Los Angeles, November 4 (Xinhua) (The reporter is tall Original) The national cancer research institute of U.S.A. announces on the 4th that studies to say, compared with the situation that the X-ray is perspected, it can be earlier and finding whether the severe smoker suffers from lung cancer that CT scans, thus reduce the patient's mortality.
Researchers study the following in 3 years about more than 53,000 severe smokers who once or at present still smoked. These smokers are collected by 33 research institutions in the whole America, 74 years old at the age of 55, each person has the cigarette ages of about 30 years, and smoke a pack of cigarettes at least every day.
Scientific research personnel divide the research object into control group and experimental group at random, the personnel of control group accept every year the X-ray is perspected, the personnel of experimental group accept CT scanning every year. By October 20 this year, there are 354 people in all to suffer from the death of lung cancer in the experimental group, and the death toll of lung cancer of the control group is 442.
Researchers point out, one of the main reasons of the difference appears in two groups of personnel's mortality, it is CT that scan can as to early finding smoker suffer from lung cancer accurately, so the patient can accept and treat and cure earlier, this pair lengthened patient's life to play an important role.
U.S.A. national director of cancer research institute the intersection of Harold and the intersection of tile and silent Sri Lankan say discovery this to public and healthy resisting lung cancer to be significant. But he points out, though CT scans and can reduce and smoke the mortality of the lung cancer patient at the same time, but can not prevent lung cancer from happening, can't change the current situation that hundreds and thousands of smokers die of lung cancer either, so the best means to prevent lung cancer is not to smoke.
