原发性肝癌是我国常见高发肿瘤,每年至少发现10万例新患者,并有11万患者死亡,死亡率在恶性肿瘤中居第2位。目前手术切除仍是原发性肝癌最有效的治疗手段。但是肝癌起病隐匿,患者常无自觉症状,因此70%的患者在被确诊时,已经发展为不能切除或切除后效果也不够满意的中晚期病人[1] Primary liver cancer is a common high-risk tumor in our country. At least 100,000 new patients are found each year, with 110,000 deaths and the second highest death rate in malignant tumors.
