Saved in this browserMy questions
24 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 Primary tumour type and its driver, Number, size and location of lesions on contrast MRI, Graded prognostic assessment, Cerebrospinal fluid cytology and cell-free DNA for leptomeningeal disease, Distinguishing radionecrosis from progression), 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 (symptomatic oedema), which of the standard options do you recommend and why?
- 6.Am I a candidate for Dexamethasone, and what side effects should I expect?
- 7.For my situation (single large or symptomatic lesion, fit patient), which of the standard options do you recommend and why?
- 8.For my situation (limited number of metastases), which of the standard options do you recommend and why?
- 9.How do the results of Alliance N0574 (NCCTG N0574) apply to someone like me?
- 10.For my situation (many metastases or leptomeningeal spread), which of the standard options do you recommend and why?
- 11.How do the results of NRG CC001 and QUARTZ apply to someone like me?
- 12.For my situation (driver-positive lung cancer, asymptomatic metastases), which of the standard options do you recommend and why?
- 13.Am I a candidate for Osimertinib, Lorlatinib, Alectinib, and what side effects should I expect?
- 14.How do the results of CROWN apply to someone like me?
- 15.For my situation (her2-positive breast cancer), which of the standard options do you recommend and why?
- 16.Am I a candidate for Tucatinib, Trastuzumab deruxtecan, and what side effects should I expect?
- 17.How do the results of HER2CLIMB and DESTINY-Breast12 apply to someone like me?
- 18.For my situation (melanoma), which of the standard options do you recommend and why?
- 19.Am I a candidate for Nivolumab, Ipilimumab, Dabrafenib + trametinib, and what side effects should I expect?
- 20.Are there clinical trials I could join, for example of Trastuzumab deruxtecan, Tucatinib, Lorlatinib, Focused-ultrasound blood-brain barrier opening?
- 21.Would a second opinion at a high-volume centre change anything, and can you help arrange it?
- 22.What supportive care (symptom control, nutrition, exercise, mental health, financial help) is available from the start?
- 23.I read that “Trials still often exclude patients with brain metastases, so drug activity in the brain is learned late”. How does that affect my plan?
- 24.I read that “Leptomeningeal disease has no standard treatment and a survival of months”. How does that affect my plan?
The words I may hear
- Whole-brain radiotherapy (WBRT): Irradiating the entire brain, typically 30 Gy in 10 sessions, when metastases are too numerous or too widespread (leptomeningeal) for focused radiosurgery.
- HER2-positive brain metastases: Up to half of women with metastatic HER2-positive breast cancer develop brain metastases, because antibodies control the body but historically not the brain.
- Leptomeningeal disease: Cancer cells spreading in the fluid and membranes that bathe the brain and spinal cord, rather than as a solid lump.
- Stereotactic radiosurgery (SRS): A single high dose of radiation delivered to a brain tumour or metastasis by beams converging from all sides, so the target gets a destructive dose while the surrounding brain gets little; no scalpel is involved despite the name.
- Blood-brain barrier (BBB): The tight seal around brain blood vessels that keeps most drugs out, one of the two main reasons brain cancer is so hard to treat.
- Brain metastases (intracranial disease): Tumour deposits that have travelled to the brain from a cancer elsewhere, ten times more common than cancers that start in the brain, mostly from lung, breast, melanoma and kidney cancer.
Tests and results to bring
Biomarker results to ask for: Primary tumour type and its driver (EGFR, ALK, HER2, BRAF, PD-L1), Number, size and location of lesions on contrast MRI, Graded prognostic assessment (age, performance status, extracranial disease, lesion count, molecular subtype), Cerebrospinal fluid cytology and cell-free DNA for leptomeningeal disease, Distinguishing radionecrosis from progression (perfusion MRI, amino acid PET).
Scans and tests linked to this cancer: MRI.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Limited number of metastases: Stereotactic radiosurgery alone (Alliance N0574); whole-brain radiotherapy withheld because it worsens cognition without lengthening life. (Stereotactic radiosurgery (Gamma Knife, CyberKnife, linac SRS), Gamma Knife, CyberKnife robotic radiosurgery, Alliance N0574 (NCCTG N0574))
- Symptomatic oedema: Dexamethasone, tapered as quickly as symptoms allow; anticonvulsants only after a seizure. (Dexamethasone)
- Single large or symptomatic lesion, fit patient: Surgical resection followed by radiosurgery to the cavity (N107C) rather than whole-brain radiotherapy. (Stereotactic radiosurgery (Gamma Knife, CyberKnife, linac SRS))
- Many metastases or leptomeningeal spread: Hippocampal-avoidance whole-brain radiotherapy with memantine (NRG CC001) where whole-brain treatment is chosen; radiosurgery to many lesions in selected patients; best supportive care alone in poor-prognosis lung cancer (QUARTZ). (Whole-brain radiotherapy (WBRT), NRG CC001, QUARTZ, IMRT / IGRT (modern external beam))
- Driver-positive lung cancer, asymptomatic metastases: Brain-penetrant targeted therapy first: osimertinib (EGFR), lorlatinib or alectinib (ALK); radiosurgery for progression. (Osimertinib, Lorlatinib, Alectinib, CROWN)
- HER2-positive breast cancer: Tucatinib with trastuzumab and capecitabine (HER2CLIMB) or trastuzumab deruxtecan (DESTINY-Breast12), with local therapy for symptomatic lesions. (Tucatinib, Trastuzumab deruxtecan, HER2CLIMB, DESTINY-Breast12)
- Melanoma: Nivolumab plus ipilimumab for asymptomatic metastases (CheckMate 204); dabrafenib plus trametinib for BRAF V600-mutant disease (COMBI-MB); radiosurgery for symptomatic or progressing lesions. (Nivolumab, Ipilimumab, Dabrafenib + trametinib, Stereotactic radiosurgery (Gamma Knife, CyberKnife, linac SRS))
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
