Advanced or recurrent endometrial cancer has spread beyond the uterus or come back after treatment. Chemotherapy plus an immune checkpoint antibody is now the first treatment for everyone, with the biggest gains in mismatch-repair-deficient tumours, and lenvatinib with pembrolizumab is the standard when platinum chemotherapy stops working.
Advanced disease means stage III with nodal or adnexal spread or stage IV with bladder, bowel or distant metastasis, and recurrence after primary treatment behaves in the same way. Treatment begins with surgery where debulking is feasible, then systemic therapy chosen by mismatch-repair status and, increasingly, HER2 and hormone receptor status. Carboplatin-paclitaxel had been the first-line standard since GOG-0209 showed it as effective as and less toxic than the older three-drug regimen, and for pelvic-confined recurrence radiotherapy or exenteration can still be curative.
Three phase 3 trials reported in 2023 changed first-line care. RUBY added dostarlimab to carboplatin-paclitaxel and extended median overall survival in the whole population from 28.2 to 44.6 months, with a hazard ratio of 0.69 and a progression-free survival hazard ratio of 0.28 in mismatch-repair-deficient tumours. NRG-GY018 added pembrolizumab and cut the hazard of progression to 0.30 in deficient and 0.54 in proficient tumours. DUO-E added durvalumab, with a hazard ratio of 0.42 in deficient tumours, and durvalumab plus olaparib maintenance gave 0.57 in proficient tumours. Regulators approved pembrolizumab and dostarlimab with chemotherapy for all comers in 2024, and the gain in proficient disease, though real, is smaller and the subject of debate about cost and toxicity.
| Setting | Approach | Guideline |
|---|---|---|
| First line, dMMR | Carboplatin-paclitaxel with dostarlimab (RUBY) or pembrolizumab (NRG-GY018), then maintenance immunotherapy for up to three years or two years respectively. | not mapped |
| First line, pMMR | Carboplatin-paclitaxel with pembrolizumab or dostarlimab, or durvalumab followed by durvalumab-olaparib maintenance (DUO-E); trastuzumab added for HER2-positive serous carcinoma. | not mapped |
| After platinum, pMMR | Lenvatinib with pembrolizumab (KEYNOTE-775); trastuzumab deruxtecan for HER2-expressing tumours; aromatase inhibitors or progestins for low-grade receptor-positive disease. | not mapped |
| After platinum, dMMR without prior immunotherapy | Single-agent dostarlimab or pembrolizumab. | not mapped |
| Isolated pelvic recurrence | Radiotherapy with brachytherapy for vaginal recurrence after surgery alone; exenteration in selected central recurrences after radiotherapy. | not mapped |
