Filter by:Patients with lung cancer and brain metastases undergo HA-WBRT-SIB using image-guided radiotherapy, receiving a total dose of 30-36 Gy delivered in 18-20 fractions to the whole brain (CTV), while the dose to the GTV is boosted to 44 Gy-52 Gy in 18-20 fractions, five times a week. The optimal mean dose (Dmean) to the bilateral hippocampus should optimally be ≤ 8 Gy, with a mandatory maximum dose (Dmax) to the hippocampus not exceeding 10 Gy; the preferred Dmean to the hippocampus PRV should optimally be ≤ 9 Gy, while the mandatory Dmax to the hippocampus PRV should be ≤ 12 Gy. The HVLT-R immediate recall scores are obtained at baseline and 1, 3, and 6 months after treatment.
PRIMARY OBJECTIVE To establish feasibility and acceptability of diagnostic brain MRI in young children for specified indications using an upright MRI system without sedation or anaesthesia. SECONDARY OBJECTIVES To establish how young children who undergo brain MRI using upright MRI view the experience To establish how parents / carers of young children who undergo brain MRI using the upright MRI view the experience for their child and for themselves. To establish how image quality compares between brain MRI using the upright MRI scanner and the standard MRI scanner used in clinical practice.
Positron emission tomography (PET) is a diagnostic imaging technique that uses positron emission (e-) to image changes in diagnosed tissues. Detector systems are an important part of PET scanners. They can convert gamma photons into fluorescent photons to obtain information about energy, time and position, of the gamma photons obtained through the use of an appropriate positron-emitting radiopharmaceutical. Conventional PET scanners are expensive mostly because they require the use of LSO (lutetium oxyorthosilicate) or LYSO (lutetium yttrium oxyorthosilicate) scintillation crystals. Such crystal scintillators are very costly and difficult to obtain, which limits accessibility of the PET- scanners. The prototype J-PET scanner tested in this trial uses plastic scintillators in which different physical phenomena occur compared to crystal scintillators. In addition, the J-PET scanner prototype is equipped with unique software enabling three-photon imaging, based on the annihilation resulting from the formation of the orto-positronium (o-Ps) in diagnosed tissue. The aim of this study is to demonstrate the clinical acceptability of such scanners based on plastic scintillators, which can additionally collect and process information on the lifetime of o-Ps derived from routinely used radiopharmaceuticals. Additionally, the aim of this study is to demonstrate the use of the new diagnostic indicator "positronium biomarker" in a prospective study, compared to routine diagnostic scanning.
The aim of this study was to assess the anxiolytic and sedative effect of OZALIN® / OZASED® (ADV6209) 0,25mg/Kg in children undergoing magnetic resonance imaging (MRI) under inhalational anesthesia. Our hypothesis is that compared to children who do not receive any premedication, palatability of OZALIN® / OZASED® by allowing an easier acceptance of the drug, improves the quality of anesthesia induction and postoperative behavioral outcome improving sedation and reducing the need for inhalation anesthetic which has been recognized as the main cause of post-procedural behavioral changes, including emergence agitation.
PSMA is a transmembrane protein specifically expressed in the vascular endothelium of malignant brain tumors, most notably glioblastoma and not in healthy brain parenchyma. It has been shown to be involved in (neo)angiogenesis and endothelial cell invasion. By means of 68Ga-labeled PSMA ligands, investigators are able to non-invasively visualize/quantify PSMA expression in glioblastoma (neo)vasculature in vivo by means of PET. The primary aim of this study is to confirm PSMA as suitable diagnostic and potential theranostic target in patients with intra-axial brain tumors by means of [68Ga]Ga-PSMA-HBEC-CC ([68Ga]Ga-PSMA-11) PET. The secondary aim is to assess whether uptake is increased with intra-arterial injection in those tumors that show uptake after intravenous injection of [68Ga]Ga-PSMA-11.
This was a retrospective, noninterventional cohort study of patients with a confirmed diagnosis of metastatic NSCLC with MET Exon 14 skipping mutation and brain metastases (BM) who received treatment with capmatinib in real-world practice settings. The study population consisted of patients with histologically confirmed stage IIIB, IIIC, or IV MET Exon 14 skipping mutated NSCLC with BM. The date of the initiation of therapy with capmatinib after the date of initial BM diagnosis at or after the initial advanced or metastatic NSCLC diagnosis defined the study index date. The 12-month period before the study index date defined the baseline period to assess baseline demographic and clinical characteristics. Study measures were assessed at the index and during the baseline and postindex date periods. The index date needed to occur between 1 May 2020 and the date of data abstraction, provided the selected patients meet the requirement of a minimum of 6 months follow-up time available after capmatinib initiation; the exceptions to this are those patients who died during this period.
With a trend for increased survival in patients with Brain and Central Nervous System (CNS) cancers, emphasis is increasingly shifting to improving the quality of life of survivors. Performance status (a quantification tool used in patients with cancer to assess their quality of life and ability to carry out activities of daily living) is a key prognostic factor in Brain and CNS cancers and a good performance status is used in determining whether a patient is offered adjuvant treatment with chemotherapy and radiotherapy following primary surgical treatment. The performance status of a patient is defined by physical and cognitive functioning, and the beneficial effect of aerobic exercise in improving physical functioning (e.g., cardiorespiratory fitness) is well established. Thus, it is anticipated that implementing a supervised moderate intensity aerobic exercise training programme will improve the performance status of patients. An implication of this work is that, exercise regimens could be offered as additional treatment, alongside chemotherapy and radiotherapy, which might increase the chance of survival. The project design is a randomised controlled trial with two arms in which one group of patients will undergo an aerobic exercise program starting one week before surgery and continuing for three weeks in the post-operative period. Patients enrolled in this trial will continue with standard treatment including neuro-rehabilitation. The control group of patients will be given written instructions on performing flexibility and stretching exercises in addition to their usual care (including neuro-rehabilitation). The primary outcome is performance status as defined by measurements of physical functioning and cognitive ability (e.g., memory, attention, information processing speed). Physical functioning will be assessed by a timed walking test, hand-grip dynamometry and a maximum jump height test. Other measures of well-being will be assessed; including heath related quality of life using the European Quality of Life-5 Dimensions (EQ-5D) and Functional Assessment of Cancer Therapy- Brain (FACT-Br) questionnaires. Secondary outcome measures will be measurements of mood, fatigue and certain biochemical parameters, such as C-reactive protein (CRP), plasma viscosity (PV), full blood count (FBC), uric acid, insulin-like growth factor 1 (IGF-1), and insulin-like growth factor binding protein 3 (IGFBP-3). It is anticipated that a total of 30 patients will be recruited split between the two groups and each participant will not spend more than four weeks in taking part in the study.
This study was conducted to evaluate the effect of home care planned according to Orem on self-care agency and care burden in brain tumor patients and their caregivers. The study was performed with patients who underwent surgery for a brain tumor and their caregivers in the neurosurgery clinic of a tertiary hospital. Ethical committee approval, institutional permission, patients and their caregiver verbal and written consent were obtained. According to Orem's nursing theory, home care practice combining education, counseling and nursing care started with pre-operative education in the hospital for the patients and caregivers in the intervention group and continued at home with 5 home visits in a 6-month period. Self-Care Agency Scale, MD Anderson Symptom Inventory Brain Tumor-Turkish Form and Caregiver Burden Scale were used as measurement tools in the study.The value of p<0.05 was accepted statistically significant in the data analyses.
The aim of this prospective observational study is to identify the specific reasons that prolong a hospital stay after elective tumor craniotomy. Optimal postoperative in-hospital stay is considered to be two days from surgery to discharge from the neurosurgical ward. However, a variable length of stay at a neurological department for follow-up of late recognized deficits of neurological consequences of the surgical procedure are common.
The investigators aimed to research the incidence of hyperlactatemia in craniotomy cases, the relationship of lactate elevation with tumor type and other factors that may be related, and whether the general anesthesia method applied (inhalation anesthesia or total ıntravenous anesthesia) affects lactate level.
