肺癌心包积液与其影像及病理分型关系的临床分析

目的　探讨肺癌心包积液与影像学及肺癌病理组织学分类关系。方法　分析近一年来经胸部CT或心脏B超证实肺癌伴有心包积液患者的影像及病理特点。结果　在 2 0 5例肺癌患者中 ,①影像学方面 :中央型肺癌伴心包积液占 10 6 % ,周围型肺癌伴心包积液占 10 1% ,弥漫型肺癌伴心包积液占 3 5 7% ;②病理组织学方面 :肺腺癌伴心包积液占 12 12 % ,肺鳞癌伴心包积液占 3 17% ,肺小细胞癌伴心包积液占2 2 72 % ,肺腺鳞癌伴心包积液占 9 0 9% ,未分化大细胞癌伴心包积液占 10 %。经比较 ,提示肺癌影像学分型方面中央型肺癌与周围型肺癌的心包积液差异无显著意义 ,而病理组织学分型差异有显著意义 ,肺小细胞癌的心包积液较肺腺癌、肺鳞癌高。结论　肺癌发生心包积液与肺癌的病理组织学分型有密切关系 ,肺小细胞癌较肺腺癌、肺鳞癌更易发生心包积液 ;而与肺癌的影像学分型无明显关系。

An analysis on the relationship between the pericardial effusion caused by lung cancer and its imaging and pathological features

Objective To study the relationship between the pericardial effusion caused by lung cancer and its imaging and pathological features.Methods The clinical materials of 205 patients with lung cancer were retrospectively analysed.Results Among 205 cases of lung cancer,21 patients of them with pericardial effusion were proved by CT chest or cardiac ultrasonography.In the 205 cases,(1)imaging aspect:the ratio of central type lung cancer with pericardial effusion was 10.6%,peripheral type's was 10.1%,diffuse type's was 3.57%;(2)By means of histopathology,we finded that lung adenocarcinoma with pericardial effusion was in 12.12%,lung squamous cell carcinoma's was in 3.17%,small cell lung carcinoma's was in 22.72%,adenosquamous carcinoma's was in 9.09%,large cell lung cancer's in 10%.Conclusion There is closely relationship between pericardial effusion from lung cancer and pathological type of lung cancer:Small cell lung cancer is liable to metastasize to the pericardium.There is no obviously relationship between pericardial metastasis from lung cancer and imaging classification.
