| 摘 要： | 目的:探讨食管癌根治术后纵隔转移灶同时加量调强放疗的意义和效果.方法:39例食管癌根治术后发生纵隔转移患者,设定原发灶和预防照射区进行SIB-IMRT(simultaneous integrated boost intensity-modulated radiation therapy)计划设计.定义2个靶区:PTV1为需要加量照射的淋巴结靶区,给予69Gy(2.3×30次);PTV2为预防照射区,给予54Gy(1.8×30次)的剂量,设计等角度5野调强计划.结果:5野调强获得了满意的剂量分布,患者可在6周内完成治疗计划,所有患者完成了放疗,治疗后3个月复查CT,病灶达CR(complete response)占66.7%(36/54),PR(partial response)占 33.3%(18/54),总有效率(CR+PR)达到100.0%.结论:食管癌根治术后纵隔转移患者进行同时加量调强放射治疗物理学优势明显,可以明显提高局部控制率,急性放射治疗反应可耐受,具有良好的应用前景.
