| Abstract: |
| 本文以回顾性定群研究,报道了饮水与肿瘤的关系。研究结果提示:饮用水污染不仅与肝癌发病率有关,而且与胃癌、食管癌的发病率也有关系。改饮深井水后居民的肝癌、胃癌和食管癌发病率(死亡率)都有所下降。改饮深井水四年半以上的,居民肝癌死亡率,明显低于饮河水居民的肝癌死亡率,有显著差异(P﹤0.05)。因而我们认为继续深入探索饮水中的致癌物质,揭示饮水与肿瘤发病的内在联系,很有必要。本次研究结果,为我们在肝癌高发区努力改善居民饮用水条件,防止污染,以达到降低肿瘤发病率以及其他肠道病的流行,提供了理论依据。 |

| This paper reportes the relationship between the drinking water and cancer by using the method of retrospective-cohort study. The results indicate that the contamination of drin-king water is not only related with morbidity of liver cancer, but also with morbidity of stomach cancer and esophageal cancer. Recently, in view of that the population transformed the drinking river water to high deep well water and then. The morbidity of liver stomach and esophageal cancers were slowlly falling down. After 4.5 year's observation, a comparison between the population of drinking high deep well water and control group, was made the mortality of liver cancer of the former was more decreased than the laster. There is a statistical significant difference (P﹤0.05) between there two groups. Therefore in the high risk areas of liver cancer, drinking detter water should be necersary. |
