Saved in this browserMy questions
15 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 Calcitonin and CEA, Germline RET testing in every patient, Somatic RET M918T, RAS mutations in RET-negative tumours), 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 (hereditary ret carriers), 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 (advanced ret-mutant disease), which of the standard options do you recommend and why?
- 8.Am I a candidate for Selpercatinib, Pralsetinib, and what side effects should I expect?
- 9.For my situation (advanced ret-negative disease), which of the standard options do you recommend and why?
- 10.Am I a candidate for Cabozantinib, Vandetanib, and what side effects should I expect?
- 11.Are there clinical trials I could join, for example of Selpercatinib?
- 12.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 13.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 14.I read that “No cure once the disease has spread beyond the neck”. How does that affect my plan?
- 15.I read that “Resistance mutations to RET inhibitors (G810) are emerging”. How does that affect my plan?
Tests and results to bring
Biomarker results to ask for: Calcitonin and CEA (diagnosis, follow-up and doubling time), Germline RET testing in every patient, Somatic RET M918T, RAS mutations in RET-negative tumours.
Scans and tests linked to this cancer: Serum tumour markers: proper use and misuse, Thyroglobulin, calcitonin and CEA in thyroid cancer follow-up.
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: Total thyroidectomy with central compartment dissection, lateral dissection when nodes are involved; no radioactive iodine; levothyroxine replacement only. (Thyroid cancer)
- Hereditary RET carriers: Prophylactic total thyroidectomy in childhood, timed by the RET codon risk category (before age one in MEN2B). (RET, Multiple endocrine neoplasia syndromes (MEN1, MEN2, MEN4))
- Advanced RET-mutant disease: Selpercatinib first line (LIBRETTO-531 beat cabozantinib and vandetanib); pralsetinib as an alternative. (Selpercatinib, Pralsetinib, RET)
- Advanced RET-negative disease: Cabozantinib or vandetanib; external radiotherapy for local control; somatostatin analogues for diarrhoea from calcitonin. (Cabozantinib, Vandetanib)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
