目的　评价介入治疗作为小肝癌综合治疗手段的临床疗效。方法　回顾性分析经病理学或细胞学证实、直径≤ 3cm、在治疗过程中 18例曾选用介入治疗的原发性肝癌的临床疗效。结果　全组 7例手术患者术后复发。 2例发生远处转移。Kaplan meier法计算 1、2年累积生存率分别为 10 0 %、83 3 %。结论　手术是小肝癌的首选治疗方法 ,切除后肿瘤复发是影响小肝癌远期疗效的重要因素 ,预防术后复发是延长生存期最理想的措施 ,亚临床复发的早期发现是提高复发后生存率的关键。介入治疗是小肝癌综合治疗方法中非手术治疗的重要手段 Objective To evaluate the clinical efficacy of interventional therapy as a comprehensive treatment for small hepatocellular carcinoma. Methods A retrospective analysis of the clinical efficacy of primary liver cancer with pathological or cytological confirmation, diameter ≤ 3cm, and 18 cases of interventional treatment was used during the treatment. Results Seven cases of surgical patients in the whole group relapsed. Two cases had distant metastases. The Kaplan meier method calculates the 1-year and 2-year cumulative survival rates as 100% and 83%, respectively. Conclusions Surgery is the first choice for treatment of small hepatocellular carcinoma. Resection of the tumor after resection is an important factor affecting the long-term efficacy of small hepatocellular carcinoma. Preventing postoperative recurrence is the best measure to prolong survival. The early detection of subclinical recurrence is to improve the survival rate after recurrence. key. Interventional treatment is an important means of non-surgical treatment in the comprehensive treatment of small hepatocellular carcinoma
