ReviewTargeted therapies in non-small cell lung cancer: emerging oncogene targets following the success of epidermal growth factor receptor.
The diagnostic testing, treatment and prognosis of non-small cell lung cancer (NSCLC) has undergone a paradigm shift since the discovery of sensitizing mutations in the epidermal growth factor receptor (EGFR) gene in a subset of NSCLC patients. Several additional oncogenic mutations, including gene fusions and amplifications, have since been discovered, with a number of drugs that target each specific oncogene. This review focuses on oncogenes in NSCLC other than EGFR and their companion "targeted therapies." Particular emphasis is placed on the role of ALK, ROS1, RET, MET, BRAF, and HER2 in NSCLC.

Biologics are important treatments for a number of cancers. Patents for several biologics will expire over the next decade, removing a barrier to the development and commercialization of biosimilars. As biologics differ from small-molecule drugs due to their size and complexity, multifaceted manufacturing process, and their potential for immunogenicity, biosimilars cannot be considered "generic versions" of currently approved biologics. ⋯ The European Medicines Agency has approved a number of biosimilars and the recent approval of the biosimilar infliximab monoclonal antibody is another regulatory milestone. This article will provide context regarding key safety issues addressed in biosimilar development, approval, and delivery, as well as inform oncologists on matters of safety to consider when prescribing biosimilars. Pertinent issues about safety from countries or regions where biosimilars are currently in use also will be reviewed.
