A Population-Based Cancer Registry (PBCR) was set up in Sikkim (a state in the North Eastern India) in 2003. We examined incidence rates by ethnic groups from 2003-2008.
Age-adjusted incidence rates (AARs) per 100,000 person-years were calculated by direct method using the world standard population, and analysed by ethnic group (Bhutia, Rai and other).
There were a total of 1148 male and 1063 female cases of cancer between 2003 and 2008 on the Sikkim PBCR. The overall AARs were 89.4 and 99.4 per 100,000 person-years in males and females, respectively. Incidence rates were highest amongst the Bhutia group (AAR=172.4 and 147.4 per 100,000 person-years in males and females, respectively), and the largest difference in rates were observed for stomach cancers with AARs being 12.6 and 4.7 times higher in the Bhutia group compared with other ethnic groups in males and females, respectively.
These observations call for further epidemiological investigations and the introduction of screening programmes.
2003 年，印度东北部的锡金邦建立了一个基于人群的癌症登记处（PBCR）。我们从 2003 年至 2008 年按族裔群体检查了发病率。
使用世界标准人口，直接法计算每 10 万人年的年龄调整发病率（AAR），并按族裔群体（不丹人、雷人和其他）进行分析。
2003 年至 2008 年，锡金 PBCR 共有 1148 名男性和 1063 名女性癌症病例。男性和女性的总体 AAR 分别为 89.4 和 99.4/100,000 人年。不丹族群的发病率最高（男性和女性的 AAR 分别为 172.4 和 147.4/100,000 人年），且观察到的发病率差异最大的是胃癌，不丹族群的 AAR 分别比其他族裔高出 12.6 和 4.7 倍。
这些观察结果呼吁进一步进行流行病学调查和引入筛查计划。
