Clinical Study on ^(131)I Ablation for Residual Normal Thyroid Tissues in Postoperative Differentiated Thyroid Carcinoma Patients

目的观察131I去除分化型甲状腺癌(DTC)术后残余组织的疗效。方法采用131I去除甲状腺癌术后残余组织115例,131I剂量为2.96~3.7GBq(80~100 mCi),服131I后3个月停用甲状腺片,改服三碘甲状腺原氨酸片50μg/d,连续15天,再停药15天以上,做全身131I显像。结果甲状腺癌术后残余组织去除率达70%。结论131I去除甲状腺癌术后残余组织的疗效较好,可以有效防止甲状腺癌的复发和转移。

Objective To explore the clinical values on 131l ablation for residual normal thyroid tissues in postoperative differentiated thyroid carcinoma （DTC） patients. Methods 115 patients of postoperative thyroid cancer were treated with 131I to ablate for residual normal thyroid tissues. 2.96 -3.7GBq of 131I ablative dose was administrated. Thyroid extract was given for 3 months, and then stopped. 50 p,g of T3 daily was given for 15 days and stopped for over 15 day. The 131I whole-body scan were performed. Results The effective rate of 131I ablation for residual normal thyroid tissues in postoperative was 70%. Conclusion The effect of 131I ablation for residual normal thyroid tissues in postoperative thyroid cancer patients is very good. It can prevent recur and discover transform of thyroid cancer patients.
