| 摘 要： | 目的 比较乳腺癌调强放疗计划的正向和逆向2种设计模式的区别。方法 针对6例左侧乳腺癌保乳术后的患者应用Pinnacle37.4f计划系统,分别设计正向和逆向调强放疗计划,在射野方向相同、保证处方剂量线包绕95%靶区体积的前提下,比较2种计划的剂量体积直方图参数和加速器总跳数。结果 2种调强计划相比,正向及逆向调强计划的计划靶区体积适形度指数值分别为0.67±0.06和0.66±0.06(t=2.423,P>0.05),均匀性指数值分别为(28.2±6.0)%和(26.1±6.8)%(t=2.164,P>0.05);左肺V20分别为(18.7±3.3)%和(17.0±2.8)%(t=5.087,P<0.05),V30分别为(15.5±3.0)%和(14.0±2.6)%(t=7.272,P<0.05);心脏V30分别为(4.1±3.1)%和(3.5±2.5)%(t=1.916,P>0.05);机器跳数分别为(262±5)MU和(308±14)MU(t=7.515,P<0.05)。结论 与正向调强放疗计划相比,乳腺癌逆向调强计划中靶区适形度和均匀性无差别,左肺受量降低,心脏受量无差别;但机器跳数显著增加,增加了机器的磨损和治疗实施时间。
