Cerebellar glioblastoma in adults: a comparative single-center matched pair analysis and systematic review of the literature.

Purpose: The rarity of cerebellar glioblastoma presents a significant challenge in clinical practice due to the lack of extensive prognostic data on long-term survival rates, rendering it an underrepresented entity compared to its supratentorial counterpart. This study aims to analyze potential differences in survival outcome between patients with cerebellar and supratentorial glioblastomas.

Methods: From 2009 to 2020, 8 patients underwent surgical treatment for cerebellar glioblastoma at the authors' institution.

Enhancing targeted therapy by combining PI3K and AKT inhibitors with or without cisplatin or vincristine in medulloblastoma cell lines in vitro.

Aim: Despite current intensive therapy, survival rates of medulloblastoma (MB) greatly vary according to molecular subgroup, so new therapies are needed. Recently, we showed that combining phosphoinositide 3-kinase (PI3K), fibroblast growth factor receptor and cyclin-dependent-kinase-4/6 inhibitors (BYL719, JNJ-42756493 and PD-0332991, respectively) or poly (ADP-ribose) polymerase (PARP) and WEE-1 inhibitors (BMN673 and MK1775 respectively) had synergistic effects on MB. Here, in continuation, we investigated the effects of single and combined administrations of PI3K and AKT inhibitors, with/without cisplatin or vincristine on adherent or suspension cultures of different MB subgroups as well as in a spheroid culture of one MB line.

Central Hearing Loss in a Pediatric Patient.

Sensorineural hearing loss is typically caused by dysfunction of the inner ear or auditory nerve. In pediatric patients diagnosed with sensorineural hearing loss, work-up often includes genetic testing and imaging studies of the auditory pathway. Here, we report a case of a pediatric patient with a history of sensorineural hearing loss following cisplatin and radiation therapy for brainstem medulloblastoma, developing symptoms and signs of central hearing loss based on audiometric and MRI/diffusion tensor imaging studies.

The Pediatric Physiatric Posterior Fossa Symptoms scale (3PFSs): Impairments and outcome in pediatric inpatient rehabilitation for posterior fossa brain tumors.

Background: Clinical recognition of the post-operative neurologic sequelae of posterior fossa tumors is inconsistent. This study aimed to characterize functional impairments and recovery trajectories in pediatric patients admitted to inpatient rehabilitation following surgical resection of posterior fossa brain tumors. This study also introduces the Pediatric Physiatric Posterior Fossa Symptom scale (3PFSs) for serial assessment of post-operative symptoms in pediatric posterior fossa brain tumors.

Combination treatment with histone deacetylase and carbonic anhydrase 9 inhibitors shows therapeutic potential in experimental diffuse intrinsic pontine glioma.

Diffuse intrinsic pontine glioma (DIPG) remains a significant therapeutic challenge due to the lack of effective and safe treatment options. This study explores the potential of combining histone deacetylase (HDAC) and carbonic anhydrase 9 (CA9) inhibitors in treating DIPG. Analysis of RNA sequencing data and tumor tissue from patient samples for the expression of the carbonic anhydrase family and hypoxia signaling pathway activity revealed clinical relevance for targeting CA9 in DIPG.

Clinical, Histologic, and Therapeutic Pattern of Posterior Fossa Tumors in Children in Cameroon: A Cross-sectional Study.

Introduction: Posterior fossa tumors are significant in pediatric neurooncological populations due to their frequency and morbimortality. We convey a 10-year experience managing pediatric posterior fossa tumors at two reference centers in Cameroon.

Materials And Methods: We conducted a cross-sectional study with data collected retrospectively in the Neurosurgery Department of the Central and General Hospitals of Yaounde from January 2010 to December 2019.

Pediatric Brainstem Tumor Biopsy: Surgical Planning and Execution for Maximal Safety and Tissue Yield.

Brainstem tumors account for 10-20% of pediatric brain tumors with a peak age of diagnosis between 7 and 9 years old and are often fatal. Historically, diagnosis of brainstem tumors has been largely based on imaging; however, recent studies have demonstrated the incongruities between preoperative MRI diagnosis and postoperative pathological findings highlighting the importance of brainstem biopsy for diagnostic accuracy. Stereotactic brainstem biopsy for pediatric brainstem tumors has been proven to be safe with a high diagnostic yield (96.

Geometric target margin strategy of proton craniospinal irradiation for pediatric medulloblastoma.

In proton craniospinal irradiation (CSI) for skeletally immature pediatric patients, a treatment plan should be developed to ensure that the dose is uniformly delivered to all vertebrae, considering the effects on bone growth balance. The technical (t) clinical target volume (CTV) is conventionally set by manually expanding the CTV from the entire intracranial space and thecal sac, based on the physician's experience. However, there are differences in contouring methods among physicians.

Consensus guidelines for the management of brain stem and diffuse midline glioma for low- and middle-income countries.

The understanding of brainstem gliomas and diffuse midline gliomas has significantly increased in the last decade. However, the management paradigm remains a dilemma. The critical location is the foremost factor dictating the outcome.

Consensus guidelines for the management of pediatric medulloblastoma in low and middle-income countries.

The management of medulloblastoma, a pediatric brain tumor, has evolved significantly with the advent of genomic subgrouping, yet morbidity and mortality remain high in LMICs like Pakistan due to inadequate multidisciplinary care infrastructure. This paper aims to establish evidence-based guidelines tailored to the constraints of such countries. An expert panel comprising neuro-oncologists, neurosurgeons, radiologists, radiation oncologists, neuropathologists, and pediatricians collaborated to develop these guidelines, considering the specific challenges of pediatric brain tumor care in Pakistan.

Tenovin-6 exhibits inhibitory effects on the growth of Sonic Hedgehog (SHH) medulloblastoma, as evidenced by both in vitro and in vivo studies.

Medulloblastoma (MB) is the most common malignant brain tumor in children. Within MB, tumors driven by the Sonic Hedgehog (SHH) pathway represent the most heterogeneous subtype, known as SHH subtype medulloblastoma (SHH-MB). Tenovin-6, a recognized p53 activator, has been demonstrated to inhibit autophagy and modulate sirtuin activity, underscoring its potential as a novel therapeutic agent across various malignancies.

Invasive trigeminal ganglioneuroma: A case report and review of the literature.

Ganglioneuromas are rare tumors arising from retroperitoneal and posterior mediastinal sympathetic nerves. Intracranial trigeminal nerve ganglioneuromas are even more rare, with only seven cases reported to date. We present a case of a 65-year-old male with a right-sided throbbing headache type and blindness in his right eye.

Epigenetic reprogramming enables NF1A/B oncogenic role in SHH medulloblastoma.

In this issue of Developmental Cell, Shiraishi et al. investigate the epigenetic changes occurring during the formation of SHH medulloblastoma and show that an epigenomic shift renders Nuclear Factor I family of transcription factors oncogenic.

Proteomic profiling of cerebrospinal fluid reveals TKT as a potential biomarker for medulloblastoma.

Cerebrospinal fluid (CSF) plays an important role in brain tumors, including medulloblastoma (MBL). Recent advancements in mass spectrometry systems and 'Omics' data analysis methods enable unbiased, high proteome depth research. We conducted proteomic profiling of the total CSF in MBL patients with the purpose of finding a potential diagnostic biomarker for MBL.
