BACKGROUND: Melanoma is an immunogenic tumour type frequently associated with spontaneous auto-immune manifestations such as spontaneous regression, vitiligo-like reactions or auto-immune retinopathy, which seem to be associated with better prognosis. OBJECTIVES: The aim of this prospective study was to evaluate the correlation between spontaneous autoimmunity and survival in patients with stage IV melanoma. METHODS: From 2007 to 2008, 103 patients were studied with antithyroid and antinuclear auto antibody assays performed every 6 months. Any detectable occurrence of a spontaneous self antibody (SpSA) at the upper detection limit, at least for one assay, was considered to be a biological marker of autoimmunity. RESULTS: Univariate and multivariate analyses confirmed significantly longer survival in the absence of known primary melanoma (P = 0.044) and in the presence of marker of biologic autoimmunity, independently of previous immunotherapy (P = 0.045). CONCLUSIONS: This prospective and comparative study is, to our knowledge, the first to report the frequency of SpSA in stage IV melanoma. Our results suggest that spontaneous autoimmunity, through a rupture of self-tolerance, is a good prognostic factor in a subgroup of patients with stage IV melanoma.
