15例脊髓空洞症放射治疗疗效分析

目的：探讨放射治疗对脊髓空洞症的治疗作用。方法：回顾性分析1993年3月至2001年月该院共收治的15例脊髓空洞症患者的疗效，采用钴60或6MV X线或电子束照射，剂量21.6Gy，分次量为1.2Gy／次，每周5次。结果：完全恢复（CR）2例，好转（PR）8例，有效率66．7％，稳定（SD）3例，进展（PD）2例，全组均无明显放疗反应。结论：放射治疗是脊髓空洞症的一种重要的治疗方法，合并Chiari畸形及病程较长者疗效较差。

The Role of Radiotherapy for the Treatment of Syringomyelia in 15 Cases

To evaluate the role of radiotherapy for the treatment of syringomyelia.From March 1993 to March 2001, 15 patients with syringomyelia were retrospectively analyzed. All patients were treated by radiotherapy (Cobalt-60, 6MV photon or electron beam). The total radiation dose was 21.6Gy with 18 fractions of 1.2Gy.A complete clinical response was noted in two patients and a partial response in eight patients, which represents a 66.7% overall response rate. Three patients had stable diseases, and two patients had progressive disease. No severe toxicity was observed in the series.[Conclusion] Radiotherapy is one of the effective treatments for patients with syringomyelia, but it is less effective for those combined with Chiari aberrant or with longer course.
