Cerebrospinal fluid enters the brain parenchyma from subarachnoid cisterns through perivascular Virchow-Robin spaces and passes into the interstitium through aquaporin channels in astrocytes. Then, cerebrospinal fluid removes metabolic products and mixes with interstitial fluid. Outflow of cerebrospinal fluid with metabolic products from the brain parenchyma occurs in three ways. The first route is periarterial through intermuscular spaces in the middle layer of cerebral arteries. The second route is perivenous. The third route is lymphatic through meningeal or sinus-associated lymphatic vessels. They provide drainage of macromolecules and immunocompetent cells from the brain to the cervical lymph nodes. Gliomas are accompanied by inhibition of normal cerebrospinal fluid outflow pathways, mainly due to additional intracranial tissue, and compensatory cerebrospinal fluid outflow along the spinal cord. Reduced cerebrospinal fluid release with impaired outflow contribute to accumulation of toxic metabolic products, proinflammatory cytokines and chemokines. Transport of antigens to lymph nodes is inhibited that disrupts antitumor immunity. Impaired cerebrospinal fluid circulation also reduces the effectiveness of intracranial drug delivery. One of the mechanisms of pathogenesis of glioma metastasis is based on migration of tumor cells along classical and meningeal lymphatic pathways. Damage to the latter contributes to metastasis.</p>","PeriodicalId":24032,"journal":{"name":"Zhurnal voprosy neirokhirurgii imeni N. N.

The median of overall survival is 16-17 months after comprehensive treatment. Among various difficulties for new therapeutic approaches, we should emphasize the blood-brain barrier complicating delivery of anti-cancer drugs to neoplasm and perifocal area. A promising approach is aptamer molecules as synthetic amino acid analogs capable of interacting and regulating activity of target proteins based on their spatial structural interactions. Aptamers possess high specificity and affinity to various receptors on cell surface and inside its structures if they penetrate cell membrane. In this review, we present various approaches to development of aptamer-based drugs against glioblastoma. Kopylov A.M. et al. synthesized a series of aptamers targeting EGFR and capable for delivery of toxic agents to tumor cells. Important clinical successes include the results of NOX-A12 drug and data on combined drugs based on trastuzumab in patients with metastatic breast cancer. NOX-A12 is an aptamer blocking <i>CXCL-12</i> gene and reducing resistance to irradiation of glioblastoma cells. Furthermore, very high control of breast cancer brain metastases in HER-2 positive cases was demonstrated for trastuzumab-emtansine and trastuzumab-deruxtecan. The last finding indicates the perspective for aptamer targeting glioblastoma tumor cells in conjugation with emtansine or deruxtecan.</p>","PeriodicalId":24032,"journal":{"name":"Zhurnal voprosy neirokhirurgii imeni N.

This study analyzed the experience with this regimen in the Radiotherapy Department of the Burdenko National Medical Research Center of Neurosurgery to evaluate the method's efficacy and safety. A retrospective analysis included patients who underwent radiation therapy between 2017 and 2020. The study included 73 patients. The median age was 56, and the male-to-female ratio was 1:5. Nine patients were diagnosed with schwannomatosis (neurofibromatosis type 2), and 12 had multiple meningiomas. A total of 94 meningiomas were treated with hypofractionation in regimens of 3 and 5 fractions. Twenty eight tumors (29.8%) were previously verified as WHO grade 1 (25) and grade 2 (3). The median target volume was 5.6 cm³ (range 0.2 to 28.9 cm³). Data for analysis were available for 60 patients with 80 tumors, which did not differ significantly in baseline characteristics from the entire group. The local 3-year and 5-year control rate for meningiomas was 95%. Local control did not differ between sporadic tumors and those associated with schwannomatosis and multiple meningiomas. Tumor control was not influenced by volume, number of fractions, dose, treatment platform, histological verification status, or tumor location (skull base vs. convexity). Radiation reactions within 12 months after treatment were detected in 5 tumors (6.3%). The presence of pre-existing peritumoral edema significantly increased the risk of radiation reactions to 60%. A reduction in meningioma size was observed in 61.3% of cases. The median tumor volume reduction was 37% (range 8-84%). This study identified 2 cases (2.5%) of radiation-induced pathomorphosis in the form of appearance and prolonged existence/progression of cysts, which is generally an uncharacteristic clinical course for meningiomas. Thus, hypofractionation is an effective and sufficiently safe method of radiation therapy for meningiomas, enabling the more frequent use of shortened radiation treatment courses instead of prolonged standard fractionation regimens. Given the rare recurrence of meningiomas and the low complication rate, larger and longer-term studies are needed to clarify all factors influencing the outcomes of radiation therapy.</p>","PeriodicalId":24032,"journal":{"name":"Zhurnal voprosy neirokhirurgii imeni N.
