“…In recent years, as the advances of neuroendoscope instruments and neuroendoscope technology, the application of neuroendoscope in ventricular lesions has expanded from biopsy of ventricular tumors to complete resection of ventricular tumors by neuroendoscope. Advantages of neuroendoscope include ( 9 – 11 ): 1) compared with the microsurgery, neuroendoscope provides a visual field that can be viewed directly and from multiple angles, with good illumination. It can effectively help identify the details of the tumor and the surrounding important tissues, improve the total tumor resection rate, and help avoid nerve function damage.…”

PurposeWe sought to reveal the clinical characteristics of lateral ventricle tumors and to evaluate the superior surgical procedure available.MethodsThere involved a total of of 49 adult patients harboring lateral ventricle tumors in neurosurgery department of our hospital from January 2016 to March 2022. The patients enrolled were retrospectively analyzed, so are their clinical manifestations, pathological characteristics and surgical strategies. The patients were allocated into neuroendoscope group (11 cases) and microsurgery group (38 cases) according to the operation method. The two groups underwent a detailed evaluation of operation effectiveness and safety profile (operation time, intraoperative bleeding, surgical resection rate, postoperative complications) and economic indicators (postoperative hospital stay, hospital costs).ResultsThe neuroendoscope group demonstrated a markedly shorter operation time than the microsurgery group (p<0.05), with the amount of bleeding significantly less than the microsurgery group (p<0.01). However, there was no significant difference in the resection rate and postoperative complications between the two groups (p>0.05). Significant difference was found in the economic indicators (postoperative hospital stay and hospital costs) of the patients in the neuroendoscope group (p<0.05).ConclusionSurgery intervention is regarded as the core treatment option for lateral ventricle tumors. Both microsurgery and neuroendoscopy are effective with safety profile. In the selected lateral ventricle tumor surgery, the application of neuroendoscopic surgery showed promising results, in terms of less intraoperative bleeding, and shorter operation time, postoperative hospital stays, and hospital costs. The selection of surgical approach and methods for lateral ventricle tumors is principally depended on the experience of neurosurgeon concerning the surgical approach and related neuroanatomy.

“…The combination of VBAS™ with other technology may also assist in resecting tumors in difficult locations. Akiyama et al used VBAS™ for a series of 16 patients with brain tumors, 2 of which were GBM [18]. A fixed endoscope was utilized for improved lesion visualization and to allow for bimanual resection techniques.…”

Glioblastoma (GBM) is malignant, primary intracranial neoplasm associated with poor outcomes. Maximal, safe cytoreduction remains an important component of effective treatment for patients with this disease; however, some patients are not candidates for resection due to comorbid status, tumor location, or other factors. In this review, we aimed to describe minimally invasive surgical techniques that are emerging as important tools for improving safety and efficiency in GBM cytoreduction, including for patients with previously unresectable lesions. Specifically, we aimed to describe the commercially available tubular retractor systems and describe the available data regarding the benefits, risks, and utility of these retractors for patients with GBM. Additionally, we aimed to describe laser interstitial thermal therapy (LITT) and its use in GBM, including a description of the mechanism of action, commercially available systems, the steps in surgical implantation, available outcomes data, and future directions for the technology in this context. Finally, we aimed to review the use of MRI-guided high-intensity focused ultrasound (MRgHIFU) in GBM, including a description of its mechanism and data regarding efficacy in GBM. The availability and use of tubular retractors, LITT, and MRgHIFU provide clinically effective alternative methods for cytoreduction in GBM and are also emerging as important tools for the expansion of treatment to GBM that previously may have been classified as nonresectable. This review will assist in the development of an intimate knowledge of the use and utility of these techniques and is important for clinicians caring for patients with GBM.

“…Glioma is the most common primary brain tumor with an incidence of 310/100 000 [1]. Deep-seated glioma refers to those localized far from the cortex and around the lateral ventricles, arising from thalamus, basal ganglion or corpus callosum [2,3]. These gliomas usually presented obvious symptoms, including hemiplegia, hemi-dysesthesia, even coma [4,5].…”

Objective The intracranial brachytherapy has been applied for decades, however, no results with long-term follow-up have been reported. This study investigated the long-term efficiency of intra-tumoral injection of 131I-chTNT in patients with deep-seated glioma. Method Thirty-five patients undergoing 131I-chTNT brachytherapy between December 2004 and May 2009 were enrolled. 131I-chTNT was injected at a dose of 1.5 mCi/cm3 at an interval of 1 month for consecutive 3 times. Serial ECT scan and MRI were performed during follow-up. Progression-free survival (PFS) and overall survival (OS) were analyzed. Adverse reactions were graded with WHO Toxicity Grading Scale for determining the severity of adverse events. Results ECT scan showed that enhanced accumulation of radioactive agents in the tumor lasted for more than 30 days. Three months after final injection, tumor complete remission (CR) was observed in 4 patients (11.4 %), partial remission (PR) in 11 cases (31.4 %), stable disease (SD) in 10 cases (28.6 %) and progressive disease (PD) in 10 cases (28.6 %). At 6-month, CR, PR, SD and PD were 2, 6, 12 and 15 respectively. After 10 years of follow-up, median progression-free survival (PFS) and overall survival (OS) were 5.4 and 11.4 months. One-year survival was 45.7 %, two and five-year survival was 8.6 %, ten-year survival was 5.7 %. Multivariate analysis showed that pathological grade and tumor diameter were independent prognostic factors for PFS and OS. Grade I–II adverse events occurred after drug injection, including nausea, fever, headache, hairloss and fatigue. Conclusion 131I-chTNT intracranial brachytherapy is efficient and safe for patients with deep-seated glioma. It is a reliable option for inoperable glioma patients.
