摘　　要：目的探讨甲状腺癌术后残留患者调强放射治疗的效果.方法对55例甲状腺癌术后残留患者行调强放疗,残存区域放疗剂量为66～70Gy,单次剂量2.15～2.25Gy.结果调强放射治疗后完全缓解（CR）率为69.1%（38/55）,部分缓解（PR）率为18.2%（10/55）.术后1、3、5年总生存率分别为96.4%、94.5%和85.5%,放射性皮炎1～2级占89.0%,3级占11.0%.结论调强放射治疗能有效控制甲状腺癌术后残留肿瘤,放疗毒副作用可控,是甲状腺癌术后残留的-种有效且安全的治疗手段.Objective To evaluate the efficacy of intensity-modulated radiotherapy( IMRT) for patients with postoperative residual of thyroid carcinoma. Methods 55 patients with postoperative residual of thyroid carcinoma were treated with intensity-modulated radiotherapy. The radiotherapy dose of residual area was 66 ~ 72 Gy,and 2. 15 ~ 2. 25 Gy each time. Results The complete remission( CR) was 69. 1%( 38 /55) and partial remission( PR) was 18. 2%( 10 /55). The overall 1-year、3-year and 5-year survival rates were 96. 4% 、94. 5% and 85. 5%,respectively. Conclusion Intensity-modulated radiation therapy can effectively control postoperative residual of thyroid carcinoma with tolerable side effects,and it is an effective treatment for thyroid cancer patients with postoperative residual.
