The median tumor mutation burden TMB of these samples is 2. We further elaborately portrayed the TP53 mutation sites on the peptide sequence of the encoded protein by lollipop. The mutational signature and copy number alterations CNAs of the samples were also analyzed. Together, these results may guide personalized clinical management of patients with ALK fusion in the era of precision medicine. These oncogenic mutations could lead to the constitutive activation of the ALK tyrosine kinase domain, and further cause tumorigenesis 3.

Merrida A. Childress , Stephen M. Davies , Christine M. Mol Cancer Res 1 November ; 16 11 : — Oncogenic tyrosine kinase fusions involving the anaplastic lymphoma kinase ALK are detected in numerous tumor types. 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 5—10 fold in drug sensitivity were noted across the seven ALK fusions tested. Finally, biochemical analyses revealed negative correlations between kinase activity and protein stability. As many other kinase fusions are found in numerous cancers, often with overlapping fusion partners, these studies have ramifications for other kinase-driven malignancies. Mol Cancer Res; 16 11 ; — Genomic rearrangements involving the gene which encodes anaplastic lymphoma kinase ALK have been described in a broad spectrum of malignancies including anaplastic large-cell lymphoma ALCL , diffuse large B-cell lymphoma, inflammatory myofibroblastic tumor IMT , glioma, non—small cell lung cancer NSCLC , colorectal, breast, ovarian, and esophageal cancer 1. The resulting ALK fusion proteins all retain the entire kinase domain of ALK at the C-terminus, and the N-terminus consists of an entirely different protein.

Elucidation of on-target resistance mechanisms has facilitated the development of next-generation ALK inhibitors, but overcoming ALK-independent resistance mechanisms remains a challenge.

Yin, The cost-effectiveness and rapid turnaround time of IHC have made it an attractive choice for clinicians and pathologists. Science , — Cancer Discov. Anaplastic lymphoma kinase expression and gene alterations in glioblastoma: correlations with clinical outcome. Am J Surg Pathol ; 40 — Oncotarget 9 , — Conclusions 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. These fusion proteins are validated therapeutic targets. Recurrent inactivating mutations of ARID2 in non-small cell lung carcinoma. Ou, K.

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.

Good clinical response to alectinib, a second generation ALK inhibitor, in refractory neuroblastoma. Published online Feb Although novel ALK fusion variants have been occasionally reported in NSCLC, to our knowledge, the concomitance of double ALK fusion variants in the same lung adenocarcinoma LUAD patient was rare, by far, only 6 cases were reported, median age was 44 range, 29—64 years. Blood Cancer J ; 4 :e These amplifications often result in ligand-dependent activation of downstream ALK signaling pathway.
