ReviewAdjuvant therapy of malignant melanoma and the role of sentinel node mapping.
Controversy still exists about standard management of a primary melanoma. Over the last decades randomized phase III trials have addressed questions about the width of margin in relation to the Breslow thickness of the primary lesion, the role of prophylactic isolated limb perfusion, and the role of elective lymph node dissection. Overall these trials have demonstrated that less extensive surgery is as good as more extensive surgery. Wide excision margins, prophylactic isolated limb perfusions, or the elective lymph node dissection did not improve overall survival significantly in any of the phase III trials conducted. ⋯ Thus we now have a procedure by which the melanoma stage I-II population can be dissected in a group at truly high risk for recurrence and a group with truly low risk of recurrence. The high risk group with a greater than 75% chance for systemic disease can then be selected for trial participation of various systemic adjuvant therapy regimens that may be allowed to be toxic, considering the very high risk for relapse in these patients. The node negative group of patients can be selected for participation in trials evaluating systemic adjuvant treatment of low toxicity considering the low chance for distant metastatic disease.
