The 20-gene ICR signature was independently associated with benefit from anti-PD1/PDL1 ICI in patients with advanced NSCLC. Validation in larger retrospective and prospective series is warranted.
We identified a feasible transcriptomic signature with a promising signal of ICI efficacy prediction in the so far disappointing immune biomarkers field. In a near future, predict ICI efficacy will be a major challenge with three pivotal questions. When, balanced with the new data on ICI use in early-stage lung cancer or widely pretreated patients.
