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.

TRKB tyrosine kinase receptor is a potential therapeutic target for poorly differentiated oral squamous cell carcinoma.

TL;DR: The results obtained through immunohistochemical analysis of human OSCC tumor specimens showed that the expression levels of TRKB and/or BDNF, were significantly higher in moderately and poorly differentiated OSCC (MD/PD- OSCC) tumor cells than in well differentiated cells (WD-OSCC).

A novel fusion of HNRNPA1–ALK in inflammatory myofibroblastic tumor of urinary bladder

TL;DR: A 42-year-old Japanese man underwent total cystectomy because of an invasive urinary bladder tumor, which comprised spindle neoplastic cells with intermingled inflammatory cells and a novel transcript fusion of exon 2 of HNRNPA1 and exon 18 of ALK, resulting in ALK protein overexpression.

Oncogenic Function of a KIF5B-MET Fusion Variant in Non-Small Cell Lung Cancer

TL;DR: The KIF5B-MET variant was demonstrated to have an oncogenic function in cancer cells and have immediate clinical implications for the targeted therapy of subgroups of non-small cell lung cancer patients.

Estimates of worldwide burden of cancer in 2008: GLOBOCAN 2008.

TL;DR: The results for 20 world regions are presented, summarizing the global patterns for the eight most common cancers, and striking differences in the patterns of cancer from region to region are observed.

Identification of the transforming EML4–ALK fusion gene in non-small-cell lung cancer

TL;DR: It is shown that a small inversion within chromosome 2p results in the formation of a fusion gene comprising portions of the echinoderm microtubule-associated protein-like 4 (EML4) gene and the anaplastic lymphoma kinase (ALK) gene in non-small-cell lung cancer (NSCLC) cells.
