[Indication for surgery in recurrent glioma of the brain].

In this paper, some aspects are discussed which are of importance for the indication for an operation because of gliomatous cerebral tumours. Among these, there are, for example, the histopathological findings, the patient's age, the period of anamnesis, and the time interval between the first operation and the recurrence, the degree of radical surgery for the removal of the tumour and the postoperative course as well as location and extension of the process. Problems of instrumental diagnosis of relapsing cerebral gliomas are briefly discussed. In conclusion, the paper gives a critical analysis of the results obtained in the surgery of glioma relapses.
