Red flags — PRO / CONTRA aggressive

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).
