| 摘 要： | 目的 比较乳腺癌术后胸壁大体积复发2野和6野调强放疗的计划差异.方法 对8例乳腺切除术后胸壁大体积复发病例,Pinnacle计划系统上分别对PTV进行2野调强和6野调强放疗计划设计,PTV处方剂量为50 Gy/25次(GTV后续计划补量至66～70 Gy),比较2种计划95％处方剂量PTV适形指数(CI)、均匀性指数(HI)及心脏、同侧肺剂量.结果 6野IMRT计划的CI和HI均优于2野IMRT计划,6野和2野的CI分别为(0.66±0.08)和(0.53±0.10)(t=7.99,P＜0.05),HI分别为(1.36±0.08)和(2.19±0.78)(t=9.04,P＜0.05).2个计划中肺V5、V10、V20、V35和心脏Dmax、V35、Dmean值比较差异无统计学意义.结论 乳腺癌切除术后胸壁大体积复发患者行放疗,6野静态逆向调强放疗计划靶区覆盖优于2野,而心肺受量方面无明显差异.
