Role of Biomedical Informatics in Translational Cancer Research

  1. 1. Cancer Clinical and Translational Informatics GoalsJoel Saltz MD, PhDChair Department of BiomedicalInformaticsEmory University
  2. 2. Center for Comprehensive Informatics 1. Methods for integrative analyses, disease sub- typing and development/targeting of treatments based on genetic, genomic, proteomic, epigenetic, tissue and in-vivo imaging information 2. Quantitative analysis of Radiology and Pathology imaging data. Tools and methods for extracting features from imaging data and for using features to optimize cancer subtyping, change detection, characterization of treatment response.
  3. 3. Integrative Biomedical Informatics AnalysisCenter for Comprehensive Informatics • Reproducible anatomic/functional characterization at fine Radiology level (Pathology) and Imaging gross level (Radiology) • High throughput multi- scale image “Omic” Patient segmentation, feature Data Outcome extraction, analysis of features Pathologic • Integration of Features anatomic/functional characterization with multiple types of “omic” information
  4. 4. Example: Brain Tumor -- Correlation of Pathology Features with Integrative “omics”Center for Comprehensive Informatics
  5. 5. Example Correlative Imaging ResultsCenter for Comprehensive Informatics • TP53 mutant tumors had a smaller mean tumor sizes (p=0.002) on T2-weighted or FLAIR images. • EGFR mutant tumors were significantly larger than TP53 mutant tumors (p=0.0005). • High level EGFR amplification was associated with >5% enhancement and >5% proportion of necrosis (p < 0.01). > 5% Necrosis
  6. 6. 3. Tools and methods for inferring clinical course,Center for Comprehensive Informatics treatment, comorbidities from electronic health record data • Electronic Health/Medical Record (EMR) systems contain rich information • EMR systems are generally not designed to support research studies – Data element structures, free text and value codes are not targeted at research queries – Not readily interoperable. Different sites may represent same or comparable data in different formats • Inferring precise and nuanced descriptions of disease, co- morbidities, course, treatment (e.g. eMERGE; follow on projects such as MH-GRID) • Integrate extracted/modeled electronic health record information with clinical trial and registry data
  7. 7. Electronic Health Record Extraction PipelineCenter for Comprehensive Informatics • O/R mapping • Value set mapping Extract Mapping Calculation of Emory configuration derived CDW variables (Cloned) (transform) Virtual data model Categorize Classify Identify • Events clinical numeric temporal • Observations events • Demographics data patterns • Attributes • Associations Extract Mapping UHC configuration (Staged)
  8. 8. Center for Comprehensive Informatics 4. Methods and tools for biomedical-friendly HPC/Big data analytics. Current HPC/large scale data tools and platforms are powerful but can be relatively difficult to use. 5. Methods for management and annotation of large scale “omics” datasets. 6. Research on powerful, flexible ergonomic security architectures. Architectures need to minimize overhead required for secure data management.
  9. 9. Center for Comprehensive Informatics
  10. 10. Center for Comprehensive Informatics 7. Learning health care system: – informatics driven highly customized two way communication with patients and providers, customized decision support – ability to generate and validate machine interpretable descriptions of health problems, co-morbidities – data analytics to examine relationships between detailed patient health care status, physician, patient decision making, health care quality, resource utilization, health care outcomes
  11. 11. Center for Comprehensive Informatics 8. Human computer interaction in coordination of research, clinical activities and decision support. Methods for coordinating activities of clinicians, clinical researchers, Radiologists, Pathologists, geneticists and basic scientists.
