磁县是我国食管癌高发区之一,1973年建立了防治试点,1974年建立了肿瘤登记报告制度,1974～1982年共发生食管癌病人5138例,年平均发病率为124.15/10万。经过9年来的病因预防,发现该县食管癌发病率和死亡率均有下降的趋势,趋势检验P<0.001,发病率前4年和后5年、死亡率前9年和后5年比较均有显著差异,U检验P<0.01,且以山区下降更为明显。通过几年来的防治工作,我们初步看到了降低“两率”的现象,证实了我们的防治效果比较适当,但还需继续观察。
Cixian County is one of the high-incidence areas of esophageal cancer in China. It was established in 1973. In 1974, a cancer registration report system was established. From 1974 to 1982, a total of 5,138 cases of esophageal cancer occurred. The average annual incidence rate was 124.15/100,000. After 9 years of etiology prevention, the incidence and mortality of esophageal cancer in the county have been found to decrease. The trend test is P<0.001. The incidence rate is 4 years before and 5 years after, and the mortality rate is 9 years before and after 5 years. There was a significant difference, U test P <0.01, and the decline is more obvious in the mountains. Through the prevention and control work over the past few years, we have initially seen the phenomenon of reducing the “two rates” and confirmed that our control effect is more appropriate, but we must continue to observe.
