Sentinel Node Biopsy in Primary Cutaneous Melanoma

This clinical practice guideline reviews the use of sentinel node biopsy (SLNB) as a diagnostic tool for adult patients with malignant melanoma. Topics of discussion include indications and contraindications of SLNB, pathological examination of the sentinel nodes, and indications for therapeutic node dissection and recommended extent of dissection. The use of ultrasound-guided fine-needle aspiration is also discussed. Outcomes of interest include test sensitivity, specificity, and positive and negative predictive value, as well as rate of nodal recurrence and survival.
