Hypothesis
The study aims to describe the trend of gastric cancers by location in Iran.
Conclusion
The study found an increasing prevalence of upper and middle third gastric adenocarcinomas and a decrease in the lower third over 36 years.
Supporting Evidence

- The decrease in lower third gastric cancers was noted across both sexes and age groups.
- The study suggests different risk factors may be contributing to these trends.
