| Evidence summary | MSI-H/dMMR endometrial cancer (~25-30% of advanced cases) qualifies for ICI-based regimens. Dostarlimab + carboplatin + paclitaxel 1L (RUBY trial; mOS NR vs 36.7 mo, HR 0.64 in dMMR/MSI-H subgroup; FDA-approved 2023). Pembrolizumab + carboplatin + paclitaxel 1L (KEYNOTE-868/NRG-GY018; FDA-approved 2023 for dMMR/MSI-H). Also pembrolizumab monotherapy 2L+ for MSI-H/dMMR endometrial (KEYNOTE-158; FDA-approved 2017 tumor-agnostically). MSI/MMR testing mandatory at diagnosis of advanced/recurrent endometrial cancer per NCCN/ESMO. Indication selection enforced by algorithm layer (IND-ENDOMETRIAL-DMMR); this BMA surfaces ESCAT context only. |
Notes
Variant_qualifier "MSI-H" matches positive MSI-H patient values. RUBY (SRC-RUBY) and KEYNOTE-868 source stubs not yet ingested — citing NCCN/ESMO as proxies. BIO-DMMR-IHC BMAs cover the IHC-based pathway; this entry covers the PCR/NGS-based MSI result as an equivalent eligibility input.
