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 Oestrogen and progesterone receptor percentage, HER2-negative status, Tumour grade and Ki-67, Nodal stage and tumour size, Oncotype DX recurrence score), 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 (deciding on chemotherapy), which of the standard options do you recommend and why?
- 6.Am I a candidate for Oncotype DX, MammaPrint (70-gene signature), and what side effects should I expect?
- 7.How do the results of TAILORx and RxPONDER (SWOG S1007) apply to someone like me?
- 8.For my situation (endocrine therapy), which of the standard options do you recommend and why?
- 9.Am I a candidate for Letrozole (and other aromatase inhibitors), Exemestane, Tamoxifen or related drugs, and what side effects should I expect?
- 10.How do the results of SOFT & TEXT apply to someone like me?
- 11.For my situation (adjuvant cdk4/6 inhibitor), which of the standard options do you recommend and why?
- 12.Am I a candidate for Abemaciclib, Ribociclib, and what side effects should I expect?
- 13.How do the results of monarchE and NATALEE apply to someone like me?
- 14.For my situation (germline brca carriers), which of the standard options do you recommend and why?
- 15.Am I a candidate for Olaparib, and what side effects should I expect?
- 16.How do the results of OlympiA apply to someone like me?
- 17.For my situation (local therapy), which of the standard options do you recommend and why?
- 18.For my situation (bone protection), which of the standard options do you recommend and why?
- 19.Am I a candidate for Zoledronic acid, Denosumab, and what side effects should I expect?
- 20.Are there clinical trials I could join, for example of lidERA, CAMBRIA-1 & CAMBRIA-2, Study of Pembrolizumab (MK-3475) Versus Placebo in Combination With Neoadjuvant Chemotherapy & Adjuvant Endocrine Therapy in the Treatment of Early-Stage Estrogen Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative (ER+/HER2-) Breast Cancer (MK-3475-756/KEYNOTE-756), Giredestrant?
- 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 “No test yet identifies the women whose relapse will come after ten years, when endocrine therapy has stopped”. How does that affect my plan?
- 24.I read that “Two to three years of a CDK4/6 inhibitor is costly and its overall survival benefit is not yet proven”. How does that affect my plan?
The words I may hear
- Lumpectomy (breast-conserving surgery): Removing only the tumour with a rim of normal breast, keeping the breast; almost always followed by radiotherapy.
- Mastectomy: Removing the whole breast, either for cancer or preventively in BRCA1/2 carriers, where bilateral risk-reducing mastectomy cuts breast cancer risk by 90% or more.
Tests and results to bring
Biomarker results to ask for: Oestrogen and progesterone receptor percentage, HER2-negative status (HER2-low noted for later lines), Tumour grade and Ki-67, Nodal stage and tumour size (monarchE and NATALEE eligibility), Oncotype DX recurrence score (TAILORx, RxPONDER), MammaPrint 70-gene risk (MINDACT), Menopausal status and oestradiol during ovarian suppression, Germline BRCA1 and BRCA2 (OlympiA eligibility).
Scans and tests linked to this cancer: Companion diagnostics, Germline (hereditary) testing, Liquid biopsy (ctDNA), Digital pathology & AI, MRD / molecular residual disease testing, RNA sequencing & expression profiling.
Bring copies of scan reports, pathology and blood results, and a list of every medicine and supplement.
The treatments I may be offered
- Adjuvant CDK4/6 inhibitor: Abemaciclib for two years (monarchE, node-positive high-risk disease) or ribociclib for three years (NATALEE, stage II to III) alongside the aromatase inhibitor. (Abemaciclib, Ribociclib, monarchE, NATALEE, CDK4/6 inhibitors)
- Deciding on chemotherapy: Genomic assay on node-negative and one to three node-positive tumours; chemotherapy for a high recurrence score, for premenopausal women with node-positive disease and a score up to 25, and for clinically high-risk tumours without a low genomic score. (Oncotype DX, MammaPrint (70-gene signature), TAILORx, RxPONDER (SWOG S1007), MINDACT)
- Endocrine therapy: Aromatase inhibitor for postmenopausal women; tamoxifen, or ovarian function suppression with an aromatase inhibitor for premenopausal women at higher risk (SOFT and TEXT); five years, extended to seven to ten in node-positive disease. (Letrozole (and other aromatase inhibitors), Exemestane, Tamoxifen, Goserelin / leuprolide (ovarian function suppression), SOFT & TEXT, Endocrine therapy (SERMs, AIs, SERDs))
- Germline BRCA carriers: One year of adjuvant olaparib after chemotherapy for high-risk disease (OlympiA). (Olaparib, OlympiA, Germline (hereditary) testing)
- Local therapy: Breast-conserving surgery with hypofractionated whole-breast radiotherapy or mastectomy, sentinel node biopsy, and regional nodal irradiation when nodes are involved. (Lumpectomy (breast-conserving surgery), Mastectomy, Sentinel lymph node biopsy, Hypofractionated radiotherapy)
- Bone protection: Zoledronic acid or denosumab during aromatase inhibitor therapy in postmenopausal women reduces fractures, and bisphosphonates also reduce bone recurrence. (Zoledronic acid, Denosumab)
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
