Abstract

Through an integrated molecular- and histopathology-based screening system, we performed a screening for fusions of anaplastic lymphoma kinase (ALK) and c-ros oncogene 1, receptor tyrosine kinase (ROS1) in 1,529 lung cancers and identified 44 ALK-fusion-positive and 13 ROS1-fusion-positive adenocarcinomas, including for unidentified fusion partners for ROS1. In addition, we discovered previously unidentified kinase fusions that may be promising for molecular-targeted therapy, Kinesin family member 5B (KIF5B)-ret proto-oncogene (RET) and coiled-coil domain containing 6 (CCDC6)-RET, in 14 adenocarcinomas. A multivariate analysis of 1,116 adenocarcinomas containing these 71 kinase-fusion-positive adenocarcinomas identified four independent factors that are Indicators of poor prognosis: age ≥ 50 years, male sex, high pathological stage and negative kinase-fusion status.
