Hypothesis
The aetiological factors for adenocarcinoma of the cardia and pyloric antrum are different.
Conclusion
While the overall incidence of gastric carcinoma is decreasing, adenocarcinoma of the oesophagus and cardia is on the rise.
Supporting Evidence
- The incidence of distal gastric lesions is decreasing while adenocarcinoma rates are increasing.
- Endoscopy usage has increased significantly since the 1970s, affecting diagnosis rates.
- Social class distribution shows higher rates of cardia cases in professional classes.
Takeaway
More people are getting a specific type of stomach cancer called adenocarcinoma, even though overall stomach cancer rates are going down.
