To assess the long-term safety of administering growth hormone (GH) in patients with GH deficiency due to treatment for childhood medulloblastoma and primitive neuroectodermal tumor (PNET). Data were retrospectively retrieved on children receiving GH supplementation, assessing their disease-free and overall survival outcomes and risk of secondary malignancies using Kaplan-Meier and Cox models. Overall 65 children were consecutively collected from May 1981 to April 2013. All patients had undergone craniospinal irradiation (total dose 18-39 Gy), and subsequently received GH for a median (interquartile range, IQR) of 81 (50...

INTRODUCTION: Advanced magnetic resonance imaging (MRI) techniques is an umbrella term that includes diffusion (DWI) and diffusion tensor (DTI), perfusion (PWI), spectroscopy (MRS), and functional (fMRI) imaging. These advanced modalities have improved the imaging of brain tumors and provided valuable additional information for treatment planning. Despite abundant literature on advanced MRI techniques in adult brain tumors, few reports exist for pediatric brain ones, potentially because of technical challenges...

Immunotherapeutic concepts in neurooncology have been developed for many decades but have mainly been hampered by poor definition of relevant antigens and selective measures to target the central nervous system. Independent of the recent remarkable successes in clinical immunooncology with checkpoint inhibitors and vaccines, immunotherapy of brain tumors in general and gliomas in particular has evolved with novel neurooncology-specific concepts over the past years providing new phase 1 approaches of individualized immunotherapy to first phase three clinical trials...

In addition to each of the factors that govern the identification of a successful oncology drug candidate, drug discovery aimed at treating neurological cancer must also consider the presence of the blood-brain barrier (BBB). The high level of expression of efflux transporters (e.g., P-glycoprotein (P-gp) and breast cancer resistance protein (Bcrp)) at the BBB limits many small molecules from freely reaching the brain, where neurooncologic malignancies reside. Furthermore, many of the targets identified for the potential treatment of central nervous system (CNS) malignancies suggest that kinase inhibitors, capable of penetrating the BBB to reach their target, would be desirable...

The surgical resection of cerebral metastases is one key element in a multimodal therapy of brain oligometastatic patients. Standard surgery alone is often not sufficient to achieve local control. Various reasons have been discussed including microscopic and macroscopic tumor rests after surgery and different growth patterns of cerebral metastases: In this review, we assessed the surgical standard technique and then analyzed the growth pattern of cerebral metastases and discussed its oncologic impact and new strategies in the surgical management of cerebral metastases...

BACKGROUND: Optimal treatment and precise classification for anaplastic glioma are needed. METHODS: The objective for long-term follow-up of NOA-04 is to optimize the treatment sequence for patients with anaplastic gliomas. Patients were randomized 2:1:1 to receive the standard radiotherapy (RT) (arm A), procarbazine, lomustine and vincristine (PCV) (arm B1), or temozolomide (TMZ) (arm B2). RESULTS: Primary endpoint was time-to-treatment-failure (TTF), defined as progression after 2 lines of therapy or any time before if no further therapy was administered...

OBJECTIVE: Leptomeningeal metastasis (LM) is a neurooncological complication of advanced cancer that has a poor prognosis. The incidence of LM is increasing due to advances in neuroimaging. At the same time, the development of new systemic treatments with poor central nervous system penetration has improved outcomes and survival. However, diagnosis of LM remains quite difficult due to clinical polymorphism, inconsistent imaging abnormalities, and the inconsistent presence of neoplastic cells in cerebrospinal fluid...

Ceftriaxone-induced immune hemolytic anemia (CIHA) is the second most common cause of drug-induced hemolytic anemia. Prompt recognition of this drug reaction is essential because brisk hemolysis can be deadly. The extent to which ceftriaxone antibodies persist after CIHA is unknown; rechallenging patients who have experienced CIHA is not recommended. We report a case of CIHA in a neurooncology patient, which is the first to show anticeftriaxone antibodies with Rh specificity and persisted for 8 months after the drug reaction...

New treatment modalities in oncology, radiation oncology and surgery have led to a significant improvement in life expectancy for cancer patients. Some will however develop severe neurologic deficits that will impact their quality of life. To limit this impact, it is essential to offer optimal neurorehabilitation. In this context, a pilot project of early and intensive neurorehabilitation for brain tumor patients has been set up. A collaboration between the teams of neurooncology, acute neurorehabilitation and neurosurgery from the CHUV and the Clinique La Lignière allows an intensive and direct neurorehabilitation following neurosurgery...

Glioblastomas are highly aggressive tumors. Their prognosis remain poor despite standard therapies combining surgery, radiation and temozolomide based chemotherapy. Among innovating strategies, there is a major interest for immunotherapy. During the past 3 decades, there has been a general scepticism concerning the efficacy of this approach. But the latest achievements, such as immune checkpoint inhibitors in solid tumors, and adoptive cell therapy in hematologic malignancies, have radically changed the face of the field and have already an impact on the daily practice...

Serum-free culture methods for patient-derived primary glioma cultures, selecting for glioma stem-like cells (GSCs), are becoming the gold standard in neurooncology research. These GSCs can be implemented in drug screens to detect patient-specific responses, potentially bridging the translational gap to personalized medicine. Since numerous compounds are available, a rapid and reliable readout for drug efficacies is required. This can be done using approaches that measure viability, confluency, cytotoxicity, or apoptosis...

Brain radiation is a fundamental tool in neurooncology to improve local tumor control, but it leads to profound and progressive impairments in cognitive function. Increased attention to quality of life in neurooncology has accelerated efforts to understand and ameliorate radiation-induced cognitive sequelae. Such progress has coincided with a new understanding of the role of CNS progenitor cell populations in normal cognition and in their potential utility for the treatment of neurological diseases. The irradiated brain exhibits a host of biochemical and cellular derangements, including loss of endogenous neurogenesis, demyelination, and ablation of endogenous oligodendrocyte progenitor cells...

INTRODUCTION: (11)C-methonine ([(11)C]-MET) positron emission tomography-computed tomography (PET-CT) is a well-established technique for evaluation of tumor for diagnosis and treatment planning in neurooncology. [(11)C]-MET reflects amino acid transport and has been shown to be more sensitive than magnetic resonance imaging (MRI) in stereotactic biopsy planning. This study compared fluorodeoxyglucose (FDG) PET-CT and MET PET-CT in the detection of various brain tumors. MATERIALS AND METHODS: Sixty-four subjects of brain tumor treated by surgery, chemotherapy, and/or radiotherapy were subjected to [(18)F]-FDG, [(11)C]-MET, and MRI scan...

Ependymomas are relatively uncommon gliomas with poor prognosis despite recent advances in neurooncology. Molecular pathogenesis of ependymomas is not extensively studied. Lack of correlation of histological grade with patient outcome has directed attention towards identification of molecular alterations as novel prognostic markers. Recently, 1q gain has emerged as a potential prognostic marker, associated with decreased survival, especially in posterior fossa, high grade tumors. Cases of intracranial ependymomas were retrieved...

Neuroanatomy has entered a new era, culminating in the search for the connectome, otherwise known as the brain's wiring diagram. While this approach has led to landmark discoveries in neuroscience, potential neurosurgical applications and collaborations have been lagging. In this article, the authors describe the ideas and concepts behind the connectome and its analysis with graph theory. Following this they then describe how to form a connectome using resting state functional MRI data as an example. Next they highlight selected insights into healthy brain function that have been derived from connectome analysis and illustrate how studies into normal development, cognitive function, and the effects of synthetic lesioning can be relevant to neurosurgery...
