OBJECTIVE: To understand why some adults with primary brain tumors do not use support services despite indications of a need for help. METHODS: Nineteen adults recently diagnosed with primary brain tumors participated in semi-structured interviews. Thematic analysis was used to identify recurrent ways participants explained their non-use of support services. RESULTS: Some patients indicated that they did not use support services as they did not need help, in particular reporting positive experiences relative to their expectations or to others, that their needs were met, or difficulties recognizing their needs...

Surgery after administering bevacizumab should be carefully considered particularly because of wound healing concerns. A 27-year-old man presented with multiple tumor recurrences after gross total removal of a left temporal oligodendroglioma (1p/19q-noncodeleted). Whole brain radiotherapy with concomitant temozolomide and bevacizumab was immediately prescribed; however, the patient's condition deteriorated because of brain herniation. Three days after administering bevacizumab, an emergency tumor removal with external decompression and a ventriculo-peritoneal shunt was performed...

Malignant glioma is one of the most challenging central nervous system diseases to treat, and has high rates of recurrence and mortality. The current therapies include surgery, radiation therapy, and chemotherapy, although these approaches often failed to control tumor progression or improve patient survival. Sonodynamic therapy is a developing cancer treatment that uses ultrasound combined with a sonosensitizer to synergistically kill tumor cells, and has provided impressive results in both in vitro and in vivo studies...

BACKGROUND: Surgical biopsy of metastatic lesions followed by pathological confirmation for the investigation of biomarkers is occasionally proposed as an effective strategy in the treatment of metastatic breast cancer. However, few reports have examined Ki-67 immunohistochemical expression in distant metastatic lesions of breast cancer patients. This study aimed to investigate the clinicopathological significance of subtypes and Ki-67 immunohistochemical expression in metastatic breast cancer lesions...

Nitric oxide has been implicated in biology and progression of glioblastoma (GBM) being able to influence the cellular signal depending on the concentration and duration of cell exposure. NOS2 (inducible nitric oxide synthase) have been proposed as a component of molecular profile of several tumors, including glioma, one of the most aggressive primary brain tumor featuring local cancer stem cells responsible for enhanced resistance to therapies and for tumor recurrence. Here, we investigated the NOS2 mRNA expression by reverse transcription-PCR in human glioma primary cultures at several grade of malignancy and glioma stem cell (GSC) derived neurospheres...

Poor prognosis of glioblastoma multiforme is strongly associated with the ability of tumor cells to invade the brain parenchyma, which is believed to be the major factor responsible for glioblastoma recurrence. Therefore, identifying the molecular mechanisms driving invasion may lead to the development of improved therapies for glioblastoma patients. Here, we investigated the role of procollagen-lysine 2-oxoglutarate 5-dioxygenase 2 (PLOD2), an enzyme catalyzing collagen cross-linking, in the biology of glioblastoma invasion...

The tumor board or multidisciplinary cancer meeting (MCM) is the foundation of high value multidisciplinary oncology care, coordinating teams of specialists. Little is known on how these meetings are implemented in Neuro-oncology. Benefits of MCMs include coordination, direction for complicated cases, education, and a forum for communication, emerging technology, and clinical trials. This study identifies participation and utilization of neuro-oncology MCMs. A cross-sectional descriptive survey was dispersed through an internet questionnaire...

(11)C-methionine (MET) is one of the most commonly used positron emission tomography (PET) tracers for evaluation of malignant brain tumor, with MET-PET being a sensitive technique for visualization of primary and recurrent malignant brain tumors. However, previous reports have demonstrated MET uptake in lesions associated with benign brain diseases. These diseases usually show an increase in MET uptake similar to that of malignant tumors. This pitfall in MET-PET image interpretation is important not only for nuclear medicine professionals, but also for radiologists...

Glioma initiating cells (GICs) are thought to contribute to therapeutic resistance and tumor recurrence in glioblastoma, a lethal primary brain tumor in adults. Although the stem-like properties of GICs, such as self-renewal and tumorigenicity, are epigenetically regulated, the role of a major chromatin remodeling complex in human, the SWI/SNF complex, remains unknown in these cells. We here demonstrate that the SWI/SNF core complex, that is associated with a unique corepressor complex through the d4-family proteins, DPF1 or DPF3a, plays essential roles in stemness maintenance in GICs...

Background: Primary and adaptive resistance against chemo- and radiotherapy, and local recurrence after surgery limit the benefits from these standard treatments in glioma patients. Recently we found that glioma cells can extend ultra-long membrane protrusions, "tumor microtubes" (TMs), for brain invasion, proliferation, and interconnection of single cells to a syncytium that is resistant to radiotherapy. We wondered whether TMs also convey resistance to the other two standard treatment modalities...

Of all brain metastases, the most common primary lesion is derived from the lung. These types of metastases enlarge aggressively with unfavorable prognoses. We report the case of a 75-year-old male patient who had a history of pulmonary resection for Stage IA non-small cell lung cancer(NSCLC), and received chemotherapy. One year after NSCLC surgery, he experienced a cardiogenic cerebral infarction, and anticoagulant therapy was initiated. Mass lesions with hemorrhage were detected bilaterally in the frontal lobes through magnetic resonance imaging three years after the NSCLC surgery...

Metastatic tumors are the most common mass lesions in the brain. This case reports a rare form of sarcoma with metastasis to the brain. The appropriate management of a patient with metastatic alveolar soft part sarcoma to the brain is discussed. Author describes a 32-year-old gentleman diagnosed with primary tumor at gluteus and distant metastases at lower lobe of right lung and the brain. Histopathology proves diagnosis as alveolar soft part sarcoma. Craniotomy with excision of brain lesion was done. Repeated magnetic resonance imaging of the brain after 2 months showed rapidly growing new lesions...

Primary intracranial rhabdomyosarcoma (PIRMS) is a rare neoplasm, which affects infants and young children. We report a rare case of a primary embryonal rhabdomyosarcoma of the cerebellopontine angle in a 7-year-old boy with clinical and radiological features mimicking a vestibular schwannoma. The patient underwent definitive surgery and radiotherapy and is recurrence free at 6 months. PIRMS commonly occur in parameningeal locations or metastasize to the brain from an extracranial primary. Gross total tumor resection followed by adjuvant radiotherapy remains the current standard of treatment; however, chemotherapy has also been tried with favorable results...

Gliomas, and in particular glioblastoma multiforme, are aggressive brain tumors characterized by a poor prognosis and high rates of recurrence. Current treatment strategies are based on open surgery, chemotherapy (temozolomide) and radiotherapy. However, none of these treatments, alone or in combination, are considered effective in managing this devastating disease, resulting in a median survival time of less than 15 months. The efficiency of chemotherapy is mainly compromised by the blood-brain barrier (BBB) that selectively inhibits drugs from infiltrating into the tumor mass...

Glioblastoma multiforme is the most aggressive primary brain tumour. Treatment is largely palliative, with current strategies unable to prevent inevitable tumour recurrence. Implantable micro-electromechanical systems are becoming more feasible for the management of several human diseases. These systems may have a role in detecting tumour recurrence and delivering localised therapies. One potential therapeutic tool is ultraviolet (UV) light. This systematic review assesses the effects of UV light on glioma cells...

Intratumoral heterogeneity (ITH) has increasingly being described for multiple cancers as the root cause of therapy resistance. Recent studies have started to explore the scope of ITH in glioblastoma (GBM), a highly aggressive and fatal form of brain tumor, to explain its inevitable therapy resistance and disease relapse. In this review, we detail the emerging data that explores the extensive genetic, cellular and functional ITH present in GBM. We discuss current experimental models of human GBM recurrence and suggest harnessing new technologies (CRISPR-Cas9 screening, CyTOF, cellular barcoding, single cell analysis) to delineate GBM ITH and identify treatment-refractory cell populations, thus opening new therapeutic windows...

PURPOSE: Glioblastomas (GBM) comprise 17% of all primary brain tumors. These tumors are extremely aggressive due to their infiltrative capacity and chemoresistance, with glial-to-mesenchymal transition (GMT) proteins playing a prominent role in tumor invasion. One compound that has recently been used to reduce the expression of these proteins is shikonin (SHK), a naphthoquinone with anti-tumor properties. Temozolomide (TMZ), the most commonly used chemotherapeutic agent in GBM treatment, has so far not been studied in combination with SHK...

Pediatric glioblastoma (pedGBM) is an extremely aggressive pediatric brain tumor, accounting for ~6% of all central nervous system neoplasms in children. Approximately half of pedGBM harbor recurrent somatic mutations in histone 3 variants or, infrequently, IDH1/2. The remaining subset of pedGBM is highly heterogeneous, and displays a variety of genomic and epigenetic features. In the current study, we aimed to further stratify an H3-/IDH-wild type (wt) pedGBM cohort assessed through genome-wide molecular profiling...
