title: Changing concepts in the management of hereditary and sporadic medullary thyroid carcinoma.
abstract: Recent linkage of the gene for multiple endocrine neoplasia type 2A and 2B to the centromeric region of chromosome 10 has provided new insight into the causes of medullary thyroid carcinoma and has provided tools to diagnose gene carriers status for this syndrome with greater than 90% certainty. This review focuses on how these advances influence the clinical management of both sporadic and hereditary medullary thyroid carcinoma and discusses how tests based on the genetic linkage studies will aid in the early diagnosis and treatment of this syndrome. In addition, the authors have focused on several controversial management questions regarding the type and extent of surgery for this thyroid tumor, the management of the patient with metastatic disease, and the approach to management of other manifestations of multiple endocrine neoplasia types 2A and 2B. This review attempts to provide a balanced overview of these complex issues.
