Cancer Epidemiology Cohorts


Overview

Cohort studies are one of the fundamental designs for epidemiological research. Cancer epidemiology cohorts are large observational population studies in which groups of people with a set of characteristics or exposures are prospectively followed for the incidence of new cancers and cancer-related outcomes. Data from cohort studies have helped researchers to better understand the complex etiology of cancer, and have provided fundamental insights into key environmental, lifestyle, clinical, and genetic determinants of this disease and its outcomes.

Funding Opportunities

NCI is currently sponsoring the following Funding Opportunity Announcement (FOA) to support the Cancer Epidemiology Cohort infrastructure:

  • Core Infrastructure and Methodological Research for Cancer Epidemiology Cohorts - expires May 8, 2020:
  • Hypothesis-based research questions using cohort data are expected to seek support through appropriate research project mechanisms, such as investigator-initiated Research Project Grant (R01External Web Site Policy) and Research Program Project (P01External Web Site Policy) mechanisms.
  • Limited meeting support is available to cohorts that participate in cancer epidemiology research consortia through R13 and U13 conference grant applicationsExternal Web Site Policy.

Other NIH-supported FOAs related to cohort studies include:

  • Notice of Intent to Publish a Funding Opportunity Announcement for New Epidemiology Cohort Studies in Heart, Lung, Blood, and Sleep Diseases and Disorders
  • Notice of Intent to Publish a Funding Opportunity Announcement for Continuation of Existing Grant Based Epidemiology Cohort Studies in Heart, Lung, Blood, Sleep Diseases and Disorders
  • Maintain and Enrich Resource Infrastructure for Existing Environmental Epidemiology Cohorts - expires October 11, 2018:

This list provides links to resources that may be of interest to cancer epidemiologists interested in or conducting cohort-based studies, but is not exhaustive.

Descriptive Information from Existing Cohort Studies

  • Cancer Epidemiology Descriptive Cohort DatabaseExternal Web Site Policy
    This searchable database contains descriptive information about existing cohorts, including study design, eligibility criteria, enrollment numbers, numbers of biospecimens, and numbers of cancer and other health outcomes.
  • Cancer Patient and Survivor Cohort Studies
    This list provides links to cancer survivor data resources identified during an EGRP-sponsored workshop held in 2011 that may be of interest to cancer epidemiologists, but is not exhaustive.
  • Biospecimen Resources for Population Sciences
    This list provides links to biospecimen resources that may be of interest to cancer epidemiologists, but is not exhaustive.
  • NCI Cohort Consortium
    The NCI Cohort Consortium is an extramural-intramural partnership formed by NCI to address the need for large-scale collaborations to pool the large quantity of data and biospecimens necessary to conduct a wide range of cancer studies. It includes investigators responsible for more than 40 high-quality cohorts involving more than 4 million people. The cohorts are international in scope and cover large, rich, and diverse populations. Investigators team up to use common protocols and methods, and to conduct coordinated parallel and pooled analyses.

NIH-Sponsored Data Repositories

  • Cancer Epidemiology Data Repository
    A centralized, controlled-access database, where Investigators can deposit individual-level de-identified observational cancer datasets.
  • Database of Genotypes and Phenotypes (dbGAP)External Web Site Policy
    The database of Genotypes and Phenotypes (dbGaP) was developed to archive and distribute the data and results from studies that have investigated the interaction of genotype and phenotype in Humans.
  • BioLINCCExternal Web Site Policy
    The National Heart, Lung, and Blood Institute's (NHLBI) centralized, controlled-access database, where Investigators can deposit and access datasets related to heart, lung and blood diseases.

Cohort-related Analytical Tools

  • Cohort MetaData RepositoryExternal Web Site Policy
    The Cohort Metadata Repository (CMR) is a tool that documents data harmonization across cohorts. Variables from each cohort can be searched and compared to determine if harmonization is possible. Once harmonization has occurred, the harmonized variables and the specifications used to create the variables are also documented in the CMR. The CMR contains only metadata (variable names, formats, codes, descriptions) and no individual-level data. For more information on the CMR and how to use it, watch our archived webinar, Introduction to the Cohort Metadata Repository (CMR): A Data Harmonization ToolExternal Web Site Policy.
  • Nested-Cohort Software PackageExternal Web Site Policy
    NCI's intramural Division of Cancer Epidemiology and Genetics (DCEG) has made available this software package for fitting Kaplan-Meier and Cox Models to estimate standardized survival and attributable risks for studies where covariates of interest are observed on only a sample of the cohort. Standard designs that can be handled by this software include the case-cohort and case-control studies conducted within defined cohorts. At this time, the software does not yet support nested case-control designs.
