The words I may hear
- Endometrial cancer molecular classes (POLEmut, MMRd, p53abn, NSMP): Four groups defined by a few tests that predict outcome better than the microscope: POLE-mutated (excellent), mismatch-repair deficient, p53-abnormal (worst), and 'no specific profile'.
- Glycaemic index and glycaemic load: How fast a food raises blood sugar (index) and how much, given the portion (load).
- Microsatellite-stable (MSS) / mismatch-repair proficient (pMMR): The 'normal' result on the mismatch-repair test: the tumour has intact DNA spell-checking and few mutations.
- Lynch syndrome: Lynch syndrome is the most common inherited cancer syndrome: a faulty mismatch-repair gene raises lifetime bowel cancer risk to 40-80% and also endometrial and other cancers.
- Hysterectomy: Removing the uterus (womb), often with the cervix, tubes and ovaries.
- Metabolic syndrome and insulin resistance: Metabolic syndrome is a cluster of central obesity, high blood pressure, high blood sugar and abnormal blood fats.
- TP53-mutated (p53-abnormal): Loss of the p53 'guardian of the genome', the most commonly mutated gene in cancer.
- Microsatellite instability (MSI-H) / mismatch repair deficiency (dMMR): Microsatellite instability is the mark of a broken DNA spell-checker (loss of MLH1, MSH2, MSH6 or PMS2) that leaves thousands of mutations, so the tumour displays abnormal proteins that T cells can recognise.
- Tumour-agnostic (tissue-agnostic) approval: A tumour-agnostic approval lets a drug be used for any cancer carrying a specific molecular feature, regardless of where it started.
- Obesity-related cancers (IARC list of 13): Excess body fat is an established cause of thirteen cancers on the IARC list, including womb, oesophagus, kidney, liver, bowel, pancreas and postmenopausal breast cancer.
Tests and results to bring
Diagnosis and staging: Endometrial biopsy for postmenopausal bleeding; MRI for myometrial and cervical invasion; molecular classification (p53, MMR IHC, POLE sequencing) on the diagnostic specimen.
Biomarker results to ask for: MMR/MSI, POLE, p53, HER2 (serous), ER/PR, TROP2, MMR IHC / MSI (dMMR ~25-30%; Lynch syndrome in ~3% of all cases), POLE exonuclease-domain mutation, p53 IHC, HER2 IHC/ISH (serous, p53abn), L1CAM (NSMP risk), CTNNB1 (NSMP low-grade recurrence risk), PD-L1 (limited utility), FRα and TROP2 (ADC trials), ARID1A, PIK3CA, PTEN (targetable in trials).
Scans and tests linked to this cancer: Companion diagnostics, Germline (hereditary) testing, Histopathology & immunohistochemistry, MRI, MSI and mismatch-repair testing, 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
- Prevention and hereditary risk: Universal MMR testing of tumours to identify Lynch syndrome; risk-reducing hysterectomy and salpingo-oophorectomy for Lynch carriers after childbearing; levonorgestrel IUD and weight management reduce risk; no screening for average-risk women. (Germline (hereditary) testing, Microsatellite instability (MSI-H) / mismatch repair deficiency (dMMR), Progestins (megestrol acetate, medroxyprogesterone, levonorgestrel IUD))
- Early: Hysterectomy; adjuvant therapy by molecular class.
- Early stage surgery: Minimally invasive total hysterectomy and bilateral salpingo-oophorectomy with sentinel lymph node mapping (FIRES, SENTOR); omentectomy for serous histology. (Robotic & minimally invasive surgery, Sentinel lymph node biopsy, FIRES & SENTOR (sentinel node mapping))
- Adjuvant, low and intermediate risk: Observation (low risk, POLEmut) or vaginal brachytherapy (intermediate risk; PORTEC-2); molecular class may de-escalate (PORTEC-4a). (Brachytherapy, Endometrial cancer molecular classes (POLEmut, MMRd, p53abn, NSMP))
- Adjuvant, high risk (stage III, serous, p53abn, deep invasion grade 3): Chemoradiation plus carboplatin-paclitaxel (PORTEC-3) or chemotherapy alone (GOG-258); pembrolizumab or dostarlimab added for stage III-IV per RUBY/GY018 eligibility. (PORTEC-3, Carboplatin, Paclitaxel / nab-paclitaxel, IMRT / IGRT (modern external beam), Pembrolizumab, Dostarlimab)
- Advanced/recurrent: Chemotherapy + dostarlimab or pembrolizumab; lenvatinib-pembrolizumab; T-DXd if HER2+. (Dostarlimab, Pembrolizumab, Trastuzumab deruxtecan)
- Fertility-sparing (grade 1, stage IA, no invasion): Progestin (oral or IUD) with re-biopsy every 3-6 months; hysterectomy after childbearing. (Fertility-sparing hormonal treatment of early endometrial cancer, Progestins (megestrol acetate, medroxyprogesterone, levonorgestrel IUD))
- Advanced or recurrent, first line (any MMR status): Carboplatin-paclitaxel plus dostarlimab (RUBY), pembrolizumab (NRG-GY018/KEYNOTE-868), or durvalumab (DUO-E; dMMR in the US), continued as maintenance up to 2-3 years. (RUBY / ENGOT-EN6 / GOG-3031, NRG-GY018 / KEYNOTE-868, DUO-E / GOG-3041 / ENGOT-EN10, Dostarlimab, Pembrolizumab, Durvalumab, Chemotherapy + PD-1/PD-L1 blockade, first-line advanced endometrial cancer)
- Recurrent, dMMR, after chemotherapy: Single-agent PD-1 blockade (dostarlimab GARNET, pembrolizumab) if immunotherapy-naive; otherwise chemotherapy or trials. (Dostarlimab, Pembrolizumab, Microsatellite instability (MSI-H) / mismatch repair deficiency (dMMR))
- HER2-positive serous: Trastuzumab with carboplatin-paclitaxel (randomised phase 2) or T-DXd for IHC 3+ after prior therapy. (Trastuzumab, Trastuzumab deruxtecan, HER2, DESTINY-PanTumor02)
- Recurrent, pMMR, after platinum: Lenvatinib + pembrolizumab (KEYNOTE-775) if not previously given immunotherapy; T-DXd if HER2 IHC 3+; chemotherapy (doxorubicin, weekly paclitaxel); hormonal therapy for low-grade ER-positive disease. (Lenvatinib, Pembrolizumab, KEYNOTE-775 / Study 309, Trastuzumab deruxtecan, DESTINY-PanTumor02, Letrozole (and other aromatase inhibitors), Progestins (megestrol acetate, medroxyprogesterone, levonorgestrel IUD))
From the standard of care recorded for this cancer; which apply depends on your stage and biomarkers. Ask which the team recommends and why.
