ABSTRACT
PURPOSE: To assess the importance of sentinel lymph node biopsy in patients with cutaneous melanoma. METHODS: Ninety consecutive non-randomized patients with stages I and II melanoma who underwent sentinel lymph node biopsy were followed up prospectively for six years. RESULTS: Patients were followed up for a mean period of 30 months. Their mean age was 53.3 years, ranging from 12 to 83 years. Thirty patients were male (37.5 percent) and 50, female (62.5 percent). Sentinel lymph node was positive in 32.5 percent and negative in 67.5 percent. It was found that the thicker the tumor, the greater the incidence of positive sentinel lymph nodes. In the group of patients with positive sentinel lymph nodes, recurrence occurred in 43.5 percent, but in those with negative sentinel lymph nodes, in only 7 percent, what points out to the association of tumor recurrence and positive sentinel lymph nodes. There were no major postoperative complications. CONCLUSION: Sentinel lymph node biopsy was demonstrated to be a safe method for selecting patients who need therapeutic lymphadenectomy.
RESUMO
OBJETIVO: Avaliar a importância da biópsia do linfonodo sentinela em pacientes com melanoma cutâneo MÉTODOS: Noventa pacientes com estadiamento I e II foram acompanhados prospectivamente no período de seis anos, de forma consecutiva e não randomizada e submetidos a biópsia do linfonodo sentinela. RESULTADOS: Os pacientes foram acompanhados durante tempo médio de 30 meses. A média de idade dos pacientes foi de 53,3 anos, variando de 12 a 83. Quanto ao sexo, foram avaliados 30 pacientes do sexo masculino (37,5 por cento) e 50 do sexo feminino (62,5 por cento).32,5 por cento dos pacientes apresentaram linfonodo sentinela positivo e 67,5 por cento linfonodo sentinela negativos. Comparando-se a espessura tumoral com a positividade do LS, verificou-se que quanto maior a espessura, maior a incidência de positividade do linfonodo sentinela. No grupo de pacientes com LS positivo a recorrência surgiu em 43,5 por cento dos casos, mostrando a relação entre a recorrência e a positividade do LS. Não houve complicações no pós-operatório. CONCLUSÃO: A biópsia do linfonodo sentinela mostrou-se um método seguro para selecionar os pacientes que necessitam de linfadenectomia terapêutica.
