摘　　要：本文报道了改良饮水对肝癌的预防效果,结果提示:改饮池塘水为深井水3年以上居民其肝癌发病率下降,较未改水前差异有高度显著性(P<0.01);改水8年以上者肝癌发病有可信的下降趋势(P< 0.01)。改水的年数越长,平均发病年龄越大,初步看到改水对肝癌发病有预防效果。本研究提示肝癌高发区居民改饮地下深井水是必要的,为现场进行干预试验提供了科学依据。This paper reported that three years after the habit of population in water drinking was changed from pond water to deep well water, the incidence rate of primary hepatocellular cancer decreased significantly. The difference was statistically significant (P<0.01). After eight years observation, there was a confident decrease tendency (P<0.01). The longer tLhe time of water improvement, the older the average hepat-oma onset age would be. Therefore, in the high risk areas of hepatic cancer, the change of drinking habit to deep well water should be important.
