Saved in this browserMy questions
20 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 PD-L1 combined positive score, Epstein-Barr virus in situ hybridisation, Microsatellite instability and mismatch repair, HER2, Claudin 18.2), 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 (advanced, first line, cps 5 or above), which of the standard options do you recommend and why?
- 6.Am I a candidate for Nivolumab, Pembrolizumab, FOLFOX (5-FU, leucovorin, oxaliplatin) or related drugs, and what side effects should I expect?
- 7.How do the results of CheckMate 649 and KEYNOTE-859 apply to someone like me?
- 8.For my situation (advanced, first line, cps 1 to 4), which of the standard options do you recommend and why?
- 9.Am I a candidate for Nivolumab, Pembrolizumab, Zolbetuximab, and what side effects should I expect?
- 10.For my situation (resectable stage ii to iii), which of the standard options do you recommend and why?
- 11.Am I a candidate for Durvalumab, FLOT (5-FU, leucovorin, oxaliplatin, docetaxel), and what side effects should I expect?
- 12.How do the results of MATTERHORN apply to someone like me?
- 13.For my situation (second line), which of the standard options do you recommend and why?
- 14.Am I a candidate for Ramucirumab, Paclitaxel / nab-paclitaxel, and what side effects should I expect?
- 15.How do the results of RAINBOW apply to someone like me?
- 16.Are there clinical trials I could join, for example of MATTERHORN, Tislelizumab, Biomarker-directed first-line quadruplets in gastric cancer, Gotistobart?
- 17.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 18.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 19.I read that “Two assays with different thresholds leave patients near the cut-off in an uncertain position”. How does that affect my plan?
- 20.I read that “Most patients still progress within a year on chemo-immunotherapy”. How does that affect my plan?
The words I may hear
- Combined positive score (CPS): A PD-L1 score that counts stained tumour cells and immune cells together.
Tests and results to bring
Biomarker results to ask for: PD-L1 combined positive score (28-8 or 22C3 assay), Epstein-Barr virus in situ hybridisation, Microsatellite instability and mismatch repair (overlapping responders), HER2 (must be negative for this pathway), Claudin 18.2 (competing first-line target).
Scans and tests linked to this cancer: Companion diagnostics.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Resectable stage II to III: Perioperative FLOT with durvalumab (MATTERHORN), given irrespective of PD-L1 score. (MATTERHORN, Durvalumab, FLOT (5-FU, leucovorin, oxaliplatin, docetaxel))
- Advanced, first line, CPS 5 or above: Nivolumab with FOLFOX or CAPOX (CheckMate 649) or pembrolizumab with platinum-fluoropyrimidine chemotherapy (KEYNOTE-859). (CheckMate 649, KEYNOTE-859, Nivolumab, Pembrolizumab, FOLFOX (5-FU, leucovorin, oxaliplatin), CAPOX (capecitabine, oxaliplatin), PD-L1, Combined positive score (CPS))
- Advanced, first line, CPS 1 to 4: PD-1 antibody with chemotherapy is permitted in the United States and offered with a smaller expected gain; chemotherapy alone or zolbetuximab where claudin 18.2 is positive. (Nivolumab, Pembrolizumab, Zolbetuximab, Combined positive score (CPS))
- Second line: Ramucirumab with paclitaxel (RAINBOW); no established role for continued PD-1 blockade. (RAINBOW, Ramucirumab, Paclitaxel / nab-paclitaxel)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
