“…[4][5][6] With minimal morbidity, SLN biopsy (SLNB; also known as sentinel lymph node dissection [SLND]) reliably detects subclinical nodal involvement, [7][8][9][10] provides accurate and cost-effective 11 staging, and identifies patients who may benefit from standard adjuvant or experimental therapy. 3,12 Whether SLNB confers a survival benefit awaits confirmation from several ongoing clinical trials, 13 including the Multicenter Sentinel Lymphadenectomy Trial, 7 the Sunbelt Melanoma Trial, 14 and the Florida Melanoma Trial. 15 A number of studies have sought to identify predictors of SLN status, with variable findings.…”
