1Department of Nuclear Medicine, Shanghai Sixth People's Hospital, Shanghai Jiao Tong University, Shanghai, China.
Objective:
To evaluate the clinical outcome in childhood patients receiving postoperative high-dose radioiodine therapy for advanced differentiated thyroid carcinoma.
Method:
Patients under 18 years old with neck diseases (n = 4) or distant metastases (n = 10) received postoperative radioiodine ablation and repeated treatments for a median of 2 (0.8 10) years with an averaged activity of 25.0 (7.0 72.2) GBq.
Results:
Partial remission was achieved in 6, stable disease in 6 and progressive disease in 2 patients, without severe side effects except for two Grade 1 and one Grade 2 WHO haematological toxicity. The median survival time from diagnosis to the last treatment sessions was 5.3 (range, 0.7 14.5) years.
Conclusion:
High-dose radioiodine treatment was well tolerated with satisfactory outcome in childhood patients with advanced differentiated thyroid carcinoma.
