Abstract：Objective:To compare and evaluate the iodine 131 therapeutic effects on patients with abundant or poor residual thyroid tissues after surgery for papillary thyroid carcinomas.Method:56 patients in our hospital without apparent metastases and local invasion were treated with iodine 131 solutions by oral administration during 1-2 months after surgery for papillary thyroid carcinoma.Thyroid ultrasound was used to estimate the presences and the volumes of residual thyroid tissues before treatment.Thyroid hormone suppressive therapy were performed at 3 days after treatment.Iodine-131 whole body ECT imaging was first applied at 1 week after treatment and again used at 4-6 months after treatment.During the same time,ultrasound was used to estimate the presences of residual thyroid tissues and therapy effects were evaluated by the values of HTG.Result:After the treatment of iodine 131,the success rate of thyroid removal were 58.3333%(7/12) and 95.4545%(42/44) respectively in had or not had residual thyroid group,the difference was statistically significant(χ2=11.819,P=0.00).Conclusion:There is a correlation between remove the thyroid whether completely and residual thyroid size.Patients with incomplete clearance need to receive the second iodine 131 therapy for thyroid ablation.
