Epidemiologic Characteristics of Malignant Neoplasms in Taiwan: Ⅲ. Stomach Cancer

台灣地區惡性贅瘤之流行病學特徵:Ⅲ.胃癌

摘要


本研究以台灣地區1954~1983年胃癌死亡率及1983~1985年胃癌發生率資料,描述胃癌在台灣地區之長期趨勢,年齡,性比例及地理分佈特徵,並進行國際及移民比較。 台灣地區胃癌死亡率及發生率皆有隨年齡增加而呈現對數增加之趨勢,高年齡層之胃癌死亡率也最高。男性各年齡層之死亡率及發生率皆約爲女性的2倍。自1970年代開始,男、女性年齡標準化死亡率皆有逐漸下降之趨勢。 在17個國家及地區中,台灣男、女性胃癌,累積死亡率分別佔第11位及第13位。高死亡率地區大多集中在台灣東北部及東部及山地鄉鎮。移民比較發現,美國華人的胃癌發生率遠比上海、新加坡、台北及香港的華人爲低。

Mortality rates from 1954 to 1983 and incidence rates from 1983 to 1985 of stomach cancer in Taiwan were analyzed to examine its secular trend, age curve, sex ratio, geographical clustering, international variation and migrant difference. Both mortality and incidence rates of stomach cancer increased with age in a log-linear relationship and peaked at the highest age group. The sex (male-to-female) ratio remained consistently around two-fold for age-specific mortality and incidence rates. The age-adjusted mortality has been decreasing since early 1970s for both males and females. Among 17 countries and areas compared, cumulative stomach cancer mortality in Taiwan ranked as the 11th and 13th, respectively, for males and females. High stomach cancer mortality rates were found to cluster in northeastern area and eastern aboriginal townships in Taiwan. Migrant study showed that Chinese in United States had much lower stomach cancer incidence than those in Shanghai, Singapore, Taipei and Hong Kong.
