Other Idylla cartridges that might be useful in NSCLC exist (i.e., the KRAS and BRAF tests) [126], and another interesting cartridge is in development (currently for research use only), targeting ALK, ROS1, RET, and NTRK1/2/3 rearrangements as well as MET exon 14 skipping. The gene discussed is RET; the disease is non-small cell lung carcinoma.
