According to statistics, co‐mutations in FGF/FGFR and NOTCH1 (3.81%, 14/367, 8 PV and 6 VUS) are associated with significantly higher PD‐L1 expression ratio compared to cases without NOTCH1 co‐mutations (with NOTCH1 co‐mutations: Tumor proportion score (TPS) ≥ 50% 28.57%, 4/14; others: TPS ≥ 50% 11.61%, 41/353, Figure 5C). Here, NOTCH1 is linked to neoplasm.
