【摘要】 目的研究肺腺癌强化程度、肿瘤大小和肿瘤转移关系。方法回顾性分析63例肺腺癌经手术病理或穿刺活组织检查证实的病例,患者进行CT常规平扫和增强扫描,并测量其前后CT值及统计肿瘤大小。结果肺腺癌强化程度及肿瘤大小和肿瘤转移有关。重度强化肺腺癌的转移率明显高于轻中度强化肺腺癌者,差异有统计学意义(P<0.01);>3cm肺腺癌的转移率明显高于≤3cm肺腺癌者,差异有统计学意义(P<0.01)。结论通过对肺腺癌强化程度、肿瘤大小研究,能预测其发生转移可能性。更多还原

【Abstract】 Objective To study the relation between the degree of enhancement,tumor size and tumor metastasis in adenocarcinoma of lung.Methods Sixty three cases of adenocarcinoma of lung confirmed by biopsy or pathology were analyed retrospectively,Both plane scan and contrast-enhanced CT were performed in all the patients,And CT value of each adenocarcinoma of lung were measured,testing statistically tumor size.Results There was the relationship between the degree of enhancement,tumor size and tumor metastasis in adenocarcinoma of lung.The metastasis of severe enhancement was more higher than that of mild to moderate enhancement in adenocarcinoma of lung(all P<0.01);the metastasis of >3 cm was more higher than that of ≤3 cm in adenocarcinoma of lung(all P<0.01).Conclusion It is helpful for predicting the latent possibility of adenocarcinoma of lung metastasis by study the relation between the degree of enhancement,tumor size and tumor metastasis in adenocarcinoma of lung.更多还原
