Abstract
|
|
|
Purpose: External beam radiotherapy (EBRT) plays a controversial role in the management of differentiated thyroid cancer. We reviewed the outcomes of patients at our institution who had been treated with EBRT for advanced differentiated thyroid cancer.
Methods: Subjects included 35 patients who received thyroidectomy and EBRT at Yonsei University Wonju College of Medicine, Wonju Christian Hospital under the diagnosis of papillary thyroid cancer from January 1989 to September 2011.
Results: The 5 year overall locoregional control rate was 74.4%. No significant differences were found in locoregional progression- free survival for patients with complete resection, microscopic residual disease, or gross residual disease.
Conclusion: The results of our study have shown that EBRT is effective for locoregional control of selected locally advanced papillary thyroid cancer, even with gross residual disease.
