title: [Definition of limits and 3D configuration of cerebral gliomas. Histological data, therapeutic incidences (author's transl)].
abstract: In neurosurgical common practice, the only histological informations usually taken into account for the treatment of gliomas are the histological type and degree of malignancy. Nevertheless, from a therapeutic point of view the spatial development of the tumor should be considered as a point of paramount importance. This spatial development can be evaluated in vivo with the help of C.T. scan and stereotaxic biopsic exploration. From the study of 150 astrocytic, oligodendrocytic or composed which have been explored by serial stereotactic biopsies, we tried to codify the histological informations so as to express, in a simple and practical way, both the histological type and malignancy together with the 3 D configuration of the tumor. This codification is a useful contribution to the choice of therapy, further more, it helps to assess and to compare therapeutic protocols on homogeneous tumor groups.
