Predictive biomarkers in the setting of non–small cell lung cancer (NSCLC) include gene fusions in tumors that have rearranged during transfection (RET). In NSCLC, chromosomal rearrangements between the RET gene and another domain lead to overexpression of the RET protein. These gene fusions have been identified as oncogenic drivers in multiple tumor types. They have the potential to cause chimeric, cytosolic proteins with constitutively active RET kinase domain, leading to increased cell proliferation, migration, and survival.
