Malignant brain tumors respond poorly to chemotherapy. This therapeutic resistance is the result of the marked heterogeneity of malignant gliomas in vivo and in vitro. Different factors, as specific markers, DNA distribution curves, morphology, chromosomal constitution, invasiveness and growth characteristics are considered for the understanding of the biology of malignant brain tumors. A better knowledge of this biology should provide new chemotherapeutic strategies.
