中央型小细胞肺癌与鳞癌的多层螺旋CT比较研究

A Comparative Study of Multislice Spiral CT in Central Type Non-small Cell Lung Cancer and Squamous Cell Carcinoma of the Delta

目的:探讨中央型小细胞肺癌与鳞癌的多层螺旋CT比较。方法:选取某院经病理证实的中央型小细胞肺癌患者43例作为对照组,同时收集同期经病理证实的中央型肺鳞癌患者44例作为观察组,观察两组患者的CT表现。结果:两组患者CT征象中胸膜腔积液、远处转移、心脏大血管受侵、纵隔肺门淋巴结肿大、淋巴结融合、支气管狭窄无阻塞、肺叶实变、肿瘤不均匀强化、肿瘤坏死、支气管闭塞出现率存在显著性差异(P<0.05);经Logistic回归分析,淋巴结融合、远处转移、支气管狭窄无阻塞与中央型小细胞肺癌呈正相关,肿瘤不均匀强化与中央型鳞癌呈现正相关。结论:中央型小细胞肺癌与鳞癌的多层螺旋CT比较存在一定差异,对两者鉴别有应用价值。

Objective. To investigate the comparison of multi-slice spiral CT in the diagnosis of small cell lung cancer and squamous cell carcinoma. Methods： 43 cases with central type non-small cell lung cancer confirmed by pathology were taken as control group, while at the same period 44 patients with central type lung squamous cell carcinoma were confirmed by pathology taken as the observation group. Then CT performance of the two groups. Results： CT signs of pleural effusion, distant metastasis, cardiac vascular invasion, mediastinal and hilar lymph node, lymph nodes, bronchial stenosis without obstruction, lobe consolidation, tumor heterogeneous enhancement, tumor necrosis, bronchial occlusion rate of the two groups had significant difference （P 〈0.05） ; by logistic regression analysis, lymph node metastasis, fusion, bronchial stenosis and obstruction was positively related to central type non-small cell lung cancer and tumor inhomogeneous was positively related to central squamous cell carcinoma. Conclusion： There are some differences in the comparison of multi slice spiral CT between central small cell lung cancer and squamous cell carcinoma, which has application value in the identification of the two tyoes of cancer.
