Chemotherapy of gliomas

Gliomas are usually incurable with current treatment regimens. The mainstay of current therapy is surgery and radiotherapy. Adjuvant chemotherapy with nitrosourea-based regimens for high-grade glioma has now been established as a means of improving survival times, although the results are disappointing and the treatment may entail significant morbidity and does not offer the prospect of cure. The role of chemotherapy for low-grade glioma is controversial, and its possible role as a primary therapy aimed at delaying the need for radiotherapy in young children must be better defined. The literature regarding chemotherapy of glioma is reviewed with particular emphasis on recent publications.
