Proportion of node-positive patients diagnosed by sentinel lymph node biopsy (true-positives). During follow-up, the sensitivity of SLNB steadily declines due to the occurrence of nodal recurrences in patients with an initially negative SLNB (FNs, A). Older age (B), the excision of only 1 SLN (C) and head or neck location of the primary melanoma (D) are associated with a lower sensitivity of SLNB and a higher FN rate, respectively. FNs = false-negative results, SLN = sentinel lymph node, SLNB = sentinel lymph node biopsy.
