摘要

研究目的: 利用絕對與相對指標按不同年代及年齡層進行肺腺癌發生率的性別比較。
研究方法: 資料來源自世界衛生組織(World Health Organization, WHO)的國際癌症研究機構(International Agency for Research on Cancer, IARC)出版的 Cancer Incidence in Five Continents 第六至第八版、台灣行政院衛生署癌症登計系統提供肺腺癌的發生資料，共18個國家。分析年代有1983-1987年和1993-1997年。計算肺腺癌直接年齡標準化發生率與年齡別(30-44、45-64、65-79)發生率，及分析不同年齡層、不同年代之肺腺癌發生率之年齡與年代增加率，進一步利用Poisson 迴歸計算相對危險性及其95%信賴區間(95% confident interval, 95%CI)。
結果: 1983-1987年台灣肺腺癌年齡標準化發生率男性每十萬人口為4.94人、女性3.05人， 1993-1997年男女性分別為8.27人、6.52人，其餘國家除了冰島外都呈現男性肺腺癌發生率高於女性，且大多數國家性別比隨年代增加而下降。以30-44歲當做基線(baseline)，在1983-1987年於45-64歲台灣男性肺腺癌發生率之年齡增加率為965.12%、女性622.31%，65-79歲男女性分別為2468.22%、1279.34%，除了1983-1987年的印度和西班牙外，其餘國家皆為男性年代增加率高於女性。相反地，台灣肺腺癌年齡標準化發生率之男性年代增加率為67.41%、女性113.77%，國家於不同年齡層女性增加率大多高於男性。
結論: 於絕對性比較，女性比起男性無較高罹患肺腺癌的危險性；相對性比較中，於年代效應，女性有較高罹患肺腺癌之相對危險性。於年齡效應，男性有較高罹患肺腺癌之相對危險性。

Objective: The purpose of this study was to determine the gender comparison of lung adenocarcinoma for different age groups and period by use of absolute and relative index. Methods: Data was obtained from the IARC (International Agency for Research on Cancer) of the World Health Organization(WHO) the publication Cancer Incidence in Five Continents sixth to the eighth edition and the Taiwan Department of Health Cancer registration system provides total incidence of lung adenocarcinoma data, totally 18 countries(1983-1987 and 1993-1997). We calculated the directly age-standardized incidence rate (ASIR) of lung adenocarcinoma, age (30-44, 45-64 and 65-79) specific incidence rate, and the age- and period- increasing rate of lung adenocarcinoma in differences age groups and periods. Further we used the Poisson regression to estimate the relative risk and 95% confidence interval (95% CI).
Results: In 1983-1987 and 1993-1997, the ASIR raised from 4.94 to 8.27 among males and 3.05 to 6.52 among females per 100,000 persons in Taiwan. The ASIR among males was higher than females except Iceland and the male to females ratio in most countries declined as age increased. In Taiwan, used the age in 30-44 as baseline, in 1983-1987 at 45-64 and 65-79 years old in males of the increasing rate of lung adenocarcinoma was 965.12 % and 2468.22 %, females was 622.31% and1279.34%.
Most countries the lung adenocarcinoma increasing rate of males is higher than females, except India and Spain in 1983-1987. Contrary, in the period effect, Taiwanese age-standardized lung adenocarcinoma increasing rate was 67.41% among males and females was 113.77%, most countries the increasing rate of females in different age groups is higher than the males.
Conclusion: In the absolute comparison, females have not higher risk to develop lung adenocarcinoma than males. But in relative comparison, females have a higher relative risk of lung adenocarcinoma in period effect; Males have higher relative risk of lung adenocarcinoma in age effect.
