摘要
目的分析体检人群低剂量CT(LDCT)早期肺癌筛查结果及危险因素分析。方法以2015年10月至2017年7月于我院接受无症状LDCT早期肺癌筛查体检者53202例为研究对象进行回顾性研究,根据美国国立综合癌症网络(NCCN)标准将研究对象分为高危组(14744例)、中危组(22341例)和低危组(16117例),分析各组体检人群肺结节检出、肺癌检出情况。结果53202例体检人群中,肺结节检出35808例(67.31%),共47329枚结节,其中阳性结节6640例(8775枚,18.54%)、单发结节27566例(36434枚,76.98%)、多发结节8242例(10895枚,23.02%)。6640例阳性结节患者中肺癌患者78例(11.75%),且I期占比最高(66.67%、52例)、II期次之(16.67%、13例)、III期再次之(12.82%、10例)、Ⅳ期最低(3.85%、3例)。高危组结节检出率(81.23%、11977例/14744例)、结节阳性率(22.63%、2710例/11977例)、结节多发率(32.55%、3898例/11977例)、肺癌检出率(0.33%、48例/14744例)最高,中危组[73.20%(16353例/123341例)、19.31%(3157例/16353例)、19.77%(3233例/16353例)、0.12%(26例/22341例)]次之,低危组[(46.39%(7478例/16117例)、10.34%(773例/7478例)、14.86%(1111例/7478例)、0.02%(4例/16117例)]最低,差异具有统计学意义(均P〈O.05)。吸烟、长期被动吸烟、慢性阻塞性肺疾病病史是筛查对象肺癌确诊的独立危险因素(OR=3.248、3.215、4.742,均P〈0.05)。结论LDCT适用于无症状体检人群的早期肺癌筛查,尤其在年龄≥55岁、吸烟≥30包/年、长期被动吸烟、有肺癌家族史、慢性阻塞性肺疾病或肺纤维化病史等肺癌高危人群中检出率较高,临床筛查中应予以重点关注。
Objective To evaluate the value of screening with low-dose computed tomography (LDCT) for patients with early lung cancer and to identify risk factors. Methods A total of 53 202 asymptomatic participants admitted to Sichuan Provincial People's Hospital from October 2015 to July 2017 took LDCT for early lung cancer screening. Based on the National Comprehensive Cancer Network (NCCN) standard, participants were divided into a high-risk group (n= 14 744), a moderate- risk group (n=22 341) and a low-risk group (n = 16117), and the detection rates of lung nodules and lung cancer were analyzed. Results Of the 53 202 participants undergoing health examinations, 35 808 (67.31%) had pulmonary nodules, including 6 640 (18.54%) with positive nodules, 27 566 (76.98%) had solitary nodules,and 8 242 (23.02%) had multiple nodules. Out of 6 640 cases with positive modules,78 (11.75%) had lung cancer,with stage I ,stage II ,stage III and stage IV making up 66.67% (n=52),16.67% (n=13),12.82% (n=10) and 3.85% (n=3) of the total. The high- risk group had significantly higher detection rates of lung nodules (81.23 %, 11 977/14 744), positive nodules (22.63% ,n=2 710) ,multiple nodules (32.55% ,3 898/11 977) ,and lung cancer (0.33% ,48/ 14 744),compared with those in the moderate-risk group and the low-risk group (all P〈0.05).Smoking,long-term passive smoking and history of chronic obstructive pulmonary disorders were independent risk factors for lung cancer among screened subjects (OR = 3. 248, 3. 215, and 4. 742, respectively,each P〈0.05). Conclusions LDCT is suitable for early lung cancer screening in asymptomatic subjects. Particular attention should be paid to those older than 55 years and those with a high smoking frequency ≥30 packs/year) ,long-term passive smoking, cancer history, family history of lung eancer,COPD or pulmonary fibrosis.
