... IHC testing revealed positive PD-L1 expression in 33.66% (34/101) cases; of these, majority (67.65%, 23/34) of the patients had PD-L1 TPS of <50% and 32.35% (11/34) patients had TPS of ≥50% [ Figure 1]; none of the patients showed <1% TPS. PD-L1 expression was present in 18.1% (2/11) patients with EGFR mutation (TPS: <50% in both patients), 50% (4/8) ALK-IHC positive cases (TPS <50%: 2, TPS ≥50%: 2), and 33.3% (3/10) ALK-FISH positive cases (TPS <50%: 2, TPS ≥50%: 1) [ Figure 1]. ...

In patients with PD-L1 expression, EGFR mutation was present in 5.9% (2/34) patients, ALK-IHC rearrangement in 11.8% (4/34), and ALK-FISH rearrangement in 8.8% (3/34) patients. ...
