Surgical Timing in Thyroid Cancer with Lateral Neck Metastases: Delayed Versus Contemporary Lateral Neck Dissection

Year: 2025

Type: article

Abstract: Backgrounds. Lateral neck dissection (LND) is standard for thyroid cancer patients with neck metastases, mostly performed at the same time as total thyroidectomy (cLND). We introduced a new delayed LND (dLND), 4 weeks after thyroidectomy to reduce surgical morbidity. This study aims to compare the oncologic/complication outcomes between the two strategies, based on a large retrospective cohort of patients. Methods. Between 1996 and 2024, 215 patients were treated with total thyroidectomy, central neck dissection (CND) and LND, and grouped by surgical strategy (cLND vs. dLND); survival/complication outcomes were analyzed and compared between the two groups. Results. The overall and disease-free survival were comparable between groups. Age, extracapsular extension, and nodal burden predicted recurrence. dLND was associated with a significantly lower risk of vocal fold palsy. Extranodal extension (ECE) strongly predicted nerve injury. Conclusions. dLND offers similar oncologic outcomes to cLND, with reduced risk of vocal fold palsy. A staged approach enhances nerve preservation and might be considered in treatment planning.
