【摘要】 目的　对Ⅰ、Ⅱ期乳腺癌施行保乳术后的病人进行根治性三维适形调强放射治疗,提高局部控制率,减轻放疗副作用,提高了生存质量。方法　2 0 0 4年4月～2 0 0 4年1 0月的1 1例接受过标准保存乳房手术的Ⅰ、Ⅱ期乳腺癌病人,均为女性,年龄31～4 6岁,平均34.7岁。术前触诊肿瘤大小为6mm～30mm ,术后病理结果为:单纯癌4例、浸润性导管癌5例、高分化管状腺癌1例、中分化腺癌1例。手术后三个月内接受三维适形调强放射治疗。乳房切线照射剂量4 7～5 0Gy/ 2 4～31次,局部电子线补量1 0～1 5Gy/ 5～8次。结果　全部病人顺利完成全程放疗,最长1例接受放疗后已经2年半,局部及全身未见复发征象,乳房外观形状良好,放疗反应轻微。结论　通过对Ⅰ、Ⅱ期乳腺癌病人进行三维适形调强放射治疗,达到了提高病人的生存质量,提高肿瘤控制率的目的。更多还原

【Abstract】 Objective The aim of three dimensional conformal radiation therapy, is to try to improve the quality of life, decrease the side effect and increase the tumor controlling rate of early-stage breast cancer.Methods From Apr. 2000 to Oct. 2004, 11 patients with early-stage breast cancer were treated by breast-conserving surgery and whole breast irradiation. All the patients were of stage Ⅰ or Ⅱ, and the age was 30 to 46(main 36.6). The dimension of primary tumor was less than 3cm. The three dimensional conformal radiation therapy following breast-conserving therapy is about one month after operation. The total dose of whole breast irradiation was 47～50Gy/24～31f and tangemial fields followed by 10～15Gy boost using suitable-energy electron beams.Results All patients had received irradiation process smoothly with none serious complication..Conclusion It can be concluded that through three dimensional conformal radiation therapy, early-stage breast cancer patients have obtained the better quality of life and ideal tumor controlling rate.更多还原
