Antineuronal Antibodies in Patients with Neuroblastoma: Relationships with Clinical Features

We evaluated the frequency of serum antineuronal antibodies in a cohort of 39 neuroblastoma patients and related their presence to clinical features. Twelve patients displayed antineuronal antibodies at immunocytochemistry. Only one of these 12 patients suffered from a clinically overt paraneoplastic syndrome. No significant differences emerged between autoantibody-positive and autoantibody-negative patients in terms of progression-free and overall survival, although when only patients evolving to disease progression were considered, the time interval between diagnosis and progression was slightly longer in autoantibody-positive patients.
