PD‐L1 expression in <i>ROS1</i>‐rearranged non‐small cell lung cancer: A study using simultaneous genotypic screening of <i>EGFR</i>, <i>ALK</i>, and <i>ROS1</i>

Abstract

In the largest consecutive routine Asian NSCLC cohort analyzed to date, we found that high PD-L1 expression frequently overlapped with ROS1 rearrangement, while it negatively correlated with EGFR mutations.
