- Prophylactic central neck dissection (pCND) failed to reduce recurrence rates in patients undergoing total thyroidectomy for clinically node-negative papillary thyroid cancer (PTC).
Why this matters
- pCND has unclear benefit and a high complication rate in this patient population.
- Propensity-score matching generated patient groups without significant differences in age (P=.417), sex (P=.732), tumor size (P=.177), extrathyroidal extension (P=.777), lymphovascular invasion (P=.175), perineural invasion (P=.600), bilaterality (P=.758), multiplicity (P=.308), TNM stage (P=.120), or subtype (P=1.0).
- Patients who underwent pCND and those who did not had similar recurrence rates (2.96% vs 1.48%; P=.684), time to recurrence (71.5 vs 49.5 months; P=.355), and 5-year recurrence-free survival (97.2% vs 98.1%; P=.571).
- 477 patients with clinically node-negative PTC measuring
- Propensity-matched cohorts of 135 patients who underwent pCND vs 135 who did not.
- Funding: None disclosed.
- Retrospective study design.
- 88.5% of tumors were
