手术切除是亚临床肝癌的唯一的治疗方法。一般认为,凡甲胎蛋白对流免疫电泳法阳性,血清浓度≥200mμ/ml持续3周,或≥200mμ/ml持续8周,并能排除活动性肝炎,或妊娠,畸胎瘤等原因引起的增高外,均应考虑本病,对病人说明早期手术的重要性和必要性,争取早日剖腹探查。一、术前准备:术前明确定位是手术切除成功的关键。B型超声检查能发现直径2cm左右的肝瘤,因此,术前B型超声检查是肿瘤定位的首选方法。有条件者可经股动脉,采用Seldinger法,作选择性腹腔动脉或肝动脉造影定位。必要时行CT检查。CT能发现更小的肝癌,但费用昂贵,故不能普遍使用。
Surgical resection is the only treatment for subclinical liver cancer. It is generally believed that where alpha-fetoprotein is positive by convection immunoelectrophoresis, the serum concentration is ≥200mμ/ml for 3 weeks, or ≥200mμ/ml for 8 weeks, and active hepatitis can be excluded, or pregnancy, teratoma and other causes may increase. In addition, the disease should be considered and the importance and necessity of early surgery should be explained to the patient and an early exploratory laparotomy should be pursued. First, preoperative preparation: Preoperative clear positioning is the key to successful surgical resection. B-ultrasonography can detect liver tumors with a diameter of about 2 cm. Therefore, preoperative B-mode ultrasound examination is the preferred method for tumor localization. Candidates may use the Seldinger method to perform selective celiac artery or hepatic arterial angiography through the femoral artery. CT examination if necessary. CT can find smaller liver cancer, but it is expensive and cannot be used universally.
