——Study Shows More Men Die Than Women Among Nonsmokers With Lung Cancer
Sept. 9, 2008 -- Researchers looking into lung cancers in nonsmokers have found that men seem to die from the disease more than women.
The reasons for this are not clear from the study results.
Researchers led by the American Cancer Society's Michael Thun, MD, looked at data to try to better understand how lung cancer affects men and women in different cultures and from different time periods.
They pooled information on lung cancer rates and deaths from 13 large groups representing about 2 million people around the world.
Researchers also abstracted data for women from 22 cancer registries and 10 countries in places where few women smoked.
All the participants were self-described nonsmokers.
Here are the main findings:
Men died more from lung cancer than did women in all age and racial groups studied.
Women and men 40 years old and older had similar rates of lung cancer, when the figures were standardized.
African-Americans -- and Asians living in Korea and Japan -- had higher death rates from lung cancer than did people of European extraction.
There were no time trends seen when researchers compared lung cancer rates and death rates among U.S. women ages 40 to 69 during the 1930s to nonsmoking women of today's population.
Women in East Asia had higher and more variable lung cancer rates than did women in other areas of the world where women don't smoke very much.
According to the American Cancer Society, in the U.S. 10% to 15% of all lung cancer deaths are caused by something other than smoking cigarettes. The organization also finds that nearly 1.5 million people die from lung cancer every year around the world due to tobacco smoking.
In background information published with the study results, researchers write that tumors in the lungs of people who are not smokers have "different molecular profiles and respond better to targeted therapies" than do tumors in smokers' lungs.
Researchers call for more study, noting that these findings contradict with earlier research suggesting that the risk of lung cancer in nonsmoking women and men has increased and that nonsmoking women get lung cancer more than men do.
The findings appear in September's issue of PLoS Medicine.

2008年9月9日---研究者在对不吸烟的肺癌患者进行的调研中发现，男性死于该疾病的人数似乎比女性多。
The reasons for this are not clear from the study results.
其原因在该研究的结论中不明确。
Researchers led by the American Cancer Society's Michael Thun, MD, looked at data to try to better understand how lung cancer affects men and women in different cultures and from different time periods.
由美国癌症学会的医学博士迈克·图恩领衔的科研人员对相关数据进行研究，期望从中能更好地了解肺癌是如何影响来自不同文化背景和不同时区的男性和女性的。
They pooled information on lung cancer rates and deaths from 13 large groups representing about 2 million people around the world.
他们将肺癌患病比例和死亡率的信息合并为13大组以代表全世界约两百万的人群。
Researchers also abstracted data for women from 22 cancer registries and 10 countries in places where few women smoked.
研究者被来自22个癌症登记处和10个女性烟民极少的国家的女性患者资料所吸引。
All the participants were self-described nonsmokers.
所有参与调查的人都自称不吸烟。
Here are the main findings:
Men died more from lung cancer than did women in all age and racial groups studied.
Women and men 40 years old and older had similar rates of lung cancer, when the figures were standardized.
以下是主要研究结果：
在调研的所有年龄段和不同种族中死于肺癌男性比女性多。
在人数一定的条件下，40岁及40岁以上的女性和男性的肺癌患病比例相似。
African-Americans -- and Asians living in Korea and Japan -- had higher death rates from lung cancer than did people of European extraction.
非洲裔美国人和生活在韩国、日本的亚洲人的肺癌死亡率比欧洲血统的肺癌患者死亡率高。
