摘要
目的分析原发性肺肉瘤样癌MSCT特征及与非小细胞癌鉴别诊断价值。方法选取本院2017年2月至2019年3月收治的15例原发性肺肉瘤样癌患者(PSC组),以及非小细胞肺癌患者81例(非小细胞肺癌组)作为研究对象,所有患者均接受MSCT检查。对两组患者所得MSCT图像进行分析,以病理结果为基准了解MSCT对原发性肺肉瘤样癌与非小细胞癌的诊断准确率,并比较两者的MSCT特征。结果MSCT对原发性肺肉瘤样癌与非小细胞癌鉴的诊断准确率分别为80.00%、97.53%,与病理检查结果一致性高(P>0.05);肺肉瘤样癌常发生于右中、上肺叶,肿瘤直径>5cm,大多数患者无“分叶”征、“毛刺”征、“空泡”征、胸膜“凹陷”征,有“棘突”征、大片弱强化区存在,强化形式为薄壁环形强化;肺小细胞肺癌大多数患者存在“分叶”征、“毛刺”征、胸膜“凹陷”征,无大片弱强化区存在(P<0.05)。结论原发性肺肉瘤样癌CT征象具有特征性,肿瘤部位、边缘情况、强化形式等CT征象对其临床诊断及与非小细胞肺癌鉴别有重要参考价值。
Objective To analyze the MSCT characteristics of primary pulmonary sarcomatoid carcinoma and the value in the differential diagnosis of non-small cell carcinoma.Methods 15 patients with primary pulmonary sarcomatoid carcinoma(PSC group)and 81 patients with non-small cell lung cancer(nonsmall cell lung cancer group)treated in our hospital from February 2017 to March 2019 were selected as the research objects.All patients underwent MSCT.The MSCT images of patients between the two groups were analyzed,and the pathological results were used as a basis to understand the accuracy of MSCT in the diagnosis of primary pulmonary sarcomatoid carcinoma and non-small cell carcinoma,and to compare the characteristics of MSCT between them.Results The accuracy of MSCT in the diagnosis of primary pulmonary sarcomatoid carcinoma and non-small cell carcinoma was 80.00%and 97.53%,respectively,which was highly consistent with the results of pathological examination(P>0.05).Pulmonary sarcomatoid carcinoma often occured in the right middle and upper lung lobes,and the diameter of the tumor was>5cm.Most patients had no lobular signs,burr signs,vacuole signs,and pleural depression signs,and had spinous sign,large weakly enhanced areas.The form of enhancement was thin-walled annular enhancement.Most patients with small cell lung cancer had lobular signs,burr signs,and pleural depression signs,and there were no large weakly enhanced areas(P<0.05).Conclusion CT signs of primary pulmonary sarcomatoid carcinoma are characteristic.CT signs such as tumor location,marginal conditions,and enhanced forms have important reference values in their clinical diagnosis and identification from non-small cell lung cancer.
