RESUMEN
The management of meningioma in elderly patients (MEP) presents a complex and evolving challenge. Data available offer conflicting information on treatment options and complications. This survey aimed to examine the current approach to MEP, comparing the national profile to data in the current literature. A survey addressing the treatments options and management of meningioma in elderly was designed on behalf of SINch® (Società Italiana di Neurochirurgia) and sent via email to all Chiefs of Neurosurgical Departments. The survey remained open for responses from May 5th, 2022, until November 21st, 2022. A search of the literature published between January 2000 and March 2023, in accordance to PRISMA guidelines, was included. A total of 51 Neurosurgical centers participated in the survey. The caseload profile of each center influences the choice of treatment selection (Stereotactic Radiosurgery versus open surgery) (p = 0.01) and the consolidated practice of discussing cases within a multidisciplinary group (p = 0.02). The pooled meta-analysis demonstrated a significant increased risk in the elderly group for permanent deficits (p < 0.00001), postoperative infections (p = 0.0004) and hemorrhage (p = 0.0001), perioperative mortality (p < 0.00001), and medical complications (p < 0.00001) as compared to the young population. This study presents the initial comprehensive analysis of the existing trends in the surgical management of MEP in Italy. The significant variation in practices primarily stems from the absence of standardized guidelines. While most centers have adopted an integrated approach, there is a need to promote a multidisciplinary care model. Prospective studies are needed to gather robust evidence in this clinical setting.

OBJECTIVE: Surgery is the mainstay of treatment for low-grade glioma (LGG)-related epilepsy. However, the goal of achieving both oncological radical resection and seizure freedom can be challenging. PET with [11C]methionine (MET) has been recently introduced in clinical practice for the management of patients with LGGs, not only to monitor the response to treatments, but also as a preoperative tool to define the metabolic tumor extent and to predict tumor grading, type, and prognosis. Still, its role in defining tumor-related epilepsy and postoperative seizure outcomes is limited. The aim of this preliminary study was to investigate the role of MET PET in defining preoperative seizure characteristics and short-term postoperative seizure control in a cohort of patients with newly diagnosed temporal lobe low-grade gliomas (tLGGs). METHODS: Patients with newly diagnosed and histologically proven temporal lobe grade 2/3 gliomas (2021 WHO CNS tumor classification) who underwent resection at the authors' institution between July 2011 and March 2021 were included in this retrospective study. MET PET images were acquired, fused with MRI scans, and qualitatively and semiquantitatively analyzed. Any eventual PET/MRI involvement of the temporomesial area, seizure characteristics, and 1-year seizure outcomes were reported. RESULTS: A total of 52 patients with tLGGs met the inclusion criteria. MET PET was positive in 41 (79%) patients, with a median metabolic tumor volume of 14.56 cm3 (interquartile range [IQR] 6.5-28.2 cm3). The median maximum and mean tumor-to-background ratio (TBRmax, TBRmean) were 2.24 (IQR 1.58-2.86) and 1.53 (IQR 1.37-1.70), respectively. The metabolic tumor volume was found to be related to the presence of seizures at disease onset, but only in noncodeleted tumors (p = 0.014). Regarding patients with uncontrolled seizures at surgery, only the temporomesial area PET involvement showed a statistical correlation both in the univariate (p = 0.058) and in the multivariate analysis (p = 0.030). At 1-year follow-up, seizure control was correlated with MET PET-derived semiquantitative data. Particularly, higher TBRmax (p = 0.0192) and TBRmean (p = 0.0128) values were statistically related to uncontrolled seizures 1 year after surgery. CONCLUSIONS: This preliminary study suggests that MET PET may be used as a preoperative tool to define seizure characteristics and outcomes in patients with tLGGs. These findings need to be further validated in larger series with longer epileptological follow-ups.

BACKGROUND: Petroclival meningiomas are challenging tumors. Several skull base approaches have been proposed in the last decades, with variable rates of postoperative morbidity and extent of resection. METHODS: We herein reported the step-by-step microsurgical resection of a large petroclival meningioma through an extended retrosigmoid approach. Detailed surgical technique has been accompanied by a 2D operative video. CONCLUSION: The extended retrosigmoid approach allowed for a safe gross total resection of the tumor, as confirmed by the postoperative MRI. The patient did not experience any new postoperative deficit, despite a transient diplopia, and was discharged on postoperative day 7.

PURPOSE: Gamma Knife radiosurgery (GKRS) has emerged as an effective treatment option for trigeminal neuralgia (TN) in patients with multiple sclerosis (MS). To date, the outcomes of repeat GKRS for patients with TN and MS with recurrent pain have been investigated in a few patients. This study aims to report the outcomes and predictive factors of pain reduction for MS patients undergoing repeat GKRS for recurrent TN. METHODS: Eighteen patients with MS underwent repeat GKRS for recurrent TN. A retrospective chart review and telephone interviews were conducted to determine background medical history, dosimetric data, and outcomes of the procedure. Facial pain and sensory function were evaluated using the Barrow Neurological Institute (BNI) scales. RESULTS: Fifteen patients achieved a BNI pain score of IIIa or better, indicating pain reduction, within a median period of 21 days after repeat GKRS. The maximum dose for repeat GKRS ranged from 70 to 85 Gy. Pain recurred in 5 patients after a median period of 12 months after GKRS. Percentages of patients with pain reduction at 1, 2, 3, 5, and 7 years were 60%, 60%, 50%, 50%, and 50%, respectively. Older age at repeat GKRS predicted sustained pain reduction (P = 0.01). Seven patients developed facial sensory disturbances, which were bothersome in two patients. CONCLUSIONS: Repeat GKRS may be used as an effective treatment modality for prolonging the duration of pain reduction time in patients with MS and TN. After repeat GKRS, facial sensory disturbances are common; however, they are often not bothersome.

BACKGROUND: The prognostic value of the extent of resection in the management of Glioblastoma is a long-debated topic, recently widened by the 2022 RANO-Resect Classification, which advocates for the resection of the non-enhancing disease surrounding the main core of tumors (supramaximal resection, SUPR) to achieve additional survival benefits. We conducted a retrospective analysis to corroborate the role of SUPR by the RANO-Resect Classification in a single center, homogenous cohort of patients. METHODS: Records of patients operated for WHO-2021 Glioblastomas at our institution between 2007 and 2018 were retrospectively reviewed; volumetric data of resected lesions were computed and classified by RANO-Resect criteria. Survival and correlation analyses were conducted excluding patients below near-total resection. RESULTS: 117 patients met the inclusion criteria, encompassing 45 near-total resections (NTR), 31 complete resections (CR), and 41 SUPR. Median progression-free and overall survival were 11 and 15 months for NTR, 13 and 17 months or CR, 20 and 24 months for SUPR, respectively (p < 0.001), with inverse correlation observed between survival and FLAIR residual volume (r -0.28). SUPR was not significantly associated with larger preoperative volumes or higher rates of postoperative deficits, although it was less associated with preoperative neurological deficits (OR 3.37, p = 0.003). The impact of SUPR on OS varied between MGMT unmethylated (HR 0.606, p = 0.044) and methylated (HR 0.273, p = 0.002) patient groups. CONCLUSIONS: Results of the present study support the validity of supramaximal resection by the new RANO-Resect classification, also highlighting a possible surgical difference between tumors with methylated and unmethylated MGMT promoter.

PURPOSE: The management of brain tumors during pregnancy is challenging. The clinical rarity and prognostic heterogeneity of such condition makes it difficult to develop standardized guidelines of treatment. The aim of this study was to assess the treatment options used in pregnant women with brain tumors that are currently used in Italy, considering the management of these patients reported in current literature in this field. METHODS: A survey addressing the treatments options and management of brain tumors during pregnancy was designed on behalf of an ad-hoc task-force Neuro-Oncology committee of the Società Italiana di Neurochirurgia (SINch) to analyze the management of pregnant patients with brain tumors. We conducted a search of the literature published between January 2011 and September 2021, using MEDLINE (PubMed) in accordance to PRISMA guidelines. Data were discussed to obtain recommendations after evaluation of the selected articles and discussion among the experts. RESULTS: A total of 18 Neurosurgical centers participated in the survey. A total of 31 pregnant women were included in this retrospective study. Meningiomas and gliomas were the two most common types of brain tumors diagnosed during pregnancy. An emergency surgical procedure was required in 12.9% of cases. CONCLUSION: A multidisciplinary and tailored approach is fundamental. In women showing clinical stability, neurosurgical options should preferably be delayed if possible, and considered during the second trimester or after delivery. In patients with acute neurological symptoms or tumor progression, medical abortion in the first trimester or a C-section in the second and third trimester need to be considered.

PURPOSE: IDH-wildtype (IDH-wt) diffuse gliomas with histological features of lower-grade gliomas (LGGs) are rare and heterogeneous primary brain tumours. [11C]Methionine (MET) positron emission tomography (PET) is commonly used to evaluate glial neoplasms at diagnosis. The present study aimed to assess the prognostic value of MET PET in newly diagnosed, treatment naïve IDH-wt gliomas with histological features of LGGs. METHODS: Patients with a histological diagnosis of IDH-wt LGG who underwent preoperative (< 100 days) MET PET/CT and surgery were retrospectively included. Qualitative and semi-quantitative analyses of MET PET images were performed. Progression-free survival (PFS) and overall survival (OS) were analysed by Kaplan-Meier curves. Cox proportional-hazards regression was used to test the association of imaging and clinical data to PFS and OS. RESULTS: We included 48 patients (M:F = 25:23; median age 55). 39 lesions were positive and 9 negative at MET PET. Positive MET PET was significantly associated with shorter median PFS (15.7 months vs. not reached, p = 0.0146) and OS time (32.6 months vs. not reached, p = 0.0253). Incomplete surgical resection and higher TBRmean values were independent predictors of shorter PFS on multivariate analysis (p < 0.001 for both). Higher tumour grade and incomplete surgical resection were independent predictors of OS at multivariate analysis (p = 0.027 and p = 0.01, respectively). CONCLUSION: MET PET is useful for the prognostic stratification of patients with IDH-wt glial neoplasms with histological LGGs features. Considering their huge biological heterogeneity, the combination of MET PET and molecular analyses may help to improve the prognostic accuracy in these diffuse gliomas subset and influence therapeutic choices accordingly.
RESUMEN
PURPOSE: The extent of resection (EOR) is an independent prognostic factor for overall survival (OS) in adult patients with Glioma Grade 4 (GG4). The aim of the neuro-oncology section of the Italian Society of Neurosurgery (SINch®) was to provide a general overview of the current trends and technical tools to reach this goal. METHODS: A systematic review was performed. The results were divided and ordered, by an expert team of surgeons, to assess the Class of Evidence (CE) and Strength of Recommendation (SR) of perioperative drugs management, imaging, surgery, intraoperative imaging, estimation of EOR, surgery at tumor progression and surgery in elderly patients. RESULTS: A total of 352 studies were identified, including 299 retrospective studies and 53 reviews/meta-analysis. The use of Dexamethasone and the avoidance of prophylaxis with anti-seizure medications reached a CE I and SR A. A preoperative imaging standard protocol was defined with CE II and SR B and usefulness of an early postoperative MRI, with CE II and SR B. The EOR was defined the strongest independent risk factor for both OS and tumor recurrence with CE II and SR B. For intraoperative imaging only the use of 5-ALA reached a CE II and SR B. The estimation of EOR was established to be fundamental in planning postoperative adjuvant treatments with CE II and SR B and the stereotactic image-guided brain biopsy to be the procedure of choice when an extensive surgical resection is not feasible (CE II and SR B). CONCLUSIONS: A growing number of evidences evidence support the role of maximal safe resection as primary OS predictor in GG4 patients. The ongoing development of intraoperative techniques for a precise real-time identification of peritumoral functional pathways enables surgeons to maximize EOR minimizing the post-operative morbidity.

BACKGROUND: The treatment of medically refractory patients with chronic short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is challenging. Stereotactic radiosurgery targeting the trigeminal nerve and sphenopalatine ganglion (SPG) has been used as a less-invasive treatment. The outcomes of this procedure have been described in a few case reports. OBJECTIVES: The objective of the study was to report on the effect of Gamma Knife radiosurgery (GKRS) in 5 patients with chronic SUNCT. METHODS: Retrospective review of our GKRS database identified 5 patients with chronic SUNCT who underwent GKRS targeted to the trigeminal nerve and SPG. A maximum dose of 80-85 Gy and 80 Gy was, respectively, delivered to the trigeminal nerve and SPG. Pain intensity and facial numbness were evaluated using the Barrow Neurological Institute (BNI) scores. RESULTS: These 5 patients were clinically followed for a mean period of 26.2 months. Within a period ranging from 2 days to 9 months, GKRS was successful in reducing pain attacks and autonomic symptoms in all 5 patients. At the last assessments, BNI pain scores of I, II, and IIIa were achieved in 1, 1, and 3 patients, respectively. Two patients developed nonbothersome facial numbness (BNI facial numbness score II). CONCLUSIONS: These 5 cases show that GKRS targeted to both the trigeminal nerve and the SPG is effective in reducing pain and autonomic symptoms of patients with SUNCT, although nonbothersome trigeminal sensory disturbances may occur.

BACKGROUND: Rosette-forming glioneuronal tumor (RGNT) is a rare slow-growing neoplasm with mixed glial and neurocytic components. Surgical resection is the mainstay of treatment, whereas the role of adjuvant radiation therapies for residual or recurrent tumors has been poorly investigated. CASE PRESENTATION: We describe the case of a patient with a recurrent fourth ventricular RGNT who was treated with two-staged Gamma Knife radiosurgery (GKRS). GKRS was effective in controlling tumor growth and safe up to seven years from treatment. CONCLUSIONS: This case suggests that GKRS may be a safe and effective treatment for patients with recurrent or residual RGNT.

BACKGROUND: Ependymomas are glial cell tumors whose recommended treatment, according to the recent European guidelines, is surgical. Patient outcomes, in terms of progression-free survival and overall survival, are strongly related to the extent of resection. However, in some cases, critical locations and/or large dimensions could make a gross total resection challenging. In this article, we describe the surgical anatomy and technique of a combined telovelar-posterolateral approach for the resection of a giant posterior fossa ependymoma. METHODS: A 24-year-old patient who presented to our institution complaining of a 3-month history of headache, vertigo, and imbalance. Preoperative MRI scans showed a large mass within the fourth ventricle, extending towards the left cerebellopontine angle and perimedullary space through the homolateral Luschka foramen. Surgical treatment was proposed with the aims of releasing the preoperative symptoms, obtaining the tumor's histopathological and molecular definition, and preventing any future neurological deterioration. The patient gave his written consent for surgery and consented to the publication of his images. A combined telovelar-posterolateral approach was then performed to maximize the tumor's exposure and resection. Surgical technique and anatomical exposure have been extensively described, and a 2-dimensional operative video has been included. RESULTS: The postoperative MRI scan demonstrated an almost complete resection of the lesion, with only a millimetric tumor remnant infiltrating the uppermost portion of the inferior medullary velum. Histo-molecular analysis revealed a grade 2 ependymoma. The patient was discharged home neurologically intact. CONCLUSIONS: The combined telovelar-posterolateral approach allowed to achieve a near total resection of a giant multicompartimental mass within the posterior fossa in a single surgical stage.

BACKGROUND: Surgical treatment of dumbbell jugular foramen schwannomas can be challenging. The main goals of surgery are maximal resection with preservation of function and overall patient quality of life. METHODS: In this paper, we present a step-by-step technical description of a microsurgical resection of dumbbell-shaped JF schwannoma using a modified retrosigmoid infra-jugular approach. CONCLUSION: The modified retrosigmoid infra-jugular is a safe and suitable approach in selected cases. This technique, however, must be limited only to those tumors with minimal extension into the jugular foramen.

Medial thalamotomy using stereotactic radiosurgery (SRS) is a potential treatment for intractable pain. However, the ideal treatment parameters and expected outcomes from this procedure remain unclear. The aim of this systematic review is to provide further insights on medial thalamotomy using SRS, specifically for intractable pain. A systematic review was performed to identify all clinical articles discussing medial thalamotomy using SRS for intractable pain. Only studies in which SRS was used to target the medial thalamus for pain were included. For centers with multiple publications, care was taken to avoid recounting individual patients. The literature review revealed six studies describing outcomes of medial thalamotomy using SRS for a total of 125 patients (118 included in the outcome analysis). Fifty-two patients were treated for cancer pain across three studies, whereas five studies included 73 patients who were treated for nonmalignant pain. The individual studies demonstrated initial meaningful pain reduction in 43.3-100% of patients, with an aggregate initial meaningful pain reduction in 65 patients (55%) following SRS medial thalamotomy. This effect persisted in 45 patients (38%) at the last follow-up. Adverse events were observed in six patients (5%), which were related to radiation in five patients (4%). Medial thalamotomy using SRS is effective for select patients with treatment-resistant pain and is remarkably safe when modern radiation delivery platforms are used. More posteriorly placed lesions within the medial thalamus were associated with better pain relief. More studies are warranted to shed light on differences in patient responses.

During the Greco-Italian War (World War II [WWII], 1940-1941), an Italian field hospital was set up in Sinanaj, Albania. The hospital's military surgeons carefully collected information about the characteristics and management of patients with war-related injuries. In 1942, they published a detailed report, with a section dedicated to the management of war-related head injuries. The aim of this report is to analyze that section, to describe the characteristics and neurosurgical management of war-related head injuries, and to depict the status of war neurosurgery in the Royal Italian Army during WWII. The analysis revealed that, during the Greco-Italian War (November 1940-April 1941), 149 patients with war-related head injuries were admitted to the Sinanaj hospital, and 48 patients underwent surgery. Head injuries were caused by bomb fragments in 126 patients, bullets in 5 patients, and other causes (falls from height, vehicle accidents, or rock fragments) in 18 patients. Six patients (12.5%) died after surgery. Before surgery, patients underwent resuscitation with blood transfusions and fluid. Preoperatively, a plain head radiograph was usually acquired to locate metallic and bone fragments. The surgical technique consisted of craniotomy or craniectomy, aggressive debridement of metallic and bone fragments, and watertight dural closure. Surgical drainage, overall aseptic technique, serial spinal taps, and perioperative antibiotics were used to prevent infections. The surgical aims and technique used by the Italian surgeons for the management of head injuries were similar to those of the Allied surgeons during WWII. Operative mortality was also comparable. Although the surgical technique for war-related head injuries has evolved since WWII, many aspects of the technique used by the Italian and Allied surgeons during WWII are still in the standard of care today.

ABSTRACT: Spheno-orbital meningiomas (SOM) are slow growing tumors that often cause proptosis and visual deficits, due to direct compression of adjacent structures or hyperostosis of surrounding bones.Traditionally, these lesions are approached via a lateral transcranial route. Recent interest in mini-invasive surgery and endoscopy brought many authors to study different trans-nasal or transorbital approaches.The authors report a surgical case series with 3 patients with proptosis due to SOM who underwent surgery in our institution via an inferolateral trans-orbital endoscopic approach. The authors described our surgical technique and the authorsretrospectively reviewed the clinical and radiological outcomes of the patients.All 3 patients had an effective orbital decompression with improvement of the proptosis and pain relief. Histological examination was possible and no intraoperative nor postoperative complications were observed.Therefore, the authors consider inferolateral trans-orbital endoscopic approach as a feasible approach for lesions involving the lateral orbit compartment arising from middle cranial fossa or from orbit itself.

OBJECTIVES: Temporal muscle thickness (TMT) is a surrogate marker of sarcopenia, correlated with survival expectancy in patients suffering from brain metastases and recurrent or treated glioblastoma. We evaluated the prognostic relevance of TMT measured on brain MRIs acquired at diagnosis in patients affected by glioblastoma. METHODS: We retrospectively enrolled 51 patients in our Institution affected by methylated MGMT promoter, IDH1-2 wild-type glioblastoma, who underwent complete surgical resection and subsequent radiotherapy with concomitant and maintenance temozolomide, from January 1, 2015, to April 30, 2017. The last clinical/radiological follow-up date was set to September 3, 2019. TMT was measured bilaterally on reformatted post-contrast 3D MPRAGE images, acquired on our 3-T scanner no more than 2 days before surgery. The median, 25th, and 75th percentile TMT values were identified and population was subdivided accordingly; afterwards, statistical analyses were performed to verify the association among overall survival (OS) and TMT, sex, age, and ECOG performance status. RESULTS: In our cohort, the median OS was 20 months (range 3-51). Patients with a TMT ≥ 8.4 mm (median value) did not show a statistically significant increase in OS (Cox regression model: HR 1.34, 95% CI 0.68-2.63, p = 0.403). Similarly, patients with a TMT ≥ 9.85 mm (fourth quartile) did not differ in OS compared to those with TMT ≤ 7 mm (first quartile). The statistical analyses confirmed a significant association among TMT and sex (p = 0.0186), but none for age (p = 0.642) and performance status (p = 0.3982). CONCLUSIONS: In our homogeneous cohort of patients with glioblastoma at diagnosis, TMT was not associated with prognosis, age, or ECOG performance status. KEY POINTS: ⢠Temporal muscle thickness (TMT) is a surrogate marker of sarcopenia and has been correlated with survival expectancy in patients suffering from brain metastases and recurrent or treated glioblastoma. ⢠We appraised the correlation among TMT and survival, sex, age at surgery, and performance status, measured on brain MRIs of patients affected by glioblastoma at diagnosis. ⢠TMT did not show any significant correlation with prognosis, age at surgery, or performance status, and its usefulness might be restricted only to patients with brain metastases and recurrent or treated glioblastoma.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) has changed the way in which cancer is treated. Patients with high-grade glioma (HGG) are believed to be in a vulnerable category. The aim of this study was to describe the experience of a hub cancer center and the measures that were put in place for treatment of patients with newly diagnosed and recurrent glioma. METHODS: To prevent in-hospital contagion and preserve the safety of health professionals and patients, specific protocols and strict regulations were introduced. Physical distancing, use of surgical masks, and diligent hand hygiene were adopted. Each case was discussed in a multidisciplinary board meeting before treatment. All patient candidates for surgical procedures were tested for SARS-CoV-2 with a nasopharyngeal swab and a chest CT scan. Indications for surgery were the radiological suspicion of HGG in patients with a good performance status and/or the rapid and progressive occurrence of neurological deficits. Adjuvant treatments were performed only in cases of HGG. This therapy consisted of conventional fractional radiotherapy (RT; 60 Gy/30 fractions) with concomitant and adjuvant temozolomide chemotherapy (TMZCHT) in younger patients; in elderly patients, a short course of RT was employed (40.5 Gy/15 fractions). For recurrent HGG, treatments were assessed after a careful evaluation of the patient's general condition, neurological status, and risk of early impairment in neurological status if not treated. During simulation CT for the RT plan, each patient underwent a chest CT study. In cases in which an imaging study was suspicious for COVID-19 pneumonia, the patient was immediately isolated and rapidly underwent nasopharyngeal swab testing. RESULTS: Between March 1 and April 30, 2020, 23 HGGs were treated, and these cases are included in the present evaluation. Fifteen patients harboring newly diagnosed glioblastoma (GBM) underwent resection followed by a regimen of chemotherapy and RT, and 3 patients with newly diagnosed anaplastic oligodendroglioma underwent surgery followed by adjuvant RT. Five patients were treated for recurrent GBM, and they received surgery plus adjuvant RT. One patient in whom the simulation CT study was suspicious for COVID pneumonia was tested with a nasopharyngeal swab, which proved positive for SARS-CoV-2 infection. No patients contracted COVID-19 during hospitalization for surgery or during RT treatment. Corticosteroid therapy was administered to all patients beginning on the 1st day of RT. CONCLUSIONS: The authors' experience during the COVID-19 pandemic showed that patients with HGG can be treated in the most effective manner without a compromise in safety. Careful selection criteria and a multidisciplinary evaluation are pivotal to assessing the optimal therapeutic strategy.

BACKGROUND: Stereotactic biopsy is consistently employed to characterize cerebral lesions in patients who are not suitable for microsurgical resection. In the past years, technical improvement and neuroimaging advancements contributed to increase the diagnostic yield, the safety, and the application of this procedure. Currently, in addition to histological diagnosis, the molecular analysis is considered essential in the diagnostic process to properly select therapeutic and prognostic algorithms in a personalized approach. The present study reports our experience with frameless stereotactic brain biopsy in this molecular era. METHODS: One hundred forty consecutive patients treated from January 2013 to September 2018 were analyzed. Biopsies were performed using the Brainlab Varioguide® frameless stereotactic system. Patients' clinical and demographic data, the time of occupation of the operating room, the surgical time, the morbidity, and the diagnostic yield in providing a histological and molecular diagnosis were recorded and evaluated. RESULTS: The overall diagnostic yield was 93.6% with nine procedures resulting non-diagnostic. Among 110 patients with glioma, the IDH-1 mutational status was characterized in 108 cases (98.2%), resulting wild-type in all subjects but 3; MGMT methylation was characterized in 96 cases (87.3%), resulting present in 60 patients, and 1p/19q codeletion was founded in 6 of the 20 cases of grade II-III gliomas analyzed. All the specimens were apt for molecular analysis when performed. Bleeding requiring surgical drainage occurred in 2.1% of the cases; 8 (5.7%) asymptomatic hemorrhages requiring no treatment were observed. No biopsy-related mortality was recorded. Median length of hospital stay was 5 days (IQR 4-8) with mean surgical time of 60.77 min (± 23.12) and 137.44 ± 24.1 min of total occupation time of the operative room. CONCLUSIONS: Stereotactic frameless biopsy is a safe, feasible, and fast procedure to obtain a histological and molecular diagnosis.

Purpose The primary aim of this prospective observational study was to assess whether diffusion MRI metrics correlate with isocitrate dehydrogenase (IDH) status in grade II and III gliomas. A secondary aim was to investigate whether multishell acquisitions with advanced models such as neurite orientation dispersion and density imaging (NODDI) and diffusion kurtosis imaging offer greater diagnostic accuracy than diffusion-tensor imaging (DTI). Materials and Methods Diffusion MRI (b = 700 and 2000 sec/mm2) was performed preoperatively in 192 consecutive participants (113 male and 79 female participants; mean age, 46.18 years; age range, 14-77 years) with grade II (n = 62), grade III (n = 58), or grade IV (n = 72) gliomas. DTI, diffusion kurtosis imaging, and NODDI metrics were measured in regions with or without hyperintensity on diffusion MR images and compared among groups defined according to IDH genotype, 1p/19q codeletion status, and tumor grade by using Mann-Whitney tests. Results In grade II and III IDH wild-type gliomas, the maximum fractional anisotropy, kurtosis anisotropy, and restriction fraction were significantly higher and the minimum mean diffusivity was significantly lower than in IDH-mutant gliomas (P = .011, P = .002, P = .044, and P = .027, respectively); areas under the receiver operating characteristic curve ranged from 0.72 to 0.76. In IDH wild-type gliomas, no difference among grades II, III, and IV was found. In IDH-mutant gliomas, no difference between those with and those without 1p/19q loss was found. Conclusion Diffusion MRI metrics showed correlation with isocitrate dehydrogenase status in grade II and III gliomas. Advanced diffusion MRI models did not add diagnostic accuracy, supporting the inclusion of a single-shell diffusion-tensor imaging acquisition in brain tumor imaging protocols.

ASTRACT: BACKGROUND: The incidence of glioblastoma among elderly patients is constantly increasing. The value of radiation therapy and concurrent/adjuvant chemotherapy has been widely assessed. So far, the role of surgery has not been thoroughly investigated. The study aimed to evaluate safety and impact of several entities of surgical resection on outcome of elderly patients with newly diagnosed glioblastoma treated by a multimodal approach. METHODS: Patients ≥ 65 years, underwent surgery were included. The extent of surgical resection (EOR) was defined as complete resection (CR = 100%), gross total resection (GTR = 90-99%), sub-total resection (STR = 78-90%), partial resection (PR = 30-78%), and biopsy. After surgery, all patients received adjuvant radiotherapy (60/2 Gy fraction) with concomitant/adjuvant temozolomide chemotherapy. RESULTS: From March 2004 to December 2015, 178 elderly with a median age of 71 years (range 65-83 years) were treated. CR was obtained in 8 (4.5%), GTR in 63 (35.4%), STR in 46 (25.8%), PR in 16 (9.0%), and biopsy in 45 (25.3%). RT was started in all patients, concurrent/adjuvant CHT in 149 (83.7%) and 132 (74.2%). The median follow-up time was 12.2 months (range 0.4-50.4 months). The median, 1- and 2-year progression-free survival was 8.9 months (95%CI 7.8-100 months), 32.0 ± 3.5%, and 12.9 ± 2.6%. The median, 1- and 2-year overall survival were 12.2 (95%CI 11.3-13.1 months), 51.1 ± 3.7%, and 16.3 ± 2.9%. Tumor location, extent of resection, and neurological status after surgery statistically affected survival (p ⪠0.01). CONCLUSION: Maximal surgical resection is safe and feasible in elderly patients with influence on survival. A preoperative evaluation has to be carried out.
