In plain words
Using data from Iran's national cancer registry, this research showed that stomach cancer is more common in Iran than the world average. The type and location of stomach cancer are not the same across the country's provinces, and these differences may be linked to different factors in different regions. Most patients were men, and the most common tumour sites were the cardia (the top of the stomach) and the pylorus (the outlet of the stomach). More studies are needed to understand the causes of these differences.
Key results
Study population
Patients with stomach cancer recorded in the Iranian National Cancer Registry (INCR) during 2004 to 2014. Patients were predominantly men (49,907, 70.0%). Exact inclusion criteria are not stated in the abstract.
Endpoints
Crude and age-standardised incidence rates of stomach cancer in each province, and the frequency distribution of stomach tumour types and sites by province.
Safety and side effects
This is a descriptive epidemiological study and no treatment adverse events are reported.
Clinical significance and place in guidelines
This study is descriptive and makes no direct treatment recommendations. Its findings may be useful for health planning and for prioritising aetiological studies in the different provinces of Iran. Any use in guidelines or screening should be checked separately.
Limitations
According to the abstract, this study is descriptive and did not examine risk factors or the causes of provincial differences; the authors themselves stress the need for further studies to understand the epidemiology and aetiology. Other limitations (such as the quality and completeness of registry data) are not given in the abstract and should be checked in the full text.
