【摘要】 对５２例外科治疗的小肝癌进行临床分析。切除术后５年生存率为５３．２％。资料表明，ＡＦＰ是早期肝癌定性诊断的主要手段，ａＤＢＰ是早期肝癌的敏感标记物，其阳性率达９３．８％，对ＡＦＰ阴性或低浓度阳性者同样敏感，其特异性尚待进一步观察研究。用Ｂ超在术前作体表定位标记有助于术中探寻病灶。ＣＴ是良好的病灶定位标记，通过ＣＴ测定肿瘤与肝脏隔顶的距离、与脊柱的距离以及距肝包膜的深度，三线交点作为肿瘤定位的方法可帮助术中发现难于寻找的小病灶。本文还对避免遗留癌，术后监测亚临床复发和对复发后的处理、预防等作了探讨。更多还原

【Abstract】 Fifty-two cases of small liver cancer treated by surgery were analyzed.The 5-year survival rate was 53. 2 percent. The data of AFP assay was theprinciple measure in the early diagnosis of small liver carcinoma. The aDBP was alsotaken as a sensitive tumor marker for HCC,and in the 30 cases of this series inwhom it was determined a positive rate of 93. 8% was achieved.BUS which was used to make topographic marks onthe body surface provided much help in localizing the focus during operation. CT scean was useful also in localization of the tumor focus. By measuring the distances from the tumor to the diaphragmatic dome of the liver,to the vertebra and to the liver capsule on CT scan as well the tumor could be located at the point where the three lines converge.Thereby the small unheeded cancer focus can be detected during operation with ease.更多还原
