PRRT
A targeted radiotherapy treatment for somatostatin receptor-positive neuroendocrine tumors.
Radioactive Iodine Therapy
Treatment using radioactive iodine (I-131) to destroy residual thyroid tissue or metastatic thyroid cancer cells.
radioiodine-refractory
Thyroid cancer that no longer concentrates radioactive iodine or progresses despite adequate radioiodine therapy.

Response Evaluation Criteria in Solid Tumors used to assess treatment response in neuroendocrine tumor clinical trials.
Recurrent Laryngeal Nerve
A branch of the vagus nerve that innervates most laryngeal muscles and is at risk during thyroid surgery.
regional nodal staging
Assessment of lymph node involvement in endocrine tumors to determine extent of disease and guide treatment decisions.
