Cancer Management Chapter 23: Primary and metastatic brain tumors

March 11, 2010

Intracranial neoplasms can arise from any of the structures or cell types present in the cranial vault, including the brain, meninges, pituitary gland, skull, and even residual embryonic tissue. The overall annual incidence of primary brain tumors in the United States is 14 cases per 100,000 population.

Locoregional Therapies for Glioma

December 01, 2005

Glioma is the most common form of primary brain tumor, as well asthe most lethal. Primary treatment strategies for glioma, includingcytoreductive surgery, external-beam irradiation, and systemic chemotherapyhave had generally disappointing results for these tumors. Limitationsof these approaches include tumor invasion into functional braintissue, lack of chemosensitivity, and shortcomings of systemic delivery.Recent attention has focused on locoregional strategies for treatment,as well as new methods for delivering therapy. Identification of tumorspecificsurface targets, biologic agents, and more sophisticated meansto deliver macromolecules to the brain is offering new promise in thetreatment of these tumors. This paper will review the current state ofthe art of available locoregional therapies for glioma, with a particularfocus on convection-enhanced delivery, targeted toxin, and other biologicstrategies.
