title: [Study on geographic characteristics of malignant tumors in digestive system in Shanxi province].
abstract: The mortality of esophageal, stomach and hepatic cancers occupied 70% among all who died from cancers in Shanxi province. Countries which had the highest mortality of the above three kinds of cancers showed significant aggregation. Differences between countries with higher and lower mortality were obvious. The annual mean temperature and rainfall decreased with the raise of latitude in Shanxi province. So was found the mortality of these cancers. Both of them tended to be coincident, and the difference was statistically significant (P < 0.05). These results were not in agreement with reports from foreign countries which need to be further studied.
