The current and future cancer burden in the Gulf Cooperation Council (GCC) countries

Background: Cancer is a leading cause of morbidity and mortality in the Gulf Cooperation Council (GCC) countries. This study aims to provide cancer incidence and mortality estimates in 2020 in the GCC countries alongside future projections for 2040 to shape cancer control policy in the region. Methods: The estimated numbers of new cancer cases and deaths were extracted from the GLOBOCAN database developed by the International Agency for Research on Cancer; new cancer cases, cancer deaths, and corresponding age-standardized incidence and mortality rates for the year 2020 are presented. Results: An estimated 42,475 new cancer cases and 19,895 deaths occurred in the GCC countries in 2020, with corresponding age-standardized incidence and mortality rates of 96.5 and 52.3 per 100,000, respectively. Female breast (16%), colorectal (13%), and thyroid (9%) were the most common types of cancer in the GCC countries, accounting for almost 40% of all cancer incidence. Colorectal (14%) followed by breast cancer (9%) were the leading causes of cancer death, though the magnitude of rates of the major cancer types varied substantially across the GCC countries. Even if we assume rates in the region will remain unchanged over the next two decades, the cancer burden in the GCC will increase by 116% (Saudi Arabia) to 270% (Qatar), reaching nearly 104,000 cancer cases by the year 2040. Conclusion: The sharp increase in the estimated cancer incidence and mortality predicted over the next decades in the region requires workforce and financial planning for the healthcare systems in the constituent countries, alongside broader strengthening of national cancer prevention and control efforts.
