Dilemma of clinically node-negative head and neck melanoma: Outcome of 'watch and wait' policy, elective lymph node dissection, and sentinel node biopsy - A systematic review

摘要

The management of patients with clinically nodenegative melanoma of the head and neck remains controversial. This is a systematic review of management strategies for stage 1 head and neck melanoma. Subgroup analysis of 1 randomized controlled trial (RCT) and most available cohort studies do not reveal a significant impact of elective neck dissection on survival. For 1.2- to 3.5-mm-thick melanoma at all anatomical sites, 1 RCT does not show an overall significant melanoma-specific survival benefit of sentinel node biopsy, but subgroup analysis suggests a survival benefit for lymph node-positive patients, confirming findings from 3 retrospective series. Sentinel node biopsy in the head and neck region can be technically demanding, with lower identification rates and higher false-negative rates. There is no conclusive survival advantage of either elective neck dissection or sentinel node biopsy in patients with clinically nodenegative head and neck melanoma of intermediate thickness.
