    Abstract:
    Surgical resection of gliomas affecting functionally important brain structures is associated with high risk of permanent postoperative neurological deficit and deterioration of the patient's quality of life. The availability of modern neuroimaging and neuronavigation permits the application of minimally invasive stereotactic cryodestruction of the tumor in such cases. The authors used this treatment in 88 patients with supratentorial gliomas of various WHO histopathological grades not suitable for microsurgical resection. Postoperative mortality (1.1%) and rate of surgical complications (11.4%) were comparable to reported results of stereotactic brain tumor biopsy, whereas the rate of neurological morbidity (42%) was comparable to outcome after resection of gliomas within eloquent brain areas. The majority of complications were temporary, and permanent deterioration of neurological function was noted in 8% of cases only. The median survival after treatment in patients with glioblastoma and anaplastic astrocytoma was 12.4 and 46.9 months, respectively, and was not reached in cases of diffuse astrocytoma, which compared favorably both with historical controls and literature data. Therefore, it seems reasonable to consider stereotactic cryodestruction in multimodality management strategies of "unresectable" intracranial gliomas, and further studies directed at evaluation of its efficacy are definitely needed.
