Auto-immunité induite par l'interféron à faible dose dans le mélanome stade I

Many studies report the appearance of antinuclear antibodies, generally without clinical lesions during the treatment by interferon alpha for cancers (tumours carcinoids, hemopathies) and viral chronic hepatitis. Our study is, to our knowledge, the first evaluating the induction of an autoimmunity during the adjuvant treatment by interferon alpha of melanoma stage I. The induction of autoantibody during the treatment by interferon alpha could constitute a marker of effectiveness of the treatment with improvement of the survival of these patients. In our study, however auto immunity markers do not appear as factors of severity of evolution of the melanoma or predictive factors.
