Features of gastric cancer by anatomic subsite in northern China: A multi-center Health Science Report database study

Figure 1 Anatomical distribution of gastric cancer among the study population. A: All involved patients; B: Gastric cardia, body, and antrum.

Figure 2 Sex and age distribution among the different anatomical subsites of gastric cancer. A: Sex distribution for the three anatomical subsites; B: Sex distribution for the cardia and non-cardia cases; C: Age distribution for the three anatomical subsites; D: Age distribution for the cardia and non-cardia cancer cases.

Figure 3 Alternation trends in combined diagnosis, age, and constituent ratio according to the anatomical subsite of gastric cancer during the study period. A: Percentage change in cardia cancer along with the complication of gastroesophageal reflux disease; B: Percentage change in gastric antrum cancer along with the complication of Helicoibacter pylori (H. pylori) infection-related diseases; C: Age changes among patients with cardia cancer aged 50-74 years, after stratification of patients into five age subgroups; D: Age changes among patients with non-cardia cancer aged 50-74 years, after stratification into five age subgroups. GERD: Gastroesophageal reflux disease; HIRD: H. pylori infection-related diseases.

A: Validation of risk factors on in-hospital death through Poisson regression; B: Validation of risk factors on short-term postoperative complications through logistic regression.
