Saved in this browserMy questions
21 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 Tumour mutational burden, Perineural and lymphovascular invasion, Depth of invasion and differentiation grade, Immunosuppression status, PD-L1 expression), 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 (high-risk resectable disease), which of the standard options do you recommend and why?
- 6.Am I a candidate for Cemiplimab, and what side effects should I expect?
- 7.For my situation (adjuvant after surgery and radiotherapy), which of the standard options do you recommend and why?
- 8.Am I a candidate for Cemiplimab, and what side effects should I expect?
- 9.For my situation (locally advanced or metastatic, first line), which of the standard options do you recommend and why?
- 10.Am I a candidate for Cemiplimab, Pembrolizumab, Cosibelimab, and what side effects should I expect?
- 11.How do the results of EMPOWER-CSCC-1 and KEYNOTE-629 apply to someone like me?
- 12.For my situation (immunotherapy-ineligible or refractory), which of the standard options do you recommend and why?
- 13.Am I a candidate for Cetuximab, Carboplatin, Vusolimogene oderparepvec, and what side effects should I expect?
- 14.How do the results of Study Evaluating Cemiplimab Alone and Combined With RP1 in Treating Advanced Squamous Skin Cancer and An Open-label Study Using ASP-1929 Photoimmunotherapy in Combination With Anti-PD1 Therapy in EGFR Expressing Advanced Solid Tumors apply to someone like me?
- 15.For my situation (transplant recipients), which of the standard options do you recommend and why?
- 16.Am I a candidate for Everolimus, Cemiplimab, and what side effects should I expect?
- 17.Are there clinical trials I could join, for example of Study Evaluating Cemiplimab Alone and Combined With RP1 in Treating Advanced Squamous Skin Cancer, An Open-label Study Using ASP-1929 Photoimmunotherapy in Combination With Anti-PD1 Therapy in EGFR Expressing Advanced Solid Tumors, Study of Intralesional Cemiplimab in Adult Patients With Early Stage Cutaneous Squamous Cell Carcinoma, HMBD-001?
- 18.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 19.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 20.I read that “Transplant recipients, who have the highest incidence, cannot safely receive the most effective drugs”. How does that affect my plan?
- 21.I read that “About half of patients do not respond to PD-1 blockade and there is no approved second-line therapy”. 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.
- Tumour mutational burden (TMB): How many mutations a tumour has.
- Pathologic complete response (pCR): No invasive cancer left in the breast and lymph nodes when the surgeon removes the tissue after pre-surgery treatment.
- Neoadjuvant / adjuvant / perioperative: Neoadjuvant therapy is treatment given before surgery, adjuvant therapy is treatment given after it, and perioperative therapy is both.
Tests and results to bring
Biomarker results to ask for: Tumour mutational burden (very high; ultraviolet signature), Perineural and lymphovascular invasion, Depth of invasion and differentiation grade, Immunosuppression status (transplant, chronic lymphocytic leukaemia, HIV), PD-L1 expression (not required for treatment), Pathological response after neoadjuvant immunotherapy.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Adjuvant after surgery and radiotherapy: Cemiplimab for high-risk disease (C-POST, 2025). (Cemiplimab)
- High-risk resectable disease: Excision with margin control or Mohs surgery, nodal evaluation, and postoperative radiotherapy for perineural invasion, positive margins or nodal disease; neoadjuvant cemiplimab to shrink large tumours before surgery. (Mohs surgery, IMRT / IGRT (modern external beam), Cemiplimab, Sentinel lymph node biopsy)
- Locally advanced or metastatic, first line: Cemiplimab (EMPOWER-CSCC-1), pembrolizumab (KEYNOTE-629) or cosibelimab; radiotherapy for symptomatic sites. (EMPOWER-CSCC-1, KEYNOTE-629, Cemiplimab, Pembrolizumab, Cosibelimab, IMRT / IGRT (modern external beam))
- Transplant recipients: Reduce immunosuppression and switch to sirolimus or everolimus where possible; PD-1 blockade only after weighing graft rejection risk; surgery and radiotherapy preferred. (Everolimus, Cemiplimab)
- Immunotherapy-ineligible or refractory: Cetuximab with or without radiotherapy, platinum-based chemotherapy, capecitabine; clinical trials of RP1 with cemiplimab or photoimmunotherapy. (Cetuximab, Carboplatin, Study Evaluating Cemiplimab Alone and Combined With RP1 in Treating Advanced Squamous Skin Cancer, An Open-label Study Using ASP-1929 Photoimmunotherapy in Combination With Anti-PD1 Therapy in EGFR Expressing Advanced Solid Tumors, Vusolimogene oderparepvec)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
