【摘要】 目的:观察经皮消融配合三维适形放疗治疗原发性肝癌的疗效。方法:45例原发性肝癌随机分成综合组和对照组。综合组21例,采用经皮消融三维适形放疗,对照组单用经皮消融。结果:综合组的局控率为85.7%,而对照组为58.3%,两者有显著性差异。1,2,3年的生存率综合组和对照组分别是81%,62.5%,25%;71.8%,33%,8%。两者差异有统计学意义。结论:原发性肝癌三维适形放疗结合经皮消融疗效较好。更多还原

【Abstract】 Objective:To evaluate the effect of three dimensional conformal radiation(3DCRT) with percutaneous ablation(PA) for unresectable primary hepatic carcinoma.Methods:Total of 45 patients with primary hepatic carcinoma were randomized to 2 groups:21 patients were treated with 3DCRT plus PA and the rest(control) were treated with PA only.For 3DCRT,radiation was given by 8MV-x-ray,patients received a total dose of 40-50Gy,5Gy per session every other day.Results:the 1,2,3 year survival rates of 3DCRT plus PA group and control group were 81%,62.5%,25% ;71.8%,33%,8%.The difference between the two groups was significant.The response rate(CR + PR) of 3DCRT plus PA and PA alone group were 85.7% and 58.3%.The difference was statistically significant.Conclusion:three dimensional conformal radiotherapy combined with PA is effecfive for unresectable primary liver cancer.更多还原
