Active clinical trials for "Pheochromocytoma"

Pheochromocytomas and paragangliomas (PPGL) are rare tumors treated by surgical excision. During follow-up, more than 15% of patients will have recurrences in the form of new tumors, locoregional recurrence or metastases. This subgroup is initially not identifiable. It is therefore usual to perform annual monitoring of all patients throughout their lives by questioning and measuring blood pressure during a medical consultation and by measuring urinary or plasma metanephrines and normetanephrines. The main objective of this prospective monocentric study is to evaluate the reliability of an optimized remote monitoring program in comparison to a usual in-clinic monitoring of patients surgically-cured and tumor-free at the time of inclusion.

Sudden Cardiac Death is a leading cause of mortality and remains a major public health burden worldwide. Cardiac arrest due to coronary heart disease explains a large proportion of the cases, but if autopsy is not performed the exact underlying cause remains obscure in many adults who face sudden death outside heath care organizations. The investigators aim to find proof that primary aldosteronism is a risk factor for sudden death and to characterize the prevalence of adrenal pathology in sudden death of undetermined cause in a case-control study. In addition, the study aims to characterize the prevalence of other adrenal pathology i.e. silent adenomas, cortisol-producing adenomas and pheochromocytomas in sudden death. The investigators also seek evidence that other endocrine hormone overproduction-causing diseases are more prevalent in persons with sudden death compared with those experiencing traumatic or suicidal death sudden death.

Multiple endocrine neoplasia type 2A (MEN2A) is a rare syndrome associated with activating mutations in the RET proto-oncogene, combining medullary thyroid cancer in approximately 100% of cases and pheochromocytoma in 10-80% of cases. While it is accepted that the RET mutation causes variable penetrance of pheochromocytoma in the MEN2A patient population, there is no pathophysiological explanation for the phenotypic variability among patients with the same mutation, including within the same family. The aim of this study is to better characterise the genetic factors that may explain the variable penetrance of pheochromocytoma in MEN2. To this end, the investigatoes plan to perform a whole exome analysis in 2 families carrying the p. Cys634Arg mutation causing NEM2A, followed in Marseille by the principal investigator: the 1st family has 11 members all aged over 35 years, for which 8 are carriers of pheochromocytoma while 3 have not developed it (while their age is higher than the latest age of diagnosis of pheochromocytoma in this family); the 2nd family has 3 members (father and daughter with pheochromocytoma developed before 25 years; son without pheochromocytoma at an age of 42 years). The investigators believe that the analysis of these patients should allow the isolation of variants on genes potentially involved in the genesis of a pheochromocytoma in MEN2.

The goal of this multicenter, observational, analytic, randomized clinical trial is to analyze the laparoscopic and robot-assisted method in the surgical treatment of patients with adrenal diseases. The main question it aims to answer are: to find the superiority of one the the surgical method mentioned above to compare the quality of life in patients with adrenal mass before surgery and after laparoscopic or robotic-assisted adrenalectomy.

NOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility criteria for this study as shown in the Eligibility Section, you may enroll regardless of the results of your clinical genetic testing. While it is well recognized that hereditary factors contribute to the development of a subset of human cancers, the cause for many cancers remains unknown. The application of next generation sequencing (NGS) technologies has expanded knowledge in the field of hereditary cancer predisposition. Currently, more than 100 cancer predisposing genes have been identified, and it is now estimated that approximately 10% of all cancer patients have an underlying genetic predisposition. The purpose of this protocol is to identify novel cancer predisposing genes and/or genetic variants. For this study, the investigators will establish a Data Registry linked to a Repository of biological samples. Health information, blood samples and occasionally leftover tumor samples will be collected from individuals with familial cancer. The investigators will use NGS approaches to find changes in genes that may be important in the development of familial cancer. The information gained from this study may provide new and better ways to diagnose and care for people with hereditary cancer. PRIMARY OBJECTIVE: Establish a registry of families with clustering of cancer in which clinical data are linked to a repository of cryopreserved blood cells, germline DNA, and tumor tissues from the proband and other family members. SECONDARY OBJECTIVE: Identify novel cancer predisposing genes and/or genetic variants in families with clustering of cancer for which the underlying genetic basis is unknown.

This phase II trial studies how well pazopanib hydrochloride works in treating patients with advanced or progressive malignant pheochromocytoma or paraganglioma. Pazopanib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of indium In 111 pentetreotide in treating patients who have refractory cancer.

This study will evaluate the clinical response and safety of cone beam computed-tomography guided percutaneous cryoablation in bone metastases from thyroid, adrenal and neuroendocrine tumors in 30 patients.

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. ...

RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This phase II trial is studying how well internal radiation therapy works in treating patients with liver metastases from neuroendocrine tumors.
