多层螺旋CT用于小细胞肺癌与肺鳞癌的鉴别诊断价值分析

目的 分析多层螺旋CT用于小细胞肺癌与肺鳞癌的鉴别诊断价值。方法 选取2015年1月~2017年12月本院接收的肺癌患者106例，由病理类型分组，小细胞肺癌53例作为A组，另53例为肺鳞癌作为B组，两组患者均需进行多层螺旋CT鉴别诊断，回顾分析两组影像学特征以及A组相关危险因素。结果 A组和B组在密度、性状、强化形式、支气管形态、阻塞性改变、淋巴结融合、淋巴结肿大、大血管侵袭等影像特征对比上，差异具有统计学意义（P＜0.05），但在远处转移、胸膜转移和心包积液等特征比较上，差异无统计学意义（P＞0.05）。经多因素分析得知，小细胞肺癌的危险因素主要为支气管狭窄通畅、肿瘤均匀强化和淋巴结融合。结论 多层螺旋CT用于小细胞肺癌与肺鳞癌具有较高的鉴别诊断价值，能清晰显示出小细胞肺癌与肺鳞癌的影像特征差异，为临床鉴别诊断提供科学的参考依据。

Value of Multi-slice Spiral CT in Differential Diagnosis of Small Cell Lung Cancer and Lung Squamous Cell Carcinoma

Abstract:Objective To analyze the value of multi-slice Spiral CT in differential diagnosis of small cell lung cancer and lung squamous cell carcinoma.Methods A total of 106 patients with lung cancer admitted to our hospital in January 2015 to December 2017 were divided according to their pathological types,53 patients with small cell lung cancer were selected as group A and 53 patients with squamous cell carcinoma were selected as group B.Multi-slice Spiral CT was used to differentiate the two groups.The imaging features and risk factors of group A were analyzed retrospectively.Results There were significant differences between group A and group B in density,character,enhancement form,bronchial morphology,obstructive changes,lymph node fusion,lymph node enlargement,macrovascular invasion and other imaging features(P<0.05).However,there was no significant difference in distant metastasis,pleural metastasis and pericardial effusion(P>0.05).Multivariate analysis showed that the main risk factors of small cell lung cancer were bronchostenosis,homogeneous enhancement and lymph node fusion.Conclusion Multi-slice spiral CT has a high value in differential diagnosis between small cell lung cancer and lung squamous cell carcinoma.It can clearly show the difference of imaging features between small cell lung cancer and lung squamous cell carcinoma and provide a scientific reference for clinical differential diagnosis.
