【雙語閱讀】吸煙、酗酒與較早患胰腺癌有關(guān).

　　Those who smoke and drink heavily may develop pancreatic cancer at an earlier age than those who don&apost, according to a study published Monday in the American Journal of Gastroenterology.

　　The study involved 811 pancreatic cancer patients from the international database Pancreatic Cancer Collaborative Registry, which gathers information on patients with pancreatic cancer and at high-risk for developing pancreatic cancer. In the study, heavy smokers were dined as those who smoked more than a pack per day, and heavy drinking was measured at about three average drinks per day.

　　The researchers from University of Michigan Health System found the heavy smokers with pancreatic cancer were diagnosed around age 62 and heavy drinkers at age 61 -- almost a decade earlier than the average age of 72. However, the harmful fects of heavy drinking and smoking could be reversed -- after 10 years, former smokers and drinkers who quit their habits faced no extra risk of earlier diagnosis, the study said.

　　The researchers cautioned that the study only indicates these habits can lead to developing pancreatic cancer earlier in life, instead of proving the habits caused cancer.

　　研究人員在新一期《美國腸胃病學雜志》上發(fā)表的報告中稱，這項新的研究并不意味著大量吸煙、酗酒能直接導致較早的患上胰腺癌，但是也確實存在一定的影響。

　　研究人員對Pancreatic Cancer Collaborative Registry國際數(shù)據(jù)庫中811名胰腺癌患者的信息進行研究，其中包括一般的胰腺癌患者和潛在高危的胰腺癌患者。在這項研究中，大量吸煙人群是指那些每天至少抽一包煙的人，酗酒人群是指那些每天飲酒量達到一般社交飲酒量的3倍。

　　來自密歇根衛(wèi)生系統(tǒng)的研究人員發(fā)現(xiàn)，其中大量吸煙者被診斷患胰腺癌時的平均年齡約為62歲，酗酒者被發(fā)現(xiàn)患胰腺癌時的平均年齡約為61歲，而不吸煙、酗酒的胰腺癌患者患該病的平均年齡在72歲左右。不過大量吸煙和酗酒的有害影響可以逆轉(zhuǎn)——如果戒煙、戒酒10年以上，較早患胰腺癌的風險不會增加。

　　研究人員警告說,這項研究只表明這些習慣會導致較早患上胰腺癌,而不能證明習慣是導致癌癥的原因。
