结直肠癌是亚洲第四大常见癌症。然而，尚未分析亚洲国家结直肠癌发病率的亚中心趋势。我们使用来自6个癌症登记处的最新高质量数据，1998-2002年和2003-2007年，来自五大洲癌症发病率，以估计5个亚洲国家的结直肠癌发病率。具有重叠病变或其他未指明的结肠癌的病例被重新分配为近端或远端结肠癌。计算了每个子站点1998 - 2002年至2003-2007年的每10万人口的标准化发病率（ASR）和发病率比率。2003-2007年，日本宫城的男性在近端结肠、远端结肠和直肠中的癌症ASR最高。以色列犹太血统的男性近端和远端结肠癌的ASR较高，但直肠癌的ASR最低。直肠癌的比例在韩国男性中最高（51.39%），在以色列女性中最低（26.6%）。从1998-2002年到2003-2007年，除了日本宫城的男性和韩国的男性外，大多数登记处的直肠癌发病率没有显著变化。然而，在同一时期，近端和远端结肠的癌症发病率在大多数登记中增加。总之，亚洲登记研究中结直肠癌的亚部位分布存在显著差异，结直肠癌总体发病率的增加可归因于结肠癌的增加。(C)2016爱思唯尔有限公司版权所有。
Colorectal cancer is the fourth most common cancer in Asia. However, the trends in colorectal cancer incidence by subsite have not been analyzed across Asian countries. We used the most recent, high quality data from 6 cancer registries for two 5-year periods, 1998-2002 and 2003-2007, from Cancer Incidence in Five Continents to estimate colorectal cancer incidence by subsite in 5 Asian countries. Cases with overlapping lesions or otherwise unspecified colon cancer were re-distributed as proximal or distal colon cancer. Age-standardized incidence rates (ASRs) per 100,000 population and incidence rate ratios from 1998 to 2002 to 2003-2007 were calculated for each subsite. For 2003-2007, men in Miyagi, Japan, had the highest ASR for cancer in the proximal colon, distal colon and rectum. Men of Jewish ancestry in Israel had a high ASR for proximal and distal colon cancer, but the lowest ASR for rectal cancer. The proportion of rectal cancer was highest among Korean men (51.39%) and lowest among Israeli women (26.6%). From 1998-2002 to 2003-2007, rectal cancer incidence did not significantly change in most registries, except for men in Miyagi, Japan, and both sexes in Korea. However, during the same period cancer incidence in the proximal and distal colon increased in most registries. In conclusion, there was substantial variation in subsite distributions of colorectal cancer in Asian registries and increases in overall incidence of colorectal cancer could be attributed to increases in colon cancer.
