Abstract
Objective: To evaluate the efficacy of low-dose of 30mCi I-131 (outpatient dose) to ablate residual thyroid tissue and serum thyroglobulin reduction in patients with low-risk differentiated thyroid cancer after total thyroidectomy at K Hospital. Subject and method: Retrospective study on 150 patients treated with 30mCi I-131 dose from January 2020 to June 2021. Result: The study included 139 female patients (93.7%), 11 male patients (7.3%), 27 to 74 years old, average 51 ± 10 years olds, 89 patients (59.3%) < 55 years old, 61 patients (40.7%) over 55 years old. Successful thyroid tissue ablation was achieved in 120 patients (80%), serum thyroglobulin before treatment was 2.33 ± 7.07ng/ml, after treatment was 1.20 ± 6.77, the reduction of serum thyroglobulin before and after treatment was statistically significant (p=0.006). Conclusion: Dose of 30mCi has a good efficacy for thyroid tissue remnant ablation for patients with low risk factors.
