IntroductionLung cancer is a fatal problem of common sanitation in the world. According to the information publicized by WHO in 2003,the incidence of lung cancer and its mortality have increased about 22%. Lung cancer becomes the dominating cancer all around the world not only because of its amount of patients(1.2 million per year) but of its death toll(1. 1 million per year).The incidence of lung cancer in China increases fast——in 2000,the figure of the new patients was 1.8-2.0 million, and the decedents 1.4-1.5 million, and the incidence was 367 per million. The total amount of patients ranks first in the world, making China the biggest lung cancer country.This study describes the tendency of lung cancer in Shenyang from 1998 to 2006 by stating the methodology of epidemiology, analyzes the mortality variation trend and constituents of the decedents of lung cancer and their reasons, depicts the death situation of lung cancer in Shenyang from 1998 to 2006 with illustrations, and seeks the main hazardous factors of various crowds vulnerable to lung cancer to provide a potent basis for effective prevention of lung cancer.Objective1 .Listing the ages and genders of the decedents of lung cancer in Shenyang, and the districts they are from, and depicting the mortality variation trend of lung cancer in Shenyang from 1998 to 2006.2. Analyzing the mortality variation trend and constituents of the decedents of lung cancer and their reasons to provide a scientific basis for the prevention strategies of lung cancer in Shenyang.MethodsThe information of data comes from the lung cancer cases of the decedents diagnosed by clinic, chest X-ray, CT and pathology examination. The cases were reported to Shenyang CDC from 1998 to 2006 by various hospitals in Shenyang. Establish a database with computer after checking the reported information and affirming its facticity, with the decedents as researching objects whose dead times, ages, genders and districts these are researching factors. Input data with Excel 5.0 and analyze with SPSS 11.5 to describe the death situation of lung cancer.Results1 .the overall death situation of lung cancer in ShenyangBetween 1998 and 2006, 19,077 people died of lung cancer in Shenyang, with the CDR 629.4 per million; the amount of males is 11,528, with the Crude death rate 759.0 per million; and that of females 7,549, with the Crude death rate 498.9 per million. The mortality of lung cancer accounts for 36.72% of that of malignancy, making lung cancer chief reason of death of malignancy.2.tendency distributing of lung cancer mortality in ShenyangThe Crude death rate of lung cancer in Shenyang increases year by year, but the SMR has a tendency of "first increase and then decrease", with 2002 as the boundary.3.gender distributing of death of lung cancer in ShenyangIt is not difficult to find out that the Crude death rate of lung cancer of males increased greatly and they are the main body of the decedents of lung cancer in Shenyang; But the female patients of lung cancer should also not be ignored, since their Crude death rate of lung cancer increased slowly. Compared with that of females, the mortality of lung cancer of males in Shenyang increased obviously, and the lung cancer mortalities of males of various ages are higher than those of the female counterparts4.area distributing of death of lung cancer in ShenyangThe Crude death rate of lung cancer in Tiexi District is the highest, and also the SMR one in Dadong District. Both Crude death rate and SMR of lung cancer in Huanggu District is the lowest.5.age distributing of death of lung cancer in ShenyangNew patients of lung cancer are becoming younger in Shenyang. Since 2002, cases emerge in the group of people younger than 20; mortality in people of the 50s increases Obviously; the peak of death appears in those of the 80s. And the average age of decedents of lung cancer is about 67.Conclusions1.The mortality of lung cancer in the city zone of Shenyang is higher than the average one of the country, and the mortality of lung cancer of both males and females rank front in the country.2. Compared with that of females, the mortality of lung cancer of males in Shenyang increased obviously, and the lung cancer mortalities of males of various ages are higher than those of the female counterparts.3.SMR of lung cancer increases first and then declines due to the aging of population in Shenyang.4.New patients of lung cancer are becoming younger and the decedents older in Shenyang. The average age of decedents of lung cancer is about 67.5. The differences of the constituents of citizens in various areas of Shenyang and the changes of hazardous factors of lung cancer induced the tendency variations of death of lung cancer.
