A rising trend of gastric cardia cancer in Gansu Province of China.

We evaluated the incidence, age, gender, and anatomical distribution of gastric cancers in 65,284 cases of upper GI endoscopies. A total of 5253 gastric cancer cases were identified. Cancers of the cardia, fundus, body and antrum account for 33.6%, 2.7%, 23.6% and 34.0% of all cases, respectively. The mean age for gastric cancers was 56.9+/-10.2 years and 69.7% of the cancer cases were found in the 50-69 year age group. Subjects with cardia cancer were slightly older than subjects with non-cardia cancer. Over the 12-year period, the incidence of the gastric antrum cancer had significantly declined, whereas the incidence of the gastric cancer in the cardia and body had risen steadily. Thus, there was a rising trend of cardia cancers and a decreasing trend of most non-cardia cancers.
