Predictive biomarkers in NSCLC include anaplastic lymphoma kinase (ALK) fusion oncogene, ROS proto-oncogene 1 receptor tyrosine kinase (ROS1) gene fusions, sensitizing endothelial growth factor receptor (EGFR) gene mutations, BRAF V600E point mutations, neurotrophin tyrosine kinase (NTRK) gene fusions, c-mesenchymal-epithelial transition factor (c-MET) exon 14 (METex14) skipping mutations and RET rearrangements [8]. Here, ALK is linked to non-small cell lung carcinoma.
