OBJECTIVES: I. Determine the safety and toxicity of cellular immunotherapy using ex vivo expanded autologous CD8+ cytotoxic T-lymphocyte clones genetically modified to express the CE7R scFvFc:zeta chimeric immunoreceptor and the HyTK selection/suicide gene in children with recurrent or refractory disseminated neuroblastoma. II. Determine the antitumor activity of this regimen in these patients. III. Determine the duration of in vivo persistence of adoptively transferred clones and the effect of interleukin-2 on maintaining the in vivo persistence of these clones. IV. Screen for the development of host anti-scFvFc:zeta and HyTK immune responses in patients treated with this regimen. V. Determine the efficacy of ganciclovir in ablating transferred clones in vivo if toxicity occurs in these patients.
