隐匿型肺癌X线胸片漏诊分析及CT扫描的临床意义

Missed diagnosis analysis of occult lung cancer by X-ray and the clinical significance of CT scans

目的：分析 X 线胸片漏诊隐匿性肺癌的原因，并评价 CT 扫描对隐匿性肺癌的诊断价值。方法选择 X 线漏诊的隐匿性肺癌43例患者为研究对象。通过比较 X 线和 CT 检查结果，分析 X 线漏诊原因。结果43例患者正位 X 线胸片结果显示无异常，行侧位 X 线胸片检查后，30例患者依然未见异常。CT 扫描证实43例患者全为隐匿性肺癌。CT 扫描对支气管腔内、肺门区肿块及纵隔淋巴结肿大的显示情况优于 X 线胸片检查，差异有统计学意义（P ﹤0.05）。结论 X 线诊断隐匿性肺癌的漏诊率高。对于疑似隐匿性肺癌的患者，有必要行 CT 扫描，及早发现隐匿性肺癌，进一步确定病情，并采取针对性治疗。

Objective To analyze the missed diagnosis causes of occult lung cancer by X-ray, and evaluate the diagnosis value of CT scans on occult lung cancer. Methods Forty-three patients with occult lung cancer missed diagnosed by X-ray were chose as study objects. By comparing the results of X-ray and CT examination,the missed diagnosis causes of occult lung cancer by X-ray were analyzed. Re-sults The anteroposterior chest X-ray results were not abnormal in all of the 43 patients,and the lateral chest X-ray results were not abnormal in 30 patients. All of the 43 patients were confirmed with occult lung cancer by CT scans. CT scan was superior to the chest X-ray in display the bronchial lumen,lung hilar tumor and mediastinal lymph nodes enlargement,there were significant differences（ P ﹤ 0. 05）. Conclusions The missed diagnosis rate of occult lung cancer by X-ray is high. For patients with suspec-ted occult lung cancer,CT scan is necessary to early detection of occult lung cancer,further define the disease,and take targeted treatment.
