The effects of negative regional lymph-node dissection on survival and disease-free interval of patients with stage-I malignant melanoma.

Abstract

A group of 46 patients, with stage-1 malignant melanoma of intermediate thickness and histologically proven negative regional lymph nodes, was retrospectively reviewed. The aim of our study was to determine whether the prognosis of these patients had been worsened by the regional lymph-node dissections. There was no influence on the survival or disease-free interval.
