title: Current therapy for brain tumors: back to the future.
abstract: In the last 30 years, while considerable progress has been made in laboratory research of malignant gliomas, fewer clinical breakthroughs can be highlighted. Laboratory research has improved our understanding of the biology, and especially the molecular genetics of this disease. Unfortunately, these successes highlight the difficulties in translating laboratory results into substantive clinical improvements. In part, these difficulties stem from a schizophrenic view of the development and evolution of brain tumors. We believe either that (1) brain tumors are local and therefore the most important research should have as its goal local control, or (2) brain tumors are diffuse, which is to say that the cells rapidly grow beyond their initial locus, and our research goal is the prevention or treatment of the advancing tumor front. Clearly both hypotheses have merit and, in fact, almost certainly, both are true. The question becomes, should we devote our research energies to one hypothesis at the exclusion of the other?
