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。
