Long-Term Remission of Recurrent Brainstem Pilocytic Astrocytoma with Neuraxis Dissemination Using Recombinant Human Endostatin After Failure of Vincristine and Carboplatin.

Abstract

There is no standard salvage treatment for recurrent and/or unresectable brainstem low-grade gliomas after failure from carboplatin and vincristine chemotherapy. Recombinant human endostatin (rh-ES), a mild inhibitor of angiogenesis, has been used for treating lung cancer. But so far as we know, there is no experience for brainstem gliomas. The authors present a pediatric case of recurrent brainstem pilocytic astrocytoma with neuraxis dissemination who experienced tumor progression with carboplatin and vincristine chemotherapy but then had a dramatic and long-term remission for at least 29 months after combined treatment of rh-ES with carboplatin and vincristine. This case suggests that the addition of rh-ES to carboplatin and vincristine regimens may be synergistic and results in a long-term remission in patients with brainstem low-grade gliomas, even if the tumor is widely spread in the central nervous system.
