Result analysis of chest screening with low-dose spiral CT among 5877 examinees in enterprise-type community

目的探讨胸部低剂量螺旋CT检查在健康体检中的合理应用。方法回顾性分析2015年1—12月上海某企业职工5 877名体检资料中胸部低剂量螺旋CT检查结果,按年龄分为青年组(≤44岁)3 865名;中年组(>44~<60岁)1 741名;老年组(≥60岁)271名,计算阳性率并进行统计学分析。结果 5 877名体检者胸部低剂量螺旋CT检查总阳性率为60.22%(3 539/5 877),肺结节检出率为8.07%(474/5 877),与年龄关系密切,筛查中发现9例早期肺癌。结论胸部低剂量螺旋CT检查有助于提高早期肺癌及其他相关疾病的检出率,值得在健康体检中进一步推广应用。

Objective To investigate the rational application of chest screening with low-dose spiral CT in physical ex-amination. Methods Retrospective analysis was conducted on chest screening results with low-dose spiral CT of 5 877 employeesin an enterprise of Shanghai from January to December 2015. According to the ages,the examinees were divided into youthgroup(≤44 years,n=3 865),middle-age group(>44-<60 years,n=1 741)and elderly group(≥60 years,n=271). The positiverate was calculated and analyzed statistically. Results Among the 5 877 examinees,the total positive rate of chest screeningwith low-dose spiral CT was 60.22%(3 539/5 877),and the detection rate of pulmonary nodule was 8.07%(474/5 877),whichwas closely related with age. 9 patients with early stage of lung cancer were diagnosed in chest screening of low-dose spiral CT.Conclusion Chest screening with low-dose spiral CT,which is worthy of further promotion and application in physical exami-nation,is helpful to improve the detection rate of early stage of lung cancer and other related disease.
