Filter by:This expanded access is the best available therapy/compassionate use designed to determine the palliative benefit and toxicity of 131I-MIBG in patients with relapsed/refractory neuroblastoma or metastatic pheochromocytoma who are not eligible for therapies of higher priority. Patients may receive a range of doses depending on stem cell availability and tumor involvement of bone marrow. Response rate, toxicity, and time to progression and death will be evaluated.
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.
PET (positron emission tomography) scans combined with a radioactive tracer will be used to identify and analyze tumors. Currently, the most common tracer used to analyze neuroblastoma tumors is called 123I-mIBG. However, the picture it provides is not always clear enough to see the very small areas of the disease. 18F-DA (18F-fluorodopamine) has been shown to be safe and more effective than 123I-mIBG in analyzing the tumor pheochromocytoma, which is closely related to neuroblastoma. With this research study, the investigators plan to meet the following goals: - Investigate to see if 18F-DA is safe to administer to pediatric patients with known or suspected neuroblastoma or pheochromocytoma - Examine where in the body 18F-DA goes. - Obtain information comparing 18F-DA to 123I-mIBG to see if 18F-DA could replace 123I-mIBG in the future. About 20 people, with known or suspected neuroblastoma or pheochromocytoma, will take part in this Pilot study at St. Jude.
The purpose of this study is to investigate the pathologic features, complications, and prognostic factors of functioning adrenal adenoma and suggest follow-up algorithms for adrenal incidentaloma.
Target population: Patients with (1) newly diagnosed or (2) past history of pheochromocytomas and paragangliomas (PPGL) or (3) carrier of genetic mutations in known PPGL susceptibility genes. International multicenter prospective cohort study with randomized intervention (special care follow-up vs. standard care follow-up). All patients will receive instructions about follow-up at the time point of study inclusion. Patients randomized to the standard care follow-up group will be advised to return annually for follow-up according to current routine practice (without active re-scheduling). In contrast, patients randomized to the special care follow-up group will also be advised to return annually for follow-up but these patients will be actively invited, re-scheduled and reminded by the centers to meet scheduled follow-up appointments.
Background: Pheochromocytoma and paraganglioma are rare tumors. They usually form inside and near the adrenal gland or in the neck region. Not all these tumors can be removed with surgery, and there are no good treatments if the disease has spread. Researchers think a new drug may be able to help. Objective: To learn the safety and tolerability of Lu-177-DOTATATE. Also, to see if it improves the length of time it takes for the cancer to return. Eligibility: Adults who have an inoperable tumor of the study cancer that can be detected with Ga-68-DOTATATE PET/CT imaging Design: Participants will be screened with a medical history, physical exam, and blood tests. Eligible participants will be admitted to the NIH Clinical Center. Participants will get the study drug in an intravenous infusion. They will get 4 doses, given about 8 weeks apart. Between 4 and 24 hours after each study drug dose, participants will have scans taken. They will lie on their back on a scanner table. Participants will have vital signs taken. They will give blood and urine samples. During the study, participants will have other scans taken. Some scans will use a radioactive tracer. Participants will complete quality of life questionnaires. Participants will be contacted by phone 1-3 days after they leave the Clinical Center. They will then be followed every 3 to 6 months for 3 years or until their disease gets worse.
Pheochromocytoma is a rare, catecholamine (ex. adrenaline) secreting tumor that requires preoperative alpha blockade to minimize intraoperative hemodynamic instability, thereby reducing intra- and postoperative morbidity and mortality. Phenoxybenzamine is a non-selective alpha blocker that is significantly more expensive and is associated with increased adverse effects in comparison with selective alpha blockers such as doxazosin. Retrospective studies show minimal differences in hemodynamic instability and no differences in postoperative morbidity and mortality between selective vs. non-selective alpha blockers. This study is a randomized controlled trial that will compare hemodynamic instability, morbidity, mortality, cost, and quality of life between patients blocked with phenoxybenzamine vs. doxazosin.
Background: Wild-type gastrointestinal stromal tumor (GIST) is a cancer in the esophagus, stomach, or intestines. It does not respond well to standard chemotherapy or radiation therapy. Most people with GIST are treated with imatinib. But it may not work in many children with GIST. Researchers think the drug SGI-110 may help treat people with GIST, pheochromocytoma and paraganglioma (PHEO/PGL), or kidney cancer related to hereditary leiomyomatosis and renal cell carcinoma (HLRCC). Objective: To learn if SGI-110 causes GIST tumors to shrink or slows their growth. Also to test how it acts in the body. Eligibility: People ages 12 and older who have GIST, PHEO/PGL, or HLRCC that has not responded to other treatments Design: Participants will be screened with: - Physical exam - Urine tests - Computed tomography (CT) or magnetic resonance imaging (MRI), or fluorodeoxyglucose (FDG)-positron emission tomography (PET) scan: A machine takes pictures of the body. - Blood tests Participants will be injected with SGI-110 under the skin each day for 5 days. This cycle will repeat every 28 days. The cycles repeat until their side effects get too bad or their cancer gets worse. Participants will have tests throughout study: - Physical exam and blood and urine tests before each cycle - Blood tests on days 1, 7, 14, and 28 of the first cycle. - Scans before cycle 1 and then every other cycle. - Questionnaires about their pain and quality of life - Tumor biopsy for those 18 and older: A needle removes a small piece of tumor. After they stop treatment, participants will have a final visit. This includes an evaluation of their health, pain, and quality of life. ...
Pheochromocytomas and paragangliomas are neural crest-derived tumors of the nervous system that are often inherited and genetically heterogeneous. Genetic screening is recommended for patients and their relatives, and can guide clinical decisions. However, a mutation is not found in all cases. The aims of this proposal are to: 1) to map gene(s) involved in pheochromocytoma, and 2) identify genotype-phenotype correlations in patients with pheochromocytoma/paraganglioma of various genetic origins.
Collaboration between the surgeon and the anesthesiologist is key for delivering a safe pheochromocytoma surgery. This study aims to establish the collective performance of surgeon-anesthesiologist team by quantifying the relationship between their previous collaborations and patient complications.
