本文对食管癌高发区南澳县主要恶性肿瘤死亡率趋势进行了分析。食管贲门癌死亡率仍保持较高水平 ,粗死亡率为90 57/10万 ,中国标化死亡率为86 55/10万 ,与1970年～1987年资料相比较 ,食管贲门癌变化无统计学意义 ,男性甚至还在上升。食管贲门癌的死亡年龄普遍上移。对肝癌、胃癌和肺癌的时间趋势分析表明 ,肝癌死亡率基本保持恒定 ,胃癌呈现明显下降趋势 ,经分析认为可能与该地区胃癌分类没有包括贲门癌有关。肺癌虽有上升 ,但与全国肺癌死亡率大幅上升相比 ,幅度相对较小。
This article analyzed the main malignant tumor mortality trends in Nanao County, a high-incidence area of esophageal cancer. The mortality rate of esophageal and cardiac cancers remained at a relatively high level. The crude mortality rate was 9057 per 100,000. The standardized mortality in China was 86 55 per 100,000. Compared with the data from 1970 to 1987, there was no statistical difference in esophageal and cardiac cancers. Meaning, men are even rising. The age of death from esophageal and cardiac cancer has generally increased. Analysis of the time trends of liver cancer, gastric cancer, and lung cancer showed that the mortality rate of liver cancer remained basically constant, and gastric cancer showed a declining trend. It was analyzed that it may be related to gastric cancer classification in the area that does not include cardiac cancer. Although lung cancer has risen, it is relatively small compared with the significant increase in lung cancer mortality in the country.
