截止到1985年,各种研究从不同角度(生态学和流行病学)证明了吸烟与胰腺癌之间存在着联系。1990年3月有关这一题目的Search计划的协作者们召开了讨论会并对收集到的资料进行了详细讨论和分析。资料表明,吸烟者发生胰腺癌的危险性随吸烟量增加而增大,至少在戒烟后二十年这种危险性才可能降至未吸烟者的水平。同时,有的资料也证明吸烟是胰腺癌病因中的一个重要因素。由此专家们预期:通过禁止吸烟可使胰腺癌的新病例由1980年统计的
As of 1985, various studies have demonstrated a connection between smoking and pancreatic cancer from different perspectives (ecology and epidemiology). Co-workers of the Search Project on this topic in March 1990 held a seminar and discussed and analyzed the collected information in detail. Data show that the risk of pancreatic cancer in smokers increases with the increase in smoking, at least in the twenty years after the cessation of this risk may be reduced to the level of non-smokers. At the same time, some data also prove that smoking is an important factor in the etiology of pancreatic cancer. As a result, experts expect that new cases of pancreatic cancer can be counted by 1980
