Topotecan in Pediatric Patients With Recurrent and Progressive Solid Tumors

Abstract

In previously treated patients, topotecan produced CRs and PRs in patients with neuroblastoma, Ewing's tumor, and retinoblastoma. In hepatoblastoma, rhabdomyosarcoma, and a few rare tumors, long-lasting MRs and SDs with excellent symptom control were seen. The toxicity of topotecan, predominantly myelosuppression, was tolerable.
