吸烟、酗酒与较早患胰腺癌有关

Those who smoke and drink heavily may develop pancreatic cancer at an earlier age than those who don't, according to a study published Monday in the American Journal of Gastroenterology.

研究人员在新一期《美国肠胃病学杂志》上发表的报告中称，这项新的研究并不意味着大量吸烟、酗酒能直接导致较早的患上胰腺癌，但是也确实存在一定的影响。

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 defined as those who smoked more than a pack per day, and heavy drinking was measured at about three average drinks per day.

研究人员对Pancreatic Cancer Collaborative Registry国际数据库中811名胰腺癌患者的信息进行研究其中包括一般的胰腺癌患者和潜在高危的胰腺癌患者。在这项研究中，大量吸烟人群是指那些每天至少抽一包烟的人，酗酒人群是指那些每天饮酒量达到一般社交饮酒量的3倍。

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 effects 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.

来自密歇根卫生系统的研究人员发现，其中大量吸烟者被诊断患胰腺癌时的平均年龄约为62岁，酗酒者被发现患胰腺癌时的平均年龄约为61岁，而不吸烟、酗酒的胰腺癌患者患该病的平均年龄在72岁左右。不过大量吸烟和酗酒的有害影响可以逆转——如果戒烟、戒酒10年以上，较早患胰腺癌的风险不会增加。

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.

研究人员警告说,这项研究只表明这些习惯会导致较早患上胰腺癌,而不能证明习惯是导致癌症的原因。
