Saved in this browserMy questions
16 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 and ulceration, BRAF V600 mutation, NRAS mutation, KIT mutation or amplification, CCND1, CDK4 and TERT amplification), 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), which of the standard options do you recommend and why?
- 6.For my situation (localised disease), which of the standard options do you recommend and why?
- 7.For my situation (resected stage iii), which of the standard options do you recommend and why?
- 8.Am I a candidate for Nivolumab, Pembrolizumab, Dabrafenib + trametinib, and what side effects should I expect?
- 9.How do the results of NADINA apply to someone like me?
- 10.For my situation (advanced disease), which of the standard options do you recommend and why?
- 11.Am I a candidate for Nivolumab, Ipilimumab, Pembrolizumab or related drugs, and what side effects should I expect?
- 12.Are there clinical trials I could join, for example of Tunlametinib, Comparing Tunlametinib Capsules and Combination Chemotherapy in Advanced NRAS-mutant Melanoma, Palbociclib, Imatinib?
- 13.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 14.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 15.I read that “Late diagnosis remains the main cause of poor outcomes and awareness in people with darker skin is low”. How does that affect my plan?
- 16.I read that “No trial has been designed for acral melanoma alone outside East Asia”. 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.
Tests and results to bring
Diagnosis: Dermoscopy of the parallel ridge pattern and biopsy of any changing pigmented lesion of the palm, sole or nail; nail matrix biopsy for longitudinal melanonychia with Hutchinson sign.
Biomarker results to ask for: Breslow thickness and ulceration, BRAF V600 mutation, NRAS mutation, KIT mutation or amplification, CCND1, CDK4 and TERT amplification (research), Low tumour mutational burden.
Scans and tests linked to this cancer: 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
- Localised disease: Wide local excision with thickness-based margins, distal amputation for subungual disease when needed, sentinel lymph node biopsy for primaries over 0.8 mm. (Wide local excision, Sentinel lymph node biopsy, Breslow thickness)
- Resected stage III: Adjuvant nivolumab or pembrolizumab; dabrafenib-trametinib for BRAF V600-mutant disease; neoadjuvant immunotherapy for macroscopic nodes as in NADINA. (Nivolumab, Pembrolizumab, Dabrafenib + trametinib, NADINA)
- Advanced disease: Nivolumab plus ipilimumab or anti-PD-1 monotherapy; BRAF-MEK inhibitors for BRAF-mutant tumours; imatinib for KIT-mutant tumours; tunlametinib for NRAS-mutant disease in China; trials of CDK4/6 inhibitors. (Nivolumab, Ipilimumab, Pembrolizumab, Dabrafenib + trametinib, Imatinib, Tunlametinib, Palbociclib)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
