Diagnostic Pathology volume 17 , Article number: 27 Cite this article. Metrics details. However, co-occurrence of double ALK fusions in one patient was rare. In both patients, tumor cells displayed strong expression of ALK protein. Genetic profiling by next generation sequencing showed both patients concurrently harbored two types of ALK rearrangements. Both of these patients responded to ALK inhibitor crizotinib. Our study reported two novel ALK fusion partners never reported, which expands the knowledge of ALK fusion spectrum and provides insight into therapeutic options for patients with double ALK fusions. It create an oncogenic ALK tyrosine kinase, which activates many downstream signaling pathways, leading to increased cell proliferation and survival [ 2 ]. In addition, ALK rearrangement enriched in younger aged adenocarcinoma patients who never smoked or are light smokers. With the popularity of next-generation sequencing NGS technology, more and more rare rearrangement types will be discovered. Application of ALK targeting tyrosine kinase inhibitors such as crizotinib [ 9 ], ceritinib [ 10 ], alectinib [ 11 ], and brigatinib [ 12 ], have largely improved prognosis as well as life quality of ALK fusion-positive NSCLC patients.

Note that blue is representative of increased expression from the meanand red is decreased expression from the mean. Unfortunately, alk fusion partners, this study was terminated early and since enrollment was only based on ALK positive immunohistochemistry, there is no data on types of ALK alterations included in the glioblastoma cohort available in public domain.

Oncogenic tyrosine kinase fusions involving the anaplastic lymphoma kinase ALK are detected in numerous tumor types. Although more than 30 disti nct 5 ' fusion partner genes have been reported, treatment of ALK -rearranged cancers is decided without regard to which 5' partner is present. There is little data addressing how the 5' partner affects the biology of the fusion or responsiveness to ALK tyrosine kinase inhibitors TKI. On the basis of the hypothesis that the 5' partner influences the intrinsic properties of the fusion protein, cellular functions that impact oncogenic potential, and sensitivity to ALK TKIs, clonal 3T3 cell lines stably expressing seven different ALK fusion variants were generated. Biochemical and cellular assays were used to assess the efficacy of various ALK TKIs in clinical use, transformative phenotypes, and biochemical properties of each fusion. All seven ALK fusions induced focus formation and colonies in soft agar, albeit to varying degrees. IC 50 s were calculated for different ALK TKIs crizotinib, ensartinib, alectinib, lorlatinib and consistent differences fold in drug sensitivity were noted across the seven ALK fusions tested. Finally, biochemical analyses revealed negative correlations between kinase activity and protein stability.
