BackgroundThe recent publication of randomized trials investigating the efficacy of adjuvant therapy and completion lymph node dissection at microscopic stage III melanoma calls for a reappraisal of melanoma management from different angles: indications for sentinel lymph node biopsy, indications for completion lymph node dissection in microscopic-stage disease, and adjuvant therapies. Our objective was to evaluate current practices and to question French onco-dermatologists about any changes they envisaged in their practices in the light of recent publications.MethodsWe conducted a national survey among members of the Cutaneous Oncology Group of the French Society of Dermatology in October 2017.ResultsForty French health centers were included, and 53 individual responses were collected. Sentinel lymph node biopsy for melanoma was performed at 75 % of the centers. Before the summer of 2017 and the publication of MSLT-II (proving the absence of any therapeutic benefits for complete lymph node dissection in microscopic stage III melanoma), when a positive sentinel lymph node was diagnosed, immediate completion lymph node dissection was performed at 90 % of the centers. After the publication of MSLT-II, 45 % of the respondents considered stopping this practice. The risk-benefit ratio prompted prescription of nivolumab and of combined dabrafenib+trametinib as adjuvant therapy by respectively 96 % and 79 % of respondents, while the corresponding rates for interferon and ipilimumab were only 21 % and 15 %.ConclusionEarly melanoma management stands on the verge of major changes thanks to the arrival of efficient adjuvant therapies and a decrease in immediate completion lymph node dissections for patients with microscopic stage III is also anticipated.Copyright © 2019.
