Revisiting Factors Predisposing to Lateral Neck Node Metastasis in Differentiated Thyroid Cancer—a Clinical Audit

The importance of nodal metastasis in differentiated thyroid cancer (DTC) has always been considered to be minimal. However, guidelines do include a higher nodal burden and size of the metastatic node as a factor increasing the risk of recurrence. In this retrospective study, we looked at the incide...

Description
Summary:The importance of nodal metastasis in differentiated thyroid cancer (DTC) has always been considered to be minimal. However, guidelines do include a higher nodal burden and size of the metastatic node as a factor increasing the risk of recurrence. In this retrospective study, we looked at the incidence of lateral neck nodal metastasis (LNNM) in patients treated with DTC, the factors predisposing to the same nodal burden, and incidence of extranodal extension (ENE) in our cohort of patients. A total of 150 patients satisfied the inclusion criteria and were included in the study. The overall incidence of nodal metastasis was 63.3% ( n  = 95) and the incidence of LNNM was 58.7% ( n  = 88). The presence of central compartment nodal disease { p   3 cm frequently had ENE. There is a high rate of LNNM in DTC. Hence, thorough clinicoradiological evaluation of the neck is necessary before planning treatment for patients with DTC. The presence of central compartment nodal disease was the single most important factor predisposing to LNNM followed by the extrathyroidal extension.
