乌鲁木齐市社区肺癌高危人群低剂量螺旋CT筛查结果分析

An Analysis of Lung Cancer Screening with Low-Dose Computed Tomography for High-Risk Population in Urumqi Community

[目的]对乌鲁木齐市城市社区40-69岁人群开展肺癌筛查,评价筛查效果。[方法]对问卷评估的11 512名肺癌高危人群低剂量螺旋CT检查。[结果]共完成肺癌CT筛查3436人,依从性为20.4%。共发现1294人有肺内结节（37.6%）,367人有阳性结节（10.7%）,可疑肺癌16例（0.46%）。男性阳性结节的检出率高于女性。60-69岁年龄组在阳性结节、小结节、可疑肺癌的检出率都高于其他年龄组。[结论]低剂量螺旋CT适合肺癌的高危人群筛查,有助于早期发现肺内的阳性结节和相关疾病,60岁以上人群肺癌的筛查应该引起高度重视。

[Purpose] To carry out lung cancer screening for the population aged 40-69 in Urumqi urban community,and to evaluate its effectiveness. [Methods] A total of 11 512 high-risk lung cancer patients were evaluated by questionnaire surveys,and further underwent the low-dose spiral CT examination. [Results] The 3436 people were performed CT screening for lung cancer with compliance rate of 20.4%,and 1294 people（37.6%） were with pulmonary nodules,367（10.7%）people with positive nodules and 16 patients（0.46%） with suspected lung cancer. The detection rate of positive nodules in male was higher than that in female. The detection rate of positive nodules in the age group 60 -69 was higher than that in other age groups. [Conclusion] Low-dose spiral CT is suitable for screening for high-risk lung cancer,it can help early detection of positive nodules and lung-related diseases. Lung cancer screening for people over 60 years-old should be paid more attention to.
