Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase that has been implicated in the pathogenesis of a variety of neoplasms. As suggested by its name, ALK was first described as part of a translocation product in cases of anaplastic large-cell lymphoma, with other genetic and cytogenetic ALK mutations subsequently coming to attention in the development of many other hematologic and so...

The anaplastic lymphoma kinase (ALK) receptor tyrosine kinase was initially discovered as a component of the fusion protein nucleophosmin (NPM)-ALK in anaplastic large-cell lymphoma (ALCL). Genomic alterations in ALK, including rearrangements, point mutations, and genomic amplification, have now been identified in several malignancies, including lymphoma, non-small cell lung cancer (NSCLC), neu...

Background: Platelet-derived growth factor receptor (PDGFR) is expressed in nucleophosmin–anaplastic lymphoma kinase (NPM-ALK) positive anaplastic large cell lymphomas (ALCL ALK+). Our previous preclinical research suggested that PDGFR blockade by the Abl/c-Kit/PDGFR inhibitor imatinib could be an effective treatment strategy for ALCL ALK+. A young indicator patient whose cells and who failed t...
