BACKGROUND: The role of routine prophylactic central-neck lymph node dissection (CLND) for papillary thyroid cancer (PTC) remains controversial. We perform CLND for PTC only in patients with enlarged nodes as determined by preoperative ultrasound and intraoperative inspection and palpation.
METHODS: We identified all patients with PTC who underwent CLND during thyroidectomy (group 1) at our institution, and then we identified an equivalent number of demographically matched patients who underwent thyroidectomy without CLND (group 2) and compared the outcomes of the 2 groups.
RESULTS: In all, 191 patients were identified for each group; 49/191 (26%) patients in group 1 developed locoregional nodal recurrence (12% central neck and 21% lateral neck), compared with 11/191 (6%) patients in group 2 (3% central neck and 3% lateral neck; P < .05). Overall, 161/191 (84%) patients in group 1 were disease free at last survey, compared with 180/191 (94%) patients in group 2 (P < .05). Transient hypocalcemia was significantly greater in group 1. No difference was found in disease-specific mortality.
CONCLUSION: Surgeon assessment of the central neck compartment is an accurate predictor of which patients with PTC will benefit from CLND. Patients with nonenlarged central neck nodes who undergo total thyroidectomy without CLND have a low risk of developing recurrence.
