METHODS： The datasets were presented as timeseries of China-standardized annual incidence during 1988-2002. Linear regression model was used to analyze the incidence of stomach, liver, esophagus and colorectal cancers. RESULTS： Linear regression models for the time-series of stomach and esophagus cancer incidences for both men and women were statistically significant （P 〈 0.05）; Regression models for liver cancer and for colorectal cancer were statistically significant for men （P 〈 0.05）. CONCLUSION： The incidence rates of stomach and esophagus cancers for both men and women had down tendencies. For men, liver cancer had a down trend of the incidence and colorectal cancer had an upward trend of the incidence rate.展开更多
