Saved in this browserMy questions
26 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 EGFR mutation by tissue or plasma sequencing before first-line therapy, T790M and C797S at progression, MET amplification at progression, Circulating tumour DNA clearance during treatment, Repeat biopsy at progression for small-cell transformation), 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 (exon 19 deletion or l858r)), which of the standard options do you recommend and why?

- 21.Am I a candidate for Osimertinib, and what side effects should I expect?
- 22.Are there clinical trials I could join, for example of Savolitinib, Osimertinib Plus Savolitinib in EGFRm+/MET+ NSCLC Following Prior Osimertinib, Patritumab deruxtecan, HERTHENA-Lung02?
- 23.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 24.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 25.I read that “No head-to-head trial compares the three first-line strategies, and the added toxicity of the combinations falls on every patient for a benefit concentrated in some”. How does that affect my plan?
- 26.I read that “Most resistance to osimertinib has no identifiable mechanism and no targeted option”. How does that affect my plan?
The words I may hear
- EGFR mutation subtypes (exon 19 deletion, L858R, exon 20 insertion, T790M): Lung cancers with a mutated EGFR gene are treated with EGFR pills, but which pill and how well it works depends on exactly where the mutation is.
- EGFR C797S: A mutation that stops osimertinib from binding to EGFR; the main on-target way lung cancers escape it.
- EGFR exon 20 insertion: A rarer EGFR mutation (~2% of lung cancers) that does not respond to standard EGFR pills and needs its own drugs.
- MET amplification (bypass resistance): When lung cancer switches on the MET receptor to bypass a blocked EGFR pill.
- EGFR exon 19 deletion & L858R: Exon 19 deletion and L858R are the two common EGFR mutations, together ~85% of EGFR-mutant lung cancer, and both respond to EGFR pills.
- Leptomeningeal disease: Cancer cells spreading in the fluid and membranes that bathe the brain and spinal cord, rather than as a solid lump.
- Lobectomy: Removing one lobe of the lung (the right lung has three, the left two).
- Driver mutation: One of the few mutations in a tumour that actually causes it to grow.
- Oncogene addiction: When a cancer depends so completely on one mutated gene that blocking it collapses the tumour.
- Tyrosine kinase inhibitor (TKI): Pills that block the on-switch enzyme (a kinase) that a particular cancer depends on: imatinib for CML, osimertinib for EGFR lung cancer, ibrutinib for CLL.
Tests and results to bring
Biomarker results to ask for: EGFR mutation by tissue or plasma sequencing before first-line therapy (exon 19 deletion, L858R, exon 20 insertion, uncommon), T790M and C797S at progression, MET amplification at progression (fluorescence in situ hybridisation or sequencing), Circulating tumour DNA clearance during treatment (under study), Repeat biopsy at progression for small-cell transformation, PD-L1 (of limited use; checkpoint inhibitors work poorly).
Scans and tests linked to this cancer: Comprehensive genomic profiling, Liquid biopsy (ctDNA), MRD / molecular residual disease testing.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Unresectable stage III: Concurrent platinum chemoradiation followed by osimertinib until progression (LAURA) rather than durvalumab. (Osimertinib, LAURA, Chemoradiation (chemoradiotherapy, CRT), IMRT / IGRT (modern external beam))
- Advanced, first line (exon 19 deletion or L858R): Osimertinib alone (FLAURA), osimertinib plus platinum-pemetrexed (FLAURA2) for patients with high burden or brain metastases who can take chemotherapy, or amivantamab plus lazertinib (MARIPOSA) with prophylaxis against rash and clots. (Osimertinib, FLAURA, FLAURA2, Amivantamab, Lazertinib, Amivantamab + lazertinib (first-line EGFR NSCLC), MARIPOSA, EGFR exon 19 deletion & L858R)
- Advanced, exon 20 insertion: Amivantamab plus carboplatin-pemetrexed first line (PAPILLON); sunvozertinib after platinum chemotherapy. (Amivantamab, A Study of Combination Amivantamab and Carboplatin-Pemetrexed Therapy, Compared With Carboplatin-Pemetrexed, in Participants With Advanced or Metastatic Non-Small Cell Lung Cancer Characterized by Epidermal Growth Factor Receptor (EGFR) Exon 20 Insertions, Sunvozertinib, Assessing an Oral EGFR Inhibitor, Sunvozertinib in Patients Who Have Advanced Non-small Cell Lung Cancer With EGFR or HER2 Mutation (WU-KONG1), EGFR exon 20 insertion, Carboplatin, Pemetrexed)
- Advanced, after osimertinib: Biopsy or plasma test for the mechanism: osimertinib plus savolitinib for MET amplification; otherwise amivantamab plus platinum chemotherapy (MARIPOSA-2), platinum-pemetrexed, or datopotamab deruxtecan after chemotherapy; platinum-etoposide for small-cell transformation. (Amivantamab, A Study of Amivantamab and Lazertinib in Combination With Platinum-Based Chemotherapy Compared With Platinum-Based Chemotherapy in Patients With Epidermal Growth Factor Receptor (EGFR)-Mutated Locally Advanced or Metastatic Non- Small Cell Lung Cancer After Osimertinib Failure, Savolitinib, Osimertinib Plus Savolitinib in EGFRm+/MET+ NSCLC Following Prior Osimertinib, Datopotamab deruxtecan, TROPION-Lung05, MET amplification (bypass resistance), EGFR C797S, Histologic transformation, Platinum + etoposide (EP / CE))
- Resected stage IB to IIIA: Surgery, adjuvant platinum chemotherapy where indicated, then three years of osimertinib (ADAURA). (Osimertinib, ADAURA, Lobectomy, Neoadjuvant / adjuvant / perioperative)
- Brain and leptomeningeal metastases: Osimertinib has high brain penetration and is preferred; stereotactic radiosurgery for symptomatic or large lesions; high-dose osimertinib for leptomeningeal disease. (Osimertinib, Stereotactic radiosurgery (Gamma Knife, CyberKnife, linac SRS), Brain metastases (intracranial disease), Leptomeningeal disease)
