The purpose of this study is to determine why up to 25% of the pediatric patients who have surgery for a tumor in the posterior fossa develops the Cerebellar Mutism Syndrome (CMS). Furthermore the purpose is to explore the clinical course and the best treatment of the syndrome.
This study examines cerebrospinal biomarkers in patients with brain tumors. A biomarker is a measurable indicator of the severity or presence of your disease state. Collecting and storing samples of cerebrospinal fluid from patients with brain tumors to study in the laboratory may help doctors develop new strategies to better diagnose, monitor, and treat brain tumors.
Neuroendocrine tumours (NETs) are slow growing cancers, which commonly present as metastatic incurable disease. Some neuroendocrine tumours, termed functional NETs, overproduce hormones which result in a variety of symptoms. However, approximately 75% of NETs are considered non-functional meaning that they do not result in hormone overproduction. The main treatment for both functional and non-functional NETs is somatostatin analogues (SSA, a type of inhibitory hormone). These drugs slow tumour growth and reduce hormone production. Over time, the majority of patients will experience tumour growth despite treatment with SSA therapy. When this occurs, the addition of Peptide Receptor...
Low grade gliomas (LGGs) are malignant, infiltrative and incurable brain tumours that typically present in the younger population. This project proposes to use non-contrast metabolic "Saturation Transfer" (ST)-MRI to evaluate LGG tumour progression and aims to predict early changes in LGG. Early identification of LGG patients whose tumours will progress will permit early interventions. ST-MRI does not involve any intravenous injection of contrast and which acquires metabolic information not seen by standard MRI.
This is an observational case-control study to train and validate a genome-wide methylome enrichment platform to detect multiple cancer types and to differentiate amongst cancer types. The cancers included in this study are brain, breast, bladder, cervical, colorectal, endometrial, esophageal, gastric, head and neck, hepatobiliary, leukemia, lung, lymphoma, multiple myeloma, ovarian, pancreatic, prostate, renal, sarcoma, and thyroid. These cancers were selected based on their prevalence and mortality to maximize impact on clinical care. Additionally, the ability of the whole-genome methylome enrichment platform to detect minimal residual disease after completion of cancer...
This study is for patients who have had surgery to remove brain metastasis and are planned to have stereotactic radiosurgery (SRS) after their brain surgery. It will be optional for patients to have a pre-surgery 18F-Fluciclovine PET/CT scan. The goal of the study is to determine whether a specific imaging agent, known as 18F-Fluciclovine, will help physicians evaluate the extent of surgery and determine if there is any visible tumor above what MRI alone can identify as well as improve the physicians' ability to detect recurring disease. This agent (18F-Fluciclovine) is investigational for the imaging of brain metastases.
The goal of this observational study is to characterize the circulating leukocyte profile and the immune T cells distribution within the tumor in patients with malignant brain tumors and to correlate these findings with the oncological outcome. Participants will be subjected to blood sampling before surgery and for 12 months of follow-up. Additional sampling and analysis will be performed on tumor samples.
Background: - Researchers are interested in studying individuals who have known or suspected metabolic or genetic diseases that put them at a high risk for heart diseases or diseases of their blood vessels. To improve the results of the study, both affected and nonaffected individuals will be asked to provide blood and other samples and will undergo tests to evaluate heart and lung function. Nonaffected individuals will include relatives of affected individuals and healthy nonrelated volunteers. Objectives: - To study individuals who have or are at risk for cardiovascular diseases, as well as their unaffected relatives and healthy...
The aim of this study is to study T-cells. Blood will be collected and the samples will be used to generate T cell clones. Two separate blood draws will be required at the maximum.
The patients are being asked to take part in this clinical trial because they received cancer treatment as a child at St. Jude. The study comprehensively examines sleep among three distinct diagnostic groups of survivors in the SJLIFE cohort: ALL, CNS tumors, and non-CNS solid tumors. Primary Objective The primary aim of this protocol is to estimate the prevalence of various sleep disorders among long-term survivors of childhood ALL, CNS tumors, and non- CNS solid tumors. Exploratory Objective The exploratory objective of the study is to explore associations between the prevalence of sleep disorders and clinical outcomes collected in SJLIFE.
