Workshop to Facilitate Cancer Systems Epidemiology Research

Workshop to Facilitate Cancer Systems Epidemiology Research, February 28 – March 1, 2019, Bethesda, MD

Overview

The availability of high throughput -omic technologies, novel devices for exposure assessment, and electronic medical records have the potential to facilitate a more comprehensive study of risk factors contributing to development of and outcomes from cancer.

Despite individual successes at identifying genetic, biological, and environmental risk factors for cancer, much of the etiology remains unexplained. This may be due in part to the limited focus of many studies on a single or small set of risk factors or data types (i.e. measures such as DNA sequence, methylation data, variables from questionnaires). Moreover, many studies fail to consider the complexities and interrelations among multiple risk factors and associated outcomes. For example, each individual risk factor, such as a single dietary component or genetic polymorphism, occurs in a broader biological (e.g. pathways) or societal (e.g. individual in social network) context which could modulate the effect of individual risk factors on disease. Further, many risk factors for disease can be highly correlated with possible interactive, synergistic, or attenuating effects. Importantly, risk factors can change over time.

Cancer Systems Epidemiology Insights and Future Opportunities

A collection of seven papers that highlight findings based on systems epidemiology approaches and opportunities for the future. This collection stems from discussions during NCI’s 2019 Workshop.

A more comprehensive, systems modeling based type of approach, which accounts for multiple dimensions, integration of diverse data types, and changes over time, is needed to better understand contributors to disease and treatment outcomes and provide clues for improved intervention.

Purpose

The objective of this workshop was to facilitate interdisciplinary discussion about the application of systems modeling approaches for population-based cancer epidemiology research. By bringing together scientists from various fields that use systems modeling the workshop aimed to:

  • Identify ideas and strategies to improve understanding of systems modeling among population scientists and epidemiology amongst modelers;
  • Share lessons learned in the application of systems approaches from other fields (e.g. cancer biology)
  • Identify of potential high-impact use cases for systems modeling in population science;
  • Increase understanding of potential barriers and facilitators to taking a system modeling approach in population science (including dataset availabilities, data and methods needs)
  • Establish new collaborative interdisciplinary relationships between statisticians, mathematicians, computer scientists, bioinformaticians, epidemiologists, and clinicians.
