摘要
目的 探讨放疗在骶尾部脊索瘤临床治疗中的作用。方法 采用常规分段治疗。第 1段DT4 0Gy/ 2 0次 / 4周 ,休 2周 ;第 2段DT30GY/ 15次 / 3周。随访 5年。 结果 16例骶尾部脊索瘤术后放疗或单纯性姑息放疗 ,不仅可使术后复发明显减少 (本组术后放疗复发率为 15 .38% ) ,而且使术后遗留症状得到改善 ,甚至消失。大剂量分段放疗的患者均未发生放射性损伤。结论 手术后放疗或单纯姑息性放疗能有效控制瘤体生长 ,延长生存期。
Objective To discuss and explore the clinical effect of radiotherapy for chordoma in sacrum caudal region.Methods Routine period radiotherapy:Primary stage : DT40GY/20 times/4 weeks,rest2 weeks ;Second stage :DT30GY/ 15 times / 3 weeks,5years' follow\|up.Results According to the 13 cases of Post\|operative radiotherapy for chordoma in sacrum caudal region and 3 cases of singly palliative radiotherapy,we find it can not only obviously decrease the post\|operation recurrence,but also improve the post\|operation symptoms. sometimes even no symptoms. ( In these 16 cases, the post\|operation recurrence rate is 15.38% .)No patients got radioactivity damage , after the large\|dose period radiotherapy.Conclusion Post\|operative radiotherapy or singly palliative radiotherapy can effectively control the growth of chordoma and prolong the patients' lives.The opinions that chordoma in sacrum caudal region are insensitive to radioactive rays need to be further discussed.
