ABSTRACT:

Background

The current AJCC staging system for gastric cancer (AJCC7) incorporated several major revisions to the previous edition.

The International Gastric Cancer Association (IGCA) launched a project to support evidence-based revisions to the next edition of the AJCC staging system.
