Complete the eDelphi Survey

The international GASTROS Delphi survey is now open to patients, oncology nurses and surgeons! 

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. There are 8 language versions of the survey to allow as many participants as possible to complete it.

We would be grateful if you could inform colleagues and patients who may be interested in participating as well.
