Burden of five major types of gastrointestinal cancer in the Eastern Mediterranean Region.

[OBJECTIVE] We provide an overview of the latest estimates of five gastrointestinal (GI) cancers in the Eastern Mediterranean Region (EMR) countries to guide cancer control policy.

[METHODS] We extracted the number of cases and deaths for oesophageal, gastric, liver, colorectal and pancreatic cancers from the GLOBOCAN database produced as estimated by the International Agency for Research on Cancer for the year 2022. Age-standardised incidence and mortality rates (ASR) per 100 000 person-years were estimated for the 22 EMR countries, cancer site and sex.

[RESULTS] The estimated 173 000 new cancer cases and 139 000 deaths from the five GI cancers corresponded to 22.2% of the incidence and 28.7% of the mortality burden in the EMR. Across all cancers (for both sexes combined), colorectal cancer ranked third (6.9%; ASR 8.9), followed by liver cancer (6.2%; ASR 8.4) in terms of incidence, while liver cancer (9.6%; ASR 8.1) and gastric cancer (6.4%; ASR 5.5) were the third and fourth leading causes of cancer-related mortality in the region, respectively. Marked differences in cancer incidence and mortality rates were observed between the 22 countries, particularly the 10-fold variations seen in liver cancer incidence.

[CONCLUSION] GI cancers currently account for an important fraction of the cancer burden in the EMR; the present analysis seeks to inform tailored decision-making according to the country-specific GI cancer profiles.
