Epidemiologic studies on environmental and host-specific factors for human cancers

癌症流行病学的优先领域由4个分支组成：1)民族流行病学；分析流行病学；3)分子流行病学；4)临床流行病学。此外，大规模队列研究、分子流行病学和ATL研究三个促进委员会支持这一领域的研究计划。日本合作队列(JACC)研究始于1988年，在日本癌症的风险和保护因素方面产生了许多新的发现，并用血清流行病学证据对这些证据进行了评估。分子流行病学委员会建立了保存国家和国际人类样本和有效使用这些重要材料的标准系统。此外，其委员会在审议了伦理通信、问卷标准化、血样采集方法、长期保存人体材料等所有问题后，完成了建立日本多机构合作小组(J-MICC)标准手册。ATL研究促进委员会回顾了过去20年进行的流行病学、基础和临床研究，并提出了几个剩余的重要课题。应该传播从这个研究区域获得的现有信息，以预防日本癌症，因此，每年在东京和从北海道到九州区的其他城市举办两次公开研讨会。出版了对癌症预防有用的信息最后，从25个计划对象在五年内获得的所有信息都被汇集成几本名为《癌症预防的前沿》的书籍，并通过主页向公众开放。

The priority area of the cancer epidemiology were formed by 4 study branches : 1) ethnoepidemiology ; analytical epidemiology ; 3) molecular epidemiology ; 4) clinical epidemiology. Furthermore, three promoting committees of large-scaled cohort study, molecular epidemiology and ATL research, supported the study programs in this area. The Japan Collaborative Cohort (JACC) study started from 1988 generated many new findings on risk and protective factors of Japanese cancer and these evidences were evaluated by seroepidemiological evidences. The committee of molecular epidemiology established a standard system for reservation of national and international human samples and effectual usage of these important materials. Furthermore its committee completed a standard manual for establishment of the Japanese Multi-institutional Collaborative Cohort (J-MICC) after deliberating all issues of ethical correspondence, standardization of questionnaire, collecting methods of blood samples, long-term reservation of human materials. The promoting committee of ATL research reviewed epidemiologic, basic and clinical studies conducted in the last 20 years and suggested several remaining and important subject. Available information obtained from this study area should be disseminated to prevent Japanese cancer, therefore, public symposia were organized twice a year in Tokyo and other cities from Hokkaido to Kyushu district. published useful information for cancer prevention Finally all information obtained from 25 planned subjects in five years were brought together into a couple of books entitled the forefront of cancer prevention" and also opened to the public by home page.
