肺腺癌患者胸部CT影像学特征及病理分析

目的分析肺腺癌患者的胸部CT影像学以及病理特征。方法回顾性分析2013年1月到2015年12月的38例经手术病理证实的肺腺癌患者的胸部CT扫描资料,分析其CT影像学特征以及病理特征。结果38例肺腺癌的直径为10-64mm,平均(30±5)mm,其中,20例直径20mm,18例直径20mm。肺腺癌肿块密度均匀13例(41%),不均匀25例(59%)。胸部CT显示低分化肺腺癌15例(39.5%),中分化肺腺癌10例(26.3%),原位腺癌7例(18.4%),微浸润腺癌6例(15.8%),检出率差异与手术病理证实结果相比较吻合好,无统计学意义(P0.05)。结论肺腺癌的CT影像学的不同特征与不同亚种的肺癌病理特征一一对应,为临床上对肺腺癌的诊断提供了有效的方法。

Analysis of CT Imaging and Pathlogical Features of Lung Adenocarcinoma

Objective To explore the imaging and pathlogical features of CT in the diagnosis of lung adenocarcinoma.Methods The data of CT in 38 patients with lung adenocarcinoma confirmed by operation and pathology from Jan,2013 to Dec, 2015 were analyzed retrospectively. The diagnostic results of CT and pathology were compared and analyzed.Results 38 cases of this group of patients with lung adenocarcinoma, by CT diagnosis, cancer diameter varied from 10 to 64 mm,with the average level of (30±5)mm.Among them,20 cases were less than 20 mm while the others were larger than 20mm.CT images of chest showed that 15 cases belonged to poorly differentiated adenocarcinoma,and 10 cases moderately differentiated adenocarcinoma, In situ adenocarcinoma 7 cases (18.4%), micro infiltrating adenocarcinoma 6 cases (15.8%). Detection rate differences compared with surgical pathology confirmed results fit well, no statistical significance (P<0.05).Conclusion The CT imaging features of lung adenocarcinoma matched pathlogy of different carcinoma subtypes,which provides a believable method in the clinical diagnosis of lung cancer.
