The goal of this study is to develop better methods of diagnosis, localization, and treatment for pheochromocytomas. These tumors, which usually arise from the adrenal glands, are often difficult to detect with current methods. Pheochromocytomas release chemicals called catecholamines, causing high blood pressure. Undetected, the tumors can lead to severe medical consequences, including stroke, heart attack and sudden death, in situations that would normally pose little or no risk, such as surgery, general anesthesia or childbirth. Patients with pheochromocytoma may be eligible for this study. Candidates will be screened with a...
MRI is used in clinical routine for diagnosing brain tumors, but has limitations in identifying tumor grade, true tumor extension and differentiate viable tumor tissue from treatment induced changes and recurrences. Amino acid PET has demonstrated a great potential for defining true tumor volume, differentiate viable tumor tissue from postoperative changes or radiation necrosis, selection of biopsy site, non-invasive grading of gliomas and for treatment planning and therapy response assessment. By combining PET with MRI, the diagnostic accuracy can improve significantly for these patients. More research is however needed to compare...
This clinical research will evaluate the diagnostic potential of fluorescein as visualized through an operating microscope relative to 1) contrast enhancement on co-registered preoperative MR scans, 2) intraoperative ALA-induced PpIX fluorescence and 3) gold-standard histology obtained from biopsy sampling during the procedure. Subjects will include those people with operable brain tumor with first-time presumed pre-surgical diagnosis of high-grade glioma or low-grade glioma.
Background: - Pleuropulmonary blastoma (PPB) is a rare fast-growing lung tumor that is associated with other, rare tumor types. Most cases of PPB appear in children younger than 6 years of age. Recently, it has been shown that this condition can be inherited (e.g., mutation of the DICER1 gene). Researchers are studying both clinical and genetic aspects of this newly described condition. They are interested in collecting further medical history and genetic information on individuals and close relatives of individuals who have PPB or other rare associated tumors. Objectives: - To study individuals with a personal or...
This research trial studies the effects of diet in patients with a history of melanoma. We are studying the impact of 2 different diets; a whole-foods, fiber-rich diet and a ketogenic diet. Participants will be assigned to one of these diets. During this study, participants will be provided all food at no cost for the entire 6-week study. Food can be picked up or shipped to the participant's home. However, participants will need to come into MD Anderson Cancer Center in Houston, TX, for the initial screening visit and for blood tests every 2 weeks during the study.
In this study the investigators wish to describe the cohort of pediatric patients suffering from neuroblastoma and treated with Dinutuximab and to compare the costs and quality of life between the two French centers, the University Hospital of Strasbourg (HUS) and the Oncopole of Toulouse.
This phase III trial tests how well the addition of dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy works for treating children with newly diagnosed high-risk neuroblastoma. Dinutuximab is a monoclonal antibody that binds to a molecule called GD2, which is found on the surface of neuroblastoma cells, but is not present on many healthy or normal cells in the body. When dinutuximab binds to the neuroblastoma cells, it helps signal the immune system to kill the tumor cells. This helps the cells of the immune system kill the ...
DNA methylation is one of the important ways of protein post-translational modification.Pituitary adenoma (PA) is a benign neuroendocrine tumor that originates from adenohypophysial 45 cells, and accounts for 10%-20% of all primary intracranial tumors. However some PAs can present with high invasiveness and irregular growth, which tend to compresses the optic chiasm and third ventricle, encase the internal carotid artery, and affect hormone secretion from the pituitary gland and hypothalamus. In this study we focus on the mechanism of DNA methylation on the invasiveness of pituitary tumors.
This is a phase 1, first-in-human, open-label, multicenter, dose escalation and expansion study of DLL3-targeted chimeric antigen receptor T-cells in subjects with extensive stage small cell lung cancer or large cell neuroendocrine lung cancer.
This phase I trial studies the side effects and best dose of cord blood-derived expanded allogeneic natural killer cells (donor natural killer [NK] cells) and how well they work when given together with cyclophosphamide and etoposide in treating children and young adults with solid tumors that have come back (relapsed) or that do not respond to treatment (refractory). NK cells, white blood cells important to the immune system, are donated/collected from cord blood collected at birth from healthy babies and grown in the lab. Drugs used in chemotherapy, such as cyclophosphamide and etoposide, work in different ways to stop the growth...
