KIF5B/RET fusion gene analysis in a selected series of cytological specimens of EGFR, KRAS and EML4-ALK wild-type adenocarcinomas of the lung

In conclusion, our findings confirm that the performance of cytology-based molecular testing for KIF5B/RET rearrangements is at least as effective as histology-based analysis, both with regard to the success rate for nucleic acid isolation and the ability to detect gene alterations.
