Abstract
OBJETIVOS: Avaliar o papel da eletrocauterização como método adjuvante isolado na ressecção intralesional dos tumores ósseos benignos, levando em conta fatores associados à recorrência dessas lesões. MÉTODOS: Foram incluídos 47 pacientes com diagnóstico de tumores ósseos benignos que foram tratados com curetagem associada a eletrocauterização como método adjuvante. Os pacientes foram acompanhados por um tempo médio de 32,7± 19,4 meses e foi avaliada a taxa de recidiva em relação às seguintes variáveis: idade, sexo, localização do tumor, tipo histológico, estadiamento (B1, B2, B3), tamanho, tipo de material utilizado como preenchimento (PMMA ou enxerto ósseo). A taxa e o tipo de complicação pós-operatória também foram analisadas. RESULTADOS: A recidiva global foi de 19,1%, havendo correlação significante do grau do tumor em relação ao tempo de recidiva (p=0,028). Não foram observados outros fatores diretamente relacionados à recidiva local. CONCLUSÃO: A eletrocauterização mostrou-se um método simples, barato e eficaz no tratamento adjuvante dos tumores ósseos benignos. Nivel de Evidência IV, serie de casos.
Highlights
Benign bone tumors represent a heterogeneous group of bone lesions with variable histological characteristics and biological behavior
Initial studies showed that simple curettage presented high local recurrence,[4] especially in aggressive tumors
The aim of this study is to evaluate the results of isolated cauterization as a method adjuvant to the intralesional resection of benign bone tumors and the factors associated with the recurrence of these lesions, comparing its results with other methods described in literature
Summary
Benign bone tumors represent a heterogeneous group of bone lesions with variable histological characteristics and biological behavior Rarely lethal, they can result in important alterations of the bone architecture, causing mechanical fragility and destruction of the adjacent joints.[1] These tumors are classified by the histological aspect or by their behavior and aggressiveness, where the staging system proposed by Enneking et al.[2] that divides tumors into latent (B1), active (B2) and aggressive (B3) is used the most often.
