非肿瘤性良性疾病的放射治疗

目的：探讨非肿瘤性良性疾病放射治疗的理想分割模式和剂量。方法：　以我科１９９６年９月至２０００年３月收治的３７例非肿瘤性良性疾病为研究对象，按照不同的时间一剂量分割模式和放射治疗总剂量分别比较其不同的１年治疗有效率。结果：本组资料总的１年治疗有效率为８３．８％。低分割模式组与小剂量分割模式组分别为８８．２％与７７．７％。低剂量组为７５％，高剂量组为９２％。结论：　放射治疗是非肿瘤性良性疾病的一种有效治疗方法，并存在这样的趋势，即低分割模式组与相对高剂量组的疗效分别优于小剂量分割模式组与相对低剂量组的疗效。

Radiation therapy in non-tumor benign disease

Objective: To explore the ideal radiation therapeutic fractionation regimen and total dose in non-tumor benign disease. Methods: 37 patients with non-tumor benign disease were administered with radiotherapy in our department between September, 1996 and March, 2000. According to the different time-dose fractionation regimen and total dose, we compared their different 1-year therapeutic response rate respectively. Results: The total 1-year therapeutic response rate was 83.8%. The low fractionation regimen group and small dose fractionation regimen group were respectively 88.2% and 77.7%. The high dose group was 92% and the low dose group was 75%. Conclusion: Radiation therapy is an effective measure of non-tumor benign disease, and there is a trend that the efficacy of the low fractionation regimen group and relatively high dose group are respectively more superior than that of the small dose fractionation regimen group and relatively low dose group.
