中晚期食管癌陀螺刀放射治疗后影像学变化特点

Patients with Gyro Knife Radiotherapy after Imaging Change Characteristics

目的：探讨中晚期食管癌行陀螺刀放射治疗前后影像学变化，总结其影像学特点，分析其疗效。方法：回顾性分析2008年6月～2012年6月间中晚期食管癌行陀螺刀放射治疗前后造影复查的病人200例．分析其影像学变化．可分为：完全缓解、部分缓解、无效无变化、进展。结果：200例中CR（completeresponse）即完全缓解者120例．PR（partialresponse）即部分缓解者60例，NC（nochange）即无效．无变化者20例。没有发现PD（pregressofthediseases）即进展病例，20例无变化病例中出现并发症12例，分别是食管纵隔瘘2例．食管气管（或支气管）瘘8例．放射性肺炎2例．结论：通过观察200例中晚期食管癌放射治疗后的影像学变化，说明陀螺刀放射治疗中晚期食管癌是有效的．并且大部分治疗效果较好，但是有--／l,部分病人会出现食管气管（或支气管）瘘等并发症．应引起临床医生的重视。

Objective： To probe imaging change of middle-advanced stage esophageal carcinoma before and after radiation therapy by spinning top knife. Imaging characters were summarized. Curative effects were analyzed. Methods： 200 patients who were middle-advanced stage esophageal carcinoma before and after radiation therapy by spinning top knife were selected retrospective analysis in June 2008 to June 2012. Imaging change was analyzed： complete response, partial response, no change and progression. Results： 120 patients were complete response, 60 patients were partial response, 20 patients were no change, and no patient was progression among 200 patients. Complication was appeared in 12 patients among 20 patients who were no change： 2 patients was esophag-mediastinal fistula, 8 patients were esophage-trachea fistula, 2 patients was radiation pneumonia. Conclusion： It was effective middle-advanced stage esophageal carcinoma after radiation therapy by spinning top knife. Majority of patients were complete response. Minority of patients had complications. Clinicians should be reconstruction the complications.
