采用６０Ｃｏ外放射治疗原发性肝癌３０例，患者均为失去手术条件而肝功能正常的患者，Ⅱ期２３例，Ⅲ期７例，局部野照射１９例，肿瘤剂量２０００ＣＧｙ～６０００ＣＧｙ；全肝或半肝移动条加局部野照射１１例，肝脏中心平面剂量３１００ＣＧｙ～６０００ＣＧｙ。半年、１年、３年生存率分别为４６．６６％土９．１０％、３２．１４％土８．８１％及３．０６％土１４．０６。中数生存期５．８个月。影响疗效的主要因素是放射总剂量、临床分期、分型。 Thirty patients with primary hepatocellular carcinoma were treated with 60Co external beam radiotherapy. All of them were patients with normal hepatic function who lost the operation condition. There were 23 cases in stage Ⅱ, 7 cases in stage Ⅲ, 19 cases in local field irradiation and the dose of tumor was 2000CGy ~ 6000CGy. Elevated hemispheric movement and local field irradiation in 11 cases, the center of the liver dose of 3100CGy ~ 6000CGy. The six-year, one-year and three-year survival rates were 46.66% of the soil 9.10%, 32.14% of the soil 8.81% and 3.06% of the soil 14.06 respectively. The median survival of 5.8 months. The main factors affecting the efficacy of total radiation dose, clinical stage, type.
