Current status of therapy of solid tumors: brain tumor therapy.

Treatment of malignant brain tumors with conventional approaches is largely unsuccessful because curative doses generally cannot be delivered without excessive toxicity to normal brain. Radioimmunotherapy is emerging as an attractive alternative for glioma therapy because of the potential for more selectively irradiating tumor cells while sparing normal tissues. Several institutions are engaged in phase I and phase II trials investigating the therapeutic potential of monoclonal antibodies (mAbs) labeled with the beta-emitters (131)I and (90)Y and the alpha-emitter (211)At in patients with recurrent and newly diagnosed brain tumors. The current status of these trials will be discussed with regard to efficacy, toxicity, and future directions.
