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66～70 Gy，单次剂量2．15～2．25 Gy。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一种有效且安全的治疗手段。

Objective To evaluate the efficacy of intensity-modulated radiotherapy ( IMRT) for patients with postopera-tive residual of thyroid carcinoma .Methods 55 patients with postoperative residual of thyroid carcinoma were treated with inten-sity-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 effec-tively control postoperative residual of thyroid carcinoma with tolerable side effects , and it is an effective treatment for thyroid cancer patients with postoperative residual .
