title: [Thyroid cancer in patients with Grave's Disease].
abstract: OBJECTIVE
  To evaluate the incidence of thyroid carcinoma in patients operated on for Graves' disease, to identify criteria which may predict malignancy, and to develop a practical approach to determine the extensiveness of thyroidectomy.
  
  
  METHODS
  Retrospective study of all patients who underwent thyroidectomy for Graves' disease between 1995 and 2005.
  
  
  RESULTS
  547 patients underwent subtotal thyroidectomy for Graves' disease during this period. Post-operative pathology examination revealed six cases of thyroid cancer (1.1%). All six cases had differentiated thyroid carcinoma (papillary carcinoma in 3 cases, follicular carcinoma in 2 cases and papillo-follicular carcinoma in 1 case). The indication for initial thyroidectomy was a palpable thyroid nodule in 3 cases (50%), failure of medical treatment for Grave's disease in 2 cases (33%), and signs of goiter compression in 1 case (17%). Five patients underwent re-operative total thyroidectomy.
  
  
  CONCLUSIONS
  This study shows that while malignancy in Grave's disease is uncommon, the presence of thyroid nodule(s) in patients with Grave's disease may be considered as an indication for radical surgery. The most adequate radical surgery in this situation is to perform a total thyroidectomy.
