ABSTRACT

Objective@#: The skull base reconstruction step, which prevents cerebrospinal fluid (CSF) leakage, is one of the most challenging steps in endoscopic skull base surgery (ESS). The purpose of this study was to assess the outcomes and complications of a reconstruction technique for immediate CSF leakage repair using multiple onlay grafts following ESS. @*Methods@#: A total of 230 consecutive patients who underwent skull base reconstruction using multiple onlay grafts with fibrin sealant patch (FSP), hydroxyapatite cement (HAC), and pedicled nasoseptal flap (PNF) for high-flow CSF leakage following ESS at three institutions were enrolled. We retrospectively reviewed the medical and radiological records to analyze the preoperative features and postoperative results. @*Results@#: The diagnoses included craniopharyngioma (46.8%), meningioma (34.0%), pituitary adenoma (5.3%), chordoma (1.6%), Rathke’s cleft cyst (1.1%) and others (n=21, 11.2%). The trans-planum/tuberculum approach (94.3%) was the most commonly adapted surgical method, followed by the trans-sellar and transclival approaches. The third ventricle was opened in 78 patients (41.5%). Lumbar CSF drainage was not performed postoperatively in any of the patients. Postoperative CSF leakage occurred in four patients (1.7%) due to technical mistakes and were repaired with the same technique. However, postoperative meningitis occurred in 13.5% (n=31) of the patients, but no microorganisms were identified. The median latency to the diagnosis of meningitis was 8 days (range, 2–38). CSF leakage was the unique risk factor for postoperative meningitis (p<0.001). @*Conclusion@#: The use of multiple onlay grafts with FSP, HAC, and PNF is a reliable reconstruction technique that provides immediate and complete CSF leakage repair and mucosal grafting on the skull base without the need to harvest autologous tissue or perform postoperative CSF diversion. However, postoperative meningitis should be monitored carefully.

ABSTRACT

Background@#There have been no guidelines for the management of adult patients with diffuse midline glioma (DMG), H3K27M-mutant in Korea since the 2016 revised WHO classification newly defined this disease entity. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, had begun preparing guidelines for DMG since 2019. @*Methods@#The Working Group was composed of 27 multidisciplinary medical experts in Korea.References were identified through searches of PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL using specific and sensitive keywords as well as combinations of keywords. As ‘diffuse midline glioma’ was recently defined, and there was no international guideline, trials and guidelines of ‘diffuse intrinsic pontine glioma’ or ‘brain stem glioma’ were thoroughly reviewed first. @*Results@#The core contents are as follows. The DMG can be diagnosed when all of the following three criteria are satisfied: the presence of the H3K27M mutation, midline location, and infiltrating feature. Without identification of H3K27M mutation by diagnostic biopsy, DMG cannot be diagnosed. For the primary treatment, maximal safe resection should be considered for tumors when feasible. Radiotherapy is the primary option for tumors in case the total resection is not possible. A total dose of 54 Gy to 60 Gy with conventional fractionation prescribed at 1-2 cm plus gross tumor volume is recommended. Although no chemotherapy has proven to be effective in DMG, concurrent chemoradiotherapy (± maintenance chemotherapy) with temozolomide following WHO grade IV glioblastoma’s protocol is recommended. @*Conclusion@#The detection of H3K27M mutation is the most important diagnostic criteria for DMG. Combination of surgery (if amenable to surgery), radiotherapy, and chemotherapy based on comprehensive multidisciplinary discussion can be considered as the treatment options for DMG.

ABSTRACT

Background@#To date, there has been no practical guidelines for the prescription of antiepileptic drugs (AEDs) in brain tumor patients in Korea. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, had begun preparing guidelines for AED usage in brain tumors since 2019. @*Methods@#The Working Group was composed of 27 multidisciplinary medical experts in Korea.References were identified through searches of PubMed, MEDLINE, EMBASE, and Cochrane CENTRAL using specific and sensitive keywords as well as combinations of the keywords. @*Results@#The core contents are as follows. Prophylactic AED administration is not recommended in newly diagnosed brain tumor patients without previous seizure history. When AEDs are administered during peri/postoperative period, it may be tapered off according to the following recommendations. In seizure-naïve patients with no postoperative seizure, it is recommended to stop or reduce AED 1 week after surgery. In seizure-naïve patients with one early postoperative seizure (<1 week after surgery), it is advisable to maintain AED for at least 3 months before tapering. In seizure-naïve patients with ≥2 postoperative seizures or in patients with preoperative seizure history, it is recommended to maintain AEDs for more than 1 year. The possibility of drug interactions should be considered when selecting AEDs in brain tumor patients. Driving can be allowed in brain tumor patients when proven to be seizure-free for more than 1 year. @*Conclusion@#The KSNO suggests prescribing AEDs in patients with brain tumor based on the current guideline. This guideline will contribute to spreading evidence-based prescription of AEDs in brain tumor patients in Korea.

ABSTRACT

Purpose@#We investigated the efficacy of temozolomide during and after radiotherapy in Korean adultswith anaplastic gliomas without 1p/19q co-deletion. @*Materials and Methods@#This was a randomized, open-label, phase 2 study and notably the first multicenter trial forKorean grade III glioma patients. Eligible patients were aged 18 years or older and hadnewly diagnosed non-co-deleted anaplastic glioma with an Eastern Cooperative OncologyGroup performance status of 0-2. Patients were randomized 1:1 to receive radiotherapyalone (60 Gy in 30 fractions of 2 Gy) (control group, n=44) or to receive radiotherapy withconcurrent temozolomide (75 mg/m2/day) followed by adjuvant temozolomide (150-200mg/m2/day for 5 days during six 28-day cycles) (treatment group, n=40). The primary endpointwas 2-year progression-free survival (PFS). Seventy patients (83.3%) were availablefor the analysis of the isocitrate dehydrogenase 1 gene (IDH1) mutation status. @*Results@#The two-year PFS was 42.2% in the treatment group and 37.2% in the control group. Overallsurvival (OS) did not reach to significant difference between the groups. In multivariableanalysis, age was a significant risk factor for PFS (hazard ratio [HR], 2.08; 95% confidenceinterval [CI], 1.04 to 4.16). The IDH1mutation was the only significant prognostic factor forPFS (HR, 0.28; 95% CI, 0.13 to 0.59) and OS (HR, 0.19; 95% CI, 0.07 to 0.50). Adverseevents over grade 3 were seen in 16 patients (40.0%) in the treatment group and werereversible. @*Conclusion@#Concurrent and adjuvant temozolomide in Korean adults with newly diagnosed nonco-deleted anaplastic gliomas showed improved 2-year PFS. The survival benefit of this regimenneeds further analysis with long-term follow-up at least more than 10 years.

ABSTRACT

Background@#High-grade glioma (HGG) with primary leptomeningeal seeding (PLS) at initial diagnosis is rare. The purpose of this study was to identify its clinical features and to describe the clinical treatment outcomes. @*Methods@#We retrospectively reviewed the medical records of patients with HGG (World Health Organization grade III or IV) at our institution between 2004 and 2019, and patients with PLS at the initial diagnosis were enrolled in the study. Clinical features, such as the location of leptomeningeal seeding, surgical methods, and degree of resection, were sorted based on electronic medical records also containing performance scale, and hematological and serological evaluations. Radiological findings and immunohistochemical categories were confirmed. Furthermore, we sought to determine whether controlling intracranial pressure (ICP) via early cerebrospinal fluid (CSF) diversion increases overall survival (OS) after the initial diagnosis. @*Results@#Of the 469 patients with HGG in our institution, less than 2% had PLS at the initial diagnosis. Most patients suffered from headache, diplopia, and dizziness. Pathological findings included 7 glioblastomas and 2 anaplastic astrocytomas. Seven of the 9 patients underwent CSF diversion. All patients were administered concurrent chemoradiotherapy (CCRT) with temozolomide, 89% of which started adjuvant temozolomide and 33% of which completed the six cycles of adjuvant temozolomide.The OS of patients with HGG and PLS was 8.7 months (range, 4-37), an extremely poor result compared to that of other studies. Also, the 1-year and 2-year OS rates were 44.4% and 16.7%, respectively. @*Conclusion@#Diagnosis and treatment of HGG with PLS are challenging. Aggressive control of ICP followed by early initiation of standard CCRT seems to be helpful in improving symptoms. However, despite aggressive treatment, the prognosis is poor. A multicenter trial and research may be necessary to create a standardized protocol for this disease.

ABSTRACT

Background@#: The Guideline Working Group of the Korean Society for Neuro-Oncology (KSNO)conducted a nationwide questionnaire survey for diverse queries faced in the treatment of brain tumors.As part I of the survey, the aim of this study is to evaluate national patterns of clinical practiceabout antiepileptic drug (AED) and steroid usage for management of brain tumors. @*Methods@#: A web-based survey was sent to all members of the KSNO by email. The survey included9 questions of AED usage and 5 questions of steroid usage for brain tumor patients. All questionswere developed by consensus of the Guideline Working Group. @*Results@#: The overall response rate was 12.8% (54/423). Regarding AED usage, the majority ofrespondents (95.2%) routinely prescribed prophylactic AEDs for patients with seizure at the peri/postoperativeperiod. However, as many as 72.8% of respondents prescribed AED routinely for seizure-naïvepatients, and others prescribed AED as the case may be. The duration of AED prophylaxis showedwide variance according to the epilepsy status and the location of tumor. Levetiracetam (82.9%) wasthe most preferred AED for epilepsy prophylaxis. Regarding steroid usage, 90.5% of respondents usesteroids in perioperative period, including 34.2% of them as a routine manner. Presence of peritumoraledema (90.9%) was considered as the most important factor determining steroid usage followed bydegree of clinical symptoms (60.6%). More than half of respondents (51.2%) replied to discontinue thesteroids within a week after surgery if there are no specific medical conditions, while 7.3% preferredslow tapering up to a month after surgery. @*Conclusion@#: The survey demonstrated the prevailing practice patterns on AED and steroid usagein neuro-oncologic field among members of the KSNO. This information provides a point of referencefor establishing a practical guideline in the management of brain tumor patients.

The survey included4 questions of diffuse midline glioma and 6 questions of meningioma (including 2 case scenarios).All questions were developed by consensus of the Guideline Working Group. @*Results@#: In the survey about diffuse midline glioma, 76% respondents performed histologicconfirmation to identify H3K27M mutation on immunohistochemical staining or sequencing methods.For treatment of diffuse midline glioma, respondents preferred concurrent chemoradiotherapy withtemozolomide (TMZ) and adjuvant TMZ (63.8%) than radiotherapy alone (34.0%). In the surveyabout meningioma, respondents prefer wait-and-see policy for the asymptomatic small meningiomawithout peritumoral edema. However, a greater number of respondents had chosen surgical resectionas the first choice for all large size meningiomas without exception, and small size meningiomaswith either peritumoral edema or eloquent location. There was no single opinion with major consensuson long-term follow-up plans for asymptomatic meningioma with observation policy. As many as68.1% of respondents answered that they would not add any adjuvant therapies for World Health Organizationgrade II meningiomas if the tumor was totally resected including dura. @*Conclusion@#: The survey demonstrates the prevailing clinical practice patterns for patients with diffusemidline glioma and meningioma among members of the KSNO. This information provides a pointof reference for establishing a practical guideline in the management of diffuse midline glioma andmeningioma.

ABSTRACT

Background@#: The Guideline Working Group of the Korean Society for Neuro-Oncology (KSNO)conducted the nationwide questionnaire survey for diverse queries facing to treat patients with braintumor. As part III of the survey, the aim of this study is to evaluate the national patterns of clinical practicefor patients with brain metastasis and primary central nervous system lymphoma (PCNSL). @*Methods@#: A web-based survey was sent to all members of the KSNO by email. The survey included7 questions of brain metastasis and 5 questions of PCNSL, focused on the management strategiesin specific situations. All questions were developed by consensus of the Guideline WorkingGroup. @*Results@#" In the survey about brain metastasis, respondents preferred surgical resection withadjuvant treatment for patients with a surgically accessible single brain metastatic lesion less than 3cm in size without extracranial systemic lesions. However, most respondents considered radiosurgeryfor surgically inaccessible lesions. As the preferred treatment of multiple brain metastases according tothe number of brain lesions, respondents tended to choose radiotherapy with increasing number of lesions.Radiosurgery was mostly chosen for the brain metastases of less than or equal to 4. In the surveyabout PCNSL, a half of respondents choose high-dose methotrexate-based polychemotherapy asthe first-line induction therapy for PCNSL. The consolidation and salvage therapy showed a little variationamong respondents. For PCNSL patients with cerebrospinal fluid dissemination, intrathecal chemotherapywas most preferred. @*Conclusion@#: The survey demonstrates the prevailing clinical practice patterns for patients withbrain metastasis and PCNSL among members of the KSNO. This information provides a point of referencefor establishing a practical guideline in the management of brain metastasis and PCNSL.

ABSTRACT

OBJECTIVE: Pituitary adenomas (PAs) are often detected as incidental findings. However, the natural history remains unclear. The objective of this study was to evaluate the natural history and growth pattern of untreated PAs.METHODS: Between 2003 and 2014, 59 PAs were managed with clinico-radiological follow up for longer than 12 months without any kind of therapeutic intervention. Tumor volumes were calculated at initial and last follow-up visit, and tumor growth during the observation period was determined. Data were analyzed according to clinical and imaging characteristics.RESULTS: The mean initial and last tumor volume and diameter were 1.83±2.97 mL and 13.77±6.45 mm, 2.85±4.47 mL and 15.75±8.08 mm, respectively. The mean annual tumor growth rate was 0.33±0.68 mL/year during a mean observation period of 46.8±32.1 months. Sixteen (27%) PAs showed tumor growth. The initial tumor size (HR, 1.140; 95% confidence interval, 1.003–1.295; p=0.045) was the independent predictive factor that determined the tumor growth. Six patients (11%) of 56 conservatively managed non-symptomatic PAs underwent resection for aggravating visual symptoms with mean interval of 34.5 months from diagnosis. By Cox regression analysis, PAs of last longest diameter over 21.75 mm were a significant prognostic factor for eventual treatment.CONCLUSION: The initial tumor size of PAs was independently associated with the tumor growth. Six patients (11%) of conservatively managed PAs were likely to be treated eventually. PAs of last follow-up longest diameter over 21.75 mm were a significant prognostic factor for treatment. Further studies with a large series are required to determine treatment strategy.

ABSTRACT

This report presents a case of fourth ventricle neurenteric cyst (NE cyst) mimicking hemangioblastoma, which developed in a 50-year-old woman. A tiny enhancing mural portion of the fourth ventricle in MRI suggested that the cyst was hemangioblastoma, but pathological evidence showed that the cyst was in fact NE cyst in the fourth ventricle. In order to make proper decision on to what extent of surgical resection should be done, considering every possibility in differential diagnosis might be helpful. This case reports an unusual pathology in 4th ventricle, considering the patient's age, and demonstrates that a rarer disease may share radiological features of a common disease.

ABSTRACT

BACKGROUND: The incidence of brain metastasis (BM) in gynecologic cancers has risen recently, due to prolonged survival times and an early diagnosis. We analyzed treatment outcomes of patients with BM from gynecologic cancers. METHODS: Among 951 patients with BM who were treated in neurosurgical department from July 2003 to February 2016, a total of 20 (2%) patients were from gynecologic cancers. The patients' clinical characteristics were collected by using medical records. There were 14 (66.7%) ovarian cancers, 4 (19.0%) uterine cancers, and 2 (9.5%) cervical cancers. As a primary treatment modality, 11 patients were treated with Gamma Knife surgery (GKS), 6 with surgical resection followed by whole brain radiation therapy (WBRT), and 3 with WBRT only. Overall and progression-free survival according to the primary origin and the primary treatment were analyzed. RESULTS: Median overall survival time was 28 months, and progression-free survival was 15 months. In patients with ovarian cancer, median overall survival did not reach during the follow-up periods and progression-free survival time was 15 months. Median overall survival time in patients who received GKS as the primary treatment was 17 months and that in patients who underwent surgical resection followed by WBRT was 37.3 months (p=0.16). The median value of progression-free survival time in patients who received GKS as the primary treatment was 12 months and that in patients who underwent surgical resection with WBRT was 42 months (p=0.042). Median follow up period of over all patients was 13 months. CONCLUSION: BM from gynecologic cancer is rare (2%), but our findings suggest that the prognosis might not always be poor. In our small series, surgical resection with WBRT was a treatment modality significantly associated with a longer progression-free survival. Additional studies with more cases and multi-institutional cooperation are needed to determine which treatment modality leads to better outcomes.

ABSTRACT

BACKGROUND: There have been various reports in the literature regarding the conservative management of pituitary apoplexy, pituitary incidentalomas and Rathke cleft cysts (RCCs). However, to the best of our knowledge, spontaneous involution of cystic sellar mass has rarely been reported. We report 14 cases of cystic sellar masses with spontaneous involution. METHODS: A total of 14 patients with spontaneous regression of cystic sellar masses in our hospital were included. The median age was 35 years (range, 5–67), and 8 patients were male. Clinical symptoms, hormone study and MRI were evaluated for all patients. The initial MRI showed all 14 patients with RCCs. Eight patients were presented with sudden onset of headache, and 1 patient with dizziness. Another patient, a 5-year-old child, was presented with delayed growth. Three patients had no symptoms via regular medical work up. All 14 patients had no visual symptoms. The follow-up period ranged from 5.7 to 42.8 months, with the mean of 17.3 months. RESULTS: The mean initial tumor size was 1.29 cm³ (range, 0.05 to 3.23). After involution, the tumor size decreased to 0.23 cm³ (range, 0 to 0.68) without any treatments. Repeated MRI showed a spontaneous decrease in tumor volume by 78% (range, 34 to 99). The initial MRI showed that the tumor was in contact with the optic chiasm in 7 patients, while compressing on the optic chiasm in 3 patients. Five patients were initially treated with hormone replacement therapy due to hormone abnormality. After the follow-up period, only 2 patients needed a long-term hormone replacement therapy. CONCLUSION: The spontaneous involution of RCCs is not well quantified before. Their incidence has not been well demonstrated, but this phenomenon might be underreported. Conservative management can be a treatment option in some RCCs without visual symptoms, even in those that are large in size and in contact with the optic nerve via imaging study.

ABSTRACT

OBJECTIVE: The authors evaluated the feasibility and targeting accuracy of CT fluoroscopy (CTF)-guided catheter placement and aspiration of intracerebral hematoma (ICH)s. MATERIALS AND METHODS: Nine patients (mean age, 63.3 +/- 15.3 years) were treated by CTF-guided hematoma aspiration under local anesthesia. The targeting errors in the lesion center, volume of the aspirated hematoma, accuracy of the final catheter position, procedure time, and clinical outcomes were evaluated. RESULTS: All catheters were successfully placed in the center of the hematoma. The mean volume of the aspirated hematoma was 20.6 +/- 8.8 mL (pre-treatment, 44.7 +/- 20.1 mL; post-treatment, 24.1 +/- 13.8 mL). The average procedure time was 25.1 minutes (range, 18-32 minutes). In one case with a scanty residual hematoma, the catheter was removed at the end of the procedure. In the remaining eight cases, the catheter was left in the residual hematoma for drainage and all catheter tips were accurately located in the final position. There were no procedure-related complications, including rebleeding and infection. CONCLUSION: CTF-guided ICH aspiration is a feasible, quick, and accurate procedure which could substitute for stereotactic methods. The accurate catheter position provided by real-time observation enables an effective aspiration and drainage of hematomas.

ABSTRACT

OBJECTIVE: We evaluated the effect of endovascular treatment (EVT) for acute ischemic stroke in patients over 80 years of age. MATERIALS AND METHODS: The records of 156 acute stroke patients aged over 80 years who were considered as candidates for EVT were analyzed. Fifty-six patients (35.9%, EVT group) underwent EVT and 100 patients (64.1%, non-EVT group) did not. Outcomes, in terms of functional outcomes and rates of symptomatic hemorrhage, in-hospital morbidity and mortality, were compared between groups. Each comparison was adjusted for age, time from onset, initial National Institute of Health Stroke Scale, and pre-stroke modified Rankin Scale (mRS). RESULTS: More patients in the EVT group achieved good outcomes (mRS score of 0-2) at 3 months (35.7% vs. 11.0%, adjusted odds ratio [OR] 4.779 [95% confidence interval 1.972-11.579], p = 0.001) and 12 months (35.7% vs. 14.0%, adjusted OR 3.705 [1.574-8.722], p = 0.003) after stroke. During admission, rates of hospital-acquired infection including pneumonia (12.5% vs. 29.0%, adjusted OR 0.262 [0.098-0.703], p = 0.008) and urinary tract infection (16.0% vs. 34.0%, adjusted OR 0.256 [0.099-0.657], p = 0.005) were significantly lower in the EVT group. More symptomatic hemorrhages (10.7% vs. 2.0%, adjusted OR 6.859 [1.139-41.317], p = 0.036) occurred in the EVT group, but no significant difference was observed in in-hospital mortality rate (12.5% vs. 8.0%, adjusted OR 1.380 [0.408-4.664], p = 0.604). CONCLUSION: EVT improved functional outcome and reduced the risk of hospital-acquired infections in acute stroke patients over 80 years of age without increasing the risk of in-hospital mortality, although symptomatic hemorrhage occurred more frequently after EVT.

ABSTRACT

OBJECTIVE: We evaluated the effect of endovascular treatment (EVT) for acute ischemic stroke in patients over 80 years of age. MATERIALS AND METHODS: The records of 156 acute stroke patients aged over 80 years who were considered as candidates for EVT were analyzed. Fifty-six patients (35.9%, EVT group) underwent EVT and 100 patients (64.1%, non-EVT group) did not. Outcomes, in terms of functional outcomes and rates of symptomatic hemorrhage, in-hospital morbidity and mortality, were compared between groups. Each comparison was adjusted for age, time from onset, initial National Institute of Health Stroke Scale, and pre-stroke modified Rankin Scale (mRS). RESULTS: More patients in the EVT group achieved good outcomes (mRS score of 0-2) at 3 months (35.7% vs. 11.0%, adjusted odds ratio [OR] 4.779 [95% confidence interval 1.972-11.579], p = 0.001) and 12 months (35.7% vs. 14.0%, adjusted OR 3.705 [1.574-8.722], p = 0.003) after stroke. During admission, rates of hospital-acquired infection including pneumonia (12.5% vs. 29.0%, adjusted OR 0.262 [0.098-0.703], p = 0.008) and urinary tract infection (16.0% vs. 34.0%, adjusted OR 0.256 [0.099-0.657], p = 0.005) were significantly lower in the EVT group. More symptomatic hemorrhages (10.7% vs. 2.0%, adjusted OR 6.859 [1.139-41.317], p = 0.036) occurred in the EVT group, but no significant difference was observed in in-hospital mortality rate (12.5% vs. 8.0%, adjusted OR 1.380 [0.408-4.664], p = 0.604). CONCLUSION: EVT improved functional outcome and reduced the risk of hospital-acquired infections in acute stroke patients over 80 years of age without increasing the risk of in-hospital mortality, although symptomatic hemorrhage occurred more frequently after EVT.

ABSTRACT

A ruptured distal lenticulostriate artery (LSA) aneurysm is detected occasionally in moyamoya disease (MMD) patients presented with intracerebral hemorrhage. If the aneurysm is detected in hemorrhage site on angiographic evaluation, its obliteration could be considered, because it rebleeds frequently, and is associated with poorer outcome and mortality in MMD related hemorrhage. In this case report, the authors present two MMD cases with ruptured distal LSA aneurysm treated by endovascular embolization.
