title: [Prognostic significance of perivascular round cell infiltrations in oligodendroglioma].
abstract: In 175 cases of oligodendroglioma (all grades, partly operated on several times), histological sections of the surgical material--in all, 226 preparations--were examined with regard to the presence and extent of lymphocytic infiltrates which could be assessed as manifestation of an immune reaction, and correlated with the clinical course. In case of infiltrates, the course was not more favourable than expected. Development of a tumour depends first of all on the inherent dynamics of the tumour itself. Prognosis can be favourably influenced by operation and possibly also by radiation.
