摘要：This study was to investigate the epidemiology of lung cancer in Jianghan Plain, providing scientific basis for prevention and treatment of lung cancer. Pathology and clinical data of 1290 patients diagnosed lung cancer from the largest hospital in Jianghan Plain were collected and analyzed. Results found that the lung cancer incidence increased gradually from the age of 40 and at the peak during 61 to 70 years old; the male to female ratio was 2.45:1; Smoking patients were 841 cases, accounting for 65.2% of all cases. Smoke index > 400 was 771 cases accounting for 91.7 percent of smokers and smoking index < 400 was 70 cases accounting for 8.3% of smoking patients. 93.6% of the patients were to start smoking at a young age. The rate of patient pathological cytology diagnosed by fiberoptic bronchoscopy was 31.8%, which showed that it was an important diagnostic method for lung cancer. The main reason for smoking is to break up the monotony and although many patients know nicotine, carbon monoxide is the main smoking harmful substances and smoking may cause lung cancer; not many people can take the initiative to quit smoking. It also showed that squamous cell carcinoma was the main type in smoking patients, while adeno-carcinoma in non-smoking patients. The comprehensive epidemiological analysis suggested that smoking is an important factor in causing lung cancer, smoking cessation education and regular medical examinations to strengthen the prevention of lung cancer have a positive meaning to their family members.
