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 KRAS G12C by tissue or plasma next-generation sequencing, Co-alterations in TP53, CDKN2A and SMAD4, Acquired KRAS mutations, KRAS amplification or receptor tyrosine kinase bypass at progression, CA 19-9 for response monitoring, Liver enzymes on a G12C inhibitor), 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 (first line), which of the standard options do you recommend and why?
- 6.Am I a candidate for FOLFIRINOX / mFOLFIRINOX, NALIRIFOX (liposomal irinotecan + oxaliplatin + 5-FU/LV), Gemcitabine + nab-paclitaxel, and what side effects should I expect?
- 7.For my situation (after first-line chemotherapy), which of the standard options do you recommend and why?
- 8.Am I a candidate for Daraxonrasib, Sotorasib, Adagrasib, and what side effects should I expect?
- 9.How do the results of RASolute 302 apply to someone like me?
- 10.For my situation (clinical trials), which of the standard options do you recommend and why?
- 11.Am I a candidate for Elironrasib, Olomorasib, Glecirasib, and what side effects should I expect?
- 12.How do the results of Study of Elironrasib and Daraxonrasib as Monotherapies and Combination Therapy in Participants With Advanced KRAS G12C Mutant Solid Tumors and Study of LY3537982 in Cancer Patients With a Specific Genetic Mutation (KRAS G12C) apply to someone like me?
- 13.Are there clinical trials I could join, for example of Elironrasib, Study of Elironrasib and Daraxonrasib as Monotherapies and Combination Therapy in Participants With Advanced KRAS G12C Mutant Solid Tumors, Olomorasib, Study of LY3537982 in Cancer Patients With a Specific Genetic Mutation (KRAS G12C)?
- 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 “Responses to G12C-selective inhibitors are shallower and shorter in the pancreas than in the lung”. How does that affect my plan?
- 17.I read that “Neither sotorasib nor adagrasib has a pancreatic indication, so access depends on off-label use and trials”. How does that affect my plan?
The words I may hear
- Oncogene: A gene that, when over-activated by mutation or extra copies, pushes a cell to grow and divide.
- KRAS mutation subtypes (G12C, G12D, G12V): KRAS, the most commonly mutated cancer gene, comes in flavours named by the exact amino acid change.
- CA 19-9: A sugar molecule shed into the blood by most pancreatic cancers; useful to follow treatment, not to screen.
- Drug resistance (primary and acquired): Why cancer drugs stop working: the tumour either never depended on the target or evolves around the block.
- Driver mutation: One of the few mutations in a tumour that actually causes it to grow.
Tests and results to bring
Biomarker results to ask for: KRAS G12C by tissue or plasma next-generation sequencing (about 1 to 2 percent of pancreatic adenocarcinomas), Co-alterations in TP53, CDKN2A and SMAD4, Acquired KRAS mutations, KRAS amplification or receptor tyrosine kinase bypass at progression, CA 19-9 for response monitoring, Liver enzymes on a G12C inhibitor.
Scans and tests linked to this cancer: Comprehensive genomic profiling, Liquid biopsy (ctDNA).
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- First line: Chemotherapy as for other pancreatic adenocarcinoma: modified FOLFIRINOX, NALIRIFOX or gemcitabine plus nab-paclitaxel; G12C inhibitors are not approved first line. (FOLFIRINOX / mFOLFIRINOX, NALIRIFOX (liposomal irinotecan + oxaliplatin + 5-FU/LV), Gemcitabine + nab-paclitaxel, KRAS mutation subtypes (G12C, G12D, G12V))
- After first-line chemotherapy: Daraxonrasib (RASolute 302, approved for pancreatic cancer irrespective of KRAS subtype); sotorasib or adagrasib as NCCN-listed options on the CodeBreaK 100 and KRYSTAL-1 cohorts. (Daraxonrasib, RASolute 302, Sotorasib, Adagrasib, KRAS & RAS inhibitors)
- Clinical trials: Elironrasib with daraxonrasib, olomorasib, glecirasib and other G12C-selective inhibitors alone or with chemotherapy or EGFR antibodies. (Elironrasib, Study of Elironrasib and Daraxonrasib as Monotherapies and Combination Therapy in Participants With Advanced KRAS G12C Mutant Solid Tumors, Olomorasib, Study of LY3537982 in Cancer Patients With a Specific Genetic Mutation (KRAS G12C), Glecirasib, A Phase II Study Evaluating JAB-21822 Monotherapy in Adult Patients With Pancreatic Cancer and Other Solid Tumors Harboring the KRAS p.G12C Mutation.)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
