About Us

The Stomach cancer Pooling (StoP) Project is a consortium of epidemiological studies of gastric cancer. 

The project started in July 2012, based on a core group of 10 studies. Several investigators joined the project during the last 5 years, and the consortium now counts over 30 studies from different world areas.

The main aim of the StoP Project is to examine the role of several lifestyle and genetic determinants in the aetiology of gastric cancer, through pooled analyses of individual-level data, after central collection and validation of the original datasets.

 

=== NEW! ===     V. 3.0 of the StoP Project harmonized database has been released, including 33 studies and a total of 12,753 cases and 30,682 controls
