中文摘要：

背景与目的：癌症严重威胁人类健康和社会经济发展,是我国及全球主要的公共健康问题。该研究旨在探讨多种癌症在我国不同地区的分布特征及与癌症患病率之间的关系,为癌症预防和管理提供科学依据。方法：数据来源为2012年军事医学科学院出版的《中国癌症发病与死亡2003—2007》,收集全国32个地区的2003—2007年不同性别人群的23种癌症发病率资料,采用对应分析获得不同地区的癌症分布特征,采用聚类分析将相同特征的癌症与地区聚为一类,可获得多个有特殊意义的分类。结果：食管癌、胃癌、肝癌、肺癌和结直肠与肛门癌均是男、女性高发病种。所有分组资料的食管癌和胃癌高发区涉县、阳城县、林州市、盐亭县、扬中市和建湖县等地区常聚为一类;扶绥县属于多种癌症发病率低于全国平均水平而肝癌高发区,在男性和合计发病率资料中单独聚为一类;广州市、四会市和中山市属于男、女性鼻咽癌高发区;启东市和海门市等农村地区属于肝癌高发区,在合计和男性发病率资料中聚为一类;结直肠与肛门癌和女性乳腺癌聚为一类,属于城市地区高发病种;女性子宫颈癌属于发病率仅次于消化系统癌症、肺癌和乳腺癌的高发病种。结论：聚为同一类的食管癌高发区涉县、磁县和阳城县等地区和聚为同一类的其他地区或癌症可能存在共同的致癌因素。

英文摘要：

Background and purpose： Cancer is a major public health issue in China and worldwide, which seriously threatens human beings as well as social and economic development. This study explored the relationships between the cancer distribution characteristics and cancer prevalences in Chinese cancer surveillance regions to provide scientific evidence for cancer prevention and management. Methods： The data were obtained from the book named ＂Prevalence and Mortality of Cancer in China from 2003-2007＂ including incidence of 23 cancer types in 32 regions of China published by the Academy of Military Medical Sciences of the Chinese PLA in 2012. Correspondence analysis was used to gain the relation between the prevalence and area distribution. Cluster analysis was used to obtain the classifications with special significance by putting the cancers or regions with similar characteristics into a cluster. Results： Esophageal cancer, gastric cancer, liver cancer, lung cancer, colorectal and anal cancer have high incidence and mortality in both genders. The districts with high incidence of esophageal cancer and gastric cancer were grouped together. The counties or cities （Shexian, Yangcheng, Linzhou, Yanting, Yangzhong and Jianhu） with high incidence of esophageal cancer and gastric cancer were classified into same cluster frequently. Fusui was grouped along because of the lower incidence of various cancers than the national average except for liver cancer. Guangzhou, Sihui and Zbongshan were the districts with high incidence of nasopharyngeaJ carcinoma in both genders. Rural areas in Qidong and Haimen were classified into a vluster in male and Iolal dala for the high incidence of liver cancer. Colorectal eanver, anal eaneer and breast cancer in women also had high incidence in urban areas. Cervical cancer had the seeond level high incidence in women fnllowing diseases of digestive system, breast cancer and hmg cancer. Conclusion： Similar pathogenie fae, tors may exist in counties or cities of Shexian, Cixian, Yan
