Medición
MétodoIHC with VENTANA PD-L1 (SP142) Assay on BenchMark ULTRA / XT. Scoring is IMMUNE-CELL-WEIGHTED (distinct from 22C3 / SP263): - TNBC: IC score = % tumor area occupied by PD-L1+ immune cells of any intensity; positive cut-off IC ≥1%. - Urothelial (historical): IC ≥5%. - NSCLC (atezolizumab IMpower150 era): TC ≥50% OR IC ≥10% ("TC3 or IC3").

Notas

Companion-diagnostic clone-specific entity for atezolizumab. Important for engine: a TNBC patient with a 22C3 CPS result CANNOT be routed through an SP142-IC-based atezo regimen and vice versa — clones are not interchangeable. Render layer should surface assay-mismatch warnings. TRIAL ANCHOR: IMpassion130 (Schmid et al, NEJM 2018) — primary validating trial; full Source stub TBD (flag for source-ingest follow-up). Currently citing NCCN guidelines that summarize the evidence and SP142-specific cut-points.
