【摘要】 目的探讨沂蒙老区早期肺癌的筛查模式。方法在沂蒙老区对36 777例人群采用低剂量螺旋CT进行肺癌筛查,依据其暴露的危险因素分为高危组和自然组,进行相关分析。结果高危组:肺结节检出率为2.16%,早期肺癌检出率为1.25%;自然组:肺结节检出率为1.49%,早期肺癌检出率为0.60%。两组肺结节及早期肺癌检出率比较均有差异(χ~2=4.09,8.60;P<0.05)。高危组中有肺部疾病史者肺癌的检出率为2.28%,高于无肺部疾病史的0.66%(χ~2=5.82,P=0.016)。结论在沂蒙老区应采用低剂量螺旋CT对有肺部疾病史者进行重点筛查。更多还原

【Abstract】 Objective To explore the screening model of early lung cancer in the old area of Yimeng. Methods In the old area of Yimeng, 36,777 patients were screened for lung cancer with low-dose spiral CT. According to their exposure risk factors, they were divided into a high-risk group and a natural group, and related analysis was carried out. Results For the high-risk group, the detection rate of lung nodules was 2.16%, and the detection rate of early lung cancer was 1.25%. For the natural group: the detection rate of lung nodules was 1.49%, and the detection rate of early lung cancer was 0.60%. There were differences in the detection rates of lung nodules and early lung cancer between the two groups(χ~2=4.09,8.60;P<0.05). The detection rate of lung cancer in the high-risk group with a history of lung disease was 2.28%, which was higher than the 0.66% without a history of lung disease(χ~2=5.82,P=0.016). Conclusion In the old area of Yimeng, low-dose spiral CT should be used for key screening of patients with a history of lung diseases.更多还原
