Complete the eDelphi Survey

Round 2 of the international GASTROS Delphi survey is now open. 

We are developing a core outcome set for gastric cancer surgery trials. We are asking surgeons, cancer nurses and patients from around the world to tell us which outcomes are most important to them through an online survey. Round 2 of the Delphi survey opened on the 28th of July 2019 and is available for those who completed round 1 of the survey. Instructions on how to complete round 2 have been emailed out to participants. If you would like any information or require troubleshooting support, please contact the study team on
