Screening results and compliance analysis of low-dose spiral CT for lung cancer in Hunan from 2017 to 2018

Objective The of this study was to analyze the preliminary results of low-dose spiral CT(LDCT)screening for lung cancer and the influencing factors of the compliance in the Cancer Screening Program in Urban China in Hunan province from 2017 to 2018,so as to provide information for the prevention and control of lung cancer.Methods In five districts of Changsha city,all permanent residents aged 40~74 years were invited to fill in the high risk assessment questionnaire.The detected high-risk lung cancer patients received LDCT clinical screening for lung cancer.The results of high-risk lung cancer assessment and LDCT screening were analyzed,and logistic regression was used to analyze the influencing factors for the compliance rate of LDCT screening.Results A total of 74,768 people participated in the evaluation of high-risk groups in two years,and 12,789 people were evaluated as high-risk groups of lung cancer,with a high-risk rate of 17.1%;among them,6,406 people LDCT screening,with a compliance rate of 50.1%.A total of 64 participants(1.0%)suspected lung cancer were found in LDCT screening,and 268 patients(4.2%)were found to be positive pulmonary nodules.The detection rates of suspected lung cancer and positive pulmonary nodules increased significantly with the increase of age.Multivariate analysis was conducted on the research subjects participating in LDCT screening,and it was found that ten variables of age,education level,occupation,occupational exposure history,vegetable intake,indoor oil fume,regular physical exercise,recent mental depression,history of chronic respiratory diseases and family history of lung cancer were significantly associated with the LDCT screening compliance(P＜0.05).Conclusion This study found the influencing factors of LDCT screening compliance,and provided a theoretical basis for the improvement of LDCT screening compliance,and improved the effectiveness of lung cancer screening and early diagnosis and treatment programs in the future.
