Saved in this browserMy questions
17 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 Breslow thickness, Ulceration of the primary, Sentinel lymph node status, Mitotic rate, BRAF V600 mutation), 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 (diagnosis and surgery), which of the standard options do you recommend and why?
- 6.For my situation (adjuvant, stage iib or iic), which of the standard options do you recommend and why?
- 7.Am I a candidate for Pembrolizumab, Nivolumab, and what side effects should I expect?
- 8.How do the results of KEYNOTE-716 and Effectiveness Study of Nivolumab Compared to Placebo in Prevention of Recurrent Melanoma After Complete Resection of Stage IIB/C Melanoma apply to someone like me?
- 9.For my situation (adjuvant vaccine (emerging)), which of the standard options do you recommend and why?
- 10.Am I a candidate for Intismeran autogene, and what side effects should I expect?
- 11.How do the results of INTerpath-001 (V940-001) apply to someone like me?
- 12.For my situation (surveillance), which of the standard options do you recommend and why?
- 13.Are there clinical trials I could join, for example of INTerpath-001 (V940-001), Intismeran autogene, Adjuvant Encorafenib and Binimetinib in High-risk Stage II Melanoma With a BRAF Mutation., ctDNA-guided adjuvant therapy in stage II-III melanoma?
- 14.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 15.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 16.I read that “Roughly four in five patients would have been cured by surgery alone and cannot yet be told apart from the fifth”. How does that affect my plan?
- 17.I read that “No overall survival benefit has yet been shown for adjuvant therapy in stage II”. How does that affect my plan?
The words I may hear
- Breslow thickness: How deep a melanoma has grown into the skin, in millimetres.
- Ulceration (melanoma): Loss of the skin surface over a melanoma under the microscope; a sign of aggressive biology that raises the stage.
- Wide local excision: Cutting out a tumour together with a measured rim of normal-looking tissue around it, so that microscopic spread at the edge is removed too.
- Circulating tumour DNA (ctDNA): Circulating tumour DNA (ctDNA) consists of fragments of DNA shed by tumour cells into the blood, detectable with sensitive sequencing.
- 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
Diagnosis and surgery: Wide local excision with margins set by thickness and sentinel lymph node biopsy for primaries over 0.8 mm or with ulceration.
Biomarker results to ask for: Breslow thickness, Ulceration of the primary, Sentinel lymph node status (must be negative for stage II), Mitotic rate, BRAF V600 mutation (trial eligibility), Circulating tumour DNA and gene-expression profiles (under study to select who needs adjuvant therapy).
Scans and tests linked to this cancer: Liquid biopsy (ctDNA), 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
- Adjuvant, stage IIB or IIC: One year of pembrolizumab (KEYNOTE-716) or nivolumab (CheckMate 76K), or observation after a shared decision about a modest benefit and immune side effects. (KEYNOTE-716, Effectiveness Study of Nivolumab Compared to Placebo in Prevention of Recurrent Melanoma After Complete Resection of Stage IIB/C Melanoma, Pembrolizumab, Nivolumab)
- Adjuvant vaccine (emerging): Intismeran autogene with pembrolizumab met its endpoints in INTerpath-001, which included stage IIB and IIC; regulatory review pending. (INTerpath-001 (V940-001), Intismeran autogene)
- Surveillance: Skin and nodal examination and, for higher-risk disease, imaging at intervals; patient education on self-examination. (Skin cancer screening (visual skin examination), Dermoscopy, total-body photography & AI skin analysis)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
