Breast cancer incidence is increasing in the Gulf Cooperation Council (GCC) countries: Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and United Arab Emirates.
This study analysed geographical patterns, time trends, and age distribution of female breast cancer incidence among nationals and non-nationals in GCC countries.
Available cancer registry data for 1979-2016 were retrieved for the GCC countries. Age-standardized rates (ASRs) per 100 000 women were calculated using the World standard population. Comparisons were made by calculating comparative incidence figures.
From 1998 to 2012, incidence among nationals was highest in Bahrain (ASR 61.85), Kuwait (ASR 52.66), and Qatar (ASR 56.90) and lowest in Saudi Arabia (ASR 19.76), Oman (ASR 22.33), and United Arab Emirates (ASR 31.05). In the most recent period, data were available only in Qatar (2014-2016) and Saudi Arabia (2013-2015). Non-nationals and nationals in Qatar had higher incidence rates than in Saudi Arabia. Incidence among nationals in Qatar was at least twice that in Saudi Arabia (comparative incidence figure 2.32). Incidence among non-nationals in Qatar was 3 times higher than in Saudi Arabia. Among nationals in Kuwait, 10.8% of cases of breast cancer occurred in women aged < 40 years in 2008-2012, compared with 24.2% in non-nationals in Qatar in 2014-2016.
Breast cancer incidence has increased over time among women in most GCC countries, likely reflecting the improvements in healthcare access and screening programmes. Nationals and non-nationals developed breast cancer at a younger age than women in other high-income countries. Increased screening uptake is still required in the region. Evidence-based, locally-informed interventions should be implemented to address risk factors specific to the nationals and non-nationals in the GCC countries.
海湾合作委员会（GCC）国家（巴林、科威特、阿曼、卡塔尔、沙特阿拉伯和阿拉伯联合酋长国）的乳腺癌发病率正在上升。
本研究分析了GCC国家本国人和非本国女性乳腺癌发病率的地理模式、时间趋势和年龄分布。
检索了GCC国家1979 - 2016年可用的癌症登记数据。使用世界标准人口计算每10万名女性的年龄标准化率（ASR）。通过计算比较发病率数据进行比较。
1998年至2012年期间，本国人群中，巴林（ASR 61.85）、科威特（ASR 52.66）和卡塔尔（ASR 56.90）的发病率最高，而沙特阿拉伯（ASR 19.76）、阿曼（ASR 22.33）和阿拉伯联合酋长国（ASR 31.05）的发病率最低。在最近时期，只有卡塔尔（2014 - 2016年）和沙特阿拉伯（2013 - 2015年）有数据。卡塔尔的非本国人和本国人群的发病率高于沙特阿拉伯。卡塔尔本国人群的发病率至少是沙特阿拉伯的两倍（比较发病率数据为2.32）。卡塔尔非本国人群的发病率比沙特阿拉伯高3倍。在科威特本国人群中，2008 - 2012年10.8%的乳腺癌病例发生在40岁以下女性中，而在卡塔尔非本国人群中，2014 - 2016年这一比例为24.2%。
大多数GCC国家女性的乳腺癌发病率随时间有所上升，这可能反映了医疗保健可及性和筛查计划的改善。本国人和非本国人群患乳腺癌的年龄比其他高收入国家的女性更小。该地区仍需提高筛查的参与率。应实施基于证据且适合当地情况的干预措施，以应对GCC国家本国人和非本国人群特有的风险因素。
