To understand the trend of gastric cancer mortality based on the exploration of the death data from 1970 to 2004 in Zhaoyuan County.
The death data of 1970-1974 were collected from the first malignant tumor death survey of China, and the data of 1985-2004 were derived from the cancer registration network of Zhaoyuan. The appreciation indexes were crude mortality rate and standardized mortality rates by the percentages of Chinese population in 1982 and the percentages of world population in 1966.
The crude mortality rates in the five periods of 1970-1974, 1985-1989, 1990-994, 1995-1999, and 2000-2004 were 34.94, 44.34, 40.05, 48.73, and 40.18 per 100,000, respectively; the standardized mortality rates by Chinese population were 30.82, 30.35, 27.78, 31.63, and 20.10 per 100,000, respectively. The gastric cancer mortality remained stability from 1970 to 1999, however, the standardized mortality rate of gastric cancer in 2000-2004 declined by 34.8% compared with that in 1970-1974. The study also observed that the highest age-specific gastric cancer mortality, in the past 35 years, has been postponed by 10 years. And, the gastric cancer mortality ranked from top first to top three.
There is a decreasing trend for the incidence of stomach cancer and this might be associated with the changes of dietary consumption and pattern.
通过对招远县1970年至2004年死亡数据的探究,了解胃癌死亡率的变化趋势。
1970 - 1974年的死亡数据取自中国首次恶性肿瘤死亡调查,1985 - 2004年的数据来自招远市癌症登记网络。评价指标为粗死亡率以及按照1982年中国人口百分比和1966年世界人口百分比计算的标准化死亡率。
1970 - 1974年、1985 - 1989年、1990 - 1994年、1995 - 1999年以及2000 - 2004年这五个时间段的粗死亡率分别为十万分之34.94、44.34、40.05、48.73和40.18;按中国人口计算的标准化死亡率分别为十万分之30.82、30.35、27.78、31.63和20.10。1970年至1999年胃癌死亡率保持稳定,然而,2000 - 2004年胃癌标准化死亡率与1970 - 1974年相比下降了34.8%。该研究还观察到,在过去35年中,特定年龄组胃癌最高死亡率推迟了10年。并且,胃癌死亡率从排名第一降至排名前三。
胃癌发病率呈下降趋势,这可能与饮食消费和模式的变化有关。
