Background:
Local control of metastases is critical to improving the life quality of patients with radioactive iodine-refractory (RAIR) thyroid cancer accompanying regional lymph node metastasis.
Case report:
The reported patient suffered from RAIR thyroid cancer accompanying poorly controlled cervical lymph node metastasis. The patient's lesions were controlled through 125I seed implantation combined with ultrasound-guided radio-frequency ablation (US-guided RFA). Such a combination therapy has not been reported to date.
Conclusion:
This study found US-guided RFA combined with 125I seed implantation to be safe and effective for the control of cervical local metastases in patients with RAIR thyroid cancer.
