【摘要】 目的:探讨瘢痕瘤切除术后放射治疗中采用不同分割方式的疗效。方法:回顾性分析1998年1月至2003年1月间86例瘢痕瘤切除术后在我科行放射治疗患者的疗效,按分割方式分为A组:12-15GY/2-3次,一周内完成。B组:12—15GY/3-5次,一周内完成。C组:12-15GY/6-8次,两周内完成。均于术后24小时开始放疗。结果:A、B、C组局部控制率分别为96.00%、90.00%、83.87%。组间比较均无统计学意义(P均>0.05),PAB=0.16;PAc=0.07;PBC=0.15。结论:瘢痕瘤术后放射治疗的总剂量以1O-20GY为宜,分割方式对疗效无明显影响。更多还原

【Abstract】 Objective To study the outcome of postoperative radiotherapy at same doses but in different fractions in patients with keloid .Methods 86 keloid cases who were treated with surgery and postoperative radiotherapy were analysed .The patients were divided into 3 groups according to the fraction. GroupA the patients received radiotherapy at the dose of 12-15 GY for 2-3 fractions in 1 week ;groupB:the same dose was delivered as groupA for 3-5 fractions in 1 week;Group Cthe patients received radiotherapy as the same dose as groupA and B for 6-8 fractions in 2 weeks. Results:the local control rate were 96.00%, 90. O0%and 83.87%,respectively. To compare A , B and C , The difference were not been shown statisticly between every two groups. (P>0.05) .Conclusion Different fractions can be used during radiotherapy in patients with keloid.更多还原
