  4. Doppler ultrasound assessment: left ventricular ejection fraction (LVEF) ≥ 50%;
  5. Thyroid function is normal，defined as thyroid stimulating hormone (TSH) within normal limits. If baseline TSH is out of normal range, subjects with total T3 (or FT3) and FT4 within normal range can also be enrolled;
  6. Adequate organ function as judged clinically appropriate for the study by the physician.
* Subjects of childbearing potential must use adequate contraception during this study and for 120 days after the end of the study, have a negative serum pregnancy test within 7 days prior to study enrollment, and must be non-lactating.

Exclusion Criteria:

* Patients who had or currently had other malignant tumors within 3 years prior to the start of study treatment;
* Inability to perform (complete) brachytherapy due to anatomy, tumor shape, contraindications, etc.;
