肺癌患者肺内小结节良恶性的CT检测意义分析

Analysis of the Significance of CT in Detecting the Pulmonary Benign and Malignant Nodules in Lung Cancer Patients

目的研究CT用于检测并诊断肺癌患者肺内良恶性小结节的临床价值。方法整群选取该院肿瘤科2013年10月—2015年6月期间内接收治疗的75例肺癌患者,单个患者肺内结节数量不超过2个。对全部患者的临床信息、CT检测图像进行回顾性分析,根据患者CT图像分析患者的病理类型、临床分期、结节良恶性质、位置、边缘等,以此判断与结节良恶性的关系。结果 75例肺癌患者中共检测到124个结节,其中50个结节(40.32%)诊断为良性,其他74个结节(59.68%)诊断为恶性。位于同一肺叶内判断为恶性的几率较大,且多为转移性恶性结节;另外,边缘表现为整齐的多判断为转移恶性结节。结论 64排多层螺旋CT图像通过分析结节分布位置、形状、边缘,对判断肺癌患者肺内结节良恶性具有重要诊断意义,值得临床诊断应用。

Objective To study the significance of CT in detecting the pulmonary benign and malignant nodules in lung cancer patients. Methods 75 lung cancer patients receiving treatment in the department of oncology in this hospital from October 2013 to June 2015 were included. The number of pulmonary nodules in every of them was not more than 2. The clinical data and CT test image was retrospectively analyzed, and their pathological type, clinical staging, the benignity and malignancy, location, edge of nodules were analyzed according to CT image to determine their relationship with benignity and malignancy of nodules. Results A total number of 124 nodules were detected in the 75 patients, and the result of diag-nosis showed that 50 （40.32%） of them were benign and 74 （59.68%） were malignant. There was more malignant nodule than benign one among nodules which were found in the same pulmonary lobe, in addition, most of the malignant nodules were metastatic. What＇s more, there was more chance for the nodule with clean edges to be malignant one. Conclusion 64 row multi-slice CT images, by analyzing the distribution location, shape, margin of nodules, can produce great significance in determining the benignity and malignancy of pulmonary nodules in patients with lung cancer. Therefore this method is worthy of application in clinical diagnosis.
