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. The first approved is Crizotinib which is the first generation TKI.

Thirty-four of the distinct fusion partners are located on the short arm of chromosome 2; 28 of these 34 fusion partners are located on 2p, in which ALK is located on 2p In addition, at least 28 intergenic ALK rearrangements have also been reported, with three of them reported as responding to crizotinib. We aim to update and improve the list going forward. In this article, we have compiled a list of the ALK fusion partners including intergenic rearrangements identified in the literature for easy reference. Overall, a total of 90 distinct ALK fusion partners including noncoding RNAs have been identified in the literature by the end of January Table 1. Twenty-five intergenic rearrangements to exon 20 of ALK have also been identified and listed separately in Table 2. Three of these intergenic ALK rearrangements have been shown to respond to crizotinib, but the significance of these intergenic rearrangements remains to be determined, including whether functional fusion RNAs are translated from these intergenic rearrangements. The column entry is for the later discovery of ALK fusion partners.

Moreover, there are numerous reports of ALK inhibitor activity in multiple solid and hematologic tumors e. Many reports used crizotinib or alectinib, but each of the approved ALK inhibitors have shown activity.

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.

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