OBJECTIVES: I. Determine the safety in children of recurrent neuroblastoma of two weekly subcutaneous injections of autologous, or partially HLA-matched allogeneic, neuroblastoma cells that have been modified by insertion of the interleukin-2 gene introduced by a retroviral vector. II. Determine whether multiple histocompatibility-restricted or unrestricted antitumor immune responses are induced by this treatment and the cell dose required to produce these effects. III. Obtain preliminary data on the antitumor effects of this regimen.
