Jiangsu Four Cancers Study: a large case-control study of lung liver stomach and esophageal cancers in Jiangsu Province China

摘要

Objective:Cancer is a major public health burden both globally and in China. The most common cancer-related deaths in China are attributable to cancers of the lung, liver, stomach, and esophagus. Previous epidemiologic studies on cancer in China have often been limited by small sample sizes, inconsistent measurements, and lack of precise and accurate data. The Jiangsu Four Cancers (JFC) Study is a population-based case-control study conducted in an effort to obtain consistent and high quality data to investigate the life style, behavioral, environmental, and genetic factors associated with the four major cancers in China. The objective of this paper is to describe the overall design of the JFC Study and report selected findings on the major risk factors of cancers.
