Saved in this browserMy questions
19 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 Ki-67 above 20 percentwith well-differentiated morphology, Retained p53 and Rb by immunohistochemistry, Somatostatin receptor PET, usually positive, with FDG PET for dual-tracer assessment, Chromogranin A, MEN1, DAXX and ATRX alterations), 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 (advanced, somatostatin receptor-positive), which of the standard options do you recommend and why?
- 7.Am I a candidate for Lutetium-177 dotatate, Somatostatin analogues (octreotide, lanreotide), and what side effects should I expect?
- 8.How do the results of Study to Evaluate the Efficacy and Safety of Lutathera in Patients With Grade 2 and Grade 3 Advanced GEP-NET apply to someone like me?
- 9.For my situation (advanced, shrinkage needed or receptor-negative), which of the standard options do you recommend and why?
- 10.Am I a candidate for Capecitabine + temozolomide (CAPTEM), Everolimus, Sunitinib or related drugs, and what side effects should I expect?
- 11.For my situation (trials), which of the standard options do you recommend and why?
- 12.Am I a candidate for 177Lu-edotreotide, and what side effects should I expect?
- 13.How do the results of Lutetium 177Lu-Edotreotide Versus Best Standard of Care in Well-differentiated Aggressive Grade-2 and Grade-3 GastroEnteroPancreatic NeuroEndocrine Tumors (GEP-NETs) - COMPOSE apply to someone like me?
- 14.For my situation (limited disease), which of the standard options do you recommend and why?
- 15.Are there clinical trials I could join, for example of Lutetium 177Lu-Edotreotide Versus Best Standard of Care in Well-differentiated Aggressive Grade-2 and Grade-3 GastroEnteroPancreatic NeuroEndocrine Tumors (GEP-NETs) - COMPOSE, 177Lu-edotreotide, Lutetium-177 dotatate, Capecitabine + temozolomide (CAPTEM)?
- 16.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 17.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 18.I read that “The Ki-67 boundary between grade 3 tumour and carcinoma is not sharp, and some cases can only be settled by molecular testing”. How does that affect my plan?
- 19.I read that “No trial has been run in grade 3 tumours alone; NETTER-2 and COMPOSE mix them with grade 2”. How does that affect my plan?
The words I may hear
- PRRT (peptide receptor radionuclide therapy): A radioactive drug for neuroendocrine tumours: a small peptide that homes to the somatostatin receptor on the tumour cells carries lutetium-177, which irradiates them from within.
- Tumour differentiation (well / moderately / poorly differentiated): How much the cancer cells still resemble the normal tissue they came from.
- Chromogranin A: Chromogranin A is a protein released by neuroendocrine cells and measured in blood to follow tumour burden; it is unreliable because acid-reducing drugs and kidney disease also raise it.
- Neuroendocrine tumour grade (Ki-67) and WHO classification: How fast the tumour cells are dividing, measured by Ki-67 staining, separates slow-growing neuroendocrine tumours from aggressive neuroendocrine carcinomas and decides the treatment.
- Liver-directed therapy (TACE, TARE, HAI, ablation): The set of treatments aimed only at tumours in the liver, delivered through its artery or by needle, used when the liver is the main or only site of disease: chemoembolisation, radioactive beads, ablation and infusion pumps.
- Hepatectomy (liver resection): Cutting out the part of the liver containing tumour.
Tests and results to bring
Diagnosis: Morphology, Ki-67 and p53 or Rb immunohistochemistry to separate grade 3 tumour from carcinoma; somatostatin receptor and FDG PET together.
Biomarker results to ask for: Ki-67 above 20 percent (usually 20 to 55 percent) with well-differentiated morphology, Retained p53 and Rb by immunohistochemistry (abnormal in carcinoma), Somatostatin receptor PET, usually positive, with FDG PET for dual-tracer assessment, Chromogranin A (monitoring), MEN1, DAXX and ATRX alterations (tumour lineage, research), MGMT status (CAPTEM response, investigational).
Scans and tests linked to this cancer: PET (positron emission tomography), Somatostatin receptor PET (68Ga/64Cu-DOTATATE).
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Limited disease: Resection and liver-directed therapy as for other well-differentiated tumours. (Hepatectomy (liver resection), Thermal ablation (RFA, microwave, cryo), Transarterial chemoembolisation (TACE), Liver-directed therapy (TACE, TARE, HAI, ablation))
- Advanced, somatostatin receptor-positive: Lutetium-177 dotatate first line for Ki-67 up to 55 percent (NETTER-2); somatostatin analogue alongside. (Lutetium-177 dotatate, Study to Evaluate the Efficacy and Safety of Lutathera in Patients With Grade 2 and Grade 3 Advanced GEP-NET, Peptide receptor radionuclide therapy (PRRT), Somatostatin analogues (octreotide, lanreotide))
- Advanced, shrinkage needed or receptor-negative: Capecitabine with temozolomide; everolimus or sunitinib for pancreatic tumours; platinum-etoposide for carcinoma-like tempo or Ki-67 near 55 percent. (Capecitabine + temozolomide (CAPTEM), Everolimus, Sunitinib, Platinum + etoposide (EP / CE))
- Trials: COMPOSE: 177Lu-edotreotide against CAPTEM, everolimus or FOLFOX in aggressive grade 2 and grade 3 gastroenteropancreatic tumours. (Lutetium 177Lu-Edotreotide Versus Best Standard of Care in Well-differentiated Aggressive Grade-2 and Grade-3 GastroEnteroPancreatic NeuroEndocrine Tumors (GEP-NETs) - COMPOSE, 177Lu-edotreotide)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
