Bladder cancer is a common cancer in the world with the highest rates in Southern and Western Europe, North America, and Western Asia. It imposes a high economic burden to the health care system globally. The objective of this study is to provide the incidence of bladder cancer and its geographic distribution in Iran in 2014, 2015 and 2016.
We registered 5817, 5662 and 6630 new bladder cancer cases in 2014, 2015 and 2016, respectively with men counting 82% of cases in every year. The ASR of bladder cancer in total Iranian population was 8.50 (95% CI: 8.28-8.72), 8.05 (95% CI: 7.83-8.27) and 8.74 (95% CI: 8.52-8.96) per 100,000 in those years. The male to female ratio was 5 every year. Kerman has the highest ASR in each of the years, respectively 15.49, 13.07 and 12.46, and Ilam has the lowest ASR during 2014 to 2015, respectively 4.27 and 3.50, and Sistan and Baluchestan has the lowest rate in 2016 (ASR:3.56) in both sexes.
The highest incidence of bladder cancer was observed in Central, southern and northwestern parts of Iran. Through the analysis of the incidence patterns and the identification of risk factors associated with it, steps can be taken towards prevention and control measures.
膀胱癌是世界上常见的癌症，在欧洲南部和西部、北美洲和西亚的发病率最高。它给全球的医疗保健系统带来了沉重的经济负担。本研究的目的是提供 2014 年、2015 年和 2016 年伊朗膀胱癌的发病率及其地理分布。
我们分别在 2014 年、2015 年和 2016 年登记了 5817 例、5662 例和 6630 例新膀胱癌病例，每年男性病例占 82%。伊朗总人口膀胱癌的 ASR 分别为 8.50（95%CI：8.28-8.72）、8.05（95%CI：7.83-8.27）和 8.74（95%CI：8.52-8.96）/100000。男女性别比为 5 比 1。每年克尔曼的 ASR 最高，分别为 15.49、13.07 和 12.46，而伊拉姆在 2014 年至 2015 年的 ASR 最低，分别为 4.27 和 3.50，而锡斯坦和俾路支省在 2016 年的男女两性发病率最低（ASR：3.56）。
伊朗中南部和西北部地区膀胱癌的发病率最高。通过分析发病率模式和确定与之相关的危险因素，可以采取措施进行预防和控制。
