NCI Gene-Environment Think-Tank

On this page...
Overview
Risk of cancer is determined by a complex interplay of genetic and environmental factors. Genome-wide association studies (GWAS) have identified hundreds of genetic variants associated with cancer. However, it remains unclear how to best incorporate gene-environment interplay into study design and analysis in order to better understand cancer etiology, or to identify public health interventions.
NCI's Epidemiology and Genomics Research Program (EGRP) sponsored a Gene-Environment Think-Tank on January 10-11, 2012 in Rockville, MD.

Leah Mechanic, PhD, MPH
Program Director, Genomic Epidemiology Branch

The objective was to facilitate discussions on the:
- goals of gene-environment interaction studies in cancer epidemiology;
- state of the science of gene-environment interactions; and
- opportunities for the future, including novel study design and analysis tools.
Topics covered included presentations on summary results from large consortia studies of breast, lung, colon, and bladder cancer; review of current statistical methods; and discussion of challenges in the field.
