Essential data variables for a minimum dataset for head and neck cancer trials and clinical research: HNCIG consensus recommendations and database.

The Head and Neck Cancer International Group (HNCIG) has undertaken an international modified Delphi process to reach consensus on the essential data variables to be included in a minimum database for HNC research. Endorsed by 19 research organisations representing 34 countries, these recommendations provide the framework to facilitate and harmonise data collection and sharing for HNC research. These variables have also been incorporated into a ready to use downloadable HNCIG minimum database, available from the HNCIG website. • A Delphi process achieved global consensus on key variables to use in a H & N cancer database. • Consensus was endorsed by 19 research organizations representing 34 countries. • This study presents a framework for harmonized data collection in Head & Neck cancer research.
