肝细胞癌的预后不良,据报告有的5年生存率仅4—8%。这种肿瘤的手术切除是已知的唯一有效治疗方法。但手术是复杂的并且要求尽可能确定肿瘤的部位和范围。放射核素扫描、电子计算机扫描以及超声检查等这样一些诊断方法能决定肿瘤的位置并可显示其是否为孤立性或多中心性。针吸活检可明确其组织学性质。然而唯有血管造影才能确定具体的肝叶和段,因而才能提供外科医生进行肝切除所需的资料。
The prognosis of hepatocellular carcinoma is poor, and it is reported that the 5-year survival rate is only 4-8%. Surgical removal of this tumor is the only known effective treatment. However, surgery is complicated and requires that the location and extent of the tumor be determined as much as possible. Diagnostic radionuclide scans, computer scans, and ultrasonography can determine the location of the tumor and show whether it is isolated or polycentric. Needle biopsy can clarify its histological properties. However, only angiography can determine the specific lobe and segment, thus providing the surgeon with the information needed for hepatectomy.
