgehog inhibitor failure and there is no third line”. How does that affect my plan?
The words I may hear
- Mohs surgery: Skin cancer surgery in which the tumour is removed in thin layers, each checked under the microscope on the spot, until the edges are clear; it spares the most normal skin.
Tests and results to bring
Biomarker results to ask for: PTCH1 loss or SMO activation (nearly universal; testing not needed for treatment), Germline PTCH1 or SUFU (Gorlin syndrome), SMO resistance mutations after hedgehog inhibitors (research), Perineural invasion and bone or orbital involvement on imaging, High ultraviolet-signature tumour mutational burden.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Neoadjuvant: Vismodegib for several months to shrink large facial tumours before surgery and reduce the defect. (Vismodegib, Mohs surgery)
- Locally advanced, first line: Vismodegib (ERIVANCE) or sonidegib (BOLT); intermittent dosing to limit cramps, hair loss and taste loss; surgery or radiotherapy after response where feasible. (ERIVANCE BCC, BOLT, Vismodegib, Sonidegib, Hedgehog pathway inhibitors)
- Metastatic disease: Vismodegib or sonidegib; cemiplimab after progression; platinum chemotherapy has only case-series support. (Vismodegib, Sonidegib, Cemiplimab)
- Radiotherapy and local options: Radiotherapy for tumours not resectable but still confined; electron beam and superficial radiotherapy for suitable sites; multidisciplinary review of all advanced cases. (IMRT / IGRT (modern external beam), Superficial and orthovoltage radiotherapy for skin cancer, Electron beam therapy systems (linac electrons, total skin electron units, mobile electron IORT))
- Gorlin syndrome: Surveillance and surgery, avoidance of radiotherapy, hedgehog inhibitors for multiple advanced tumours, topical patidegib in trials. (Vismodegib, Efficacy and Safety of Patidegib Gel 2% for Preventing Basal Cell Carcinomas on the Face of Adults With Gorlin Syndrome)
- After hedgehog inhibitor failure or intolerance: Cemiplimab (approved 2021); clinical trials of intratumoural agents and immunotherapy combinations. (Cemiplimab, Clinical Trial to Evaluate BO-112 in Patients With Basal Cell Carcinoma (BCC), Study to Investigate the Efficacy and Safety of RP1 in Adult Patients With Organ Transplants and Advanced Skin Malignancies)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
