 EML4-ALK is a lung cancer oncogene, and ALK inhibitors show marked therapeutic efficacy for tumors harboring this fusion gene.     ///    Screening for EML4-ALK and KIF5B-ALK with our RT-PCR system identified EML4-ALK transcripts in 36 samples (4.46%) from 32 individuals (4.24%).    ///    We here tested whether reverse transcription PCR (RT-PCR)-based detection of EML4-ALK is a sensitive and reliable approach.     ///    We propose that diagnostic tools for EML4-ALK should be selected in a manner dependent on the available specimen types.     ///    A prospective PCR-based screening for the EML4-ALK oncogene in non-small cell lung cancer..
