The Effect of Prophylactic Central Neck Dissection on Locoregional Recurrence in Papillary Thyroid Cancer After Total Thyroidectomy: A Systematic Review and Meta-Analysis

Abstract
The use of prophylactic central neck dissection (pCND) for papillary thyroid cancer (PTC) without clinical evidence of nodal metastasis (cN0) remains controversial. This study was designed to examine whether pCND for PTC affected locoregional recurrence (LRR).
