Filter by:Neuroendocrine tumours (NETs) are generally slow growing, but some can be aggressive and resistant to treatment. Compared to healthy cells, the surface of these tumor cells has a greater number of special molecules called somatostatin receptors (SSTR). Somatostatin receptor scintigraphy and conventional imaging are used to detect NETs. This study proposes 68Gallium(68Ga)-DOTATOC positron emission tomography/computed tomography (PET/CT) is superior to current imaging techniques. The goal is to evaluate the safety and sensitivity of 68Ga-DOTATOC PET/CT at detecting NETs and other tumors with over-expression of somatostatin receptors.
This phase II Pediatric MATCH trial studies how well ensartinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with ALK or ROS1 genomic alterations that have come back (recurrent) or does not respond to treatment (refractory) and may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Ensartinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Background: More than 130 primary tumors of the central nervous system (CNS) have been identified. Most affect less than 1,000 people in the United States each year. Because these tumors are so rare, there are few proven therapies. This study will test whether the immunotherapy drug nivolumab is an effective treatment for people with rare CNS tumors. Objectives: To learn if stimulating the immune system using the drug nivolumab can shrink tumors in people with rare CNS (brain or spine) tumors or increase the time it takes for these tumors to grow or spread. Eligibility: Adults whose rare CNS tumor has returned. Design: Participants will be screened: - Heart and blood tests - Physical and neurological exam - Hepatitis tests - Pregnancy test - MRI. They will lay in a machine that takes pictures. - Tumor tissue sample. This can be from a previous procedure. At the start of the study, participants will have blood tests. They will answer questions about their symptoms and their quality of life. Participants will get nivolumab in a vein every 2 weeks for up to 64 weeks. Participants will have monthly blood tests. Every other month they will have an MRI and a neurologic function test. They will also answer questions about their quality of life. Genetic tests will be done on participants' tumor tissue. Participants will be contacted if any clinically important results are found. After treatment ends, participants will be monitored for up to 5 years. They will have a series of MRIs and neurological function tests. They will be asked to report any symptoms they experience....
This Pediatric MATCH screening and multi-sub-study phase II trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and/or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.
This phase II trial is studying giving radiation therapy together with combination chemotherapy after surgery to see how well it works in treating children with newly diagnosed medulloblastoma.
This phase I trial studies the side effects and best dose of pembrolizumab and to see how well it works in treating younger patients with high-grade gliomas (brain tumors that are generally expected to be fast growing and aggressive), diffuse intrinsic pontine gliomas (brain stem tumors), brain tumors with a high number of genetic mutations, ependymoma or medulloblastoma that have come back (recurrent), progressed, or have not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may induce changes in the body's immune system, and may interfere with the ability of tumor cells to grow and spread.
Adult medulloblastoma is a rare tumour. The "standard risk " group (complete surgery or residual tumour lower than 1,5 cm2, absence of malignant cells in the cerebrospinal fluid, absence of metastasis, absence of MYC amplification and exclusion of large cells medulloblastoma) concerns, for the adult population, a majority of patients at diagnosis (about ¾ of cases). Conventional treatment is classically based on a 54/36 Gy cranio-spinal radiotherapy (54 Gy on the posterior fossa and 36 Gy on the nevraxis). This treatment is associated with an acute toxicity (haematological, cutaneous, digestive and general) wich decreases gradually when patient goes away from the treatment period. For this category of patients and this modality of treatment, The French intergroup experience, pleads in favour of a late and progressive neurotoxicity. This neurotoxicity is associated with a clear degradation of the quality of life. In the light of paediatric studies : We propose a phase II study to estimate the interest of a decrease of radiation doses compensated by a chemotherapy according to the following schedule 1. carboplatine + etoposide based chemotherapy every 28 days x 2 2. followed by, less than 80 days after the surgery, radiation therapy with 24 Gy on the in toto neuro axis and 54 Gy on the post operative bed. The majority of French centres concerned with the neuro-oncology are involved in this trial. About 25 new cases by year are waited. A centralized analysis of pathological slides and of the pre and post surgery Magnetic Resonance Imaging is foreseen. The main objective is to estimate the survival without disease at 1 year Secondary objectives associate the evaluations of the rate of complete response at the end of procedure, the overall survival, the survival without disease, the survival without events, the neurocognitiv toxicity, the endocrine toxicity, the hearing toxicity and the time until definitive deterioration of the quality of life Associated studies Two associated studies are besides foreseen (parallel search for co-financing): 1. A biologic study is planed with the aim to confirm, by morphological, genomic and transcriptomic studies, the interest, for the adult population, of the prognostic markers used in paediatric population 2. A radiological study is planed with the aim to estimate the interest : - of a multimodal follow-up (spectroscopy and perfusion imaging) for the premature detection of recurrences - of the study of functional connectivity in correlation with the neuropsychological follow-up for the analysis of the aetiology and premature markers of neurotoxicity.
Patients with relapsed medulloblastoma, ependymoma and ATRT have a very poor prognosis whether treated with conventional chemotherapy, high-dose chemotherapy with stem cell rescue, irradiation or combinations of these modalities. Antiangiogenetic therapy has emerged as new treatment option in solid malignancies. The frequent, metronomic schedule targets both proliferating tumor cells and endothelial cells, and minimizes toxicity. In this study the investigators will evaluate the use of biweekly intravenous bevacizumab in combination with five oral drugs (thalidomide, celecoxib, fenofibrate, and alternating cycles of daily low-dose oral etoposide and cyclophosphamide), augmented with alternating courses of intrathecal etoposide and cytarabine. The aim of the study is to extend therapy options for children with recurrent or progressive medulloblastoma, ependymoma and ATRT, for whom no known curative therapy exists, by prolonging survival while maintaining good quality of life. The primary objective of the MEMMAT trial is to evaluate the activity of this multidrug antiangiogenic approach in these heavily pretreated children and young adults. Additionally, progression-free survival (PFS), overall survival (OS), as well as feasibility and toxicity will be examined.
This laboratory study is looking at stored tumor samples in young patients with brain tumors. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
The purpose of this study is to test the usefulness of imaging with radiolabeled methionine in the evaluation of children and young adults with tumor(s). Methionine is a naturally occurring essential amino acid. It is crucial for the formation of proteins. When labeled with carbon-11 (C-11), a radioactive isotope of the naturally occurring carbon-12, the distribution of methionine can be determined noninvasively using a PET (positron emission tomography) camera. C-11 methionine (MET) has been shown valuable in the monitoring of a large number of neoplasms. Since C-11 has a short half life (20 minutes), MET must be produced in a facility very close to its intended use. Thus, it is not widely available and is produced only at select institutions with access to a cyclotron and PET chemistry facility. With the new availability of short lived tracers produced by its PET chemistry unit, St. Jude Children's Research Hospital (St. Jude) is one of only a few facilities with the capabilities and interests to evaluate the utility of PET scanning in the detection of tumors, evaluation of response to therapy, and distinction of residual tumor from scar tissue in patients who have completed therapy. The investigators propose to examine the biodistribution of MET in patients with malignant solid neoplasms, with emphasis on central nervous system (CNS) tumors and sarcomas. This project introduces a new diagnostic test for the noninvasive evaluation of neoplasms in pediatric oncology. Although not the primary purpose of this proposal, the investigators anticipate that MET studies will provide useful clinical information for the management of patients with malignant neoplasms.
