Primary Excision Margins and Sentinel Lymph Node Biopsy in Cutaneous Melanoma

This is a clinical practice guideline for adults diagnosed non-metastatic cutaneous melanoma, located on the trunk, extremities, or head and neck. The guideline examines optimal excision margins and the use of sentinel lymph node biopsy (SLNB) in these patients. The recommendations are organized by location of melanoma on the body, and consider the thickness/depth of the melanoma. Outcomes of interest include recurrence rate, survival rate, morbidity, and rate of sentinel lymph node positivity.
