肝细胞癌影像学表现与转移的关系

Relationship of imaging to metastasis in hepatocellular carcinoma

目的 :从影像学表现预测肝细胞癌 (HCC)发生转移潜在可能性。方法 :1 34例经手术病理证实的 HCC患者 ,术前全部进行 CT常规扫描和动态增强扫描。对肿瘤及瘤周组织进行评价、分级 ;CT表现与病理结果以及患者随访情况进行比较分析。结果 :(1 )肿瘤直径大于 3 cm者发生转移的机会明显高于 3 cm以下者 ;(2 )重度增强发生转移的可能性明显高于轻中度增强 ;(3)出现门静脉癌栓、动静脉瘘和病灶周围肿瘤血管者发生转移的机会明显高于无上述表现者。结论 :本文结果提示 ,可从 HCC肿瘤大小、增强程度和一些增强

Objective: To study the question whether CT imaging predicts the potential metastasis in hepatocellular carcinoma (HCC) Methods: A total of 134 patients with HCC received preoperatively CT plain and dynamic contrast scans The neoplasms and surrounding tissue were estimated and graded by pathologist CT imaging,histopathological result and follow up information were analyzed Results:The incidences of metastases in patients with tumor diameter 3 cm or more and heavy enhancement were much higher than those with diameter less 3cm and mild or moderate enhancement There was a high metastatic rate in subjects with cancer emboli in the portal vein,arteriovenous fistulae and peritumor vascularization Conclusion: Tumor size,enhancing degree and other contrast appearances could be used to judge the metastatic potential of HCC
