Abstract
Through retrospective analysis of patient records for 187 patients with melanoma seen between 1975 and 1989, the aim of this study was to determine whether outcome varied according to degrees of surgical intervention in the primary treatment of stage I disease for thin, intermediate, and thick lesions. There were no significant differences in recurrence rate associated with an excision margin of 15 mm or less compared with wider excision margins; with initial excision compared with wider re-excision after excision biopsy; or for primary closure as compared with closure with a graft. There was, however, a significant difference in wound complication rate between wounds closed primarily (6%) and those closed by grafting (31%) (p < 0.01). The authors advocate the more conservative excision margin of 1.00 cm to 1.50 cm in the treatment of stage I melanoma with primary closure of the wound where possible.
