[Cytologic control of the resection margins of hemispheric gliomas and metastases].

Introduction: Postoperative MRI is the conventional method for assessing the radicalness of hemispherical tumors excision, but the method has limitations on sensitivity in the assessment of tumor infiltration of the peritumoral zone. The 'gold standard' for detecting tumor cells is the microscopic visualisation.

Aim: To study the possibilities of a cytological study of the excision margins of glial and metastatic tumors for an objective assessment of the radical nature of the operation.
