General introduction
 Descriptive epidemiology of gastric cancer
Global estimate: incidence and mortality
The Global Burden of Cancer Study (GLOBOCAN 2008)(18) provides the most recent figures available for the worldwide cancer burden with 988,000 new gastric cancer cases accounting for 7.8% of the total global cancer burden. This makes gastric cancer the fourth most prevalent global cancer after lung cancer (1.68 million cases; 12.7% of all cancers), breast cancer (1.31; 10.9%), and colorectal cancer (1.24; 9.8%). More than 73% (728,000 cases) of gastric cancer cases occur in parts of Asia, and almost half the world’s total (47%) of gastric cancer occurs in China (Fig. 2). Europe contributes nearly 15% of to the global burden (146,000 cases) of gastric cancer, whereas Central and South America add a further 7% (65,000 cases) (see Fig. 2).
