目的 探讨小肝癌的介入治疗效果和影响因素。方法 用介入法治疗 42例小肝癌 ,并用COX回归模型对其进行生存分析。结果 ① 42例小肝癌肝动脉造影显示 2 6例肿瘤血管丰富 ,37例有肿瘤染色 ,其中 34例为结节状染色。②用Kaplan Meier法计算 42例小肝癌介入治疗后的 1,3 ,5年生存率分别为 88% ( 37/ 42 ) ,74% ( 31/ 42 ) ,5 1% ( 2 1/ 42 )。③Cox回归分析显示临床分期、分型和肿瘤灶内碘油沉积情况显著影响小肝癌的介入疗效。结论 ①小肝癌的诊断依据除肿瘤血管外 ,最重要的是结节状肿瘤染色。②小肝癌的介入疗效显著 ,应成为一项重要的非手术治疗方案
Objective To investigate the interventional treatment effect and influencing factors of small hepatocellular carcinoma. Methods Forty-two cases of small hepatocellular carcinoma were treated with interventional therapy and analyzed by COX regression model. RESULTS: Forty-two patients with small hepatocellular carcinoma underwent hepatic arteriography. Twenty-six patients had abundant tumor vessels and 37 patients had tumor staining. Of these, 34 patients had nodular staining. 2 The Kaplan Meier method was used to calculate the 1-, 3-, and 5-year survival rates of 42 cases of small hepatocellular carcinoma after interventional therapy were 88% (37/42), 74% (31/42), and 51% (2 1/42). 3Cox regression analysis showed that the clinical staging, classification, and deposition of lipiodol in the tumor foci significantly affected the interventional efficacy of small hepatocellular carcinoma. Conclusion 1 The diagnosis of small hepatocellular carcinoma is based on the removal of tumor vessels, the most important being the nodular tumor staining. 2 The interventional effect of small hepatocellular carcinoma is significant and should become an important non-surgical treatment plan.
