To date, limited genetic analyses confirmed KIT mutations as a recurrent genetic event similar to other mucosal melanomas, occurring in up to 30% of anorectal melanomas. Importantly, a subset of tumors harboring activating KIT mutations have been found to respond to c-Kit inhibitor-based therapy, with improved patient survival at advanced tumor stages. We performed comprehensive targeted exon sequencing analysis of 467 cancer-related genes in a larger series of 15 anorectal melanomas, focusing on potentially actionable variants based on gain- and loss-of-function mutations. We report the identification of oncogenic driver events in the majority (93%) of anorectal melanomas. These included variants in canonical MAPK pathway effectors rarely observed in cutaneous melanomas (including an HRAS mutation, as well as a BRAF mutation resulting in duplication of threonine 599), and recurrent mutations in the tumor suppressor NF1 in 20% of cases, which represented the second-most frequently mutated gene after KIT in our series. -

Targeted Therapies in Advanced Cholangiocarcinoma: a Focus on FGFR Inhibitors
medicina Review Targeted Therapies in Advanced Cholangiocarcinoma: A Focus on FGFR Inhibitors Alessandro Rizzo Department of Experimental, Diagnostic and Specialty Medicine, S. Orsola-Malpighi University Hospital, 40138 Bologna, Italy; [email protected] Abstract: Despite advanced diseases continuing to be associated with grim prognoses, the past decade has witnessed the advent of several novel treatment options for cholangiocarcinoma (CCA) patients. In fact, CCA has emerged as a heterogeneous group of malignancies harboring potentially druggable mutations in approximately 50% of cases, and thus, molecularly targeted therapies have been actively explored in this setting. Among these, fibroblast growth factor receptor (FGFR) inhibitors have reported important results, as witnessed by the FDA approval of pemigatinib in previously treated metastatic CCA patients harboring FGFR2 fusion or other rearrangements. Herein, we provide an overview of available evidence on FGFR inhibitors in CCA, especially focusing on the development, pitfalls and challenges of emerging treatments in this setting.

MET Or NRAS Amplification Is an Acquired Resistance Mechanism to the Third-Generation EGFR Inhibitor Naquotinib
www.nature.com/scientificreports OPEN MET or NRAS amplifcation is an acquired resistance mechanism to the third-generation EGFR inhibitor Received: 5 October 2017 Accepted: 16 January 2018 naquotinib Published: xx xx xxxx Kiichiro Ninomiya1, Kadoaki Ohashi1,2, Go Makimoto1, Shuta Tomida3, Hisao Higo1, Hiroe Kayatani1, Takashi Ninomiya1, Toshio Kubo4, Eiki Ichihara2, Katsuyuki Hotta5, Masahiro Tabata4, Yoshinobu Maeda1 & Katsuyuki Kiura2 As a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), osimeritnib is the standard treatment for patients with non-small cell lung cancer harboring the EGFR T790M mutation; however, acquired resistance inevitably develops. Therefore, a next-generation treatment strategy is warranted in the osimertinib era. We investigated the mechanism of resistance to a novel EGFR-TKI, naquotinib, with the goal of developing a novel treatment strategy. We established multiple naquotinib-resistant cell lines or osimertinib-resistant cells, two of which were derived from EGFR-TKI-naïve cells; the others were derived from geftinib- or afatinib-resistant cells harboring EGFR T790M. We comprehensively analyzed the RNA kinome sequence, but no universal gene alterations were detected in naquotinib-resistant cells. Neuroblastoma RAS viral oncogene homolog (NRAS) amplifcation was detected in naquotinib-resistant cells derived from geftinib-resistant cells. The combination therapy of MEK inhibitors and naquotinib exhibited a highly benefcial efect in resistant cells with NRAS amplifcation, but the combination of MEK inhibitors and osimertinib had limited efects on naquotinib-resistant cells. Moreover, the combination of MEK inhibitors and naquotinib inhibited the growth of osimertinib-resistant cells, while the combination of MEK inhibitors and osimertinib had little efect on osimertinib-resistant cells. -

ORCID: 0000-0001-9087-1616 6 ORCID: 0000-0001-8509-1500 * Corresponding author: [email protected] Abstract Mutations and gene amplifications that confer drug resistance emerge frequently during chemotherapy, but their mechanism and timing is poorly understood. Here, we investigate BRAFV600E amplification events that underlie resistance to the MEK inhibitor selumetinib (AZD6244/ARRY-142886) in COLO205 cells. We find that de novo focal BRAF amplification is the primary path to resistance irrespective of pre-existing amplifications. Although selumetinib causes long-term G1 arrest, we observe that cells stochastically re-enter the cell cycle during treatment without reactivation of ERK1/2 or induction of a normal proliferative gene expression programme. Genes encoding DNA replication and repair factors are downregulated during G1 arrest, but many are transiently induced when cells escape arrest and enter S and G2. -
New Horizons for Precision Medicine in Biliary Tract Cancers
Published OnlineFirst August 17, 2017; DOI: 10.1158/2159-8290.CD-17-0245 REVIEW New Horizons for Precision Medicine in Biliary Tract Cancers Juan W. Valle1,2, Angela Lamarca1, Lipika Goyal3, Jorge Barriuso1,4, and Andrew X. Zhu3 ABSTRACT Biliary tract cancers (BTC), including cholangiocarcinoma and gallbladder cancer, are poor-prognosis and low-incidence cancers, although the incidence of intrahe- patic cholangiocarcinoma is rising. A minority of patients present with resectable disease but relapse rates are high; benefit from adjuvant capecitabine chemotherapy has been demonstrated.Cisplatin/ gemcitabine combination chemotherapy has emerged as the reference first-line treatment regimen; there is no standard second-line therapy. Selected patients may be suitable for liver-directed therapy (e.g., radioembolization or external beam radiation), pending confirmation of benefit in randomized studies. Initial trials targeting the epithelial growth factor receptor and angiogenesis pathways have failed to deliver new treatments. Emerging data from next-generation sequencing analyses have iden- tified actionable mutations (e.g.,FGFR fusion rearrangements and IDH1 and IDH2 mutations), with several targeted drugs entering clinical development with encouraging results. The role of systemic therapies, including targeted therapies and immunotherapy for BTC, is rapidly evolving and is the sub- ject of this review. Significance: The authors address genetic drivers and molecular biology from a translational per- spective, in an intent to offer a clear view of the recent past, present, and future of BTC. The review describes a state-of-the-art update of the current status and future directions of research and therapy in advanced BTC. Cancer Discov; 7(9); 1–20. -
