周围型肺癌CT征象与病理的对照相关性研究

A Comparative Study of CT Signs and Pathology of Peripheral Lung Cancer

目的探讨周围型肺癌CT征象与病理的对照相关性。方法选取周围型肺癌患者80例,同时选取肺部炎性假瘤患者80例,回顾性分析其临床资料,全部患者均接受CT检查与病理学检查,对两种检查方式的关联性与差异进行分析,同时比较两组CT征象。结果本组80例患者中共包括51例腺癌,16例鳞癌,9例腺鳞癌以及4例小细胞癌,不同病理类型的病灶部位具有差异;鳞癌患者常见分叶征,腺癌患者常见毛刺征,不同类型病灶CT征象具有明显差异(P<0.05);相较于炎性假瘤组,周围型肺炎组的分叶征、胸膜凹陷征以及短毛刺征发生率更高,长毛刺、尖角征以及切线征发生率更低,差异有统计学意义(P<0.05)。结论周围型肺癌CT与病理学检查结果间关联性较强,可为分型与分期判断的参考。

Objective To investigate the correlation between CT signs and pathology of peripheral lung cancer.Methods 80 patients with peripheral lung cancer and 80 patients with pulmonary inflammatory pseudotumor were selected.The clinical data were retrospectively analyzed.All patients received CT examination and pathological examination.The correlation and difference between the two examination methods were analyzed,and the CT signs of the two groups were compared.Results There were 51 cases of adenocarcinoma,16 cases of squamous cell carcinoma,9 cases of adenosquamous cell carcinoma and 4 cases of small cell carcinoma;Lobulation sign was common in patients with squamous cell carcinoma,burr sign was common in patients with adenocarcinoma,and CT signs of different types of lesions were significantly different(P<0.05);Compared with the inflammatory pseudotumor group,the incidence of lobulation sign,pleural indentation sign and short hairpin sign was higher in the peripheral pneumonia group,and the incidence of long hairpin sign,sharp angle sign and tangent sign was lower,the difference was statistically significant(P<0.05).Conclusion There is a strong correlation between CT and pathological findings of peripheral lung cancer,which can be used as a reference for classification and staging.
