What role does external beam radiotherapy play in the treatment of well differentiated papillary thyroid cancer when a total thyroidectomy and lymph node dissection cannot be performed?
In the case of a partial resection with focal perineural invasion, but no lymphadenectomy due to severe fibrosis from prior radio-ablation for hyperthyroidism, is there a role for EBRT or additional RAI?
