Sentinel node biopsy (SNB) is employed as standard treatment in some solid organ cancers to assess lymph node spread and enable targeted treatment. Several studies have investigated the role of SNB in thyroid cancer. This is a systematic review and meta-analysis of the role of SNB in the management of thyroid cancer. ⋯ SNB in thyroid cancer is a promising technique that has the potential to avoid prophylactic lymph node surgery in up to 57 per cent of patients with clinically node-negative thyroid cancer.
