Few countries in the Middle East have a population-based cancer registry, despite a clear need for accurate cancer statistics in this region. We therefore established a registry in the East Azerbaijan province, the sixth largest province in northwestern Iran.
We actively collected data from 20 counties, 62 cities, and 44 districts for the period between 20 March 2015 and 19 March 2016 (one Iranian solar year). The CanReg5 software was then used to estimate age-standardized incidence rates (ASRs) per 100,000 for all cancers and different cancer types.
Data for 11,536 patients were identified, but we only analyzed data for 6655 cases after removing duplicates and non-residents. The ASR for all cancers, except non-melanoma skin cancer, was 167.1 per 100,000 males and 125.7 per 100,000 females. The most common cancers in men were stomach (ASR 29.7), colorectal (ASR 18.2), bladder (ASR 17.6), prostate (ASR 17.3), and lung (ASR 15.4) cancers; in women, they were breast (ASR 31.1), colorectal (ASR 13.7), stomach (13.3), thyroid (ASR 7.8), and esophageal (ASR 7.1) cancers. Both the death certificate rate (19.5%) and the microscopic verification rate (65%) indicated that the data for the cancer registry were of reasonable quality.
The results of the East Azerbaijan Population-based Cancer Registry show a high incidence of cancer in this province, especially gastrointestinal cancers.
尽管中东地区对癌症统计数据的准确性有明确需求，但很少有国家建立基于人群的癌症登记处。因此，我们在伊朗西北部第六大省东阿塞拜疆省建立了一个登记处。
我们从 2015 年 3 月 20 日至 2016 年 3 月 19 日（伊朗一个太阳年）期间，积极从 20 个县、62 个城市和 44 个区收集数据。然后使用 CanReg5 软件估计所有癌症和不同癌症类型的年龄标准化发病率（ASR）。
共确定了 11536 名患者的数据，但在去除重复和非居民数据后，我们仅分析了 6655 例患者的数据。除非黑色素瘤皮肤癌外，所有癌症的 ASR 为男性每 10 万人 167.1 例，女性每 10 万人 125.7 例。男性最常见的癌症是胃癌（ASR 29.7）、结直肠癌（ASR 18.2）、膀胱癌（ASR 17.6）、前列腺癌（ASR 17.3）和肺癌（ASR 15.4）；女性最常见的癌症是乳腺癌（ASR 31.1）、结直肠癌（ASR 13.7）、胃癌（ASR 13.3）、甲状腺癌（ASR 7.8）和食管癌（ASR 7.1）。死亡证明率（19.5%）和显微镜验证率（65%）均表明癌症登记处的数据质量合理。
东阿塞拜疆人群癌症登记处的结果显示该省癌症发病率较高，尤其是胃肠道癌症。
