Neurocognitive Decline in Patients With Brain Metastases
The phase I component of the study is to identify maximal tolerated dose (MTD). The phase II is to evaluate neurocognitive decline.

Neurocognitive Function After Proton Therapy in Children and Adolescents
Brain tumors are the second most frequent malignant diseases in children and adolescents. In the study the short and medium term consequences of proton therapy on cognitive processes in particular on executive functions in pediatric patients shall be highlighted/analysed/evalutated. In a second step, these results are to be compared with 1. a group of children and adolescents who had only /exclusively had operative therapy and 2. with a healthy control group. Thus, the extent to which these treatment options differ in terms of their short and medium-term effect is assessed. Methods of neurocognitive/neurophysiology...

Neurocognitive Functioning With Genu-Sparing Whole Brain Radiation Therapy for Brain Metastases
This is a trial that evaluates the preservation of cognition and neuropsychiatric function following genu-sparing whole brain radiation in patients with brain metastases.

Neurocognitive Impact and Dose-Effect Relationship of Hippocampal Avoidance During Whole Brain Radiotherapy Plus Simultaneous Integrated Boost - A Prospective Follow-up Study
For newly-diagnosed patients with brain metastasis, whole brain radiation therapy (WBRT) probably remains a common palliative management even for those with oligometastatic brain disease. However, WBRT-related late sequelae, particularly a decline in neurocognitive functions (NCFs), are a major concern. More importantly, in patients with limited brain metastases and a fair/good performance status, sparing the radiosensitive and vulnerable structures which are responsible for essential NCFs during the WBRT course is one of the reasonable strategies to postpone and prevent the development of WBRT-induced neurocognitive impairments....

Neurocognitive Impact of Different Irradiation Modalities for Patients With Grade I-II Skull Base Meningioma:
For the purpose of this research, investigator will constitute several cohorts of patients, treated either by intensity-modulated radiotherapy, stereotactic radiotherapy or proton-therapy. This will allow better understanding the cognitive and anatomical damages caused by new radiotherapy techniques and better understanding how ionising radiation (X-rays or protons) acts in the long term on brain tissue. Longitudinal follow-up will be multimodal, based on yearly multi-parametric brain MRI to assess morphological changes, in relation with dosimetric data as well as neuropsychological performances, health-related quality of life, ...

Neurocognitive Outcome of Bilateral or Unilateral Hippocampal Avoidance WBRT With Memantine for Brain Metastases
Brain metastases are the most common brain tumors in adults. It is estimated that around 10-30% of cancer patients would develop brain metastases during the course of their illness. Whole brain radiotherapy (WBRT) is the treatment of choice for the majority of patients with brain metastases. WBRT yields high radiologic response rate (27~56%) and is effective in rapid palliation of neurologic symptoms as well as prolongs time to neurocognitive function decline caused by intracranial lesions. By using conventional fractionation, more than one- third of patients developed late neurocognitive toxicity while memory impairment was the most ...

Neurocognitive Outcomes After Whole Brain Radiation Therapy for Hematologic Malignancies
This study assesses neurocognitive outcomes after receiving radiation therapy to the brain (whole brain radiation therapy) in patients with blood cancers (hematologic malignancies). This may help researchers learn more about the effects of whole brain radiation therapy on memory and thinking in patients with blood cancer.

Neuroendocrine Transformation in RB1/TP53 Inactivated NSCLC
Histology transformation from non-small cell lung cancer (NSCLC) to neuroendocrine carcinomas (NEC), especially from epidermal growth factor receptor (EGFR) mutant lung adenocarcinoma (LADC) to small cell lung cancer (SCLC), is widely recognized as a rare mechanism for NSCLC to confer tyrosine kinase inhibitors (TKIs) resistance. The probability of its occurrence is about 3-14% in NSCLC patients who are resistant to TKI treatment. In addition to EGFR mutations, NSCLC patients carrying ALK/ROS1 mutations and receiving corresponding TKI treatment may also experience NEC transformation(NET). In a previous study [Pubmed ID: 35609408],...

Neurofibromatosis (NF) Registry Portal
The NF Registry is a database of patient-reported symptoms, treatments, and experiences with their neurofibromatosis disease. It is a contact registry to relay clinical trial opportunities to targeted patient subgroups, and to supply de-identified disease data to researchers. It has the potential to become a natural history resource.
