Abstract
OBJECTIVE Leptomeningeal metastasis (LM) is a challenging scenario in non-small cell lung cancer (NSCLC). Considering that outcomes of treatment modalities stratified by LM chronological patterns related to brain metastasis (BM) are lacking, the aim of this study was to evaluate outcomes and explore prognostic factors. METHODS The authors retrospectively collected data of patients with NSCLC undergoing Ommaya reservoir implantation, ventriculoperitoneal shunt implantation, or lumboperitoneal shunt implantation. Based on radiographic findings and time from diagnosis of NSCLC to LM, the authors divided them into subtypes of LM as follows: LM without BM; LM concurrent with BM; or LM after BM. The Kaplan-Meier method was applied to analyze overall survival (OS) and multivariate Cox regression for prognostic factors. RESULTS Sixty-one patients with LM were included, with a median OS of 8.1 (range 0.2-70.0) months. Forty-three (70.5%) patients had EGFR-mutant disease. Forty-two (68.9%) patients had 19-del or L858R mutation, and one (1.6%) patient had G719A mutation. Fifty-seven (93.4%) patients had hydrocephalus. Twenty-one (34.4%) patients received whole-brain radiotherapy before LM diagnosis, 3 (4.9%) patients underwent operation for BMs before LM diagnosis, and 42 (68.9%) patients received EGFR tyrosine kinase inhibitor (TKI) therapy before LM diagnosis. Eleven patients were treated with chemotherapy, 10 patients were treated with TKIs, and 32 patients were treated with chemotherapy combined with TKIs before LM diagnosis. Patients with LM after BM had lower Karnofsky Performance Status (KPS) scores (KPS score 50) than did those with LM without BM (KPS score 80) or LM concurrent with BM (KPS score 70; p = 0.003). More patients with LM after BM received intrathecal methotrexate than in the other subgroups (p < 0.001). The median OS was significantly shorter in the LM after BM than in the concurrent LM and BM and the LM without BM subgroups (5.4 vs 5.5 vs 11.6 months; p = 0.019). Cox regression revealed that a KPS score ≥ 70 (HR 0.51; p = 0.027) and shunt implantation (HR 0.41; p = 0.032) were favorable prognostic factors. CONCLUSIONS Patients with NSCLC who had LM without BM had better survival outcomes (11.6 months) compared with those who had LM after BM or concurrent LM and BM. Aggressive shunt implantation may be favored for LM.

Lu VM, Abou-Al-Shaar H, Bin-Alamer O, Luther EM, Benjamin CG. Postoperative course of cerebrospinal fluid diversion in the setting of leptomeningeal disease: a systematic review, meta-analysis, and meta-regression with an illustrative case. J Neurooncol 2023; 163:29-37. [PMID: 37191912 DOI: 10.1007/s11060-023-04334-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 05/03/2023] [Indexed: 05/17/2023]
Abstract
BACKGROUND Management of hydrocephalus symptoms in the setting of leptomeningeal disease (LMD) includes cerebrospinal fluid (CSF) diversion, which can in the form of ventriculoperitoneal shunting (VPS) and lumboperitoneal shunting (LPS). However, the quantifiable postoperative course following this intervention is poorly defined. Correspondingly the aim of our study was to quantitatively define and analyze the pooled metadata regarding this topic. METHODS Multiple electronic databases from inception to March 2023 were searched following PRISMA guidelines. Respective cohort-level outcomes were then abstracted and pooled by means of meta-analyses and analyzed by means meta-regression, both utilizing random-effects modeling. Post-hoc bias evaluation was then performed for all outcomes. RESULTS A total of 12 studies were identified for inclusion, describing 503 LMD patients managed by CSF diversion - 442 (88%) by VPS and 61 (12%) by LPS. Median male percentage and age at diversion were 32% and 58 years respectively, with lung and breast cancer the most common primary diagnoses. Meta-analysis demonstrated pooled incidence of symptom resolution in 79% (95% CI 68-88%) of patients after index shunt surgery, and shunt revision required in 10% (95% CI 6-15%) of cases. Pooled overall survival from index shunt surgery was 3.8 mo (95% CI 2.9-4.6 mo) across all studies. Meta-regression demonstrated that studies published later trended towards significantly shorter overall survival from index shunt surgery (co-efficient=-0.38, P = 0.023), whereas the proportion of VPS to LPS in each study did not impact survival (P = 0.89). When accounting for these biases, overall survival from index shunt surgery was re-estimated to be shorter 3.1 mo (95% CI 1.7-4.4 mo). We present an illustrative case demonstrating the course of symptom improvement, shunt revision and an overall survival of 2 weeks from index CSF diversion. CONCLUSION Although CSF diversion in the setting of LMD can improve hydrocephalus symptoms in the majority of patients, there is a non-negligible proportion that will require shunt revision. Postoperatively, the prognosis of LMD remains poor irrespective of shunt type, and despite possible biases within the current literature, the expected median overall survival after index surgery is a matter of months. These findings support CSF diversion as an effective palliative procedure when considering symptoms and quality of life. Further research is required to understand how postoperative expectations can be managed to respect the best wishes of patients, their family, and the treating clinical team.

Abstract
BACKGROUND/AIM To review the current literature on pineal region gliomas, summarizing the clinical characteristics and treatment outcomes. MATERIALS AND METHODS PubMed, Scopus, and Cochrane databases were used to identify relevant articles. Comprehensive clinical characteristic review and survival analysis were conducted. RESULTS Twelve studies describing 81 patients were included. The median age was 39 years (male=54.3%). Fifty patients (61.7%) had obstructive hydrocephalus requiring cerebrospinal fluid diversion with either ventriculoperitoneal shunt (VPS) (40.0%) or endoscopic third ventriculostomy (ETV) (24.0%). Patients who underwent VPS had significant survival benefits compared to ETV (p<0.05). All patients in our review underwent surgery, and gross-total resection (≥98%) was achieved in 34.6%. The supracerebellar infratentorial approach was the most employed surgical approach (62.3%). Chemotherapy was administered in 32.1% of cases, and radiotherapy in 40.7%. The median overall survival (OS) was 12 months, and the overall one-year survival rate was 60%. CONCLUSION This study could not establish a correlation between the extent of tumor resection and positive treatment outcomes. However, among cases with hydrocephalus, patients who underwent VPS placement had better survival as compared to ETV.

Abstract
OBJECTIVE To investigate the outcomes of cerebrospinal fluid (CSF) diversion in lung cancer patients with leptomeningeal carcinomatosis (LMC). METHODS A retrospective review of consecutive lung cancer patients with LMC suffering from increased intracranial pressure (IICP) and hydrocephalus between February 2017 and February 2020. We evaluated the survival benefit of CSF diversion surgery and assessed the outcomes of treatments administered post-LMC in terms of overall survival and shunt-related complications. RESULTS The study cohort included 50 patients (median age: 59 years). Ventricular peritoneal (VP) shunts were placed in 33 patients, and lumbar peritoneal (LP) shunts were placed in 7 patients. Programmable shunts were placed in 36 patients. Shunt adjustment was performed in 19 patients. Kaplan-Meier analysis revealed that shunt placement increased overall survival from 1.95 months to 6.21 months (p = 0.0012) and increased Karnofsky Performance Scores (KPS) from 60 to 70. Univariate analysis revealed no difference between VP or LP shunts in terms of survival. No differences in post-shunt systemic treatments (tyrosine kinase inhibitors (TKIs) or systemic treatments) were observed in overall survival. Shunt-related complications were noted in 7 patients, including shunt obstruction (n = 4), infection (n = 1), and over-drainage (n = 2). CONCLUSION CSF diversion (VP or LP shunt) appears to be an effective and safe treatment for lung cancer patients with LMC and hydrocephalus. Programmable shunts should be considered for complex cases, which commonly require pressure adjustments as the disease progresses.

Abstract
OBJECTIVE Children with nonoperative brain tumors, such as diffuse intrinsic pontine gliomas (DIPGs), often have life-threatening hydrocephalus. Palliative shunting is common in such cases but can be complicated by hardware infection and mechanical failure. Endoscopic third ventriculostomy (ETV) is a minimally invasive alternative to treat hydrocephalus without implanted hardware. Herein, the authors report their institutional experience with palliative ETV for primary pediatric brain tumors. METHODS The authors conducted a retrospective review of consecutive patients who had undergone palliative ETV for hydrocephalus secondary to nonresectable primary brain tumors over a 10-year period at Rady Children's Hospital. Collected variables included age, sex, tumor type, tumor location, presence of leptomeningeal spread, use of a robot for ETV, complications, ETV Success Score (ETVSS), functional status, length of survival, and follow-up time. A successful outcome was defined as an ETV performed without clinically significant perioperative complications or secondary requirement for a new shunt. RESULTS Fifteen patients met the study inclusion criteria (11 males, 4 females; average age 7.9 years, range 0.8-21 years). Thirteen patients underwent manual ETV, and 2 patients underwent robotic ETV. Preoperative symptoms included gaze palsy, nausea/vomiting, headache, lethargy, hemiparesis, and seizures. Tumor types included DIPG (3), intraventricular/thalamic glioblastoma (2), and leptomeningeal spread of medulloblastoma (2), anaplastic oligo-/astrocytoma (2), rhabdoid tumor (2), primitive neuroectodermal tumor (1), ganglioglioma (1), pineoblastoma (1), and embryonal carcinoma (1). The mean preoperative ETVSS was 79 ± 8.8. There was 1 perioperative complication, a wound breakdown consistent with refractory hydrocephalus. The mean follow-up was 4.9 ± 5.5 months overall, and mean survival for the patients who died was 3.2 ± 3.6 months. Two patients remained alive at a mean follow-up of 15.7 months. Palliative ETV was successful in 7 patients (47%) and unsuccessful in 8 (53%). While patients with successful ETV were significantly older (11.9 ± 5.6 vs 4.4 ± 4.1 years, p = 0.010), there were no significant differences in preoperative ETVSS (p = 0.796) or postoperative survival (p = 0.476) between the successful and unsuccessful groups. Overall, functional outcomes were similar between the two groups; there was no significant difference in posttreatment Karnofsky Performance Status scores (68.6 ± 19.5 vs 61.3 ± 16.3, p = 0.454), suggesting that including ETV in the treatment algorithm did not worsen outcomes. CONCLUSIONS Palliative ETV is a safe and potentially efficacious treatment option in selected pediatric patients with hydrocephalus from nonoperative brain tumors. Close follow-up, especially in younger children, is required to ensure that patients with refractory symptoms receive appropriate secondary CSF diversion.

Abstract
Recent therapeutic advances involving the use of systemic targeted treatments and immunotherapeutic agents in patients with advanced cancers have translated into improved survival rates. Despite the emergence of such promising pharmacological therapies and extended survival, the frequency of metastases in the central nervous system has steadily increased. Effective medical and surgical therapies are available for many patients with brain metastases and need to be incorporated into multi-disciplinary care protocols. The role of neurosurgeons is evolving within these multi-disciplinary care teams. Surgical resection of brain metastases can provide immediate relief from neurological symptoms due to large lesions and provides the histopathological diagnosis in cases of no known primary malignancy. In situations where immunotherapy is part of the oncological treatment plan, surgery may be proposed for expeditious relief of edema to remove the need for steroids. In patients with multiple brain metastases and mixed response to therapeutics or radiosurgery, tumour resampling allows tissue analysis for druggable targets or to distinguish radiation effects from progression. Ventriculo-peritoneal shunting may improve quality of life in patients with hydrocephalus associated with leptomeningeal tumour dissemination and may allow for time to administer more therapy thus prolonging overall survival. Addressing the limited efficacy of many oncological drugs for brain metastases due to insufficient blood-brain barrier penetrance, clinical trial protocols in which surgical specimens are analysed after pre-surgical administration of therapeutics offer pharmacodynamic insights. Comprehensive neurosurgical assessment remains an integral element of multi-disciplinary oncological care of patients with brain metastases and is integral to tumour biology research and therapeutic advancement.

Cerebrospinal fluid diversion for leptomeningeal metastasis: palliative, procedural and oncologic outcomes. J Neurooncol 2021; 154:301-313. [PMID: 34406564 DOI: 10.1007/s11060-021-03827-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Accepted: 08/11/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND Leptomeningeal metastasis (LM) occurs in 3-5% of patients with solid metastatic tumors and often portends a severe prognosis including symptomatic hydrocephalus and intracranial hypertension. Cerebrospinal fluid (CSF) shunting can provide symptomatic relief in this patient subset; however, few studies have examined the role of shunting in the palliation, prognosis and overall oncologic care of these patients. OBJECTIVE To identify and evaluate risk factors associated with prognosis after CSF diversion and assess surgical, symptomatic and oncologic outcomes in this population. METHODS A retrospective study was conducted on patients with solid-malignancy LM treated with a shunt at a NCI-designated Comprehensive Cancer Center between 2010 and 2019. RESULTS One hundred and ninety patients with metastatic LM underwent CSF diversion. Overall survival was 4.14 months from LM diagnosis (95% CI: 3.29-4.70) and 2.43 months (95% CI: 2.01-3.09) from shunting. Karnofsky performance status (KPS) at time of shunting and brain metastases (BrM) number at LM diagnosis demonstrated significant associations with survival (HR = 0.66; 95% CI [0.51-0.86], p = 0.002; HR = 1.40; 95% CI [1.01-1.93] per 10 BrM, p = 0.04, respectively). Eighty-three percent of patients experienced symptomatic relief, and 79% were discharged home or to rehabilitation facilities post-shunting. Post-shunt, 56% of patients received additional systemic therapy or started or completed WBRT. Complications included infection (5%), symptomatic subdural hygroma/hematoma (6.3%), and shunt externalization/removal/repair (8%). Abdominal seeding was not identified. CONCLUSIONS CSF diversion for LM with hydrocephalus and intracranial hypertension secondary to metastasis can achieve symptomatic relief, hospital discharge, and return to further oncologic therapy, with a complication profile unique to this pathophysiology. However, decision-making in this population must incorporate end-of-life goals of care given limited prognosis.

Abstract
The characteristics of hydrocephalus associated with cerebellar glioblastoma (cGB) remain poorly known. The objectives were to describe the occurence of hydrocephalus in a French nationwide series of adult patients with cGB, to identify the characteristics associated with hydrocephalus and to analyze the outcomes associated with the different surgical strategies, in order to propose practical guidelines. Consecutive cases of adult cGB patients prospectively recorded into the French Brain Tumor Database between 2003 and 2017 were screened. Diagnosis was confirmed by a centralized neuropathological review. Among 118 patients with cGB (mean age 55.9 years), 49 patients (41.5%) presented with pre-operative hydrocephalus. Thirteen patients (11.0%) developed acute (n=7) or delayed (n=6) hydrocephalus postoperatively. Compared to patients without hydrocephalus at admission, patients with hydrocephalus were younger (52.0 years vs 58.6 years, p=0.03) and underwent more frequently tumor resection (93.9% vs 73.9%, p=0.006). A total of 40 cerebrospinal-fluid diversion procedures were performed, including 18 endoscopic third ventriculostomies, 12 ventriculoperitoneal shunts and 10 external ventricular drains. The different cerebrospinal-fluid diversion options had comparable functional results and complication rates. Among the 89 patients surgically managed for cGB without prior cerebrospinal-fluid diversion, 7 (7.9%) were long-term shunt-dependant. Hydrocephalus is frequent in patients with cGB and has to be carefully managed in order not to interfere with adjuvant oncological treatments. In case of symptomatic hydrocephalus, a cerebrospinal-fluid diversion is mandatory, especially if surgical resection is not feasible. In case of asymptomatic hydrocephalus, a cerebrospinal-fluid diversion has to be discussed only if surgical resection is not feasible.

Abstract
Treatment options for hydrocephalus include endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS). Some ambiguity remains regarding indications, safety, and efficacy for these procedures in different clinical scenarios. The objective of the present study was to pool the available evidence to compare outcomes among patients with hydrocephalus undergoing ETV versus VPS. A systematic search of the literature was conducted via PubMed, EMBASE, and Cochrane Library through 11/29/2018 to identify studies evaluating failure and complication rates, following ETV or VPS. Pooled effect estimates were calculated using random effects. Heterogeneity was assessed by the Cochrane Q test and the I2 value. Heterogeneity sources were explored through subgroup analyses and meta-regression. Twenty-three studies (five randomized control trials (RCTs) and 18 observational studies) were meta-analyzed. Comparing ETV to VPS, failure rate was not statistically significantly different with a pooled relative risk (RR) of 1.48, 95%CI (0.85, 2.59) for RCTs and 1.17 (0.89, 1.53) for cohort studies; P-interaction: 0.44. Complication rates were not statistically significantly different between ETV and VPS in RCTs (RR: 1.34, 95%CI: 0.50, 3.59) but were statistically significant for prospective cohort studies (RR: 0.47, 95%CI: 0.30, 0.78); P-interaction: 0.07. Length of hospital stay was no different, when comparing ETV and VPS. These results remained unchanged when stratifying by intervention type and when regressing on age when possible. No significant differences in failure rate were observed between ETV and VPS. ETV was found to have lower complication rates than VPS in prospective cohort studies but not in RCTs. Further research is needed to identify the specific patient populations who may be better suited for one intervention versus another.

Abstract
BACKGROUND Normal pressure hydrocephalus (NPH) is a critical brain disorder in which excess Cerebrospinal Fluid (CSF) is accumulated in the brain's ventricles causing damage or disruption of the brain tissues. Amongst various signs and symptoms, difficulty in walking, slurred speech, impaired decision making and critical thinking, and loss of bladder and bowl control are considered the hallmark features of NPH. OBJECTIVE The current review was aimed to present a comprehensive overview and critical appraisal of majorly employed neuroimaging techniques for rational diagnosis and effective monitoring of the effectiveness of the employed therapeutic intervention for NPH. Moreover, a critical overview of recent developments and utilization of pharmacological agents for the treatment of hydrocephalus has also been appraised. RESULTS Considering the complications associated with the shunt-based surgical operations, consistent monitoring of shunting via neuroimaging techniques hold greater clinical significance. Despite having extensive applicability of MRI and CT scan, these conventional neuroimaging techniques are associated with misdiagnosis or several health risks to patients. Recent advances in MRI (i.e., Sagittal-MRI, coronal-MRI, Time-SLIP (time-spatial-labeling-inversion-pulse), PC-MRI and diffusion-tensor-imaging (DTI)) have shown promising applicability in the diagnosis of NPH. Having associated with several adverse effects with surgical interventions, non-invasive approaches (pharmacological agents) have earned greater interest of scientists, medical professional, and healthcare providers. Amongst pharmacological agents, diuretics, isosorbide, osmotic agents, carbonic anhydrase inhibitors, glucocorticoids, NSAIDs, digoxin, and gold-198 have been employed for the management of NPH and prevention of secondary sensory/intellectual complications. CONCLUSION Employment of rational diagnostic tool and therapeutic modalities avoids misleading diagnosis and sophisticated management of hydrocephalus by efficient reduction of Cerebrospinal Fluid (CSF) production, reduction of fibrotic and inflammatory cascades secondary to meningitis and hemorrhage, and protection of brain from further deterioration.

Abstract
PURPOSE Leptomeningeal metastases (LM) are a rare, but often debilitating complication of advanced cancer that can severely impact a patient's quality-of-life. LM can result in hydrocephalus (HC) and lead to a range of neurologic sequelae, including weakness, headaches, and altered mental status. Given that patients with LM generally have quite poor prognoses, the decision of how to manage this HC remains unclear and is not only a medical, but also an ethical one. METHODS We first provide a brief overview of management options for hydrocephalus secondary to LM. We then apply general ethical principles to decision making in LM-associated hydrocephalus that can help guide physicians and patients. RESULTS Management options for LM-associated hydrocephalus include shunt placement, repeated lumbar punctures, intraventricular reservoir placement, endoscopic third ventriculostomy, or pain management alone without intervention. While these options may offer symptomatic relief in the short-term, each is also associated with risks to the patient. Moreover, data on survival and quality-of-life following intervention is sparse. We propose that the pros and cons of each option should be evaluated not only from a clinical standpoint, but also within a larger framework that incorporates ethical principles and individual patient values. CONCLUSIONS The decision of how to manage LM-associated hydrocephalus is complex and requires close collaboration amongst the physician, patient, and/or patient's family/friends/community leaders. Ultimately, the decision should be rooted in the patients' values and should aim to optimize a patient's quality-of-life.

Posterior Fossa Metastasis-Associated Obstructive Hydrocephalus in Adult Patients: Literature Review and Practical Considerations from the Neuro-Oncology Club of the French Society of Neurosurgery. World Neurosurg 2018; 117:271-279. [PMID: 29935321 DOI: 10.1016/j.wneu.2018.06.084] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Accepted: 06/13/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND There is no consensus concerning the management of adult patients with posterior fossa metastasis-associated obstructive hydrocephalus, especially regarding surgical procedures. A literature review was performed to assess the surgical strategy in the management of patients with metastatic brain tumor. METHODS A literature search was conducted of PubMed in November 2017 to identify all studies concerning brain metastases and obstructive hydrocephalus in English. All studies (except case reports and pediatric studies) between December 1953 and November 2017 that were about posterior fossa metastasis-associated obstructive hydrocephalus in adult patients were eligible. Eligible studies were classified by level of evidence. We assessed epidemiology, clinical and imaging findings, neurosurgical management, and prognosis of adult patients with posterior fossa metastasis-associated obstructive hydrocephalus. We suggest some practical considerations and a management decision tree on behalf of the Neuro-oncology Club of the French Society of Neurosurgery, with evidence-based analysis. RESULTS Direct surgical resection could be considered for patients with asymptomatic obstructive hydrocephalus, and endoscopic third ventriculostomy seems to be a reasonable procedure for patients with symptomatic obstructive hydrocephalus. A ventriculoperitoneal or atrial shunt seems to be a valid alternative when patients have a history of central nervous system infection or ventricular hemorrhage, leptomeningeal carcinomatosis, or unfavorable anatomy for an endoscopic third ventriculostomy to be performed. CONCLUSIONS The Neuro-oncology Club of the French Society of Neurosurgery suggests a prospective assessment of these neurosurgical procedures to compare their safety and efficacy.

Surg Neurol Int 2018; 9:112. [PMID: 29930878 PMCID: PMC5991270 DOI: 10.4103/sni.sni_387_17] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2017] [Accepted: 12/26/2017] [Indexed: 11/16/2022] Open
Abstract
Background: Approximately 20–30% of all intracranial metastases are located in the posterior fossa. The clinical evolution hinges on factors such as tumor growth dynamics, local topographic conditions, performance status, and prompt intervention. Fourth ventricle (V4) compression with secondary life-threatening obstructive hydrocephalus remains a major concern, often requiring acute surgical intervention. We have previously reported on the application of adaptive hypofractionated Gamma Knife Radiosurgery in the acute management of critically located metastases, a technique known to us as rapid rescue radiosurgery (3R). We report the results of 3R in the management of posterior fossa lesions and ensuing V4 decompression. Case Descriptions: Four patients with V4 compression due to posterior fossa metastases were treated with 3R by three separate gamma knife radiosurgical sessions (GKRS) over a period of seven days. Mean V4 volume was 1.02 cm3 at GKRS 1, 1.13 cm3 at GKRS 2, and 1.12 cm3 at GKRS 3. Mean tumor volume during the week of treatment was 10 cm3 at both GKRS 1 and 2 and 9 cm3 at GKRS 3. On average, we achieved a tumor volume reduction of 52% and a V4 size increase of 64% at the first follow-up (4 weeks after GKRS 3). Long-term follow-up showed continued local tumor control, stable V4 volume, and absence of hydrocephalus. Conclusion: For this series, 3R was effective in terms of rapid tumor ablation, V4 decompression, and limited radiation-induced toxicity. This surgical procedure may become an additional tool in the management of intractable posterior fossa metastasis with V4 compression.

Abstract
OBJECTIVES Leptomeningeal metastasis (LM) is associated with poor prognosis and affects the quality of life (QOL) of end-stage cancer patients. Severe headache associated with hydrocephalus causes reduced QOL. We investigated the clinical value of surgical treatment for hydrocephalus in LM patients. PATIENTS AND METHODS The medical records of 11 consecutive patients who underwent lumboperitoneal shunt (LPS) or ventriculoperitoneal shunt (VPS) at our institution between 2007 and 2016 were investigated. Primary brain tumor patients were excluded. We assessed the neurological status and therapeutic effects at 1 month after the shunt surgery. RESULTS The patients were three males and eight females with a median age of 58 years (interquartile range [IR] 52-68 years). The median preoperative neutrophil-to-lymphocyte ratio was 6.4 (IR 4.8-9.2). Symptom improvement was observed in nine patients, and severe headache was relieved in seven (88%) out of eight patients. The median Karnofsky performance status scale increased from 40 to 60, and the median overall survival after primary malignancy diagnosis was 27.4 months (IR 19.6-63.1 months). The median survival after the diagnosis of brain parenchymal metastasis, LM, and shunt surgery were 7.2 months (IR 5.1-14.1 months), 3.9 months (IR 3.5-6.3 months), and 3.3 months (IR 2.9-5.7 months), respectively. CONCLUSION Shunt surgery for hydrocephalus could offer an effective palliative surgical option for symptom relief especially relief of severe headache, contributing improvement of QOL in LM patients.

Abstract
Background: Sophisticated shunt valves provide the possibility of pressure adjustment and antisiphon control but have a higher probability of valve dysfunction especially in a posthemorrhagic setting. The aim of the present study is to analyze the clinical outcome of patients with shunt dependent posthemorrhagic hydrocephalus after aneurysmatic subarachnoid hemorrhage (SAH) in order to identify patients who would benefit from a simple differential pressure valve. Methods: From 2000 to 2013, 547 patients with aneurysmatic SAH were treated at our institution, 114 underwent ventricular shunt placement (21.1%). 47 patients with available pre- and post-operative computed tomography scans, and an available follow-up of minimum 6 months were included. In order to measure the survival time which a nonprogrammable differential pressure valve would have had in an individual patient we defined the initial equalized shunt survival time (IESS). IESS is the time until surgical revisions of fixed differential pressure or flow-regulated valves for the treatment of over- or under-drainage as well as re-programming of adjustable valves due to over- or under-drainage. Results: Twenty patients were treated with fixed differential pressure valves, 15 patients were treated with flow-regulated valves, and 12 underwent ventriculoperitoneal (VP) shunt placement with differential pressure valves assisted by a gravitational unit. Patients who reacted with remarkable changes of the ventricular width after the insertion of external ventricular drainage (EVD), before shunt placement, showed a significantly longer IESS. Conclusions: Decline of the ventricular width after EVD placement was a predictor for successful VP shunt therapy in the later course of disease. Possibly, this could allow identifying patients who benefit from a simple differential pressure valve or a flow-regulated valve, and thus could possibly avoid valve-associated complications of a programmable valve in the later course of disease.

Abstract
Approximately 1-5% of patients with cerebral metastasis and ~40% of patients with primary brain tumors suffer from hydrocephalus. These patients often exhibit a poor prognosis. The aim of the present study was to reassess the validity of ventriculoperitoneal shunting (VPS) with the assistance of the general surgeon in oncological patients. A total of 59 patients underwent first-time VPS at the Beth Israel Deaconess Medical Center (Boston, USA) between 2004 and 2012; 40 patients had hydrocephalus from brain metastasis and 19 from primary tumors. The analyzed independent variables included demographics, body mass index, past medical history, clinical presentation, indication for surgery, Karnofsky performance status (KPS) score and surgical technique; the dependent variables were postoperative symptoms and occurrence, cause and time of shunt failure. The outcomes were analyzed with the t-test and Kaplan-Meier estimates for shunt survival. The mean age of the patients was 57.2 years and the mean operative time was 50.4 min. Symptomatic palliation was achieved in 93% of the cases; patients with severe symptoms, such as debilitating headaches, nausea and vomiting, benefited significantly from VPS. The mean follow-up time was 6.3 months; complications occurred in only 7 patients (11.8%) during follow-up: 2 in the proximal shunt (1 infection and 1 obstruction), both requiring revision, 1 infection in the distal catheter requiring shunt removal, 2 cases of intracerebral bleeding that were monitored with computed tomography scans, 1 wound infection treated with antibiotics and 1 valve complication that required temporary revision. The initial and 3-month KPS scores were 65±16.4 and 75±16.0, respectively. The mean overall shunt survival was 6.4 months (range, 1.0 day-76.0 months) from the placement of the VP shunt. At 3 months after VPS, 93.5% of the patients remained alive with functioning shunts and at 1 year 87% of the shunts were still functioning. In conclusion, VPS remains a valid option for cancer patients with low KPS, as it improves the quality of life in such patients, even in the setting of previous infection, hemorrhage, or leptomeningeal disease, since shunt patency outlasts the overall survival of nearly all patients.

Abstract
There is a very wide range of applications in neurosurgery for the treatment of obstructive hydrocephalus by third ventriculostomy. To facilitate the operation, we measured the related data of transcallosal-interventricular foramen approach in endoscopic third ventriculostomy with the magnetic resonance images of the third ventricle from 103 healthy adults. We calculated the mean and standard deviation as well as the 95% confidence interval for the mean value of the measured data, which conformed to normal distribution. We used median and interquartile range to show its concentration and the level of variation when it does not.
