Abstract 923: The cBioPortal for Cancer Genomics: An intuitive open-source platform for exploration, analysis and visualization of cancer genomics data

Abstract The cBioPortal for Cancer Genomics is an open source software platform that enables interactive, exploratory analysis of large-scale cancer genomics data sets. It integrates genomic and clinical data, and provides a suite of visualization and analysis options, including cohort and patient-level visualization, mutation visualization, survival analysis, alteration enrichment analysis, and network analysis. The user interface is user-friendly, responsive, and makes genomic data easily accessible to scientists and clinicians. The public site (http://www.cbioportal.org) hosts data from more than 165 studies, including data from large consortia (TCGA and ICGC) and individual labs. With newly released functionality, users can now explore and query these studies individually or can combine multiple studies into new “virtual studies”. The main features of the portal include OncoPrints, a compact graphical representation of alterations in multiple genes across a cohort, mutational diagrams that show locations and frequencies of mutations in a single gene, Kaplan-Meier survival curves, plots that allow the visualization of correlation between different data types for a single or multiple genes (e.g. the correlation between DNA copy number and mRNA expression), among others. To facilitate interpretation of genomic data, the cBioPortal also now integrates annotations from several leading knowledgebases (OncoKB, CIViC, MyCancerGenome and COSMIC), as well as other resources that can guide variant interpretation (CancerHotspots, MutationAssessor, SIFT and PolyPhen). The cBioPortal has been widely adopted by the cancer community, with dozens of private instances at academic institutions and pharmaceutical/biotechnology companies. The public portal is currently accessed by approximately 25K unique visitors per month. Another notable instance is the cBioPortal for AACR GENIE (http://www.cbioportal.org/genie/), which hosts 31,706 samples from AACR Project GENIE. The cBioPortal is fully open source and all code is available on GitHub (https://github.com/cBioPortal/) under a GNU Affero GPL license. Development is a collaborative effort among groups at Memorial Sloan Kettering Cancer Center, Dana-Farber Cancer Institute, Children's Hospital of Philadelphia, Princess Margaret Cancer Centre, and The Hyve, an open source bioinformatics company based in the Netherlands. Ongoing development efforts are focused on (1) building the open source community; (2) implementing architectural and performance improvements; (3) expanding user support, documentation and training resources; (4) developing novel features to support immunogenomics and immunotherapy; (5) enhancing visualization of patient timelines, multiple tumor profiles, and cohort response; and (6) releasing a new public Application Programming Interface (API).
