Stage Stage IIB
Tumor with ipsilateral hilar/peribronchial nodal involvement, or tumor >5–7 cm (T1-2/N1 or T3/N0, M0). Potentially resectable.
2 test recommendations across 1 clinical indication
Stage IIB squamous NSCLC. Comprehensive molecular profiling now recommended by NCCN for squamous NSCLC regardless of stage, as targeted therapy options expand.
Required — 2 tests
Comprehensive Solid Tumor NGS Panel
Comprehensive NGS
Next-generation sequencing panel covering ≥300 cancer-relevant genes, including all major NSCLC drivers (EGFR, ALK, ROS1, BRAF, KRAS, MET, RET, NTRK, HER2, FGFR), plus tumor mutational burden (TMB) and microsatellite instability (MSI). Examples include FoundationOne CDx, Tempus xT, Caris MI Transcriptome, and equivalent institutional panels. Preferred over single-gene sequential testing for efficiency and cost-effectiveness.
Ordering Note
NCCN recommends broad molecular profiling for squamous NSCLC. Targetable alterations present in ~15–20% including KRAS G12C, BRAF V600E, FGFR1 amplification, MET alterations, NTRK fusions.
Specimen
PD-L1 Expression by Immunohistochemistry (IHC)
PD-L1 IHC
Measurement of PD-L1 (programmed death-ligand 1; CD274) protein expression on tumor cells by IHC. Reported as Tumor Proportion Score (TPS) for NSCLC. Key thresholds: TPS <1% (PD-L1 negative), TPS 1–49% (low expression), TPS ≥50% (high expression). FDA-approved companion diagnostics: 22C3 pharmDx (pembrolizumab), 28-8 pharmDx (nivolumab), SP142 (atezolizumab), SP263 (durvalumab). PD-L1 ≥50% qualifies for pembrolizumab monotherapy first-line; all TPS levels are relevant for combination chemo-immunotherapy selection.
