Corticotrophin-releasing Hormone (CRH) Stimulation for 18F-FDG-PET Detection of Pituitary Adenoma in Cushing s Disease
Background: Cushing s disease is caused by a pituitary gland tumor. Patients with Cushing s disease suffer obesity, diabetes, osteoporosis, weakness, and hypertension. The cure is surgery to remove the pituitary tumor. Currently, MRI is the best way to find these tumors. But not all tumors can be seen with an MRI. Researchers hope giving the hormone CRH before a PET scan can help make these tumors more visible. Objective: To test whether giving CRH before a PET scan will help find pituitary gland tumors that might be causing Cushing s disease. Eligibility: People ages 8 and older with Cushing s disease...

Cytokine-induced Killer Study for Patients With Stage II Melanoma
For investigators' current experimental clinical trial, patients are given 4 injections of ipilimumab, given 3 weeks apart x 4 injections with or without cytokine-induced killer therapy. Investigators propose to test this dual therapy in patients with melanoma who have known stage I, metastatic melanoma. Investigators hypothesize that this form of combinatorial immunotherapy will result in tumor stabilization or shrinkage, significant prolongation of progression-free, disease-free or overall survival compared to the use of ipilimumab alone

Defibrotide Prophylaxis of Transplant Associated-Thrombotic Microangiopathy for Neuroblastoma
This phase II trial tests how well defibrotide works in preventing transplant-associated thrombotic microangiopathy (TA-TMA) in patients with high-risk neuroblastoma undergoing tandem transplants (hematopoietic stem cell transplant [HSCT]). TMA is a potential life-threatening complication of stem cell transplant. TMA is a possible side effect of the chemotherapy (conditioning regimen) patients receive to help treat high-risk neuroblastoma, because these medicines can sometimes damage the blood vessel walls in the body. This damage leads to formation of tiny blood clots in organs, especially the kidney. This then causes organ damage...

Defining the Clinical Potential of Mass Response as a Biomarker for Patient Tumor Sensitivity to Drugs
The primary objective of this study, sponsored by Travera in Massachusetts, is to validate whether the mass response biomarker has potential to predict response of patients to specific therapies or therapeutic combinations using isolated tumor cells from varying cancers and biopsy formats.

Determining Patterns In Study Experiences of Neuroblastoma Patients
Historically, participation in clinical research is highly skewed towards particular demographic groups of people. This study will invite several participants to gather a wide range of information on clinical trial experiences for neuroblastoma patients. The aim of the study is to identify the factors that limit the ability of a person to enroll in, as well as complete a clinical trial for treatment of neuroblastoma. The data collected from this study will help improve future outcomes for all neuroblastoma patients as well as those in under-represented demographic groups.

Development and Progression of Carcinoid Heart Disease in a Cohort of Adult Patients With Neuroendocrine Tumors
Carcinoid Heart Disease (CHD) is a rare form of heart disease, occurring in over 50% of the patients with carcinoid syndrome. Pathophysiology, prognostic factors of development of Carcinoid Heart Disease and progression of disease remain unclear. This observational multicenter cohort study is designed to study the occurrence of Carcinoid Heart Disease in patients with differentiated carcinoid tumors, to describe numerous factors influencing the occurrence, severity, progression and long-term survival of patients with Carcinoid Heart Disease. Basic informations and detailed diagnosis informations (oncological and cardiac...

Development of a Predictive Model for the Risk of Metastatic Disease in PPGLs, a Retrospective Cohort Study
Phaeochromocytomas and paragangliomas (PPGLs) are tumours of the adrenal medulla and extra-adrenal sympathetic nervous system, some which can become metastatic. It is a very rare disease and the tumours are often detected late. Approximately 50 % of the tumours are caused by germline genetic variants screening programmes are recommended for patients and their family members; however, they are not yet well-targeted with respect to individual prognosis. In this study the investigatorscaim to characterize the genotype-phenotype associations in all Danish patients (n=400) diagnosed with PPGLs who have been followed in tertiary centres ...

Development of MRF for Characterization of Brain Tumors After Radiotherapy
The purpose of this study is to discover the potential convenience and ease of using a Magnetic Resonance Imaging (MRI) technique, named Magnetic Resonance Fingerprinting (or MRF), to achieve high-quality images within a short scan time of 5 min for viewing the entire brain. This is an advanced quantitative assessment of brain tissues. This method is being applied with IVIM MRI to be able to tell the difference between a brain with radiation necrosis and a brain with tumor recurrence. Participants will consist of individuals who have received radiation therapy in the past and were diagnosed with radiation necrosis, individuals with...

Dexmedetomidine Versus Magnesium Sulphate in Patients Undergoing Craniotomy for Deeply Settled Intracranial Tumours
An intracranial tumor, is an abnormal mass of tissue in which cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. More than 150 different brain tumors have been documented, but the two main groups of brain tumors are termed primary and metastatic. Primary brain tumors include tumors that originate from the tissues of the brain or the brain's immediate surroundings. Metastatic brain tumors include tumors that arise elsewhere in the body (such as the breast or lungs) and migrate to the brain, usually through the bloodstream Barbiturates, Thiopental and pentobarbital...

Dinutuximab With Chemotherapy, Surgery and Stem Cell Transplantation for the Treatment of Children With Newly Diagnosed High Risk Neuroblastoma
This phase III trial tests how well adding dinutuximab to induction chemotherapy along with standard of care surgery radiation and stem cell transplantation 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 in greater than normal amounts on some types of cancer cells. This helps cells of the immune system kill the cancer cells. Chemotherapy drugs such as cyclophosphamide, topotecan, cisplatin, etoposide, vincristine, dexrazoxane, doxorubicin, temozolomide, irinotecan and isotretinoin, work in different ways to stop the ...
