In             this study, we have independently investigated the KIF5B/RET fusion gene status             in 371?surgically-treated NSCLCs (270 were adenocarcinomas and 101 were squamous             cell carcinomas), 60 breast cancers, 11?metastatic lung cancers from colon cancers             and thyroid papillary adenocarcinoma cases at the Nagoya City University Hospital.     ///    We detected 3 of 270 cases of KIF5B/RET fusion genes in adenocarcinomas             (1.1%) consisting of female and never smokers with mixed subtype adenocarcinomas.     ///    "However,             the correlation between the KIF5B/RET fusion gene status and the clinicopathological             features of surgically-treated lung cancer has not been well characterized.
