Background Data: In following > 10,000 patients with cutaneous melanoma over the past 30 years, our institution has observed nodal or metastatic disease in approximately 15% of patients with a thin (45 years; P = 0.05), and Breslow thickness (>0.75 mm; P = 0.008) as significant negative prognostic characteristics. Of patients with these 3 high-risk characteristics, 19.7% developed advanced disease (likelihood ratio 6.3; P = 0.007 versus nonhigh-risk patients). This group had more than twice the incidence of nodal recurrences. Patients with recurrence had significantly decreased 10-year survival (82% versus 45%; P < 0.0001). Surprisingly, neither ulceration nor Clark level predicted advanced disease.Conclusions: Thin melanomas are potentially lethal lesions. Longterm follow-up identified a high-risk population of older males with tumors between 0.75 mm and 1.0 mm whose risk of recurrent disease approaches 20%. Traditionally accepted negative prognostic factors such as ulceration and discordant Clark levels are not predictive for metastasis in this population. Given the poor prognosis associated with recurrent disease, we recommend close clinical evaluation and follow-up to maximize accurate staging and therapeutic options.
