A powerful way to discover key genes with causal roles in oncogenesis is to identify genomic regions that undergo frequent alteration in human cancers. Here we present high-resolution analyses of somatic copy-number alterations (SCNAs) from 3,131 cancer specimens, belonging largely to 26 histological types. We identify 158 regions of focal SCNA that are(More)
UNLABELLED The success in lung cancer therapy with programmed death (PD)-1 blockade suggests that immune escape mechanisms contribute to lung tumor pathogenesis. We identified a correlation between EGF receptor (EGFR) pathway activation and a signature of immunosuppression manifested by upregulation of PD-1, PD-L1, CTL antigen-4 (CTLA-4), and multiple(More)
PURPOSE The anaplastic large cell kinase gene (ALK) is rearranged in approximately 5% of lung adenocarcinomas within the Asian population. We evaluated the incidence and the characteristics of ALK-rearranged lung adenocarcinomas within the western population and the optimal diagnostic modality to detect ALK rearrangements in routine clinical practice.

PURPOSE Erlotinib has proven activity in pretreated patients with advanced non-small cell lung cancer (NSCLC). We evaluated erlotinib in the frontline treatment of advanced NSCLC and assessed biological predictors of outcome. EXPERIMENTAL DESIGN In this phase II study, chemotherapy-naive patients with stage IIIB/IV NSCLC received oral erlotinib (150 mg/d)(More)
UNLABELLED While genomically targeted therapies have improved outcomes for patients with lung adenocarcinoma, little is known about the genomic alterations which drive squamous cell lung cancer. Sanger sequencing of the tyrosine kinome identified mutations in the DDR2 kinase gene in 3.8% of squamous cell lung cancers and cell lines. Squamous lung cancer(More)
Translating whole-exome sequencing (WES) for prospective clinical use may have an impact on the care of patients with cancer; however, multiple innovations are necessary for clinical implementation. These include rapid and robust WES of DNA derived from formalin-fixed, paraffin-embedded tumor tissue, analytical output similar to data from frozen samples and(More)
7514 Background: The anaplastic lymphoma kinase (ALK) fusion gene is a key oncogenic driver in a subset of NSCLC patients (pts). Crizotinib is a potent, selective, ATP-competitive, small molecule ALK inhibitor. Pts with ALK-rearranged NSCLC had a high response rate to crizotinib in a prior expanded cohort study. METHODS This ongoing study included pts(More)
INTRODUCTION Mutations in Ras family genes are rare in malignant mesothelioma. The role of activation of the Ras signaling pathway in the pathogenesis of mesothelioma is not clear. METHODS We studied the activation status of the Ras pathway and the status of other Ras-associated kinases in a panel of human mesothelioma cell lines. In addition, we tested(More)
Despite compelling antitumour activity of antibodies targeting the programmed death 1 (PD-1): programmed death ligand 1 (PD-L1) immune checkpoint in lung cancer, resistance to these therapies has increasingly been observed. In this study, to elucidate mechanisms of adaptive resistance, we analyse the tumour immune microenvironment in the context of(More)
Background MET expression and activation appear to be important for initiation and progression of triple-negative breast cancer. Tivantinib (ARQ 197) is an orally administered agent that targets MET, although recent preclinical data suggests the agent may have mechanisms of action that are independent of MET signaling. We conducted a phase 2 study of(More)
