Targeted RNA‐sequencing assays: a step forward compared to FISH and IHC techniques?

Abstract

Our findings assessed the implementation of RNA-sequencing approaches to explore ALK and ROS1 rearrangements from formalin-fixed paraffin-embedded samples. We highlighted the similarities between Qiagen^® and Archer^® kits in terms of handling time, cost, and outcomes. We confirmed the feasibility of molecular testing in routine organization and its possible use not only as an alternative for standard IHC and FISH techniques, but as a supplementary technique helping to classify discrepant cases.
