The detection of NTRK gene fusion is recommended by the National Comprehensive Cancer Network (NCCN) clinical practice guidelines, and the TRK inhibitors (larotrectinib and entrectinib) are preferred as the first-line treatment for locally advanced or metastatic patients with NTRK-fusion-positive NSCLC (8). Here, NTRK1 is linked to non-small cell lung carcinoma.
