الوصف: ALK , ROS1 , and RET fusions and MET ∆ex14 variant associate with response to targeted therapies in non‐small‐cell lung cancer (NSCLC). Technologies for fusion testing in tissue must be adapted to liquid biopsies, which are often the only material available. In this study, circulating‐free RNA (cfRNA) and extracellular vesicle RNA (EV‐RNA) were purified from liquid biopsies. Fusion and MET ∆ex14 transcripts were analyzed by nCounter (Nanostring) and digital PCR (dPCR) using the QuantStudio ® System (Applied Biosystems). We found that nCounter detected ALK , ROS1 , RET , or MET ∆ex14 aberrant transcripts in 28/40 cfRNA samples from positive patients and 0/16 of control individuals (70% sensitivity). Regarding dPCR, aberrant transcripts were detected in the cfRNA of 25/40 positive patients. Concordance between the two techniques was 58%. Inferior results were obtained when analyzing EV‐RNA, where nCounter often failed due to a low amount of input RNA. Finally, results of dPCR testing in serial liquid biopsies of five patients correlated with response to targeted therapy. We conclude that nCounter can be used for multiplex detection of fusion and MET ∆ex14 transcripts in liquid biopsies, showing a performance comparable with next‐generation sequencing platforms. dPCR could be employed for disease follow‐up in patients with a known alteration. cfRNA should be preferred over EV‐RNA for these analyses.
