Abstract
Patients (1164) with stage I melanoma of the skin who were submitted to wide excision only of the primary tumor were studied to evaluate the rates of regional lymph node and distant metastases. Of these, 516 (44.3%) had a recurrence of the disease which was at regional lymph nodes in 264 (22.7%), at distant sites in 91 (7.8%), and simultaneously at regional lyhmph nodes and distant sites in 161 (13.8%). Most of the patients had a relapse within 5 yr: regional node metastases were most frequently observed during the first 3 yr, and distant metastases appeared later. The ratio regional:distant metastases was not different (P > 0.05) when subgroups of patients were considered according to prognostic criteria (sex, site of origin, levels, thickness, ulceration). Sex, levels, thickness and ulceration were found to be significantly related with the frequency of recurrences (regional and distant). The prognostic criteria considered do not predict whether the tumor will metastasize to regional nodes or to distant sites.
