An Analysis Of Epidemic Trends Of Lung Cancer In Yan Bian Area

Objectives:This paper focuses on the study of lung cancer incidence concerning young male and female patients in Yan Bian area and analyzes its trend in order to offer basic reference to prevent and cure young patients with lung cancer.Methods:The medical records of young patients with lung cancer are selected by electronic medical records system from January 1,1995 to December 31,2014, which are stored in medical records archive of Yanbian university hospital. Based on patients’gender, age, regional distribution and different pathologic types in every 5 years, crude rate of incidence, sectional shrinkage, cumulative rate and resident environment are analyzed contrastively.Results:The proportion and adjusted incidence of young male patients with lung cancer are reduced slightly and the crude rate of incidence is on rise year by year, (from 8.37/105 between 1991 and 1995 to 12.8/105 between 2010 and 2014); The proportion and crude rate of incidence of young female patients with lung cancer are increased. (from 8.37/105 to 11.0/105, but its adjusted incidence reduces from 10.38/105 to 6.0/105.); The sectional shrinkage of male between 35-64 years old is gradually increased from 10.38/105 to 15.50/105, while the sectional shrinkage of female between 35-64 years old is gradually increased from 10.38/105 to 13.7/105, the cumulative rate between 0-64 years old rises step by step from 51.9/105 to 68.3/105. The proportion of young male and female patients with squamous carcinoma and small cell carcinoma declines, whereas the incidence of young male and female patients with adenocarcinoma is on the rise. As for young male and female patients with lung cancer, the smokers occupy more proportion than non-smokers and rural residents occupy more proportion than urban residents. There is no significant difference between the Korean nationality and Han nationality.Conclusion:1. The proportion of young female patients with squamous carcinoma and small cell carcinoma in Yanbian area declines year by year, whereas the proportion of young female patients with adenocarcinoma is on the rise. There is no significant change for young male patients. The development of its pathologic type is similar to epidemiological characteristic of most developed countries.2. The crude rate of incidence of young male and female patients with lung cancer is on the rise. The sectional shrinkage between 35-64 years old and the cumulative rate between 0-64 years old are increased obviously. However, the adjusted incidence reduces year by year. People at 40s have the highest frequency of getting sick. The morbidity rate of young female patients increases year by year and is obviously higher than young male. The result is consistent with the fact that there is a rise in lung cancer based on the national monitor of malignant tumor in 2009.3.As for young male and female patients with lung cancer, the smokers occupy more proportion than non-smokers and rural residents occupy more proportion than urban residents. There is a significant difference among young female patients. The incident trend is similar to other areas in China. There is no significant difference of disease incidence between the Korean nationality and Han nationality.
