Melanoma hereditário: prevalência de fatores de risco em um grupo de pacientes no Sul do Brasil

Abstract: FUNDAMENTOS: Aproximadamente 10% dos casos de melanoma são atribuíveis a mutações em genes de predisposição, sendo, portanto, hereditários. OBJETIVOS: Este estudo avalia a prevalência de fatores de risco para melanoma hereditário em um grupo de pacientes com melanoma no sul do Brasil. CASUÍSTICA E MÉTODOS: Foram estudados 195 pacientes com diagnóstico de melanoma admitidos consecutivamente no Hospital de Clínicas de Porto Alegre entre janeiro de 1999 e junho de 2000. RESULTADOS: A idade média ao diagnóstico de… Show more

“…2,24 It is estimated that 14% of patients who receive the diagnosis of melanoma show positive family history of this neoplasm. 8 Avilés et al 24 show that homogeneity in the HLA-DQA1 locus could probably be a potential predisposing factor for skin cancer in individuals exposed to other risks, both genetic and environmental.…”

“…7 In general, personal or family history of melanoma constitutes the greatest risk factor. 1,6,8 The use of photoprotectors as an effective protection measure has been widely discussed in the literature and is recommended for the prevention of all skin neoplasms. 5 In this study sun exposure and sun protection habits among university students were described.…”

“…[2][3][4] A média de idade foi de 51,3 anos, ratificando dados da literatura, que consagra adultos jovens como os mais susceptíveis para o melanoma. [4][5][6] Embora esses resultados sejam classicamente conhecidos, ainda não se sabe ao certo o motivo pelo qual o melanoma mostra a tendência de aumento das taxas de diagnóstico na meia-idade. De fato seria de esperar uma maior ocorrên-cia em faixas etárias mais avançadas, em virtude do efeito cumulativo da radiação solar e deterioração do sistema imune.…”

“…It is important to take into account that cancer is a multifactorial problem. It causes genetic mutations in cells, which are mostly related to family health history and exposure to ultraviolet (UV) ray [2,3]. UV radiation is the main risk factor for most type of skin cancer, such as melanoma type.…”
