Two recent randomised studies found no survival difference in patients, who had melanoma with metastasis to the sentinel node (SN) and underwent immediate complete lymph node dissection (CLND), compared with patients, who were followed closely with ultrasound scans and only underwent CLND if metastases developed. From 2018, the Danish guidelines concur: SN-positive patients will no longer undergo routine CLND, which has high morbidity, but will be followed with ultrasound scans of the SN-positive region(s) at their follow-up visits every third month for two years, then every six month for three years, except if PET-CT is performed.
