A population-based study of the biology of the thin-level melanoma according to site, Breslow's thickness, and Clark's level was undertaken. Two hundred fifteen patients were studied with a mean follow-up of 41 months. Overall, 23 patients (10.7%) had recurrences, 8 locally, 9 regionally, and 6 systemically, despite an adequate local excision. A multivariate analysis was done. In the patients with thin lesions (less than 1 mm), increasing level (p < 0.002) and head and neck site (p < 0.04) increased the risk of recurrence. Increasing thickness of melanoma up to 1 mm did not influence the risk. This study identifies a group of high-risk melanoma patients for whom adjuvant therapy to decrease recurrences should be studied.
