摘要
目的:探讨食管支架置入术后放疗是否有助于患者生存期的延长或生活质量的提高。方法:对11例食管癌食管支架置入术后姑息放疗患者,与同期8例食管癌支架置入术后未放疗者进行对比。放疗经模拟机定位,15MVX线三野同中心照射,照射野长度包括食管支架全长及上下各放1～1.5cm,野宽6cm,常规分割,放疗总剂量为50～55Gy。结果:放疗者有明显不适的感觉(P=0.020),生存期或生活质量无明显改善,其它观察指标两组均无统计学意义。结论:晚期食管癌患者放疗前低营养状态不宜使用食管支架置入;对处于恶液质状态不宜放疗的患者,食管支架置入有姑息治疗价值,支架置入后不宜再行放疗。
Objective ：To investigate whether the radiotherapy after esophageal stenting can help enhancing the survival period or living-quality. Methods：For 11 patients, the radiotherapy fields were defined under imitation machine; the three fields concentric, 15 MV X-ray was taken ; the length of the fields included the total esophageal stent and 1 - 1.5 cm beyond the stent with the breadth at 6 cm; the total dose was 50 -55 Gy by convention fraction. Results：The radiotherapy did not extend the life span and living quality,and made the patients suffer more than the others. Conclusions ：The patients with advanced esophageal cancer should not undergo stenting to rectify low nourishment before radiotherapy. The patients after esophageal stenting should receive further radiotherapy.
