Pan-tumor MSI-H ICI eligibility (pembrolizumab per KEYNOTE-158, dostarlimab per GARNET) supersedes tumor-specific lines via tissue-agnostic FDA approval. Advanced/recurrent dMMR endometrial: dostarlimab + carbo/paclitaxel 1L (RUBY) and pembrolizumab + carbo/paclitaxel (NRG-GY018) doubled PFS. Dostarlimab/pembrolizumab monotherapy in 2L+.

Also pembrolizumab monotherapy 2L+ for MSI-H/dMMR endometrial (KEYNOTE-158; FDA-approved 2017 tumor-agnostically).

PRO-AGGRESSIVE

Triggers that push toward the aggressive track

Patient with active or incompletely controlled pre-existing autoimmune or inflammatory disease (sarcoidosis, rheumatoid arthritis, IBD, SLE, autoimmune hepatitis, inflammatory myopathy, myasthenia gravis, or similar) is considered for immune checkpoint inhibitor (ICI) therapy — elevated risk of immune-related adverse events (irAE) flare or de-novo grade 3-4 irAE. Requires specialist (rheumatology / pulmonology / gastroenterology) pre-treatment review; prefer lower-irAE-burden backbone when options exist (pembrolizumab mono > ipilimumab+nivolumab).
Pre-existing autoimmune disease is present in ~10-15% of patients eligible for ICI therapy; historically excluded from pivotal trials. Real-world data (Abdel-Wahab 2018, 3557 pts) shows 55% experienced irAE flare and ~29% required…
