摘要
目的 研究癌细胞DNA含量与周围型肺癌CT征象的关系。方法 取资料齐全者 32例 ,用病理图像分析仪采用吸光度法对癌细胞核DNA含量检测 ,所得数据资料与CT征象进行相关性分析。结果 瘤体直径 >3cm者 ,DI值显著高于瘤体直径≤ 3cm(P <0 0 1) ;深分叶征、棘状突起、含气支气管征、血管集束征、胸膜凹陷征和淋巴结转移的有无 ,DI值比较均有统计学差异 (P均 <0 0 1)。结论 周围型肺癌的肿块 >3cm ,深分叶征、棘状突起、含气支气管征、血管集束征、胸膜凹陷征和淋巴结转移等CT征象均与癌细胞的DNA含量有显著相关。
Objective Purpose To study the correlation between DNA contentsand CT feature of peripheral lung carcinomas. Methods The DNA contents of 32 patients withperipheral lung carcinomas were measured by means of photodensity method with pathologicalimage analyzer. Results Tumors with diameter over 3cm had higher DI value ( P <0 01); tumor with air-bronchogram, deep lobulation, spiculate protuberance, pleura indentation or mediastinal lymph nodemetastasis had remarkable difference in DI value( P <0 01). Conclusion The peripheral lung carcinomas with diameter over 3cm, and showde deep lobulation, spiculate protuberance, air-bronchogram, pleura indentation or mediastinal lmyph node metastasis had significantly correlation with DNA contents.
