To analyze the incidence of digestive system cancer in Changle of China over a 15-year period.
The datasets were presented as time-series of China-standardized annual incidence during 1988-2002. Linear regression model was used to analyze the incidence of stomach, liver, esophagus and colorectal cancers.
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).
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.
分析中国长乐地区15年间消化系统癌症的发病率。
数据集呈现为1988 - 2002年中国标准化年发病率的时间序列。采用线性回归模型分析胃癌、肝癌、食管癌和结直肠癌的发病率。
男性和女性胃癌及食管癌发病率时间序列的线性回归模型具有统计学意义(P < 0.05);男性肝癌和结直肠癌的回归模型具有统计学意义(P < 0.05)。
男性和女性胃癌及食管癌的发病率均呈下降趋势。男性中,肝癌发病率呈下降趋势,结直肠癌发病率呈上升趋势。
