NTRK1, NTRK2, and NTRK3 are genes encoding tyrosine kinase receptors and their fusions with other genes are frequent in some rare cancer types (e.g., secretory breast carcinoma), but in NSCLC the prevalence of these alterations is approximately 0.1–1% [61]. Here, NTRK1 is linked to non-small cell lung carcinoma.
