Oncologic outcomes in patients with 1‐cm to 4‐cm differentiated thyroid carcinoma according to extent of thyroidectomy

Abstract

Although extent of thyroidectomy does not affect DSS, total thyroidectomy is beneficial for reducing recurrence in patients with 1-cm to 4-cm DTC. However, if such tumors have such low-risk features as being unifocal, intrathyroidal, and lymph node metastasis-negative, extent of thyroidectomy does not affect oncologic outcome and lobectomy may be sufficient.
