CT对周围型肺腺癌与鳞癌的鉴别诊断价值

Differential diagnostic value of CT on peripheral pulmonary adenocarcinoma and squamous cell carcinoma

目的探讨CT对周围型肺腺癌与鳞癌的鉴别诊断价值。方法选取2016年12月至2018年12月在本院经病理检查确诊的周围型肺癌患者100例,根据病理类型分为腺癌组和鳞癌组,回顾性分析两组患者的CT检查结果,比较特征。结果鳞癌分叶征和边缘光滑比例均明显高于腺癌,而腺癌在CT上表现为胸膜凹陷征、毛刺、血管集束征比例明显高于鳞癌(P<0.05);肺鳞癌肺门和纵隔淋巴结肿大发生率明显高于腺癌(P<0.05);鳞癌1期和2期比例明显低于腺癌(P<0.05)。结论鳞癌在CT上主要表现为分叶征和边缘光滑,而腺癌主要表现为胸膜凹陷征、毛刺和血管集束征,鳞癌淋巴结转移发生率和临床分期较腺癌高。

Objective To explore the differential diagnostic value of CT on peripheral pulmonary adenocarcinoma and squamous cell carcinoma.Methods 100 patients with peripheral pulmonary cancer diagnosed by pathology in our hospital from December 2016 to December 2018 were selected.According to the pathological types,they were divided into adenocarcinoma group and squamous cell carcinoma group.The CT findings of the two groups were retrospectively analyzed,and their characteristics were compared.Results The proportions of lobulation sign and smooth marginal of squamous cell carcinoma were significantly higher than those of adenocarcinoma while the proportions of CT findings of pleural indentation,burr and vessel convergence sign of adenocarcinoma were significantly higher than those of squamous cell carcinoma(P<0.05).The incidence rates of hilar lymphadenopathy and mediastinal lymphadenopathy of squamous cell carcinoma were significantly higher than those of adenocarcinoma(P<0.05).The proportions of stage 1 and phase 2 of squamous cell carcinoma were significantly lower than those of adenocarcinoma(P<0.05).Conclusion Squamous cell carcinoma is mainly characterized by lobulation signs and smooth marginal on CT,and adenocarcinoma is mainly characterized by pleural indentation,burr and vessel convergence sign.The incidence rate of lymph node metastasis and clinical stage of squamous cell carcinoma are higher than those of adenocarcinoma.
