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.

A common BIM deletion polymorphism mediates intrinsic resistance and inferior responses to tyrosine kinase inhibitors in cancer.

TL;DR: The results offer an explanation for the heterogeneity of TKI responses across individuals and suggest the possibility of personalizing therapy with BH3 mimetics to overcome BIM-polymorphism–associated TKI resistance.

Spatial Organization of the Mouse Genome and Its Role in Recurrent Chromosomal Translocations

TL;DR: A high-resolution Hi-C spatial organization map of the G1-arrested mouse pro-B cell genome is generated and high-throughput genome-wide translocation sequencing is used to map translocations from target DNA double-strand breaks (DSBs) within it.

Phase II Trial of Sorafenib in Metastatic Thyroid Cancer

TL;DR: Sorafenib is reasonably well-tolerated therapy with clinical and biologic antitumor activity in metastatic PTC and four of 10 paired tumor biopsies from PTC patients showed a reduction in levels of vascular endothelial growth factor receptor phosphorylated, ERK phosphorylation, and in VEGF expression during sorafenIB therapy.
