title: [On the systematic classification of oligodendrogliomas of grades I to III in tissue cultures (author's transl)].
abstract: We report on the in vitro behaviour of 71 oligodendrogliomas. This is the continuation of a systematic investigation on the morphology and biological behaviour of oligodendrogliomas, in line with the investigations of Kersting on the tissue culture of astrocytomas and their recurrences (1973). As reported elsewhere (Neumann et al.) we are able to show an extensive agreement between a histologically based system of grading and the biological behaviour (or follow-up pattern) of the oligodendrogliomas. It therefore seemed worthwhile to reconsider the tissue culture of these tumours, in order to see to what extent the histological classification shows simularities with the behaviour in vitro. One must particularly keep a careful eye on those cultures which come from a tumour which histologically was classified as Grade III, but whose follow-up corresponds much more to the pattern of more benign forms.
