A Phase II Study of External Beam Radiotherapy for Locoregionally Advanced or Recurrent Differentiated Thyroid Carcinoma
The standard approaches to the treatment of differentiated thyroid cancer include surgical
resection, radioactive iodine treatment, and thyroid-stimulating hormone suppression. The
role of external beam radiotherapy (EBRT), however, remains controversial.
The purpose of this phase II study is to evaluate the impact of EBRT on the locoregional
control in locoregionally advanced or recurrent differentiated thyroid cancer patients.
