Filter by:This study was a retrospective observational study. The study included patients with non-small cell lung cancer with ALK-fusion brain metastases or meningeal metastases who received first-line and late-line treatment with the third-generation ALK TKI lorlatinib between June 2022 and June 2023. Data were collected from the electronic medical records database and hospital information system of many hospitals in Sichuan Province. Clinical pathology features including gender, age, ALK mutation status at diagnosis, and clinical stage at diagnosis were collected from the medical records. The physical condition assessed by ECOG-PS before the administration of lorlatinib was recorded. Information on anti-tumor therapy was obtained from the records, including dose and time of ALK-TKI therapy and tumor response, number of prior systemic therapy lines, drug regimen, efficacy, and whether local therapy such as radiotherapy and surgery had been received. In this study, the sample size is not limited, and information is collected according to the maximum number of patients. The study period was from 01 July 2023 to 30 June 2024.
This study is an ambispective cohort study to evaluate the displacement and deformation of large brain metastases (BM) treated with magnetic resonance imaging-guided adaptive radiotherapy (MRIgART)
This study will evaluate whether the combination of sacituzumab govitecan (SG) and bevacizumab will result in shrinkage of brain metastases from patients with non-squamous non-small cell lung cancer (NSCLC), with disease progression on chemotherapy and immunotherapy.
The goal of this Phase 3 clinical trial is to compare the efficacy of niraparib versus temozolomide (TMZ) in adult participants with newly-diagnosed, MGMT unmethylated glioblastoma multiforme (GBM). The main questions it aims to answer are: Does niraparib improve progression-free survival (PFS) compared to TMZ? Does niraparib improve overall survival (OS) compared to TMZ? Participants will be randomly assigned to one of two treatment arms: niraparib or TMZ. - study drug (Niraparib) or - comparator drug (Temozolomide - which is the standard approved treatment for MGMT unmethylated glioblastoma). The study medication will be taken daily while receiving standard of care radiation therapy (RT) for 6-7 weeks. Participants may continue to take the niraparib or TMZ adjuvantly as long as the cancer does not get worse or completion of 6 cycles of treatment (TMZ). A total of 450 participants will be enrolled in the study. Participants' tasks will include: - Complete study visits as scheduled - Complete a diary to record study medication
This study explores whether DESI-MS can be used to identify cancerous vs. noncancerous tissue during brain tumor surgery.
Brain tumors involve different age groups with a wide range of tumor types involving different anatomical compartments of the brain. The evolution of the brain in vertebrates, including the most recent homo species (including humans), has occurred through increasing structural complexity in more evolved species. In the retrospective study, we will investigate the location of the tumors and different structural aspects of skull anatomy in patients with brain tumors. The information will be compared with the anatomical evolution of the brain and skull in vertebrates to look for possible associations, which can provide insights into evolutionary biology.
This phase III trial evaluates whether patient care can be done remotely for patients having cranial (skull) radiation or who have previously had cranial radiation. In addition, this trial compares study outcomes between patients who get metformin and those who do not. Cranial radiation, an essential component of brain tumor treatment, can result in significant negative effects on cognitive (the ability to clearly think, learn, and remember) function. Wearable devices have been used in the field of neurology for seizure detection and assessment of patients with movement disorders. Wearable device technology has also been implemented for remote monitoring of cancer patients and for cancer clinical trials. Metformin is the active ingredient in a drug used to treat type 2 diabetes mellitus (a condition in which the body cannot control the level of sugar in the blood). It is also being studied in the treatment of cancer. Use of metformin may reduce risk of cognitive decline following radiation therapy within the skull (intracranial). These effects may be further strengthen by addition of device-based physical activity promotion. Mayo Test Drive is a web-based platform for remote self-administered cognitive assessment. Using Mayo Test Drive may help determine whether patient care can be done remotely, while simultaneously evaluating benefits of health promotion through use of a wearable watch device and metformin in preventing radiation-related cognitive decline.
To evaluate the efficacy of nilatinib maleate tablets combined with capecitabine in the treatment of HER2-positive advanced esophageal/esophagogastric junction/gastric adenocarcinoma with brain metastasis.
The goal of this clinical investigation of a medical device is to test the safety of graphene based electrodes when used during surgery for resection of brain tumors. The main questions that it aims to answer are: - To understand the safety of these new electrodes when used during brain tumor surgery (primary objective); - To assess the quality of the brain signals recorded with the new electrodes, their ability to stimulate the brain, how stable their function is over the duration of an operation, and their suitability for use in the operating theatre (secondary objectives). Participants will undergo tumor surgery as usual with the study electrodes being tested alongside a standard monitoring system. If they are awake for part of their surgery they may be asked to complete specific tasks such as naming objects from a list modified for the study. They will be monitored subsequently for any complications including undergoing an additional MRI scan 6 weeks after their surgery.
Brain malignancies are the most common cause of death from cancer in the pediatric population and a major source of morbidity amongst survivors. Many children with a brain tumour often suffer from visual field defects (hemianopia) dramatically impacting their daily life with poorer social interaction, difficulties learning, playing sports and engaging with peers. Practically, they bump into people and objects and have problems in finding their way in unfamiliar places and in detecting incoming objects in their blind field. There is growing recognition of the diverse and deep impact of hemianopia on physical and mental health, quality of life, and social outcomes of the affected individuals and their family. However, despite the frequent impact of brain tumours on the visual function and functional vision, ophthalmologic evaluations are not standard of care for all brain tumour patients and there are no standardized protocols of vision loss management in the pediatric population with hemianopia. There is an unmet need of restoring perception in the blind field in individuals with hemianopia consecutive to pediatric brain tumor. Our laboratory has developed a visual rehabilitation procedure based on the combination of adaptative audio and visual target tracking in a 3D environment in virtual reality. Participants perform audiovisual stimulation at home in a headset, with remote control from the laboratory. Preliminary on data on paediatric patients with hemianopia consecutive to a brain tumour indicate feasibility and potential effectiveness of a 6-week Re:Vision program on visual fields, visual perception and quality of life. Our objective is to evaluate the effectiveness of Re:Vision, an 8-week visual telerehabilitation program, on visual perception in 50 individuals aged 10-40 years old with hemianopia consecutive to a pediatric brain tumor in a phase IIa/b multi-centric clinical study across Canada. This intervention provides more equitable access to individuals, with the ability to receive rehabilitation therapy at home without supervision by a healthcare professional, meaning that Canadians living outside urban centres could take advantage of specialized therapies with remote supervision. This is the first study that could lead to a major change in the management of these patients. It could open the door for visual rehabilitation strategies to other population of visually impaired children, significantly impacting public health strategies.
