TLDR
The clinical outcomes with targeted therapies, aetiologic, pathogenic and clinical features that are associated with cancers harbouring oncogenic fusion kinases, including anaplastic lymphoma kinase (ALK), ROS1 and RET are examined.
Abstract
In this Review, the authors examine the aetiological, pathogenic and clinical features that are associated with cancers harbouring oncogenic fusion kinases, the clinical outcomes with targeted therapies, and strategies to discover additional kinases that are activated by chromosomal rearrangements in solid tumours. Chromosomal rearrangements that lead to oncogenic kinase activation are observed in many epithelial cancers. These cancers express activated fusion kinases that drive the initiation and progression of malignancy, and often have a considerable response to small-molecule kinase inhibitors, which validates these fusion kinases as 'druggable' targets. In this Review, we examine the aetiologic, pathogenic and clinical features that are associated with cancers harbouring oncogenic fusion kinases, including anaplastic lymphoma kinase (ALK), ROS1 and RET. We discuss the clinical outcomes with targeted therapies and explore strategies to discover additional kinases that are activated by chromosomal rearrangements in solid tumours.

Erratum: Non-small-cell lung cancers: a heterogeneous set of diseases

TL;DR: ADCs can be modelled by KrasG12D expression (long latency), KrasD expression and Trp53-null, and epidermal growth factor receptor (EGFR)T790M/L858R, among other genetic models, and they are thought to arise from more distal airway cells.

The landscape and therapeutic relevance of cancer-associated transcript fusions.

TL;DR: The landscape of transcript fusions detected across a large number of tumor samples was described and revealed fusion events with clinical relevance that have not been previously recognized, support the concept of basket clinical trials and reveal an important role for tumorigenesis.

BIM Mediates EGFR Tyrosine Kinase Inhibitor-Induced Apoptosis in Lung Cancers with Oncogenic EGFR Mutations

TL;DR: Evidence is provided that BIM is involved in TKI- induced apoptosis in sensitive EGFR-mutant cells and that both attenuation of the up-regulation of BIM and resistance to gefitinib-induced apoptosis are seen in models that contain the common EGFR T790M and the novel L747S secondary resistance mutations.

A transforming KIF5B and RET gene fusion in lung adenocarcinoma revealed from whole-genome and transcriptome sequencing

TL;DR: It is demonstrated that a subset of NSCLCs could be caused by a fusion of KIF5B and RET, and suggested the chimeric oncogene as a promising molecular target for the personalized diagnosis and treatment of lung cancer.

RET Fusions Define a Unique Molecular and Clinicopathologic Subtype of Non–Small-Cell Lung Cancer

TL;DR: The RET fusion gene occurs in 1.4% of NSCLCs and 1.7% of lung adenocarcinomas and has identifiable clinicopathologic characteristics, warranting further clinical consideration and targeted therapy investigation.
