Therapeutic node dissections in malignant melanoma.

Abstract

In the absence of distant disease, therapeutic node dissections in malignant melanoma, i.e., dissections of regional nodal basins for palpable suspicious or biopsy-proven positive nodes, offer the chance of cure. The 5-year survival rates after therapeutic lymphadenectomy closely correlate with expected cure rates. Although they varied greatly in the literature, from 19% to 38%, the currently obtainable survival rates are in the upper ranges of this spectrum because patients now are closely followed-up and operated for early palpable nodal disease. Properly done, these procedures carry a low morbidity, but they should be done thoroughly to completely eradicate regional disease and avoid recurrences in the same nodal basin to achieve the maximum survival that is surgically attainable.
