摘 要:目的观察三维适形放疗(3DCRT)联合肝动脉化疗栓塞(TACE)治疗肝癌合并门脉癌栓(PVTT)的疗效。方法经过CT/MRI证实伴有门静脉癌栓的肝癌患者共145例,其中单纯手术64例(A组),接受TACE结合3DCRT治疗共81例(B组):大体肿瘤靶区(GTV)只包括癌栓,不包括原发灶,使90%等剂量曲线覆盖计划靶体积(PTV),照射总量45~60cGy,单次照射剂量2~4Gy。结果A组1、2年生存率分别为40.3%、21.9%,平均生存期15.2个月,有效率[完全缓解(CR)+部分缓解(PR)]为40.6%(28/64);B组1、2年生存率分别为41.2%、22.5%,平均生存期15.8个月,总有效率为44.4%(36/81),P〉0.05。结论TACE联合3DCRT与手术治疗肝细胞癌合并门脉癌栓的肝癌的疗效相近。Objective To explore the clinical therapeutic efficacies of combined three-dimensional conformal radiotherapy (3DCRT) plus transcatheter arterial chemoembolization (TACE) for portal vein tumor thrombus (PVTT) in hepatocellular carcinoma (HCC). Methods A total of 145 HCC patients with tumor thrombus in portal vein were divided randomly into 2 groups. Group A ( n = 64 ) was treated with surgical intervention alone while group B (n = 81 ) underwent 3DCRT plus TACE. The gross tumor volume (GTV) was defined as PVTF only. Results Survival rates of group A at year 1 and 2 were 40. 3% and 21.9% with a mean survival time (MST) of 15.2 months while that of group B were 41.2% and 22. 5% with a MST of 15.8 months. The total effective rates of groups A and B was 40. 6% (28/64) and 44. 4% (36/81) respectively. Conclusion The therapeutic efficacy of 3DCRT plus TACE is similar to that of surgical intervention.
