RESUMEN

Introduction: The recurrence of cutaneous melanoma is one of the main reasons for surveillance after primary tumor treatment, and there is still little data on melanoma recurrence related to the Brazilian population. Objective: We sought to evaluate the profile of patients with cutaneous melanoma recurrence within five years of (early) and five years after (late) initial diagnosis. Methods: Patients diagnosed between 2006 and 2014 in a private reference service in Belo Horizonte, Brazil, were included. Demographic, clinical, histopathological, and disease evolution variables were collected and analyzed using the R version 4.0.0 program. A p-value less than 0.05 was considered significant. Results: The sample was composed of 331 patients with melanoma, and the 43 patients with recurrence presented with higher mean age (p=0.049), male predominance (p=0.030), a lower proportion of Breslow thickness under 0.8mm (p<0.001), and a more significant presence of mitosis (p=0.007). The 29 patients (8.8%) with early recurrence presented with tumors with ulceration (p<0.018). Late recurrence occurred in 14 patients (4.2%). Five patients relapsed after 10 years; most of them had tumors up to 1mm thick, without ulceration, regression, or satellitosis, but with the presence of mitosis. Conclusion: The possibility of cutaneous melanoma recurrence after five, and even 10, years, although rare, might indicate the need for longer medical follow-up. Multicenter studies may better characterize Brazilian patient profiles of those with early and late recurrence of melanoma.
