Community-based practice of early lung cancer screening with low-dose spiral computed tomography in Jiaxing city from Zhejiang Province

e13557 Background: As one of the most frequent malignant tumors in China, the morbidity and mortality of lung cancer remain high. Early diagnosis and normative treatment is the key to improve the prognosis of lung cancer. The aim of this study is to explore the practice of early lung cancer screening with low-dose spiral computed tomography (CT) based on the current situation in community health service, with integration of superior resources of medical institutions at all levels in Jiaxing City from Zhejiang Province. Methods: From Jan. 2017 to Dec. 2019, we screened 13491 (male 8783, female 4708) individuals high-risk population in selected communities of Nanhu District, Pinghu County and Haiyan County, Zhejiang Province, for early diagnosis of lung cancer with low-dose spiral CT combined with multidisciplinary comprehensive treatment models including minimally invasive surgery, exploring the medical service network covering prevention, diagnosis, treatment, rehabilitation and follow-up. Results: Screening resulted in a diagnosis of cancer in 27 participants. Of these participants, 24 cases of primary lung cancer, 1 case of lung metastasis, 1 case of breast cancer, 1 case of thyroid cancer. The morbidity of primary lung cancer is 224.53×10-5. There were 20 cases of Stage 0-Ⅰlung cancer accounting for 83.33% of all diagnosed primary lung cancer. Conclusions: Based on community health service, screening with LDCT could improve the early diagnosis rate of lung cancer in both smokers and nonsmokers with feasibility and validity, which could be applicable in qualified eligible medical centers and communities in China. It is not reasonable to exclude nonsmokers from screening with LDCT.
